New blog post: In case you've ever wondered why Game Boy Advance boards have a 10 nF capacitor on the d-pad up input, but not on the other directions (left, right, down): gekkio.fi/blog/2026/ga...

Sometimes you just have one of those days when you ponder the biggest questions in life and want to ask "how does To provide five frequently modified core application logic filenames, I would need: work?"

On the way to Oxidize conference in Berlin. If you want to chat about Rust, Game Boys, or any other interesting topic, look for a bald (and bold) Finnish guy 😃

One of the most annoying UX behaviours is showing an "empty" result when there's a technical error, and not indicating the error at all. Spotify search? "lol no results found for X" Mobile app of my *bank*? "lol you have no accounts" Accounting software? "lol you have no invoices/receipts/anything"

Maybe I'm weird but the fact that LibrePCB is strategically moving towards Rust is quickly making it more attractive to me. I've been a happy KiCad user for almost 10 years but I've seen my share of crashes, bugs and various "C++ problems".

My opinion about USB-C was forever changed when I recently watched in horror as somebody shoved a USB-C cable into a USB-A port, shorting the pins with the USB-C plug shell. The idea of having a computer with no USB-A ports and *only* USB-C doesn't seem so silly anymore... 😅

Age yourself with the first computer you used.

Finished testing this *35-year old* CR1616 battery on this Game Boy cartridge. CR1616s typically have a 60 mAh nominal capacity (with a 30kΩ load). In my test I got 31 mAh out of this battery with a 10kΩ load until 2.0V cutoff so the battery had *at least 50%* capacity left after 35 years. Wow!

Thanks TI website for this lovely validation error 😅 I guess what they really mean is "domain name", not URL (or URL without protocol? 🤔), but in any case "Please enter the URL in English" is one of the worst validation error messages I've ever seen

Mwahaha, somebody at Github pushed to production and messed up the home page a bit 😅 my feed is now sorted oldest to newest for some reason

Why is it always the big corporations with all the money in the world that have the worst websites that are down exactly when you need them? Würth and Samtec, I'm disappointed! 😬
