Build Your Own FPGA (2012)
The Open 7400 Logic Competition is a crowd-sourced contest with a simple but broad criteria for entry: build something interesting out of discrete logic chips. It's now in its second year, and this time around I was inspired to enter it.

Build tools around workflows, not workflows around tools
While I was there, I thought a lot about tools – mechanical tools, software tools, tools that last, and tools that are fragile. The somber snow-covered scenery made me think about how quickly most of the tools we use today get outdated or replaced, and I thought about the kinds of tools that I’ve been building for…

Parsing S-expressions in C (2019)

Can't you just right click?
In 2012, Apple added Gatekeeper to Mac OS X (now macOS). When you try to run Mac software downloaded from the internet, Gatekeeper checks whether the software was signed with a valid Developer ID certificate. If not, then Gatekeeper refuses to run the software. Over the years, Gatekeeper has become more strict…

Rust and C++ Interoperability in Chrome
Chrome engineers are experimenting with Rust. For the foreseeable future, C++ is the reigning monarch in our codebase, and any use of Rust will need to fit in with C++ — not the other way around. This seems to present some C++/ Rust interoperability challenges which nobody else has faced.

WebAssembly without the browser
Most WebAssembly tutorials and examples you will find online focus on using it inside the browser in order to accelerate various functionality of a website or web app. However, there is an area where WebAssembly is really powerful but not talked too much about: outside the browser usage scenarios. That is what we’ll…

Hiding messages in x86 binaries using semantic duals
This is a quick writeup of a steganographic tool that I threw together: steg86 . It uses a quirk of the x86 instruction encoding format to hide messages in pre-existing binaries with no size or performance overhead.
