Now that Steve Jobs has come up with NeXT, I thought I should look up Mach. Can someone mail me some info about papers , books detailing mach.

Under a heading `Controversy' in issue 2 of the Usenix Computing Systems journal, there is an interesting article about availability of OS source, with respect to Unix & other systems. Could Mach (or a sanitized AT&T cleansed version!) be a candidate for replacing Unix in the academic world? I've read that once CMU have removed all the AT&T source, they intend to distribute it for a neglegible fee, so that people like the Free Software Foundation can use it for Gnu, among other things. Mach seems to have some of the features mentioned in the article. e.g. lightweight processes, simple IPC & the simplicity and elegance of the early Unix systems. Just wondering. Sorry if this this already been discussed - stuff takes longer to get to these shores :-( -- Ed Wilkinson @ Computer Centre, Massey University, Palmerston North, NZ uucp: {uunet,watmath!cantuar}!vuwcomp!csvaxa!edward DTE: 530163000005 Janet/Greybook: E.Wilkinson@nz.ac.massey Phone: +64 63 69099 x8587 CSnet/ACSnet/Internet: E.Wilkinson@massey.ac.nz New Zealand = GMT+12

In the United States, at least, this is a much more powerful form of protection than just copyright. If I read ATT source, then sit down and release my free rewrite then I will expect that the nice ATT lawyers will ask me to explain, in court, how I did not use the "techniques and methods" which I agreed to hold secret when I signed their piece of paper. This is apparently (one of) the reasons that Stallman refuses to look at ANY code that is covered by a Unix source license. Disclaimer: I am not a lawyer, and do not presume to speak for RMS, CMU, ATT, or any other acronym. -- Please send comp.sources.unix-related mail to rsalz@uunet.uu.net.

Not only that, but Mach is *not* free of AT&T code, even in the kernel. -- Ed Gould mt Xinu, 2560 Ninth St., Berkeley, CA 94710 USA {ucbvax,uunet}!mtxinu!ed +1 415 644 0146 "I'll fight them as a woman, not a lady.
