Re: Telcos Dude, you've got to be trolling. I'm not even going to waste any time figuring out who really discovered all of those things. Off the top of my head I know that AT&T was involved in the early development of UNIX, along with MIT and I don't know who else. AT&T quickly dropped that waste of time, and the developers went elsewhere to continue their work. As far as the UNIX we use today, UC Berkeley gave it to us, although a judge recently decided that Novell owns it when SCO tried to claim that they did. I guess even if you give something away to everyone, a court can decide that someone owns it.
None of that really matters, cause the Wizard of OS, Theo de Raadt, continues to give us the very best version of a UNIX-like OS available today. All hail Theo, or die the slow death of unaudited code.
Re: Telcos Since you like the Wikipedia, from the UNIX article:
In the 1960s, the Massachusetts Institute of Technology, AT&T Bell Labs, and General Electric worked on an experimental operating system called Multics (Multiplexed Information and Computing Service), which was designed to run on the GE-645 mainframe computer. The aim was the creation of a commercial product, although this was never a great success. Multics was an interactive operating system with many novel capabilities, including enhanced security. The project did develop production releases, but initially these releases performed poorly.
AT&T BELL LABS PULLED OUT AND DEPLOYED ITS RESOURCES ELSEWHERE. One of the developers on the Bell Labs team, Ken Thompson, continued to develop for the GE-645 mainframe, and wrote a game for that computer called Space Travel. However, he found that the game was too slow on the GE machine and was expensive, costing $75 per execution in scarce computing time.
Thompson thus re-wrote the game in assembly language for Digital Equipment Corporation's PDP-7 with help from Dennis Ritchie. This experience, combined with his work on the Multics project, led Thompson to start a new operating system for the PDP-7. Thompson and Ritchie led a team of developers, including Rudd Canaday, at Bell Labs developing a file system as well as the new multi-tasking operating system itself. They included a command line interpreter and some small utility programs.
In the 1970s the project was named Unics, and eventually could support two simultaneous users. Brian Kernighan invented this name as a contrast to Multics; the spelling was later changed to Unix.
UP UNTIL THIS POINT THERE HAD BEEN NO FINANCIAL SUPPORT FROM BELL LABS. When the Computer Science Research Group wanted to use Unix on a much larger machine than the PDP-7, Thompson and Ritchie managed to trade the promise of adding text processing capabilities to Unix for a PDP-11/20 machine. This led to some financial support from Bell. For the first time in 1970, the Unix operating system was officially named and ran on the PDP-11/20."
Sorry, the shouting is mine, it's not meant as shouting. I don't know how to underline or any of that other cool stuff. I don't know him, but I doubt if Ken Thompson would agree with you that Bell Labs "gave" us UNIX, considering they didn't even bother paying their own employee to develop it, until they thought they could make some dinero from his efforts. Besides, don't always believe everything you read in the Wikipedia.
