🇩🇪 — Hi, ich bin Martin Ueding; Physiker, Maschinenlerner, Softwareentwickler und engagiere mich für die Mobilitätswende. Ich habe recht früh mit dem Programmieren angefangen und schreibe darüber im Bereich »Code & Zahlen«. Im Physikstudium bin ich immer weiter in die Computerphysik gegangen, meine Studiumsunterlagen sind noch immer Teil dieser Webseite. Nach der Promotion bin ich in die Wirtschaft gewechselt. Seit dem Abitur habe ich meine Wege mit dem Fahrrad erledigt, Radtouren unternommen und irgendwann auch Radreisen. Inzwischen bin ich auch Aktiver im Radentscheid Bonn.

Aktuell schreibe ich am meisten zu Verkehrsthemen, manchmal auch noch über Wissenschaft, Maschinenlernen oder anderen Dingen, die mir einfallen. Die eher technischen Dinge schreibe ich meist auf Englisch, den Rest auf Deutsch.

Man kann mich per E-Mail, Threema oder Telegram kontaktieren, oder mich auf Mastodon, Pixelfed und GitHub finden.

Logistics of Computer and Board Games

There is a vast array of computer games available. There are single player games without a campaign (Tetris, Mine Sweeper) that you can just play without preparation. Then there are games with a story (The Witcher, Mass Effect, Bioshock). These solitary games are not the scope of the articles. Rather I am concerned with multiplayer games. And there are the kind of cooperative games (Saint's Row, Borderlands, Diablo) and the competitive games (MechWarrior Online, World of Warships).

How should I buy my books?

These days one can get a lot of books electronically. I am still not sure whether I prefer books in paper or electronic form. It seems that in principle I prefer electronic books, but the way that one can actually buy them is against my preferences. This is is the crucial distinction that will lead to a conclusion.

Attaching a Display

Personally and professionally I have seen my fair share of display connectors. At this point it has a Kafkaesque complexity. At the theory department we have computers ranging from around 2006 to current ones. This means that we also have all kinds of display connectors on the workstations and tablets:

China Trip Wrap-Up

My return flight to Düsseldorf was scheduled for Saturday at 01:50+0800. Arrival at Düsseldorf would be something like 06:30+0200, so I would get home in the morning and with sleep on the plane the jet lag should not be that bad. At the airport I bought such an U-shaped pillow. A lot of stores outside of the security area carry them. They ranged between around 300 CNY to a cheap feeling one for 120 CNY. I ended up with a mid-range one, it is amazing how many different models there are!

Food in China

Being a vegetarian with some food allergies makes traveling a bit more involved. I have heard that Chinese cuisine uses a lot of peanuts, therefore I wondered how people cope with that.

Summer School in Běijīng (北京市), China

Běijīng (北京) literally means northern (北) capital (京). The name "Peking" is the official name in English and German and corresponds to the same city. I just prefer to use the Chinese name. There is also the city of Nánjīng (南京), the southern capital. Depending on how you count there are 23 million people living in Běijīng, which is completely beyond my comprehension. Compared to Wǔhàn that is just a factor 2 adding to the factor 50 Wǔhàn has to Bonn.

Emoji Keyboards

These days I include a lot of emojis in my chat messages. Back in the day one would write stuff like :-D or include some little pixel graphic, but now we just have unicode symbols for this: 😃. Since these symbols are not on a regular keyboard (except perhaps for laptops with touchscreen bars above the keyboard), one needs to enter them somehow different. And this is where it starts to become really inconsistent.
