  • Facebook may be evil but I don't think they're anywhere near "inject malware into global supply chains to push adoption of a public engineering side project that they don't directly profit from and most executives don't care about" level of evil. Is it possible? Sure anything is possible, but that is wildly beyond many many more plausible explanations and there's zero evidence leading us down this path. And why would they go through the trouble of backdooring zstd, which has a highly observed codebase, when they just successfully backdoored lzma because it didn't have a lot of maintainers?

    While it's true that zstd is commonly favored for having "good" compression at blazingly fast speeds, which is useful on the web and on servers, Zstd 's max compression setting (zstd --long -19) is actually within about 5% of LZMA's but faster, so it replaces most use cases of LZMA except when that extra 5% (and that's not even constant; some inputs are even better on zstd) really does matter at all speed cost

  • The first 3 seem incredibly far-fetched.

    • What exactly does Facebook gain from more people using zstd, other than more contributions and improvement to zstd and the ecosystem (i.e. the reason corporations are willing to open source stuff).
    • Why do you consider zlma to be loved among pirates and hackers and zstd not to be, when zstd is incredibly popular and well-loved in the FOSS community and compresses about as well as lzma?
    • Every person in the world uses both lzma and zstd extensively, even if indirectly without them realizing it.

    I think it's likey that, of all the mainstream compression formats, lzma was the least audited (after all, it was being maintained by one overworked person). Zstd has lots of eyes on it from Google and Facebook, all of the most talented experts in the world on data compression contributing to it, and lots of contributors. Zlib has lots of forks and overall probably more attention than lzma. Bz2 is rarely used anymore. So that leaves lzma

  • It compresses much better, by a lot, as zlib/deflate is an ancient algorithm made back when computers only had a few megabytes of ram.

    Nowadays though, zstd seems to be replacing both of them, as at max level it compresses about as well as xz while also being faster. Nevertheless, many programs link against all the common compression algorithms (xz/zlib/zstd/bz2) to support everything

  • It's useful for security researchers to collect and analyze what the newest attack bots are trying to do, in order to learn how to defend against it and study the malware they drop. There are some cool videos on YouTube about decompiling malware dropped by the bots.

    • SDL Developers Weigh Reverting Wayland Over X11 For SDL 3.0

    Jump

  • I already force Wayland global for SDL games because the xwayland one has a horrible stutter while the native Wayland works flawlessly. Making it the default sounds reasonable to me. If specific programs don't work with it, they can override it

  • Ratios that extreme would probably only be seen in cases where the source video was really poorly compressed anyway, which is what the commenter probably experienced. I've had that happen before too. Expect more like half the size compared to H264, which is still pretty good

  • At its highest compression setting (zstd -T0 -19 --long), it's about the same as lzma in compression ratio (varies a bit from file to file though), but slightly faster to compress, and much much faster to decompress. Decompression speed is not significantly affected by the compression setting (though compression speed is) and is usually at least a few hundred MiB/s to 1G+
