    If your plan is to not review and just have the LLM rewrite if it doesn’t work, it doesn’t sound like the rewrite is gonna be any better.

    It doesn’t have to be an intentional threat to be worth responding to. One might reasonably think they’d stumbled on an (admittedly poorly executed) attack.

    Is it a taboo, or is it just reserving specific words to mean specific things and insist everybody be precise about it?

    This really depends on context. Sure, if you're responding to a forum post or StackOverflow question with nothing but the LLM output, then I agree with this. On the other hand, whe…

    I don't think these things are as different as you think. I started at "ls" and worked down. If you work up, you get things like a "socket", an "object" within a programming langua…

    I’m curious what you think an abstraction is. Even running “ls” involves several layers of abstraction: a shell, a process (abstracts memory), a thread (abstracts CPU)… you think i…

    Is the MET right? They launched about 29 hours ago but it says 1d18h

    Thanks for the context. That makes a lot of sense! Those three constraints seem pretty important and a useful way to think about the problem.

    Having used Rust professionally for six years now, I share your fear. Like many of the commenters below, coherence just hasn't been a big problem for me. Maybe there are problem sp…

    I've never once pulled in a new dependency and had the program fail to compile just by virtue of that dependency being present [because both my code and the new code both impl'd th…

    I don’t think that sums up the post well. I would say: The phrase “it turns out” has a surprising way of disarming skepticism in readers. While surprising, it’s easy to understand:…

    I inferred that they’re referring to the fact that in typical C the compiler must have seen a function earlier in the file for you to use it. One solution (that the author doesn’t …

    Doesn't this depend a lot on how long your actions run? Like, you may have already invested in your own hardware (maybe because your actions use a lot of resources and it's cheaper…

    It is, although you can have sharded PostgreSQL, in which case I agree with your assessment that you want random PKs to distribute them. It's workload-specific, too. If you want to…
