I was asked to fix this error that appeared porting a Qt 5 app using qzxing to Qt 6 on Windows: The reason for this error comes from the fact[...]
Many devices nowadays come with a notch at the top of the screen. You can clearly avoid drawing where cutouts are placed and ask the system to create a window[...]
Sometimes I need to have specific versions of Qt to build apps and run CI tasks. In this article I introduced what I used for this purpose: a multi-arch docker[...]
I wrote an article about this topic in the past here. However, I had the chance to work more on the topic so this is a follow-up to that article:[...]
When developing products and managing servers I frequently notice that properly formatting and colorizing text, logs and generic output in the terminal is very useful. Errors, warnings and messages are[...]
Raspberry OS based on Debian bullseye was recently published. The compiler provided with this new version was updated to 10.2.1. As usual, I need to cross build many large projects[...]
