  • Welcome to EU! Prepare for a cultural shift:

    Considering that everyone on lemmy is 30+ communist tech worker, it’s probably a welcome change

    Speaking more specifically about Poland, depending on how you measure, we might have the most rapidly secularizing society in the world Some Americans (catholic fundamentalists) seem to think that you can just barge in, snatch a tradwife and plot of land and live like it’s 50s, but these people are straight up delusional. Introducing ban on abortion, for example, erased full quarter of support for the party that did it (40% ish to 30% ish overnight) and caused largest protests since dissolution of Soviet Union. There are conservative women, but these tend to be 60+

    In tech job market specifically, the bubble has ended (like everywhere else i guess), but if you’re a senior or able to keep your current job you’ll be fine (not sure how you’d get residence permit then). You’d need to lean Polish as a practical matter, because while lots of people do speak decent English, many don’t (esp. 50+ and in small towns) and many official matters can be done in Polish only. Like everywhere else, there’s division between more conservative rural areas and more liberal large cities; no one wants to live in the former, even locals, and so most of foreigners live in Warsaw (or Kraków, or Wrocław). It sounds like you’d blend in right away in one of these places. While property prices and rent went up since start of the plague, it’s not as crushingly bad as in, say, Berlin or Rotterdam. Random benefits include ability to pirate absolutely everything without VPN with no consequences and ability to use complaint as a conversation starter











  • Electoral college is fucking weird

    That you disallow prisoners to vote, but a felon can run as a candidate

    That you end up in situation where there are hours long lines and you don’t have one station per, say, 1000 people at most

    Registering to vote is weird, but that is i understand mostly a consequence of not having countrywide ID standard. In my country you’re automatically registered where you live, and IDs are free of charge and mandatory to have (not driving license or passport. there are fees for these)

    Election isn’t on weekend, there’s zero reason why it couldn’t be or it could be made national holiday. There was even free public transit for election day in my city, but that one was paid by the city

    That some of people (republicans) seem to be into politics in the same way ultras seem to be into football, it’s still fucked up but i’ve seen it in other places so it’s not that weird by now



  • what neutrons? we’re talking about shielding of spacecraft moving out of earth’s magnetosphere, not a spacecraft travelling through core of active nuclear reactor

    the kind of radiation that is relevant are high energy protons (and alphas and electrons, with a sprinkle of heavier nuclei) from sun, mostly. there’s no relevant source of neutrons

    (and incidentally water is pretty good at absorbing neutrons too)

    water does not expand upon irradiation, what the fuck are you talking about. you can’t reflect high energy protons (what would be important in radiation in interplanetary travel) you can only either absorb them or let them pass, there’s no third option, same for anything above uv and electrons

    to a first approximation (rather good one at that) (for gammas) absorption is proportional to how much mass per area unit is used as a barrier. 1 g/cm^2 of water is just as good barrier as 1 g/cm^2 of lead or steel. this means that you can absolutely use completely normal, regular potable water as a radiation shield

    Water in its purest form would have to take on mass to “absorb” radiation, expanding a hull and destroying it over time.

    i’m not even sure what it’s supposed to mean, unless your understanding of ionizing radiation is uncut nonsense

    chemically speaking, it’s completely fine to irradiate water because whatever is formed as a result of radiolysis would just most of the time form water back, with the rest becoming very weak solution of hydrogen peroxide. this is big part of the reason why water is used as a coolant in nuclear reactors

    there are also specific nuances to stopping anything that is not gammas, like secondary x-rays, gammas from neutron absorption etc and this actually favours light element shields, like water or liquid hydrogen, for this kind of radiation shielding
