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 have another appointment that would be really hard to move, in terms of the kinetic energy requirements" is my favourite phrase of the week

Frist psot!
I today realized (yet another) reason why one must slowly start steam boilers: steam flow provides cooling of e.g. superheaters. Thus, if the heat output of the furnace is combined with lower-than-expected-at-that-heat-output steam flow, you'll overheat the superheater.

Okay. I really, really want /sees my posts in their home tab/ and /can see my locked posts at all/ to be separate things. I want to the former to be totally open again, and I want the latter to be more restricted than it is now.
Please, please can we make this happen? #mastodev

I'm looking for an USB XLR interface that's Linux-friendly. Currently I'm using Behringer UMC202HD and it's constantly problematic.
Boosts welcome!

It used to be the case in #Haskell that
:t 3
would give you
3 :: Num a => a
but
let x = 3
:t x
would give you
x :: Integer
because storing a value in variable forced the system to commit to a specific type.
Nowadays, though, the latter gives you
x :: Num a => a
What changed? I'm at a loss as to how to search the web for an answer to this one.
possible electrical energy shortage
I'm surprised that I haven't seen any appeals to clean the radiators in the fridges. (And now am trying to figure out how to get at mine.)

twitter quote on CS
there is NO field that more grievously overestimates the layman's understanding of what they do than computer science. if you do too much programming you ascend/descend to an entirely different plane of existence where you think that regular human beings know what linux is

Do you know of any text media (e.g. newspapers, but also blogs that aspire to journalism) that "show their work"? More precisely, ones that describe not only what they figured out, but also how they did that and, ideally, also the failed avenues. An example of a publication that goes in that direction (but not as far as I'd ideally want to see someone go) is Bellingcat.
Maybe you know journalists who publish (with a delay and redactions, for obvious reasons) log of all the research they're doing?
So, apparently swiss aviation regulator has restricted the number of passengers on a single historic aircraft as a permanent safety measure (in response to an accident from 2018).
If we ignore the effect on the price (by way of reducing total passenger throughout), I think this actually reduces safety. Ensuring safety of an aircraft takes work that mostly doesn't change depending on the number of passengers. Thus, aircraft with fewer passengers require more effort per passenger. So if the amount of passengers remains constant, we end up with more work (incl. more work for authorities) for the same level of safety.
Is there a mechanism (other than reducing the total number of participants) that could cause this change to improve safety?
I just learned of https://github.com/pixeldesu/fediverse-friendly-moderation-covenant (from the koyu.space's open singups announcement) and noticed the "this is from a bygone era" warning that you've added a few days ago. That warning confuses me: I don't understand what changes make it undesirable to adopt such rules. Would you mind elaborating a bit on that?
(Obviously feel free to not answer, or answer in any less public way if you prefer that.)
@moonbolt It just occurred to me that you might enjoy http://freefall.purrsia.com and might be unaware of it.

So, apparently not all dessicants are safeish to eat: CaO is apparently used as a dessicant (the reason it's not safe to eat is that it generated a surprisingly large amount of heat when reacting with water).
I'm curious why are dessicants from lime preferred (ever). The pictured bag is from a package of seaweed, which makes me doubly surprised: one might e.g. not notice that the dessicant bag has ruptured.
