I enjoy things around information theory (and data compression), complexity theory (and cryptography), read hard scifi, currently work on weird ML (we'll see how it goes), am somewhat literal minded and have approximate knowledge of random things. I like when statements have truth values, and when things can be described simply (which is not exactly the same as shortly) and yet have interesting properties.
I live in the largest city of Switzerland (and yet have cow and sheep pastures and a swimmable lake within a few hundred meters of my place :)). I speak Polish, English, German, and can understand simple Swiss German and French.
If in doubt, please err on the side of being direct with me. I very much appreciate when people tell me that I'm being inaccurate. I think that satisfying people's curiosity is the most important thing I could be doing (and usually enjoy doing it). I am normally terse in my writing and would appreciate requests to verbosify.
I appreciate it if my grammar or style is corrected (in any of the languages I use here).

I agree this is an example obviously on one side of that line. What I'm curious about is if any of y'all have a litmus test for which side of that line things close to the boundary are on.
Rzeczy które nie wymieniłeś, które wpływają:
- pilność potrzeby/chęci (skojarzona z tym, co szybciej wyjdzie),
- jak dużo lepiej/gorzej będzie działał obiekt przeze mnie zrobiony skojarzone z tym, jak bardzo jestem w stanie zrobić go w sposób bardziej dla mnie przystosowany,
- potencjalne towarzystwo w robieniu,
- jakich czynności wymaga robienie (niektóre są nieprzyjemne lub nudne-ale-wymagające-uwagi).
Ciekaw jestem, czy ludzie mają podobne odpowiedzi na temat generycznego obiektu i na temat jedzenia.
Where would you put the boundary between "this person is wrong on the Internet" and "this person is persisting in causing others to be misled in a harmful way"?
I'm confused why the article claims that the report focuses on emissions, rather than on problems along the lines of sailors using something that reports their location over the Internet to all sorts of garden variety data brokers.
Hm~ I'd expect the Navy to buy data from data brokers to see if anything shows up where their ships are underway. I wonder if I expect correctly.
@elithebearded
Hm.. it seems that doing that to a video of something rotating gives you a somewhat distorted view of that rotating thing?
I once saw a DIY car alarm that had no horn. Instead, if it triggered, it would display a "stolen. call police." message somewhere around the rear windscreen _only while the car was driving_.
The diffraction limit might imply that your sending antenna has to be impractically large (in diameter). Some Greg Egan's stories include a variation of that, where the thing that's accelerated is not a craft of any sort, but something that will in a few milliseconds from being launched (onboard time) start constructing the desired craft out of the material of the moon/star it has just impacted into. One example of a story of that shape: https://www.gregegan.net/INCANDESCENCE/00/Crocodile.html (I can't find the story that I remember having a closer approximation to what you described.)
@kravietz Does is really use a reverse-driven screw pump to generate energy? (I've never seen such an approach.)
@eoaiuastwg Example 2 (there's something weird going on with the font for the comments, but the code one seems monospace)
But what's the score?
How would you define that for things that you don't normally make at home? (I'd guess cheese/tofu could be one example.)
Do you have examples of solutions that are hardest to come up with using just the understanding how things work? I wonder if these are mostly things where Yet Another tool is helpful, where a tool has a somewhat hidden feature/option, or something else.
@b0rk BTW I think the parent post didn't federate to your instance (not sure why; length? happenstance? some problems caused by your question having been edited?) and I think no one else mentioned the /proc/N/root trap.
Absence of evidence is (usually weak) evidence of absence though. It's not the case only in situations where we're not looking for evidence in the empirical sense, but in a mathematical proof sense.
Some of these problems were actually useful for me, because they caused me to realise I misunderstand something (e.g. the behaviour of current directories that contain symlinks in their path, or how the commandline is parsed (see the "how do I remove a file with a name that start with a dash" problem), ...). For that to work, one needs to have resources to learn what's going on that can be used in the time one has available to spare (so it works way better for same resources for tinkering teenagers than someone just trying to use the system to get this particular thing done today).
Does putting them in the fridge significantly lengthen the time they remain edible? (I remember an onion expiring in a _different_ way when cooled and haven't actually experimented, so am unsure.)
PS. I hope/wish you have an uncomplicated (in any way) recovery.
"Fake" symlinks in /proc. For example, /proc/PID/root/some/path is not necessarily the same as $(readlink /proc/PID/root)/some/path (there might be no other valid path that points at /proc/PID/root, when you have mount namespaces and e.g. yours have that directory shadowed by a mount).
`mkdir -p` failing with `No such file or directory` due to a dangling symlink in the requested path.
Potential effects of `cd .`: filesystem gets asked to resolve the path again, because shell actually does sth like `chdir(getenv("PWD"))` in that case.
Related: when you move a directory that's above some process's working directory, that process's working directory moves, but if it keeps track of its working directory path (like shell does) that will become desynced.
Writing to a mountpoint before the filesystem gets mounted, ending up writing "behind" the mountpoint, and being very confused where the files ended up (in rootfs in the mount directory, but its contents is normally invisible when something is mounted on top).
Don't they sometimes mean "but it (or its future replacement) is not guaranteed to continue to have properties we'd rely on"?
Shell builtins vs identically-named commands in PATH.
