    Hydrogen, even with fuel cell/electric, is not suitable for rural car owners. It’s only really suitable for vehicles that are constantly running, like freight trucks. Why? Because hydrogen leaks out of any vessel you try to put it in. It’s the smallest element in the universe so it slips past the molecules of whatever sealing material you are using. It will even permeate through solid metal, making said metal brittle in the process. And this problem of course gets worse at higher pressures, which you have to use to get any energy density.

    So not only do you have to contend with the terrible efficiency loss of using electricity to create hydrogen only to turn it back into electricity again, a whole bunch of your fuel is constantly leaking out during transport and storage. And then if you use cryogenic hydrogen for the best energy density it gets worse again because you can’t keep it cold enough. It’s constantly boiling off and has to be vented to prevent your tank from exploding.

    So even if you solve all the myriad other implementation problems with hydrogen, you’re never escaping the fact that you need to use all your fuel quickly or you’re setting money on fire as it leaks. Not to mention potentially getting stuck because you didn’t drive your car for a few days and now you don’t have the fuel to reach a fill station.

    Hence why, if it ever matures enough to become actually viable, it will almost certainly be limited to freight and courier type vehicles. They run near constantly and so burn through fuel fast enough that the leakage isn’t an issue.




  • Because the industrial base for producing critical things like ammunition is nearly nonexistent. Despite USA and European arms support Ukraine has been permanently shell-starved for the entire course of the war. Three years later, even after spinning up some new production, Ukraine’s allies still don’t make enough shells to get anywhere close to 1:1 with what the Russians fire at them (and that was before North Korea started supplying the Russians)

    The invasion of Ukraine has made it crystal clear that Europe’s military industrial base is utterly incapable of responding to an actual peer conflict on their own soil, let alone providing a deterrent to wars of expansion outside of it. It would be foolish not to be investing in sovereign military capability in today’s world.

    It might not be the 😵 kind of poison but it is absolutely the 🤮 kind of poison, even when decarbed. I’d describe it as 🤢🤢🤢🤮🤮😵‍💫🤮😵‍💫🤮😵‍💫🤮😵‍💫😴😴😴 and definitely not 🤤 at any point.



  • I’ve had two different arch based distros have issues when trying to update after long periods. I also had an Ubuntu server fail completely when doing a major version upgrade and had to restore it from backup. But then again I’ve also had no trouble updating an Ubuntu machine that was a couple years behind.

    I’m on Fedora now for my desktop and it’s been great so far, but I also do updates at least weekly. My advice would be if you expect to go months between updates your best choice is probably Debian.



  • I’ve only been fully on Linux for about 4-5 months, but am yet to experience any issues on Fedora KDE with Wayland. Previously while I was distrohopping I was having a bit of a rough time but since settling on Fedora and with Plasma 6 it has been smooth sailing.

    I’m using an AMD 5700X/B550m and RX 6700 XT. Also with two mismatched 1440p displays (different refresh rates).


  • I agree but I do have a little issue with the “wasting resources” part, that’s a very anthropocentric view to take. There’s an entire ecosystem of organisms that would love to use those resources, and in many cases leaving the carcass behind is better for that system than taking it away and depleting it of that biomass. There’s obviously a lot of “ifs” involved but I wouldn’t generalise by saying that because a human didn’t get to eat it the resource was “wasted”.

    It’s unfortunate that our ancestors have left us with this kind of ecological trolley problem, where in order to keep the system balanced and prevent collapse we’re obligated to go out and kill a lot of creatures, but such is the world we’ve inherited.

    This isn’t the first time such a vulnerability has been found, have you forgotten spectre/meltdown? Though this is arguably not nearly as impactful as those because it requires physical access to the machine.

    Your fervour in trying to paint this as an equivalent problem to Intel’s 13th and 14th gen defects, and implication that everyone else are being fanboys, is just telling on yourself mate. Normal people don’t go to bat like that for massive corpos, only Kool aid drinkers.

    Fun fact about mushroom toxicity by contrast. Because the mushroom is only the reproductive organ of the organism, and you’re basically doing it a favour by picking it and spreading its spores everywhere, theres no evolutionary pressure for it to evolve toxicity to humans. So the compounds in mushrooms that are toxic to us likely exist for other purposes, and are only toxic to us by coincidence.

    For this reason the proportion of species of mushrooms that are safe vs. the number that are toxic is greater than with plants. Because plants have had selective pressure to evolve poisons that discourage or prevent herbivory. So if you walk into an unfamiliar forest and pick one plant and one mushroom to eat at random, it’s more likely the plant is the bigger danger.

    Of course I absolutely do not condone eating plants or fungi at random unless you intend to have a painful death.
