  • So… crystal ball, I don’t have access to the paper either. Think arithmetic coders as neural nets are function approximators. You send an initial token and the NN will start to generate deterministically, once you detect a divergence from the lossless ideal you send another token to put it on track again. Make it a sliding window so things don’t become too computationally expensive. You architect the model not to be smart but to need little guidance following “external reasoning” so to speak.

    The actual disadvantage of this kind of thing will be the model size, yes you might be able to transmit a book in a kilobyte (100x or more compression) but both encoder and decoder will need access to gigabytes of neural weights, and that’s just for text. It’s also not going to be computationalliy cheap, though probably cheaper than PAQ.



  • I was talking about the foundation itself, not foundation+subsidiaries. And yes ever since the writing was on the wall wrt. google funds they’ve been putting more and more money in investments to make sure they can survive, as opposed to grants. Still keeping with the foundation’s mandate, though, e.g. all their VC investments into AI are the polar opposite of what the likes of OpenAI are doing. Kinda sceptical e.g. huggingface will ever turn a profit, much less a significant one, but it’s important to have them.





  • A crawler is a data processing machine, nothing more. therefor you are disrupting dataprocessing through data. If you think its not thats ok too.

    Nah it’s definitely disrupting data processing, even though at a very low-key level – you’re not causing any data to become invalid or such. It’s the intent to harm the operator that’s the linchpin: “Jemandem einen Nachteil zufügen”. “Jemand” needs to be a person, natural or legal. And by stopping a crawler you don’t want to inflict a disadvantage on the operator you want to, at most, stop them from gaining an advantage. “Inflict disadvantage” and “prevent advantage” are two different things.

    I would still advise to contact your lawyer in germany if you are thinking about hosting a zipbomb

    Good idea, but as already said before: First, you should contact a sysadmin. Who will tell you it’s a stupid idea.




  • Casting concrete requires building formwork to cast the concrete into. For any standardised shape constructing the formwork is easy: Just assemble it from the parts you have. Straight sections? The most common case. Rounded corners? As long as you’re fine with “should be round” and don’t require some very specific radius, those are probably also at hand. A gargoyle? Well that’s not an easy form to produce but once you have it, you can cast 1000 gargoyles.

    Where 3d printing comes in is places where you have a shape that’s literally or nearly unique, where building the formwork would be a PITA. In all other cases, the traditional method is quicker and cheaper.

    Also interesting is stuff like solar sintering plain sand.

    Severely disrupting other people’s data processing of significant import to them. By submitting malicious data requires intent to cause harm, physical destruction, deletion, etc, doesn’t. This is about crashing people’s payroll systems, ddosing, etc. Not burning some cpu cycles and having a crawler subprocess crash with OOM.

    Why the hell would an ISP have a look at this. And even if, they’re professional enough to detect zip bombs. Which btw is why this whole thing is pointless anyway: If you class requests as malicious, just don’t serve them. If that’s not enough it’s much more sensible to go the anubis route and demand proof of work as that catches crawlers which come from a gazillion IPs with different user agents etc.


  • I don’t even know whether I understand I just hear MacOS users griping about fullscreen, and a quick google gave quite recent results. Especially with fullscreen being incompatible with other windows on top (each fullscreen window necessary is on its own workspace) which would be highly annoying in Blender. You can configure blender to have file open dialogues, render results etc. in its main window, but certain stuff like preferences always open a second one.


  • They don’t (usually) display the temperature but they definitely sense it, and react to it. When the sensed temperature is at or higher than the set temperature, the valve will be closed, if it’s lower it will be opened. Mere valves can’t do that.

    That’s what a thermostat is: A negative feedback control system regulating sensed temperature towards a setpoint, and keeping it there. They’re simple, inexpensive, reliable. Yes having the temperature sensor right next to the radiator isn’t ideal but unless the room is quite large that’s not an issue. Also with large rooms you probably have more than one heater and thus thermostat. And you could, in principle, put the thermostat far from the heater but I’ve never seen that done.






  • What are you trying to argue, that humans aren’t Turing-complete? Which would be an insane self-own. That we can decide the undecidable? That would prove you don’t know what you’re talking about, it’s called undecidable for a reason. Deciding an undecidable problem makes as much sense as a barber who shaves everyone who doesn’t shave themselves.

    Aside from that why would you assume that checking results would, in general, involve solving the halting problem.
