I played the game with them, when they were very young. They loved every minute of it - with their uncle performing impromptu dramatization-translations :-) I am seriously considering playing it again with them this summer :-D

A USB tester - it just reports the voltage (5V) and the current. As you can see in the video, the current hovers around 10mA, spiking to 20mA when we use the speaker.

If you are OK with external USB drives, I did just that with my Atomic PI [1] (Atom-based, 35$ SBC, 3.5W idle, running Debian on its internal EMMC, with two external USB drivers in ZFS-mirror configuration). [1] https://www.thana

Thank you! I had noticed the same problem, but was not aware of this excellent solution. I just applied it, and it works perfectly... and I removed the dozens of Haskell libraries that were there just for Pandoc. For anyone else interested,

Interesting interview - thanks John! Didn't know there was a UFS2 "phase" before ZFS... I wonder how much time those fscks took! :-)

After so many months, I had no idea what tools I was running in that command line... And therefore, the effect of any signal seemed far more dangerous to me, than extracting the actual command from my shell's memory.
