  • I have some steelseries (I believe maybe arctis 7 or 9? I should check, not the one that also does Bluetooth), and it works fine after using the accompanying software once years ago to set mic loopback to the level I like.

    It has

    • mic loopback (adjustable with the windows only software but set and forget)
    • 2 channels, one for chat and one for “gaming” i.e. anything else. Perfect to set gaming as default output and slack or teams or discord or whatever you use to voice chat to the chat channel and you can use the knob to dial between 0% chat & 100% game <-> 100% both <-> 0% game & 100% chat
    • another knob for the global volume which then combined with the other knob allows all possible configurations
    • mic mute button
    • usb micro-b charging
    • some weird specific cable that does 3.5mm jack iirc, never used it but then you can use it for your phone I guess
    • connects to your computer using wireless (2.4ghz usb dongle at computer side)

    All of those in hardware so no software needed, except for the mic loopback, so pretty happy with that. I’ve had it since my windows 7 days, and I refused to “upgrade” to a higher version of windows, instead upgraded to linux, so it’s been going strong for years and years now

    Only thing was that I replaced the over ear pads

    9/10, easily













  • I assume only German citizens can sign this? I upvoted here if that helps, because it sounds like a great initiative, maybe if this gains traction this can go europe wide?

    The difficult part is measuring work done I’m afraid though. For volunteer work as e.g. reading books to kids or cleaning streets it’s relatively easy to see that things are happening, even if some are better/faster than others. Unless you’re going to force people to work in live calls or whatever, or just trust self-reporting, that’s going to be hard, no?

    Or do you mean more like subsidies for nonprofits working in open source?

    Either way, good initiative, I hope for its success!




  • For me the biggest leap was letting go of my local settings. My kubuntu has about everything I want out of the box, then I install zsh with omz and I’m pretty much done.

    So whenever I break something it’s an easy fresh install.

    My data (steam games, code) is in a separate drive, and especially with cloud saves / git everything is available even if I were to break that drive (would just suck to remember which things I need to redownload from where).

    So that helped me release my tinkering spirit as much as I wanted, and while I’m far from a Linux guru, I’ve definitely learned a lot from that.

    Edit: not to say that I don’t try to fix things, just knowing that I can easily restart is the main thing.




  • Close, but now you come into contact with the atmosphere not actually being the same density (in weight/volume as well as in particles/volume) throughout, but instead gets thinner as you get away from the earth.

    For simplicity, assume space is actually empty, and the atmosphere gets thinner linearly up until x kilometers above sea level it’s completely empty. Then the density will also decrease with height, and the helium balloon will eventually find a spot that matches its density, and stop there.

    Again there’s so much more to it but as a simplified model this works 😅

    Rockets mostly need to fight speed (of the earth revolving around the sun), and indeed in our atmosphere speed means friction, but in space rockets still need a lot of propellant to change their trajectory. As always there’s a relevant xkcd: https://what-if.xkcd.com/58/


  • The very short answer is that gas pressure is mostly proportional to the amount of particles per volume.

    So a balloon filled with helium has X particles per cubic cm, while the air around it has the same amount (instead of getting crushed). But because helium is a lot lighter per particle than standard air, this makes the balloon lighter than air, and like trying to push an air-filled balloon underwater, this helium-filled balloon floats to the higher layers of air, until other smaller forces also start to matter and the balance is restored.

    So a “vacuum-filled” balloon has nothing to give counter-pressure, but a balloon filled with helium definitely does.
