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

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:

Just landed on Indiegogo: crowdfunding for a £1,100 per unit new Linux phone, the Liberux NEXX.

The specs are impressive, and it is the kind of thing I'd love to support, but wow that's a lot of money.

More than I'm willing to gamble, frankly, by a significant margin, but perhaps it might appeal to you!

So, when these Apple devices die (or rather, when the updates have slowed them down enough, and the battery has depleted to the point of not getting through the day - which should be next year or the year after, if the pattern holds)… my next devices will be some of the following, and I’m looking forward to the challenge of getting them to work… any recommendations?

Phone options:
- Pine Phone
- Fair Phone
- Murena
- Librem
- Pro 1x
- Volla Phone
- SageTea XFone

Watches:
- Any of these with AsteroidOS: wiki.asteroidos.org/index.php/
- PineTime
- ZSwatch:
github.com/ZSWatch/ZSWatch

Any suggestions or advice?

The "Mobile Linux"/"Linux Mobile" discussion feels like a rehash of the "Open Source" terminology discussion in the 90's that led to more diverse terms (e.g. FLOSS).

I propose:

#linuxmobile / #mobilelinux as umbrella terms for all efforts at bringing the standard Linux ecosystem to any mobile device (e.g. also tablets)

#linuxphone for a phone running standard Linux ecosystem parts *predominantly* (e.g. allows Android kernels and Halium)

#FLOSSPhone for a phone with no proprietary parts

When my #mobile phone will be KO, I'd like to have a true (#GNOME) #LinuxPhone … and the FuriPhone #FLX1 by @furilabs seems to be a good candidate 🤓

Built on the Gigaset GX6 :
- Removable battery
- 2 SIMs slots AND micro SD
- Robust
- B1, B3, B7, B20 and B28 bandwith (French 4G)
- Debian GNOME + Android layer
- Jack input …

… but expensive and maybe a bit too big 🤔

An opinion ?

Mecha Comet - Modular Linux Handheld Computer

Je crois que j'ai enfin trouvé mon futur smartphone. En espèrant que ce projet décole. Domage que l'écran soit petit.

The Comet is a handheld Linux computer that brings extensibility in hardware and software adapting to your needs.

The Comet runs on Mechanix OS based on Debian, which means all 60,000+ packages in the Debian repos work out of the box.

Plus, you are free to port any distro you like. The Mechanix Shell is built in rust and supports GPU rendering on Wayland.

One of my main gripes with #LinuxOnMobile has always been On-Screen Keyboards. phosh-osk-stub finally seems to do everything I want. It autocompletes words and has keyboard layouts that don't force you to switch through too many pages, offering long-presses instead.

@furilabs plans to enable it on the #FLX1 by default. To enable it in the meantime:

1. sudo apt-get install phosh-osk-stub
2. sudo update-alternatives --config Phosh-OSK
3. Choose option "2"
4. Reboot
