  • It’s not as easy to defeat as just changing the pixel…

    CSAM detection often uses existing features for image matching such as PhotoDNA by Microsoft. Similarly both Facebook and Google also have image matching algorithms and software that is used for CSAM detection which.

    These are all hash based image matching tools used for broad feature sets such as reverse image search in bing, and are not defeated by simply changing a pixel. Or even redrawing parts of the whole image itself.

    You’re not just throwing an md5 or an sha at an images binary. It’s much more nuanced and complex than that, otherwise hash based image matching would be essentially useless for anything of consequence.


  • The language it’s written in has very little, almost nothing, to do with how efficient larger applications are.

    This is almost entirely up to the design and day-to-day decisions of the developers. These almost always outweigh the efficiencies of the underlying languages themselves (within reason).

    A single location of poor data access patterns could negate the aggregate performance gains of your entire application, as an example. A framework that prevents you from making simple mistakes and drives you towards more efficient patterns goes much further than the language is written in.

    Between Rust, C#, Java, and Go you’re essentially even on performance for large applications (with C# pushing ahead of the pack). What you are not even on is engineering efficiency, it’s going to take considerably longer to build the same set of features in rust than any of the others listed. And the performance is likely the same, potentially even worse depending on the maturity of the ecosystem.

    Rust is a great systems design language and a great language to choose when developing high efficiency libraries & frameworks for I/O and data processing. It’s not really a great choice for application development due to how slow it is to actually get things done in.

    I fully expect to see alternate backends written in more operationally efficient languages over the next decade that will catch up to the official Lemmy codebase, and potentially even replace it. It actually sounds like a super fun project, funding is always a problem though.





  • Yeah, I thought it sounded unhinged. But I’m desperate, and don’t want to put myself at risk of a preventable death.

    I’ve spent the greater part of my life as a shut in largely because I’m a sniffling, coughing, sneezing mess all day and night every day for 6-8 months of the year. And simply a sniffly mess for the rest.

    I had one good summer last year and I can’t believe what I’m missing. Being able to do activities like hiking, or biking, going to the grocery store without being treated like I have the plague. Actually being able to go out to a restaurant or public places. Making friends, and actually being able to join them. Going to the movies…etc Not having to carry a whole-ass box a Kleenex with me everywhere I go.

    It made me into a desperate man, realizing how much life I’m missing.

    The comments here are fantastic, and incredibly helpful.
