    Well it is compiled to byte code in a first step, and this byte code then gets processed by the interpreter. Now Java does the exact same thing: gets compiled to byte code which then gets executed by the jvm (java virtual machine), which is essentially a interpreter that is just a little simpler than the python one (has fewer types for example). And yet, nobody talks about a java interpreter


  • Yes. But the more advanced LLMs get, the less it matters in my opinion. I mean of you have two boxes, one of which is actually intelligent and the other is “just” a very advanced parrot - it doesn’t matter, given they produce the same output. I’m sure that already LLMs can surpass some humans, at least at certain disciplines. In a couple years the difference of a parrot-box and something actually intelligent will only merely show at the very fringes of massively complicated tasks. And that is way beyond the capability threshold that allows to do nasty stuff with it, to shed a dystopian light on it.


  • In terms of helluvalot less critical - is it really though? Remember that the app on your phone is also witten by them, closed source and does whatever they want with your clear-text messages. If the trustworthyness of a messaging vendor is part of the critical-ness question, e2e encryption does not add anything: Either you trust them and could also do so when they process your message on their server, or your don’t and they could indeed spy on you on the proprietary client app.

    End 2 end encryption is only a real benefit when the ends actually belong to the user, i.e. theres transparency about the ends being clean, which can only be shown for open source ends. If the ends are potentially compromised, there’s so security / privacy guarantee.

    One additional counter measure that is not mentioned in the article is doing a slight z-hop (like half the layer heigt) for travels. That can help prevent depositing the ooze-drop along the travel move, given that all other mitigations are in place and the ooze-drop is small enough. Do not hop very high, because the vertical lift will pull strings out of the nozzle otherwise.



  • There is a lot of bogus “science” out there, and this is part of it.

    You need a temperature differential to harvest electric energy. You also need a differential to get heat energy to flow (usually from inside your apartment to outside). If you have that differential, you do not need an AC, you just open the window. If you do not have a differential (or if it points the wrong way, i.e. outside is hotter than inside), you need an AC + energy to create that differential, that lets thermal energy flow from your room to outside. There’s no “free leftover differential” in this, the differential it creates is literally to transport heat energy = why you have turned on the AC. Every bit you use of this differential for harvesting energy, you could turn down the AC a notch and have it save more energy than you could possibly harvest.

    This idea is as mute as mounting a wind turbine to your electric car to “harvest” the headwind from driving


  • Heat pumps (like AC units, fridges, etc) become less efficient the greater temperature difference they have to pump the heat. So pumping heat from a 25°C room to a >100°C steam engine would become terribly inefficient. It would need more energy, which creates more environmental damage and climate crisis to source, and that energy heats the cities even more.

    The only sane way to cool cities is to get rid of as much concrete and asphalt as possible (especially the vast amounts of ground that is covered for cars), and keep only narrower sealed paths for small individial transport like bikes. Plaster everything with trees and grass and other greens. They cool down the city dramatically and are able to take up the water that comes down at extreme weather events.

    Escaping the urban hellscape cannot be achieved by building more stuff and throwing more energy at it. Just visit a park in your city and observe how the temperature changes, it is that simple. Mobility cannot seal all surface area, it has the be minimal, i.e. narrow paths and trains with rails that can also run on open ground / green areas. This implies of course not building secluded areas for living, shopping, working etc… It has to be a mix, where commutes are short (i.e. like european cities, not american ones).
