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 totally agree with a lower estimate of, say, "<10% chance of practical powerplant within 7y", but am very surprised by the "decades" one (which I understand as ~30years).
> April 1932 - first time an atom was split by humans
For fusion something similar has happened decades ago. (You are pointing at the experiment that involved causing fission without a chain reaction. It wasn't understood for couple of years after it that fission actually happened.)
I would put "getting energy-positive[*] fusion" in the timeline roughly around CP-1's criticality.
> December 1946 - first nuclear reactor hosting a self-sustaining, controlled chain reaction
Wasn't that CP-1? It reached criticality in 1942.
It took 12 years between first sustained chain reaction in Chicago Pile-1 and the first grid-connected nuclear power plant becoming operational. It took further 3 years until the first NPP that produced tens of MW of electrical power (which today would on the smaller end of spectrum). That was under just-postwar conditions. Do you expect timelines to be longer now?
When you don't realize that you've bought disks with quite high vibrations at seek time:
(The doohickeys are from https://www.thingiverse.com/thing:1774380. All in all works surprisingly well; apparently ~all the audible seek noise was coming via the case due to impedance matching.)
@sargent Do you have examples of people doing the same thing in real life?
@lauren Ah. Yeah, that happens on the receiving side (i.e. the instance that receives such a post) and not on your instance's side, so there's really ~nothing else you can directly do about that :/
@lauren Why do most (all?) your posts include an all-white image?

Playing with GCP's Confidential Compute stuff, and I feel like the advice in the docs to verify that the VM has confidential compute enabled by (checks notes) asking the metadata service whether the instance has confidential compute enabled is maybe missing the point a little
@grzgrz Huh. Dziwne, że interesuje ich BMI ~w ogóle, a nie ~tylko waga.
@grzgrz W sensie że za mało ważysz? Ojej, nawet u mnie na to nie narzekali.
@crschmidt Note that lack of quote-toots is a question of your instance: ActivityPub does have support for them (instances will IIUC at worst render the quote as a link if they don't support the thing at all), and some instances do support publishing quote-toots.

@kwf So what can you do? Well, optical fibers happen to be excellent electrical isolators. Electric currents and magnetic fields go hand in hand. So instead of winding an electrical conductor around the transmission line, you wind some length of Faraday active optical fiber around, send polarized light through it and measure the amount of polarization rotation on the other end: That's an optical current transformer. https://en.wikipedia.org/wiki/Fiber-optic_current_sensor
> boosted with the BA4/5 booster
If you don't mind me asking: in Switzerland? I might be totally confused, but I thought that the bivalent boosters here are bivalent with BA.1 (based on e.g. https://www.bag.admin.ch/dam/bag/de/dokumente/mt/k-und-i/aktuelle-ausbrueche-pandemien/2019-nCoV/steckbrief-impfstoffe-herbst-winter-2022.pdf.download.pdf/Steckbrief_Covid19Impfstoffe_DE.pdf)
@grrrr_shark This is likely way overengineered, but (a) on the off-chance it's not (b) because it's an interesting solution to a different problem: If you want to be reminded when you do some particular motion with your wrist, there are bracelets that detect a prerecorded motion and vibrate (they are usually used to combat tics).

Which seems to be self-certifying with extra steps that do not make lying harder, so I don't see why not simply allow self-certifying.
@ERDonnachie @danyaalraza@med-mastodon.com
To be fair, this is still weird. If I have something that looks like a cold it's quite plausible to take more than 3 days to resolve and getting myself to a doctor would often be harmful for everyone involved. (Also, what would the doctor even be able to certify? "The patient presented sneezing and claiming a headache"?)

When I held my notorious/legendary "Jay Ward Film Festival" at UCLA in the early 80s (attended by Bill Scott, June Foray, and more!), Bill (the voice of Bullwinkle and so many more familiar voices) told a story of would-be "censorship" on "Rocky and His Friends" (1959-1964).
Seems that they had done a sequence where Rocky and Bullwinkle are in a pot being cooked by natives. The sponsor went nuts. "You can't have cannibalism on a kids' show!" the sponsor proclaimed.
The reply: "Is it really cannibalism to cook a moose and a squirrel?"
The bit stayed in.
I have an audio recording of the entire proceeding, including a live performance and amazingly prescient Q&A session. I really need to get it back online.
It seems that the definition of "direct participation" was already very much subject to precedent and complicated. https://www.icrc.org/en/doc/resources/documents/faq/direct-participation-ihl-faq-020609.htm provides some interesting nonobvious examples
Interestingly, if one reads the interpretation provided in https://www.icrc.org/en/doc/assets/files/other/icrc-002-0990.pdf (specifically pp. 52-54), it seems to imply that setting up automatic observation posts that will report enemy movement should be considered to be _in_direct participation.
@mjg59 Well, u2f with some extension to provide {en,de}cryption too.
@mjg59 So, would all those usecases be satisfied by a u2f key built into the device?
