Tiny Core Linux: a 23 MB Linux distro with graphical desktop

I've used many of these small Linux distros. I used to have Tiny Core in a VM for different things.

I also like SliTaz: http://slitaz.org/en, and Slax too: https://www.slax.org/

Oh and puppy Linux, which I could never get into but was good for live CDs: https://puppylinux-woof-ce.github.io/

And there's also Alpine too.

wondering what's your typical usage for those small distros?

In college I used a Slax (version 6 IIRC) SD card for schoolwork. I did my work across various junk laptops, a gaming PC, and lab computers, so it gave me consistency across all of those.

Booting a dedicated, tiny OS with no distractions helped me focus. Plus since the home directory was a FAT32 partition, I could access all my files on any machine without having to boot. A feature I used a lot when printing assignments at the library.
