  • Coal plant burns coal to heat water, makes steam, and the steam powers a turbine to produce electricity. A nuclear power plant uses nuclear fuel to heat water and produce steam similar to a coal plant. It may do this indirectly (e.g. second loop between the nuclear fuel and water loop to prevent the water becoming radioactive). This means that to build a nuclear plant you essentially need to build a coal plant, and then also the nuclear reactor and safety stuff, which makes them more expensive. Since coal plants are being turned off anyways, it might be more cost effective to just retrofit old coal plants so the only cost is the nuclear reactor side of things (plus any necessary maintenance and upgrades)


  • Also if you want a domain but dont care about the actual address, a .xyz domain composed entirely of numbers with less than 10 digits is $1-2 + same as renewal fee per year. $1.22 for me on porkbun

    Just be sure to redact the whois information bc you will get a call from scammers trying to get you to register your domain on some “internet map” for a small fee acting as if its some step in your setup process you havent done yet









  • I felt the same the first time I tried but it honestly takes a few tries to start getting it right. The kind of iron and solder matter a lot; the older ceramic core ones suck and the JBC/pinecil type are much superior. Part of the problem with the ceramic type ones is they have one setting - full blast - and not good temperature control. With a pinecil/JBC you can set the temperature to 300C and expect to get 300C. Too hot and it will boil off the flux before you’re done soldering and you just get crud.

    In terms of solder, leaded rosin core solder is the best. Don’t worry about the lead, as long as you wash your hands. Use a brass sponge type thing to clean the tip frequently to remove crud

    For through holes, I’d say get some veroboard off eBay and a bunch of cheap resistors and just start plugging away until you get better. Process is basically - have tip with a bit of solder, poke to pad and pin, put solder into joint and hold 1-3 seconds until solder flows onto pad and pin, remove tip. Putting some flux on in advance helps remove the oxides before soldering

    For surface mount (side pads/pins), there are kits with cheap/obsolete/trash components you can just plug away at without fear of messing anything up. Soldering smt is a bit annoying but doable by hand without much training. the process is basically: tin one pad, use tweezers to place part and reheat the solder until the part is in place, solder the rest of the pads, reheat first pad to relieve stress.

    Even for large parts, I used to have trouble with unsteady hands. If you are doing smt you really need a microscope or magnifying glass for anything smaller than 0805 - really helps with the visual feedback loop for hand positioning. A microscope significantly improved my dexterity and hand steadiness



  • What kind of emails are you sending to what kind of people, and how frequently that AI increases your productivity? I don’t think I ever have emails that AI could do better or faster, since it’d probably take longer to explain to the AI what I need it to write than to type it out myself. Then again I’m in an engineering setting and it’s pretty much just numbers, confirmations, basic requests, and issue descriptions, IT tickets, mostly

    In was looking for a small space heater for the bathroom because it gets so cold in the morning. There was one that was a plug in into the outlet kinda like a night light, and had a temperature display. There was a one star review along the lines of

    This thing is garbage! It just keeps saying nonsense like 9L! Needs better instructions!
