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

Screenshot of Github Home page with multiple feed entries. The top entry says "3 weeks ago" and the bottom entry says "2 weeks ago"

Screenshot of Github Home page with two feed entries, scrolled down until the More button appears. The upper entry says "20 hours" and the lower entry says "21 minutes ago"
