   I'm not (yet) advocating we all program in K, but we start with the simpler problem of trying to talk about programming like scientists: To try to define things only in terms of what we can measure. The speed at which code runs? The si

   I didn't use the word "superfluous". I define code bloat strictly as redundant code inside the source tree. Car manufacturers do not exist inside the source tree. They aren't even obviously unnecessary; After all, people

   It is interesting. Can you talk more about context? How exactly does it help you? I don't think: c::a$"\n";b::0,1+c;d::(#c),|/-':b / (c)uts, (b)egins, (d)ims is more clear than: c::a

   I'm sorry: It wasn't an intentional dodge. It really was getting late in the day. Only one person was hostile. They wanted to point out that there was no point in writing it all on one line "just to be unreadable". I tol

    kOS is K5; it's as different from K4 as K4 was to K3. Views are available in K4/Q/KDB+, so the version on kx.com does work with views. If you want to play with the views idea, try to solve a problem and see where a view helps

    kOS doesn't use the Linux kernel code. It supports a few of the same syscalls: clone, execve(!), epoll_create, epoll_ctl, epoll_wait, dup2, stat, rename, unlink, getcwd, chdir, fstat, getdents, open, close, read, write, ftruncate, mmap

    Sean wasn't making points. He was being obtuse and dismissive, and made repeated statements about the author and how much he was laughing at the idea that this was being read by anybody. I read it: I enjoyed it. I didn't run into

    I've always understood the origin of the "10x programmer" was about overall performance, and not mere "time-to-type". That is: we're talking about the reported value of the employee to the company. In that way,

    That only means instantaneous productivity isn't useful. Fortunately most employers know this: The employer pays for a mean-productivity-over-time. If your productivity falls below that value you will get fired, and if it exceeds some

    Except someone can be married and divorced multiple times (even within a single year). Counting the marriages or the divorces is a mistake. You need to count the people over time, but also not consider people who never get married.
