    Is there any situation where you’d want to remember the opcodes? Disassemblers should give you user-friendly assembly code, without any need to look at the raw numbers. Maybe it’s useful to remember which instructions are pseudo instructions (so you know stuff like jz (jump if zero) being the same as je (jump if equal) making it easier to understand the disassembly), but I don’t think you need to remember the opcode numbers for that.

    Edit: Maybe with malware analysis where the malware in question may be obfuscated in interesting ways to make the job of binary analysis harder?

    No, I’m not appealing to that. Fuck nazis. (I don’t actually see how my comment could be interpreted as that since my comment was in response to users complaining about having their content removed from other instances or communities, which if anything would make them the free speechers (I’m not saying that they are))

    Lemmy, in contrast to centralized platforms doesn’t force you to be restricted to the rulings of a single group of people under threat of being barred from using the entire platform.

    My point is, when you are talking on another instance, you are a guest there and it is completely expected for them to kick you out if you don’t abide by their house rules or if they don’t want you there anymore for whatever reason. While it doesn’t mean they shouldn’t be criticized for it, the impression I got from the comments on this post is that they think it is some kind attack to a basic human right to remove their comments from a foreign instance and that admins should allow all content your instance allows.

    The same can be said about the reactions people from other instances display towards news of some instance defederating from the instance they are on.

    I want to remind everyone in here that Lemmy is self-hosted and federated. If you want to make your post visible on their server or community, you have to abide by the rules they set even if they or their enforcement may seem arbitrary or stupid. It’s their server/community you want to put your stuff on and they do not have a duty to accept it. Lemmy allows you to block those communities or instances or even to create or host your own.




  • I wonder what sort of mitigations we can take to prevent such kind of attacks, wherein someone contributes to an open-source project to gain trust and to ultimately work towards making users of that software vulnerable. Besides analyzing with bigger scrutiny other people’s contributions (as the article mentioned), I don’t see what else one could do. There are many ways vulnerabilities can be introduced and a lot of them are hard to spot (especially in C with stuff like undefined behavior and lack of modern safety features) , so I don’t think “being more careful” is going to be enough.

    I imagine such attacks will become more common now, and that these kind of attacks could become very appealing for governments.


  • I wouldn’t trust ChatGPT with teaching me about some tool. It in my experience very convincingly spews out stuff it invented, and if one is still learning I can see it being hard to spot those errors. I use it to fix syntax errors in SQL queries, though, since I can’t be bothered to try understanding the not-so-helpful error messages I get with my queries, and because if chaptgpt tells a lie it will be caught by my syntax checker.

    So, I guess you can use it, if you always assume it to be trying to mislead you until proven to the contrary.
