I switched everything over to rootless podman a year or two back. Some containers ended up with permissions issues when trying to read their old data - caused by being run with a different UID. This was really the only problem I ran into, but I would have had the same issue switching from rootful docker to rootless docker.
We wrote up a fun little project where you make a light-up caterpillar using conductive dough, a 9V battery, and LEDs. It’s simple enough for kids to build (and safe with supervision), but still highlights core electronics concepts like polarity, circuits, and conductivity.
The post includes step-by-step instructions, photos, and some notes on why the dough works as a conductor. We think it's a fun way to introduce kids to electronics or just to play around with a squishy medium for prototyping.
Absolutely zero regrets, would never go back.
