Perhaps Anthropic should put a freeze on new signups until they can increase capacity. This is the best kind of problem for a business, I'm cheering for them.

Even with IDEs that have a terminal view, I still much prefer using a separate terminal app.

Careful, their ToS makes it clear they train on your Antigravity prompts (even on AI Ultra) and there is no opt-out that I can find.

Google keeps changing their privacy and “don’t train on my data/code” options. When gemini-cli launched, there was a clear toggle for “don’t train on my code.” That’s now gone; it just links to a generic privacy page for me. Maybe some

A v2.0 update for my biology education app. I'm adding the ability to walk around cell models with billions of atoms on the Vision Pro. I'm designing the content browser right now. I'm trying to achieve something really immer

It's becoming quite common in S Korea for there to be a fixed tablet on a stand at each table. You order from the digital menu and then immediately pay with the integrated PoS. If there's no tablet you pay on your way out. There&#

It's not beyond imagination that this will happen to the Canadian Prime Minister next.

Optimizing our rendering algorithms for Apple Vision Pro. Trying to render a 300-million atom cell model at 90fps stereo. It's trivial on a 4090, it's pretty hard on a ~30W mobile GPU (W correct??). I'm thinking about a bunch

Thank you for the gentler perspective, and I do think it plays a role.

In my university days I climbed Mt Fuji at night for the sunrise in jeans, running shoes and a little tiny pen light. At the top there were people with small oxygen tanks (understandable, there are legitimate medical concerns for some). I&#

"Current visualization software, such as UCSF ChimeraX6, can only render one or a few protein structures at the atomic level." Lots of current visualization software is focused on visualizing a single protein structure (for exampl

I just released a biology education app very much like the preprint for the Vision Pro launch (and soon for iPad/iPhone). I worked with David Goodsell's group to integrate their whole-cell bacteria model and David wrote the conten

I can feel my ears tense when those "pings" go off (on the AirPods Pro and AirPods Max). This can't be healthy.

Apple engineers reading this: The painfully loud "PING" sounds on the AirPods Max hurt my ears when I switch from transparency to sound isolation mode. It's really unpleasant and I'm concerned this is damaging my hearing

I share your enthusiasm for C++ interoperability. I'm a computer graphics researcher and I have written my share of C++. I'm using Swift on my current project and there are a wealth of C++ geometry and numerical libraries that I w

I'm excited about a few projects bringing Swift to other platforms. SwiftWasm is surprisingly painless to get working [1]. Tokamak is an early stage SwiftUI-compatible framework for building web apps [2]. It also has the goal of suppor

Is it my imagination or has Apple been quietly improving and expanding the documentation for SwiftUI over the last few months? It's becoming decent, though there are still dark corners. Apple used to be awesome at documentation. I hope

I love the interactivity in your workshop sandbox. Is the bottleneck your Boid.findNeighbours function? (that was the first thing I tried on the GPU, except GPU parallelism let's us get away with 50,000 boids).

Sorry, I didn't mean to mislead you. This has little to do with Unreal (or Unity) and everything to do with GPU programming.

Wow. There are some great ideas in that paper.

You are right, they move insanely fast. The average speed of a medium-sized protein is about 5 m/s. Inside an E. coli, any two proteins will encounter each other at least once a second [0] (this book is incredible). My simulation is in

by timtimmy 6y ago
That's a cool idea. Imagine creating a little assembly line out of vesicles, each producing its own proteins, and feeding into each other. I like it.

I find Affinity Designer is way way faster to use than Illustrator. It's not just the rendering, the whole UI is streamlined. However, it's missing many features compared to Illustrator, especially some of the stroke patterns.

Boids are my favourite hello world for 3D simulation environments. For the last few weeks, I've been using boids to update my GPU programming skills and knowledge of related algorithms in Unity and Unreal. Yesterday I got 0.5 million b

It could be humidity. It’s very dry when it’s cold outside, heater kicks on, and indoor humidity plunges even further. The colder it is outside, the larger the differential to indoor humidity.
