Rust and C++ on Floating-Point Intensive Code
I have developed some interest in the Rust programming language. Rust is a systems programming language which means it gets out of the way of developers interested in reaching low-level internals of a system. What sets it aside from other systems languages though is: Borrow checking to guarantee memory safety…

80x25
Every now and then, my brain clamps on to obscure trivia like this. It takes so much time. “Because the paper beds of banknote presses in 1860 were 14.5 inches by 16.5 inches, a movie industry cartel set a standard for theater projectors based on silent film, and two kilobytes is two kilobytes” is as far back as I…

Here’s Why Juicero’s Press is So Expensive
Hidden away in Juicero’s bad week of press is one of the most powerful lessons we preach to hardware startups: unconstrained development is lethal. Last week Bloomberg published an article exposing how easy it is to “hack” Juicero’s produce packs by squeezing them with your hands, deeming the $69

How to not rewrite it in Rust
Once you get past the growing pains of the Borrow Checker and realise Rust gives you the power to do things which would be unheard of (or just plain dangerous) in other languages, the temptation to Rewrite it in Rust can be quite strong. However at best, the temptation to RiiR is unproductive (unnecessary duplication…

We are leaving the Apple App Store and all its problems
For many years developers were not particularly satisfied with Apple's AppStore. It creates an artificial frontier between users and developers. Developer can not inform users about updates, tips, issues or fixes, and users often turn to the AppStore with one star reviews and negative comments instead of reaching out…

Geometry, Algebra, and Intuition (2017)
I have a confession to make: I have always found symbolic algebra more intuitive than geometric pictures. I think you’re supposed to feel the opposite way, and I greatly admire people who think and communicate in pictures, but for me, it’s usually a struggle.

An Introduction to Real-Time Subsurface Scattering
A little while ago I was doing some research into the state-of-the-art for approximating subsurface scattering effects in real-time (mainly for skin rendering), and I had taken a bunch of loose notes to help me keep all of the details straight. I thought it might be useful to turn those notes into a full blog post, in…
