@askihk @sibrosan @xChaos @tymoty Tady asi doporucim neco jako "PBS spacetime" na yt? O vesmiru toho vime dost, ale "utvar" bych asi nepouzil, a bylo by potreba rozlisovat pozorovatelny vesmir.. No a pak tam bude nejaka filozofie jestli casti vesmiru ktere nemuzem pozorovat jeste tedy jsou nas vesmir a tak. Proste je to celkem slozite :-).

I'm playing with angular velocity sensor on #librem5. I can get some data from sysfs, and they show hw is working, but interface is not fast enough for anything useful. I did not get triggering / buffered mode to work so far. Code is at git@github.com:pavelmachek/Espruino.git .

@z3ntu Ok, so apparently it is possible to buy Fairphone 5 and 6 new here, for similar prices (cca EUR600). Second-hand Fairphone 5 may be available for ~EUR400, and new Fairphone 4 may be available for ~EUR300.

Having main camera available with open-source drivers sounds very cool and may be reason for Fairphone 4 ... unless same is true for the newer models...?

@tymoty Is Earth the centre of the Universe? Is there centre of Universe? You may want to select better example, as, well, Earth is almost as good centre of Universe as any other. (Ok, there's cosmic microwave background and Earth moves against it, but what does not?)

@dcz You are partly right.

OTOH JITs are optimized for speed, while cargo build is optimized, well, for best optimized result. If you can get 2% faster output executable for 30% slower compilation, compiler might do it.

@z3ntu Aha, that's it, thanks. If you want video recording & autofocus, take a look here: https://gitlab.com/tui/tui/-/tree/master/ccam?ref_type=heads . It can also take photos, some work will be required.

I wonder how easy is it to get Fairphone 4 in czech republic?

@z3ntu Aha, so my recall was that problem with OnePlus6 was not sensors, but phy inside the SoC, and that it was common problem accross Qualcomm chips. Look like I was wrong.

@dcz Well. You are building x86 code on one side and arm code on other. More fair benchmark would be to cross-build same demo for, dunno, powerpc.

@z3ntu If I understand things correctly, that's a very good news for OnePlus 6, too? And maybe a TODO item for me, as Droidian is likely not going to work for these experiments.

@z3ntu @jbaersaft Slower charging also means battery lifetime is longer. Limiting charge to 80% is even more important. I have some experiments at https://github.com/pavelmachek/unicsy_demo/tree/master/bat and elsewhere.

@QuadRadical @z3ntu There's also AF support for Millipixels, Megapixels and Clicks machine, to mention a few. Last one can do PDAF. But there's a lot of difference between "AF support" and "good AF support".

Prasatko od baterky je takova zvlastni vec. Ono neni objekt, takze vlastne neexistuje, a muze porusovat fyzikalni zakony. Treba dokaze fakt neuveritelny zrychleni, a muze se pohybovat nadsvetelne.

Chapu, ze je to zlutakovi podezrele. Velke prasatko mu nevadi (nevadilo?) ale kdyz se zaostri... tak se zlutak pokusi take pohybovat nadsvetelne. Nastesti neuspesne.

@jan @xChaos Tak reasoning je neco jineho, ne? A AI hype je lepsi ignorovat. Jsou to LLM, na modelovani jazyka jsou dobre, na odpovidani na otazky min.

(Asi by slo zkusit dat vystup modelu jinemu modelu, at to zkusi overit jestli to dava nebo nedava smysl, ale...)

Mel bych vzit vyjizdku, tak jdu pro kone do vybehu. Dva kone mam, ale kde je zlutak? Ze by se schovaval pred vetrem v lese? Ne, tady neni. Chytam kone a koukam, ze zlutak uz ceka u vychodu. No, to je od nej hezke, ale jak to sakra udelal? Musel se nekudy protahnout kdyz jsem sel k lesu...

Pockat, ne. On neni ve vybehu u vychodu, on je za paskou a chce dovnitr. No, porad je tu otazka "jak to sakra udelal". Necham ho pustit dovnitr, a kone ho vitaj rehtanim. Tedy krome Medi, ten se ho snazi z vybehu vyhodit. Aha, asi byl venku dyl.

No nic, obesel jsem vybeh, v uzasnym stavu neni, ale uplne spadlej taky ne, a zlutak se elektriky boji. 10kV tam uplne neni, ale neco citit tam je. Dve mista jsem se pokusil vylepsit, hral jsem si na detektiva a zkusil jsem vyslechnout souseda, tak treba se utek nebude opakovat. Pokud vim tohle byl druhej. Potom dostane elektronickej sledovaci naramek, hadam.

@xChaos @jan Tohle myslim nebude jednoduche. Ona pravdepodobnost vety je tak nejak umerna 1/e^delka_vety, takze tam je hodne nul. AI ktera nehalucinuje by byla super. Vlastne AI ktera nehalucinuje je strasne jednoducha, ale AI ktera je uzitecna a zaroven nehalucinuje by byla super :-).
