that moment when the GPU execution times regression you've been chasing for a week is just some funny performance behavior due to printing a metric ton of text in the console 😬

I really want physicians to stop claiming a description of the symptom is a diagnosis. I mean "arthritis". Yeah, we already know that.

Watching The Verge’s super cut of Apple’s iPad event, my thoughts:

1. I, like, don’t understand why they made the neural engine 60x faster. Like, which iPad apps use the neural engine rather than the GPU? If I were the product designer, I would nix the ANE completely and use that die space for a better GPU (which apps actually use)

This is super fascinating. After reading it, I have a few thoughts:

• China clearly picked a different tradeoff than anyone else between international business concerns and national security concerns
• I wonder if their intentional obfuscation extends to the entire world map, or just China
• if it’s public info how to map to GCJ-02, then it’s not hard to map from GCJ-02
• therefore, If the goal is to hide stuff from foreign governments, it clearly is ineffective

So, like…

Are the protesters at Columbia in the tents harming anyone? Are the tents blocking people from going where they need to go? If not, I think Columbia should just leave them be.

Suspend the ones saying antisemitic things, yes, but if people just want to set up tents in the middle of a quad …. Go right ahead?

And if the students are asking you to divest yourself from companies making a profit from war … maybe that’s a good idea and actually do it???

Interesting article on a novel legal theory about Section 230.

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.

SSD stands for "solid state drive".

That makes no sense. What is being driven?
I know it's from hard drive,. or floppy drive, where a disk was being spun.

I haven't had coffee since Sunday.
Ask me anything.

The feature I most want from HLSL is malloc()

If you've ever found yourself missing the "good old days" of the #web, what is it that you miss? (Interpret "it" broadly: specific websites? types of activities? feelings? etc.) And approximately when were those good old days?

No wrong answers — I'm working on an article and wanted to get some outside thoughts.

Solar panels! Much excited for them to be wired up tomorrow.

Jet lag and food poisoning will flatten you.
Fortunately I have a 284h podcast queue.

Banging my head against the wall... #webgpu #wgsl

It seems that I am getting pos.x as the actual screen coordinate instead of [-1, 1] as demonstrated by:

@fragment fn fragmentMain(@builtin(position) pos: vec4f) -> @location(0) vec4f {
var color = vec4f(0);
if(pos.x > 100) {
color = vec4f(1,0,0,1);
}
return color;
}

Any idea?????

Just got back from some business travel in Europe. Nice to see USB-C charge ports showing up in hotel rooms and airport seating.

I just realized that Objective-C exceptions won't release objects alive on the stack, even when ARC is enabled, which ... really limits exceptions' usefulness

It seems like the only time any Objective-C code should ever throw an exception is when the only sensible thing the process could do is to immediately exit

An update of the classic amazing printer review on The Verge. This time with Gemini content!

Mind you, I bought a fancy colour HP laser printer the last time. And I have to say changing the toner was amazing: the little display panel had a how-to video for EACH colour cartridge swap. But the toner was almost as expensive as a monochrome Brother laser printer... Le sigh.

Went to Best Buy with my wife to get her a Chromebook to replace her (very) old laptop, where we met Sales Guy who:

• Stuck around giving "advice" after we said we were fine, thanks. 🙄
• Continued to explain Chromebooks to us after I pointed out that I work on the Chrome team. 😠
• Pointed to my wife and asked "Does your mom want this on her account?" 🤬

Downloading Google Dawn on Windows10 fails due to filename too long.. here is the filename ImageSampleProjDrefExplicitLod_CheckForLod0_SpvParserHandleTest_ImageCoordsTest_MakeCoordinateOperandsForImageAccess_0.spvasm.expected.ir.msl

Kind of insane if you ask me...
