One of the most common stumbling blocks I hear from developers trying WebGPU is "I'm loading a glTF file (or any model format), how do I not end up with a million render pipelines?" So I wrote way too many words about exactly that!

The WebXR AR Module spec just reached candidate recommendation (CR) status!
A spec transitioning to CR is mostly an administrative technicality, but it does further solidify the place of augmented reality content on the web!

Took the kids trick-or-treating last night and met up with a family who's son (3yo-ish?) loves to ring doorbells.
I have never seen a more pure manifestation of joy than watching this young doorbell enthusiast be let loose on his neighborhood on Halloween night.

If you have a Quest 2/Quest Pro, you can try out the mixed-reality WebXR experience I've been building with PHORIA & Lusion at spatialfusion.io
We set out to build an experience that fully leveraged passthrough & plane-tracking, and push what was possible in WebXR.

Needless to say, I wouldn't pay any amount to retain a checkmark. The fact that I have one at all is something of a fluke. I happened to ask for it in the one week when Twitter was really legitimately trying to open it up to everyone.

$20 a month for a blue check strikes me as an absurd amount for your average user, given what Twitter provides in return, and an enticingly low amount for a scammer that wants to project legitimacy.

Bind Groups are probably one of the hardest parts of WebGPU to wrap your head around, especially if you're used to WebGL's style of uniform setting.
To help onboard new developers, I've written a doc to explain bind group use and best practices:

Is your overhead slower than a super Mario bros 3 speed run?
Quote Tweet
The Mario game that can be beaten the fastest is Super Mario Bros. 3, which can be completed in 19 frames, or 0.316 seconds, by pressing buttons very quickly during startup to execute unintended code. Below is every frame from starting up the game to finishing it.

Just got off a plane, turned off airplane mode, and my phone promptly drowned in a tsunami of political fundraising emails and texts.
Almost makes me jealous of the UK getting no say in their new PM. Almost.

Going into work today and an allen wrench just fell off of me. I have no idea where it was on my person or how it got there. Just *clank* now there's an allen wrench at my feet.
I'm just going to assume I've discovered a latent superpower to spawn small bits of bent metal.

More seriously, I don't understand the motivations behind why a party in power would move for a General Election early? Especially if they're doing an awful job, seems like they would just not vote for one to keep their seats as long as possible?

Apple's love/hate relationship with USB-C continues to get weirder with each new product release.
Quote Tweet
This is one of the weirder things Apple has ever done. I’m assuming the iPad Pro doesn’t have a landscape camera because there isn’t room for it and charging components for the second-gen pencil in the same spot, but forcing regular iPad owners to do this is just bizarre.

Excellent thread. I do love me a good graphics breakdown. ESPECIALLY when it's about older games! (Last decade's high end console/PC techniques are this decade's mobile/VR/web techniques.)

Hey ! Found a bug in the new WebXR AR passthrough mode for you! You can repro it right now on immersive-web.github.io/webxr-samples/
Seems like it's relying on the page to clear the backbuffer in this particular scenario?

If you get stuck with "AR NOT FOUND", make sure you have a relatively recent OS, e.g >=43 iirc.
