Happy 25th Birthday Linux

25 Years and still going strong! There’s been up and down’s along the way but Happy Birthday to Linus’ creation.


It was 1991 when Linus Torvalds started work on what was to become the now famous linux kernal.

At the age of 21 he built something that would go on to power the majority of servers across the globe.

Here is his original usenet post:

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 πŸ™‚

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