  • Pick your favorite tech company, pick a small team with a "nerdy" engineering mandate, and I'm confident you'll find the academic, geeky science and engineering types you're talking about.

    They probably aren't very vocal though, because 1) there's a huge PR/marketing budget which is responsible for being the face of the company, and 2) well...these are nerdy STEM folks who probably like their job because they get very well compensated to be nerdy STEM types, and not because they're fanboys/girls.

  • Our experience is that basically the only really expensive thing is childcare. Are you eligible for subsidized, or free, care (or have trustworthy and willing relatives)?

    As for gear, babies don't need much. But for what they do need, reach out to friends, neighbors, and family! We're fortunate that we could have afforded everything new, but we really only bought a few things because friends and randos alike gave us so much free kid stuff (we bought a nice stroller, a baby basket, and an IKEA crib --- basically everything else was a hand-me-down). Join local "buy nothing" groups, or parent groups (sadly they're usually WhatsApp, but whatever). Most people hate throwing away stuff, and would rather it go to a good home.

    Look at programs for subsidized/free necessities like diapers. There are lots of resources out there, especially in cities.

    As everyone else said, no one feels ready. We certainly didn't!

  • So what is an easy to use or no think thing I could use a pi 5 for?

    It sounds like you really want something that works "out of the box," in which case, I would look for projects that have disk images available.

    This severely restricts what you can do with it, and as others have mentioned, is a bit antithetical to the Pi's original purpose as a tinkering machine. But you may find something you like.

    The most basic would be to just use it as a desktop replacement.

  • Does Minecraft server have a known memory leak or something?

    As a hack you can always set up a cronjob to automatically reboot at a time when you won't be using it, but not sure if that defeats the purpose of a Minecraft server...

  • Not at all in this case though! Or rather, it depends on your perspective.

    "Why doesn't electricity leak out the outlet?" is a good question, if you know nothing about electricity.

    "Why doesn't electricity leak out the outlet?" is a little stupid, if you know a little about electricity.

    "Why doesn't electricity leak out the outlet?" is a great question if you know a bit more about electricity (because it does leak out, it's just that 50/60Hz doesn't couple to freespace well unless you have a colossal antenna).

    As to this question, light in moving media: https://preprints.opticaopen.org/articles/preprint/Fizeau_Experiment_Investigating_the_Speed_of_Light_in_Moving_Media/25441108?file=45147313

  • It's a matter of perspective and use --- high density one place means you can have open space somewhere else, for a given amount of land.

    I'd much prefer a few large dense housing complexes, surrounded by green space, than suburban sprawl.

  • Sounds like maybe you want acoustic impedance ? Just like optical index mismatch, or electrical impedance mismatch, you get reflections at discontinuities. Neat stuff!

    Not exactly sure what you mean by air-water-air "dampening," but my suspicion is that you're referring to sound being reflected at each interface, so the transmission is reduced. Antireflective coating, index matching, impedance matching are all rich topics in physics and electronics!

  • 50kW class laser.

    Another source claims 1um wavelength with individual 1.5kW lasers in a hex pattern --- unclear if it's a phased array (would be awesome) or just trained on the same target (source mentions they are "combined using a mirror" so probably the latter).

    Sounds like maybe high power YAG?

  • I just want a button that rewinds 10-15s, turns on subtitles, and then turns them off when it catches up again. It's a pattern I do manually with some regularity.

    I suppose with Jellyfin/OSS, this is something I could implement myself if I was so inclined...
