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.

@munin @ra6bit aluminium oxide is already potentially bad~~ (also, it would be a mixture of uranium and uranium oxides, which might actually be worse)

@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)

@sin

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.

@JessTheUnstill @baldur

Isn't that hard to distinguish from transmisia?

@ignaloidas @lynne

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.)

@avatastic @_thegeoff

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?).

@_thegeoff Fluid mechanics? How blood flow splits between vessels is somewhat nontrivial, and I'd expect that there are nice scaling rules to be had around determining whether blood flow in some area will be laminar.

Not physics per se, but maybe statistics in the area of measurements with inaccuracy? "How do we tell with few measurements whether this value increases over time" is something I haven't seen doctors and vets have an intuition around.

@0xabad1dea I agree that it seems to have been applied all the time the train was visible. I wonder how much earlier it got applied: only when the crossing got into view, or significantly earlier at some sort of pre-crossing signal (not a block signal, but a crossing status signal -- I'm not sure if Netherlands has those though; for comparison, the signal in Poland looks like this: https://www.transportszynowy.pl/Kolej/sygnalizacjaprzejazdowe).

@0xabad1dea

Does this train seem to move at a speed typical for that line? I'm kinda surprised that it seems not to have been notified by the signal before the crossing that the crossing is not closed properly (it wasn't closed properly at any point, because the barriers got broken off -- which is usually sensed -- essentially immediately).
