Linus Torvalds' E-Mail Announcing the Creation of his OS

From: torvalds@klaava.Helsinki.FI (Linus Benedict Torvalds)
Newsgroups: comp.os.minix
Subject: What would you like to see most in minix?
Summary: small poll for my new operating system
Message-ID: <1991aug25.205708.9541@klaava.helsinki.fi>
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, andI'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 :-(.

The history of the 'mouse'

I have always been fascinated by the history of 'mouse'. It is undeniable that computering, as we know it, it is a consequence of the invention of the 'mouse'.

But also, it is interesting, that the case of the mouse exemplifies perfectly how one amazing invention can pass totally unnoticed until someone sees its potential.






Referring to the 'mouse', it was invented by Xerox in 1971, but it was Apple who saw its commercial potential:

"In 1970, Xerox opened the Xerox PARC (Xerox Palo Alto Research Center) research facility. The facility developed upon many modern computing methods such as the mouse and graphical user interface to create the paperless office. From these inventions, Xerox PARC created the Xerox Alto in 1973, a small minicomputer similar to a workstation and personal computer. The Alto was never commercially sold, as Xerox itself could not see the sales potential of it. In 1979, several Apple Computer employees visited Xerox PARC, interested in seeing their developments, including Steve Jobs. Jobs, and the other Apple employees, saw the commercial potential of the GUI and mouse, and began development of the Apple Lisa, which was eventually introduced in 1983 for US$10,000, it was a commercial failure."
