  • Alright. I’m a huge supporter of Ukraine here. But the west has been collectively providing Ukraine with a metric fucktonne of weapons. Russia is clearly the aggressor, at fault, and fucking evil. But if we can send weapons to Ukraine, Russia acquiring weapons elsewhere is probably fair game. That doesn’t mean we can’t apply economic or political pressure.

    In many ways, this war dragging on for a long time is actually in Chinese interests, as far as I can tell. It makes the west war-weary making it less likely we can sustain another conflict should China decide to engage over Taiwan or similar. And it increases Russian reliance on China in the longer term. The only thing China is likely unhappy about here is NK’s increasingly large role (moving into Russian sphere of influence).

    But unless we’re willing to actually sanction China, the west will just complain and do nothing.


  • The list is great! But it doesn’t really tell us which ones are actively developed. Running historical DEs is fun sometimes. For example, LXDE doesn’t really see a lot of development compared to its successor, LXQt. But once again shows the the Arch Wiki is the best ;)

    I guess people do occasionally compile KDE 1.x just to see if it still runs on modern systems (it does, but obviously some underlying things have changed over the years, like the audio and graphics stacks). But that isn’t the same as being actively developed :)

    This depends on what you’re optimizing for. If you are optimizing for total energy captured per square metre, then you’re right about the benches.

    But suppose you have a sufficient flux even with some areas being covered so you aren’t bothered by the shadows. Wouldn’t it be aesthetically superior to have uniform tile types? Or would you prefer they micromanage the tile placement such that the tiles below the bench shadows are different?

    Anyway, I think it is a good idea. Better than the silly solar roadways crap.


  • Someone enlighten me. How many active desktop projects are there currently? (Not just window managers…)

    KDE Plasma, Trinity (is it active? Fork of KDE 3.5)

    Gnome, Mate, Cinnamon (fork all the things!), or “reskins” like Unity or Budgie?

    LXQt, Xfce… Is enlightenment still active as a project?

    Does anyone use Deepin – appears to be a partial fork of KDE (kwin, etc.) with new desktop environment built around it rather than use Plasma.

    Or Pantheon (Vala+GTK3?).

    Cosmic is from the ground up, recent and active I guess.

    Missing anything?


  • When you believe in an all powerful space fairy, it’s quite easy to believe in other arbitrary nonsense too. QAnon was an interesting phenomenon, as it was uniting the crystal woo hippy left antivax crowd into the magical space fairy religious right. And the radicalization pipeline took it from there.

    It’s not necessarily religion that is the problem here. It’s that people who don’t have critical reasoning skills are drawn to religion. But they’re also drawn to whatever other bullshit anyone is peddling.

    Excuse me a moment, I need to adjust my magnetic bracelet and turn on my Himalayan salt lamp.





  • Did you take physics in high school (or elsewhere) and learn about half lives? Many of the main ingredients in nuclear weapons all have half lives: tritium, plutonium, etc – and most have fairly short half lives. They need to be continuously produced, enriched, refined, etc. to keep the purity high enough to be detonated. Some of them require breeder reactors and other fun thing.

    Well, okay, U235 has a half-life of 700 million years, but you still need to enrich uranium to increase to proportions of U235, since U238 cannot sustain a chain reaction.

    The original nuclear weapons were U235 weapons. Later bombs added all the harder to make stuff to make them bigger – fusion bombs still usually have a U235 starter to get the reaction going, but rely on things like tritium and plutonium to do the fusion bits. Even the Lithium-6 (which is stable) slowly decays to helium and tritium inside the weapon as neutrons from the other components hit it.

    Anyway, enjoy the Wikipedia rabbit hole.


  • The good news about nukes: they have a shelf life – most soviet-era nukes needed to be replaced every 12 years, as the loss of fissile material to natural radioactive decay would render them dirty bombs after a certain point. Now don’t get me wrong, a dirty bomb still sucks, but it’s no nuke.

    So when a collapsing Russia is hypothetically selling nukes, they’re probably selling old depleted nukes or nearly expired nukes. To a terrorist it is almost the same thing, but to nation stations looking at MAD, it really isn’t.


  • Not in favour of the individual suffering here, but illegal mining is about the worst thing that can happen anywhere.

    Furthermore, in most jurisdictions where illegal mining happens, you get these gang run pyramid scheme shenanigans going on where the miners are very nearly enslaved to their handlers. Shutting them down can only be a good thing!

    On the larger scale: Environment and safety regulations exist for a reason.

    That said, the suckers in the mine starving themselves to avoid arrest might not see it that way.
