UNIX is basically a simple operating system, but you have to be a genius to understand the simplicity.
We really didn't buy it thinking we'd have this enormous investment
At least for the people who send me mail about a new language that they're designing, the general advice is: do it to learn about how to write a compiler.
A new release of Plan 9 happened in June, and at about the same time a new release of the Inferno system, which began here, was announced by Vita Nuova.
At the same time, much of it seems to have to do with recreating things we or others had already done; it seems rather derivative intellectually; is there a dearth of really new ideas?
I've done a reasonable amount of travelling, which I enjoyed, but not for too long at a time.
C was already implemented on several quite different machines and OSs, Unix was already being distributed on the PDP-11, but the portability of the whole system was new.
The visible things that have come from the group have been the Plan 9 system and Inferno, but I hasten to say that the ideas and the work have come from colleagues.
I can't recall any difficulty in making the C language definition completely open - any discussion on the matter tended to mention languages whose inventors tried to keep tight control, and consequent ill fate.
Any editing, software work, and mail is done in this exported Plan 9.
For infrastructure technology, C will be hard to displace.
C is peculiar in a lot of ways, but it, like many other successful things, has a certain unity of approach that stems from development in a small group.
