I'm very fond of Puppy Linux, it's how I learned a lot of Linux skills as a preteen!
I had Puppy Linux on a USB stick when I was a kid. It was the first Linux flavor I used for an extended period of time for two very specific reasons. It was small, I didn't have much time to spend at the library waiting for downloads, and I couldn't afford a very large USB stick.
I had nuked the MBR on our family computer. I never figured out how I'd done it but that the fix was to restore it using a Windows recovery disk. But that took about 2 years of using Linux live CDs as a compute environment, eventually progressing my computer knowledge to trying to install Ubuntu to the hard drive so I could start saving files, and saw that the Windows partition existed on disk and did a bit more research with that knowledge to learn about MBRs and dual booting. The Tech Tv channel back in the 2000s was a great way for a 10 year old to learn about computers!
Thanks for the trip down memory lane, and for kicking off the acquisition of skills I've centered my career around!
I wasn't sure Puppy was still actively developed.
It looks like after 3 years there is a (early?) release available: 2510-25111 trixiepup. 11/19/25
https://distrowatch.com/table.php?distribution=puppy
But back in June there was some event that used the language Dev Leaves and Turn Off The Lights
TrixiePup64 11.1.1 (Development discontinued) 6/7/25 https://forum.puppylinux.com/viewtopic.php?t=14554
Maybe positive things happened between June and Nov.
There are several active community derivatives. My favorite is QuickPup64, the dev releases new versions every 1-2 months, and is very responsive to feedback and issues.
