62 years

I was born on Wednesday, November 1, 1961 at 9:45 in the morning (CET). That means that today, I will be 61 years according to the calendar and 22645 days old. But how old am I really? The tropical year, the time that it takes for the seasons to return, is said to be 365 days, 5 hours, 48 minutes, and 45.19 seconds. Today, around 10:07:41 in the morning, it was 62 tropical years since I was born. But the tropical year is shorter than the sidereal year, the time taken by the Earth to orbit the Sun once with respect to the fixed stars, namely 365 days, 6 hours, 9 minutes, and 9.76 seconds. That means that, tomorrow at 7:13:05 it will be 62 sidereal years after I was born. The average anomalistic year, the time taken for the Earth to complete one revolution with respect to its apsides, is 365 days, 6 hours, 13 minutes, and 52.6 seconds. That means that, tomorrow around 12:05:21 it will be 62 average anomalistic years since I was born.

D, d and b

I am a bit dyslectic. I primarily struggle with spelling and remembering rote facts. I also struggle a bit the letter 'D', 'd' and 'b' when writing software. I am currenlty developing an emulator for the intel 386 processor. (Code can be found here.) In the past two weeks, I again spend a lot of time debugging the code as I wrote about two weeks ago. The last bug I fixed was because I had mixed up the 'edx' and 'ebx' registers for one instruction. This mistake is probably also related to the fact that in some of the sources these registers are called 'EDX' and 'EBX', because I had used 'ebx' where I should have used 'edx'. I wondered why the capital of 'd' id 'D'. In the Greek alphabet the Delta is written like uppercase Δ and lowercase δ. It is not so difficult to see how the lower case became the 'd'. It is interesting to see how it was written in the Fraktur calligraphic hand of the Latin alphabet. In the Latin alphabet the Delta is already written like 'D'. This alphabet is based on the the Old Italic script. where it is found in South Picene alphabet from the 6th century BC.

Killers of the Flower Moon

This afternoon, Conny and I went to see the film Killers of the Flower Moon. An impressive film. Lily Gladstone, who played Mollie Kyle in the film, is not from the Osage Nation, located in Oklahoma, but is of Piegan Blackfeet, Nez Perce, and European heritage and grew up on the reservation of the Blackfeet Nation, located in Montana. I liked it that film made use of the Osage language and that not all of it was translated. I also found out that in 2006 the language was given its own script and I like it that it is actively used.

Installing Flutter on Ubuntu 22.04

Tuesday evening, I made an attempt to install Flutter on FJF4 (running Unbutu 22.04 LTS) following the instructions on Linux Installation Guide. I think I used the command:
sudo snap install flutter --classic
When I ran flutter doctor. It reported problems with the 'Android toolchain' and 'Unable to determine VS Code version'. I made some attempt to fix those problems, but got stuck. On Thursday, I decided to give it another try. I already had installed Visual Studio code some time ago. When I started, it reported that it was Version 1.84.1. I guess that it has been updated automatically recently. Visual Studio code started to download .NET, but reporting time-outs. I went to the trouble shooting page. Although I think, I will not really need .NET for Flutter, I followed the instructions on Install .NET SDK or .NET Runtime on Ubuntu 22.04. I executed the commands:
sudo apt-get install -y dotnet-sdk-7.0
dotnet --list-sdks
The last command retruned 7.0.113 [/usr/lib/dotnet/sdk]. I restarted Visual Studio Code and it still wanted to install .NET version 6.0. So, I executed the commands:
sudo apt-get install -y dotnet-sdk-6.0
dotnet --list-sdks
The last comamnd now also returned 6.0.124 [/usr/lib/dotnet/sdk]. I created a settings.json file with some paths according some instructions and restarted Visual Studio Code again. It again reported some problems, but gave me the possibility to cancel downloading. I suspect this is going to happen every time. I am always a bit surprised why it is so difficult to get such simple things correclty. Why is there some automatic mechanism to download .NET, but no simple to stop it?

I also installed Android Studio by downloading the file android-studio-2022.3.1.20-linux.tar.gz. I extracted it to my home directory and executed the command:

cd android-studio/bin
I installed the Flutter and Dart plugins. When I run flutter doctor, it still reports the same problems. It finds an Android SDK that I have installed before, but complains that the cmdline-tools component is missing. I have to run some sdkmanager command, but when I do this, I get what seems to be Python runtime error. I downloaded the file and copied it to /root/.cache/sdkmanager/ after which the command sudo sdkmanager --licenses reported: 'All SDK package licenses accepted.' The command: sudo sdkmanager --install "cmdline-tools;latest" still returns the same error.

Today, I read some more and tried to install the Android Studio. From the start page, I selected 'Customize' and then 'All settings' to open the Settings dialog. In which, under 'Languages & Frameworks' I selected 'Andriod SDK'. In the 'SDK Tools' tab, I selected 'Android SKD Command-line Tools (latest)' and some others and clicked OK, after which some components were installed. After I ran flutter doctor again, it only reported that I had to run flutter doctor --android-licenses to acknowledge the licenses. After this, it reported that the Android toolchain was installed (version 34.0.0). So, it looks I am good now following Your first Flutter app at codelab along the video Building your first Flutter App - with a Codelab!. I guess, I should have read the 'Frequently Asked Questions' section of Set up your Flutter environment a bit better. It looks like I still had to install Flutter plugins in Visual Studio Code through File -> Preferrences -> Extensions. I got Flutter v3.76.0 installed. And it seems, I can follow the tutorial just fine.

Going into the city

This afternoon, I went into the city for about two hours. I first visited Fotogalerie Objektief where I saw the exhibition Peat with photographs by Bo Scheeringa. I like the landscape picture very much, like this and this. She must have spend a lot of time outside. I paged through the book that was on sale, but I was not impressed in view of the price. Next, I went to Beeld & Aambeeld, to see the exhibition De Nieuwe Kust with photographs by Michael Rhebergen again. From there I went to Concordia. Upstairs I saw the exhibition Samenspel. I liked the drawings by Adeniji Adeoluwa, who studies physiotherapy here in Enschede. I also liked the book and installation by Nadine Klok. Downstairs the last preparations for the next exhibition, which will open tomorrow afternoon, were in progress. Finally, I went to bookshop Broekhuis to look around a bit.

Doublet #5

This afternoon, I went to the opening of the exhibition Doublet #5, a collaboration between Lisa Sebestikova and Lenneke van der Goot. Lisa creates scultures made from various materials. Some of the sculptures, I saw before this year on Sunday, May 28 at 'KunstenLandschap 2023'. Her scultures were hung above an area filled with water and ink. Lenneke decorated the walls with drawing and prints from her works, many of which are lithographs. At about 15:56, I bought the book Wandering Lines written by Arno Kramer and Richtje Reinsma, edited by Lenneke van der Goot and Welmer Keesmaat, written in Dutch and English (translated by Mari Shields), and published by Tique in 2017, ISBN:9789081850377, for € 15.00.

The Overkill Festival

This evening, I visited the Overkill festival. This year it is held at another location than last two years, which consists of one large space. This gives a different atmosphere also because the music from the music popium can be heard everywhere. There I saw the following games, films and/or installations:

This morning, this is what we got from Herenboeren Usseler Es, a farming cooperative we are members of.

What you get depends on the number of mouths you are paying for and what choice you make when there are options to select from. I brought the following home:

Counting ballots

Today, the general election was held and I went to help for counting the ballots at at polling station 675. I arrived at 20:20 and first went to vote myself. I decided to help with counting after I was an observer the last time. I had to follow some online course with a short exam. The counting of the ballots started at 21:00 and took about five hours. I did enjoy it. I did not observe any irregularities. I was the one who found the one invalled ballot. In the end all the numbers did add up. There also was one man to observe the voting. At the end, he did take pictures of the process report after all people who helped with counting, had signed it. I did not write down the number of all the votes, like I did the last time. I think, I do remember the numbers for the largest three paries: 337 votes for NSC, 174 votes for PVV and 79 (or 78) votes for VVD. I got the impression that the observer had registered himself with the (Dutch) website Alle kiezers tellen mee, which can be read in two ways, which translated as "All voters are included" or "All voters join the counting." I understand that observers can upload their pictures of the process report, but the website is not clear about what they are going to do with them. I informed them about the program that I developed and offered my help, but so far, I have not received a reply. Which does not surprise me, because some of the organisations behind the website are rather dubious, supportes of various conspiracies, like the one ran by Willem Engel. It would nor surprise if they think that they could expose election fraud, but I fear they will not be able to find any fraud.

Election results

Many people are shocked that the Party for Freedom won the elections with a landslide victory. Although in the last months, Geert Wilders, the only member (and the authorian leader) of the party, has taken a mild position, it is undeniable that the party is right-wing to far-right party. There seems to several reasons for it victory. One being that Dilan Yeşilgöz-Zegerius, the current leader of the People's Party for Freedom and Democracy, has stated at the start of the election campain that she is open to a coalition with him. Immigration has been the main theme of the campain, where many were blaming asylum seekers for all the problems in the country. Another factor is that the combination of two left-wing parties, the Labour Party and GroenLinks, under the leadership of Frank Timmermans was gaining popularity and that many right-wing parties where shouting that if he would win that it would destroy the country. Although the Bureau for Economic Policy Analysis did conclude that his economical plans were much better than those of the People's Party for Freedom and Democracy, the fearmonging that some (the very rich) would hit hard by it, appearingly was believed more than the rational facts. Most people do not realize that democracy itself is not safeguard for fascism. Populism often leads to fascism. It is a reality that many fascist and authoritarian leaders were elected in power. This makes me think about the words by Yoda saying: Fear is the path to the dark side. Fear leads to anger. Anger leads to hate. Hate leads to suffering.

Going into the city

I first went to TETEM art space. There I was told that you have to make a reservation for the new virtual reality exhibition Enter New Babylon: A Mixed Reality Installation and that it costs €10. I decided to skip it. When I went outside, at 14:27, I saw a half rainbow and I heard some rain coming, so it I thought. But when I biked away, it started to rain hail and when I looked back, I saw a complete double rainbow. I quickly put on my poncho and thought about taking a picture of it, but the rainbow was gone already. I the city, I went to Fotogalerie Objektief, where I read that it was closed because there was going to be an opening at the Grote Kerk (the large church) about the exhibition Polaroids with photographs by David van 't Veen. I decided to attent the opening. The official opening was a talk by Winnie Sorgdrager. She was once photographed by David van 't Veen. They also showed a fragment of the television program 'Mag ik van u een foto?' from the series 'Kunst op het spoor' that was broadcasted on December 7, 1980. David van 't Veen was born in 1947 and died in 2018. He attended the AKI and later became a teacher there. He was a painter, but when he got problems with his eye sight and no longer was able to paint small details, he resorted to photography with polariods because they gave the kind of soft colours that he prefered. He often made sketches that he tried to recreate with photographs.

After the opening, I went to bookshop Broekhuis where at 16:28:50, I bought the following two books:

After this, I walked to the galery and watched the exhibition. There were still a lot of people mostly talking with each other. I think I will come back another time to watch the exhibition again.

Official reports of the voting

I discovered that the official reports about last Wednesday voting are available. A copy of the official report for polling station 675 (in Enschede) is the PDF: 0153_Stembureau_675_MONTESSORIECHOOL DE WIELERBAAN_CORRIGENDUM_TK23_ZH.pdf. As far as I could see, it looks like the process report that I signed, except of course for the second half that consists of copies from the recounting that was done at the central location stating that there were no differences found. These reports do not contain the pages with signatures of all people involved in the counting of the ballots for obvious reasons. The EML files are also available.

Wet snow

This afternoon, there was some wet snow falling from the sky. At the end of the afternoon, I found some of it on my car. Still would not count this as snow.

Debugging the emulator

In the past weeks, I have continued working on the i386 emulator. I have implemented all the instructions mentioned in x86_defs.M1 (from commit e86bf7d3). The M2 now runs without reporting any unknown instructions and it seems to parse the input files, but after that it reports the first time (process 20) when it is executed:
Unknown type 
And the second time it is executed (process 25) it reports:
Unknown type 

I currently do not have a good idea what could be wrong. I am thinking about modifying the Emulator such that it generates a C(++) program of all the parts it has executed. I already have some ideas about how I could do this, but it requires some work. I could then try to debug the generated program by adding print statements and hopefully figure out what is going wrong. Before I start working on this, I have commited the current state in the commit 960d6cf4.

Wesnesday, November 29, 2023


Yesterday evening and last night it did snow. When I woke up, I only saw some patches of snow on the ground, which quickly disappeared in the morning. At the end of the afternoon, there were large flakes of snow falling from the sky, but because them temperatures were above zero Celsius, most of it melted again. In Germany there was some heavy snowfall in the past days.


At 17:40, I bought the book Forum en scène edited by Maria-Rosa Boezem (the wife of the Dutch conceptual artist Marinus Boezem), written in Dutch and published by Stichting Forum Middelburg in 1984 from charity shop Het Goed for € 1.50.
