If you want to hear about phone cameras -- recording from my FOSDEM talk is now available https://mirrors.dotsrc.org/fosdem/2026/ub4132/NZCWQJ-photos_and_video_recording_on_mobile_phones.av1.webm .

Kdysi jsem programoval jizdni rady.. a v jedne versi jsem mel chybu, ktera vyrabela teleporty.

A ted maji tu chybu na idosu:

Bus 169223 273 JAMI LINES s.r.o.
18:20
Praha,,Černý Most 1

18:29
Hradec Králové,,Terminál HD H2

Jo, vypada to lakave. Ne, tenhle spoj nedoporucuju.

Bohuzel, nektere obce pod zaminkou "bezpecnosti" vybiraji mytne. Viz treba ricany s radarem mezi poli. Takze tady vlade fandim... https://www.seznamzpravy.cz/clanek/domaci-zivot-v-cesku-mezi-obcemi-a-vladou-doutna-spor-o-miliardy-z-pokut-za-rychlou-jizdu-297543

Nejlepsi snih na bezky je na silnici Stihlice -- Vyzlovka.

Gnome Software has this "wheel" button on packages... you press it, and it updates the package. That's not what I would have guessed it would do.

What is worse phone (OnePlus 6 with PostmarketOS) no longer sees the wifi. Any ideas besides "wipe and start again"?

This is what my fosdem talk will be about... and also fallback if hdmi from phone fails. My notebook with real slides is too far away due to mistake.

thank you

I'm at fosdem. Talking about phone cameras at saturday. Feel free to join!

gsd-color. Not sure what it is supposed to do, but what it does is turning phone into hand warmer. killall -STOP gsd-color seems to fix it. #postmarketos on Samsung S4 mini VE.

Ano, jsme v cesku. Tak proc nechavame japonce, aby tu rozdmychaval nacionalismus? Proc neodsoudime Okamuru? Aha, on se pred soudem schovava v parlamentu :-(.

Mozna jste si vsimli zjevnych podvodu na FB. Je videt ze na reklame se da vydelavat... i kdyz si reklamu zada podvnodnik. Dalsi dobry trik je, podvodnikum proste jen dat vyssi sazbu. Jo. A kdyz kliknete na jednu, tak jste asi na podvody nachylny, tak proc to nezkusit vickrat. Jak to rikaj "adblock je antimalware"?

Ja jsem na social.kernel.org/pavel .

Turns out #opencv is nice and easy to use. I now have fairly complete ISP (image signal processor, thing that turns raw bayer picture into nice looking jpeg) in Python in 212 lines of code.

Gentle charging should be possible on #oneplus6. Currently experimenting with code at gitlab.com:tui/tui.git ofone/charger.py.

I had many phones. Some were good, some were bad, and some were meh. Siemens sl45i looked like good phone, but it was not, partly because they forgot to debug it. Ericsson t68i was nice (70? grams), bluetooth was improvement. Nokia 6230 was very nice phone (99 grams), Nokia 6230i was downgrade, and Ericsson K700i was not a good phone. UI was not great and it would not hold in one piece.

I had HTC Dream (aka T-Mobile G1). Having Linux inside was "cool" but it definitely was not good, and was not a phone. Nokia N900 was better, Linux worked a bit better, but still not a phone. And than it got ... worse? Motorola Droid 4 is better version of N900, but bigger again. Pine Phone, Librem 5, OnePlus 6 ... yes, each one is better computer, but neither is really a good phone.

And then I got Geeksphone Keon (Firefox OS). It runs Linux (kernel 3.4 or something), but rather old one, and is certainly not a good computer, but it started feeling as a phone, again. Reasonably battery life (few days), and it would actually fit into pockets I had available when riding horses. I liked that one. 120grams.

And now I have a new toy (actually few "new" toys, thanks!) that starts to feel like phone. Samsung S4 mini VE (110 grams) is really nice phone. Small enough and can last few days (with LineageOS), and with #postmarketos it seems to be pretty good computer, too. It runs mainline kernel, and most of the stuff mostly works (except cameras). Wow! Once again, I have phone I like (or four).

Samsung was not even too evil when creating the phone, so you can just hold buttons and enter bootloader. Certainly improvement from OnePlus 6, where I will likely never get rid of red errors during boot. There is a bit of evil in the details, that "VE" or "value edition" is important. That is i9195i, which is very, very different from "S4 mini" or i9195. Mainline support is very limited for i9195 -- you will not get touchscreen, for example.

Any help would be welcome. And if you have S4 mini you do not need, I may be able to use it.

Earlier today I learned that pip includes a bunch of telemetry data in the HTTP User-Agent header for every request it makes, and has for >10 years (with increasing amounts of info): https://github.com/pypa/pip/blob/545eda389c41478e2f99d23212254d757d8c2cef/src/pip/_internal/network/session.py#L109
Not only is this not opt-in (as any telemetry should be), but there isn’t even an opt-out. I’m still shocked and not sure what conclusions to draw from this, except: This is not okay!

I remember there was quite an uproar when Go tried to add opt-out telemetry a while back, and rightly so. How did I never hear about Python doing this before? Sure, less details, but still sending telemetry without ever asking for consent.

I like #Python, I want to keep using it, but can I if core tooling ignores user consent like this? And what other key development tools (Python or otherwise) have things like that and I just haven’t noticed yet?

"Írán: Bezprecedentní výpadek internetu v Íránu, který nebyl vyřešen ani krátkodobým obnovením tzv. národního internetu, způsobil rozsáhlé narušení bankovnictví, obchodu i zásobování a uvrhl miliony lidí do vážných existenčních potíží. Ekonomické škody jsou odhadovány na desítky tisíc miliard rijálů." Na desítky tisíc miliard rijálů, coz bylo vcera asi tak 13Kc, a dneska je to neco kolem 70ti haleru? :-).
Jinak bych pouvazoval o uvadeni takovychhle cisel ve vedeckem zapisu, "zhruba 10^13 rijalu"... nebo mozna v dolarech :-).

Jak se vodi kun? Na voditku kone vodit umim. Koni to nevadi, oba jsme spokojeny. Na volno s konem jit taky umim. Oba se musime soustredit, pamlsky mizi, ale dobry. Co s konem na ohlavce ale bez voditka? Muzu ho capnout u huby, a par kroku takhle ujdem, ale konovi je to nepohodlne, a zacne to davat najevo.

Jake jsou dalsi moznosti? Chytit ho za ucho? Za cuprinu? Polozit ruku na kohoutek a snazit se ho ridit tak?

Tak to vypada, ze na me uz rehta i Soson. Jako jo, ono to asi svadi, dostane povel, udela povel, ja reknu ze "jo", a nez mu pristane pamlsek v hubicce, ma skvelou sanci udelat 'hu hu'.

Ten debilni uplatnej sasek si vzal nobelovu medaili. Ze ho na strednim vychode uplati Boeingem ... to by mela byt ostuda, a mel by za to jit sedet, ale .. Boeing je Boeing. Ale ze se ten stabilni genius necha uplatit medaili? Ne cenou, medaili? No snad to v tomhle pripade povede k necemu dobremu, a snad ten kriminalnik uz bude brzy zavrenej nekde kde nebude skodit. A vlastne, nevadilo by mi kdyby odesel za "svym stvoritelem". Vetsina jeho mozkovych bunek uz to udelala.

Už zítra se koná hackday!
13. 1. od 10:00 až do večera!

Těšíme se na vás v Karlíně!

What kind of scam is this? It seems to be full of false news, and ... more suprisingly, what youtube suggests when opening this is more false news? https://www.youtube.com/watch?v=adPQBkvnwwg -- leads me to further false news as https://www.youtube.com/watch?v=S6XMIvFwjwA ...? Have you seen this before? What is this?
