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 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 filesystem (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 :-(. 5. ...him?

Thecarthathadanicecreamallergy General Motors got a customer complaint his new GM Pontiac was allergic to ice-cream. ...I won't blame you for not answering me, because I know it kind of sounds crazy but I have a car that is allergic to ice-cream. I recently purchased a new Pontiac and since then my trips to the store have created a problem. Every time I buy vanilla ice cream, when I start back from the store, my car won't start. So GM sent an engineer to check it out 12. icecreamallergy How did the engineer analyze the root cause of a seemingly impossible bug? Did not dismiss the issue as being impossible or the customer as being a jerk.Collected data without jumping to conclusions or offering a quick fix work around.Figured out what parameters to look for.Saw a pattern in the data.Finally he defined the problem restart interval. The rest was trivial...Define the problem, ask the right questions 13. An expert is not someone that gives the right answer it is someone that asks the right questions... 14.
