Exhibitions

I went to see some exhibitions in the city. First, I went to photo gallery Objektief to see the exhibition Voor Orhan / Voor Fernando. Quite intereseting, not only the photographs, but also the subject and the materials used. Next, I went to Concordia, where I saw Monument Levenslicht by Daan Roosegaarde, which is part of a larger project.

Universal palindrome date

Today is a palindrome date when written like 02/02/2020 (MM/DD/YYYY) or 2020.02.02 (YYYY.MM.DD). The previous such date was November 2, 2011, which is 3014 days ago. It is also palindrome data when written in like 02-02-2020 (DD-MM-YYYY). The previous such date was February 21, 2012, which is 2903 days ago. This makes is a universal palindrome date of which there are only twelve. The previous such date was November 11, 1111, and the next will be December 12, 2121. Note that this is also a "digital" rotation date, which means that if the date is written on a seven-segment display it looks the same when rotated over 180° This is a subset of the palindrome date that are made up out of the digits 0, 2, 5, 6, 8, and 9. It is the first for the formats MM/DD/YYYY and YYYY.MM.DD and the second for the DD-MM-YYYY format. This is the second special date of this year.

Rotterdam

I went to Rotterdam, where there is Art Rotterdam Week. At the Rotterdam Tourist Information located in the central station, I got the free Art Rotterdam Week map. I went to the exhibition TECART - Quantum Supremacy, which is organized by PLANETART, which also organizes GOGBOT. The exhibition is smalller than GOGBOT. I liked the following exhibits: I went to Doppio Expresso and had some 'White Czar' tea: "Pai Mu Tan" white tea, bergomot, mandarin, vanilla, rose petals. On the way back, I took a picture of the new depot of Museum Boijmans Van Beuningen. At the entrance of the road to TECART, I had a second look at a replica of the DeLorean time machine from Back to the Future. I walked through the city. At 15:17, I bought the book Energieen edited by Wim Beeren, Frits Keers, and Din Pieters, written in English and published by Stedelijk Museum in 1990, ISBN:905006034X, from De Slegte Rotterdam for € 20.00. I also went to bookshop Donner. I took the train home and made a stop in Utrecht, where I visited the bookshops Steven Sterk and Broese Boekverkopers. At 19:19:36, I bought the book How to f*ck a woman: leer van een vrouw wat vrouwen willen written by Ali Adler, translated from the English How to F*ck a Woman, an Insider's Guide to Love and Relationships into Dutch by Margot Reesink, published by Gottmer Uitgevers Groep in 2016, ISBN:9789401302753, for € 7.90 from the latter one.

C# generics and class extensions

I have been programming in C# for some time now, and I am beginning to appreciate the language more and more. I often use a Dictionary class for collecting information about certain items. When you found an item, you want to know if you already collected some information with the item, and if not you want to add an empty record with said item, to store the information. The Dictionary class does not have a method for doing this. Using generics, I wrote a derived class with the method. But than someone suggested, that you could also implement it as a class extension. It took me some time to figure out how to specify the constraint that the class for the 'value' of the Dictionary class has a default constructor: after the header of the method with where V : new(). The final result became:
public static class DictionaryExtensions
{
    public static V GetOrAdd<K, V>(this Dictionary<K, V> dict, K key) where V : new()
    {
        if (dict.TryGetValue(key, out V value))
            return value;
        V newValue = new V();
        dict.Add(key, newValue);
        return newValue;
    }
}

Palindrome date

Today is a palindrome date when the date is written in the format MM/DD/YY: 02/11/20. This is the third special date of this year.

A Closed and Common Orbit

This evening, I finished reading the novel A Closed and Common Orbit by Becky Chambers, which I started reading on January 30, the day I bought it. The novel is placed in the same universe as The Long Way to a Small, Angry Planet but it not a real continuation of the story, because the main characters in the first novel do not return in this novel. I understand that the third novel is again about different persons. I guess that there would have been room to let some of the characters of the first novel return in this second novel. This novel, much different from the first novel, reads more than one (actually two) story than like a collection of more independent stories. The first half is a little slow.

At 17:59, I bought the book Spirits of Internationalism 6 European Collections 1956-1986 written by Anders Kreuger, Joram Kraaijeveld, and Steven Ten Thije, written in Dutch and published by Van Abbemuseum Eindhoven in 2012, ISBN:9789490757069, from charity shop Het Goed for € 1.50.

Picasso & Matisse

Conny and I went to the Rijksmuseum Twenthe to see the exhibition Picasso & Matisse. Beauty is a line. I found the following works worth mentioning: Next we walked through the exhibition Berlin Geisterbahn with photographs by Fons Brasser. I took some pictures on the maps of the S-Bahne which were on display. Next we saw the exhibition with works by Ben Akkerman. I liked the works: From this we walked through the exhibition with works from the collection and went to see the exhibition Onzalige bossen - Onzalige tijden with drawings by Geert Voskamp. I liked the works: Finally, we saw the exhibition Ars longa, vita brevis. Although, I walked through this exhibition many times, walking through it with Conny made me see works that I had missed the times before, because she made me pay attention to them. So, it is always worth to go see some again with some one else. We completed our stay at the museum with some sausage roll with some tea.

17.4°Celsius

The record temperature of 17.4°Celsius at Twenthe Airport (beating last years record of 14.1°Celsius) was reached at the start of the evening. These high temperatures where caused by Storm Dennis, which pulled warm air from the South. Around seven, a strong cold front passed with a lot of rain, causing the temperatures to drop about eight degrees within ten minutes.

25 years

Today it is 25 years ago, that I wrote my first entry in this online diary. I was not one of the first to start an online diary, but I wonder how many of them are still writing them. One of them, Carolyn L Burke, already stopped many years ago.

BodyBuilding

I went to TETEM art space for the opening of the exhibition BodyBuilding (info in Dutch) developed by the Hackers & Designers collective with the following people: It is an interesting exhibition. Finding the right balance between an exhibition being self-explainatory and dealing with complex matters that can not be grasped immediately. At 17:12, I bought the book On & Off the Grid edited by Genevieve Costello, written in English and published by Hacker & Designers in 2017 from then for € 15.00. The back of the cover has the text: "Printed with conductive ink the cover of this book functions as a controller for layouting."

2001: A Space Odyssey

This moring, I finished reading the novel 2001: A Space Odyssey by Arthur C. Clarke, which I started reading on January 30 after I bought it on Tuesday, August 22, 2019. I watched the movie adaptation on May 27, 1978. Especially the first part of the book feels even slower than the movie. There are many differences between the plot of the book and the movie. Those have been detailed elsewhere. But even without these, the book has a different taste, much more focussing on the scientific aspects and also explaining the last part in far more detail.

Snow!

This morning, I heard about snow on the news. When I opened the blinds, I did some (wet) snow falling from the sky. There was some snow on cars, plants, the grass, and such.

Virus

I am a little worried about the procedure that the Dutch goverment (according to the advice of Netherlands National Institute for Public Health and the Environment) is taking to limit the spread of COVID-19. They are stating that transmission only occurs when people get ill. This, while there is scientific evidence, such as in the article: Transmission of 2019-nCoV Infection from an Asymptomatic Contact in Germany, that people can infect others before they have any signs and also that many people do not get ill to an extend that they need hospitalization. Maybe they do this to not spread panic and cause many people, who just have an ordinary cold, to request for a test. The reported cases in the Netherlands are related to the outbreak in Italy. It is difficult to know what is the best strategy to deal with this outbreak.

Leap day

Conny and I went to the Schrikkelfestival in and around Roombeek. We visited the ten locations in the order they were given on the map. At the CeeSpot Containers we saw the works by Etta Maduro. She was present and gave some explaination about her works. At XPO we saw the drawing by Judith Schepers. (I saw here works before on April 29, last year and met her before on June 9.) At Dynamo Expo we saw watercolours by Veronica Berkvens. At the Arendsmanhuis we met with Danielle Spoelman, who I met before last year June with her project together with Judith Schepers. I showed her the stamp I in my diary. We also went to the Rijksmuseum Twenthe where we were allowed to visit all exhibitions. It was quite busy and we only looked at an exhibition about drawings. At 'Van de Jeugd Archtects' the 'Co, trio 054' was playing. I got on of the free Schrikkelbeeld cubes by Wout Zweers. There were also two works by Rinus Roelofs. The last location was the Tankstation. I liked some of the works by Nour-Eddine Jarram and a painting by Ray Andreas. We went to the reopening of Sickhouse at the new location. At bookshop Broekhuis were at the top floor we saw the impressive exhibition of drawings by Jacq de Groot.
