26 years ago Linus Torvalds sent out this message to the comp.os.minx newsgroup.

Hello everybody out there using minix -

I’m doing a (free) operating system (just a hobby, won’t be big and
professional like gnu) for 386(486) AT clones. This has been brewing
since april, and is starting to get ready. I’d like any feedback on
things people like/dislike in minix, as my OS resembles it somewhat
(same physical layout of the file-system (due to practical reasons)
among other things).

I’ve currently ported bash(1.08) and gcc(1.40), and things seem to work. 
This implies that I’ll get something practical within a few months, and
I’d like to know what features most people would want. Any suggestions
are welcome, but I won’t promise I’ll implement them :-)

- Linus

PS. Yes — it’s free of any minix code, and it has a multi-threaded fs. 
It is NOT protable (uses 386 task switching etc), and it probably never
will support anything other than AT-harddisks, as that’s all I have :-(.

Fast forward to today and Linux has more than 12 000 contributors from over 1300 companies that contribute to the Linux kernel.

The Linux Foundation released a fairly detailed progress report, including an infographic which I was tempted to include here but you can view it in it’s original context here.

While you’re over there, remember you can be a sponsor of the Linux Foundation too.

Happy Birthday Linux and a giant thanks to not only Linus but every single one of the contributors that have taken part of it over the years.
