    my website’s backend is made with bash, it calls make for every request and it probably has hundreds of remote arbitrary code execution bugs that will get me pwned someday, it’s great

    edit: to clarify, it uses a rust program i made to expose the bash scripts as http endpoints, i’m not crazy enough to implement http in bash

    it behaves like a static file server, but if a file has the others-execute permission bit set it executes the file instead of reading it

    it’s surprisingly nice for prototyping since you can just write a cli program and it’s automatically available over http too






  • Peanuts and dairy are usually possible to spot without checking the ingredients list, and they serve a distinct culinary purpose. They have valid reasons to exist, and are fairly simple, if a little annoying, to avoid.

    HFCS does not serve a distinct culinary purpose (it’s pretty much just sugar but it benefits from corn subsidies), and is impossible to identify without careful scrutiny because it’s included in all sorts of foods that it has no business being in. The (purely financial) benefit it provides is far outweighed by its harm to public health.




  • My big killer feature for Linux phones is running Wayland/X11 apps mostly unmodified, if AOSP added support for that I wouldn’t be too disappointed about sticking with it. I’ve tried to make android apps before, but doing things the Android Way™ basically requires you to use java and their bespoke UI primitives, and it always makes me wish I could just use the tools I’m already used to.

    Being able to have intricate control over my phone is nice, but I’d rather do it with a KDE-like settings maze than a terminal because of how tiny the screen is, and if I’m doing something serious that would require a terminal I would rather do it at my desk.

    I definitely think the Android ecosystem has some serious problems, but I already run a custom ROM without Google Play Services installed so I’m fairly well-insulated from that. I do plan on installing a mobile Linux system on my old phone to experiment, but I doubt it will become my system of choice.



  • Some games use a “trust” system based on human reviews of your gameplay that affects how you are matched with other players, but there isn’t a respectful way to force people to use just one account so that the trust score can follow the person. The best way I can think is to tie the purchase of the game to that account, which many services do, but that breaks the used games market…


  • There’s a concept I call “rule zero of cybersecurity”: “the user can and will exploit trust you place in them or anything they can touch.”

    You can make it more difficult to exploit the trust you put in the user by hiding it behind obfuscation, but ultimately the user can desolder your secure enclave, reverse engineer your anti-tampering measures, and falsify any check your program wants to do, if it happens on their computer.

    Client-side anticheat on Windows doesn’t “work” in the pure sense either, it’s just enough of a pain to bypass that most people don’t because you can’t recompile the kernel to change how it behaves. On Linux, it’s easier to take advantage of the fact that perfect client-side anticheat is fundamentally impossible.

    Same with device attestation, DRM, and other client-side verification measures: they’re doomed to be in an endless back-and-forth because what they’re trying to do is fundamentally incompatible with reality.

    The correct choice for anti-cheat is to detect cheaters like humans do: watch a player’s actions as they are received by the server, and use your knowledge of typical player patterns to detect if the player is cheating. Your server’s knowledge of the network messages coming from the user’s computer is the only thing you can trust (because it exists on hardware you control), so you should make your decision by analyzing that.
