Performance on MS Teams was very bad on M1 MacBooks compared to other applications. But Microsoft is working on a native osx-arm64 version which I installed. And I have to say that I am blown away from the speed improvement. It’s like day and night. If you’re interesting in trying out non released Teams versions […]

The default configuration of Spring Boot tells quite a lot about errors and software versions used. This is a potential security leak and therefor should be avoided. One step is to get rid of server information from header and default error pages. Result With my suggested changes in place the default error result pages will

This error can occur when you try to run an amd64 image on the wrong architecture. For example I tried to use the image ‘catatnight/postfix‘ and it didn’t start on my M1 Max. The working fix was to switch from image entry in my docker-compose.yml to a build entry and rebuild the image based on

With a release date in 2018 I expected to have my Xiaomi Mi Mix 3 at least for a few years – if I manage not to crush it like its predecessor. Already in 2020 I had to learn that Xiaomi stopped support for the former flagship device. Really very disappointing and not a big

I installed Krita 5.0.2 on my Windows 10 machine to test it with my old Wacom Intuos 5. The first attempt lasted only a few minutes because Krita was flickering again and again which made working with it impossible. First I thought maybe my old tablet has an issue but after unplugging it and even
