    I think this image on the Felidae wiki sums it up pretty well: https://en.wikipedia.org/wiki/Felidae#Phylogeny

    Note that everything in this graph is extinct, except the 2 circled subfamilies at the bottom.

    EDIT: I basically know nothing about biology and paleontology and am just an amateur wiki-binger, but it seems that the half-whale was further away philogenetically from any live mammals.

    I’m guessing that the fact that this is not just some bones but a very well-preserved mummy is what makes this find special.





  • The Pomodoro method works for me. Set a timer for 25 minutes. Decide the task (or task list) you’re going to do. Make it as specific as possible, for example “write 10 ideas of things to do at work next year and rate them by how desirable and achievable they are”. Then start the timer and do the task. When the timer goes off, you have to take a 5 minute break. Whether you’ve been productove or distracted, doesn’t matter. You HAVE to take a break. Drink something, go to the toilet, reply to a message whatever. Timer goes off after 5 minutes of break time. You’ve got a fresh start to try again.

    For me, the first pomodoro is often wasted, sometimes even the first 2, but the forced break (I only have 25 minutes to a “deadline”) and mental reset afterwards help to create that setting to be productive.


  • Dangerous Waters.

    Very old style, bit clumsy on the controls, but incredibly tense with the gritty sonar stuff.

    Been only playing the P-3C airplane so far, but there’s also tons of submarines, a helicopter and a frigate.

    It is so satisfying to find and torpedo a submarines after staring at sonar graphs and dropping buoys for a while. Love it! I’ll be sharing an updated aircraft-oriented controls config when I’m happy with it, based on the one community config that was there, which was more sub-oriented.






  • Of course, if you’re living in Russia, it’s dangerous to state anything other than support for Russia’s invasion of Ukraine.

    That doesn’t mean it isn’t cringeworthy to watch someone awkwardly dance around it, trying to ignore it while complaining about (checks notes) losing a bit of reputation over an unnecessary war that their country started and which literally cost thousands of lives.

    Any Russian who stands up against that is incredibly brave. The others, just different levels of sad. Non-Russians who support Putin are the worst.

    I understand why you’d want FOSS to not care abot borders, wars and politics and that is noble. But to call this comment racism, comes across as a veiled show of support for Putin. As if critiquing his invasion is a racist act that hurts the Russian people. Putins invasion is hurting the Russian people. Not this comment.

    This has me confused.

    Temperature can be used to refer to how fast the atoms are jiggling (kinetic or phonon temperature) or to how messy, disordered (opposite of ordered) a system is.

    Time dilation is a relativistic effect where time appears to go slower when you are looking at something that has a very high speed (near light speed) compared to you (relative velocity). Can also happen with mass because gravity is acceleration, thus related to velocity.

    If the atoms are jiggling slower, relative velocities only shrink, so you’d expect to see less relativistic effect. I am not aware of any relativistic effects due to thermal motion in normal conditions (room temp, atmospheric pressure), so I don’t know how they’d appear when relative velocities only decrease.

    I am really interested where you got this temperature - time dilation link from. Can’t seem to crack it.






  • How about solidarity with other addicts? If they see you quit, they will feel pressured to also quit, have you thought about that?

    I did not realize in advance how much my quitting would hurt the other addicts.

    Not quitting fully (either still using on some days or only fully quitting the least popular parts of the addiction) seems to console them a bit.

    It’s a tradeoff you’ll have to make: do you

    • … make other addicts slightly uncomfortable by quitting?
    • … or continue to harm your health, low-wage workers’ mental wellbeing, destroy nature and the climate, contribute to pandemic risk and unnecessarily hurt the animals you consume?

    It’s not an easy choice.
