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.

Under the mask of awkwardness

I went to see the exhibition Under the mask of awkwardness by Willemijn Calis. She herself writes about the pieces shown: "People like to take control of themselves, we act as best we can, avoid and prefer what we do, but we see that less attractive aspects are tucked away or neglected, but that they can thrive in this exhibition. My light shines on unaffected moments and what is beneath the surface of our apprearance." One of the works on display is the movie: Feeling Cocky.

Artoholic

This morning, in the train, I finished reading the small book My Name is Charles Saatchi and I Am an Artoholic by Charles Saatchi, which I started reading on November 6 after I bought it on November 3. In this book he answers questions from the public. Although non of the questions are the same, many of the answers are. The book could thus even shorter and still transmit the same message. Still it was a fun book to read and that I would not have wanted to miss because of one sentense that struck me: I don't buy art in order to leave a mark or to be remembered; clutching at immortality is of zero interest of anyone sane. (Page 58.)

Utrecht

I bought some (Dutch) peanut butter, with a garlic-union taste as a present for my sister. I found a shop with a crath of Club Mate in the window sill. They costed € 3.00 each. A little too much. I visited bookshop Steven Sterk. At 13:54, I bought the book Stedelijk Collectie Highlights written by Hanneke de Man, Frederique Huygen, Timo de Rijk, Angela Bartholomew, Elvie Casteleijn, and Karolien Buurman in Dutch and published by Stedelijk Museum Amsterdam / nai010 uitgevers in 2012, ISBN:978462080249, for € 7.90. I also went to visited bookshop Broese.

469410 solutions

Finally, tonight the program processing the 428,362 sets of equations has finished, finding a total of 469410 solutions. I say program, but I should say programs, because I made several modification, including two multi-threading versions (for windows and linux). I have not yet verified that all sets of equations have been processed. I also have not yet verified the solutions (a second time), nor have I done any further analyses. If I am not mistaken, the smalles solution is:

42 49 62 75 89 92 97 99 100 118 120 125 127 128 132 134 148 152 153 155 160 163

Physical Digital

At 15:00 was the opening of the exhibition Physical Digital on the second floor at Concordia. The exhibition is related to the Overkill Festival. The art works on display have a relationship with gaming. Starting from right, there is a VR installation with an imaginary world by pussyKrew. Next a projection of a Cellular Forms movie by Andy Lomas, which shows white spheres forming all kind of shapes. The number of spheres are multiplying and becoming smaller, sometimes producing very organic forms. On the next wall there is a game by Ian MacLarty that allows you to walk through a kind of landscape with a game controller. The landscapes sometimes morphes into a different landscape. Next there is projection of the movie Pandemonium by PWR, which is hard to describe. In the middle of the room there is a large green grass-like carpet with balls and other objects. There are also two monitors showing Still Life by Mike Pelletier.

Phosho18

In the evening, I went to see the exhibition Phosho18 at B93 with pictures by some students from Saxion. I liked the pictures by Ana-Maria Mihai with she titled Blocks from Constanța. She also handed out some clever made booklet with almost all of the pictures. I also liked the levitating welder by Mirre Rensen. The other students were Cage Spence, Kristin Dimitrova, Vasil Dimitrov, and Shtilyan Peev.

18.1° Celsius

It was a rather warm day with a maximum temperature of 18.1° Celsius at Twente Airport. I do not know if it was a local record, but in center of the country, in De Bilt, the temperature reached 19° Celsius, which is a record high temperature for November.

Hack42-on-tour

This morning, I went to TkkrLab to meet the people on the Hack42-on-tour, a two day road-trip visiting all maker/hacker spaces 33 of them. We had put some candy on the tables. Most of them also went to have a look at our workshop room, which is on the other side of the building. One of our members joined them on the tour.

Testing Pluggy McPlugface

This afternoon, I tested the Pluggy McPlugface PS2 interface for the Gigatron computer that I received earlier this week and soldered together yesterday. I had some problems with the power supply before I got it to work. Seems that the best approach is to plug in the PS2 keyboard after the Gigatron had started. I loaded the Basic interpretter from the microcontroller on the Pluggy McPlugface and played a little with it. Later, I replaced the Version 1.0 ROM with the Version 3 ROM and played the Tetronis game and got a highscore of 10175. This new ROM is really an improvement turning the Gigatron in a little home computer with Tiny BASIC.

Going into the city

I first went to Eye Wish and decided to pick a new pair of glasses for the 'reading' glasses that I had selected some time ago. This means that I will be carrying around four pairs of glasses. My old glasses, which I mainly use when I go to see a movie, a pair of sun glasses, my current glasses which have a +1.25 dioptre correction, and the new pair of glasses, intended to be used while sitting behind a computer, which have a +1.75 dioptre correction. Next, I went to bookshop Broekhuis, where at 13:43, I bought a Moleskine plain notebook with a black, hard cover, which I am going to use as my new personal diary, when my current personal diary is going to be full. At photo gallery Objektief, I saw the exhibition Ida - Reines with photographs by Jelle Pieter de Boer. I went to TkkrLab and soldered the PS2 connector for the Gigatron computer. I was not totally satisfied, because after I soldered the PS2 connector, I discovered that it was not really straight as it should have been. I went back to Eye Wish to get my new glasses. In the evening, Annabel and I made jiaozi and we watched the AlphaGo movie on Netflix. We both found it very interesting to watch. Although, I did follow it in detail and new the outcome of the match, I still found it exciting to watch. The movie does not focus on the details of the game, but on the people involved and their emotions. It shows a lot of what went on behind the scenes.

Parallel parsing with processes

I got the idea to apply the ideas given in Machine independent implementation of Cooperative Multi-threading in C to parallel parsing. Each alternative in a parsing rule can be viewed as a seperate process that stops at characters to be processed. In case a rule contains a non-terminal, this means that a subprocess needs to be started. There are actual two ways to implement this, based whether one want to start with the elementary grammar rules or use the extended grammar rules. In the extended grammar rules keywords are used to describe optional, sequential and grouping of grammar symbols, for which one otherwise would have had to introduce separate non-terminals, often resulting in a large number of non-terminals and passing of intermediate results. A better approach seems to have one function per non-terminal (for the extended grammar rules) and clone the data structure for each variant. I still have to work-out all the details. Maybe some kind of preprocessor would be handy with respect to all the book keeping with respect to label names for the goto statements.

Last summer day

Today, the temperature reached 25.2°C at the weather station Twenthe. It seems it will be the last summer day (a day on which the temperature reaches 25 degrees Celsius) of this year. So far, we have 75 such days, with 16 days where the temperature reached 30 degrees. The highest temperature measured this year at the weather station is 36.2°C. This also is the record temperature since measurements started in 1951.

Funeral of Li-Xia

The funeral service for Li-Xia started at 9:30 (in the morning) at the crematorium in Usselo. We only invited family and friends (of Li-Xia) who had taken the effort to visit her in the carehome where she stayed in the past years. Of course, Annabel, Andy, and my mother were present. And also our long time friends Bert and Cornelise. Because, Li-Xia's family could not be present, a recording was made of the service. We asked a professional photographer to take picture before, during and after the service.

Afternoon

Because of the extreme warm temperature of the last days (Wednesday 24.1°C, Thursday 24.2°C, Friday 24°C, Saturday 27.7°C, Sunday 25.8°C, and today 24.4°C), I decided to get an icecream in the center of the city. I continued to TETEM art space, where I saw the exhibition Do It Together Neighborhood (for the first time) and Bits, bots and brains (again). From the last exhibition, I liked the works drawⁿ by Maria Smigielska and Les Colchiques by Pierre Cutellic.

At 17:38, I bought the book Duin messias (the Dutch translation by M.K. Stuyter SJ of the English Dune Messiah), written by Frank Herbert, published by Meulenhoff in 1986, ISBN:9029008857, from charity shop Het Goed for € 1.95.
