This brings back good memories.

When I was in college I didn't have my own computer so I relied on the Windows machines from the library.

That's when I discovered Slax and Puppy Linux [1] and all its different variants. Such a beautiful thing to boot into these pendrive distros and discover the world of Linux through them without altering the host system.

Good times.
