Subject: Sasha Levin is halucinating, non human entity, has no ethics and no memory
Hi!
So... I'm afraid subject is pretty accurate. I assume there's actual human being called "Sasha Levin" somewhere, but I interact with him via email, and while some interactions may be by human, some are written by LLM but not clearly marked as such.
And that's not okay -- because LLMs lie, have no ethics, and no memory, so there's no point arguing with them. Its just wasting everyone's time. People are not very thrilled by 'Markus Elfring' on the lists, as he seems to ignore feedback, but at least that's actual human, not a damn LLM that interacts as human but then ignores everything.
Do we need bot rules on the list?
Oh, and if you find my email offensive, feel free to ask LLM to change the tone.
Best regards,
Pavel

@NekoCWD Hi! libcamera people told me you are working on autofocus for libcamera. I got that to work with great hacks at Librem 5 at one point: https://lists.libcamera.org/pipermail/libcamera-devel/2025-April/049734.html . Is your code public somewhere? What hardware are you using?

How to install librem5 without an installer?
root@pureos:~# mount / -oremount,ro
mount: /: mount point is busy.
root@pureos:~# echo u > /proc/sysrq-trigger
root@pureos:~# mkdir /bar
mkdir: cannot create directory ‘/bar’: Read-only file system
root@pureos:~# cat /dev/sda > /dev/mmcblk0
root@pureos:~# sync
bash: /usr/bin/sync: cannot execute binary file: Exec format error

Hey, world. I need Mobian installer for Librem 5, but the directory where it should be is empty. What is going on?

https://www.seznamzpravy.cz/clanek/zahranicni-trump-mluvil-se-zelenskym-o-jeho-malem-problemu-summit-nato-2025-280240
Ještě pár dní před summitem nebylo jasné, zda ukrajinský prezident Volodymyr Zelenskyj vůbec přijede. Bez jistoty, že si na něj americký prezident Donald Trump najde čas, totiž cesta nedávala smysl. V podobné situaci se ocitl i na začátku měsíce, kdy kvůli G7 letěl do Kanady – jen aby zjistil, že Trump ze summitu odjíždí dřív, než k setkání dojde.
Tentokrát bývalý prezident USA oznámil možné setkání jen neurčitě – během ranního letu na palubě Air Force One, který mířil do Nizozemska.
Byvaly prezident USA? Uniklo mi neco duleziteho? :-)

@mirabilos @eevee Actually, you'd be surprised. I ran the modem locally on a cellphone, so I know the power consumption.

@mirabilos @eevee Yeah, because LLM clearly use more resources than human doing same job would.

@karolherbst Nah. How would that work? Is there any other country where they have majority system and more than two parties?

Hi!
I asked for help with ISP...
Can you program GPUs and do you want to become a HERO? #linuxphone
community needs your help.
[...]
and I got help. Both from humans and from language models. Quickly it
turned out Librem 5's GPU is fast enough for debayering at 24fps,
0.8MP and data can be transfered enough fast enough. Soon, it turned
GPU can use full 13MP image as a source, scaling it down to 0.2MP for
gstreamer mp4 recording.
This opens possibility to do phase-detection AF and digital
zoom. Librem 5 is not fast machine, its CPU/GPU/RAM is slower than
Thinkpad X220, for example.
Then I set out to investigate "how much of an ISP can I do" and it
turned out I did not yet find a limit.
So far I did black level, some attempt at denoise, three matrix
multiplies and gamma correction. (CPU could do black level + gamma +
one matrix multiply, almost, if I did vector instructions and a lot of
care). I don't know how much my GPU is loaded, but at the moment I
believe ISP on the GPU is the way to go.
Yes, I'm doing simpler debayer than usual, through not as simple as
explained below. I believe that's right choice when 13MP image is
available.
Code is at
https://gitlab.com/tui/tui/-/tree/master/icam?ref_type=heads . It has
some pretty rough edges. But get Librem 5, it is worth it :-).
Special thanks to @dos Sebastian Krzyszkowiak and @datenwolf.
Best regards,
Pavel

@dos I don't have much experiences with GUI programming, so I was looking for suggestions. I've got dma-buf handle but would not know what to do with it in gtk, and maybe SDL is better match. Or perhaps stick to original plan and do user interface ("take picture" button etc) in another process.
