Day-118: Politics and Religion
Blog-Chain-Time 2023.11.25-15:56 in Tübingen
Topics: Hypothesis, Racism
While I just want to start a complicated Work for my Dings-Project, that I’ve been putting off for a long Time, a good Friend calls me to discuss some Issues with his current Plans.
After that we come to the Subject of the Israel-Conflict, where my Colleague recommends the Interview Matés-on-Israel-Palestinei, where the Jewish Dr-Gabor_Maté talks to Hanna, who is his Daughter.
Like many of my Friends the Doctor questions the Objectivity of our Mainstream-Media, which for Simplicity I would like to narrow down as follows:
Besides that he really takes a hard Line with his own People and amongst other Things poses the following three Hypotheses:
Not sure if all is 100% correct, but one Thing is clear to me - Racism from whichever Side most of the Time is Bad and instead we should better work together for a GoodLife4All:

Topics: Politics, Religion
After a Talk with My-Black-Forest-Friend on the current Israel-Conflict, he sends me a Link to a YouTube-Video [5] with a Statement of the American Ex-Admiral John_Kirby:
Israel is not trying to wipe the Palestinian People off their Map.
This Opinion then compared by Katy_Halper with a Speech [1] of Netanjahu from End of October 2023:
“You must remember what Amalek has done to you” says our Holy Bible.
We do remember and we are fighting.
I find out, that this is a Quote [2] of the Book-of-Deuteronomy, where it is written:
Don’t forget what Amalek did to you on the Road after you left Egypt, how he attacked you when you were tired, barely able to put one Foot in front of another […]. When GOD, your God, gives you Rest from all the Enemies that surround you in the inheritance-land GOD, your God, is giving you to Possess, you are to wipe the Name of Amalek from off the Earth. Don’t forget!
The Amalek were Nomadic-People, who are said to have had a lot of Trouble with the Israeli-People and probably (as planned by God) got wiped out because of that:
Nevertheless in his Speach Mr-Netanjahu seems to equate the still living Palestinians with the dead Amalek and this is then used by Katy_Halper as a Proof for the Contradiction to the Statement of John_Kirby, which I would summarize to the following Claim:
Mr-Kirby is wrong, because Mr-Netanjahu (indirectly) says: Israel is trying to wipe the Palestinian People off their Map.
After doing some Research on the cited Text in the Internet, I look again into My-Bible, that I read a lot as a Teen-Ager and later used in many Discussions with My-Jehovah’s-Witnesses:
In the First-Book-of-Samuel as well as in the Second-Book-of-Mose I then find two clear Statements [3,4], what our (good) God had in Mind for that (bad) Amalek and because this also could be a Proof of My-God-is-Bad-Hypothethis, I want to hear a second Opinion of Our-Bible-Expert, who has been a Teacher for Religion.
In a long and interesting Talk I learn a lot about the History of the Israeli-People, but I can’t elicit a clear Statement from him about the real Meaning of those problematic Passages.
Nevertheless the Time was worth it, because I got some new Information for My-Doctorial-Thesis, where I finally plan to find out The-Truth - Even if this will be not an easy Task:

Day-116: The Local-Web-App
Blog-Chain-Time 2023.10.30-00:27 in Tübingen
Topics: Ernst-Bloch-Choir, Local-Web-App
As the informed Follower of the Dings-Project knows, I already experienced with different Technologies [0,1] to implement Apps that runs on various Computer-Systems.
For our Program Noch-und-noch-nicht-fertig-werden my Choir-Friend has prepared with Musecore many Mp3-Files for the Learning in the different Vocal-Groups.
Since in our Choir most of the Members are not very experienced with Computers and some of them are already overwhelmed by the Download form our Ernst-Bloch-Web-Site, in Order to make Easy-Life with Computers possible, I upload the Scores together with the Mp3-Files to Google-Drive.
To save Bandwidth, Time, Money and Energy, I also send a short Description, how to make Files offline - Even if this is quite tedious:
Though this looks like an acceptable Solution, nevertheless My-Bass-Colleague, who is also our Web-Master, points out to me, that Sorting by Vocal-Groups might meet more the User-Needs.
This brings me to the Idea (again) to write an App, where the Files can be sorted according different Criterias like Song-Title or Voice-Group.
But this Time I want to write a real Multi-Platform-App, that really runs on every Computer-Device. I had the Idea already half a Year ago to use Java-Script and include all Data into a single Html-File, which easily can be downloaded to Local-Storage and then be run in every Web-Browser.
I want to use a single File, because Goolge and Apple make it really hard for the User to install local Web-Sites with mulitple Files on their Smart-Phones or Tablets - “Honi soit qui mal y pense”.
Though this sounds somehow obvious, up to now I never heard of such Kind of Apps and therefore - just to be sure - I document the Idea again [2] as a Dings-Patent under the Name Local-Web-App-Patent.
If such Apps become widespread, good Speculators go Short with Stocks from Google or Apple and good Investors put their Resources into the Dings-Project:

Day-112: Theory vs. Reality
Blog-Chain-Time 2023.10.19-20:50 at the Piccolo
Topics: Music, Women, Reality
Because of a lot of Traffic, I arrive a little bit late at the Piccolo, where currently the Gig of My-Singing-Teacher takes Place and almost as planned, already at the Entrance I meet My-Artist-Friend - Sometimes I really wonder, if such Coincidences in Theory are Synchronisities in Reality.
But as really planned, I am also pleased to see My-Alt-Choir-Buddy and her Friend - As is known, with the Former I already worked a lot on the Theory of our Pythagorean-Topic.
We sing together with our Coach the second Encore and the very last Addition is then a Solo-Performance again, where at one Point I really got the Impression, that the Voice of my female Teacher almost sounds like a Saxophon - Which cannot be The-Truth of course in Reality.
Because it was a really nice Conclusion for my Day, I thankfully buy from our mobile Florist three nice Roses for three really nice Women, who fortunately really like Flowers and of course the most beautiful One goes to our great Singing-Sax:

Topics: Zero-Wave-Device-Patent, TüDoKop, Women
On our regular TüDoKop-Round I report about My-Patent and the Plan of using a Block-Chain to prevent Others from Stealing the Idea.
After my Friends give me the Advice to better pay for a Patent-Lawyer, I respond that Konrad_Zuse once has said [3], that these are the only Ones, who would earn Money with Patents.
Although this might be true, perhaps I really should to be more careful with such sensitive Things, as also My-Little-Teacher told me around one Hour later:
Blog-Chain-Time 2023.10.16-04:30 in Tübingen
Topics: Zero-Wave-Device-Patent, Nicole, Women
While working out the Description for my Zero-Wave-Device-Patent, I define a lot of new Concepts around the Wave-Theory.
I have long bared my Teeth at the Term Phase and then first get even more confused by a Tip from the funny Sara.
A little bit later, on a Smoking-Round, I must think again on my Nicole and ask via WhatsApp, if Everything is Ok. She responds, that I woke her up, because she forgot to switch off the Smart-Phone.
Almost exactly at that Time in the Bus-Station for our Line-Seventeen, I finally get the decisive Inspiration for my Phase-Problem:
Blog-Chain-Time 2023.10.15-15:25 on a Smoking-Round
Topics: Zero-Wave-Theory
I meet Prof. Dr. Reinhard again and ask him, if he now has some Time for a short Conversation. Unfortunately he currently seems to have a Problem with his Voice and therefore refuses to talk.
After I mention, that I might have a Solution for his Problem, he responds with some Anger, that it is not him, but instead it is me, who has a Problem.
Not sure, if that Statement is related to my Zero-Wave-Theory or perhaps meant in a somehow broader Context.
Blog-Chain-Time 2023.10.13-19:12 in Tübingen
Topics: Zero-Wave-Theory, Zero-Wave-Device-Patent
Because I find the Invention of Zero-Wave-Device very promising, I now file a Draft for my very first Dings-Patent:
But what could be a Solution for a Proof, that I really have been The-First, who had this great Idea?
- The Block-Chain!
Because up to now I have not yet implemented my own Version, for the Time being I use the Git-System, where Sha1-Check-Sums ensure the Consistency of Git-Commits.
My “Git-Block-Chain” can be downloaded by Everybody using with the following Git-Clone-Command to checkout the Zero-Repository:
$ git clone git@github.com:All-Dings/0.git
This creates a Directory “0”, hat contains the complete History for this Repository:
$ ls
0
After the Checkout it is possible to regulary get the latest Updates by first changing into the Zero-Directory …
$ cd 0
… and then issuing the Git-Pull-Command:
$ git pull
remote: Enumerating objects: 4, done.
remote: Total 3 (delta 1), reused 3 (delta 1), pack-reused 0

In case I would change Entries in the History, this Command will fail:
$ git pull
hint: You have divergent branches and need to specify how to reconcile them.
fatal: Need to specify how to reconcile divergent branches.
So for now this is a pragmatic Solution for the Proof of my Work at a given Time and since 2023.04.08 with My-IBM-Room-Mate-Friend I have at least one Person, who already regularily verfies the Zero-Repository.
But of course Everybody else is also invited to become a Witness for The-Truth in the Dings-Project.

Topics: Zero-Wave-Theory, Invention
In Front of the Home-Door I meet our Head-Of-House and seize the Opportunitiy to show her my latest Sinus-Plot. She agrees that my Zero-Wave-Theory sounds reasonable.
After my Complaint, that up to now even the best Experts could not provide a good Explanation for this rather simple Question, she suggests to speak with Crocodile-Dundee, who even owns a Diploma in Physics.
Coincidentally some Minutes later I meet him on a Smoking-Round and we come up with two possible Truths for the missing Energy, namely Elimination or Transformation.
In Order to save our beloved Engergy-Conservatoin-Law, I already defined the Former as Transformation into Zero-Engery, which is carried by Zero-Things. For the Latter my Friend suggests to use the standard Physics-Excuse, namely Trasformation into Heat.
Still not 100% sure about Light-Waves [2], but at least for Sound-Waves, we now have two reasonable Theories:
- Transformation into Heat-Energy
- Transformation into Zero-Energy
Depending on The-Truth, we now can build a Device either for Heating or Cooling, where especially the second Option sounds very promising for fighting our Global-Warming.
But for this Case I give to Consideration, that the Zero-Particles might be channeled somehow into a Parallel-Universe, where they are transformed again into Heat-Energy and then we would unintentionally produce Global-Warming for our Alien-Friends, Damn!
Fortunately my Neighbour-Friend calms me down a bit with the Argument, that the Energy could also be sent to an Dead-Universe without Violation of any Ethic-Rules.
Either cool or not, here the first Concept-Drawing for the Function of my new Invention:

Topics: Zero-Wave-Theory
After a good Meal at the Morra-Imbiss and a theological Conversation with Heisam, on my Way back Home I meet again My-Python-Neighbour, who is by the Way a retired Physics-Teacher.
He speaks to me about the Problem with the Zero-Waves and says that with the Superposition an Interferrence arises, where the (missing) Engery goes and therefore the Energy-Conservation-Law is not violated.
I still have some Doubts and try to explain my View of Things with a “Cigarette-Drawing” on the Walk-Way. I also argue, that there are already Applications of my Zero-Wave-Theory, like Anti-Sound for loud Trucks or Noise-Cancellation in Head-Sets.
For an Explanation of this Technology, here a more accurate Version of my Side-Walk-Plot:
Blog-Chain-Time 2023.10.04-19:51 in Tübingen
Topics: Pythagorean-Comma
After the last Choir-Rehearsal I had a longer Discussion with my Female-Choir-Friend about the old [1] Story of the Pythagorean-Comma. As reported, the Problem seems to be, that the Pure-Fiths do not fit 100% to the Pure-Octaves.
Today I get an E-Mail, where is written, that she calculated the Frequence-Ratio of the 15 Fiths in 7 Octaves using a Frequency-Table:
Aus einer Tabelle habe ich 1,498… berechnet
Sounds reasonable, but better double-check: My Music-Tiger wants to squeeze 12 Fiths into 7 Pure-Ocataves and as all good Mathematicians already know, the Ratio for the Fiths must be $\sqrt[12]{2^7}$.
I enter the Formula into My-Old-Pocket-Calculator and interestingly get a slightly different Result, than my female Choir-Colleague:
Strange, I don’t know the Woman like that, because until now she seemed quite reliable to me. Therefore I write back a short Reply to my dear Music-Sister:
Komisch, ich bin auf 1,499 gekommen, vielleicht ein Rundungs-Fehler?
Then I interrupted my daily Work on the Dings-Project to figure out the Problem. So my Math-Champion wants to put 12 Fiths F into 7 Ocataves O, which can be expressed by the following Equation:
\[F^12 = O^7\]Since my Music-Star wants to keep the Octaves with the Ratio 2:1, we substitue $O$ with $\frac{2}{1} = 2$:
\[F^12 = 2^7\]As we already know, the Exponentiation by Seven can be expanded into a seven-fold continued Multiplication:
\[F^12 = 2 * 2 * 2 * 2 * 2 * 2 * 2\]The Associative-Property of the Multiplication allows us, to use Brackets for making it a bit easier:
\[F^12 = (2*2) * (2*2) * (2*2) * 2\]Then we calculate the Sub-Terms:
\[F^12 = 4 * 4 * 4 * 2\]Let’s add one last Bracket:
\[F^12 = (4 * 4) * 4 * 2\]Now we get the Following:
\[F^12 = 16 * 4 * 2\]High Numbers are Pain-in-the-Ass for the Brain, so use the a Property of our Positional-Notation to make our Life simpler:
\[F^12 = (10 + 6) * 4 * 2\]Then we use the nice Distributive-Feature of our Real-Numbers, but Watch out Boy - don’t forget the Brackets:
\[F^12 = (10*4 + 6*4) * 2\]The Rest we do with Mental-Arithmetic:
\[F^12 = (40 + 24) * 2\]We all know that $4 + 2 = 6$ and $0 + 4 = 4$, therefore:
\[F^12 = 64 * 2\]We all know that $60 * 2 = 120$ and $4 * 2 = 8$, therefore:
\[F^12 = 128\]The very last Step is for more advanced Mathematicians, where we apply Exponentiation with $\frac{1}{12}$ on both Sides of the Equation:
\[(F^12)^{\frac{1}{12}} = (128)^{\frac{1}{12}}\]Finally we shorten the Fraction on the Left and get:
\[F = 128^{\frac{1}{12}} = \sqrt[12]{128}\]The Rest is “Just Doing”, therefore we use a Pocket-Caculater for that, but a least this Time I double-check with the virtual Calculator from My-Mac-Book:
Strange, this means 2:1 against the Table of my Music-Fairy:
But oh Boy, don’t be naive - Since we all know Mens-Rule-Nr-1, the Mistake must be on our Side and because this is a really hard Nut, this Time I definitely need really competent Help. So Tomorrow let’s ask my Mens-Colleague Bert, because Today it has already become quite late:

The next Day I get up very early for Traing with My-Tennis-Teacher. Afterwards I meet three Women, who look like other Versions to three of my known Choir-Colleagues, crazy.
At the Delhi-Palace my dear Asha gives me the Advice to put Focus in my Project on The-Bad-Stuff because the Good-Stuff is done by Others. I don’t know if I understood her correctly, because she sometimes misses the right German Words.
After my Indian-Charu expresses her Concern, that I am doing too many Projects in parallel, I try to reassure her with the Argument that this Work will support my real Goal and in the End Everything will go very quickly.
We also briefly talk about Men in India, who I have already heard Sometimes do not treat their Women very well, Asha’s means, especially the Native Ones.
This reminds me to a funny Conversation about replacing Men with Machines, that I had recently with a cute Blonde off our Choir-Rehersal:
But let’s focus on our Main-Topic: Because of Rule-1 it is clear, that my ϕοκκινγ (Calculating)-Machines have Problems, therefore now I want to do really all manually.
While eating My-Favourite-Indian-Meal I make a few Calculations in my Head and come to the Conclusion that I am able to reduce our Calculation-Problem to $\sqrt{2}$, which after all can be measured with Geometry and is related to the famous Pythagorean-Theorem, the every diligent Lerner knows by Heart:
\[a^2 + b^2 = c^2\]But before I come back on that, I first buy some Equipment in a Stationery-Shop, that I then transport with my Bicycle to the Bus-Station:
At the Bus-Station I have short Discussion with a young Woman about Politics and we came up with the Idea to use the Schimpf-Eck as a Speakers-Corner. But before we can do that, we should definitely ask Mr-Palmer for more Traffic-Mitigation.

Back at Home I finally manage it to read the last E-Mail from my Friend from Bottom-Up, were she first makes a Confession:
Hatte meine Tabelle falsch gelesen.
Of course this must be a White-Lie to make me feel better - such a nice Cupcake. We all know that Rule-1 is Truth-by-Definition, which now reminds me to a Discussion about 1:N-Relations, I had this Afternoon mit my dear Fellow-Occupant.
Then I read further and get to know, that My-Female-Choir-Friend now also did a Verification with her Personal-Computer:
Nun habe ich in Excel nachgerechnet:
F = (2^7)^(1/12) = 1,498307076877
Well, of course we know that there are old Versions of Excel that produced wrong Results and oh Boy, we all remember the really nasty Pentium-FDIV-Bug from 1994 - But what is the Likelihood, that my Friend is really affected by those Threats?
And BTW, since serveral Years I get more and more the Impression that our Development is going into the wrong Direction, namely from The-Better to The-Worse. A good Example is this 20-Year old and still comfortable Running-Shoe, as seen Today in the early Evening:
But Safety-First, so let’s nevertheless do my planned Measurement. Although my new Baby and I have been really careful, the Operation still gets a bit messy - Obviously we need more physical Training:
But probably good enough, so now we can do Everything with Manual-Operation and without the Help of such silly Machines - So back to our last Equation:
\[F = 128^{\frac{1}{12}}\]So first let’s apply on both Sides the Exponentiation an Exponent of Two:
\[F^2 = {128^{\frac{1}{12}}}^2\]An Exponentiation-Function is defined by its Base and the Parameter of the Function is called the Exponent and as all good Mathematicians already know, our Exponentiation with Exponent 2 can be replaced by a Multiplication with 2 in the Exponent:
\[F^2 = 128^{\frac{1}{12} * 2} = 128^{\frac{1 * 2}{12}} = 128^{\frac{2}{12}}\]Now we can simplify the Fraction in the Exponent by a Division by the Greatest-Common-Divisor:
\[F^2 = 128^{\frac{2}{12}} = 128^{\frac{\frac{2}{2}}{\frac{12}{2}}} = 128^{\frac{1}{6}}\]Ok cool, now we eliminate the Exponent on the left Side by Exponentiation with $\frac{1}{2}$:
\[F^{2*\frac{1}{2}} = 128^{\frac{1}{6} * \frac{1}{2}}\]Oehm, this somehow looks familiar, but thank Good, as every good Informatic-Student already knows by Heart, we fortunately can rewrite the Binary-Number 128 as Follows:
\[F = 128^\frac{1}{12} = (2 * 2 * 2 * 2 * 2 * 2 * 2)^\frac{1}{12} = ({2^7})^\frac{1}{12}\]With the already successfully applied Mechanism, we further simplify that:
\[F = ({2^7})^\frac{1}{12} = 2^{7*\frac{1}{12}} = 2^{\frac{7}{12}}\]Oehm …

What the Φοκκ, obviously I made a Mistake in the Indian-Restaurant, because I cannot reduce the Term $2^{\frac{7}{12}}$ to $\sqrt{2}$, sorry my Bad. But no Problem, because all good Mathematicians know, we can use Newton’s–Method for getting an Approximation for the Root-Function.
Ohm, how is the simple Formuala expressed in LaTeX? As already mentioned, my Skills are a bit rusty here and there, but thanks God I have My-Good-Old-Latex-Book:
Here a Good-Man with Patience is able find the TeX-Symbols, that are required for the Translation to the beautiful Mathematics-Symbols:
\[x_{n + 1} = x_n - \frac{f(x_n)}{f'(x_n)}\]Because it is already late, I ask Chat-Gpt to do the Work for me, but without applying the “Potenz-Regel”:
def zwölfte_wurzel_berechnen(zahl, genauigkeit=1e-6, max_iterationen=100):
# Initialisiere den Schätzwert mit der Hälfte der Zahl
schätzwert = zahl / 2.0
for i in range(max_iterationen):
# Verwende die Newton-Raphson-Formel, um den nächsten Schätzwert zu berechnen
nächster_schätzwert = (11 * schätzwert**12 + zahl) / (12 * schätzwert**11)
# Überprüfe, ob die gewünschte Genauigkeit erreicht wurde
if abs(nächster_schätzwert - schätzwert) < genauigkeit:
return nächster_schätzwert
schätzwert = nächster_schätzwert
# Falls die gewünschte Genauigkeit nicht erreicht wurde, gebe den letzten Schätzwert aus
return schätzwert
# Eingabe der Zahl, deren 12. Wurzel berechnet werden soll
zahl = float(input("Bitte geben Sie eine Zahl ein: "))
# Berechnung der 12. Wurzel
ergebnis = zwölfte_wurzel_berechnen(zahl)
# Ausgabe des Ergebnisses
print(f"Die 12. Wurzel von {zahl} ist etwa {ergebnis}")
Then I run the Program and thank God, finally the AI and the Interpreter of Python come (at least almost …) to the same Result as my My-Female-Choir-Friend:

Topics: Zero-Wave-Theory
I meet my Python-Neighbour again, who comes from India and studied Theoretical-Physics. I ask him about the Paradox, that I recently discussed [0] with My-Professor-Friend.
Two identical Lasers with 180 Degree Phase-Shift in Theory eliminate each other and the resulting Energy is Zero. My Neighbour agrees, after he briefly calculated the Following in his Head:
\[e^{x} * e^{-x} = e^{x - x} = e^{0} = 1\]After I give Consideration to the Fact that this would violate the Conservation-of-Energy, he suggest to invent a New-Thing, that in my new Zero-Wave-Theory I call now Zero-Wave or Zero-Particle. Perhaps it can’t be measured, but at least it is able to carry the missing Energy and therefore reconciles Theory with Reality again.
I definitely should ask our local Theory-Expert Professor-Hugo-Reinhard (again), who is said to let only The-Best come through.
Perhaps this Idea is good enough for him and we can win together yet another important Nobel-Prize for Germany, like it e.g. recently has been achieved by Klaus_Ferdinand_Hasselman.

After our Waste-Disposal-Adventure I come up with the Idea of programming a new Quiz-App about the German Waste-Deposit-System, especially regarding the Deposit-Bottles.
The Framework for Apps is based on so called Dings-Objects, which are already available since I introduced the Dings-Sip-Toggle. And for our new Baby I will use exactly the same basic Mechanisms.
Besides that, I take over the proven Design of my good-old Vogelquiz and also reuse some of its Media-Files.
Nevertheless, it took me a whole 5 Days of hard Work for being able to now proudly present the second App in the Dings-System, Ta-Da:

\[Answer = \mathrm{Bauuuspaaarvertrag!}\]And besides other interesting Stuff that was the Topic of a Meeting with my Banker-Friend, who is also am Member of our Doppel-Kopf-Crew. He explained me the Concept of this Bauspar-Vertrag with a simple Example:
Let’s assume I want to buy a Tiny-House for 100.000 Euro and can save for this Goal 10.000 Euro each Year, with simple Mathematics we can calculate my Personal-Wait-Time PWT until I can put the required Money on the Table:
\(PWT = \frac{100.000\;\mathrm{Euro}}{10.000\;\mathrm{\frac{Euro}{Year}}} = 10\;\mathrm{Years}\){#10820:0}
But if I have a Friend, who wants to do the same Thing, we can join our Efforts and pool the Money: After 5 Years we have together 100.000 Euro and the frist one can buy his House:
\(10.000\;\frac{\mathrm{Euro}}{\mathrm{Year * Friend}} * 5\;\mathrm{Years} * 2\;\mathrm{Friends}\) \(= 100.000\;\mathrm{Euro}\)
After another 5 Years also the second one gets his House. So interstingly by this “Financial-Trick” compared to my Personal-Wait-Time (0) the Average-Wait-Time (1) has been reduced from 10 Years to 7,5 Years:
\(AWT = \frac{5 + 10\;\mathrm{Years}}{2} = 7,5\;\mathrm{Years}\){#10821:1}
In Order to see, how this Concept scales, I write a small Python-Program that does the Calculation from 1 to 4 Friends:
# Define Constants
COSTS_PER_HOUSE = 100000 # We can buy a House for 100.000 Coins
MONEY_PER_YEAR = 10000 # Every Friend can save 10.000 Coins each Year
MAXIMUM_YEAR_COUNT = 10 # In 10 Years all Houses are built
MAXIMUM_FRIEND_COUNT = 4 # Maximum Number of Friends that pool the Money
# Calculate the Sum of Years to buy all Houses
def Calculate_Wait_Time_Sum(Friends_Count):
Wait_Time_Sum = 0
Saved_Money = 0
Houses = 0
# Let's see, what we can build in 10 Years
for Year in range(1, MAXIMUM_YEAR_COUNT + 1):
# Calculate the saved Money per Year
Saved_Money += Friends_Count * MONEY_PER_YEAR
# Buy Houses with the saved Money
while Saved_Money >= COSTS_PER_HOUSE:
Houses += 1
Saved_Money -= COSTS_PER_HOUSE
Wait_Time_Sum += Year
print(f" House %2d baught after %2d Years" % (Houses, Year))
return Wait_Time_Sum
# Print the Results for the different Friend-Counts
def Print_Results():
for Friends_Count in range(1, MAXIMUM_FRIEND_COUNT + 1):
print("============ %2d Friends ============" % Friends_Count)
Wait_Time_Sum = Calculate_Wait_Time_Sum(Friends_Count)
print(" ==> Average Time per House: %4.1f Years" % (Wait_Time_Sum / Friends_Count))
Print_Results()
If you want to try out the Program by your own, copy/paste the upper Code to your favourite Python-Interpreter [0] and play with it, or you just trust me that the Output is as follows:
============ 1 Friends ============
House 1 bought after 10 Years
==> Average Time per House: 10.0 Years
============ 2 Friends ============
House 1 bought after 5 Years
House 2 bought after 10 Years
==> Average Time per House: 7.5 Years
============ 3 Friends ============
House 1 bought after 4 Years
House 2 bought after 7 Years
House 3 bought after 10 Years
==> Average Time per House: 7.0 Years
============ 4 Friends ============
House 1 bought after 3 Years
House 2 bought after 5 Years
House 3 bought after 8 Years
House 4 bought after 10 Years
==> Average Time per House: 6.5 Years
============ 5 Friends ============
House 1 bought after 2 Years
House 2 bought after 4 Years
House 3 bought after 6 Years
House 4 bought after 8 Years
House 5 bought after 10 Years
==> Average Time per House: 6.0 Years
Obviously this Concept works better the more Friends are involved, but when we increase the Number, it turns out that (at least with my simple Program) the average Wait-Time converges asymptotically towards 5,5 Years:
Although I studied Economics myself, up to now the Idea of this Financial-Product was not clear to me, which is really shameful. One Explanation could be the questionable Quality of our Academic-System, the Other that back then I just was not interested in the Topic and therefore forgot it again.

Day-105: Singing & Dings-Day
Blog-Chain-Time 2023.07.16-22:10 in Tübingen
Topics: Dings-Day, Decisions
Up to now I counted the Dings-Days as Day-Number from the Beginning of this Project. But since in the last Weeks it happend more and more often that I did not update the Project publicly for several Days, I decide to change the Procedure and define the Dings-Day as follows:
A Dings-Day is a Day, where something worth mentioning is published for the Dings-Project.
So from now on the Counter is always increased by one, regardless of how long ago the last Publication was made and therefore Today we have Number 105.

Several Days ago I re-started my Singing-Lessions with my New-Singing-Teacher, this Time it is a Woman. Because I told her that I would like to sing at Site, we first covered the Topic Solmization, where the Musical-Notes are assigned to the following eight Syllables:
Do Re Mi Fa Sol La Ti Do
In order to train the different Intervals, I sing the Major-Scale from the Root “Do” to some Tone and then directly back to the Root-Tone again.
In another Exercise we try to get more Over-Tones into my Voice. First I sing an “U”, then an “Ü” and finally an “I”. For the latter I notice a Ringing in my Head.
The main Reason is that the Nasal-Cavity is also a Resonance-Body that can be set into Vibration and then creates the Over-Tones. Here as an Example the Frequency-Spectrum of the Tone “U” and the Tone “Ü”:

Blog-Chain-Time 2023.07.07-14:01 in Tübingen
Topics: TeX, Dings-Tool, History
For my last Blog-Entry I introduced into the Dings-Project the Markup-Language TeX, which allows to render especially Mathematical-Symbols in a very beatiful Way.
TeX has been invented between the 1970th and 80th by the Computer-Legend Donald_Knuth and then it was used in the early 80th by Leslie_Lamport to implement his Lamport-TeX or shortly LaTeX. The latter is the most widespread today and also I have used it extensively e.g. for my Studien-Arbeit in 1995/96:
Here is a short TeX Code-Fragment for an Equation, …
$$ H = \sqrt[12]{2} \approx 1,0595 $$
… which is then rendered as:
\[H = \sqrt[12]{2} \approx 1,0595\]A single “$” starts and ends the Math-Mode for TeX and a double “$$” is used for centered unlabled Math-Equations. Fortunately the Pandoc-Tool allows us to use these Formulas also in Markdown-Files.
From the different Pandoc-Options for translating TeX into Html I use the --mathml Option that, as the Name indicates, produces MathMl as Output.
The upper Example is translated then into the following Mathematical-Markup-Language:
<math display="block" xmlns="http://www.w3.org/1998/Math/MathML">
<semantics>
<mrow>
<mi>H</mi><mo>=</mo>
<mroot>
<mn>2</mn>
<mn>12</mn>
</mroot>
<mo>=</mo>
<mn>1</mn><mo>,</mo><mn>0595</mn>
</mrow>
<annotation encoding="application/x-tex"> H = \sqrt[12]{2} = 1,0595 </annotation>
</semantics>
</math>
As we already saw, the rendered Result already looks quite nice, but unfurtunately there is no Support for Labeling and Referencing the Equations. Therefore I extend the Dings-Tool once more and introduce a new Syntax for appending an Anchor and Label:
$$ TeX-Expression $${#ANCHOR:LABEL}
For a nice Formatting I use a Html-Table with three Columns, putting the Equation in the middle and the Anchor to the right. I also add new Css-Classes, like “TeX-Table” or “TeX-Tr” to the Dings-Css-File.
The following Example …
$$ H = \sqrt[12]{2} \approx 1,0595 $${#10480:0}
… is then translated into this Html-Code, …
<table class="TeX-Table">
<tr class="TeX-Tr">
<td class="TeX-Td-Left">
<a id="10480"/>
</td>
<td class="TeX-Td-Equation">
<math display="block" xmlns="http://www.w3.org/1998/Math/MathML"><semantics><mrow><mi>H</mi><mo>=</mo><mroot><mn>2</mn><mn>12</mn></mroot><mo>≈</mo><mn>1</mn><mo>,</mo><mn>0595</mn></mrow><annotation encoding="application/x-tex"> H = \sqrt[12]{2} \approx 1,0595 </annotation></semantics></math>
<td class="TeX-Td-Right">(0)</td>
</tr>
</table>
… that is finally rendered as:
\(H = \sqrt[12]{2} \approx 1,0595\){#10480:0}
Now that the All-Dings-Project is prepared for professional scientific Work, I am very excited about interesting Things that can still be explored.
Day-101: Heimat-Programm & Pythagorean-Comma (again)
Blog-Chain-Time 2023.07.04-23:00 in Tübingen
Topics: Music, Mathematics, Pythagorean-Comma
Because after on our Journey to Freiburg, I was not 100% sure, if my Thoughts about the Pythagorean-Comma were correct, I want to try a Mathematics-Proof now.
According to Wikipedia [0] the Pythagorean-Comma is 23,46 Cent and in the Equal-Temperament one Cent is defined as one hundredth of a Half-Tone.
Since in this System one Half-Tone is exactly one twelfth of an Octave [1], we have to apply to be Base-Frequency BF twelve Times the Multiplication of the Frequency-Ratio of H in order to reach the Octave O:
\[BF * H * H * ... * H * H = O\]Because we choose $Base$-$Frequency=1$ and we already know that the Frequency-Ratio of the Octave is 2:1 or simply 2, we can write this as:
\[H * H * ... * H * H = 2\]Using the Exponentiation we can formulate this also much shorter as:
\[H^12 = 2\]In order to calculate H, we have to apply Exponentiation with $\frac{1}{12}$ on both Sides:
\[(H^{12})^{\frac{1}{12}} = 2^{\frac{1}{12}}\]After shortening the Fraction $12*\frac{1}{12} = 1$ and replacing $2^{\frac{1}{12}}$ with the more common Root-Writing $\sqrt[12]{2}$, we get the following Frequency-Ratio for our Half-Tone:
\[H = \sqrt[12]{2} \approx 1,0595\]As mentioned at the Beginning, according to Wikipedia the Pythagorean-Comma is 23,46 Cent and in the Equal-Temperament one Cent is defined as one hundredth of a Half-Tone, so one could naively assume that we now can calculate Comma-Expected CE as:
\[CE = 23,46 * \frac{1}{100} * H\]Unfortunately it is not such simple, because in our Case we don’t have a linear System. Therefore the Calculation of the Frequence-Ratio for the Half-Tone was the wrong way, sorry by bad. Instead the Frequency-Ratio FR of CT Cents can be calculated [2] with:
\[FR = 2^{\frac{CT}{1200\, Cent}}\]The Reason for the 1200 Cent is the Octave again, that is exactly 12 Have-Tones, or $12 * 100\, Cent = 1200\, Cent$, so $2^{\frac{1200\, Cent}{1200\, Cent}} = 2^1 = 2$, which is - as we already know - the Frequency-Ratio 2:1 of our Ocatave.
So now let’s calculate the Frequency-Ratio for the Pythagorean-Comma with 23,46 Cent:
\(CE = 2^{\frac{23,46\, Cent}{1200\, Cent}} \approx 1,0136\){#10141:1}
If we look at our Results for the Target-Frequencies of 12 Fiths ($1,5^{12}$) and 7 Octaves ($2^7$), our self-calculated Pythagorean-Comma CC can be determinded by:
\(CC = \frac{1,5^{12}}{2^{7}} = \frac{129,75}{128,00} \approx 1,0136\){#10142:2}
Since (1) and (2) result in the same Value, my Calculation seems to be correct and even more Digits behind the Comma look also quite promising:
But I still don’t have the Feeling to really have understood this Music-System completely, so probably it takes a little bit more Time until I can say “q. e. d.” with enough Confidence.

Day-97: Embedding Dings-Files
Blog-Chain-Time 2023.06.30-21:31 in Tübingen
Topics: Rendering-Process, Dings-Tool
Today I upgrade the Rendering-Process of the Dings-Tool by adding Support for embedding Dings-Files in Markdown-Files. For the Time being I use the same Syntax as Markdown does for Images:
When the Dings-Tool generates an Html-Page, it replaces this Text with appropiate Html-Code. For Example the Markdown-Code …
… is converted into the following Html-Code, …
<figure>
<a href="400000034.html">
<img src="400000034.jpg" alt="Updated Rendering Process" style="100%;"/>
</a>
<figcaption>
<a href="400000034.html">Updated Rendering Process</a>
</figcaption>
</figure>
… which then produces this rendered Output:
The nice Thing is that now you can click on the Image or the Caption for navigating to the original Dings-File. At the Moment this works for Jpeg-Image-Files, Mp3-Sound-Files and Mp4-Video-Files.
Day-91: Pythagorean-Comma
Blog-Chain-Time 2023.06.24-12:30 on my Way to Freiburg
Topics: Pythagorean-Comma
While I am driving with my Choir-Colleages for our Performance to Freiburg, I use the Time to investigate the Pythagorean-Comma, that describes a Problem of our Music-System:
If we go up 12 Fiths in the Musical-Scale, we hit the same Note as if we go up 7 Octaves.
But when we add the Frequency-Intervals, we come to a slightly different Result. For an Octave the Frequency doubles and for a Fifth the Frequency is multiplied by 1,5.
For calculating the Result, I write a small Python-Program, …
def Calc_Frequency(Interval, Factor, Count):
Frequency = 1
for Step in range(0, Count + 1):
print(f"{Step:2d} {Interval}: {Frequency:6.2f}")
Frequency = Frequency * Factor
Calc_Frequency("Fifhs ", 1.5, 12)
Calc_Frequency("Octaves", 2, 7)
… that leads to the following Output:
0 Fifhs : 1.00
1 Fifhs : 1.50
2 Fifhs : 2.25
3 Fifhs : 3.38
4 Fifhs : 5.06
5 Fifhs : 7.59
6 Fifhs : 11.39
7 Fifhs : 17.09
8 Fifhs : 25.63
9 Fifhs : 38.44
10 Fifhs : 57.67
11 Fifhs : 86.50
12 Fifhs : 129.75
0 Octaves: 1.00
1 Octaves: 2.00
2 Octaves: 4.00
3 Octaves: 8.00
4 Octaves: 16.00
5 Octaves: 32.00
6 Octaves: 64.00
7 Octaves: 128.00
Of course we can calculate the same with simple Mathematics:
$1,5^{12} - r2^7 = 129,75 - 128,00 = 1,75$
But to be honest, I’m not 100% clear on the whole Problem yet, so a little more Research is probably required.
Day-76: Responsive Web-Design
Blog-Chain-Time 2023.06.09-23:58 in Tübingen
Topics: Web-Design, Favicon
Finally I added the Dings-Favicon that will be shown as Web-Site Logo in many Web-Browsers.
Blog-Chain-Time 2023.06.09-21:32 in Tübingen
Topics: Web-Design, Java-Script, Css, Html, Cookie
I spent the last Days working on the Web-Design of the Dings-Html-Pages. Because my Goal is to use as much of the Screen-Real-Estate as possible, I have to apply some Techniques from Responsive-Web-Design:
I implement a Side-Bar for the Navigation within one Web-Page and a Top-Bar for Naviation within the whole Web-Site.
Initially the Side-Bar should show the Table-Of-Contents of the displayed Page, which I automatically extract from the Markdown-File with a new Sub-Command of the Dings-Tool.
For clean Reading I also want to be able to dynamically disable the Side-Bar. Because this Setting should be valid for the whole Web-Session and should not change when moving to a different Page, I use a Cookie to save the Selection-State.
In order to get the maximum Screen-Size for Reading I also make the Top-Bar disappear, when the User scrolls down.
For Example to dynamically build all this for the Dings-File 23.md, I simply use the new Sub-Command of the Dings-Tool:
$ Dings-Tool Html Generate 23.md -o 23.html
The first Step of the Build-Process extracts the Side-Bar-Content (TOC) from the Markdown-File:
Then the new Side-Bar-Content is integrated into the Dings-Html-Template, which produces the Pandoc-Html-Template:
Finally the Pandoc-Tool is called with the new Pandoc-Html-Template and the original Markdown-File, which then generates the completed Html-File:
To realize all this was a lot of Trial-and-Error Work, again it was more Hacking than Programming, but in the End I am halfway satisfied with the Result:
Day-70: Hash-Functions
Blog-Chain-Time 2023.06.03-23:02 in Tübingen
Topics: Hash-Function, Performance, Test
For the Measurement of the Performance of the different Hash-Functions I write a small Python-Program that runs each Hash-Algorithm 32 Times on 1024 KiB of random Input-Data, so in total 512 Mebi-Bytes or 512 Mega-Bytes plus 48.576 Bytes are processed.
Then I run this Program on four different Platforms:
- On Mac-OS-12.6.2 native on My-Mac-Book
- On Ubuntu-22.04 under Docker on My-Mac-Book
- On Ubuntu-22.04 under WSL on My-Surface-Book
- On Ubuntu-22.04 under Docker on My-Surface-Book
Python does not implement the Hash-Functions by its own, but instead uses Standard-Libraries for that. For the latter three Setups under Ubuntu-Linux the Open-SSL Library is used, …
root:~# openssl version
OpenSSL 3.0.2 15 Mar 2022 (Library: OpenSSL 3.0.2 15 Mar 2022
… and Mac-OS helps itself with the Libre-SSL:
$ openssl version
LibreSSL 2.8.3
For Completeness I also implemented the Digit-Sum in Python …
class Csum_Class:
def hexdigest(Self, Max_Byte = 0):
Hex_String = hex(Self.Hash_Value)
if Max_Byte == 0:
return Hex_String
else:
return Hex_String[2:Max_Byte * 2]
class Add_Py(Csum_Class):
def __init__(Self, Data):
Data_Size = Bm.Byte(len(Data))
Self.Hash_Value = 0
for Byte_Nr in range(0, int(Data_Size.to_Byte())):
Self.Hash_Value += int(Data[Byte_Nr])
… and in C that can be called from my Python-Program:
import Dings_Lib_C
class Add_C(Csum_Class):
def __init__(Self, Data):
Self.Hash_Value = Dings_Lib_C.Adder_Csum(bytearray(Data))
static PyObject* Adder_Csum(PyObject* self, PyObject *args)
{
unsigned long Csum = 0;
unsigned char *Buf;
Py_buffer Buffer;
PyObject *Bytes;
int i;
if (!PyArg_ParseTuple(args, "O|b", &Bytes))
return NULL;
if (PyObject_GetBuffer(Bytes, &Buffer, PyBUF_WRITABLE) < 0)
return NULL;
Buf = Buffer.buf;
for(i=0; i < Buffer.len; i++) {
Csum += Buf[i];
}
PyBuffer_Release(&Buffer);
return Py_BuildValue("l", Csum);
}
To make a nice Presentation of the Experiment I use the Matplotlib, that allows to render my Data as a Bar-Chart. As Metric for the Performance-Data I show how much Mebi-Bytes per Second each Hash-Algorithm can process.
From the resulting Diagram, I find five Observations interesting respectively surprising:
- My Python-Adder-Function is terribly slow.
- The C-Adder-Function is slow on Ubuntu.
- In most Cases the Mac-Book seems to be much faster that my Surface-Book.
- SHA-384 and SHA-512 run much faster on Mac-Book under Ubuntu.
- For MD5 we don’t see a Speedup on Mac-Book.
Because there are a lot of Variables and Layers, it is hard to prove the real Reasons for these Observations, but nevertheless I would like to make some Hypothesis:
The interpreted Python is just much slower than compiled C, although I would not have expected such a huge Impact.
On my Surface-Book probably the CPU and on Mac-Book the GPU is used, which is optimized for Hash-Generation. One Indication for this Claim is Observation 5, where I assume that the MD5-Algorithm runs on the CPU for all Platforms.
For Observation 3 my Hpyothesis is that Open-SSL provides GPU-Support, whereas Libre-SSL uses the CPU.
Besides the really bad Pyhton-Performance at least one last Mystery remains: Why is the C-Adder-Function so fast on the native Mac-Book?
Blog-Chain-Time 2023.06.03-23:02 in Tübingen
Topics: Hash-Functions
The last Days I have dealt with the Topic Hash-Functions: In Informatics you find them everywhere, for Example Git uses SHA-1 or Bitcoin utilizes SHA-256, which is one Member of the SHA-2-Family.
The Algorithms mentioned have been developed by the NSA and standardized by the NIST. Both Institutions are located in the USA.
Hash-Functions are used to reduce big Numbers to small Ones. A simple Secimen for an Hash-Algorithm is the Digit-Sum, where for Example the Number 4711 is mapped to the Number 13.
A Problem of Hash-Sums are the so called Hash-Collisions: Since the Input-Set is bigger than the Output-Set it is unavoidable that there are two Input-Numbers that map to the same Output-Number.
Here an Example for our Digit-Sum, where the Numbers 4711 and 1003 lead both to the Number 13:
Digit-Sum(4711) = 13 (4 + 7 + 1 + 1)
Digit-Sum(1003) = 13 (1 + 0 + 0 + 1)
One Quality of a Hash-Algorithm is its Collision-Resistence, which is the Likelihood that this happens.
Day-67: Serialization
Blog-Chain-Time 2023.05.31-23:02 in Tübingen
Topics: Serialization, Test
Since some Days I am pondering about how to store my own Meta-Data and my prefered Solution for that is Json. In order to convert hierarchical Data-Structures into a linear Representation, in Informatics a Process called Serialization is used.
It would be perfect if I could directly save and load my Python-Classes with such a Process. To explore the Possibilites, I write a small Test-Programm, where I use Dictionaries, Lists and Classes:
import json as Json
class Object_Json_Encoder_Class(Json.JSONEncoder):
def default(Self, o):
return o.__dict__
class Point_Class():
def __init__(Self, x, y):
Self.x = int(x)
Self.y = int(y)
def Print_Dict(Dict):
for Key in Dict:
Value = Dict[Key]
Type = str(type(Value))
print(f"Key={Key}")
print(f" Type='{Type}'")
print(f" Value={Value}")
Point = Point_Class(1,2)
Test_Dict_Code = {
"My_Integer": 4711,
"My_String": "Test",
"My_Point": Point,
"My_Point_List": [ Point, Point ],
"My_String_List": ["aa", "bb", "cc"]
}
Test_Json_String = Json.dumps(Test_Dict_Code, cls=Object_Json_Encoder_Class)
Test_Dict_Json = Json.loads(Test_Json_String)
Print_Dict(Test_Dict)
Print_Dict(Test_Dict_Json)
After running the Thing, I see the following Output:
Key=My_Integer
Type='<class 'int'>'
Value=4711
Key=My_String
Type='<class 'str'>'
Value=Test
Key=My_Point
Type='<class '__main__.Point_Class'>'
Value=<__main__.Point_Class object at 0x1031c6990>
Key=My_Point_List
Type='<class 'list'>'
Value=[<__main__.Point_Class object at 0x1031c6990>, <__main__.Point_Class object at 0x1031c6990>]
Key=My_String_List
Type='<class 'list'>'
Value=['aa', 'bb', 'cc']
Key=My_Integer
Type='<class 'int'>'
Value=4711
Key=My_String
Type='<class 'str'>'
Value=Test
Key=My_Point
Type='<class 'dict'>'
Value={'x': 1, 'y': 2}
Key=My_Point_List
Type='<class 'list'>'
Value=[{'x': 1, 'y': 2}, {'x': 1, 'y': 2}]
Key=My_String_List
Type='<class 'list'>'
Value=['aa', 'bb', 'cc']
Obviously some Information is lost in the Transformation-Process: The original Dictionary still knows the correct “Point_Class” Data-Type, …
Key=My_Point
Type='<class '__main__.Point_Class'>'
Value=<__main__.Point_Class object at 0x1031c6990>
… whereas the Dictionary that has been created from the Json-String claims that the Data-Type is a Dictionary:
Key=My_Point
Type='<class 'dict'>'
Value={'x': 1, 'y': 2}
And that’s not a Wonder, because the Json-String does no longer contain this Information:
{
"My_Integer": 4711,
"My_String": "Test",
"My_Point": {
"x": 1,
"y": 2
},
"My_Point_List": [
{
"x": 1,
"y": 2
},
{
"x": 1,
"y": 2
}
],
"My_String_List": [
"aa",
"bb",
"cc"
]
}

So now let’s switch to Windows, where I first have to create a virtual Environment again (important):
$ python -m venv My-App
$ cd My-App
Then I build the Py-Installer-Spec-File:
~/My-App$ python -m PyInstaller --onefile --name Dings-App ..\..\Dings_App\main.py
Then I add some Lines to the Config-File, that the App-Files and Libraries are included in the EXE-File:

Today I want to run the Dings-App on iOs, therefore I first install the kivy-ios Package:
~/All-Dings$ pip3 install kivy-ios
Then I create a Build-Directory:
~/All-Dings$ mkdir kivy-build
Next I use the Tool-Chain-Command to build required Libraries and Stuff:
~/All-Dings/kivy-build$ toolchain build python3 kivy openssl
After that I have to install the required Python-Modules for my App:
~/All-Dings/kivy-build$ toolchain pip install pygments docutils
Then I create the X-Code Project with the Tool-Chain-Command:
~/All-Dings/kivy-build$ toolchain create Dings_App ~/All-Dings/777/Dings_App/
Note, that for this Step only the required Files should be in the Dings_App Directory, e.g. remove the .buildozer Directory before.
Finally I start X-Code with the Open-Command, …
~/All-Dings/kivy-build$ open dings_app-ios/dings_app.xcodeproj/
… and then run the App on my iPad:

Interestingly the following similar Code …

Spent the whole Day on Coding the Command-Line-Parsing for the Dings-Tool and I am a bit frustrated, that it takes such a long Time for such a relatively easy Task.
Day-38: Dings-Lib Classes
Blog-Chain-Time 2023.05.31-18:43 in Tübingen
Topics: Dings-Lib, Inheritance, Class-Hierarchy
I extend the Code once again and use the Concepts Inheritance from the Object-oriented-Paradigm, both Perl and Python have Support for that.
Three Sub-Classes e.g. Code_To_Markdown are defined for the old Base-Class Code_To_Markdown.
BTW, Class-Hieraries, like all other Trees in the Informatics-System, are normally shown with the Root on Top:
+--------------------+
| |
| Code_To_Markdown |
| |
+---------+----------+
|
+-------------------------+--------------------------+
| | |
v v v
+--------------------+ +--------------------+ +--------------------+
| | | | | |
| Python_To_Markdown | | Perl_To_Markdown | | Css_To_Markdown |
| | | | | |
+--------------------+ +--------------------+ +--------------------+
Here a Code-Snipped from the Perl-Version:
# Convert Python-Code ot Markdown
package Python_To_Markdown;
use base 'Code_To_Markdown';
sub new {
my $Class = shift;
my $Self = $Class->SUPER::new(@_);
$Self->{'Reg_Exp_Heading'} = '^' . '#+' . ' ' . '.*';
$Self->{'Reg_Exp_Comment'} = '^' . '"""' . '\s*';
return $Self;
}
And here the corresponding Python Variant:
# Convert Python-Code ot Markdown
class Python_To_Markdown(Code_To_Markdown):
def __init__(Self):
Self.Reg_Exp_Heading = re.compile('^' + '#+' + ' ' + '.*')
Self.Reg_Exp_Comment = re.compile('^' + '"""' + '\s*')
super().__init__()
I use the Class-Hierarchy for Sharing the Method Process_Line() of the Base-Class that then calls the specific Methods of its Sub-Classes:
def Process_Line(Self, Line, Line_Number):
Line = Line.rstrip()
if Self.State == Self.States.Init:
Self.Handle_State_Init(Line)
elif Self.State == Self.States.Heading:
Self.Handle_State_Heading(Line)
elif Self.State == Self.States.Code:
Self.Handle_State_Code(Line)
elif Self.State == Self.State.Comment:
Self.Handle_State_Comment(Line)
return Self.State
Day-37: Programming-Paradigm
Blog-Chain-Time 2023.04.30-23:21 in Tübingen
Topics: Dings-Lib, Programming-Paradigm, Programming-Class
Today I extended my Dings-Lib with some Code that follows the Object-oriented-Paradigm, both Perl and Python have Support for that.
I defined a new Class Code_To_Markdown together with a Constructor and some Methods like e.g. Process_End().
Here a Code-Snipped from the Perl-Version:
package Code_To_Markdown;
sub new($)
{
my $Class = $_[0];
my $Self = {
'State' => Init,
'Reg_Exp_Heading' => '^' . '#+' . ' ' . '.*',
'Reg_Exp_Comment' => '^' . '"""' . '\s*',
};
bless $Self, $Class;
return $Self;
}
sub Process_End($)
{
my $Self = $_[0];
if ($Self->{State} == Code) {
printf "```\n";
}
}
[8> Snip ]
sub Language_To_Markdown_Test()
{
my $To_Markdown = new Code_To_Markdown();
$To_Markdown->Convert("$Dings_Directory/300010010.py");
}
And here the corresponding Python Variant:
## Class Code-To-Markdown
class Code_To_Markdown:
def __init__(Self):
Self.States = Enum('States', ['Init', 'Heading', 'Comment', 'Code'])
Self.State = Self.States.Init
Self.Reg_Exp_Heading = re.compile('^' + '#+' + ' ' + '.*')
Self.Reg_Exp_Comment = re.compile('^' + '"""' + '\s*')
def Process_End(Self):
if Self.State == Self.States.Code:
print("```")

Day-35: Programming & Privacy
Blog-Chain-Time 2023.04.28-15:10 in Tübingen
Topics: Dings-Lib, Python, Bug, Type-Inference, Sorting, Programming-Study
While completing my Functions for Reading and Printing all my Dings, I notice that my Code does not sort the Number-Files correctly:
✔ ~/All-Dings/111/0 [Master ↑·1|✚ 4…5] 18:20
$ python3 300010010.py
[Snip]

99 "Coincidence"
9999997 "Informatics-Famous-Human"
9999998 "Informatics-Student"
9999999 "Informatics-System"
First I assumed the Problem is in the Python-Sorted-Function and then with the Help of Chat-GPT even wrote my own Quick-Sort-Function:
## Quick-Sort for List of Dictionary
def Quicksort_List_of_Dictionary(List, Key):
Element_Count = len(List)
if Element_Count <= 1:
return List
Pivot = List[Element_Count // 2][Key]
Left = [Element for Element in List if Element[Key] < Pivot]
Middle = [Element for Element in List if Element[Key] == Pivot]
Right = [Element for Element in List if Element[Key] > Pivot]
return Quicksort_List_of_Dictionary(Left, Key) + Middle + Quicksort_List_of_Dictionary(Right, Key)
Unfortunately the Problem was not solved by simply replacing the Sorting-Function. After over one Hour of Debugging I the found the Problem in the following Code:
## Read Data of a Number-File
def Read_Number_File(File_Name):
with open(os.path.join(Dings_Directory, File_Name), 'r') as File:
First_Line = File.readline()
Name = Name_Regex.sub(r'\1', First_Line)
Number = Number_Regex.sub(r'\1', File_Name)
### Define new [Dictionary](/0/250000018.html) for Number-File
Number_File = {}
Number_File['Number'] = Number
Number_File['Name'] = Name.strip()
return Number_File
Besides of my own Ignorance, the Reason for the Bug is located in the Type-Inference-Feature of Python, which automatically concludes that Number_File['Number'] is a String.
The Compare-Operators for Strings use Alphabetic-Order and therefore regarding Sorting the Following is a true Statement:
9300006 < 99 < 9999997
The Bug-Fix for the Problem is to use the Cast-Operator so that Python knows that each Number should be interpreted as Integer-Type:

Topics: Privacy, Todo
While debugging the Python-Problem, my Artist-Friend calls me and we have a long Discussion about my Project. In particular the Fact that currently all Information is public scares my Colleague.
I understand his Problem, but of course this is Nothing new: Big Companies like Google or Facebook already store Loads of Information and most likely create more or less anonymous User-Profiles.
The Difference is that my User-Profiles are public and with all the Connections Everybody can get potential dangerous Information.
Although I normally ask People, if I am allowed to create a Number-File like e.g. for My-Tennis-Win-Friend, there are also implicite Profiles:
For Example after reading my Bus-Driver-Story someone could find in real Life the young Man, who compared the Mood of the People in Tübingen and Reutlingen. Since there are not many Bus-Drivers in Tübingen that are 22 Years old, the Search is probably not very difficult.
Therefore in the worst Case Information of my Project could be harmful.
Because I don’t have a good Answer to that Problem up to now, I put the Topic Privacy to my Todo-List and take it upon myself to be as careful as possible for the Time being.
Blog-Chain-Time 2023.04.28-21:38 in Tübingen
Topics: Programming, Python, Perl, Regular-Expression, Compatibility
Let’s come back to the Topic Programming again: I have now two Implementations of the same Algorithm. In Theory with the same Input the same Output should produced by the Perl- and the Python-Program, so let’s give it a Try:
✔ ~/All-Dings/111/0 [Master ↓·41|✚ 1…4] 21:37
$ perl 300010011.pl > out.perl
✔ ~/All-Dings/111/0 [Master ↓·41|✚ 1…5] 21:37
$ python3 300010010.py > out.python
Then we use the Unix-Diff-Command to ensure that the two Output-Files have the same Content:
✔ ~/All-Dings/111/0 [Master ↓·41|✚ 1…6] 21:37
$ diff out.perl out.python
1,1021c1,2041
< 0 "Michael_Holzheu"
< 1 "Clash of Clans Erster Geburtstag "
< 2 "Clash of Clans: Erster Geburtstag"
[8<Snip>8]
---
> 0 "Michael_Holzheu
> "
> 1 "Clash of Clans Erster Geburtstag
> "
> 2 "Clash of Clans: Erster Geburtstag
[8<Snip>8]
All Lines marked with < belong to out.perl and those with > to out.python. It looks like that the Pyton-Output contains one additional New-Line at the End.
I extract the Dings-Name from a Number-File using Regular-Expressions and BTW, at leasst Chat-GPT claims that the Concepts for those Expressions have been developed in the 1950s by Stephen_Cole_Kleene.
So let’s look first at the Perl Version, …
my $Heading_Regex = qr/^#\s+(.*)$/;
… and then at the Python Variant:
Name_Regex = re.compile(r'^#\s+(.*)$')
Besides of the surrounding Stuff, both Lines are identical and the extracted Regular-Expression is as Follows:
^#\s+(.*)$
Looks like that the Implementations of Regular-Expressions are different in Perl and Python, to prove that I extract the Code into two Test-Files:
✔ ~/All-Dings/Test 23:27
$ cat regex-test.pl
my $Heading_Regex = qr/^#\s+(.*)$/;
my $File_Name = "0.md";
open my $File, '<', $File_Name;
$First_Line = <$File>;
printf("\"%s\"\n", $First_Line);
$First_Line =~ /$Heading_Regex/;
printf("\"%s\"\n", $1);
✔ ~/All-Dings/Test 23:27
$ cat regex-test.py
import re
Name_Regex = re.compile(r'^#\s+(.*)$')
with open("0.md", 'r') as File:
First_Line = File.readline()
print(f'"{First_Line}"')
Name = Name_Regex.sub(r'\1', First_Line)
print(f'"{Name}"')
Then I run both against my 0.md-File:
✔ ~/All-Dings/Test 23:29
$ head -3 0.md
# Michael_Holzheu
<img src="0.jpg" alt="Michael_Holzheu" style="width:256px; height: 256px;"/>
And the Result is the Proof:
✔ ~/All-Dings/Test 23:31
$ perl regex-test.pl > out.perl
✔ ~/All-Dings/Test 23:31
$ python3 regex-test.py > out.python
✔ ~/All-Dings/Test 23:31
$ diff out.perl out.python
3c3,4
< "Michael_Holzheu"
---
> "Michael_Holzheu
> "
So the Perl Regular-Expression seems not to match the New-Line, whereas Python includes it.
A Work-Around for this Compatibility-Problem is to use the Python Strip-Function that removes the trailing White-Space before we apply the Regular-Expression:
✔ ~/All-Dings/Test 23:56
$ diff -Nau regex-test.py regex-test-strip.py
--- regex-test.py 2023-04-28 23:55:20.000000000 +0200

Name = Name_Regex.sub(r'\1', First_Line)
print(f'"{Name}"')
Finally I have to add a Strip-Function also to my Perl-Version:

Day-33: Starting Dings-Library

Topics: Chat-GPT, Graph-Structure
Today I would like to print the Graph-Structure of all my current Things, but because I am lazy, I ask Chat-GPT for Help:
Write a program that prints a graph graphically
Sure, here's an example Python program that reads in a graph represented as an adjacency list and prints out its graphically using the networkx and matplotlib libraries:
import networkx as nx
import matplotlib.pyplot as plt
# Define a function to read in a graph from a file
def read_graph(filename):
# Create an empty dictionary to hold the graph
graph = {}
[...]
Then I install the two required Libraries, …

Day-32: Information-Mapping
Blog-Chain-Time 2023.04.25-14:15 in Tübingen
Topics: Dings, Information-Mapping
Since several Days I think about a good Mechanism, how to share Information between Documents. IMHO, in Principle there are three different Ways to do that:
- Reference Information
- Include Information
- Copy Information
Reference Information
We could create a new Document that uses a Direct-Reference on the above Information, …
# Document about Including Information
Michael_Holzheu wrote that there are [three](/0/23.html#3201) Ways of sharing Information.
… or we could use an Indirect-Reference:
# Document about Including Information
Michael_Holzheu wrote that there are three Ways of sharing Information [[1000]](#1000).
## References
[<a id="1000"/>1000] [About-Dings-Share-Information](/0/23.html#3201)
Include Information
We could build a Mechanism that allows to include Sections 1:1 into other Documents, e.g. with some Include-Statement we could import this Blog-Entry in our new Document. At least for Images this already works for Markdown, where the !-Character is used for the Include-Statement:
# Document about Including Information
Michael_Holzheu wrote the following:
Copy Information
Finally we can of course manually copy the Information:
# Document about Including Information
Michael_Holzheu wrote that there are [three](/0/23.html#3201) Ways of sharing Information:
- Reference Information
- Include Information
- Copy Information
Blog-Chain-Time 2023.04.25-14:15 in Tübingen
Topics: Information-Sharing, Internet, Xanadu, Virtual-Mapping
So, after thinking a little bit about Information-Sharing Theory, let’s have a Look on the History of Internet:
The British Man Tim_Berners-Lee invented HTML that provides Hyper-Links for Referencing Information in the World-Wide-Web.
A Link can be specified as follows:
<a href="https://holzheu.de/">Web-Site from Michael_Holzheu</a>
Like with Markdown, there seems to be no native Mechanism [3211] in HTML to include other HTML-Pages, but interestingly including Pictures is possible:
<img src="0.jpg" alt="Michael_Holzheu"/>
The US Man Ted_Nelson suggested an Alterntive to the Ideas of Tim_Berners-Lee and implemented the Xanadu-System, which is able to include Information in other Documents using so-called Transclusion, where the Data is copied only at Rendering-Time.
The Concept of Transclusion is a very wide-spread Thing that is called Mapping in Virtualization, e.g. the following three Examples immediately come into my Mind:
- Mappings with the MMap-Unix-System-Call
- References in Spread-Sheets
- Include-Files in Programming-Languages
Here a small Diagram that illustrates the Concept of Virtual-Mapping at the Example of two different Virtual-Documents that are constructed out of three “real” Objects:
+---------------------------------------------------------+
| |
| Virtual-1 Real Virtual-2 |
| |
| +-------------------+ +-------------------+ |
| | Object-3 | Object-1 | Object-1 | |
| | | | | |
| | Object-2 | Object-2 | Object-2 | |
| | | | | |
| | Object-1 | Object-3 | Object-3 | |
| +-------------------+ +-------------------+ |
| |
+---------------------------------------------------------+
Advantages of Virtual-Mappings:
- Resource-Consumption: The References require less Ressources than the real Objects
- Consistency: When a real Object is changed, all virtual Objects automatically get the Update
Disadvantages of Virtual-Mappings:
- External-References: When mapping a real Object also all of its External-References have to be somewhere mapped in the Virtual-Document.
- Reference-Relocation: If References have a Local-Name they have to be renamed in the Virtual-Document, this Process is also Sometimes called Rellocation.
- Resource-Consumption: The Resolution of References in the Rendering-Process also takes some Time.
- Consistency: When one Physical-Object is updated and the Meaning changes, the overall Consisteny in the Virtual-Document still have to be ensured somehow.

Day-31: Chat-GPT
Blog-Chain-Time 2023.04.24-15:40 in Tübingen
Topics: Chat-GPT, Perl
I heard that Chat-GPT can also write Program-Code, so let’s try:
Michael: Write perl code for quicksort
Chat-GPT: Sure, here's an implementation of quicksort in Perl:
sub quicksort {
my @arr = @_;
if (@arr <= 1) {
return @arr;
}
my $pivot = $arr[int(@arr/2)];
my @left = grep { $_ < $pivot } @arr;
my @middle = grep { $_ == $pivot } @arr;
my @right = grep { $_ > $pivot } @arr;
return (quicksort(@left), @middle, quicksort(@right));
}
The Code looks good and even an Example-Program is provided, …
✔ ~/All-Dings 15:43
$ tail -4 Quick-Sort.pl
my @my_list = (4, 2, 7, 1, 3, 5, 6);
my @sorted_list = quicksort(@my_list);
print join(", ", @sorted_list), "\n";
… that seems to work:
✔ ~/All-Dings 15:44
$ perl Quick-Sort.pl
1, 2, 3, 4, 5, 6, 7
Day-30: Starting Studies
Blog-Chain-Time 2023.04.23-18:04 in Tübingen
Topics: Brezel-Study, Study
After adding lots of new Concepts again, I started my first Study for this Project.
Day-29: Decision-Problems (again)
Blog-Chain-Time 2023.04.23-02:29 in Tübingen
Topics: Abbreviations, Decisions
Finally I also revert my last Abbreviation-Idea.
Blog-Chain-Time 2023.04.22-20:03 in Tübingen
Topics: Underscore, Hyphen, Decisions
After I already had a bad Feeling with my Yesterday’s Work, I now decided to revert the first Idea of using the Underscore as Word_Separator_Character.
I my new Idea is to use the Underscore for Names like Roxana_Stanciu and the Hyphen for all combinded Things like
First I manually edit the Dings-File and then use the following Script to change all Names:
cat 0.txt | awk '{print $2}' | grep - | while read -r Dings; do if [ "$Dings" != "" ]; then Old_Dings=$(echo $Dings | sed -E 's/-/_/g'); echo "$Old_Dings -> $Dings"; sed -i '' 's/$Old_Dings/$Dings/g' *.md; fi; done
But to remember the History, I would like to keep my two Blog-Files unchanged:
✔ ~/All-Dings/111/0 [Master|✚ 3] 20:11
$ git checkout 23.md
Updated 0 paths from the index
✔ ~/All-Dings/111/0 [Master|✚ 3] 20:11
$ git checkout 21.md
Updated 0 paths from the index
Day-28: Decision-Problems
Blog-Chain-Time 2023.04.21-18:00 in Tübingen
Topics: Underscore, Hyphen, Decisions
After I worked a lot on the Concepts Relation and Function, I came back to Informatics again. Then I realized that my current Naming_Convention to use Hyphens as Word_Separator_Character is suboptimal for (Programming_Languages)[9010000.md]. Therefore I decided with a heavy Heart to exchange all the --Characters with their _-Counter_Parts.
Blog-Chain-Time 2023.04.21-18:00 in Tübingen
Topics: Abbreviation, Decisions
Then I introduce for each Discipline an Abbreviation, for Example Math_System instead of Mathematics_System, but TBH I am not really sure if that Decision is a good Idea.

README.mdis used as Landing-Page for the Git-Repository, I create a Soft-Link fromREADME.mdto the Repository-File. - Naming-File: For each Repository we have a Naming-File with the Name
REPOSITORY-NUMBER.txt, which describes the Mapping between Numbers and Names.
So for our 0-Repository it now looks like the Following:
✔ ~/All-Dings/111/0 [Master ↓·4|✚ 2…1] 15:49
$ ls -l 0.*

After I organized the Naming-File in the 0-Repository I think about where to store the Things that are required by all other Repositories.
The Best I can think of now is to move all to the Rendering-Repository:
## 111 About-Rendering-Repository
1000001.md Blog-Chain-Time
300000008.md All-Dings-Abbreviation-Character
300000007.md All-Dings-System
300000006.md All-Dings-Landing-Page
300000004.make All-Dings-HTML-Make-File

23.md About-All-Dings
300001000.make Rendering-Makefile
300000007.md All-Dings-Rendering-Repository
17.md All-Things
111.md About-Rendering-Repository
But now the next Problem arises: If I do this, I would change the Meaning of the Rendering-Repository and consequently I should rename it to All-Dings.
Somehow I don’t like this, because my Idea up to now was that the Numbers are made for Eternaty and Changing the Meaning of a Number-File would conceptually be the same as Changing its Number.
So until I am more clear on this Question I leave the All-Dings-Things in the 0-Repository and hope that good Ideas arrive soon.

While showing my Buddy the current Naming-File, we stumbled across the Word Waiter, which triggered a short Discussion about Gender-Separation in the All-Dings Project. My current Approach for this this Problem is to use as neutral as possible Terms for all my Things.

Blog-Chain-Time 2023.04.13-12:30 in Tübingen
Topics: Programming
After the Tennis-Training I decided to use this Day for Programming. To speparate Things, I create for this a new Programming-Repository with the Number 250000000.
I would like to re-write the lost Perl-Programm, and use the Opportunity to compare the two Programming-Languages Perl and Python.
For local Work on my Mac-Book-Pro I first install the Python-3-Package:
✘-1 ~/All-Dings/1000001000 [Master ↓·1|✚ 1] 12:34
$ brew install python
Then I create two new Number-Files in the Programming-Repository:
- Perl-Basics: 250010000.pl
- Python-Basics: 250020000.py
To separate Things even more, I create a new Blog-File for this Project:
- Programming-Basics: 250000001.md
The first Thing when learning a Programming-Language is the Hello-World-Program, which should print the Message Hello World! to the Screen.
But before we do that, we have to learn two other Concepts, namely Program-Comments and Program-Functions.
At least the first one is quite simple, …
18:06
$ cat 250000004.md
# Program-Comment
A Program-Comment is used be a [Programm-Writer](/0/202000006.html) to explain his [Program](/0/250000005.html).
… but when I wanted to describe, what a Program-Function exectly is, I went from a Hundred to a Thousand:
# Program-Function
A Program-Function uses a [List](/0/60008.html) of [Program-Statements](/0/250000007.html) to transform [Program-Parameters](/0/250000009.html) into [Program-Output](/0/250000014.html).
# Program
A Program is the [Implementation](/0/600057.html) of an [Algorithm](/0/250000006.html).
# Algorithm
An Algorithm is a [Description](/0/600056.html) for as [Solution](/0/600024.html) of a given [Problem](/0/600029.html).
# Program-Statement
A Program-Statement is the smallest non devisable [Element](/0/700006.html) of a [Programming-Language](/0/9010000.html)
# Program-Variable
A Program-Variable has a [Name](/0/60048.html) and contains [Data](/0/60001.html).
# Program-Parameter
A Program-Parameter is used to pass [Data](/0/60001.html) from the [Program-Caller](/0/250000010.html) to the [Program-Callee](/0/250000011.html) by creating a new [Name-Binding](/0/60050.html) that gives the [Program-Caller](/0/250000010.html) some kind of [Access](/0/60049.html) to the Data.
# Program-Caller
The Program-Caller gives [Program-Control](/0/250000012.html) to a [Program-Callee](/0/250000011.html).
# Program-Callee
A Program-Callee receives [Program-Control](/0/250000012.html) from a [Program-Caller](/0/250000010.html).
# Program-Control
Program-Control defines which Part of a [Program](/0/250000005.html) executes [Program-Statements](/0/250000007.html) at a given Time.
# Program-Executer
A Program-Executer processes the [Program-Statements](/0/250000007.html) of a [Program](/0/250000005.html) according to the [Specification](/0/600060.html) of the [Programming-Language](/0/9010000.html).
# Program-Output
Program-Output is [Data](/0/60001.html) that is created by a [Program](/0/250000005.html).
# Program-Input
Program-Input is [Data](/0/60001.html) that is transfered to a [Program](/0/250000005.html)
So a Program-Function uses a List of Program-Statements to transform Program-Parameters into Program-Output.
Hmm, sounds more like the Definition of a Program, so let’s check, what I have written for that Thing:
✔ ~/All-Dings/250000000 [main|✔]
18:16
$ cat 250000005.md
# Program
A Program is the [Implementation](/0/600057.html) of an [Algorithm](/0/250000006.html).
Well that is of course also true for a Function …
Blog-Chain-Time 2023.04.13-12:09:48 in Tübingen
On my Smoking-Round I came to a Conclusion for the Program-vs-Function-Question: Every Function is a Program, but at a different Nesting-Level. It is somehow like with a Russian-Matrjoschka where one Thing contains the next one.
But our Situation is a bit more complex that with the Russian Lady, who always has a 1:1 Relation between the different Container-Ladies.
So maybe a better Analogy would be a the Human-Body, that contains many Organs, that contain many Cells and so on.
So let’s create some Ascii-Art [0] and draw first the Tree-Diagram that shows a small Part of our Computer-Matrjoschka:
┌──────────────┐
│ Program │
└──────┬───────┘
│
┌──────────────────┼──────────────────┐
│ │ │
▼ ▼ ▼
┌───────────────┐ ┌───────────────┐ ┌───────────────┐
│ Function-A │ │ Function-B │ │ Function-C │
└───────────────┘ └───────────────┘ └───────────────┘
And finally look at the same Thing using a Set-Diagram:
┌──────────────────────────────────────────────────────┐
│ Process │
│ ┌───────────────┐ ┌───────────────┐ ┌──────────────┐ │
│ │ Function-A │ │ Function-B │ │ Function-C │ │
│ └───────────────┘ └───────────────┘ └──────────────┘ │

Day-19: Consistency
Topics: Programming
Blog-Chain-Time 2023.04.12-17:23 in Tübingen, Yesterday I was thinking on the Problem, how to reference Information in my Documents.
References have two Elements, namely the Anchor that marks the Location of an Information and a Link from another Document that adressess that Anchor.
In Markdown there is the Concept of local Links that are automatically created [0] for each Heading. Unfotunately it looks like that there is no common Standard, how the Anchors are created.
Let’s use the following Heading as Example:
#### Blog-Chain-Time 2023.04.12-14:46 in Tübingen
I found a Web-Page that automaticall creates the following Link for this Heading:
[Blog-Chain-Time 2023.04.12-15:28 in Tübingen](#blog-chain-time-20230412-15-28-in-t-bingen)
So it creates out of the Heading-String Blog-Chain-Time 2023.04.12-15:28 in Tübingen the Anchor blog-chain-time-20230412-15-28-in-t-bingen.
Unfortuately the Git-Hub Markdown assumes a different Anochor for the Heading, namely blog-chain-time-20230412-1446-in-tübingen, and therefore the generated Link does not work.
I this Project for Addressing of Number-Files we already use its Number, so my new Idea is to also that Concept for Addressing of Information within Documents. I still want to use the automatic Anchor-Generation of Markdown, therefore I decide to use a Heading with Level 6 (###### NUMBER) as explicite Anchors.
But when I saw the rendered Result it looked very messy. So finally I used the invisible <a> Html-Tag as Anchor:
<a name="10002"></a>
#### Blog-Chain-Time 2023.04.12-15:14 in Tübingen
Then I added to each Blog-Entry a Topic using a Level-6-Heading:
<a name="10002"></a>
#### Blog-Chain-Time 2023.04.12-15:14 in Tübingen
###### Topics: Clothing, Riddle
After done that, I render all Pages to Html and realize the next Problem:
## 2023.04.12
#### Blog-Chain-Time 2023.04.12-14:46 in Tübingen ###### Topics: Clothing, Geography, Justice
Perhaps the Pandoc-Tool does not like Level-6-Headings? Let’s create a Test-File, …
✔ ~/All-Dings/111 [Rendering L|✚ 1…1096] 19:28
$ cat test.md
# Level 1
## Level 2
### Level 3
#### Level 4
#### Level 5
##### Level 6
###### Level 7
… convert it with Pandoc into Html, …
✔ ~/All-Dings/111 [Rendering L|✚ 1…1096] 19:28
$ pandoc --standalone --template 300000002.htm test.md -o test.html
… and check the Output:
✔ ~/All-Dings/111 [Rendering L|✚ 1…1096] 19:30
$ cat test.html
<!doctype html>
<html lang="en">
<head>
<style>
pre {
background-color: #F8F9FA;
border-style: solid;
border-color: #A1AAB1;
border-radius: 4px;
padding: 5px;
}
</style>
<meta charset="utf-8">
<meta name="date" content=''>
<title></title>
</head>
<body>
<h1 id="level-1">Level 1</h1>
<h2 id="level-2">Level 2</h2>
<h3 id="level-3">Level 3</h3>
<h4 id="level-4">Level 4</h4>
<h4 id="level-5">Level 5</h4>
<h5 id="level-6">Level 6</h5>
<h6 id="level-7">Level 7</h6>
</body>
</html>
Obviously the Problem is the Html-Tag in front of the Markdown-Heading:
✔ ~/All-Dings/111 [Rendering L|✚ 1…1096] 19:34
$ cat new-test.md
<a name="10002"></a>
#### Blog-Chain-Time 2023.04.12-14:46 in Tübingen
###### Topics: Clothing, Geography, Justice
As a Quick-Fix I found that putting the Html-Tag within the Heading worked:
✔ ~/All-Dings/111 [Rendering L|✚ 1…1096] 19:37
$ cat latest-test.md
#### Blog-Chain-Time 2023.04.12-14:46 in Tübingen <a name="10002"></a>
###### Topics: Clothing, Geography, Justice
Like so often in Informatics you try around until it works, but back to the Concepts:
Currently we have three different Types of Information-Containers:
- Repositories
- Number-Files
- Documents
Repositories contain Number-Files, Number-Files contain Documents, Documents contain e.g. Blog-Entries [1]. We have the following Addressing for every Piece of Information that we can use for References from other Information:
- Repository-Number
- Number-File-Number
- Html-Tag-Number
The first two Numbers currently are unique in the Scope of this Project, but the Html-Tag-Number is only unequivocal within the Document.
What makes the Things even more complicated is the Fact that Information Containers can change over Time. So when we e.g. reference a Blog-Entry from another Blog-Entry, after some Days the Content of the first one could have canged, which then makes the Reference from the second one somehow invalid.
There are several Solutions to that Problem:
- Use a Time-Stamp in the Reference
- Use a Hash-Value for the Information in the Reference
- Don’t use References and instead copy the Information
- Try to keep the whole Project consistent at one Point in Time
My current Approach to solve the Problem of Consistency is Solution 4. Therefore I try make one Day as consistent as possible. With Git it is still possible to checkout and render old Days. So if you are interested in the Truth of the Past you still can find it.
And if some Information changes or moves, I try my best to update all the References in the Project so that the current Day is halfway consistent again.
Blog-Chain-Time 2023.04.12-22:48, I now updated this Document with Html-Tags and Links.
To save Time and Space I use now a Self-Closing-Tag as Anchor:
## Day-19: Consistenty <a id="1900"/>
Seems to work, but I did not understand everything …

[1] BTW, what I have just written on Information-Containers is also not 100% correct, because Number-Files could also be Repositories again, which makes the Bit-Mess even bigger.
Day-18: Connect Repositories 1
Topics: Programming
Blog-Chain-Time 2023.04.11-12:27 in Tübingen, As already Yesterday I gave up the Concept of a single Repository that contains all Number-Files.
I now create a new Repository for my Problem with the Medical-Psychological-Assessments and use the Number 1000001000 for the Landing-Page. So now I have four Repositories:
### 1000001000
1000001000 About-Medical-Psychological-Assessment

300000007.md All-Dings-Rendering-Repository
17.md All-Things
### 0
300000008.md All-Dings-Abbreviation-Character
Since I want to use the Landing-Page also for the Git-Hub Readme-File, I create a Unix-Hard-Link:
✔ ~/All-Dings/1000001000 [main|✚ 1] 13:06
$ rm README.md
✔ ~/All-Dings/1000001000 [main|✚ 1] 13:06
$ ln 1000001000.md README.md

Then I create also for the other Repositories the Landing-Pages and move the Sorted-Things Number-File from the 0-Repository to the 111-Repository:
### 1000001000

Number-Files Moves
I now have moved several Number-Files between Repositories, which adds Complexity and makes it harder to keep the Overview on all my Things.
For Example, to get the full History of a Number-File, we have to check all Repositories:
✘-1 ~/All-Dings/0 [Master ↓·3|…1] 15:27
$ for Repository in $(ls ..); do (cd ../$Repository; git log --pretty="format:%ci %h %s" -- 300000007.md;) ; done

2023-04-10 20:50:40 +0200 b61bf6e Move 300000007.md from 0-Repository to 111-Repository
The Number-File 300000007.md first lived in the 0-Repository …
✘-1 ~/All-Dings/0 [Master ↓·3|…1] 15:33
$ git log --pretty="format:%ci %h %s" -- 300000007.md
2023-04-10 20:53:40 +0200 1650178 Move 300000007.md from 0-Repository to 111-Repository
2023-04-08 19:38:28 +0200 71a7fdf Add All-Dings-Rendering-Repository
… and then was moved into the 111-Repository:
✔ ~/All-Dings/111 [Master ↓·3|…1] 15:26
$ git log --pretty="format:%ci %h %s" -- 300000007.md

2023-04-10 20:50:40 +0200 b61bf6e Move 300000007.md from 0-Repository to 111-Repository
Now let’s look for a Bash-Script to find out in which Repository-Number we currently are:
✔ ~/All-Dings/111 [Master ↓·3|…1] 15:44
$ git remote -v | grep -E ".*[0-9]+\.git" | head -1 | sed -E 's#.*Dings/([0-9]+)\.git.*#\1#g'

Blog-Chain-Time 2023.04.10-15:56 in Tübingen, Let’s work Today again on the Rendering Idea.
Currently the HTML-Pages look really Old-Shool and for getting a bit more Style into the Show, the so called Cascading-Style-Sheets, or shortly CSS have been invented.
For adding a Light-Grey Background with rounded Borders to our Code-Blocks, I first test different Options using the W3-Schools Web-Site [[0]]((1610) and then finally add the following CSS-Code to the All-Dings-HTML-Template-File:

For the Rendering-Repository I would like to add now all known All-Dings-Repositories using Git-Submodules again.
First I create a empty new Branch using the Git-Checkout-Command with the --orphan Option:
✔ ~/All-Dings/111 [Rendering|✔] 19:49
$ git checkout --orphan Master
Switched to a new branch 'Master'
As expected the Branch has no Commits:
✔ ~/All-Dings/111 [Master L|●995] 19:50
$ git log
fatal: your current branch 'Master' does not have any commits yet
First let’s get rid of the old Files from the Rendering-Branch using the Git-Reset-Command and the Git-Clean-Command:
✔ ~/All-Dings/111 [Master L|…1] 20:00
$ git reset && git clean -fx
Then we add the 0-Repository as first Sub-Module, …
✔ ~/All-Dings/111 [Master L|…1] 20:01
$ git submodule add git@github.com:All-Dings/0.git

BTW, with this I give up the Concept that all Numbers are available in the 0-Repository. Instead now each Number-File can move between the All-Dings-Repositories.
The same Thing is then done for the Number-File 300000007.md with the Name All-Dings-Rendering-Repository:

Day-16: Rendering 2
Topics: Programming
Blog-Chain-Time 2023.04.09-09:13 in the S-Bahn to Stuttgart, I look into the Phishing-Warning from Yesterday.
Interestingly the Symptom of the Problem depends on the Web-Browser: With the Chrome-Web-Browser the Phishing-Error-Page is loaded and the Safari-Web-Browser shows my Sorry-Page.
My Hpyothesis is that the new Soft-Link to the Readme-File triggers this Problem.
Revert Soft-Link Changes?
First let’s check the Git-History with the Git-Log-Command using the --oneline Command-Option that creates compact Output using shortened 8-Character-Git-Hashes:
✔ ~/All-Dings/0 [Master ↓·20|…1] 09:54
$ git log --oneline .github/README.md
6df58b0 Move README.md -> .gitconfig/README.md
02c9f3e Remove Soft-Link again
1e740d0 Add Soft-Link 888.md -> README.m
To undo the changes I first try the Git-Revert-Command, …
✔ ~/All-Dings/0 [Master|…1] 10:01
$ git revert 6df58b0
Auto-merging 300000006.md
CONFLICT (content): Merge conflict in 300000006.md
error: could not revert 6df58b0... Move README.md -> .gitconfig/README.md
hint: After resolving the conflicts, mark them with
hint: "git add/rm <pathspec>", then run
hint: "git revert --continue".
hint: You can instead skip this commit with "git revert --skip".
hint: To abort and get back to the state before "git revert",
hint: run "git revert --abort".
… that fails, because the Commit touches a File that has been changed in the Meantime, so let’s abort this Approach:
✘-1 ~/All-Dings/0 [Master|REVERTING|●2✖ 1…1] 10:03
$ git revert --abort
In the Meantime I changed my Plan and now I want to generate the Readme-File at Rendering-Time using our Makefile from Yesterday.

Switched to branch 'All-Dings.0-Master'

Your branch is based on 'Origin/main', but the upstream is gone.

As expected the Mix-Case Index.html is ignored by the Webserver, so we have to use Lower-Case index.html:

Day-15: Rendering 1
Topics: Programming
Blog-Chain-Time 2023.04.08-14:59 in Tübingen, I have the Intuition or Feeling that the Idea with Git-Submodules and Git-Hub-Pages was not a good one.
The new Idea is to use the Pandoc-Tool to render each Day the the Content of the All-Dings-Repositories.
According to a nice How-To [1] I first create for an All-Dings-Html-Template.
Then I create the All-Dings-Html-Makefile that should control the Rendering-Process.
The Make-Command is a widely used Tool for Automation in the Informatics.
All-Things-Makefile-File
Now I write the first Makefile-Rules to create Html-Files out of all the Markdown-Files:
✔ ~/All-Dings/0 [Master ↓·10|✚ 2…387] 16:13
$ cat 300000004.make
# # All-Things-Makefile-File
#
Md-File-List = $(wildcard *.md)
Html-File-List = $(subst .md,.html,$(Md-File-List))
all: Html-Files
echo "All-Things-Makefile-File"
Html-Files: $(Html-File-List)
%.html: %.md
pandoc --standalone --template 300000002.html $< -o $@
.PHONY: all
Then I trigger the first Build-Process:
✔ ~/All-Dings/0 [Master ↓·12|✚ 1…2] 16:17
$ make -f 300000004.make
pandoc --standalone --template 300000002.html 0.md -o 0.html
[WARNING] This document format requires a nonempty <title> element.
Defaulting to '0' as the title.
To specify a title, use 'title' in metadata or --metadata title="...".
pandoc --standalone --template 300000002.html 1.md -o 1.html
[WARNING] This document format requires a nonempty <title> element.
Defaulting to '1' as the title.
To specify a title, use 'title' in metadata or --metadata title="...".
[...]
[WARNING] This document format requires a nonempty <title> element.
Defaulting to 'README' as the title.

echo "All-Things-Makefile-File"
All-Things-Makefile-File
This creates a lot of new Html-Files:

In order to be able to distinguish e.g. All-Dings-Html-Makefile from the generated Output-Files, I decide to use the alternative File-Suffix .htm instead of .html for the Input-File.
The Output-Files look almost good, …

… but the References are not working because they still point to the Markdown-Files:
I am called <a href="4.md">Holyheu</a>
Because I do not find a Pandoc-Tool Option for automatic Conversion, I want to write a Regular-Expression for the Unix-Sed-Tool to replace the File-Suffix .md with .html.
But first make a more simple Experiment, where I use a Unix-Pipe to redirect the Output of the Cat-Command to the Input of the Sed-Tool and then replace the String I am with the new String We are:

Blog-Chain-Time 2023.04.08-18:11 in Tübingen, My Plan is to create a new Rendering-Repository that contains the latest Content and the Idea is to use Git-Pull-Force to update it.
But first I want to replace the REAMDE-File with a new All-Dings-Landing-Page, which can be done with by creating a Unix-Soft-Link in the Git-Hub-Config-Directory:
So I first we create the .github Directory9000019.md with the Unix-Mkdir-Command, …
19:21 $ mkdir .github
✔ ~/All-Dings/0 [Master|…2]
… then use the Unix-Mv-Command with the -f Short-Command-Option to force the Move of the old Readme-File, …
✔ ~/All-Dings/0 [Master|…2]
19:21 $ mv -f README.md 300000006.md
… afterwards we remove the old Readme-File with the Git-Rm-Command, …
✔ ~/All-Dings/0 [Master|✚ 2…2]
19:22 $ git rm README.md
rm 'README.md'
… then change into the .github directory with the Unix-Cd-Command, …
✔ ~/All-Dings/0 [Master|●1✚ 1…2]
19:22 $ cd .github/
… and create a Unix-Soft-Link using the Unix-Ln-Command with the Short-Command-Option -s, …
✘-1 ~/All-Dings/0/.github [Master|●1✚ 1…2]
19:23 $ ln -s ../300000006.md README.md

✔ ~/All-Dings/0/.github [Master|●1✚ 1…3]
19:24 $ git add ../300000006.md README.md
… then fire up the Git-Commit-Command with the Long-Command-Option --message to create a new Git-Commit with a meaningful Git-Commit-Message …

Create All-Dings-Rendering-Repository
Now we create our All-Dings-Rendering-Repository which get a meaningful Number regarding Unix-Output:
✔ ~/All-Dings
19:40 $ git clone git@github.com:All-Dings/111.git
Cloning into '111'...
warning: You appear to have cloned an empty repository.
First let’s rename the Git-Remote according to our current Naming-Conventions:
✘-HUP ~/All-Dings/111 [main L|✔] 19:43
$ git remote rename origin Origin
✔ ~/All-Dings/111 [main L|✔]
Then initialize the new Repository with the Git-Init-Command …
✘-128 ~/All-Dings/111 [main L|✔] 19:51
$ git init
Reinitialized existing Git repository in /Users/michael-holzheu/All-Dings/111/.git/
… and create a new Git-Branch Rendering:
✔ ~/All-Dings/111 [main L|✔] 19:58
$ git branch -M Rendering
Now we add a new Git-Remote for our 0-Repository …
✔ ~/All-Dings/111 [Rendering L|✔] 19:59
$ git remote add All-Dings.0 git@github.com:All-Dings/0.git
… and check our Git-Remotes with the Git-Remote-Command using the --verbose Long-Command-Option:
20:02 $ git remote --verbose

Origin git@github.com:All-Dings/111.git (fetch)
Origin git@github.com:All-Dings/111.git (push)
First we have to download the Contenst of the All-Dings.0 Git-Remote into our local Repository using the Git-Fetch-Command:

Searching in the Internet I find a “Solution” [2] for the Problem. Although it will rewrite the Git-History, I’ll give it a Chance:
✘-2 ~/All-Dings/111 [Rendering|✔] 21:16
$ git lfs migrate export --everything --include 8.jpg

Blog-Chain-Time 2023.04.08-21:15 in Tübingen, I really want to finish this Today, so I try the next “Solution” [3]:
✘-2 ~/All-Dings/111 [Rendering|✔] 21:16

This somehow reminds me to a Holiday with Nicole in Romania [0], buts let’s stay professional and look in the 0-Repository for the bad LFS-Commit:
✔ ~/All-Dings/0 [Master ↓·3|…3] 21:46
$ git log 8.jpg
commit df322ecea6b01efb9dc4e02e0aaf3d8771fe5875 (tag: Day-0)

With the Git-Diff-Command I see this Commit does not only contain the 8.jpg File:
21:50 $ git diff --stat df322ecea6b01efb9dc4e02e0aaf3d8771fe5875 | head -5
.github/README.md | 1 +
.gitignore | 16 +
0.md | 16 +-
1.md | 8 +-
100.md | 3 +
But interestingly it does not show our Problem-Child:
✔ ~/All-Dings/0 [Master ↓·3|…3] 21:51
$ git diff --stat df322ecea6b01efb9dc4e02e0aaf3d8771fe5875 | grep 8.jpg
LFS Fix-Idea
Now I get the Idea to build my Render-Branch by using the Git-Cherry-Pick-Command for the “good” Commits and manually apply the “bad” LFS-Commit.
So I first get the Git-History of the 0-Repository using the Git-Log-Command:
✔ ~/All-Dings/0 [Master ↓·6|…4]
22:02 $ git log --pretty=format:"%H" > history.txt
Using the Unix-Head-Command on the File, we can see the Git-Hashes for every Commit:
22:03 $ head -n 3 history.txt
bd97114cefeb0752fd3a08caa34dc301bf9fe1c2
cdf60668c83df30a64fcd915b0378754f8d61b49
1f69fecb240f5e0215cc09384da905f9b8d51504
The first Hash bd97114cefeb0752fd3a08caa34dc301bf9fe1c2 belongs to our last Commit:
✔ ~/All-Dings/0 [Master ↓·8|…4] 22:06

So now let’s got back in History to this very first Commit by first using the Git-Checkout-Command:
✔ ~/All-Dings/0 [Master|…7] 22:30
$ git checkout df322ecea6b01efb9dc4e02e0aaf3d8771fe5875
Note: switching to 'df322ecea6b01efb9dc4e02e0aaf3d8771fe5875'.
You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.
If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:
git switch -c <new-branch-name>
Or undo this operation with:
git switch -
Turn off this advice by setting config variable advice.detachedHead to false
HEAD is now at df322ec Add initial content

Day-14: Git-Hub-Pages
Topics: Programming
Blog-Chain-Time 2023.04.07-19:31 on my Way to Nicole, I continue working on the Sub-Module 404 Problem from Yesterday.
My new Idea is to use Git-Hub-Pages.
It is possible to automatically generate Html-Pages out of the Markdown Files.
After I have enabled this on the 0-Repository and the 888-Repository it looks promising:
- 0-Repository: https://all-dings.github.io/0
- 888-Repository: https://all-dings.github.io/777
Blog-Chain-Time 2023.04.07-20:31 in the U-Bahn to Nicole, Looks like it takes some Time until the Git-Hub-IO Pages are updated.
Blog-Chain-Time 2023.04.08-00:36 on my Way to Dettenhausen, I found out that external Links to Git-Hub-IO Pages should point to HTML- and not to Markdown-Pages.
Blog-Chain-Time 2023.04.08-00:42 on my Way to Dettenhausen, Try to add / to make the File-Path for Images absolute.
Day-13: Dangerous Sub-Modules
Topics: Programming
Blog-Chain-Time 2023.04.06-14:09 in Tübingen, I continue working on the Concept of Git-Sub-Modules.
First I change the Name of my Fork-Repository on Git-Hub from COC-Metzingen-with-Nicole to 888.
Blog-Chain-Time 2023.04.06-18:12 in Tübingen, After some Experiments I decided to rename the Clash-of-Clans Upstream-Repository into “0” and move it into a new Git-Hub-Organization called All-Dings.
Then I deleted the old 888-Repository, replaced it by a new one and changed the Language from German to English.
Since all these Operations have been a little bit dangerous, I now also disabled Git-Force-Push on Git-Hub for both Repositories to protect myself from doing silly Things.
Setup Git-Sub-Module
Now I setup a Git-Sub-Module in the 888-Repository for the moved 0-Repository:
18:10 $ git submodule add git@github.com:All-Dings/0.git
Cloning into '/Users/michael-holzheu/All-Dings/888/0'...
remote: Enumerating objects: 2538, done.
remote: Counting objects: 100% (934/934), done.
remote: Compressing objects: 100% (395/395), done.
remote: Total 2538 (delta 512), reused 847 (delta 459), pack-reused 1604
Receiving objects: 100% (2538/2538), 6.43 MiB | 6.66 MiB/s, done.
Resolving deltas: 100% (1304/1304), done
This creates a new Sub-Directory in the 888-Repository that we can see with the Unix-Ls-Command:
18:31 $ ls -l
total 8
drwxr-xr-x 351 michael-holzheu staff 11232 6 Apr 18:31 0
-rw-r--r-- 1 michael-holzheu staff 27 6 Apr 18:08 README.md
With the Git-Status-Command we see that besides of the 0-Directory also a hidden File Named .gitmodules has been created:
18:35 $ git status
On branch main
Your branch is up to date with 'origin/main'.
Changes to be committed:
(use "git restore --staged <file>..." to unstage)
new file: .gitmodules
new file: 0
The Unix-Cat-Command shows us the Content of this File:
✔ ~/All-Dings/888 [main|●2] 18:37
$ cat .gitmodules
[submodule "0"]
path = 0
url = git@github.com:All-Dings/0.git
According to the very good How-To [0] for Git-Sub-Modules, I now check what Git tells us about our new Sub-Module with the Git-Diff-Command:
✔ ~/All-Dings/888 [main|●2] 18:52
$ git diff --cached 0
diff --git a/0 b/0

Finally I push the Commit to the remote 888-Repository on Git-Hub:

Check Result
On Git-Hub this looks then like the Following:
To test what we have just created, we delete first our local Copy of the 888-Repository …
✔ ~/All-Dings 19:35
$ rm -rf 888/
… and then use the Git-Clone-Command to get a fresh Copy from Git-Hub:
✔ ~/All-Dings 19:35
$ git clone git@github.com:All-Dings/888.git
Cloning into '888'...
remote: Enumerating objects: 9, done.
remote: Counting objects: 100% (9/9), done.
remote: Compressing objects: 100% (5/5), done.
remote: Total 9 (delta 0), reused 6 (delta 0), pack-reused 0
Receiving objects: 100% (9/9), done.
With the Du-Unix-Command we see that the Size of the 888-Repository with 128 Kilo-Byte is quite modest:
✔ ~/All-Dings/888 [Master|✔]
19:39 $ du -sh .
124K .
This is because the Content of the 0-Repository Sub-Module is not yet on our Disk-Drive:
✔ ~/All-Dings/888 [Master|✔]
19:39 $ ls 0/
✔ ~/All-Dings/888 [Master|✔]
For getting the Content of 0-Repository we use the Git-Sub-Module-Init-Command, …
✔ ~/All-Dings/888 [Master|✔]
19:41 $ git submodule init
Submodule '0' (git@github.com:All-Dings/0.git) registered for path '0'
… followed by the Git-Sub-Module-Update-Command:
✔ ~/All-Dings/888 [Master|✔]
19:45 $ git submodule update
Cloning into '/Users/michael-holzheu/All-Dings/888/0'...
Submodule path '0': checked out '29783d2cf991a95276404811054dcd640d77a733
Now our Project consumes much more Space …
✔ ~/All-Dings/888 [Master|✔]
19:48 $ du -sh .
13M .
… and we can use the Unix-Find-Command to see our beloved Things form the 0-Repository again:
✔ ~/All-Dings/888 [Master|✔]
19:54 $ find 0 | sort -V | head -7
0
0/.git
0/.gitattributes
0/.gitignore

Add Reference
Now it is time to add the first Reference Michael from our 888-Repository to the 0-Repository Sub-Module …
✔ ~/All-Dings/888 [Master|✔] 20:11
$ printf "\nOn Monday, April-2023-03 Nicole and [Michael](0/0.md) visited the town of Metzingen to shop for some nice new Clothes." >> README.md
… and then commit and push the Result:
✔ ~/All-Dings/888 [Master ↓·1|✚ 1]

Fix Tracking-Repository
I have asked a Friend to regularly pull from my Clash-of-Clans Repository and Today he sends me an E-Mail that after my Move to All-Dings he gets the Error Repository not found.
Then he sends me the compressed Archive-File of his latest local Snaphot:
✔ ~/All-Dings 02:01
$ ls -lh Clash-of-Clans.tgz
-rw-r--r--@ 1 michael-holzheu staff 9,9M 7 Apr 01:26 Clash-of-Clans.tgz
I use the Unix-Tar-Command to uncompress and unpack the Archive:
✘-1 ~/All-Dings 02:07
$ tar xf Clash-of-Clans.tgz && cd Clash-of-Clans
Then I look for the last Commit that obviously is over two Days old:
commit 74bc0c400e5a9848d7f01d11a3af7ae279d898dc
Author: Michael Holzheu <michael@holzheu.de>
Date: Tue Apr 4 18:24:50 2023 +0200
Add Strategy
It is clear that my Friend’s last Git-Pull-Command failed, because his Git-Remote points to the old URL:
✘-HUP ~/All-Dings/Clash-of-Clans [Master|✔] 02:08
$ git remote -v
origin https://github.com/michael-holzheu/Clash-of-Clans.git (fetch)
origin https://github.com/michael-holzheu/Clash-of-Clans.git (push)
To fix that Problem we can use the Git-Remote-Command to set the new URL:
✘-HUP ~/All-Dings/Clash-of-Clans [Master|✔] 02:16
$ git remote set-url origin git@github.com:All-Dings/0.git
✔ ~/All-Dings/Clash-of-Clans [Master|✔]
Now the Git-Pull-Command works again …
✔ ~/All-Dings/Clash-of-Clans [Master|✔] 02:22
$ git pull

Day-12: Two Universesy
Topics: Programming
Blog-Chain-Time 2023.04.05-15:42 in Tübingen, Today I would like to work again on a Concept for storing Media-Files efficiently in the Project:
My current Idea is to use Git-Sub-Modules for this Purpose.
Create Git-Fork
For makeing some Tests I first create a Git-Fork of the original Ropository. First I create a Copy of the Repository:
~/Clash-of-Clans$ cd ..
~$ cp -r Clash-of-Clans/ Clash-of-Clans-Fork
~$ cd Clash-of-Clans-Fork/
~/Clash-of-Clans-Fork$
I remove the Git-Remote “origin” from the Project:
~/Clash-of-Clans-Fork$ git remote -v
origin git@github.com:michael-holzheu/Clash-of-Clans.git (fetch)
origin git@github.com:michael-holzheu/Clash-of-Clans.git (push)
~/Clash-of-Clans-Fork$ git remote remove origin
~/Clash-of-Clans-Fork$ git remote -v
I create on Git-Hub an empty new Repository with the Name “Clash-of-Clans-Fork” and then add its URL as Git-Remote to the Repository:
~/Clash-of-Clans-Fork$ git remote add Origin git@github.com:michael-holzheu/Clash-of-Clans-Fork.git
~/Clash-of-Clans-Fork$ git remote -v
Origin git@github.com:michael-holzheu/Clash-of-Clans-Fork.git (fetch)
Origin git@github.com:michael-holzheu/Clash-of-Clans-Fork.git (push)
Then I use Git-Push to upload the Data to Git-Hub:
~/Clash-of-Clans-Fork$ git push --set-upstream Origin Master
Enumerating objects: 2249, done.), 604 KB | 0 B/s
Counting objects: 100% (2249/2249), done.
Delta compression using up to 10 threads
Compressing objects: 100% (988/988), done.
Writing objects: 100% (2249/2249), 6.35 MiB | 3.78 MiB/s, done.
Total 2249 (delta 1154), reused 2054 (delta 1039), pack-reused 0
remote: Resolving deltas: 100% (1154/1154), done.
To github.com:michael-holzheu/Clash-of-Clans-Fork.git
* [new branch] Master -> Master
branch 'Master' set up to track 'Origin/Master'.
Because I want to use the Photos of Nicole in Metzingen for the first Sub-Module, I rename the Repository to …
~/Clash-of-Clans-Fork$ cd ..
~$ mv Clash-of-Clans-Fork COC-Metzingen-with-Nicole
Then I add my Upsteam Git-Repository as a new Git-Remote:
~/COC-Metzingen-with-Nicole$ git remote add Upstream git@github.com:michael-holzheu/Clash-of-Clans.git
~/COC-Metzingen-with-Nicole$ git remote -v
Origin git@github.com:michael-holzheu/Clash-of-Clans-Fork.git (fetch)
Origin git@github.com:michael-holzheu/Clash-of-Clans-Fork.git (push)
Upstream git@github.com:michael-holzheu/Clash-of-Clans.git (fetch)
Upstream git@github.com:michael-holzheu/Clash-of-Clans.git (push)
Because I have committed already several Things to the Upstream-Repository the Fork-Repository is a little bit behind in History:
~/COC-Metzingen-with-Nicole$ git log | head -11

Add Git-Fork
We see that the last common Commit is the one with the Hash-Value “97359863a670ffb1cb4aaaefe21fb4a90476368a”. Therefore first I synchronize the backlevel COC-Metzingen-With-Nicole with the Git-Fetch-Command:
~/COC-Metzingen-with-Nicole$ git fetch Upstream
remote: Enumerating objects: 33, done.
remote: Counting objects: 100% (33/33), done.
remote: Compressing objects: 100% (29/29), done.
remote: Total 30 (delta 18), reused 0 (delta 0), pack-reused 0
Unpacking objects: 100% (30/30), 7.72 KiB | 395.00 KiB/s, done.
From github.com:michael-holzheu/Clash-of-Clans
* [new branch] Master -> Upstream/Master
Now all Information about the Upstream-Repository has been downloaded into the Fork-Repository. Next I use the [Git-Rebase-Command] to integrate the latest Changes from the Upstream-Repository’s “Master” Git-Branch into my Fork-Repository “Master” Git-Branch:
~/COC-Metzingen-with-Nicole$ git rebase Upstream/Master
Successfully rebased and updated refs/heads/Master.
With the Git-Log-Command I now can see that …
commit 939bd9c557542db053c9f9f5b014d46f2e41e8fc (HEAD -> Master, Upstream/Master)
Author: Michael Holzheu <michael@holzheu.de>

… the Upstream Repository has been modified in the Meantime again:

Now the Git-Heads of both Repositories are at the same Git-Commit “939bd9c557542db053c9f9f5b014d46f2e41e8fc”:
~/COC-Metzingen-with-Nicole$ git show

Let’s draw a short Diagram to illustrate the current State:

Now let’s create a Directory and a Landing-Page in the Fork-Repository. For this Sub-Project I use the Number 888:
~/COC-Metzingen-with-Nicole$ mkdir 888
Then I create a Landing-Page File with the Name “888.md”:
# Metzingen with Nicole
I meet Nicole on 2003-04-02 in Metzingen to buy some new Cloths and make some Test-Photos for the "Clash-of-Clans" Project.
Because Metzingen is not yet defined in the Upstream-Repository, I create a new Thing with Number 140000010.md in my Fork-Repository.
To make Life a bit easier for me, I switch for a Moment I switch now completely to the Fork-Repository “COC-Metzingen-with-Nicole” …
In my Terminal-Session I now go to my Directory “COC-Metzingen-with-Nicole” and fetch the current State from the Upstream-Repository:
~/COC-Metzingen-with-Nicole$ git fetch Upstream
remote: Enumerating objects: 43, done.
remote: Counting objects: 100% (43/43), done.
remote: Compressing objects: 100% (37/37), done.
remote: Total 39 (delta 24), reused 0 (delta 0), pack-reused 0
Unpacking objects: 100% (39/39), 9.35 KiB | 398.00 KiB/s, done.
From github.com:michael-holzheu/Clash-of-Clans
939bd9c..0f82393 Master -> Upstream/Master
Then I rebase my local Fork-Repository to get all the Updates:
~/COC-Metzingen-with-Nicole$ git rebase Upstream/Master
With the Git-Log Command I look at the current Blog-Chain:
commit cd822cc8a33aea5054e2e1ab5852bf3b5c2d7d44 (HEAD -> Master)

Date: Wed Apr 5 19:51:42 2023 +0200
Switch to Fork Metzingen-with-Nicole
Let’s draw a new Diagram for the current State, where we realize that now the Fork-Repository is 4 Commits ahead of the Upstream-Repository:
+----- Add Metzingen (cd822cc8a33aea5054e2e1ab5852bf3b5c2d7d44 -> Fork-Repository)
|
+----- Add Metzingen
|
+----- Add Metzingen-with-Nicole
|
+----- Add Hash-Value
|
+----- Switch to Fork Metzingen-with-Nicole (0f82393eb01a1122cb3a062e43a4a616c3282ec5 -> Upstream-Repository)
|
To be not confused, I first rename the Git-Remote for my Fork properly:
~/COC-Metzingen-with-Nicole$ git remote rename Origin Fork
Renaming remote references: 100% (1/1), done.
IMHO, now it’s much more clear:
~/COC-Metzingen-with-Nicole$ git remote -v
Fork git@github.com:michael-holzheu/Clash-of-Clans-Fork.git (fetch)
Fork git@github.com:michael-holzheu/Clash-of-Clans-Fork.git (push)
Upstream git@github.com:michael-holzheu/Clash-of-Clans.git (fetch)
Upstream git@github.com:michael-holzheu/Clash-of-Clans.git (push)
Synchronize with Upstream-Repository
Now let’s try to move the new Stuff to the Upstream-Repository. This can be done by a Git-Pull-Request.
For doing that we first need to create a new Git-Branch from the last common Git-Commit that we already identified by its Hash-Value 0f82393eb01a1122cb3a062e43a4a616c3282ec5:
~/COC-Metzingen-with-Nicole$ git branch PR-0-First-Sync 0f82393eb01a1122cb3a062e43a4a616c3282ec5
In our Diagram this then looks like the Following:
+----- Add Metzingen (cd822cc8a33aea5054e2e1ab5852bf3b5c2d7d44 -> Fork-Repository)
|
+----- Add Metzingen
|
+----- Add Metzingen-with-Nicole
|
+----- Add Hash-Value
|
+----- Switch to Fork Metzingen-with-Nicole (0f82393eb01a1122cb3a062e43a4a616c3282ec5 -> PR-0-First-Sync)
|
Now lets do a Git-Checkout of our new Git-Branch:
~/COC-Metzingen-with-Nicole$ git checkout PR-0-First-Sync
Switched to branch 'PR-0-First-Sync'
Then let’s check the Commits on this Branch:
commit 0f82393eb01a1122cb3a062e43a4a616c3282ec5 (HEAD -> PR-0-First-Sync, Upstream/Master)

As expected that last Commit is our known Fork-Point:

Add Reference
In order to see the Git-Branch on the Bash-Prompt I install …
~/COC-Metzingen-with-Nicole$ brew install bash-git-prompt
Running `brew update --auto-update`...
… and then add the following Lines to my Bash-RC-File:
if [ -f "$HOMEBREW_PREFIX/opt/bash-git-prompt/share/gitprompt.sh" ]; then
__GIT_PROMPT_DIR="$HOMEBREW_PREFIX/opt/bash-git-prompt/share"
source "$HOMEBREW_PREFIX/opt/bash-git-prompt/share/gitprompt.sh"
fi
Then I enable the new Function with the Bash-Source-Command and now we can see the currenty active Branch and the Time in the Prompt:

Day-10: The Beauty
Simple Work
Blog-Chain-Time 2023.04.03-08:50 in Tübingen, I started to cleanup some Things:
michael-holzheu@MacBook/Clash-of-Clans $ grep "Cat-Com" *.md
23.md:Before looking into that one, we copy the new [Code](/0/9000039.html) into a separate File [Du-Script](/0/9000038.bash) and check its [Content](/0/600021.html) with the [Cat-Command](/0/9000040.html):
9000040.md:# Cat-Command
9000040.md:The Cat-Command
Though manually renaming Stuff means a lot of Work, for Wakeup in the Morning it has its Beauty and somehow feels more like Fun.
After my simple Work-Item the Indentation-Levels of all Lines are fixed.
German Wireless-Problems
Blog-Chain-Time 2023.04.03-10:20 on my Way to Nicole, I continue to finish the Simple Work …
Because the Wireless-LAN most of the Times does not work in German’s Auto-Buses, I switch to the Git-Hub online User-Interface.
Day-9: An Original
Topics: Programming
Sorted-Things
Blog-Chain-Time 2023.04.02-14:45 in Tübingen, I already created many Numbers for this Project and in order to not lose track of the Situation, I created a List where the Things are ordered more or less according their Number:
$ head -n 4 Almost-Sorted-Things.txt
30010003.md Pixel
30010002.md Full-HD
30010001.md Resolution
30010000.md Media-Formats
First I want to sort the List in the reverse Order:
$ cat Almost-Sorted-Things.txt | sort -nr > Sorted-Things.txt
Next I would like to create a Markdown-Document with Links that is clickable:
$ cat Sorted-Things.txt | (while read Number Name; do printf "%-14s %-20s [Link](%s)\n" $Number $Name $Number; done) > SortedThingsWithMarkDown.md
Looks almost good, but some Things still have to be fixed manually, for Example:
12000000.md Expert [Link](/0/12000000.html)
11091971.md Michael's [Link](Calendar)
11091971.md [Link]() <====
11000000.md History [Link](/0/11000000.html)
Afterwards I append the Result to the README File using the MV-Command:
$ cat README.md SortedThingsWithMarkDown.md > tmp.md
$ mv tmp.md README.md
To make the Links clickable, originally I have added all the Things into a Markdown-List:
- 1000000099.md NinetyNine [Link](/0/1000000099.html)
- 30010003.md Pixel [Link](/0/30010003.html)
- 30010002.md Full-HD [Link](/0/30010002.html)
But somehow I don’t like the Layout. For removing the Links again, I use the following VIM-Command:
:%s/\s\+\[Link.*//g
Now it looks like the Following:
- 1000000099.md NinetyNine
- 30010003.md Pixel
- 30010002.md Full-HD
- 30010001.md Resolution
To replace the leading Bullets, I enter the VIM-Visual-Mode with the Control-v Keyboard-Shortcut, then remove the leading Bullets and finally I mark the whole Section with “```” as a Markdown-Code-Block:
1000000099.md NinetyNine
30010003.md Pixel
30010002.md Full-HD
30010001.md Resolution
Big Things (again)
Now I come back to my old Question, how to store big Files in this Project. After I having rejected the idea of using LFS, now another Idea came to my Mind.
What about storing the Big-Data seperate from the Not-So-Big-Data?
Sample Image
I plan to test the new Concept with a Picture-for-Nicole:
According my current Rules I stored it in Full-HD Resolution in my Clash-of-Clans GIT-Repository, where all the Files together currently have the Size of about 4 Megabytes:
~/Clash-of-Clans$ bash 9000038.bash | tail -n 2
README.md 3967 4121912
./2000002.md 34 4121879
The Byte-Size of our Picture in JPG-Image-Format is …
~/Clash-of-Clans$ ls -l 55.jpg
-rw-r--r-- 1 michael-holzheu staff 905873 2 Apr 19:08 55.jpg
If we divide the Size of 905.873 Bytes by 1024 we get around 900 Kilo-Bytes.
Then I use the Image-Editing Application Gimp for converting the Image from compressed JPG-Image-Format into RAW-Image-Format and check its Byte-Size:
~$ ls -l 55.raw
-rw-r--r-- 1 michael-holzheu staff 29942784 2 Apr 21:08 55.raw
So now the same Picture in that Format uses 29.942.784 Bytes or around 30 Mega-Bytes of my Disk-Drive.
Compression
The Reason for the 29 Mega-Bytes Difference between JPG and RAW is Compression: The JPG-Image-Format is highly compressed and still provides enough Information for Rendering the Picture in a way that a Human can understand its Meaning.
The higher we make the Compression-Level, the lower is the File-Size:
michael-holzheu@MacBook/55 $ ls -lS
total 72528
-rw-r--r-- 1 michael-holzheu staff 29942784 2 Apr 21:08 55.raw
-rw-r--r-- 1 michael-holzheu staff 2382877 2 Apr 21:56 55-100.jpg
-rw-r--r-- 1 michael-holzheu staff 2382877 2 Apr 21:56 55-80.jpg
-rw-r--r--@ 1 michael-holzheu staff 905873 2 Apr 21:59 55-94.jpg
-rw-r--r-- 1 michael-holzheu staff 905873 2 Apr 21:56 55.jpg
-rw-r--r-- 1 michael-holzheu staff 243910 2 Apr 21:57 55-60.jpg
-rw-r--r-- 1 michael-holzheu staff 181193 2 Apr 21:57 55-40.jpg
-rw-r--r-- 1 michael-holzheu staff 118690 2 Apr 21:57 55-20.jpg
-rw-r--r-- 1 michael-holzheu staff 50984 2 Apr 21:57 55-00.jpg
But the lower the Compression-Level, the lower is also the Quality:
About Quality
Hmm, I somehow like the highly-compressed Image, so probably we have to specify the Meaning of Quality a bit more.
For Example, when we get into the Territory of Fine-Arts, it is not so easy to measure the Quantity of a Picture.
In the Context of Photography at first Glance it seems much simpler, because a Photo should come close to Reality. So in this Respect the higher compressed Image has less Quality.
And the highest Quality regarding Reality should have the Orignal, no?
The Original
In Photography the “best” Image-Format regarding Quality is probably the uncompressed RAW-Image-Format, but for our Example this is a bit more complicated.
The Reason is that current Smart-Phones normally store the Photos already in JPG-Image-Format and this is also the case for our Picture-for-Nicole.
When I convert the compressed Image back to RAW-Image-Format, we probably even loose Qualtiy because during the Conversion Image-Information will be lost.
If we assume that by Definition the Original is the Image with the best Quality, by Logic we can come to the Conclusion that our the JPG-Image is original.
But wait …
According to my Rules I already resized the Image to Full-HD Format, therefore the File in this Repository is not the Original.
So let’s copy the “Original” into our Directory:
michael-holzheu@MacBook/55 $ ls -lS
total 75288
-rw-r--r-- 1 michael-holzheu staff 29942784 2 Apr 21:08 55.raw
-rw-r--r-- 1 michael-holzheu staff 2382877 2 Apr 21:56 55-100.jpg
-rw-r--r-- 1 michael-holzheu staff 2382877 2 Apr 21:56 55-80.jpg
-rw-r--r--@ 1 michael-holzheu staff 1409592 2 Apr 19:04 original_60bf61ca-6207-4ed8-a563-17186415691b_20230401_141946.jpg
-rw-r--r--@ 1 michael-holzheu staff 905873 2 Apr 21:59 55-94.jpg
-rw-r--r-- 1 michael-holzheu staff 905873 2 Apr 21:56 55.jpg
-rw-r--r-- 1 michael-holzheu staff 243910 2 Apr 21:57 55-60.jpg
-rw-r--r-- 1 michael-holzheu staff 181193 2 Apr 21:57 55-40.jpg
-rw-r--r-- 1 michael-holzheu staff 118690 2 Apr 21:57 55-20.jpg
-rw-r--r--@ 1 michael-holzheu staff 50984 2 Apr 21:57 55-00.jpg
With its 1,4 Megabytes in Terms of File-Size it lies beetween the two Full-HD Images with 80% and 94% Compression.
This sounds good at first glance, but now let’s use the Exif-Tool to check the Image-Size:
michael-holzheu@MacBook/55 $ exiftool original_60bf61ca-6207-4ed8-a563-17186415691b_20230401_141946.jpg | grep "Image Size"
Image Size : 3648x2736
This means that we have a Resolution of 3648 Pixels for the Width and 2736 for the Height.
So according to Adam-Ries who is a famous Personality in the Discipline of Mathematics, we have in total …
~/Clash-of-Clans$ echo "... $((3648 * 2736)) Pixels."
... 9980928 Pixels.
Taking into account the File-Size of 1409592 Bytes, this means that one Pixel requires …
~/Clash-of-Clans$ echo "... $((1409592 / 9980928)) Bytes."
... 0 Bytes.
Obviously Arithmethic with more Quality is required here and we better use good-old Floating-Point to get some Precision into the Calculation.
So let’s switch from Bash to a Computer-Language with a little bit more Functions, namely …
michael-holzheu@MacBook/55 $ perl -E "say 1409592 / 9980928"
0.141228551092644
As a Mathematician this Result reminds me to a Famous-Number but this is really pure Coincidence.
Perhaps, perhaps not…
Wouldn’t be Life without any Secrets a litte Bit too boring? Keep your courious and sleep well!
Day-8: Big Data
Topics: Git, Lfs
Blog-Chain-Time 2023.03.31-15:15 in Tübingen, After I finished Tennis Training, good Lunch and Shopping, now it’s Time to find a good Solution for storing Big Data, like Music, Pictures, and Movies.
Up to now my favourite Solution was Git’s Large Files Support, but I already made some unpleasant Experiences with that Software.
Although I already configured the Stuff, it is no longer working. For some Reason the Files are still uploaded directly into the “normal” Git Repository.
The most likely Reason is that I deleted and cloned the Repository many Times and therefore Parts of the Configuration have been lost.
Experiments
In Order not to mess up my Clash-of-Clans I first create a new Repository to play with. But before doing that, I first want to store an Image in the “normal” Clash-of-Clans.
Commit Screenshot to Git
It is a Screenshot in Full-HD that has the Size of 170777 Bytes or equivalent to 167 Kilobytes:
$ ls -l 88.jpg
-rw-r--r-- 1 michael-holzheu staff 170777 1 Apr 16:37 88.jpg
$ ls -lh 88.jpg
-rw-r--r-- 1 michael-holzheu staff 167K 1 Apr 16:37 88.jpg
Repository Data-Size
But before committing the File, first check the old Data-Size of the Repository, which is 19120 Bytes or equivalent (more or less) to 9,3 Mega-Bytes:
$ du -s Clash-of-Clans
19120 Clash-of-Clans
$ du -hs Clash-of-Clans
9,3M Clash-of-Clans
As every Expert in Informatics knows, a Disk-Drive stores Data in Blocks and the Usage of the Device is therefore also shown in that Unit.
So to calculate the Usage in Bytes we first have to find out the Block-Size:
$ diskutil info / | grep "Block Size"
Device Block Size: 4096 Bytes
Allocation Block Size: 4096 Bytes
$ $ stat -f %k .
4096
This means that one Block on My-Mac-Book has 4096 Bytes and therefore the Disk-Drive-Usage can be calculated with …
$ echo "$((4096 * 19120))"
78315520
For Verification we calculate the Size in Mega-Bytes with …
$ echo "$((1000 * 1000))"
1000000
$ echo "$((78315520 / 1000000))"
78
Oehm, as we saw at the beginning the “du -sh” Command told us that the “Clash of Clans” Directory uses 9,3 Mega-Bytes of Disk Storage. The Question is, how does that match to the 78 Mega-Bytes, we calculated by the Blocksize and the “du -s” Command?
Let’s find first out the Sum of the Byte-Sizes of all Files in the Directory:
~/Clash-of-Clans$ ls

That’s a lot of files …
~/Clash-of-Clans$ ls | wc -w
165
Let’s write a “short” Script that forms a Sum over all the File-Sizes:
~/Clash-of-Clans$ ls -l | tail -n +2 | (while read -r Line; do FileSize=$(echo $Line | awk '{print $5}'); FileName=$(echo $Line | awk '{print $9}'); SumSize=$((SumSize + FileSize)); printf "%-16s %8s %5s\n" $FileName $FileSize $SumSize; done)
0.md 442 442
1.md 228 670
100.md 130 800
10000.jpg 43265 44065
...
9000019.md 32 3194690
9000020.md 26 3194716
904.md 120 3194836
README.md 256 3195092
I realize that the Sum over all File-Sizes is 3195092 Bytes, or written different as 3.195.092 Bytes, respective around 3.195 Kilo-Bytes or 3 Mega-Bytes.
We saw above that the DU-Command with the Command-Options “-hs” tells me that the Disk-Usage is 9,3 Mega-Bytes, so where are the missing 6 Mega-Bytes?
Of course every good Computer Expert knows that most Operating-Systems provide File-Systems, that provide Hidden-Files.
Traditionally under Unix hidden Files begin with a Dot and with the so-called Find-Command we can show behind the Scenes and already the first Line of Output shows the hidden Pointer “.” to the current Work-Directory.
~/Clash-of-Clans$ find .
.
./50003.md
./100.md
Looking further down, we see the first “real” Hidden-File, namely …
./20.md
./30.md
./.gitignore
BTW, the Data in the Git-Ignore-File defines all Files that should be ingored by the Git-Command.
But before we come back on that, let’s rewrite our original Skript a bit and use the Grep-Command, the Stat-Command plus some Regular-Expressions for the Calculation of the Disk-Usage:
$ find . -type file | grep -E './[a-zA-Z0-9]*\.(md|jpg|markdown|bash|bashrc)' | (while read -r FileName; do FileSize=$(stat -f "%z" $FileName); SumSize=$((SumSize + FileSize)); printf "%-16s %8s %5s\n" $FileName $FileSize $SumSize; done)
./50003.md 139 139
./9000025.md 36 175
...
./2.md 333 3198498
./2000002.md 34 3198532
Hmm, now we get 3198510 Bytes and the old Script calculated 3195092 Bytes, if I remember correctly, so thats …
~/Clash-of-Clans$ echo "$((3195092 - 3198532)) Bytes less."
-3440 Bytes less.
Of course every real Nerd who thinks he’s something in the Computing Area, knows of course that we created a lot of Files since we ran the old Script the last Time.
Before looking into that one, we copy the new Code into a separate File Du-Script and check its Content with the CAT-Command:
~/Clash-of-Clans$ cat 9000038.bash
# Du-Script
find . -type file | grep -E './[a-zA-Z0-9]*\.(md|jpg|markdown|bash|bashrc)' | (while read -r FileName; do FileSize=$(stat -f "%z" $FileName); SumSize=$((SumSize + FileSize)); printf "%-16s %8s %5s\n" $FileName $FileSize $SumSize; done)
As first Test-Case of the Script I run it with Bash- and the TAIL-Command:
~/Clash-of-Clans$ bash 9000038.bash | tail -n 2
./2.md 333 3198802
./2000002.md 34 3198836
Now let me run the Code again as One-Liner and compare the Output:
~/Clash-of-Clans$ find . -type file | grep -E './[a-zA-Z0-9]*\.(md|jpg|markdown|bash|bashrc)' | (while read -r FileName; do FileSize=$(stat -f "%z" $FileName); SumSize=$((SumSize + FileSize)); printf "%-16s %8s %5s\n" $FileName $FileSize $SumSize; done) | tail -n 2
./2.md 333 3198802
./2000002.md 34 3198836
Now I add the first One-Liner to my Du-Script and add the “tail -n 1” command to both Lines:
~/Clash-of-Clans$ cat 9000038.bash
# Du-Script
# First Script
ls -l | tail -n +2 | (while read -r Line; do FileSize=$(echo $Line | awk '{print $5}'); FileName=$(echo $Line | awk '{print $9}'); SumSize=$((SumSize + FileSize)); printf "%-16s %8s %5s\n" $FileName $FileSize $SumSize; done) | tail -n 1
# Second Script
find . -type file | grep -E './[a-zA-Z0-9]*\.(md|jpg|markdown|bash|bashrc)' | (while read -r FileName; do FileSize=$(stat -f "%z" $FileName); SumSize=$((SumSize + FileSize)); printf "%-16s %8s %5s\n" $FileName $FileSize $SumSize; done) | tail -n 1
So now when running the Script in Theory I would expect to see two Lines showing the same Result, so let’s try it …
~/Clash-of-Clans$ bash 9000038.bash
README.md 256 3201483
./2000002.md 34 3199246
To find out the Reason for the Problem some some Debugging is required. My first Hypothis is that the second Script for why ever finds less Files that the first one.
And indeed, after I checked the List of File-Types and realized that three of them are missing, I add them to the second Script:
~/Clash-of-Clans$ git diff
diff --git a/9000038.bash b/9000038.bash
index 748352c..d175d9c 100644
--- a/9000038.bash
+++ b/9000038.bash
@@ -4,4 +4,4 @@
ls -l | tail -n +2 | (while read -r Line; do FileSize=$(echo $Line | awk '{print $5}'); FileName=$(echo $Line | awk '{print $9}'); SumSize=$((SumSize + FileSize)); printf "%-16s %8s %5s\n" $FileName $FileSize $SumSize; done) | tail -n 1
# Second Script
-find . -type file | grep -E './[a-zA-Z0-9]*\.(md|jpg|markdown|bash|bashrc)' | (while read -r FileName; do FileSize=$(stat -f "%z" $FileName); SumSize=$((SumSize + FileSize)); printf "%-16s %8s %5s\n" $FileName $FileSize $SumSize; done) | tail -n 1

Now I am confident that both Scripts will show the same Result now:
~/Clash-of-Clans$ bash 9000038.bash
README.md 256 3201540
./2000002.md 34 3201510
Oh Boy, still not finished, let’s look at our Files again:

Day-7: Problems
Topics: GFR
DB-Navigator Problem
Blog-Chain-Time 2023.03.31-01:20, We looked up for a Train back to Tübigen and the DB-App shows me a possible Connection. Nice, so I can save the Money for the Taxi. After I waiting 20 Minutes on the Subway-Platform, I read the Timetable which then tells me that there are no more trains at this time.
So looks like this is a Problem with the DB-Navigator.
Samsung Pen Problem
Blog-Chain-Time 2023.03.31-00:36, I show Nicole my Project and she suggests to use the Pen of my Samsung-Galaxy-S22-Ultra and test Handwriting. After 10 Minutes fighting with Problems we stopped the Experiment.
Electricity Problem
Blog-Chain-Time 2023.03.31-22:18 on my Way to Nicole, This time I did not forget my Charging-Device for the MacBook and fortunately the German-Federal-Raiload provides Electricity, Problem solved!
Heil-und-Kostenplan Problem
Blog-Chain-Time 2023.03.31-13:OO in Tübingen, I read an E-Mail from the Singing-Dentist, where he points out that I have forgotten to bring the Heil-und-Kostenplan as I promised.
In fact I was Yesterday Evening at the Dental-Practice. Before putting the Document into the Post-Box, I skimmed it a very last time. Then I noticed a yellow Label:
* Achtung
Sehr geehrter Patient!
Bitte diesen Heil- und Kostenplan
1. zusammen mit dem Bunusheft bei Ihrer Krankenkasse einreichen
2. nach Zuschussfestsetzung durch die Kasse den Antrag bitte umgehend an die Praxis zurück
Unfortunately I only read up to Line Number 4, and then concluded that I have taken the wrong Document. So unfortunatley the Way was for Nothing.
Back home I search for the “right” Document which I - by logical Conclusion - cannot find.
I felt rememinded to my recently lost Work. So I developted the Hypothesis that I might have already delivered the Document. But then I checked my Calendar found out the Truth:
For the first Appointment I brought the wrong Document and I promised to deliver the right one for the next (second) Session. If my Memory does not deceive me, I see almost 100% Probablity that something must have gone wrong.
Therefore I now also read the 5th Line and detected the Reason for my Problem.
After that Realization I grabbed the Heil- und Kostenplan, walked agein to the Dentist and put the Document into his Post-Box.
Day-6: More Concepts
Topics: Concepts
Finished Work
Blog-Chain-Time 2023.03.30-23:25 still on my Way to Nicole, I finished the Work for Today, CU Tomorrow!
About Apple Macbook Pro 14’’ M1
Blog-Chain-Time 2023.03.30-23:17 still on my Way to Nicole, Not a good Time for the Project. Today, my MacBook seems to empty his Battery faster than expected …
About Trust (again)
Blog-Chain-Time 2023.03.30-22:47 still on my Way to Nicole, Believe it or not my first Information Container Concepts have disappeared …
Information Containers
Blog-Chain-Time 2023.03.30-22:34 finally on my Way to Nicole, I start to add Concepts about Information Containers.
About Trust
Blog-Chain-Time 2023.03.30-22:19 on my Way to Nicole, Believe it or not, but our Story about “Micha … (again)” is lost somewhere in all this crazy mess.
Add Theory
Blog-Chain-Time 2023.03.30-20:03 in Tübingen(TBD), Before starting the real work, I first want to summarize the Theory into a List.
Add History
Blog-Chain-Time 2023.03.30-13:27 in Tübingen(TBD), I decided to combine my first Days into this Document for describing the History of this Project.
Day-5: First Concepts
Topics: Concepts
Blog-Chain-Time 2023.03.29-17-25, I am on my Way to Nicole [0] and after the Cleanup Work Yesterday, now I would like to use the Time for adding some new Concepts.
Footnotes
[0] Extra Tour with Nicole: https://www.holzheu.de/extra-tour-with-nicole
Day-4: Big “Cleanup”
Blog-Chain-Time 2023.03.28-22:35 in Tübingen, After Micha did the technical Work Yesterday, today our Creative Chief Officer Michi joined our Party to bring a bit more Pepper into the Souce.
But first I really want to beatify our Work a little bit.
So let’s first check what we have written in the Document [0] with the meaningful Number 99, where obviously Somebody forgot to add a Footnote for this famous saying:
But Caution is the Mother of the Porcelain Box, so let's make some Experiments first.
Our current Favourite Markdown Footnotes have the Drawback that the Numbers have to be specified manually, and to put it strait:
This can sometimes really be really be "Pain in the Ass"!
But before we can come back to that, we have first to define some basic [Things]. Oh Man, perhaps I should not have started that, because after ten Minutes I already created a long List of very important new Things.
But before I could commit those, we first had to define other even more urgent Things, namely Michi, the simple Show Mouse and my Bunnie Page.
And there was a small Problem to enable the Broken Link page - not a big deal, I will do that together with Micha sometime later [1] .
But let’s come back to the starting Point with the Footnotes. Obviously I had been a little bit too optimistic. Obviously on GitHub the modern fancy Features of the Markup Languate have not yet arrived. But this has time until Tomorrow.
So only one more Thing …
Footnotes
Day-3: A nasty Egg
Topics: Bugs
Blog-Chain-Time 2023.03.27-??:?? in Tübingen(TBD), Damn, I forgot to commit my 33.md Baby. Normally this is no big Deal, but unfortunately the already committed 27.md has a Reference to it:
root:~ (devel)# head 27.md
# Echo Bug
Everytime when I execute the [mmls](/0/33.html#mmls) command, a new file "echo" is created.
I am screwed when Someone checks out the Code now and sees the broken Link. So let’s checkin the missing File quickly:
root:~ (devel)# git add 33.md
root:~ (devel)# git commit -s -m "Add 33.md to fix the broken Link in 27.md in the previous commit"
[devel 5a30961] Add 33.md to fix the broken Link in 27.md in the previous commit
1 file changed, 26 insertions(+)
create mode 100644 33.md
Puh, Nobody saw my Mistake and now we are save again:
root:~ (devel)# git log --oneline | head -3
5a30961 Add 33.md to fix the broken Link in 27.md in the previous commit
c3c6df2 Add more Files to ignore
46aa317 Add Echo Bug
But wait, if some Grumpy gets to the crazy idea to check out “Echo Bug” Commit 46aa317, he can still find out my sloppiness. Oh Man, I really have laid myself a nasty egg:
