Recently I ran into an interesting graphics issue while developing a Rust GTK4 application under WSL2 on Windows. The application itself worked fine on native Linux systems, but under WSLg it produced a stream of Mesa and EGL warnings during startup.

While working on the Loewe TV remote I discoverd a blog post where someone was investigating a problem with a Ziggo remote control. The remote was draining the button cell batteries in a few days.

I found two Loewe TV remote controls at the local thrift shop. They felt hefty and oozed the kind of quality you expect from Loewe. At 50 cents each, I decided to take them home. You never know how something like this might become useful in a future project.

Simple python script to check the state of MySQL replication and send an e-mail in case of problems.

Driving WS2812 and WS2812B LEDs from an STM32 does not require carefully timed bit-banging. SPI can generate the waveform for you, as long as each LED bit is expanded into a short SPI bit pattern. This post explains the timing math and the full reasoning, but builds toward the practical result: use an 8-bit encoding, send the data in GRB order, and run SPI somewhere around 3 to 6 Mb/s.
