  • I haven’t seen the ads to have any idea about this person, but I will but from the stores.

    GameStop very rarely, because a game console store price is dumb and getting a used copy of a popular game is cheap, but overwhelmingly will get/wait for PC editions of games, so it comes up very rarely.

    Best buy I’ll buy something because they frequently are competitive with buying online, and I like the ability to just pick something up now without waiting. Also when a controller has an issue or was similarly instant to exchange. Didn’t wait a few days just to get a botched one and then wait a few days for a replacement, got it, find out of was not working, and exchanged it all in the same day.


  • While technically the truth, it can be a hassle to make sure you restart all relevant services after updating a given library.

    I just like being able to restart underlying system to take care of any possible straggler without thinking, and the services broadly be provided by multiple systems so the “experience” is starting up through a rolling reboot


  • So assuming 10 lbs of force, as measured 1 meter away from the hinge, you have about 44.5 Nm of torque. Assuming each door opening was about 90 degrees, then you have about 70 Joules per door operating event.

    Each door opening would have a physical theoretical max of 0.02 watt-hours.

    Assuming you spent 8 hours opening a door every 10 seconds constantly, then you have 58 watt-hours of energy at the end of the day if you had 100% efficient generators. One typical solar panel would hit that in under 15 minutes in real-world energy collection, not theoretical.


  • So yes, the law says there is some unavoidable, unusable waste heat, the question is how much of that heat is really unusable?

    For example, you have lava at around 1,000 degrees. You certainly can harvest energy from that, hit some water with it and spin a turbine.

    For the most part, once we get under 100C we run out of ideas on how to realistically harvest energy out of it, but there’s still a pretty good delta between that an ambient. The claim of this article is he has an approach to harvest energy at an even lower temperature delta.

    If it got to harvesting all of the temperature delta of a system, then we can say “not at all possible based on current understanding of physics”, but if the process leaves some waste heat unharvested, then it’s not yet violating that law. The law just says it gets less and less likely as the amount of heat in question diminishes.






  • The type of problem in my experience is the biggest source of different results

    Ask for something that is consistent with very well trodden territory, and it has a good shot. However if you go off the beaten path, and it really can’t credibly generate code, it generates anyway, making up function names, file paths, rest urls and attributes, and whatever else that would sound good and consistent with the prompt, but no connection to real stuff.

    It’s usually not that that it does the wrong thing because it “misunderstood”, it is usually that it producea very appropriate looking code consistent with the request that does not have a link to reality, and there’s no recognition of when it invented non existent thing.

    If it’s a fairly milquetoast web UI manipulating a SQL backend, it tends to chew through that more reasonably (though in various results that I’ve tried it screwed up a fundamental security principle, like once I saw it suggest a weird custom certificate validation and disable default validation while transmitting sensitive data before trying to meaningfully execute the custom valiidation.







  • It’s certainly a use case that LLM has a decent shot at.

    Of course, having said that I gave it a spin with Gemini 3 and it just hallucinated a bunch of crap that doesn’t exist instead of properly identifying capable libraries or frontending media tools…

    But in principle and upon occasion it can take care of little convenience utilities/functions like that. I continue to have no idea though why some people seem to claim to be able to ‘vibe code’ up anything of significance, even as I thought I was giving it an easy hit it completely screwed it up…


  • So if it can be vibe coded, it’s pretty much certainly already a “thing”, but with some awkwardness.

    Maybe what you need is a combination of two utilities, maybe the interface is very awkward for your use case, maybe you have to make a tiny compromise because it doesn’t quite match.

    Maybe you want a little utility to do stuff with media. Now you could navigate your way through ffmpeg and mkvextract, which together handles what you want, with some scripting to keep you from having to remember the specific way to do things in the myriad of stuff those utilities do. An LLM could probably knock that script out for you quickly without having to delve too deeply into the documentation for the projects.
