  • how many ways can you really communicate with a cell tower?

    Analog encoding assigns each device in a cell its own frequency range.

    Time-domain multiplexing assigns each device a fraction of a second to transmit.

    Quadrature phase-shift keying alters the timing of a signal to convey data.

    Orthogonal frequency-division multiplexing has each device transmit the same signal over P out of Q bands, such that each device’s signal can be reconstructed by knowing which bands it transmitted on.

    There’s a fucking reason your phone is faster now than in 2010.




  • Possibly the final version. Quite Okay Imaging (QOI) achieved similar compression with none of the complexity. Lossy + difference = lossless formats are surely the better option where performance is not crucial. Even the fact they fffucking finally made APNG official is decades late to replace GIF, since several image formats are now literally video formats.

    The future is webp. And telling software patents to burn in hell.









  • Evaporative cooling is a bitch. You have some community about the problems with X, and there’s a range of opinions about how bad X is. Anyone mildly affected won’t post much or stick around. People with intense opinions exaggerate. Whether it’s for comedy or rhetoric, ‘X will be the death of us all!’ chases out even more mild users. Now you have a vicious circle of X haters.

    If that’s popular enough to form a meaningful audience, you see careers made, serving that conclusion. Shockingly few of them are grifters. They just posted something honestly critical that the haters really enjoyed, and the likeminded engagement made the author’s brain do the happy chemicals, so now they’re the weekly go-to for obsessively complaining about the evils of X. Still naming any actual problems with X, on par with their original independent criticism… but in the new fire-breathing style that makes even half-true non-issues sound like the worst event in recorded history.

    The same can happen for positive attitudes, but the result is less circlejerk, and more… cult. Like that DRSyourGME instance. Or Qanon. When sensible people start toward the exits, that doesn’t mean the party’s over.


  • Rule: No comparing artificial intelligence/machine learning to simple text prediction algorithms.

    That’s an overstep. “Spicy autocorrect” is not a joke exclusive to trolls. LLMs genuinely are simpler than they have any right to be, and it’s ridiculous they work anywhere near this well.

    Then again, rigidly defining bad behavior is a poor move anyway, when you’re trying to say “don’t be a tedious asshole.” Tedious assholes will gladly slip around whatever specific problems you name, and bait other people into unwitting violations. The general version of this is enforced civility, i.e. “Rule 1: Be nice! >:(”, and that becomes a duck-blind for infuriating liars. Sometimes “fuck off” is a perfectly reasonable response.

    Just write “don’t be a tedious asshole.” Hash out what that means amongst the mod team. Do not be afraid to give people a week-long time-out for things you did not pre-emptively wag a finger about. If they mewl ‘but it didn’t say!,’ tell them, it doesn’t have to. I think everyone is happier when they can trust moderators to make a judgement call on who’s being a dick. And so long as the stakes are temporary, don’t be afraid to get it wrong sometimes.
