I always wanted a simple way to put the phone to silent mode when e.g. placing it on the table next to the 🛏️ . Since Biemster got NFC to work on the Oneplus 6/6T (https://github.com/biemster/pmos-openbox-conky/blob/main/nxp_nci_i2c.py) we can leverage that and have feedbackd's profile adjusted when certain RFIDs are seen (https://source.puri.sm/Librem5/feedbackd/-/merge_requests/154). For this to land we want to move the NFC support from a python script to s.th. like nfcd (https://github.com/biemster/pmos-openbox-conky/pull/18#issuecomment-2653920089). Help on this would be appreciated.

I think some of the replies to this poll are missing the historical importance of wobbly windows and the technological advancements in the open source ecosystem that they represented. I feel privileged and grateful to have been present at the dawning of the wobbly window era.

Been recording some profiles to try to explain _why_ my Rust translations of C programs tend to default to being faster.

Here's an unexpected culprit: strlen/strcmp.

The "natural" string representation in C is a char* pointing to a buffer that ends in a NUL (ASCII 0). To determine its length you have to crawl along it to find the NUL. To compare two strings, you need to do the same. In particular, because strcmp's return value isn't just a flag, but an integer giving the lexicographic relationship between the two strings ... it can't early exit if the lengths differ.

The "natural" string representation in Rust is a &str, which combines a pointer and a length. Finding the length is a constant-time near-no-op; comparing two strings for equality can trivially early-exit.

This might sound trivial, but profiles suggest it's a significant factor in wartcl being 4x faster than partcl across the board. In part, I suspect a lot of C programs do a lot of redundant strlen-computation unintentionally.

The recording of "postmarketOS - what is it and what's new?" has been released!

Not in the video: three very nice people in the front immediately holding up their laptops as somebody in the audience asks about postmarketOS on other devices than phones 😀

Check out the other talks from the FOSS on Mobile Devices room too. I saw most of them and they were quite interesting!

Today there was a secret #mobian meetup 🌈

@dos @postmarketOS yes I presume OpenEZX might have been the first attempt at open source software for the application processor of a smartphone. At least I didnt know any other such project back then. It sadly never went very far, as several key contributors including I got "distracted" with doing #openmoko - but that was also a good thing, of course

Coming up next for #fluConf we have another article, this time by @agx

Flow –the animated sensation of the year– was created in Blender! Francesco had a chat with director Gints Zilbalodis to discuss his experience working on the film. The interview covers topics such as learning Blender, working with a team (actually multiple small teams), using add-ons, and single-handedly lighting and rendering the film. Enjoy: https://www.blender.org/user-stories/making-flow-an-interview-with-director-gints-zilbalodis/ #b3d

Really had an amazing day at #FOSDEM today. The #LinuxOnMobile stand was absolutely *heaving* all day (as were our neighbouring @postmarketOS and @calyxos stands) even after all the other stands had left.

So much interest in #AsteroidOS, #SailfishOS, #Mobian and @linmob So great to see so many new and familiar faces.

My only regret is that I didn't get to go to any talks. I'll have to set aside two weekends to watch all the videos!

If you're at #FOSDEM and interested in running #Linux on your phone or watch (you should be!) then swing by the #LinuxOnMobile stand on Saturday or Sunday in building K, stand K1-C-6! We'll have #AsteroidOS, #Mobian, #SailfishOS, the @jolla Mind2 and more to test out and try. @linmob will be there with stickers and insight. Plus @postmarketOS and @calyxos are right next door!
