+Subject: What would you like to see most in minix?
+Summary: small poll for my new operating system
+Date: 25 Aug 91 20:57:08 GMT
+Organization: University of Helsinki
+
+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 (torvalds@kruuna.helsinki.fi)
+
+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 :-(.

+::: {.incremental}
+- **2002**: Kernel team adopts **BitKeeper**, a proprietary DVCS, free to use for open source projects
+- **April 2005**: Free license revoked after a licensing dispute
+- **April 2005**: Torvalds writes **Git** from scratch in ~two weeks
+- **July 2005**: Torvalds hands maintenance to **Junio Hamano**, who still leads Git development today
+- **2008 onward**: **GitHub** launches, making distributed workflows (fork/branch/PR) mainstream far beyond kernel hacking
