Replacing Liquid Metal on an Asus Zephyrus G15's CPU
I’ve been using the Asus ROG Zephyrus G15 as my daily driver for a few years now.

Programming a CH32v003 with light
A comedic example, parked nicely on the thinnest wedge of the venn diagram, is the HamFurs – people who do amateur radio while wearing fur suits. While it isn't my cup of tea, I love that such a group exists. They seemed like nice people when I chatted to them.
