I spent a couple months memorizing the test questions/answers with Anki, without learning the theory, and passed the second level test (the one below Extra, I forget the name). I got a cheap Chinese (ABBREE brand I think) radio but never learned how to use it, and am a bit worried about accidentally transmitting if I poke around on it, even if it is probably legal for me to do so (assuming I announce my callsign periodically and such). I'd been meaning to learn things properly once the test was out of the way but I kinda lost interest, I guess. I'll still renew my license if it's about to expire anyway. Might as well. Callsign not shared because I tied it to my real address and haven't gotten a P.O. box (also as previously stated I am not actually active).
If you are interested, find and go to an amateur radio club meeting. The licensing test makes sure you know the regulations and some theory. It does not help introduce you to "ham culture" which is definitely a thing. I learned all the practical stuff from talking with local club members. They are usually overjoyed for new members; if not just go to the next club. Youtube and whatnot helps but it's better to be able to ask someone a stupid question, and believe me, if you want to be overwhelmed with information, ask a ham a question. In my experience there are some assholes but more genuinely kind people, mostly older folks who just want to connect with someone.
Fullscreening windows is typically a feature of tiling WMs, and tiling often makes it easier to adjust the ratios of the splits in small amounts. I think tiling works well at all resolutions.
They are actually very nice screwdrivers. I had a cheaper no-name set before and ended up stripping screws a lot more often. I got their Mako kit and it's worked great the last 4 years or so. If you ever do work on old game consoles I would especially recommend it. Has the bits for the consoles and the games. Game Bit for GameCube, SNES, GB(C) games, Y bit for GBA and GBA games, security Torx for Xbox 360. The only times it falls short are for very recessed screws like on a Rock Band drum kit, you need a long dedicated driver to fit in there, I think anything with a socket tends to be too thick.
Sadly the T440p (my main machine for several years) and T420 run insanely hot even with fresh paste and a cleaned fan, at least while docked and in continuous use. Could not for the life of me overcome it. Got a T14 Gen 5 and it's a solid 40 degrees cooler now on average. Big relief. I'm guessing T480 is decently cool but haven't daily driven one to be sure.
Specifically the T14 had half or fully soldered RAM for the first several gens. Gen 5 restored the socketed RAM. T440p was the last with a socketed CPU. We've lost a lot of power user features over the years, but ThinkPads still tend to be better than most modern alternatives.
Lenovo has long had a separate board for the power connector you could separately replace. This is likely a continuation of that idea. I had an X220 Tablet (Released in 2011) from eBay that was sparking when I plugged it in. IIRC I just unscrewed and rescrewed the charging board and then it worked again. I guess there was some short, maybe it was loose. It would've been easy to replace just that part if it had failed completely.
Failing RAM is rarer than it seems from posts online. My theory is that it's so easy to test for that everyone says to do it even if it's unlikely to be your problem. It reminds me of people who needlessly recap (replace capacitors) everything in hopes of it fixing a problem, often not even bothering to test each cap or exhausting other options first. IME dirt/corrosion/oxidation (often solved by cleaning) is a much more prevalent problem than bad caps. After that, solder that needs reflowing is still a more common issue than bad caps.
That being said, I really did have one bad stick of RAM once in my life, and it really does cause strange seemingly random problems.
pmOS runs well on a couple OnePlus phones (6, 6T). For whatever reason the Snapdragon 845 and 865 have decent mainline support. I expect the OnePlus 8T to join the prior list of phones in the near future. You can similarly look at which gaming handhelds are supported by ROCKNIX and what SoC they use to get an idea for which ARM SoCs have decent mainline support. I expect the vast majority of phones and other ARM devices to not be very well-supported. RockChip is usually the safest bet, but I've been pleasantly surprised with some Snapdragon stuff.
I'm personally happy with LineageOS on OnePlus stuff, but have you considered getting a Pixel that's 2 gens or so old from eBay? I find old flagships drop in price pretty quick and are often a better deal than a new low-end phone.
