Het Zwaard van Radch

I finished reading the book Het Zwaard van Radch, the Dutch translation of Ancillary Sword by Ann Lecki, which I start reading last Friday after I bought it on last Thursday. By the fact that I finished the book in such a short time, it is clear that the book did captivate me. But it was also a lot because I wanted to know how the plot developed into something dramatic. The middle part had a lot of relational type of contents and felt kind like a detective. (Somehow the main character, Breq, made me think of Vera Stanhopefrom the TV series Vera.) Then at the end there was suddenly some dramatic action. Know I want to read the first book of the series.

Folding a circle into a triangle

This evening, I was playing with the round paper cover of an icecream, trying to fold it into a triangle and I noticed that the three folded parts came together at the same point. In a sense, did not surprise me, as I knew the triangle has many so called centers. (There is even an encyclopedia of it.) However, I have not been able to find the given center. Below an animation of folding the black circle into a red triangle and the grey circles representing the folded parts crossing at the same point.

At 16:50, I bought the following two books from charity shop Het Goed:

Ancillary Justice

I finished reading the book Ancillary Justice by Ann Leckie, which I started reading on last Saturday when I received it. Because I had already read the second book of the Imperial Radch trilogy, I knew some things that were going to happen. However, I really wanted to know how things played out and that was one of the reasons to finish the book in a short time. I have to admit that at some points I found it hard to put the book down. It is a good story, but there are some things that I find hard to believe. For example, how can an ancillary controlled by an AI in a ship, when disconnected, have all the knowledge and the intelligence of the AI and not simply 'shut-down' and become passive.

Rijksmuseum Twenthe

This afternoon, Conny and I went to Rijksmuseum Twenthe. We first saw the exhibition Sottobosco with works by Elspeth Diederix. Later we also visited the garden at the back of the museum that she designed. I found the following works noteworthy:

Next we went to see the gold and silver coins from the sixth century that were found in Springendal, a valey near Tubbergen. We also paid a short visit to Tolerance Test by Charlotte Schleiffert, because one of the voices was very hard to hear.

Next we saw the exhibition So Future (RMT x GOGBOT), which is going to be part of the GOGBOT festival this September. There we saw the following exhibits:

At 15:22, I bought the book A Critical History of Media Art in the Netherlands written by Marga van Mechelen and Sanneke Huisman in English and published by Jap Sam Books in November 2019, ISBN:9789492852144, from the museum bookshop for € 39.95. Conny also bought a book and we bought two Lovi wooden creations: the Lovi Star and the pink Lovi Dragongly.

32.1° Celsius

The temperature at Twenthe Airport has gone up to 32.1° Celsius, which breaks the previous record of 28.7° on this date in 1973. Yesterday, it was the first National heat wave of this year, which started on August 8.

Grid visualization

In the past weeks, since July 11, I have been wrestling with the visialization of regular grids of squares and equilateral triangles. Below the visualization of some of the grids that according to the algoritm I implemented before are unique. However, they are not all unique, which means I have to look into that algorithm again. Look for the patterns with the code: 2 2 2 2 4 1 0.

MySample on Ubuntu 22.04

Yesterday, I upgraded my Ubuntu 20.04 to Ubuntu 22.04 on my laptop FJF4 and when I started my MySample editor using Wine (as it is a Windows MFC application) it was not using the system fixed space font but some variable sized font, which simply makes it unusable because it assumes that the font is fixed. I remember having had this trouble before and I spend a long time finding out how to solve it. This evening, I installed PlayOnLinux. That also did not solve the problem until I tried another version of Wine, namely "wine-7.9". (The 'Ubuntu' version is "wine-6.0.3 (Ubuntu 6.0.3~repack-1)", which looks like a much older version of Wine.) It looks a little different, maybe because it uses different system colours, which I might be able to fix. But at least I can use it again. I am still thinking about whether I should install the latest stable version of Wine from WineHQ because that is version 7.0.

Unique patterns

Yesterevening when I was brushing my teeth, I got an idea what could be wrong with the algorithm to determine unique regular grids of squares and equilateral triangles. This evening, I implemented a fix in irst.cpp and it seemed to work after I a quick visual inspection of all the patterns.

This afternoon, Conny and I went walking in the hamlet Twekkelo not far from were we live. This is the second time we walked there and just like the first time we parked near the small Johanneskerk (Church of St. John). We followed the green walking route with two small detours. The route consist mostly of walking trails through the fields. Some trails are even along the edge of farming fields. At some parts it looked we were the first to walk the trail for some weeks. I understand that some of the trails were only established in the past three decades. We also came across a stone with the text 'Twekkelo Marke 2018' on it. But because it is in the middle of what used to be the marke it is not a marke stone.

At 17:29:24, I bought the book Bowie's Books: The Hundred Literary Heroes Who Changed His Life written by John O'Connell with illustrations by Luis Paadin, written in English and published by Bloomsbury Publishing in 2021, ISBN:9781526605818, from bookshop Broekhuis for € 9.95. In 2013, David Bowie posted a list of his top 100 favorite reads on his Facebook page. This books is about the 100 books mentioned on this list.

30.6° Celsius

The temperature at Twenthe Airport has gone up to 30.6° Celsius, which breaks the previous record of 29.3° on this date in 1955.

Irregular grids

I made some implementation for generating irregular grids of squares and equilateral triangles which can be seen below. This is not yet a proof that it it possible to create infinite irregular grids using this method. On April 6, I already showed that there is a method to create infinite irregular grids for each infinte square grid filled with two values.

32.3° Celsius

The temperature at Twenthe Airport has gone up to 32.3° Celsius, which breaks the previous record of 31.0° on this date in 2016.

Local heat wave

The temperature at Twenthe Airport has gone up to 32.7° Celsius touches the record of on this date from 2016. It is also the third day the temperatures went above 30°C and because since last Friday the temperature went above 25°C every day, it means we have a local heatwave according to the Dutch rules.

I am Spock

I finished reading the book I am Spock by Leonard Nimoy, which I started reading on July 19 after I bought it on July 9. An interesting book to read, but as some point I felt it was a bit too much an enumeration of trivia facts. I understand that Nimoy choose this title because he received a lot of criticism about the title of his previous book that was called I am not Spock. Everywhere in the book there are fragments of internal dialog between 'Spock' and 'Nimoy'. But having internal dialog with a fictive character does not make yourself that character. I presume that Nimoy, although he strongly identifies with the fictive character Spock, does mean with the title of the book, that he is very much like Spock. Maybe there are people who are more like Spock than Nimoy because I wonder if he has a very Spock like personality seeing what he has achieved as an actor and a director.

Hummingbird hawk-moth

Just before four in the afternoon, there was a Hummingbird hawk-moth in our back garden visiting our butterfly-bush (Buddleja davidii). We had never seen one before. I took three pictures, where the image below is taken from one of them.
