I used to be a frequent game jam attender. At game jams, you come up with a game idea and implement it from scratch, all within (usually) 48 hours. You can imagine that the resulting code tends not to be particularly beautiful; what matters is how it works when presented at the end of the jam. Did it crash on stage? No? Excellent!

Whenever I dig into the code of out-of-tree vendor-provided kernel drivers I keep wondering whether they were developed in a similar fashion 🤔

@Phaserune Read the post again ;)

@GregorDeBalzac Never really used Android nor iOS as my main device so it's hard to compare, but I've been daily driving Librem 5 for a good while now. There are still some annoyances, but nothing really showstopping - it works for me, on my terms, under my control. I can perceive it as a personal computer in mobile form factor rather than some vendor's appliance I'm merely operating, and I find it hard to settle for less once you get used to it.

Turns out that "should last years" was a bit too optimistic - it does last about a single year though in practice, which is good enough :)

@zwarf @mobian Yeah, https://salsa.debian.org/Mobian-team/devices/librem5-tweaks/-/commit/3ba470f85fbb56c7224da89b4265bbe560eb3953 should be removed. MM patch that lets it work has been merged upstream almost a year ago, so I imagine it already made it to the release used by Mobian.

@zwarf @mobian > The modem wakes up much slower for incoming phone calls while in suspend

Missing --test-quick-suspend-resume in ModemManager's args?

@nical GPU. Heavy shaders, lots of overdraw, cache and tile unfriendliness, jumping between pipelines back and forth... plenty of low hanging fruits (at least purely from the GPU perspective).

It used to spend the vast majority of frame time rendering a window shadow across the whole surface that was then promptly almost entirely obscured by the window itself 😁 It was particularly bad on phones, but could even be felt on Intel iGPUs with 4K screens.

@nical GSK has always been and still is so inefficient it just hurts to look at in RenderDoc; it's especially noticeable on mobile. Not complaining - it's doing well given the available resources - but if only some company actually invested dev hours into its performance it could do real wonders and make a huge difference.

@pecet@pol.social Allegro 5.2.9.1 śmiga bez problemu 😎

@mobian It is lens-specific and there is a database commonly used by image processing applications to apply such corrections (lensfun). This photo isn't a very great specimen for calibration, but it should be enough to let me learn how to do it 😜

@cnx Yup, cranked it up to eleven to not distract from the point with vignetting 😛

That's how straight lines look like through your phone's camera lens. Such distortion needs to be corrected in software. #shotonlibrem5
