"Things to Try When You Can't Make a Trait Object"

Trait objects are Rust’s usual mechanism for dynamic dispatch.

This post describes several options for handling an inability to create a trait object, discusses their trade-offs, and describes why the trait object limitations exist in the first place, and what those limitations are exactly.

The EU border police Frontex is under fire for its involvement in human rights violations at the EU’s borders. Now, they want to silence those exposing their wrongdoing.

Frontex is taking us to court.

Today, I went crazy and built a command-line tool and shell script library for creating interpolated number sequences. This allows to create css-ish animations with easing functions in the terminal with plain POSIX-compatible shell scripts.

Unfortunately, terminalizer is not working under Fedora, which forced me to screen capture the terminal output with Peek. Not as fancy as usually :D

The tool is named shease 🧀 as in shell easing functions.

Der verstärkte Einsatz von Freier Software ist ein zentraler Baustein für mehr Digitale Souveränität.

Gemeinsam mit einem starken Bündnis aus Verwaltung, Politik, Wirtschaft und Zivilgesellschaft fordern wir die Schaffung eines Code Repository mit Freier Software für die öffentliche Hand.

I've now heard plenty of times that #Wayland compositors are less power efficient than #Xorg because they do compositing, which is blatantly wrong. My Wayland setup uses less energy than my Xorg setup did WITHOUT compositing. This is not that surprising when you take a look at how the whole thing works. (I have no comparable values for window managers that have built in compositing but I imagine Wayland compositors to still perform better here)

Using Discord for your Open Source project. I hate it.
