  • Whoops! When I looked at the second time that the shift value is calculated, I wondered if it would be inverted from the first time, but for some reason I decided that it wouldn’t be. But looking at it again it’s clear now that (1 - i) = (-i + 1) = ((~i + 1) + 1), making bit 0 the inverse. Then I wondered why there wasn’t more corruption and realized that the author’s compiler must perform postfix increments and decrements immediately after the variable is used, so the initial shift is also inverted. That’s why the character pairs are flipped, but they still decode correctly otherwise. I hope this version works better:

    long main () {
        char output;
        unsigned char shift;
        long temp;
        
        if (i < 152) {
            shift = (~i & 1) * 7;
            temp = b[i >> 1] >> shift;
            i++;
            output = (char)(64 & temp);
            output += (char)((n >> (temp & 63)) & main());
            printf("%c", output);
        }
    
        return 63;
    }
    

    EDIT: I just got a chance to compile it and it does work.


  • I first learned about Java in the late 90s and it sounded fantastic. “Write once, run anywhere!” Great!

    After I got past “Hello world!” and other simple text output tutorials, things took a turn for the worse. It seemed like if you wanted to do just about anything beyond producing text output with compile-time data (e.g. graphics, sound, file access), you needed to figure out what platform and which edition/version of Java your program was being run on, so you could import the right libraries and call the right functions with the right parameters. I guess that technically this was still “write once, run anywhere”.

    After that, I learned just enough Java to squeak past a university project that required it, then promptly forgot all of it.

    I feel like Sun was trying to hit multiple moving targets at the same time, and failing to land a solid hit on any of them. They were laser-focused on portable binaries, but without standardized storage or multimedia APIs at a time when even low-powered devices were starting to come with those capabilities. I presume that things are better now, but I’ve never been tempted to have another look. Even just trying to get my machines set up to run other people’s Java programs has been enough to keep me away.








  • Looks very interesting, thanks for posting!

    Watching the video and reading the blurb, I immediately got some Panzer Dragoon vibes (a lone hero riding a flying mount, an evil empire hoarding ancient technology, biomechanical weapons, lots of airships, Moebius-influenced visual design, Celtic touches in the music), and looking at reviews, some other people have picked up on that too. But it’s not a bad thing; the (solo!) developer seems to have borrowed a few parts of the franchise that they liked and run in a fairly different direction with it overall.


  • Did you read all the way to the end of the article? I did.

    At the very bottom of the piece, I found that the author had already expressed what I wanted to say quite well:

    In my humble opinion, here’s the key takeaway: just write your own fucking constructors! You see all that nonsense? Almost completely avoidable if you had just written your own fucking constructors. Don’t let the compiler figure it out for you. You’re the one in control here.

    The joke here isn’t C++. The joke is people who expect C++ to be as warm, fuzzy, and forgiving as JavaScript.








  • Let me know if you find one that uses AI to find groupings of my search terms in its catalogues instead of using AI to reduce my search to the nearest common searches made by others, over some arbitrary popularity threshold.

    Theoretical search: “slip banana peel 1980s comedy movie”
    Expected results in 2010: Pages about people slipping on banana peels, mostly in comedy movies, mostly from the 80s.
    Expected results in 2024: More than I ever wanted to know about buying bananas online, the health impacts of eating too many or not enough bananas, and whatever “celebrities” have recently said something about them. Nothing about movies from the 80s.


  • As someone who has often been asked for help or advice by other programmers, I know with 100% certainty that I went to university and worked professionally with people who did this, for real.

    “Hey, can you take a look at my code and help me find this bug?”
    (Finding a chunk of code that has a sudden style-shift) “What is this section doing?”
    “Oh that’s doing XYZ.”
    “How does it work?”
    “It calculates XYZ and (does whatever with the result).”
    (Continuing to read and seeing that it actually doesn’t appear to do that) “Yes, but how is it calculating XYZ?”
    “I’m not 100% sure. I found it in the textbook/this ‘teach yourself’ book/on the PQR website.”
