No Input Mixing

In the past weeks, I have been experimenting a bit with No Input Mixing with the Phonic MR 1843X mixer I bought on Sunday, May 14. Today, I went to buy a second-hand Behringer UFO202, a USB device for recording sound, for € 15.00. At home, I used a cable that I bought Tuesday from charity shop Het Goed for € 1.99 to connect it to the mixer and made my first recording which I also uploaded to SoundCloud under the name 20230601 No Input Mixing Experiment. The second half has some more variation than the first half. With no input mixing there is no straight forward way of changing the sound. Every knob could have an effect on the sound sometimes dramatically changing it. On one hand that makes it interesting, but on the other hand it makes it hard to create an interesting recording. Some times it creates complex sounds which can completely be gone when you turn one nob just the slightest bit.

The Guardians of the Galaxy: Vol. 3

This afternoon, Conny and I went to see the movie Guardians of the Galaxy Vol. 3 at Kinepolis as 15:45 in room 7. Conny was in chair C-8 and I was in chair C-7. I feel that the second part of the movie makes the movie.

30.2° Celsius

The temperature at Twenthe Airport has gone up to 30.2° Celsius, which breaks the previous record of 30.0° on this date in 1966. This is also the first tropical day (according to the definition for the Netherlands.) I am more worried about that we did not have any rain for almost a month (except for a few drops not even enough to wet the ground). This might be related to the fact that the wind has predominalty coming from the North. Also in the rest of the world, all kinds of records are broken:

29.7° Celsius

The temperature at Twenthe Airport has gone up to 29.7° Celsius, which breaks the previous record of 29.2° on this date in 2006.


At 17:41, I bought the following two books from charity shop Het Goed:

LISP implemented in Brainf***

The search enging Marginalia, an independent DIY search engine that focuses on non-commercial content, has an option to search for website similar to yours. I did seach for my own website. It came up with a lot of websites about LISP. I found the home page Sylwester who 'wrote' an interpreter for (a rather limited version of) LISP using Brainf***. Actually, he did not write it in Brainf*** but in EBF: A self hosting Extended brainfuck to pure brainfuck compiler. To use it, you have to compile itself with itself, which is not possible. When he developed it, he wrote it in versions of the language that incorporated more and more features of the language. The GitHub repository westerp/ebf-compiler contains a Makefile that has all the steps to arrive at a Brainf*** program that implements the EBF compiler (using a Brainf*** interpreter) and that be used to evaluate LISP expressions. An interesting find, because I have been thinking about writing a LISP interpreter using an extension of Brainf*** with some additional command for allocating memory and use this LISP interpreter to write a compiler for a subset of C.

Team outing

In the afternoon we went on a team outing with ten people from the software development team. We made a caoing trip from Quendord to Engden over the Vechte. We were given four Tahe Yuma canoes, which have three seats, meaning that two canoes had to take three people and two canoes two. I was in a canoe with one other colleague, he on the back seat, I in the front seat leaving the middle seat empty. The trip was about 7 km and took us about two and half hour. There were some rapids (three larger) along the trip and we also had some breaks on the way to eat some food that we had brought. The fastest my colleague and I went, according to his GPS tracker, was 8.5Km/h, At the end of the canoe trip, we got them out of the water and biked back to the starting point with some bikes that were provided.

Farming cooperative Usseler Es

This morning, I went to an information session organized by Herenboeren Usseler Es, a farming cooperative on the Usseler Es for sustainable food production. The Dutch (Low Saxion) word 'es' or 'esch' is used to indicate an arable area that is slightly elevated. The Usseler Es is the largest one known in Europe and for that reason rather unique. It is surrounded by a number of farms and thus a kind of angerdorf. It is likely that the Usseler Es has been in use for farming for about a thousand years. In the past thirty years it primarily has been used for growing silage maize, which is used to feed cows. The municipality of Enschede has had plans in the past to turn the Usseler Es into an industrial estate. There was a lot of opposition against this and on October 17, 2001 the municipality held a referendum about it. In the end the municipality decided to abonden this idea, also because there was no more need for industrial estate. About two years ago, the municipality decided that the Usseler Es should be dedicated to sustainable and nature-inclusive agriculture, greenery and nature. The Herenboeren Usseler Es fits in this perfectly and that is also one of the reasons why they were granted the right to lease about 20 hectares of the Usseler Es. In the afternoon, I enlisted myself as a member of the cooperative. There is no obligation to be actively help with the farming, but I plan to help out. It is about nine minutes biking from where we live.

Some rain

This evening, around 18:25, we had some rain. The last time it really rained was May 12. We did have some drops once, but that was not enough to wet the whole ground. The table in the guarden now looks wet, but most of the rain on the pavement already has dried up. We have gone for 35 days without any substantial rain, one of the longest periods on record.

In the evening, a bit after eight, it started to rain. First a bit, but later some steady rain. Not as much as in other parts of the country were road got flooded. We were just touched by the edges of some thunderstorms and did hear some thunder in the distance. I saw some lightning. Still, I guess, it was just a few mm of rain. This breaks a periode of 38 days with no measurable amount of rain.

At 17:24, I bought the book Documenta 8 written by Monika Goedl and Christian Bromig in German and published by Weber & Weidemeyer in 1987, ISBN:9783925272134, from charity shop Het Goed for € 6.00. It is the catalogue of the documenta 8 exhibition.

100 Arists' Manifestos

This evening, I finished reading the book 100 Artists' Manifestos: From the Futurists to the Stuckists edited by Alex Danchev, which I started readon November 4, two days I bought the book on November 2. I found the book interesting to read, although most of the manifests are hard to read and/or grasp. I did like all the introductions and the short biographs about the writers.

AKI MUPI route 2023

I found AKI MUPI ROUTE 2023 yesterday evening. This shows where to find posters from the AKI graduates on the back of the MUPI advertisement signs. MUPI is an abbreviation for the French 'Mobile urban pour publicity et information'. In the past two months, I have been working on drawing all possible biking routes between the MUPIs I knew about with Google Earth. This years route contains some MUPIs that I had not included yet, so I spend some time adding these. (See the file MUPIs.kmz, which is likely to be updated in the future.) I also adapted the program I wrote last year to deal with the new format, because I have been using multiple lines to connect the various MUPIs together. I have globally grouped the lines with the MUPI they are close to. I also had to adapt the program, because the distance matrix has become asymmetric due to the fact that I have drawn different routes depending on the direction. I also implemented step 1 and 2 of the Hungarian algorithm. I also made some small changes, possibly fixes, to the TSP solver although I did not use it. With the latest version of the ParseMUPIkml2.cpp with a bucket size of 10,000 solutions for each pass, I found a route with a distance of 18177 meter that I think I am going to follow. (The route on Google Maps).

Dune part two, second trailer

There is a second trailer for the upcoming Dune movie: Dune: Part Two | Official Trailer 2. I started writing down all the shots in this trailer, but I felt that there were too many for a post. Below a list of things that are said in this second trailer: Only a few of these text can be found in the book. Some are not found in the book, but can some way be based on it. I think that it is kind of difficult to bring Paul's struggle with his vision to the screen and that Villeneuve has chosen to translate it into interactions between the main characters.

Some more reaction videos I watched in the past weeks:

AKI Finals

I went to the AKI finals 2021/2022 exhibitions at the AKI building. I found the works of the following graduated students noteworthy (in the order I encountered them):

A part of the exhibition is at Rijksmuseum Twenthe, which I have not visited yet. At 18:50, I bought the book AKI Academy of Art & Design 2023 edited by Ina Bode, written in Dutch and English, and published by AKI Academy of Art & Design on Thursday, June 30, 2022, ISBN:9789075522433, for € 15.00.
