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).

You can have a closed loop that exchanges heat with an open loop. This PR video doesn't explicitly say that, but shows the evaporation setup: https://youtu.be/th6jVeaMyxo?t=90 (it also mentions using sea as a heatsink when available).
Do checks aid surveillance less than other non-cash payment systems? I would expect that a check specifies the payer and the payee, is seen in full by at least the payee's bank, and is probably stored for nontrivial amount of time by that bank.
Do elevators still have emergency stop buttons? I don't remember seeing one in the last 10+ years.
Re location of the button on cars: I would guess that fire alarm pull stations/button stations have had lots of thought put into making them easy to use and discouraging prank use. I would guess that lots of that would translate.
I'm also curious whether throwing a tarp over some part of the sensors would actually be effective today.
@mcc I am not up to date with FIDO2, but I suspect that the spec allows services that accept passkeys to decide whether to care about passkey's provenance. I don't know how many do care. For U2F (the previous standard) caring about provenance was IIRC very rare.
@eventphone Werden die Kurztextnachrichten über DECT während 39c3 funktionieren? (Mitel's Doku scheint zu sagen, dass das selbstverständlich innerhalb ein OMM ist, aber ich kenne mich mit DECT-Infrastruktur nicht gut aus.)
@_thegeoff If you haven't read Buzz Aldrin's PhD thesis, I recommend it.
@lcamtuf you might already know about switched capacitor amplifiers; in case you don't they use a similar principle around an opamp to yield improvements in behavior under finite open-loop gain or in precision, very similar to the ones you're showing.
@kuba Ludzie tego tak używają? Dla mnie to znaczy coś innego (zakładający, że heteroseksualność jest normą).
@mwk Do I get it right that PCF8574 will pull the pin down whenever you ask it to read and it reads a 0? (I'm basing this off fig 7-2 in https://www.ti.com/lit/ds/symlink/pcf8574.pdf)
Ah, sorry, s/conditional with assume_unreachable inside/conditional with (un)likely around the condition with empty body/
You can make up a conditional to do so: https://stackoverflow.com/a/26195434
It's always unclear whether the optimizer will be able to make use of that, but I'm pretty sure that (as long as the conditional expression is obviously side-effect-free) the optimizer will remove the conditional if its body is just assume_unreachable.
I know that Gemeinschaftszentrum Buchegg organizes a repair cafe and claims to handle electronics, but I don't have first hand experience with them.
Now that I looked at their website (https://gz-zh.ch/gz-buchegg/angebote/repair-cafe/) I noticed that https://repair-cafe.ch/ is a thing.
Isn't that hard to distinguish from transmisia?
Which part of packaging do you mean? Brotli describes bit order and how to deal with intra-byte boundaries between Huffman-encoded and constant-bitwidth stuff. I'm probably missing something, because that seems to me to be sufficient?
Disclaimer: I was somewhat involved in both.
@dpiponi Do you expect that some summary of accelerometer readings could tell a bit of a story? (I would expect that it could identify the type of conveyance used to transport the airtag and, in some cases, narrow down to a small subset of vehicles: it could detect precise timing of aircraft takeoffs and maybe landings and of the times when a train stopped.)
@mcc There's a pinning difference, and I wonder if that's the only one.
@_thegeoff There's a mod that makes orbital dynamics consider bodies other than the closest one btw. (I haven't played with it yet, but a coworker seems to have high opinions about it.)
Another thing to think about is how much your motivation depends on presence and properties of company (does it help significantly if you have people trying to learn the same thing, or maybe people who will be at least somewhat interested in what you're trying to figure out and will ask nontrivial questions?).
