Afstemming / Balance
In the afternoon, I went to see the exhibition
Afstemming / Balance
with works by Peter Struycken in andriesse eyck gallery, which has eight of his new works and four earlier
works (two from 2016 and two from 2014). The last series of works all have
twelve colour either in a twelve by twelve grid or on a twenty by twenty grid.
The colours are selected such that they are in balance with eachother with
respect to brightness and saturation. The lights in the gallery where off
because the works need to be viewed in daylight. Any other light source may
destroy the balance. It is not even possible to take pictures (with a digital
camera) of these works due to the limitations of the three colour channels of
the camera. Some colour just get out of balance destroying the effect of the
original works. I met with Peter Struycken and talked about him about the
works, most of which took more than two months to be made, and other matters.
Afterwards, I also visited galery Ron
Mandos where I saw the exhibition Lesssons of the Hour by Isaac Julien. I also visited the bookstores Boekie Woekie and Scheltema.
I wrote a script (for the MySample editor) to correct the colours in some pictures of the
Afstemming (Balance) works of Peter
Struycken. For each of these works he selected twelve colours with equal
distance hues and the same brightness and saturation. He spend a long time to
balance these at daylight conditions. When you take a picture of these works
with a digital camera the balance is lost because the blueish colour become
appear more bright and the redish/brown colour become darker. A side effect of
the balance becoming lost is that the pattern of the twelve by twelve or
twenty by twenty squares gets unintentionally the focus. The photographs of
the works and the
Afstemming / Balance exhibition were taken by Peter Tijhuis. The script converts the RGB to HSV, adapts the brightness depending on the hue, and converts it back to
RGB. The result of the correction is not perfect and probably also depends on
the colour settings of the monitor, but is hopefully a little better than the
At 16:30, I received the book Rusty Brown written by Chris Ware in
English and published by Knopf Doubleday Publishing Group in 2019,
which I had bought yesterday at 14:58 in the webshop of bookshop Scheltema for € 14.95. I had seen this book
last Saturday in the shop.

- De hobbit written by John Ronald Reuel Tolkien in Dutch published
by Uitgeverij Het Spectrum N.V. in 1971, translated by Max Schuchart from
The Hobbit, ISBN:9789027400437. My mother read this to us. There is even a tape with a
recording of this.

French with translations of certain words in Dutch in the margin and

published by Slingenberg in 1997, ISBN:9789072275455. (I have some faint memory having given this book to
my parents, because it contains a picture of De Haar Castle, which we used to visit with my family when we lived

This evening, I got my first 'real' compiler working. Actually, it is only the
first step of a compiler. The program cc1.c can be used to compile one specific program,
hex0_2.c, which can hardly be called a C program, into some
intermediate file, which with some kind of macro assembler and a program to
convert hexadecimal numbers to binary, resulting in a program, called
hex0_2 that does that: converting hexadecimal numbers to binary. In
the past weeks, I spend quite some hours debugging various versions of the
hex0_2 program with the edb debugger to fix bugs in the cc1.c program.
Rinus Roelofs: Mathematical art
I went to TkkrLab for the Cyber Saturday
presentation by Rinus Roelofs about
mathematical art. (It is about half a year ago that ago that I visited a
space.) His presentation is about folding flat shapes into 3D objects. The
oldest description is by Albrecht Dürer. Roelofs showed a number of animations based on these descriptions. He also talked about
Regular Polyhedra. He experimented with all kind of constructions of basic
shapes where all the shapes are connected with straight angles, which if made
from wood with a laser cutter can be put nicely together.
The presentation, in Dutch, but with a lot of interesting animations, was
recorded and can be found on YouTube: CyberSaturday: Mathematische kunst door Rinus Roelofs.
This morning, my mother passed away at the age
of 91. She already received end-of-life care for some days and at her age and condition it was not
very likely that she would recover from her illness. My oldest sister stayed
with her during the night taking care that she was comfortable. I am happy that
Annabel and I visited her last Tuesday for
about half an hour. She was only briefly awake and excused herself before
falling asleep again. I visited her on October 2 and had
a nice talk with her.
This morning, Conny handed in the keys of her
former home, where she lived for fourteen years. In the past months we spend a
lot of time moving things to our come and cleaning her home. Hopefully, we will
have some time for other activities, such as searching for border poles and
I went to the city to get some recent passport photo for the renewal of
my driver's license. At the shop I got another set of four of them and a medium
sized portrait photo with me smiling for free. After this, I went to
bookshop Broekhuis. There I saw the exhibition of Balance in Life with photographs by Jelle Rietveld as part of the Fotomanifestatie Enschede '21, which has the
theme: Colors of Life.
At 11:35:56, I bought Moleskin daily planner for
2022 and the book Room to Dream: A Life written by David Lynch and Kristine McKenna in English and published by Canongate Books in 2018,
ISBN:9781782118404, for € 17.95.
