Ken Thompson and Dennis Ritchie Explain UNIX (Bell Labs)

Filed under: C Programming Language, Computer History, Unix, Video — ajlopez @ 9:14 am

I started to program in late seventies: old good days, punched cards, tape devices, big printers, teletypes. One week ago, I found this short video (promoted in Twitter after Dennis Ritchie death):

From Youtube page:

featuring UNIX creators Ken Thompson and Dennis Ritchie briefly explaining the UNIX environment. In cameo roles you’ll see UNIX luminaries Greg Chesson (in the wine red shirt) and Doug McIlroy (to the foreground of Greg). Also featured is a classic ASR-33 Teletype, BLIT displays (developed by Rob Pike, then of the Labs as well), and much more.

Simplicity: a key ingredient in Unix operating system, that won where other operating systems (like Multics) failed. After the work of these men, we discovered that a language (the C language) and an operating system could be designed and built by an small group, even by only one person.

In some sense, that Unix, that C language, are still running, under a new name: Internet.

  1. Woow, I’m kind of a fan of the good old days, of which I come too, nice video!

    Simplicity: I full agree, and could add a sentence of Dan Ingalls in Design Principles Behind Smalltalk, related to the same question:

    “Personal Mastery: If a system is to serve the creative spirit, it must be entirely comprehensible to a single individual.”

    This is probablty my favourite, because is strongly related with the MicroISV (ex-Shareware) world….hehe, yes, “Everything has to do with everything” (may be is a new Anglish expression, coming from Pancho Ibañez, do you remember, right?).

    An your last phrase is “imperdible# (room for a new Anglish word here): In some sense, that Unix, that C language, are still running, under a new name: Internet —> Yessss!
