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).

Ending up with screen-inside-screen and having to figure out how to detach the inner one.
Having a program leave the terminal in some weird state when killed (either without echo, or in that weird alternate charset mode that can be fixed by _outputting_ ^O).
Not having job control at all (i.e. can't kill or suspend anything that I start in foreground) in some kinds of emergency shells (probably due to something like http://lists.busybox.net/pipermail/busybox/2002-June/006397.html).
Problems with terminals that are misconfigured so that control sequences are misinterpreted (most recently I had the issue when sshing to something that didn't understand `TERM=rxvt-unicode`).
Heh. This reminded me of the annoyance with the Polish signaler simulator (www.isdr.pl), where you can't really reroute a train. The only way to get it to do something other than in its schedule is IIRC to use shunting instructions to start the deviation.
Where would you put the line that distinguishes this kind of work and work of e.g. a water pump (which I assume you don't object to on similar grounds)? On "can be commanded using nontrivial expressions of natural language" maybe?
TBF Factorio's signaling automation encompasses both signaling and decision making that's normally done by the signaler and/or dispatcher.
Actually, @gregeganSF in case he finds this topic interesting. tl;dr how could a world look like if "legal positions" were quantized to a grid at a scale that's macroscopic (or nearly macroscopic) to its inhabitants.
Hm~ I then don't understand what level of self-consistency you want (nit: it's not a biological detail, because anything that processes information will have such problems). Another thing to think of in such a world is the question of straight lines: are all directions permissible in contexts where something spreads along a line? What's the distance in e.g. electrostatic attraction, or what are the directions a light ray can travel in (I vaguely remember that restricted wave propagation directions is something we do encounter in our world in some crystal structures btw.)?
If you haven't already seen anything by Greg Egan, you might enjoy his novels and stories. Many of them posit worlds with different physics (and two even with, after a fashion, different mathematics) or different ~biology (with the source of the difference unspecified) and try to extrapolate into them. Depending on what is the difference in a given story, the extrapolation is either very detailed (e.g. Clockwork Rocket), very vague (e.g. Teranesia), or somewhere inbetween (e.g. Morphotropic).
> instead you'd have a discontinuous "this length of fence can enclose this much area" table without any clear ability to infer intermediate values.
But we do live in such a world too! A fence in our world has some number of molecules in its circumference, their connections can just stretch somewhat (and usually there's a mixture of connections of very different lengths, and the fence is nonnegligibly wide, etc.). The only reason we don't think in those terms is that our fences are much larger than that ~quantum.
If you posit that the quantum is macroscopic in the proposed world from the POV of some intelligent entities, then I doubt whether they would have enough volume to store enough information in their minds, unless you posit some very-high-information-content indivisible (i.e. of the size of one fundamental cube) thing.
@munin Why not? You can still go to the limit of large sizes. Similarly in our universe we are nearly always considering setups where the Planck length (or even diameter of a molecule) is infinitesimally small.
@munin By coming up with largest surface area you can encircle with a fence of some length?
I'm not sure how rotating things would work in that world though (if you can rotate things, length of a fence is a thing you can talk about, because you can unwrap it and measure).
Do you have some more reference points (i.e. printers that you had a significantly lower success rate with)?
The general principle I've heard many times is that one should not care about noise alone. (That said, noise can help in diagnosis of other problems -- many issues have specific angles of flexion at which noise/crepitus might occur.)
Also, there is at least one completely benign reason for joint noise (I'm not sure how common it is in knees): cavitation creating and collapsing bubbles. This is why you can crack your knuckles.
Without any lathed parts, or also without parts that were made with lathed tools etc.?
@munin How much do you want to cover by the notion of the same tool? For example, golang compilers usually get built with earlier major versions thereof (and eventually with a C compiler) -- would they count?
and starts to arrange for such accidents, because they tend to happen too rarely for their liking.
For that reason also running `foo` and `cat | foo` will exhibit different effective stdin buffering behaviour -- in the former case `foo` will see your input line-by-line while in the latter likely will see it only once you send EOF (the buffer is iirc 16KiB).
