Speed of Rust vs. C
The run-time speed and memory usage of programs written in Rust should about the same as of programs written in C, but overall programming style of these languages is different enough that it's hard to generalize their speed. This is a summary of where they're the same, where C is faster, and where Rust is faster.

How some good corporate engineering blogs are written
I've been comparing notes with people who run corporate engineering blogs and one thing that I think is curious is that it's pretty common for my personal blog to get more traffic than the entire corp eng blog for a company with a nine to ten figure valuation and it's not uncommon for my blog to get an order of…

Why did I spend 1.5 months creating a Gameboy emulator? (2017)
For me, the most favorite type of a computer program is an emulator. Being able to run code from a completely different hardware architecture always seemed like a magic.

Your hex editor should color-code bytes
every time i do, i feel bad for the poor person having to use it (especially if that person is me!). a plain list of bytes makes it hard to notice interesting things in the data. go ahead, try to find the single c0 in these bytes:

Reports of code's death are greatly exaggerated
There is a profound tension here: english specifications intuitively feel precise until you learn better from bitter experience. (It's all in that facial expression of the last frame.)

Rust After the Honeymoon
Two years ago, I had a blog entry describing falling in love with Rust . Of course, a relationship with a technology is like any other relationship: as novelty and infatuation wears off, it can get on a longer term (and often more realistic and subdued) footing – or it can begin to fray. So well one might ask: how is…
