I write, therefore I am

With this variation on a famous statement by the philosopher Descartes, I would like to express that the act of writing about what happens in my life is important to me.

Chestnuts

Between 18:10 and 18:14, I picked seven chestnuts from the tree before the Chinese restaurant at the Haaksbergerstraat. These were all small and some very small chestnuts. I did see some shells for larger chestnuts, so I guess that the chestnuts belonging to those have been picked by others. The weather has been quite warm for the time of the year, about four degrees Celsius above average, with last week even two days with temperatures above 30° Celsius. In away if feels strange to find nuts, because if still feels like summer.

TETEM

In the afternoon, I visited TETEM art space. I first watched the Special Treats Street Special exhibition with works by J&B. I stepped inside Alone with my thoughts. Next I watched the video 7 Days of Artificial Intelligence again. It was the last day of the Tribute to Remko Scha exhibition. I watched the documentary Huge Harry about Institute of Artificial Art Amsterdam.

Gogbot

This year the theme of Gogbot is Post Singularity. The interaction with technology seems to be a little absent this year. There is a zombie area, but I am not sure what is the relationship with the theme, only that the super intelligence that may arise during the singularity may view us humans as zombies. Yesterday, I already saw ANIMA by Nick Verstand in an almost completely dark Oude Kerk (Old Church) in Enschede, but I was not really impressed by it. Today, I first had a look at the exhibition at Concordia. There I saw a work by Nastia Cistakova, who won the Blink Youngblood contest, but I am not very impressed by her work. I also saw some pictures by Luuk van den Berg. Upstairs, I looked at some of the video exposition Hotel Europa. I watched there and here 2 by Ink Agop. Downstair, I also looked at the exhibition of Christie van der Haak. Next I went to Tetem, where I saw three works by Bjorn Gort that I found interesting. Willem Kempers had three works with crossing moving lines (made by LED's). I also watched the various short videos by Karina Zavidova. Also watched the short video 7 Days of Artificial Intelligence by Pierre Roquet with fragments of science fiction films telling how a superintelligence 'Deepmind' takes over the world in seven days.

Carte Blanche – Carina Schüring

This evening, I went to attend Carte Blanche – Carina Schüring with new works by Carina. There were also some old works that I saw in Almelo earlier this year. She had brought her tea with her and I made some green tea, which I enjoyed very much. She had a very interesting drawing. I also bought the book Stadschatten: Jule und ein Herz voll Licht written by Sabine Kohlert with illustrations by Carina for € 12.90. It is written in German and published by Plettenberg : TUSSNAT Pictures in 2016, ISBN:9783000537400.

Komputerstrukturen 1a and 3a

Recently, someone send me a picture of Komputerstrukturen 1a by Peter Struycken, which allowed me to analyse it. From this I found that compared with the design, the work has the following differences:
  • Row 6, column 15: changed black to white.
  • Row 23, column 3: changed black to white.
  • Row 24, column 20: changed white to black.
Long ago, I already established that the reproductions in P. Struycken komputerstrukturen and all following publications, contained following six differences. Non of the differences matches with the differences between the design and the work, again strongly suggesting that the reproduction is based on the design instead of the actual work.

On July 11, I drew a similar conclusiong with respect to Komputerstrukturen 3a. On August 3, we encountered a picture of this work. From this I found that the work does not contain additional anomalies compared to the three that I reported earlier. In this picture the work is oriented in the same way as in the exhibitions komputerstrukturen and P. Struycken, while in most publications it is rotated clock-wise by 90°, which was the orientation that a based earlier analyses on. Taking into account this new orientation, the work has the following three anomalies:

  • Either row 47, column 4 or row 48, column 4 should have been black.
  • Row 22, column 50 should have been white, like in the design AB15701.
  • Quite likely Row 44, column 50 should have been white. On the design one can distinguis the Dutch word "fout" (with means: "error") on the side with line to the square. It appears this was overlooked when the work was made based on the drawing.
The reproduction in P. Struycken komputerstrukturen seems to be based on the design AB15701, because it does not have the difference found between the design and the work. It has a total of eleven differences with the work. These are:
  • Row 5, column 23: changed white to black.
  • Row 6, column 2: changed black to white.
  • Row 8, column 29: changed white to black.
  • Row 12, column 10: changed black to white.
  • Row 19, column 20: changed white to black.
  • Row 20, column 20: changed black to white.
  • Row 22, column 50: changed black to white.
  • Row 33, column 8: changed white to black.
  • Row 44, column 44: changed white to black.
  • Row 44, column 48: changed black to white.
  • Row 46, column 48: changed white to black.

Amsterdam

In the morning, I visited FOAM: Fotografiemuseum Amsterdam to see the exhibition about Helmut Newton. I also watched (about two thirds) of the documentary Helmut by June. I was also impressed by the works Vivian Atlantis by Carlijn Jacobs. At 11:32, I bought the book Helmut Newton: Private Property written by Helmut Newton in English published by Schirmer's Visual Library in 1989, ISBN:9783888143915, for € 7.95.

I had lunch at Si-Chuan restuarant with a friend that I had not see for 35 years. Roughly between two and four, I spend at Scheltema, but I did not buy anything.

Around half four, I arrived at gallery andriesse & eyck for the exhibition Dutch Concert with works by Peter Struycken and his good friend Carel Blotkamp, who had some works based on works by Peter Struycken. Besides the new works, there were also a number works from the SHFT serie on display. I talked with several people and took pictures of all the works. I also met with Ton, Meindert and his partner. Afterwards we had dinner at Spanjer en van Twist.

Impatiens glandulifera

I already had suspected that one of the seeds of an impatiens glandulifera that I had put in the garden two years ago, some time after I found the plant on August 18, had started to grow, but now I know for sure, when I saw that it had produced a flower. The plant did not look very healhty and immediately I gave it some water. Here on the top right a picture. This is know to be a one year plant and I was a little surprised to see it, because it is two years ago that I planted the seeds and did not know that it could survive so long. I do not know if it will produce seeds, because I guess that the flower needs to be pollinated and I am not aware of other plants in the neighbourhood.

Parallel parser improved

Since I wrote about a parallel parser on 9th, I have been working on fixing problems with memory deallocation. I soon realized that not all parse state representing objects were deleted, as soon as they no longer could be reached, and that actually most of them were not deleted at all. Although this does not show in the output of the first published implementation, I do find it an essential requirement, especially when the purpose of the algorithm is to be used to parse lines in an editor over and over again, causing the memory footprint to grow with every keystroke. In the process the code has been changed considerable. The current version also contains a lot of tracing code, because it took me quite a lot of time to figure out what was going wrong and how to fix it. The idea is to integrate this prototype with the existing IParse implementation.

Zomergo: Last day

In the morning, I played against a young girl. I had to give her nine stones ahead. At first it seemed that she was going to make a lot of territorium in the center, but soon, I was sure of victory, but I did not want her to lose big, so I made many 'stupid' moves, and allowed her to close some place where I could invade. Nevertheless, she still lost with about seventy points. Afterwards, we played another 'teaching' game on a thirteen by thirteen with five stones ahead, and with my suggestions, she easily won that game.

The Green Cathedral

In the afternoon, I visited The Green Cathedral, a landscape artwork by Marinus Boezem. I walked around and through it, and took some pictures. The GPS-track of how I traveled today in KML file for Google Earth or in Google Maps

Zomergo: Fifth day

In the morning, I played against young man and and lost the game with nine and half points. From the start of the game, I felt uncomfortable about it. Half way, I thought about resigning, but still continues. My oponent suggested that I could still invade some corner. Because I had not seen this myself, I did not feel comfortable trying it. He felt that I regain some of my loss towards the end of the game.

In the afternoon, I helped with preparing the dinner. In the evening, there was a rather clear sky and with relatively less light polution, one could see many stars. We walked to a nearby field where it was darker. We could see (part of) the milky way.

Zomergo: Fourth day

In the morning, I played against woman and and won the game with nine and half points. I also worked on perfecting a short script for MySample to extract the state of a Go board from a 190 by 190 pixel image. The output of the script is used to display the Go board position at the end of my games.

Zomergo: Third day

In the morning, I played against man and and won the game with a slim margin. In the afternoon, I gave my talk about Nim, Go, and surreal numbers to about eight people.

Zomergo: Second day

In the morning, I played against a young woman, who just in the past year learned playing Go, but appeared stronger than me. It seems she is much better at reading than I, after I made a daring move (one that should not work) she was able to capture a number of stones, after which defeat was eminent. In the afternoon, I helped with preparing dinner for about four hours gutting vegitables.

Zomergo

In the afternoon, I arrived at Zomra rather relaxed Go retreat. I was of the first to arrive. The first tournament round was held in the afternoon. I won by resignation. On the right top the state of the board at the end of the game. Dinner was quite late, as usual. Afterwards some girls wanted to program the game snake on the IJduino. One of them had some experience with programming and we succeeded in implementing it using the potentiometer, which adds an additional constraint, because you cannot turn left (or right) too often in a row, because you cannot turn the potentiometer in one direction indefinitly. (The snake.ino program.)
