  • Well, the closer you are to the North Pole, the easier time you will have crossing time zones, distance-wise.

    Since I’m doing the math on my phone, I’m using an approximation of the Earth being a sphere with a radius of 6371km, and your train track is directly west, all at the same latitude, and equal longitude based timezones every 15°.

    The circle around our Earth at that latitude has a circumference of 2 × pi × 6371 × cos(theta), kilometres, where theta is the latitude (imagine a triangle between the starting location, the centre of our model Earth and a point partway along a line that connects the equator and the centre). Divide that by 24, and that is the distance you need to travel in my model scenario to go back an hour, and thus the speed in km/h the westbound train needs to go to repeat the same hour again consistently.

    Examples:

    • Going directly west from Vladivostok: 1667.92 × cos (43.12°) = 1217 km/h
    • Going to St. Petersburg: 1667.92 × cos(59.94°) = 835 km/h
    • Going from the tip of the mainland of the Russian Far East: 1667.92 × cos(66.06°) = 677km/h
    • To Murmansk: 1667.92 × cos(68.98) = 598 km/h
    • From Saskylaky, a rural settlement: 1667.92 × cos(71.96°) = 516 km/h
    • From the uninhabited top of the Russian mainland through a railway on the ocean: 1667.92 × cos(77.74°) = 354 km/h
    • From Rudolf Island, northernmost island in Russia: 1667.92 × cos(81.76°) = 239 km/h
  • Welcome to Lemmy, thanks for the post detailing your experience and glad to hear you’re getting your family onboard too! I think you’ll feel right at home with the Linux nerds and tech privacy wonks here.

    I wanted to consume the content instead of just being fed it.

    Like you, this is the basis of a lot of my motivation to try and then stick with these FOSS programs, but perhaps differently than you, it also guides the extent to which I feel comfortable continuing to use some proprietary software and algorithms. I’ve committed to interacting with technology on my terms, even if I have reduced but not fully cut myself off from big tech.

  • I don’t think you’re alone. I’m serious and occasionally judgemental on Lemmy, and if I am discussing something I care deeply to ensure the accuracy of my facts whenever I make a claim.

    In contrast, on meme and shitpost communities, I’m a lot less serious and more of a jokester. My suggestion is it might be best for you to avoid the politics communities. Make some posts sharing your pics, arts and crafts, there is much less judgement (and for people that think it’s their job to judge your craft beyond helpful and constructive criticism, you should block).

    Oh, also if you see a comment that is nested more than 6 times down, and it’s not the AskOuija community, it’s probably best to skip over reading all that, becuase it’s often two annoying users going at each other. They might be having fun, but there’s no need to get yourself involved.

  • What’s the threshold for a tag?

    Just add context as a top level comment or in the body text area. Someone can come in to clarify if the poster is missing it.

    Even for a poster sometimes it’s not obvious if there is any AI in the project. Example: Lutris, dev said they are adding Claude commits and will be scrubbing mentions of the tool from PRs. Sometimes AI is discussed but rejected.

    It’s easy to tell when a whole project has been vibecoded, but the grey zone of an existing project that may or may not have had slopcode added, is tougher for posters to discern.

  • The function I used most often aside from the usual sequence is Alt-SysRq-F. This runs oomkiller to SIGKILL what would appear to be the process hogging the most memory. That was usually enough to get control back from an agonizingly sluggish system caused by hitting the swapspace. I didn’t need it anymore after I upgraded to 48GB of RAM.

    Another way to remember the classic mnemonic, it’s “busier” in reverse, after holding down for a second the Alt and SysRq keys (which may require a function key combo on some keyboards).

    You should check ahead of time whether the value of /proc/sys/kernel/sysrq is not zero to be sure the Sysrq functions are enabled. If not, then in /etc/sysctl.d/99-sysctl.conf you can add the line kernel.sysrq = 1 to enable all features, or a higher number to enable select features.

  • In current day tech, East Asian characters are taken from a combined set called “CJK unified ideographs”. When regional variants exist, the language it renders as depends on the font of the user’s device.

    There was a recent example that came up: 骨(bone) has the little square on the left in Simplified Chinese and on the right in Japanese. With Hiragana it’s more obvious because of all the curvier letters, but with kanji only phrases even smartphones tend to mix it up.

    I can’t tell between Hungarian, Romanian, Bosnian, Albanian, Czech or Slovak, because I haven’t really studied any of them or know any words. In the Cyrillic field, Belarusian, Russian, Ukranian (except for the existence of ï), Bulgarian, Serbian I probably couldn’t be able to tell you what faced with a random paragraph of text.
