  • I tried Fedora KDE spin first but it didn’t work out for me. IDK if it was my hardware configuration it didn’t like but the first time I booted it, it spammed me with crash reports. I poked around it for a few minutes, not being able to go far without things crashing again and again. I installed the updates and rebooted it hoping it would fix it but it got much worse after that. I couldn’t do anything else as it immediately crashed at startup. I couldn’t be bothered to look any further into it and switched to OpenSUSE which has been rock solid for months and still going. I’m running Plasma 6.1 with Wayland on it with no issues as well and I know Plasma 6.2 is coming soon. It uses pipewire as default as well. To be honest, IDK what Fedora would do better for my uses, except maybe for a faster package manager.

    I’m certain that my Fedora experience isn’t typical but for me at least it was a disaster.

    As sound travels through a water layer where the speed through which it travels varies with depth, the sound will tend to refract towards where it is the slowest.

    A layer where temperature decreases as depth increases will refract sound downwards. A layer that has the inverse temperature properties will do the opposite. A layer that is isothermal (where the temperature remains constant as depth changes), will still tend to refract sound upwards because the increase in pressure also increases velocity, although not as strongly as temperature does, which is why temperature differences can easily overcome this effect where the water is not isothermal.

    If you have a layer that refracts sound downwards on top of a layer that refracts sound upwards, you just created a sound channel, which acts as a wave guide in which sound will remain trapped and travel far longer distances horizontally before dissipating.

    Ultimately you can’t really put a number on the required temperature differences because there are many other factors to take into account like how steeply the speed of sound changes, how tall the layer(s) are, what is the frequency of the sound, or how much of it you want to remain “trapped” in the sound channel.







  • I didn’t wait. I did it earlier this year and haven’t booted from my Windows 10 drive since then. My entry drug was Linux Mint. But I quickly switched to OpenSUSE Tumbleweed after because I wanted something that ran the KDE Plasma 6 desktop environment (I prefer how it looks and handles multiple displays). It isn’t that hard to learn the basics you need to use Linux, as long as you use a decently stable distro that you won’t need to troubleshoot at every update. In my limited experience, you only need more in depth knowledge when you try messing around with more “cutting edge” and less “stable” distros and are installing experimental features.

    I can’t believe that Microsoft is expecting everyone to get rid of their computer to switch to 11 once the support for 10 expires next year. I even revived an 15 year old laptop that only had 4Gb or RAM by installing Mint on it (and switching its HDD with an SSD I had kicking around). It’s fast and perfectly usable for everything but modern games now










  • I did it soon after switching to Linux Mint from Windows because I didn’t like how Cinnamon was handling multiple displays. It worked and was perfectly functional. But it was a little rough around the edges with the occasional glitch here and there. Not sure if it was because Mint wasn’t really meant to run Plasma or if it was just because it was running an older version of Plasma. But it was perfectly usable and I would have been happy to stick with it if there were no other solutions.

    Before I got too comfy in my Mint install and after having familiarized myself with Linux better, I hopped between a few distros for a bit. LMDE6 with Plasma ran better but ultimately I switched to OpenSUSE Tumbleweed and stuck with it since then. It is rock solid and runs Plasma 6. I should probably have given EndeavourOS a try as well but I’m now too settled and comfy to change.

    Mind you, I am still a complete Linux noob and still have barely any idea of what I am doing so take it with a grain of salt.
