  • I used to use KGS, but that was mostly on the computer, though I know they also have an Android app. That was several years ago, though. My friend who still plays does so mostly on Pandanet via Android.

    Those are both for multiplayer, of course. For single player, a while back I used Gridmaster along with a build of LeelaZero, and there are various apps that offer Go problems, including one my friend likes, but I have forgotten what he told me it was. I think it might be Tsumego Pro, but I’ll have to ask him again next time we talk.

    Edit: Dragon Go Server probably deserves a mention as well. That’s a site for, basically, postal games via email, and can be accessed entirely via a web interface. It’s not as popular as the sites with faster time controls, but it’s kinda nice for playing a leisurely game with a busy friend.




  • It looks to me like they did it this way so that it could have natural-language names in many languages. So, the function Z10096 is called “is palindrome” in English, but if you’re coding in Japanese you can call it “回文の判定”. I don’t think the idea is for people to refer primarily to the alphanumeric soup version; I think that’s just the unique identifier for the database.

    It does look like it’s leading to some issues, though. E.g., someone added a test for the “is palindrome” function which uses a somewhat common example: “Straw? No, too stupid. I put soot on warts.” Now, a human would probably say that this is a palindrome, because it’s got the same letters forwards and backwards, but most of the implementations disagree, because they consider the spaces, capitalization, and punctuation to be part of the string; that is, they test whether the input string and its reverse are equal. So someone (possibly the same person) has added a second python implementation which ignores spaces, capitalization, and punctuation, and mentions that in its name on the page.

    Fundamentally this function is solving a different problem than the others (as demonstrated by the differing results on the relevant test), so should it get its own number and page? should there be a “palindrome disambiguation” page? This seems like something the site will have to figure out how to handle.


  • Turbo Pascal was the first language in which I had serious classes (I had tutoring in Applesoft Basic earlier on, but that language has a lot of limitations), and I used it for years afterwards. You could write auxiliary functions in Turbo Assembler and link them in; I used that to write a library that allowed access to the 320x200 256-color VGA mode (the built-in graphics only did EGA and were super slow), and other libraries for mouse and joystick control. I tried to control the soundblaster for FM synthesis, but it was too complicated for me to figure out how to do anything useful without better access to documentation (this was before the world wide web). The experience also taught me a lot about assembly language basics, function calling conventions for C and Pascal, stack manipulation, and so forth, which gave me a huge head start in my compilers courses at university.

    On the whole I would still recommend C over Pascal as an early language–it gives you much better insight into memory layout and so forth, where Pascal kind of obfuscates such things, and C just generally kind of acts like both Pascal and Assembler rolled together. But Turbo Pascal definitely gave me a good foundation.








  • 3blue1brown is a great call.

    I would add Applied Science and NileRed (who does chemistry experiments) as possibilities if OP likes their voices. Their content is very methodical and uniform. My cat likes their videos, which seems like a pretty good metric for this use case.

    I also love vihart, who does math videos, but her stuff is a little more varied, including some music, so OP might want to evaluate her during the day before trusting her channel for sleep.

    Jeremy Fielding has a great voice if you want videos about engineering and how to salvage motors out of washing machines and treadmills.

    I’ll consult my subscription list and add more if I find any.

    Edited to add:
    Carl Bugeja (electronics)
    CGP Grey (mostly history)
    DIY Perks (various projects)
    Henry Segerman (math art)
    OskarPuzzle (designs for 3d printed puzzles)
    Razbuten (video games)
    Sabine Hossenfelder (physics)
    Stand-up Maths (math)
    Steve Mould (explanations of unusual everyday things, I guess? kinda hard to summarize)
    Technology Connections (as others have mentioned)
    Tim Hunkin (makes weird mechanical art and explains machines)
    Tom Scott (videos about unusual places and bits of history)
    Two Minute Papers (advances in AI and computer graphics)

    Edited again to add: Breaking Taps. This one is mostly microscopic fabrication stuff, so, various kinds of microscopes, vapor deposition, etching, etc.
