I’ve always been a fan of extremely small Linux installs. Back when I first started using computers, I didn’t have access to great hardware. In the early 2000s I was using Pentium133 and eventually a Pentium III based system and I remember running floppy Linux (live boot off a floppy disk) and DSL (damn small Linux) in attempts to maximize the performance of the hardware I had.
Running Linux on a tiny ESP32 board just blows my mind!
Hey! My first venture into the Unix-like world was on a Pentium 133 gifted to me by my 2nd cousin. He introduced me to the open source world via OpenBSD. OpenBSD will always hold a special place in my heart but I absolutely eat up anything and everything open source.
