Listening to the latest FLOSS Weekly podcast. @JP_Bennett and @randalschwartz talking open source legal matters. It sounds great as always.

A major project I've been working on for many months is rendering vector graphics strokes on GPU. @armansito and I recently wrote a paper on our techniques, and it's now available on arXiv (and also submitted to a relevant conference): https://arxiv.org/abs/2405.00127
There's accompanying code and some more resources in the repo: https://github.com/linebender/gpu-stroke-expansion-paper. And of course there's the implementation in Vello.
I'm very proud of this work. Fingers crossed the paper gets accepted.
Vector graphics includes both filled and stroked paths as the main primitives. While there are many techniques for rendering filled paths on GPU, stroked paths have proved more elusive. This paper presents a technique for performing stroke expansion, namely the generation of the outline representing the stroke of the given input path. Stroke expansion is a global problem, with challenging constraints on continuity and correctness. Nonetheless, we implement it using a fully parallel algorithm suitable for execution in a GPU compute shader, with minimal preprocessing. The output of our method can be either line or circular arc segments, both of which are well suited to GPU rendering, and the number of segments is minimal. We introduce several novel techniques, including an encoding of vector graphics primitives suitable for parallel processing, and an Euler spiral based method for computing approximations to parallel curves and evolutes.
A couple of days ago at work we announced the Steam Deck OLED. Itโs available next week (Nov 16) and though itโs got a bunch of great improvements like longer battery life, faster downloads, the star is the ultra-bright HDR OLED screen.
The screens are ridiculously bright and vibrant, so we thought it would be fun to use actual Steam Deck OLEDs as lighting sources to light our entire launch trailer.
Of course this necessitated building a giant metal orb. First though, hereโs the final spot:
PSA: Google has now begun to roll-out the Ad Topics "feature" onto Android itself. It's not just in Chrome you have to disable the settings. Please #Boost to spread awareness.
If you didn't get the pop-up screen on your Android device (it looks like the first two screenshots), to opt-out of these settings:
If you don't see "Ad Privacy" in Step 4 then it means that it hasn't been rolled out to you yet. You might need to wait and check back in a couple of days to see if/when it has been implemented to disable these settings.
EDIT: There's another setting to review. In step 2, scroll to "Personalize using shared data". Turn everything off.

Brian over at Twitter did a proof of concept port of 500,000 lines of code from Unity to Godot in a couple of days.
โThe rest is โjust workโ; though there is a substantial amount of work in the VFX/sound/UI rigging, the derisk is complete.โ
