  • 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.














  • I feel you. What helped me was learning about growth mindset and fixed mindset. It doesn’t magically cure it, but it does help to know why you feel that way and how untrue that reason is.

    I didn’t read the whole book of course, but there’s tons of exec summaries and short talks on it that can help to understand it.


  • Do I honestly have to tell you that many nasty things can indeed pop up from beneath the waves? That nuclear-powered submarines can travel vast distances without surfacing?

    Ireland is nr. 3 in the EU in raw GDP per capita, bested only by Switzerland and Luxembourg. Yes there’s a lot of letterbox firms, it’s a tax haven, but even if you’d have to halve their number to correct for that, they’re still just as rich as the UK and France.

    How has the invasion of Ukraine not woken you up yet? Do you live on a different continent?
