Dik Winter

Discussion in 'C Programming' started by Ben Bacarisse, Jan 5, 2010.

  1. I have just heard the sad news that Dik Winter died on the 28th of
    December, a couple of months before he was due to retire.
    http://www.cwi.nl/en/2009/1044/Dik-Winter

    Since he was a frequent poster here, I though you'd all like to know.
    My apologies if posts like this are not appropriate.

    I'm so sorry to hear that. His contributions here will be missed.

    That's a real shame. I didn't know him, but his contributions were
    valuable and I'm sure he had earned a long and happy retirement.

    To make this vaguely topical, it's a loss to the C development community
    for the advice he could have contributed.

    Thanks for passing that on. I always enjoyed Dik's posts as so
    many had a numeric bent, which is my field of greatest interest.
    In other newsgroups, he was one of a tiny handful of posters to
    whom I gave a positive score, so that I could zip straight to
    interesting posts. A grave loss to this and several other groups
    and communities.

    Dik was een goed persoon, goed geïnformeerde met C, patiënt in het
    onderwijs, en strikte contra-voorbeeld voor mijn stelling dat alle
    Hollanders op het internet zijn klootzakken.

    Sad news. He was certainly one of my favorite posters to read.
    His mathematical insight was wonderful, and his numerical experience
    without par among those that post here.

    Damn!!! Dik has posted on Usenet for at least the last twenty
    years, and certainly has added to the useful and interesting
    content. While I *never* knew Dik personally, my life has been
    diminished by his passing. He was a "straight up" kind of guy and
    there are *not* many like that on Usenet.

    In the early 90's, I posted a question about calculating the value
    of pi, and Dik posted the following program. (I do *not* know if
    he originated it, but I found it interesting.) You can compile and
    run it:


    int
    a=10000,b,c=2800,d,e,f[2801],g;main(){for(;b-c;)f[b++]=a/5;for(;d=0,g=c*2;c
    -=14,printf("%.4d",e+d/a),e=d%a)for(b=c;d+=f*a,f=d%--g,d/=g--,--b;d*=b);}

    also sorry to here this. Whenever there was a discussion about
    numerical maths I'd perk up my (metaphorical) ears when I saw Dik
    Winter was posting "aha! now we'll find out what the real answer is!".
    He seems to have programmed some odd machines in his time! And seen
    the wierdest floating point formats. And he appeared to know an awful
    lot about Algols.

    Oh, and he was nice to people!

    Sad news. We lost someone who loved his craft and was good at it.
    He last posted here on 21 Dec. Dik will be missed.

    Arndt credits something practically identical to this but a bit shorter
    (there have been many variations), to Dik Winter and Achim Flemmenkamp.

    That is, indeed, very sad news. He was one of the few posters to this
    newsgroup who commanded _real_ respect.

    A good point. I should stop posting while in a bad mood. :)

    Dik helped me in the "setting to zero" thread in Sep. Maybe he also
    gave help to me in other posts which i can't remember and can't find.

    I saw Dik's name in this group for many many times before.

    Thank you.

    Sad news - a valuable contributor to this group who managed to float
    above all the bullshit and provide useful information without prejudice.

    FFS! The poor guy has just died and you're still worried about tiptoeing
    around the topicality zealots. Let them fume if they like while those of
    us not completely cut off from common humanity reflect on his
    contribution.
