Tech, life and everything else
Last year I wrote a tutorial about how it’s possible to run Linux GUI apps on Windows using the Windows Subsystem for Linux. WSL 2 (with an integrated Linux Kernel) is coming soon, but Microsoft announced they are bringing support for Linux GUI apps to Windows 10 too. While I still prefer to use Linux directly, I think it’s still a great announcement and new feature. It’s definitely the year of Linux on the desktop.
The German government tasked SAP and Deutsche Telekom with the development of an open-source contact tracing app (named “Corona-Warn-App”) using the APIs from Google and Apple. Now they’ve published the code for the backend server. I took a quick look at the code and I’m quite a bit surprised about the quality and best practices used. They are using the Java-based Spring framework and use Postgres and minio to store data. Everything running in Docker. Even the Docker images are build using multi-stage Dockerfiles.
Yesterday I wrote about a new “blog feature” showing below a post places on this blog where the post was mentioned. Unfortunately this has a high complexity and is not very fast. Today I tried (and managed) to improve the algorithm so that the complexity is just O(n). However, the code does not work as I expected it to, because Hugo does not provide a way to use global variables.
I wonder when the point comes where it is too much effort for me to find workarounds and I just build my own page generator according to my own needs… Most of my blog setup I have already developed myself.
To give readers a bit more context, I’ve extended my Hugo theme so that it will be displayed below each post if it is mentioned or linked in another post on my blog. This increases the build time from about 7 to about 17 seconds (on my machine it takes 2 seconds, but it is also much faster than the VPS), but I don’t know how I can make it more performant. After all, for each article it is necessary to iterate through all the other articles and see if the content contains a relative link to the post.
Update: I disabled this again, because I don’t like this much increased build time.
It is interesting to see that I am not the only one who has a problem with email logins. I find email logins make everything much more complicated than simple password-based authentication. I use a password manager both on the computer in the browser and on my smartphone and can easily have complex passwords filled in automatically.
I shared a link to 98.css the other day. Now there is also XP.css in the style of Windows XP. This brings back some memories, because I actually worked quite a lot with Windows XP. But I am curious about 7.css and 10.css. 😂
During the apprenticeship our instructor always wanted us to practice 10-finger typing together. A good idea, because I believe that if you really master this skill, you can put the words (or the code) you think about on the screen with an incredible speed. We used to do this with the program “TIPP10”, which is available both as an offline and an online version.
Many may not know it, but I am the founder of AndroidPub, a Medium publication about Android development. (The site is still running on a subdomain of my first domain, although I registered it’s own domain a long time ago.)
I almost never play computer games, but what I sometimes like are classic logic games like Minesweeper or Sudoku. And I must say, the versions from GNOME (on Linux), GNOME Mines and GNOME Sudoku are really nice. Simple design, plain and focused on the game with the most important features. I have also just discovered on the GNOME Wiki that there are a number of other simple games available, like 2048, Four in a row or Chess (Chess is probably not so simple). I install most apps via Flatpak and Flathub, but most distributions should also have them directly in their repositories. The advantages of Flatpak are that it is very easy to install and you always get the latest version.
