@lkundrak Not sure, it got more confusing. Latest youtube news say they are starting to investigate sabotage, too.

Lets see. I still believe aircraft was not fully functional before it hit the ground.

@BeardlyDavid Nah, there are few of those around. They are still best "development board" available for camera development.

Did camera support on Librem 5 break with recent PureOS updates? That's bad timing for me :-(. #linuxphone #librem5

Jasne ze srst izoluje. Ale vnitrni prostredi ma ~36C a je v nem tepelny zdroj; vnejsi s trochou stesti min. A zvirata na leto linaji, to se asi evoluce spletla... https://www.seznamzpravy.cz/clanek/domaci-zivot-v-cesku-ve-vedru-nebrat-zvire-do-rozpaleneho-auta-a-rozhodne-nezkracovat-srst-280494

@mcepl @stepan "Jus in bello" je ten problem.

Jake nazory drzite uplne nevim, ale treba tohle bych nazval "bezpodminecnou podporou izraele": https://www.seznamzpravy.cz/clanek/domaci-politika-ambasadu-do-jeruzalema-presuneme-rekl-fiala-spor-se-vede-o-bezpecnost-277869 .

A minimalne namestkyne ministra zahranici Izraele dava dost jasne najevo, ze kritizovat Izrael je "bodnuti do zad", "lzive pomluvy": https://www.seznamzpravy.cz/clanek/domaci-politika-cilem-je-uplne-zniceni-izraele-a-vyvrazdeni-vsech-zidu-sveta-rika-politicka-277878

@mcepl @stepan Jasne ze situace na strednim vychode je slozita, a Izrael tam neni zdaleka nejhorsi akter.

Ale zacina byt jasne ze bezpodminecna podpora Izraele neni udrzitelna, a myslim ze za 10 let budeme vedet co se v Gaze deje ted, a nebude se nam to libit. Budou se nas ptat "jak jsme mohli prihlizet vrazdeni civilistu v Gaze" :-(. A tady se zatim debatuje jestli bychom nemeli presunout ambasadu do Jerusalema.

@agx No, you are right, X220 is old hardware. But I like the keyboard and it is powerful enough ... so I use it.

I assumed relative power of CPU, GPU and memory would be approximately similar... and clearly that's not the case. Which is a good thing, 512x384 might be doable on Librem 5's CPUs, but that's really quite low.

@mcepl @stepan Ano, na nektere veci nemame dostatecne kvalitni informace. Jestli jsou ty kupy mrtvych civilistu v Gaze omyl nebo zamer tezko zjistime. I kdyz tvrzeni Izraelskych politiku ze "Palestinci by meli zmizet z povrchu zemskeho" nam dava jisty navod.

Ale ze Izrael nema problem porusovat mezinarodni pravo vime dost jiste. Osady na okupovanem uzemi jsou valecny zlocin. Preventivni utok na Iran je ... no .... proste take neni v souladu s mezinarodnim pravem. Unosy? Jasne, naposledy unesli Gretu.

Je mozny ze v Gaze mezinarodni pravo dodrzujou? No, vyloucit to nemuzem, ale indicie mame :-).

@agx X220 is still second-best notebook, ever :-). Yeah, its old, but I kind of assumed TDP difference would make up for technology difference. Part is that Intel GPU insists on producing RGBA data, and I need RGB data.. and that was slowing things down. Anyway, good for Librem 5.

GPU on Librem 5 is actually faster than on X220? Good. I proved to myself that 1Mpix/30fps is possible. Now for the boring task of actually getting it to work... #linuxphone #librem5

@mcepl @stepan No, izraelskej pohled to asi vysvetluje... Jen na me porad blika "jasne, jasne, genocida je fuj, jenze kdo ted zrovna dela genocidu?" :-(. Doporucim tohle; ted uz by to autor asi napsal jinak, ale tohle aspon vypada jako nestranejsi pohled. https://www.nihilistanabalkonu.cz/l/co-se-to-deje-v-izraeli/

ISP on GPU is probably doable. If I'm lucky, it will do ~1Mpix / 30fps on Librem 5. #linuxphone Standby.

@martijnbraam Yeah, robot was suggesting PBOs. It would be great if someone with GPU experience could chime in, ideally saying "no, Librem 5 GPU can't handle 30MB/sec data flow" or better "yes, Librem 5 GPU can handle that easily, here is how" :-). Or maybe "No, can't work on Librem 5, but OnePlus 6 with this example ..."

Anyway, if someone has GPU experience, please chime in. If you know someone, you can show them the post or maybe boost :-).

@GuyDudeman #banglejs2 is useful. It kind of works pretty well. And add OnePlus 6 to the list.

debayer-gpu (git@gitlab.com:tui/debayer-gpu.git) tries to do debayering on GPU. But it seems OpenGL 2.1 is ... really not meant to do the computation. glReadPixels() can be used to get data off the GPU, but that does not have great performance. On PinePhone, you can only get RGBA out, but we really need RGB. Doing RGBA->RGB on CPU is easy, but it degrades performance further. I believe problem is that ISP produces a lot of data.

On Thinkpad X220, converting 400 images is like 12 seconds. If I do no processing in the fragment shader, it is still 10 seconds. X220 is able to process ~20Mpix/second on GPU. I don't believe Librem 5 will be significantly better.

If you believe GPU can be useful for task like debayering (mostly rearranging data with some additions and 2 matrix multiplies per pixel), let me know. 30Mpix/second on Librem 5 would be useful performance. #linuxphone
