I accompanied Andy on the Dier Day Rally
(Animal Day
Rally) with Volkswagen Beetle and Citroën 2CV (in the Netherlands nicknamed '(ugly) duck') cars. We
were traveling in a 2CV which had been galvanized, the only durable solution
to rust. The 2CV is a very minimalistic car, to keep them cheap, but now that they have become
rare, the have become worth more.
I finished reading the book Bowie's Books: The
Hundred Literary Heroes Who Changed His Life by John O'Connell, which I
started reading on September 27 after I bought it on August 22. I found this an interesting book. It is not just about the
books, but also gives biographical information about David Bowie. There are also some obscure books on this list.
At Fotogalerie Objektief, I saw the exhibitionOn the Road by Bert Teunissen.
I went to bookshop Broekhuis where I was met
with a lot of parents with their children, some of which appeared not have been
in the bookshop for a long time. This was due to the childrens book week, where
you get a free book when you spend € 12.50 on children books.
At 15:37:01, I bought the book Dagboek 1972 written by
Jan Wolkers in Dutch
and published by De Bezige Bij in 2007,
ISBN:9789023425342, from for € 9.95.
This weekend, I had a look at the book Grid Index, which I received on
Saturday, April 2, 2022 and which started me
thinking about irregular grids of squares and
equilateral triangles. I wanted to see if I could match the grids shown in
the book, with the grids by the program irst.cpp that I wrote before
and wrote about for the last time on Thursday,
August 18. I quickly found an example of a grid, gi-st-004, that
is not generated by the program. I decided to create a separate page about matching the grids with the results of the program.
I finished reading the book Do Androids Dream of Electric Sheep? by Philip K. Dick, which I started reading on October 12 after I bought it on
September 14. I found this book quite interesting
and enjoyed reading it. The book is deeper than the film Blade Runner,
which based on this book.
I was wrong about what I wrote that gi-st-004 was not found by the
program for finding regular irregular grids of
squares and equilateral triangles, because it was. But I did find that
gi-dt-005 was not generated the program. I spend some time finding
the reason for this. It had to do with the method I used to limit the search
space for patterns. I had put a limit on the lines between the rows of
possible pieces such that each can only occur once in each of the directions.
When I changed this to a restriction on the rows of the possible pieces in
the program, the missing pattern was
generated. (It has been added to the dedicated
page.) I am not sure if now all possible patterns are generated.
I went to Amsterdam to attend the PhD defense of Silke Hoppe where she defended
her thesis Our whole house has Alzheimer's. How early-onset dementia shapes
relationships of families in the Netherlands. It was held in
Agnietenkapel
(Announcement in Dutch). I took a copy of the defense at the entrance.
The recording of the defense including an introduction. The introduction
brought back some of my own experience when we were a family with Alzheimer's.
It made me also realize how I have dealt with and overcome those experiences
and also how they shaped my personal development. I think that practicing some
forms of active meditation and practice mantra singing (around 2016 to 2018)
has been a part of this.
The temperature at Twenthe Airport has gone up to
22.1° Celsius, which breaks the previous record of 21.3° on this date
in 2005. At the end of the afternoon, Conny and
I made a walked just in our shirts.
