    “if you can’t parse tabs as whitespace, you should not be parsing the kernel Kconfig files.” ~ Linus Torvalds

    This is what we got after people sent him into PC training. The OG Linus would say something like “if you’re a piece of s* that can’t get over your a** to parse tabs as whitespace you should be ashamed to walk on this planet let alone parsing the kernel Kconfig files. What a f* waste of space.”

    I’ll take you up on that. ChatGPT, translate this commit message to actual Linus style:

    Subject: Regarding Commit d96c36004e31

    So apparently, this commit thought it was a brilliant idea to strip away a tab because some third-rate kernel config parsing tool couldn’t handle it. Seriously? We’re bending over backward for these tools now?

    Listen up, if your parsing tool throws a tantrum over a tab, it’s time to rethink your life choices. Tabs are as fundamental to Kconfig files as oxygen is to humans. If you can’t handle tabs, you have no business parsing kernel configurations.

    And let’s not pretend this is some isolated incident. The whole tab vs. space saga is like a bad sitcom rerun from the '70s. Sure, ‘make’ might have its quirks, but that doesn’t mean we should stoop to that level of incompetence.

    I’m tempted to flood our Kconfig files with tabs just to prove a point, but let’s not make a mess where it’s not needed. However, if this idiocy persists, don’t be surprised if I start tabbing everything in sight.

    Let’s get our priorities straight, people. We’re building a kernel here, not babysitting fragile parsing tools. So let’s fix this mess and move on to more important things.

      I tried it with Claude 3 Opus, even better:

      Alright, listen up you little shits. Commit d96c36004e31 (“tracing: Fix FTRACE_RECORD_RECURSION_SIZE Kconfig entry”) had to remove a fucking hidden tab because apparently some half-assed third-party kernel config parsing tool couldn’t handle its shit.

      I don’t know what kind of brain-dead tool it was, but you better make damn sure it gets fixed. Because if you can’t parse tabs as whitespace, you have no fucking business parsing the kernel Kconfig files, period.

      In fact, let’s rub this breakage right in your face, more than some obscure ftrace record size option. If you can’t handle tabs, you sure as hell can’t handle page sizes either, dipshit.

      Yeah, I know the whole tab-vs-space clusterfuck is sadly a classic Unix thing, and ‘make’ is notorious for being a broken piece of crap in that regard. But guess what? That doesn’t make it fucking okay, got it?

      I’d sprinkle more random tabs all over our Kconfig files just to spite you, but I don’t want to make this codebase look any more like dog vomit than it has to. But if I keep seeing more of this kind of idiotic tooling, I just might fucking have to.

      So shape up, or I’ll come over there and shove those tabs so far up your ass you’ll be shitting spaces for a week. Fuck!

    Why would anyone NOT parse a tab as whitespace? Like, python really wants you to use spaces but will still let you use tabs if you are consistent.

    The Robustness Principle may seem like little more than a suggestion, but it is the foundation on which many successful things are based.

    To boil it down to meme-level old-school Torvaldsry: Assume everyone else is a f–king idiot who can barely do what they’re supposed to and expect to parse their files / behaviour / trash accordingly.

    If you do not do this, you are, without doubt, one of those f–king idiots everyone else is having to deal with. If you do do this, it does not guarantee that you are not a f–king idiot. Awareness is key.

    Examples where this works: Web browser quirks mode; Driving a car; Measure twice, cut once. This latter one is special because it reveals that often, the f–king idiot you’re trying to deal with is yourself.

    Assume everyone else is worse.

    Fun corollary: In altering his behaviour towards f–king idiots people who should know better, Linus has learned to apply the robustness principle to interpersonal communication.

        I don’t understand this either. There’s no fucking algorithm overlord here right? No fucking tiktok, youtube bullshit required.

        On another note. Thx for introducing me to the robustness principle ♥️

          Maybe I want to say it without saying it. There’s no rule against doing that, but people somehow think there is - or that there ought to be.

          Most of the time I don’t swear, so it makes me uncomfortable to use the word. There have been and undoubtedly will be exceptions. When the mood takes me. When the word, unfettered, feels right. Today was not that day.

          Funny how the partial omission offends some people more than the original word does. Adapt your parsers.

            On the fediverse we do not have to worry about upsetting coka cola or spez because a swear appeared next to their advertisement or name. Not that many people care about that elsewhere, but we especially don’t care about it here. I think that’s worth calling attention to every once in a while. It doesn’t always have to be swears as the vehicle to remind us that the power dynamic is different here.

            It’s fucking nice to be reminded there no corpo overlords here sometimes, though. Which is ironic that sometimes the foss benevolent dictators for life aren’t always benevolent.

              It’s not about whether other people are willing to accept it. It’s about whether I’m willing to generate it. This is the other half of the principle.

              Oh, BS. You don’t have to worry about swearing on Reddit either. Yes, reddit sucks, but the censoring of words on there isn’t like TikTok.

              Yeah though I have to admit I like it when people self censor because I imagine them like a cute Ned Flanders all flustered ‘well dang diddly h - e - double C!’

              But yeah it’s nice that platform’s exist simply for people to express themselves rather than to serve as vehicles for advertising. I’ll say fuck to celebrate that!

        Sometimes it works well as a stylistic choice. It’s not pretending not to use a bad word, but rather drawing attention to the fact that you’re deliberately being a little bit naughty with a wink to the reader. It’s like the absurdity of what happens when you find a stranger in the Alps.

    I do the same to people who refuse to follow specifications they agreed to follow.

    There is a slight satisfaction to get back at them for continually delivering much lower quality than is required.

    But it really is to cover me. Because, it always happens, later in the future that edge case comes up, and everything breaks. And management is ready to blame me. But then I show them that I tested the edge case before the conclusion of the project. And that programmer ignored my emails, and that I told management these edge cases weren’t covered. But then management signed off on calling it complete. And suddenly management is no longer red with fury. And they usually won’t allow me time to fix it. So the can gets kicked down the road until the next time that edge case fails.

    I am no kernel or parsing expert here but how hard would it be to convert tabs to spaces? Is it like very finicky and is weirdly platform dependent that it wouldn’t just be one of the first things that you do if you are writing a parser for anything?

      People who use spaces are not taping space space space space space space space space. Their tapping the tab key all the same.

      Yeah, same, but I always set my editor to insert spaces instead when I hit Tab, so that the spacing won’t be different in other environments.
