  • The most important risk you face is if somehow mains voltage ends up contacting somewhere you get electrocuted and die.

    There are 2 purposes of an earth ground: First it can be used as a reference for certain signals, such as microphones. Second, it can be used to protect against turning yourself into a sparker.

    There is a clear separation between mains voltage and system voltages so it’s typically not going to be a problem, but if a little wire ends up contacting the power supply case it can become energized and things start to get really bad.

    Most of the electrical code where I live focuses on grounding as “Bonding”, which is purely safety related for giving dangerous voltages a safe place to go.


  • It seems to me that the studying is focusing on the extent to which the life of mothers affects the life of children, particularly looking at multiple stages of life including menopause whereupon the mothers of mothers can directly contribute. It isn’t really about K vs. R, but rather understanding that primate mammals are already type K (investing more heavily in fewer offspring) what the effects of self-preservation on the mother are.

    Regarding the comment on “weird conservative ‘women are for breeding’ undertones”

    That seems like a strangely anthropocentric viewpoint. For most primates other than humans, breeding and childrearing are dominated by the females because the successful strategy for males is often to try to impregnate as many females as possible, and the successful strategy for females is often to try to have sex with as many males as possible to help reduce the chances of infanticide.

    It was with the homo sapiens larger brain and the greater negative effect on females that cooperative reproduction strategies became particularly important.


  • I don’t think that would be useful in the context of what the study was trying to understand, which is the effect of female survival on children of that female.

    The question was about the biological mother, which can be tracked because the mother gives birth. If the biological mother dies but another female continues to behave in such a way to nurture the child, then that is relevant to the analysis only insofar as the primate society took care of the child anyway which would reduce the impact of losing the mother.

    With respect to the father potentially taking on a maternal role, I don’t think the structure of many primate societies is conducive to such research, because primates are typically not monogamous. As a result, neither the researchers nor the primate fathers know who is the father of which baby, and so if a female presenting male were to “take a baby under its wing” after the death of a mother, I would expect that to be similar to a female presenting male who is not the father of the baby and so fit under the data set of death of a mother and just have the effect of flattening out the effects of the measurement.






  • I always debloat my phone, the difference is too massive to ignore.

    My last 2 phones were a Galaxy S9 and a Galaxy S10, and I really found the samsungs to be insufferable at first, but with a strong debloat removing a bunch of ‘features’ nobody asked for and redundant apps, as well as changing the launcher (I use novalauncher, but rootless is also great and also FOSS) had a notable effect on the feel of the phone. I recall that some of the “features” specifically slow down responsiveness to button pushes because for example it ends up waiting on a home button press to see if you’re going to do a double or triple press.

    If you mess it up too much, a factory restore will undo everything you did anyway, so don’t worry too much about it.

    I’ve used the same technique on a number of different phones as well. My dad loves his LG phones, but it comes with a bunch of stuff he didn’t want, so we were able to disable it. His latest phones are rugged china phones, and he swears by them, especially once we were able to get rid of a bunch of stuff they added that you really don’t need.






  • Honestly, This makes a lot of sense. Intuitively it seemed strange to me for us to just happen to be in a universe that’s barely older than the first set of stars out there, when there’s so much matter in the universe that would have needed to have formed over billions of years in the heart of stars, which would then reach the end of their life cycle and nova – that all this happens to line up awfully closely, especially with all the debris from those dead stars would need to scatter over light years of distance.
