  • You misunderstand, the first two commands are just one time setup to install a specific python version and then to create an env using that version. After that all you need is `pyenv activate myenv´ to drop you into that env, which will use the correct python version and make sure everything is isolated from other environments you might have.

    You can also just create an env with the system python version, but the question was specifically about managing multiple versions of python side by side and this makes that super easy.

    You could also combine it with direnv to automatically drop you into the correct environment based on the folder you are in, so you don’t have to type anything after the initial setup.






  • I always thought the Mer de Glace at the Mont Blanc illustrates this really well. You arrive and there’s a sign “the glacier was here in 1910” and that’s where tourists back then.

    To get to the actual glacier, you have to eall down many flights of metal stairs for about half an hour and there’s several signs for different years, 1950, 1990, 2002, 2006, 2009, 2012, 2014, 2015, something like this, with the years between each sign getting shorter but the distance staying roughly the same. And from the top it’s really far away.

    Of course, once you actually reach the glacier, you get to the main attraction, a 3m diameter tunnel they bored 100m deep into it as a tourist attraction with ice sculptures inside. Above the tunnel you can see the remains of the tunnel from the previous year, half melted…






  • Just to add to this, because it’s fascinating. GPS satellites signals are about as strong as radiation from a light bulb, 20000km away. The signal that arrives on earth is 20db weaker than the noise floor, so background noise is a lot stronger than the signal is.

    The way it works is that the background noise is random and the signal is repeated many times a second, so you can split the signal and add it together. The random background noise averages out and you’re left with a strong signal. But due to this, it’s enough to have a very weak signal that adds non random noise on the correct frequency for it to just break.

    And actually what I desribed above is just the first layer of a GPS signal, it gets a lot more complicated with signals within signals, it’s pretty crazy how well it works. this is an amazing write uo on how the signal actually works, in case anyone is interested



  • Those are not the same things… Glass is better for the environment, for one it doesn’t break down into microplastics which get everywhere. And glass can be recycled indefinitely (minus some loss due to impurities) whereas plastic can be recycled up 0-1 times usually.

    Plus the whole “it’s up to consumers to solve this” is just corporate propaganda to absolve themselves of any responsibility, all the while not offering any alternatives that a consumer could pick from. Like literally, they paid for marketing campaigns to convince the public that it was our fault.




  • there’s a lot of stuff you can do, and you can end up with something usable, though not great, at least not in my experience. NVidia’s drivers are to blame, they don’t really work well with opengl and have lots of issues (and also regressions).

    The 550 beta driver is ok-ish, steam flickers but I can play games. Drivers before 535 also somewhat worked, though it really depends on your GPU.

    But I don’t think you will have it working acceptably without some work.

    Here’s some pointers on stuff to try:

    • check protondb for how other people got games to work, you can filter by your GPU.
    • try running through gamescope or gamemoderun
    • try the modeset=1 (and maybe fbdev) kernel parameters for nvidia drm
    • and there’s tons of env vars and other things that can help, I couldn’t summarize them all here, but as a pointer: XWAYLAND_NO_GLAMOR=1, WLR_RENDERER=vulkan, LIBVA_DRIVER_NAME=nvidia, GBM_BACKEND=nvidia-drm (for the drm above), __GLX_VENDOR_LIBRARY_NAME=nvidia
    • try the beta drivers, if those are available somehow (I’m on arch so they were easy to install), or just different driver versions in general.

    The above is meant more as hints than something to copy paste, so use at your own risk. You can of course always just install a second DE with X11 and log into that for gaming and use your regular DE for everything else




  • Oh don’t get wrong, it works fine for comics. the small screen and having to move around whole pages, and sometimes struggling to read small writing are issues (you can zoom but it’s not very responsive) aren’t great, but I’ve read many a comic. But if comics are the main use case, I’d probably go for a tablet still. If you get one for books solely, then the color one has less DPI and more ghosting, that’s why I wouldn’t recommend it.

    And I don’t use the color feature much outside of reading comics. I thought it might be nice for color diagrams for work, but it’s a bit hard telling the colors apart when it’s just thin lines.

    But I’m super stoked for where the color e-ink technology is heading.

    I mostly used the stock boox neo reader for comics and didn’t have an issue with ram. Do you know how it compares to Tachiyomi?
