Birthday

Today is my birthday, but I am not going to celebrate it with family and friends, because on August 4, I celebrated that I was 20,000 days old.

At the end of the afternoon, I went to the Imaginary exhibition in the top of the building Horst at University of Twente, which is about (the visualization of) mathematics. Quit interesting, although I did not learn much news, but it was fun to play with the tiles and make periodical and aperiodical tilings. I talked with the two math students that acted as hosts. At the end they gave me a free catalog.

Fractal Jigsaw: SVG

In the evening, I wrote a program to figure out how to the basic fractal form of the Fractal Jigsaw puzzle using SVG can be generated. Below the result showing three shapes with increasing size, using the same algorithm with more recursion:

Tetem

This afternoon, I went to ETEM art space and there I experienced and enjoyed We Are Never Ever Ever Getting Back Together, a light and sound installation by Doron Sadja, about which I cannot see much if you have not experienced it yourself. I also watched the video about the work, which, as is often the case, did not reveal much. I looked around the graphics exhibition, and as happened before when I revisit an exhibition with works from many different artists, I noticed some works that I did not remember having seen before, while I definitely must have seen them. In a corner of the reception hall, I noticed audio-DH with many wierd, but also interesting sound fragments. I found the fragment by Mariska de Groot interesting enough to listen till the end. I think about buying the physical edition.

Arrival

This evening, I went to see the movie Arrival. Quite an interesting experience. I did not find it very scarry. It would indeed be very interessing if the events as depicted in the movie would occur. It would definitely help humanity to rise above its current state. It is advicable, as usual, not to watch the trailer. I saw the trailer, but it was many months ago, so I had forgotten most of it.

AKI open day

Together with Andy, I paid a short visit to the open day of the AKI. We were greated by a cheerful student asking us whether we wanted some information about the workshops being given and offered us a drink voucher. I declined both. It was interesting to look around all the studios. We saw some students working with pots turntables. I also discovered they have some wood and metal workshops. I discovered that the rooms that are used as exhibition rooms during the final examinations, are actually in use by the students as their workrooms, and were filled with half finished works of art. I would have loved to spend some hours looking around, but Andy was dragging me around, and indication that he rather wanted to go home. At the library they were selling examination catalogues, which I have been collecting, for three Euro each or four for ten Euro. Around 12:02, I bought the following four examination catalogues for € 2.50 each:

Google translate

I used Google translate to translate a message to Chinese (Mandrin). I used the reverse translation to verify that the translation was acceptable. I had to make some changes to the English text to make the reverse translation express the same, which hopefully has made the Chinese translation more accurate. I have to admit that the reverse translation contained some improvements of my own text with respect to the use of certain expressions.

Book

At 14:41:54, I bought the book Khomeini, Sade en ik written by Abnousse Shalmani, written in Dutch, published by De Geus - Oxfam Novib in 2015, translated by Jan Versteeg from Khomeiny, Sade et moi written in French, ISBN:9789044534504, from bookshop Broekhuis for € 9.95.

Disc extract script

On November 8, there was a laser cutter workshop at TkkrLab where someone brought an image of a cardboard disk for an old music playing box, with the question whether it could be cut on the laser cutter. It turned out that it was rather hard to transform the image into a clean SVG file that could be laser cut. This was due to the poor contrast and the shadows cast by the cardboard. The music playing box is from around 1900. I found some information in the "Instrumenten Kabinet" document under number 581. I have been working on a script for the MySample editor in the mean time. (I had to make some modifications to MySample to add functions for the sine and cosine.) One of the problems proved to be to find the center of the disc. I introduced a method that searches for the optimal value searching from an initial point. I still have to add the part that generates an SVG files, but that is relatively easy, now that it can output a list of notes on each of the sixteen tracks. The script uses a one tenth degree resolution to determine the start and end of each note. Below a scaled down version of one of the result images generated by the script:

Bookshops in Utrecht

From the railway station, I walked through the streets Voor Clarenburg and Mariastraat to bookshop De Wijze Kater, which appeared to by a new age type of bookshop, which with a passage is connected to another shop selling singing bowls, incense and such. They had a whole shelf with books by Osho, which were all quite expensive. Next I went to small Stach food shop to collect a food bar that came with the city trip train ticket that I bought. I walked under the Dom Tower, and considered the option to climb it, as the sky looked quite clear and because it had been such a long time ago that I climbed it. (I remember having climbed it with Li-Xia when she was pregnant with Annabel, which was 22 years ago.) I did walk through quadrangle besides the Dom church, a place with special memories for me. Next I went to bookshop Steven Sterk, which has a lot of ramsj. I bought a small book as a present for one of my sisters. After I brought a short visit to bookshop Aleph, I visited Broese Boekverkopers. Not much has changed since the last time, I visited this bookshop more than four years ago. I did not buy any book.

Art

I visited Tetem Art spaces. Here I first watched the exhibition All is transformed, which I did not find very interesting. Next I experienced We Are Never Ever Ever Getting Back Together again. There was now a push button at the entrence to start the installation. Next I went to The Overkill Festival, but when I heard that the ticket costed 10 Euro, I immediately decided to leave, also because I did not plan to stay very long. At bookshop Broekhuis, I met with René Völker, who has an exposition of his painting at the top floor. We talked for a long time. He gets the inspiration for his painting by playing with Lego bricks. I find his works quite interesting. At last, I went to the pop-up gallery, which just opened yesterday and has works of about twenty different artists from the region. I found the following noteworthy:

Disc extract script: SVG

I extended the script from last Thursday with a procedure to produce a SVG file that gives a representation of the disc as found by the script.
