I run 2 SLA printers (Form 3) and print often on them. Don't get a resin printer unless you know what they're good at and specifically want that capability.

I do it routinely. It goes in a glass container that sits in water in the ultrasonic cleaner. It doesn't throw off noticeably more vapor than IPA that's just sitting open.

I run two Form 3's and run functional prototypes often. If you don't specifically need prints that are good in the way that SLA prints are good, don't get one. There's also the issue of managing and disposing of uncured resins (hello photoinitiators! we gotta keep you out of the water table!) and waste solvent. All the SLA vendors are real quiet about what you're supposed to do with the waste. "Just do whatever your local regs require."

Most blue metros in the US have a bad combination of high labor costs/low labor availability, high regulatory burden, wealthy conservative inhabitants who oppose construction, and working class people who are convinced that construction is gentrification.
I've been racking my brain trying ti figure out what it looks like for US cities to pull out of the housing crisis, and I think it's either going to take about a generation, or there will be some catastrophic event (Great Depression II, WWIII) that changes the political landscape so drastically that nobody can really oppose housing anymore.

Public housing projects were and sort of still are a thing. Glass Amendment limits the number of units that can be produced but most areas are well below those limits and the larger issue is that there's no budget or political willpower for social housing projects right now.

Hardware gets a bit easier in some respects when you have unit scale and don't need to make COGS+margin back on the sale. If Ubiquiti sell a base station, half of the unit price is gross margin. If SpaceX sell a Starlink terminal, they don't even have to cover COGS for it to be a good business case, because they're selling the service not the device.
The Starlink terminal is a very cool piece of kit, but it's not nearly as interesting as what they're hucking into LEO, and how they're doing it.

After all the LLM written or lobotomized^W"polished" writing that gets surfaced here, seeing human writing makes me want to do drugs and fall in love.

devs have really got to start using NSA style naming conventions where they use the Joycean compound with random stuff that sounds cool e.g. BANNANADAIQUIRI or FOXACID.

Thanks, I was actually trying to find this the other day. By trying, I mean I thought about it but wasn't near my phone so I forgot to do it.

Beamforming is an old technology though. It's not hard to do, just a pain to do cheaply when you've got a bajillion emitters unless you have custom silicon.

In MX and elsewhere lots of them are just mobile number through Whatsapp specifically. Like they have a phone number but it may be data-only.

1. Synonyms exist in language.
2. You're on a site with a bunch of programmers who regularly use weird words for stuff that already has a name. Reading through HN is wading through a swamp of made up names and tech neologisms, you're just used to it already. I once told a software guy that our team's SWEs had migrated away from React and Node to Stork.JS and Blackadder. He nodded like that meant anything.
3. I like it and you can't stop me.

CAFE regs made USian hugecars relatively profitable, and car makers got USians to demand them via savvy marketing. That's what I reckon anyway.

Birds adapt their song to ambient noise conditions. This paper [1] studies the Pearl River Delta (where Shenzhen is) as a natural experiment. It shows spectral changes in the target species correlating to background noise levels. I haven't looked hard enough to make sure there isn't a study that does find complexity changes but it's certainly clear that noise can affect bird song behavior generally.
