#librem5

Did you ever have a look at the excellent #documentation of #Purism products?

docs.puri.sm/

One of the products of Purism is the #Librem5. The Librem 5 is a #Linux phone that runs the #PureOS operating system.

This phone is built up from the bottom to provide #privacy and software #freedom. No #surveillance by the manufacturer, free and #opensource (#FOSS) is their standard.

I use a Librem 5 as my daily phone.

Can you program GPUs and do you want to become a HERO? #linuxphone
community needs your help.

We are trying record video, and have most pieces working, but one is
missing: fast enough debayering. That means about 23MB/sec on #librem5.

Debayering is not hard; camera images have subpixels split on two
lines, which need to be corrected. They also use different color
representation, but that's fixable by some table lookup and two matrix
multiplies.

Librem 5 has Vivante GPU, 4 in-order CPU cores and 3GB RAM. My feeling
is that it should be fast enough for that. If task is for some reason
impossible, that would be good to know, too.

Image data looks like this

RGRGRG...
xBxBxB...
.........
.........

Task is to turn that into usual rgbrgb.... format. rgb = RGB * color
matrix, with table lookups for better quality. I can fix that once I
get an example.

I'm looking for example code (#pinephone would work, too), reasons it
can not be done... and boosts if you have friends that can program
GPUs. #gpu #opensource

Weekly GNU-like #MobileLinux Update (25/2025): Packed with Goodies
https://linmob.net/weekly-update-25-2025/

This week really was something: #postmarketOS ship 25.06 (which, among other things, adds systemd) and work to reverse-engineer #VoLTE, #FuriOS 13.1.0 lands with Open-Store support (for #UbuntuTouch apps) and plenty of other improvements, #PlasmaMobile share detailed log of all the fixes and improvements they managed to land in the past year (and what's to come), Jolla announce free #SailfishOS updates for all #JollaC2 customers, I managed to interview #Liberux about their Nexx phone - but there's way more still, including a packed Apps section. Enjoy!

Ervaren jullie ook #appdwang?

appdwang.nl/

Ik wil geen apps gebruiken die alleen beschikbaar zijn uit appstores van surveillancekapitalistisch #BigTech (Apple en Google). Ook wil ik alleen vrije #opensource-software (#FOSS) gebruiken op mijn apparaten. Daarom gebruik ik geen Android of iPhone, maar een #Linux-telefoon: de #Librem5.

Ik ben benieuwd, ervaren jullie ook appdwang? Wat vind je daarvan? Verzet je je er tegen? Zo ja, hoe? Zo nee, waarom niet?

appdwang.nlBied weerstand tegen appdwang! | appdwang.nlBied weerstand tegen appdwang en laat je geen apps opdringen! Op appdwang.nl vind je praktijkvoorbeelden en argumenten om duidelijk te maken wat je van appdwang vindt.

@smeg @smallcircles I'm from the Netherlands. I refuse to install WhatsApp, actually, I can't because I have a Linux #Librem5 phone.

I use SMS when people do not have #Signal. My experience is that people will install Signal after exchanging a few SMS's and you tell them about Signal. If you give in and install WhatsApp, other people will start contacting you on WhatsApp for sure, and Signal usage between you and your contacts will go down.

Following my request one and a half months ago: mstdn.social/@theDarky/1144151

By adding the following line to my #Mobian configuration:

/etc/apt/sources.list.d/experimental.list
deb deb.debian.org/debian experimental main

And by installing the experimental versions of the mesa Vulkan package:
sudo apt -t experimental install mesa-vulkan-drivers

Calling all analog film photographers! 🎞️ I've been working on Filmbook, an open-source app to help you keep track of your film usage. It's built with Rust & GTK4/libadwaita for a smooth & modern experience – and it even runs on Linux phones like the Librem 5 and Pinephone Pro! 📱

The first version is ready for testing, and I'd love your input on what features would make it even better! Join the community & help shape Filmbook: https://codeberg.org/bjawebos/filmbook ✨ #filmphotography #analogphotography #rustlang #gtk #opensource #community #testing #featureideas #librem5 #pinephone #linuxphone
