A practical introduction to WebGPU, WGSL, render pipelines, compute shaders, and the future of high-performance graphics on the web. Your browser can stream 4K video, run a complete code editor, render complex 3D scenes, and host multiplayer games. But for years, web developers accessed the GPU through an API based on an older generation of graphics programming. WebGPU changes that contract. WebGPU is not simply a faster version of WebGL. It is a new approach to graphics and parallel computation on the web—one built around explicit pipelines, modern GPU architecture, compute shaders, predictable resource management, and a shader language designed specifically for the browser. This article expands on the progression presented in the uploaded High Performance Graphics: Introduction to WebGPU material: why WebGPU matters, how it differs from WebGL, how WGSL works, how the rendering pipeline is constructed, and how compute shaders extend the GPU beyond graphics. WebGPU is not WebGL 3.0 This is the first mental model to correct. WebGPU does not build on WebGL. WebGL exposes a browser-friendly version of the OpenGL ES programming model. WebGPU instead uses concepts associated with modern GPU APIs and provides a portable abstraction over the graphics capabilities available on the user’s system. WebGPU and WGSL are W3C standards for accessing GPU acceleration from web applications. The API supports both graphics rendering and general-purpose parallel computation. ( W3C ) WebGL │ └── OpenGL ES-style state machine WebGPU │ ├── Explicit pipelines ├── Explicit resource bindings ├── Command encoding ├── Compute shaders └── Modern GPU execution model The difference is architectural, not cosmetic. In WebGL, you frequently change global rendering state and then issue a draw call. In WebGPU, you describe the pipeline and resources more explicitly, record commands, and submit those commands to the GPU. WebGL mental model Change state ↓ Change more state ↓ Bind resources ↓ Draw WebGPU
We consulted preparedness experts and WIRED’s team of testers for the essential gear to keep on hand in case of wildfires, earthquakes, and lord knows what else.
A new technical analysis published by the Cloud Native Computing Foundation (CNCF) argues that the future of agentic AI will be built not on entirely new infrastructure, but on the mature cloud-native ecosystem that already powers modern distributed applications By Craig Risi

FCC chair has been gifted at least $63,000 worth of tickets by CBS or its parent company.
Really interesting piece of cryptographic history : In November 2023, a large cache of his wartime papers—nicknamed the “Bayley papers”—was auctioned in London for almost half a million U.S. dollars. The previously unknown cache contains many sheets in Turing’s own handwriting, telling of his top-secret “Delilah” engineering project from 1943 to 1945. Delilah was Turing’s portable voice-encryption system, named after the biblical deceiver of men. There is also material written by Bayley, often in the form of notes he took while Turing was speaking. It is thanks to Bayley that the papers survived: He kept them until he died in 2020, 66 years after Turing passed away...

Great for indie darlings, but Sony, Microsoft, and Nintendo remain kings of TV gaming.
I receive an AWS Budgets alert that my budget is exceeding the alert threshold. Threshold is 5$. Forecasted amount is listed as $3,005,575,870.47. (Yepp, right, that’s 3 billion dollars.) I haven't even used AWS actively in the last year, but AWS console lists the amount as stated above. No feedback from AWS support yet, but the support AI chat bot says: "Die perfekt gleichmäßigen Tageskosten seit dem 1. Juli deuten stark auf einen Abrechnungs- oder Messfehler hin." ("The perfectly consistent da
From the best air fryer to frying pans to knife sharpeners anyone can use, these ideas will keep the curious home chef in your life tinkering away.
The Japanese Microwave measures food temperature directly, and stops cooking when food’s hot. It’s kinda terrific.
Nice PlayStation you got. Bet it could probably run Linux too.
I wanted to make this post because man...tables are way harder than they look. I documented my 1 year journey of optimizations on a stupid table for my Database GUI. I made everything from scratch like an idiot thinking it'd be easy but oh boy was I wrong... The article goes over all the optimizations I made to make my table render data smoothly without lagging. It goes from what data structures I used and the rendering optimizations I did. I used MongoDB Compass as a baseline since they use AG-Grid for their table and I'm pretty happy that my table feels way smoother than that (In my own testing)! But yeah, I never realized that there would be so much depth in making a performant table. PS. I decided not to use AG-Grid because there were a lot of customizations that I needed to do. I wanted column expansions ( if a field as an object or an array it would open columns to the right of it ). I also wanted an embedded text search where you could search for text within non visible columns (because they were in objects or arrays ) and AG Grid didn't really support that behavior so ..yeah. Anyways have a good read! submitted by /u/Fun-Chicken6946 [link] [留言]
