I am an ordinary person, but circumstances have turned my life into a daily battle. Cold, hunger, and fear have become part of our days. My children need safety… they need a roof to protect us and warmth so they can sleep without tears. Any donation, no matter how small, can change our lives and ease our pain. Please help us live with dignity. May God reward you 💔
Overnight, the Astrakhan gas processing plant in Russia was reportedly struck, triggering a large fire. Russian Defence Ministry claims it shot down 38 drones over Astrakhan Oblast during the same period.
Quiz del lunedì un po’ macabro: quanto tempo impiegherebbe per congelare completamente un corpo umano esposto allo spazio profondo, privo di protezioni come vestiti o tute spaziali?
La risposta esatta è “più di dieci ore”. Nel vuoto i corpi umani non esplodono né tantomeno congelano immediatamente, al contrario di quanto si vede in alcuni film di fantascienza.
Abbiamo la prova diretta che i corpi umani non esplodono quando vengono esposti al vuoto perché è quello che accadde nel 1971 all’equipaggio della Sojuz 11. Durante il distacco dalla stazione spaziale Saljut 1, si aprì per un errore nella procedura una valvola di scarico dell’aria e la navetta si svuotò completamente: i tre cosmonauti morirono per mancanza di ossigeno, ma i soccorritori che tentarono invano di rianimarli dopo l’atterraggio riferirono che “sembravano addormentati”.
D’altra parte, il congelamento richiederebbe molto più tempo di quanto si potrebbe pensare perché, anche se la temperatura di base dello spazio è poco sopra lo zero assoluto, la mancanza di aria fa sì che non si possa scambiare calore per convezione, ma soltanto per irraggiamento, cioè attraverso l’emissione di onde elettromagnetiche infrarosse, un processo fisico che alla temperatura del corpo umano è molto meno efficiente della convezione.
L’umidità superficiale del corpo umano evaporerebbe rapidamente, ma gran parte dell’acqua contenuta all’interno resterebbe intrappolata. Una volta che il corpo fosse arrivato a zero gradi Celsius, l’acqua rimasta all’interno dovrebbe lentamente cedere all’esterno il calore latente di fusione/solidificazione e gli strati esterni già congelati funzionerebbero da isolante, rallentando ancora di più il processo.
Se poi il corpo fosse esposto al Sole o a un’altra fonte di calore significativa, il congelamento diventerebbe ancora più lento o potrebbe non avvenire per niente.
Nonostante la realtà sia meno violenta dei film, se avete in programma una gita extra-atmosferica, indossate una buona tuta spaziale!
OK la cosa della mancanza di esplosione mi sorprende: sapevo che il congelamento avrebbe preso un sacco di tempo perché conosco i meccanismi fisici del raffreddamento, ma pensavo che ci sarebbe stata l'esplosione e quindi ho fotato per l'ultima opzione. A cosa è dovuta la mancanza di esplosione? Cioè, dove fallisce l'ipotesi alla base della miscredenza, che se non ricordo male era basata sulla questione della pressione interna vs pressione esterna?
@oblomov il fatto è che la cute umana è abbastanza robusta ed elastica per resistere alla differenza di pressione. Altro discorso sono per esempio i polmoni, che fanno una brutta fine.
ah m'era venuto un sospetto, ma con tutti i buchi che ci sono mi aspettavo comunque scene abbastanza splatter (tipo cervelli spremuti fuori dagli occhi, intestini espulsi e roba del genere), non certo “sembrava che dormissero”
No, per mancanza di spazio e di potenza del veicolo non avevano le tute spaziali, altrimenti sarebbero sopravvissuti. Per questo si può dire che l'esposizione al vuoto non fa danni clamorosi, almeno all'esterno. Altro discorso i polmoni.
@oblomov No, infatti, la realtà non è così splatter. Nel 1965 un astronauta americano fu esposto per errore al vuoto per 14 secondi durante un test e perse i sensi ma non riportò danni permanenti.
@andrea_ferrero Ah, ho capito il mio errore... Stavo considerando il corpo come una sfera uniforme e cadevo in una stima di meno di un minuto... 😂 La stratificazione mi riporta al comfort della risposta che avrai dato intuitivamente. Grazie per il trivia!
Good morning fellow Mastos and hello Monday. MrsD is out today, she has a walking group Christmas lunch following a walk, then this evening she is ballet dancing! I'm off to the shops again, the nest of tables she bought yesterday was so useful, she wants another set!
Have a great Monday, all contradictions aside. Have fun, lots of laughs, eat well. Take care.

I’ve never thought about it this way, but it’s almost certain that my nonchalant default position about “does LLM training violate a social contract about credit in open source” is related to the baseline fact that I’ve devoted my entire life to open source and appear in (to a rounding error) zero CREDITS or AUTHORS files. My contributions have been stripped, but it wasn’t by AI.
@yoasif@mastodon.social @mcepl@en.osm.town both Matej and I have spent the overwhelming majority of our adult lives supporting open source in non-credited non-coding roles.
What’s totally conscious: that I’ve been explaining to lawyers, engineers, and students for 15 years that every device they own has an attribution file and to a rounding error no one, even the developers, ever reads them. Their original, noble, purpose has morphed into a box-checking exercise performed by multi-billion dollar corporations for their lawyers, not for developers. And that long predates Copilot.
To be clear, that’s super-problematic! But it’s not problematic because LLM; it’s problematic because the mechanism we invented in the 1970s and 80s to create human relationships didn’t survive the transition to modern, mega-complex, mostly-open systems. LLMs are at worst the moment where we had to collectively acknowledge that the emperor is clothed in unread READMEs.
If the purposes of a system is what it does, the AUTHORS/CREDITS are not a benefit for the people listed but rather a social function: an outsourced (poor) substitute for a functioning register of copyrights which would *limit* the universe of potential #copyright claims (and eventually be instrumental in a restoration of the "limited Times" in the Progress Clause).
@nemobis A bit of a tangent, but I have for years wanted someone to build better human-focused editor recognition for Wikipedia. Ironically (given this conversation) maybe I can finally build a mockup with Claude Code ;)
We sure need more experimentation there! What I liked the most about WikiTrust back in the day was that it would surface the authors of a passage in an article that caught your attention.

Milano festeggia la gara numero 200 contro la Virtus Bologna con una vittoria per 74-63. L’EA7, nonostante le numerose assenze, si affida a un grande Armoni Brooks (23 punti) e a una difesa solida nei momenti chiave.
Overnight, Russia launched 153 UAVs (Shahed, Herber and others) from multiple directions. Ukraine’s air defenses shot down or suppressed 133 of them across the north, south and east. 17 UAVs struck 10 locations. The attack is ongoing with several drones still in the air.
Look, I know I like to present myself as a serious #photographer, but on New Year's Eve this gorgeous boy will become the new member of the family, so buckle up for a lot of #puppy pictures.
The title of the poem is in normal orientation at the top of the image. The poem itself is typed in lines at a slight angle to vertical - each letter of a word below the previous letter, and each line to the right of the previous line. The lines aren't precisely straight or parallel. The shape of the poem suggests rain.
Sorry, my French is good enough to read the poem, but not good enough to add this description.

It's now, as the first pre-release of #Linux 6.19 is out – which leaves plenty of time to find, report, debug, and fix any problems that those distros otherwise will encounter when they switch to 6.19.y in about eight to ten weeks. And testing is not even hard, as easy-to-install packages with pre-built mainline kernels exist for all three distros[2].
In case you want to play it a bit safer, delay testing by one week till -rc2 is out – bugs that lead to data loss introduced before -rc1 are extremely rare but will almost certainly have been found and fixed by then.
Anything up to 6.19-rc6 (five weeks from now) is still okayish, but less ideal.
The sixth -rc is your last good chance to test. Linus by then wants all regressions that have become known since the beginning of the 6.19 cycle fixed – but in case some were missed or not reported yet, there is still enough time to report, debug, and fix them before they reach those distros.
Testing any later is often too late: most bugs then can't be fixed anymore before those distros will switch to the 6.19.y series, which will happen within one or two weeks (in the case of Arch and Tumbleweed) or three to four (Fedora) after 6.19 is released.

#Python folks, let's say I want to configure a CI build (perhaps a Github action) that uses the *MINIMUM* version of Python and dependencies specified in a pyproject.toml file for the test. I.E. to ensure that features not present in those versions aren't used in new code added to a library.
