"The Art and Secrets of #Karambola" - a digital 92-page #artbook heavily illustrated with yet unpublished sketches, drawings, paintings and locations from the game - is now out!

Agata (@holypangolin) reveals her thoughts on the curious fruity characters’ personalities and backstories, as well as some difficult decisions she had to make during the design process.

The recording of my #FOSDEM talk - a dive into a bug in USB 2.0 and the problem of spontaneous modem resets that used to be experienced on the #Librem5 is now available to watch: https://fosdem.org/2024/schedule/event/fosdem-2024-3200-universal-serial-bug-a-tale-of-spontaneous-modem-resets/ #linuxmobile #mobilelinux #usb #fosdem24 #fosdem2024 #fossonmobile #mobile #linux

The newest game I've been working on, ODGŁOS, is finally available to play! A cute owl, the history of electronic music, shapeshifting snakes and intergalactic journeys inside the Polish Radio Experimental Studio - all in a stop-motion interactive story :) You'll need a browser, headphones and 30 minutes to spare. Have fun!

#Introduction time!
My name is dos; some call me Sebastian. I made dozens of small silly video #games and some slightly less small ones too. I'm one half of @holypangolin studio. Sometimes I pretend to be a musician, but don't get fooled. I'm also a living encyclopedia on a Polish rock band "Perfect". Trams are cooler than trains. The more caramel, the better. I've been using GNU/#Linux on #mobile phones for ages, which led me to work with @purism on the Librem 5. btw I use Arch, but I ❤️ Debian!

Me: So, dear GitHub container repository, I need a version of this image from May 2023.

GitHub: Here is the list of 55 tags "published about 2 years ago"!

That's all I can think of on the spot. Of course there's still the camera and GPU stuff, but these would need their own dedicated threads 😂 Feel free to hit me up if you want to hack on some of these things, I could likely offer some help and guidance.

iio-sensor-proxy still needs some work in order to be able to use the compass: https://gitlab.freedesktop.org/hadess/iio-sensor-proxy/-/merge_requests/316

There's also a hall sensor which needs to be exposed to the userspace in some appropriate way: https://source.puri.sm/Librem5/linux/-/merge_requests/638

We're still missing a way to control the notification LED while the phone is suspended. There's a lightweight Cortex-M4 core that can keep running in suspend and some proof-of-concepts have been made to utilize it in the past, but nothing has been properly integrated so far.

The audio codec has a quite powerful DSP that can perform frequency linearisation based on speaker's and microphone's impulse response - but it needs to be fed with configuration parameters.

Speaking of audio, since there are two microphones - one on the top and one of the bottom of the phone, they could be utilized for noise cancellation. Right now only the bottom one is used for calls.

The touchscreen supports a low-power mode in which it can recognize some predefined gestures. It could be used to wake up the phone by, for example, double tapping the screen. Right now it just gets its power shut down as soon as the screen is blanked.

The GNSS module has an internal flash that can be used to autonomously store traces, letting the phone suspend and save plenty of power. It can also wake the phone up with geofencing. Right now you need to configure it manually with NMEA commands though, as there's no high-level infra to use at all.

There's also AGNSS to speed fixes up. I wrote a script to generate almanac/ephemeris data, but you need to run it manually and it could be improved with SBAS and GLONASS: https://source.puri.sm/-/snippets/1207

The Librem 5 (and mobile GNU/Linux in general) has matured a lot over the years, but there are still some areas where the software stack is behind the hardware capabilities. Some of them are often talked about, such as camera quality or GPU (GLES3/Vulkan/OpenCL), but there are also lesser known ones in need of some plumbing and middleware infrastructure. Maybe you'll find something interesting to hack on there?

Interesting feature. I used socat on my phone and suddenly this guy appeared. #catsofmastodon #cats #caturday #shotonlibrem5
