Dennis Ritchie 1941-2011

I just got the “news” that Dennis Ritchie died, although this happened on October 12… The announcement was surprisingly missing from my information channels and certainly got little media coverage, compared with Steve Jobs‘ demise. (I did miss the obituaries in the New York Times and in the Guardian. The Economist has the most appropriate heading, printf(“goodbye, Dennis”); !!!) Still, Dennis Ritchie contributed to computer science to extents comparable to Steve Jobs’, if on a lesser commercial plane: he is a founding father of both the C language and the Unix operating system. I remember spending many days perusing over his reference book, The C programming language, co-written with Brian Kernighan. (I kept trying programming in C until Olivier Cappé kindly pointed out to me that I was merely translating my Pascal vision into C code, missing most of the appeal of the language!) And, of course, I also remember discovering Unix when arriving at Purdue as a logical and much more modern operating system: just tfour years after programming principal components on punched card and in SAS, this was a real shock! I took a few evening classes at Purdue run by the Computer Department and I still carry around the Purdue University UNIX Pocket Guide. Although I hardly ever use it, it is there on the first shelf on top of my desk… As is The C programming language even though I have not opened it in years!

So we (geeks, computer users, Linuxians, R users, …) owe a lot to Dennis Ritchie and it is quite sad both that he passed away by himself and that his enormous contribution was not better acknowledged. Thus, indeed,

    printf("thanks a lot, Dennis")
