    Viruses do adapt and mutate though. Look at all the various strains of H1N1 and SARS-COV-2.

    Just because they don’t reproduce without a host cell doesn’t mean evolution doesn’t happen. If a trait emerges that is beneficial to future generations, viruses carrying that trait can infect more cells and spread further.

    Usually it’s evolution itself that people give too much agency to. Mutations are a crapshoot. They can be beneficial or they can cause birth defects, sterility, prevent reaching sexual maturity, or make finding a mate excessively difficult. Or all of the above.


  • The 3B was like peak RPi though. Nowadays unless you need the GPIO or the low power or form factor, it’s not worth it at all. You can get low-spec 3-5 year old off-lease office desktops for roughly the same price point as a top end RPi now, and they are commonplace and easily found in the secondary market.

    Hell I just bought a really clean Ryzen 5 3500 laptop for $200. Only had 8GB mem and a paltry NVMe but these are cheap upgrades if needed.









  • There’s other factors than just brushing your teeth but brushing is probably the easiest factor that most people can reasonably take control of.

    Genetics, obviously you can’t do much about. But you can avoid sweets and decide not to get pregnant (hormonal changes during pregnancy can cause mouths to get more acidic and make plaque harder to remove, and can also soften the gums and bones that hold teeth in, or even weaken the teeth directly). Also, if you want nice teeth, it’s especially important to abstain from smoking crystal meth. And that’s even more important during pregnancy.

    But telling everybody “brush twice a day for two minutes” is a small ask with huge returns.


  • Guidance for preschools around me is for them to brush kids teeth after every meal that’s served at school.

    That was recently reinstated after being suspended for a couple years and the teachers are practically (as much as they legally can) begging the parents to sign the waivers to opt their kids out of it. I don’t blame them. It seems excessive and it’d take a ton of time for two teachers to scrub a dozen or so sets of toddler teeth, while also controlling said toddlers while they wait for everyone to finish.

    The mean surface temperature of Venus is only 464C.

    But, with 93x the atmospheric pressure of earth, water boils at around 300C.

    So…what is it that makes it difficult to thrive beyond 100C? Is it strictly the temperature, or is it the properties of water at that temperature? If it’s the latter, I wouldn’t be so surprised.

    Also keep in mind that photosynthesis was a genetic accident that just happened to work really, really well, and the ability to process sunlight directly into energy was what allowed microorganisms to move away from thermal vents.

    That same genetic accident could play out in a different world. Or a different genetic accident that’s more suited to their environment. Or no genetic accident at all, and life never moves past small, very secluded regions.
