  • 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.



  • My grandfather did the exact same thing. But he was in conquered France and did it to avoid being drafted by the Nazis.

    Edit: There were also a stories of other people in the village finding other ways to avoid the Nazi draft. One of them pretended to be deaf and managed to avoid falling for a few tricks the Germans played on him in an attempt to expose him, such as dropping a coin behind his back. Another one reported to the draft medical examination after purposefully biking over an insanely long distance. When he arrived he was completely exhausted and the doctor deemed him too anemic for military service. All of those in the village who couldn’t dodge the draft were sent as cannon fodder on the eastern front and never returned, except for one “lucky” individual who lost a leg.









  • 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’ve spent over a decade in the army where you’re taught to pride yourself into “embracing the suck” and the whole “pain is all in your head” mentality. I have now taken a different career path and realized that this kind of mentality is only useful in very specific cases and is otherwise very bad. But to this day I still tend to downplay and hide my problems/pain whenever things are wrong.

    That nearly got me killed a year ago when I showed up at the ER with pulmonary embolism (likely caused by a COVID infection) and the doctor dismissed it because I didn’t look in pain enough for it to be that. The doctor sent me home untreated. It would have likely killed me had I not returned the day after to see another doctor who luckily took me seriously and got me a CT scan that revealed the problem.
