  • Because you say mechanical that does might preclude chemical reactions…

    At least a basic level of a real world self-replicating “device” in an abstract sense, you can “grow” some crystals given sufficient substrate liquid.

    I think it is theoretically possible, and may be easier to realize at a microscopic scale since you can get a sufficient amount of liquid that can be considered a ‘functionally-infinite’ space and the device can more freely float around without having to worry about needing complex dextrous parts to put things in the right place.

    A loose ball of dandelion seeds I put together would be my idea of a simple self-replicating ‘device’ that operates mechanically, in the natural world, at a human scale that I think meets your criteria. It floats around in the area and if there are dandelion fields where it goes, it can pick up the seeds, and if it bumps into a random obstacle in the landscape it will break into parts that can pick up other seeds. The only logical aspect of the device is how many seeds it is comprised of, and there is not a set sequence as to when it will break, because it just depends on where the wind pushes the ‘device’ into in the landscape.

    Addendum: Condition 4 is hard to get around with my example, I can’t guarantee that when it breaks apart only dandelions that weren’t part of the original part would formulate the new part. Seems overly perscriptive if you count using its own constituent part to make a new part, then repairing itself up again as contravening that condition.






  • I like that there are a variety of apps and services for different tastes and needs. On services, I like that Pixelfed and Loops exist to fill Instagram style niches for people even if it’s not my cup of tea. Jerboa is a no-frills Lemmy app and that’s how I want it, but I appreciate that there are many others with a plethora of features and styling choices that suit people, and are not forced to a single kind of experience.




  • 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.





  • 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.
