35.0° Celsius
The temperature at Twenthe Airport has gone up to
35.0° Celsius, which breaks the record of 33.7° for this day that was
reached in 1957. This is the second tropical day where the temperature
reaches 35.0° of this year. Last Saturday, the temperature reached
26.5°, last Sunday 26.7°, and yesterday 28.6°. For tomorrow the
predicted maximum temperature is 36.0°. It depends a bit on when the cold
air, with probably a lot of rain, will arrive here.
36.9° Celsius
The temperature at Twenthe Airport has gone up to
36.9° Celsius, which breaks the record of 36.1° for this day ten years
ago and also makes it the third day this year that the temperature of 35°
is reached. Today, a national heatwave was announced, the first since September
2023, because the temperatures at the Royal Netherlands Meteorological Institute the temperatures reached
30° and with this the conditions were met, which are that the
temperature should reach 30° in a period of at least five days where
the temperature reaches 25° every day. We did not meet those criteria here.
At half past four in the afternoon, the temperature dropped 10 degree in about
half an hour. There was some intense lightning and thunder in the areas a bit
South of us and also some around us, but nothing close. We did get some rain,
the first in some weeks. I read that in a city in the area South of us, 127
case of damage through rain and wind gusts were reported.
Graduation Show at Rietveld Academie
I traveled to Amsterdam to attend the Graduation Show 2025 at Gerrit Rietveld Academie. But first I went to see the exhibition Digital Deluge at the headquarters of ABN AMRO Bank. I found the following works noteworth:
- Screensaver, Peter Struycken, 1997.
- Wednesday, April3, 2019 15:13:14 CEST, Harm van den Dorpsel, 2023.
- Wednesday, April3, 2019 12:11:23 CEST, Harm van den Dorpsel, 2022.
- Digital Deluge - Tap to Unlock, Noor Nuyten, 2024.
- #+28.05.02, Saskia Noor van Imhoff, 2017.
- Abstract Browsing 18.01.01 (Guggenheim), Rafaël Rozendaal, 2018.
- Diney (Mutant Garden Seeder), Harm van den Dorpsel, 2018.
At the Graduation show 2025, I found the works of the following
students noteworthy, which is very subjective and often based on the first
impression, in the order I encountered them:
At 16:57, I bought the book radical accessibiity: crib
pedagogies, crp theory, crp practice edited by jorinde seijdel, written
in English, and published by Studium Generale 2024-25, Gerrit Rietveld Academie
in January 2025, ISBN:9789083813883, for € 5.00.
At 17:38, I bought a ceramic cup made by Miranda Axelsson from the shop for
€ 20.00. Although it is usuable as a cup, I also consider it as an
work of art.
Graduation Show at KABK
Today, I went to the Graduation Show 2025 at KABK. I found the works of the following students noteworthy, which is
very subjective and often based on the first impression, in the order I
encountered them:
In the train, I read the book radical
accessibiity: crib pedagogies, crp theory, crp practice, which I bought
yesterday at the Gerrit Rietveld Academie. It seems that the
book was published for the Studium Generale program with the same title that was held on 19-21 March of this year. The
books seems to be a collection of (short) quotes and definitions. It was an
interesting read, but it also made me feel like you have to be rather
privelegded to be able to think about the subject. I do realized that I am that
privelegded too, but I do know people around me who are not.
Are we on the brink of World War III?
The article China tells EU it does not want to see Russia lose its war in Ukraine
starts with: 'Chinese Foreign Minister Wang Yi told the European Union's top
diplomat on Wednesday that Beijing did not want to see a Russian loss in
Ukraine because it feared the United States would then shift its whole focus to
Beijing, according to several people familiar with the exchange.' Although
China claims that it is not involved in the Russian war, parts from Chinese
companies have been found in the drones that rain down on Kyiv by the hundreds
every day on civilian building. Because they target civilian buildings to
terrorize the population, they are considered as war crimes. China seems to
side with the Russian agressor and not speak out against the state terrorism.
From the recent steps, such as withholding promised weapons deliveries, that
the USA took, one could already conclude that the USA is shifting it focus to
China. The European government leaders are speaking a lot, but rather slow in
taking actions. There are signs that Russia is preparing for a war in the
Baltic's. So, even if there is a ceasefire in Ukraine, Russia could attack
Europe again and this time also involving NATO. It would be rather strategic if
that attack would come at the same time as an attack of the People Republic of
China on the Republic of
China, also known as Taiwan. Although Trump has made the European NATO
members to increase their defence spending and is vague about whether the USA
would support them when Russia would attack a NATO country, the highest NATO
general in Europe is still an American who might act on orders given from the
USA. Although the European NATO members have large armies, I wonder if they
would be able to fight a trench war in the Baltic's due to a lack of tanks,
howitzer, ammunition, and such. European countries now already have expressed
hesitance with respect to placing peace keeping troops in Ukraine in case of a
ceasefire.
Graduation thesis
At 15:33, I received the graduation thesis The Parametric Nature of Life Systems written by Falera van Balen in English, ISBN:9789403799704, which I had bought on Monday, July 7, 2025 at 23:46 for
€ 12.67. I saw this at the KABK Graduations show on last Friday.
Old software engineer
Almost four years ago, I wrote something about
being a Senior Software Engineer. Now, I almost feel like
I have become an old software engineer. I notice that it takes me more and more
energy to learn new things. It is not only that I am wary of using AI agents for coding. In the past weeks I had to somethings with the Linux
Devicetree and I just
noticed that I barely had the energy to search for documentation, not yet
having found a single source of documentation to follow. Due to being rather
introvert, I notice that my energy depends a lot on whether the project is
appealing to me and that depends on whether the project has some positive
impact on society. I feel that somehow this no longer makes me a senior
software engineer, because for me being a senior also means not just being
experienced at writing software but also being able to organise your work and
being able to be a technical lead for the project you are working on.
AKI '25
This afternoon, I went to see the exhibition
AKI '25 at Concordia. This exhibition has a selection of the AKI Finals exhibition featuring works by the following graduates from the
AKI:
Stack_c interpreter
In the past three weeks, I have been working on an interpreter for the Stack_c programming language, which is used as an
intermediate language in the compiler, called tcc_cc, I am
writing as an replacement for the MES-compiler used in Live-bootstrap. (The initial version of this language was presented in the
article 'hello world!'.) After, I managed to
compile the tcc_cc compiler with itself on June 28, I used it to compile the Tiny C Compiler (TCC), but the resulting executable gave a segmentation fault when executed on some simple input, due to as far as I
could see a global variable assigned with a strange value. Because debugging
machine code is hard, especially if the compiler does not have the symbolic
information that the GNU
Debugger requires, I decided to start writing an interpreter for the
Stack_c language that would check on any illegal operations with memory. This
evening, I got it to work on intermediate code that was produced by running
the tcc_cc compiler of the TCC sources and it revealed a bug in the
compiler, when I executed the command:
./stack_c_interpreter tcc.sl unittest.c
The fragment it stumbled on is:
static char const ab_month_name[12][4] =
{
"Jan", "Feb", "Mar", "Apr", "May", "Jun",
"Jul", "Aug", "Sep", "Oct", "Nov", "Dec"
};
The type of ab_month_name is a bit unorthodox. Usually this is
declared as an array of pointers to character. I have noticed before that the
source of the Tiny C Compiler is not particular easy to compile. Maybe this is
on purpose to use the sources as a very large test case for the compiler
itself. I will have to do more work on the tcc_cc compiler to deal
with case.
Cuernos del Paine
This morning, I was greated with the image Cuernos del Paine in Chili as the wallpaper of the laptop I was working
on. There is a dark line on the left side of the right peak and for a moment, I
thought it might be some path to walk up the peak. I did some reseach. These
peaks are int the Torres del Paine National Park. It took me some time to figure out which
they were. I first searched for the location with Google Maps. Next I opened OpenStreetMap to the location, because I know from experience that the often do show
hiking tracks that are not displayed on Google Maps. They did show them along
the lake but nothing up to the peaks. To make sure that I had identified the
peaks correctly, I used Google Earth and found a view close to where the picture was taken. The peak on the left is
Cuerno Norte with a height of 2200m and the peak on the right is Cuerno Chico
with a height of 1380. I wondered if the peaks were climbed. I found
a page about climbing in the area. I also found a picture showing the black line on Cuerno Chico. Later I found there is
an organize trip to climb Torre Norte and a page with climbing routes. I guess I am too old to ever being able to
climb those peaks even if I would want to do so.
