Marke stone and border poles
Conny gave me the book Landscape
Photography with text and photographs by Saskia Boelsums and published by Terra Uitgeverij in 2019,
ISBN:9789089898104, for my birthday. We saw some of her photographs at the
Drents Museum on July 29.
In the morning, when the weather was still a bit sunny, and we took the car to
search for some marke stones and border poles.
We first went to search for the Fabbelhuttensteen marke stone, which we could
not find on August 3. Now that the corn has
been harvest, it was easy to find. Next we searched for the border pole near
the Grenzweg in Gronau. We walked past it on May 31. At 11:20 we found the border pole 845-Y. We saw pole 845-X again. We drove to Arendsweg. There
we walked along the border towards the south. We walked along pole 840-G,
which we found on May 21 and found
hoped to find another pole, but we did not. We also followed some other path
between fields with cows in the direction of the border, but it ended before
reaching the border.
Palindrome date (DD-MM-YY and YY.MM.DD)
Today is a palindrome date when written
according to the DD-MM-YY format: 02-11-20 and the YY.MM.DD formats: 20-11-02.
The previous such date was November 21, 2012 and
the next will be November 12, 2021. This is the sixth special date of this year.
Last night the temperature did not drop below
16.7°C (at the weather station of Airport Twente) and around seven in the
morning, the old record of 18.1°C of highest temperature on this day in
1968 was already broken. In the early afternoon, the record temperature of
19.4°C was reached.
Walking in Twekkelo
Conny and I went walking in Twekkelo around the road Zwartevenneweg and the road Grote Esweg. We both
had not walked around and were a little surpriced by the number of cars on the
parking lot near the entrance of the area. We had come by bike. In the area
also the marke stone called 'Steen op
Christinalust' can be found, which marks the border between the marke Usselo
and Twekkelo. When walking around the area, we found many different types
of mushrooms and fungi, some of which we had not seen before.
Today, Conny and I went searching for the
marke stone known as Broekheurnerpaal, which is
on the border of the former marke Buurse and Usselo, which now is the border of
the townships Haaksbergen and Enschede. We discovered that it could be reached
by walking along a channeled brook. We found it around 12:09. We continued
walking along the brook, but decided to return about half way to the next road.
We saw three deer walking in the fields. They came towards us, but changed
course when they became aware of us. They jumped over the brook a few hunderd
meter from us and dissapeared in the fields. A little further we noticed that
the field was covered with cobwebs that was slowly dancing in the little wind
Four marke linden tree
Conny and I went searching for some
marke stones. First, we visited the border
between the townships Haaksbergen and Enschede on the main road connecting the
two cities. There we located the Goorpaal, a replica, which was placed on
September 19, 2020 on a slightly different location from the original stone
that was placed around 1825 at the border of the marke Haaksbergen en
Honesch and the marke Usselo. Next we went to the water treatment
area called Kristalbad, which is located between Enschede and Hengelo and is
filled with effluent from the wastewater treatement plant of Enschede. The
border of the marke Twekkelo and the marke Groot Driene crosses through the
Kristalbad. The border can easily be recogned from aerial pictures. On one of
the (inaccessible) islands there is an original marke stone, known as
Koekoeksteen. After having walked around the area, we went to University of Twente where we looked at the marke stone known as 'Steen
tussen het Driener en Twekkelerveld'. We drove a little further and parked the
car on a road called 'De Achterhorst' near some houses of employees of the
university. We walked along a path at the border where we found another marke
stone called 'Steen aan het hooiland van Van Heek' to arrive at the tree (a
lime tree) at the cross point of the four marke Groot Driene, Twekkelo, Esmarke
and Lonneker, called Viermarkenlinde, which translate as four marke
linden tree. Not far from
this tree, there is another marke stone, called 'Paal op het erf
van Helmich van Heek', but it is on private property and thus not accessible.
We walked around the area, including the Abraham Ledeboer park (which has a
one of the highest sequoiadendron giganteum trees in the Netherlands) and
ended up encircling the marke stone.
At 17:30, I bought the book Topografische atlas van
Drenthe written by Thomas Termeulen in Dutch and published by De
Vrije Uitgevers in 2015, ISBN:9789077350805, from charity shop Het Goed
for € 2.50. Although it is called an atlas, it is actually the
loose-leaf edition, consisting of 104 maps (printed double sided), with
references to each other.
Since reading about MyNOR, I have been
thinking about whether it would be possible to create a CPU from a SRAM IC
(like for example, AS7C1026B). Olivier Bailleux build
a CPU from EPROMS.
Of course, the contents of the ram should be initialized first. Probably some
kind of counter is needed and also some latches. The idea is to keep the
number of components as small as possible.
Starting from 19.00, we watched the opening of Overkill
Festival, which this year is an online edition. Before we already opened
the Festival Box and checked its contents. After the opening, we looked at
the online exhibition and got
hooked on Realness - Intimate garden
by Sandrine Deumier (after
we watched Pest to Power
by Natasha Tontey). There was no sound (or
very little) with the life coding music event. We looked around the online
exhibition and watched: Mélas de Saturne by Josèfa Ntjam. We also stumbled on the 'hidden' room with the
AKI expo. I found the
Bon Voyage by Andrea Ballestra interesting.
I the past week, I have worked some time on a template script library,
Templ_script, which I
developed last year as part of an open source library. I found myself bumping
against similar design decisions that I also encounter while working on
ParParser. Both are
programs written in C using a similar coding style. I searching for methods to
separate the essence of an algorithm from its implementation, or at least to
have some mechanism to easily modify parts of an implementation. Templ_script
itself is intended for code generation. (One of the nice features is that it
has a built-in debugger that allows you to break on any position in the
generated output. Another feature is that uses lazy evaluation for string
generation.) Although it can be used for code generation, it does not cover all
aspects of code generation. I have been pondering about the idea of a code
generator that 'understands' the semantic properties of the target language
and, for example, can help with the generation of variable names based on
knownledge of variable contexts.)
In the evening, we watched the film Little Joe, which was shown as part the Overkill Festival. Before the film
there was a Jitsi video call during which we had to create a flower using
materials found in the Festival Box. Afterwards, we watched the BBB_ performance
Songs of Cyborgoise.
