By impure state I meant a probability distribution over (pure) states. Consider two probability distributions over single-qubit states: one of them uniform (i.e. invariant under any unitary transformation) and the other one assigning probability 1/2 to |0> and to |1>. Any measurement made on these will provide same probability distribution of outcomes, because they have the same density matrix (density matrix is expected value of the projection operator onto the (pure) state, where the expectation ranges over the probability distribution from which the state is drawn).

@dpiponi

There is a small(?) difference that this reasoning makes apparent: in the quantum setting, if you are given an infinite stream of i.i.d.-and-unentangled impure states, you can't estimate the probability distribution they come from. That's because states with the same density matrix provide same distributions on outcomes of any measurements (and the density matrix of the i.i.d. sequence is a function of the density matrix of a single element).

Hm~ I have a somewhat interesting comment for you, which immediately brings up a fiction recommendation in my mind, which is IMO much more interesting than the comment. Sadly, the comment coupled with the recommendation is a significant spoiler, so let me just give you the latter: "Steerswoman" seried by Rosemary Kirstein (warning: unfinished series, but the author's alive) is a fantasy-or-sf series that follows some people who value curiosity very highly. A random review that I think describes the books well: https://escapepod.org/2011/11/19/book-review-the-steerswoman-by-rosemary-kirstein/

@ninawillburger Do we know how they were made? (I'm curious whether the ridges were added at high temperature, the space between them emptied at high temperature, or the space between them emptied at low temperature.)

@biffvernon@mastodon.online Also, this wasn't the case in Switzerland a few decades ago and improved by explicit efforts with exactly that goal.

Nie mam jednej (ani nawet kilku) ulubionych książek z dzieciństwa. Losowy podzbiór (trochę zbiasowany w stronę niefikcji) książek, które lubiłem, nadal pamiętam, i o wielu z nich podejrzewam, że miały niepomijalny wpływ na mnie:

"Lilavati" Jeleńskiego
Różne powieści Verne'a (pewnie powieści Hala Clementa też by mi się podobały w podobnym wieku, gdybym je wtedy znalazł)
"Jak myśleć logicznie" Ruchlisa
Pewien podręcznik do Quick Basica, którego autora nie pomnę.
"Zabić Drozda" Lee
Różne książki wydawnictwa Dorling Kindersley (mieli wiele różnych serii książek o jakiś urządzeniach, albo innych kawałkach świata, zwykle bardzo wizualne)
"Dzieje świecy"
"Może dobrze, może źle" Barkera (z perspektywy czasu widzę, że to jest dalece nieidealne, ale mimo to imo godne polecenia)
"Rozmowy ze zwierzętami" Lorenza
"Genetyka w obrazkach"

@isomer Doesn't this just at worst delay your collection of timestamps, as long as you have an uninterrupted stream of packets being sent? (I'm not sure what you want to use this for, and so whether that's no inconvenience, some inconvenience, or an insurmountable problem.)

@biffvernon@mastodon.online

Nit: Inside the city of Zürich there are 4 public baths _in Limmat_ (and 5 more in the lake from which the river flows). https://badi-info.ch doesn't mention any baths on Limmar outside of the city (though there surely are unofficial beaches there and there's lots of people floating downriver on inflatable unicorns in the summer).

BTW. Swimming in the spot depicted on the photo is usually forbidden (due to existence of boat traffic and various places where collisions would be hard to sufficiently surely avoid); the photo was taken during a once-a-year event that involves forbidding boat traffic from using that part of the river for a change.

@rysiek Also, I'm somewhat conflicted about what social contracts I'd want around defining things.

On one hand, being explicitly imprecise has value. This is ~always part of figuring out what precise statements are true.

On another, being imprecise trashes modus ponens (because you end up doing the logical implication equivalent of the game of telephone).

An obvious contract that seems to satisfy both is to expect everyone to be explicit when they are imprecise. However, a failure mode of that is that people often don't want to bother being precise and this doesn't create ~any incentives not to be imprecise all the time.

@rysiek It sounds like you are describing an example of https://en.wikipedia.org/wiki/Motte-and-bailey_fallacy (I mention this because knowing names for things is sometimes useful, like in that old joke/anecdote about flowers that are more easily recognized if one can name them.)

@sargent Isn't gumroad such a tool?

@HerraBRE I once managed to cause a leak just next to the valve. I suspect that I inserted the valve not perpendicularly enough and the force from the nut that forced it perpendicular was causing it to rub against some part of the wheel there.

@SwiftOnSecurity

Is the BIOS serial number related to the machine's MAC address?

@HerraBRE The problem is solved unless all this manipulation actually added a leak to the tube :)

@bagder So the next one is going to be Klapaucjusz? :)

@bradfitz You can also use Nix to generate a VM image. If you have (or want to have) Nix available somewhere outside of that VM that is likely simpler than going through installation.

@lambdatotoro @uriel @juglugs

I'm confused by the lack of any explicit statement about fish there. Is the weird understanding of "meat is forbidden, unless it's meat of a fish" something that local episcopal conferences promulgate?
