Configuring download directory for Chromium and Firefox snaps
So I read this and this and solved my problem. Basically I bind /temp/download to /media/$USER/download and then I can set the download directory in Chromium and Firefox snaps to /media/$USER/download and my downloads go where I want them. This was actually harder to figure out than it should have been.
Technical Writing @ Google Developers
Today I came across some tech writing courses available from Google: Overview of technical writing courses.
VirtualBox display settings
Note to self: I had a problem with the GUI on my Kubuntu VM not working under VirtualBox on a Kubutnu host. I fixed the problem by changing the Graphics Controller on the VM from VBoxSVGA to VMSVGA. I have no idea what the difference is, except that the latter works and the former doesn’t!
Searching for ATTINY85 over on AliExpress and sorting by popularity renders some interesting results.
Raspberry Pi Pico
The Raspberry Pi Pico looks interesting. Gonna get myself some for playing with.
I’m gonna try one of these Arduino Nano knockoffs: Upgraded /NANO V3.0 ATmega328 Extended Compatible for arduino ATTINY88 Micro Development Board 16Mhz /Digispark ATTINY85. They seem to be an ATtiny88 in an Arduino Nano form factor.
Zebra Classic Case for Arduino Nano

Arduino OLED display
So I followed these instructions to get my OLED display working on an Arduino Nano. I have a 0.96″ 128×64 I2C OLED display:
4 Digit 7 Seven Segment display
I’m planning to get a bunch of these: 0.56 Inch 7 Seven Segment 4 Digits Red Clock LED Display Common cathode Time 12 Pins. Then I need to figure out how to drive them from an Arduino Nano…
