About unwind

Bearded hacker from Sweden. Learned M68k assembly on the Amiga in the late 80s. Compiling C on a 7 MHz CPU was slow. Working as a contracting software developer since almost 10 years, enjoying visiting various parts of the software world.

I hang out a lot on Stack Overflow: http://stackoverflow.com/users/28169/unwind, mainly answering questions about C. I love C.

    Wow this is really cool! Epic to see that it has "No Man's Land" [0] and really really weird feeling to read the readme. No idea why it's listed as a "17 Bit" title though, perhaps…

    Nah I'm still against repeating the type name all over the place, and the cast adds nothing good imnsho.

    Meta: a space is missing in the title. Since this is one of the bugs, I always recommemd writing game->boardPieces = swAlloc(sizeof(ThingHandle*) * row * column); Like this instead…

    Meta: confusing typo in title. Mods , please fix penciN -> penciL. Thanks.

    Can you elaborate on how it detects and signals if it runs out of output buffer space? I couldn't see how the amount of available space was even communicated to `fc_enc()`. Also th…

    Meta; typo in title, should be "learNEd".

    This is fantastic, thank you for doing this. I hadn't thought of the poor Jaguar in ages! Heh. Found a tiny typo, this sentence from quite early (page 17): Notice how apparently wa…

    Fun post! Very happy to see a 20-something year old find and fix bugs in an X11 wm from before they were born. Gives me hope. There was some kind of editing snafu though, the loop …

    As a ultra noob in the art of knotting, I liked this when I stumbled over it a few weeks back. I agree that for newbies it would be even more instructive with smoother flows, I gue…

    Meta: This is a very messy title, it should just be "The minichord: a pocket-sized musical instrument" or something like that. We have the github info in the auto-generated blurb r…

    Reasonably, that language is MicroPython [1] which is the special pared-down version of Python for memory-constrained embedded targets. [1]: https://micropython.org/

    Just a few months back I worked in embedded development on a project and there was a physical dongle to unlock the compiler, which was surprising during on-boarding as I've spent y…

    Me too, from Firefox in Linux and no (!) blockers. Weird. Maybe geo-fenced for not being in the US, sometimes companies do that which is ... weird.

    Cool! I love seeing new games for "retro" machines, it's awesome that people keep pouring time and love into them after all these years. I'm not super familiar with 8-bit Atari mac…

    Very cool, nice effort and a good write-up! If my math is right it seems the cost in material for the printed part is around $5 which seems ridiculously cheap for a custom-designed…

    That sounded fascinating as a rather large difference in world view stemming only from using different languages. It turns out that there are various models for the number of conti…

    I think this is very cool, even though I have no historical connection to the Z80 it's of course a well-regarded and firmly entrenched/popular retro CPU. But this really is a stret…

    Which one? I did a quick search but that didn't turn up anything so perhaps it's a partial word overlap or something. I did find the projects "user-facing" home page [1] which was …

    Ah, that was a typo: you meant "GPU" (Graphics Processing Unit, not "GUI" which of course is Graphical User Interface) since that is listed in the system requirements. Explained im…

    Agreed, that really stood out as a ... questionable design decision, and felt extremely un-ergonomic which seems to go against the stated goals of the language.
