Julia as a CLI Calculator
I have been using the Julia REPL as my day-to-day calculator on the command line for more than a year now. I am surprised that I haven’t seen more posts talking about how powerful and extensible the language is for simple numerical calculations and scripting In fact, the Julia REPL is much more than a simple…

From Stacks to Trees: A new aliasing model for Rust
Since last fall, Neven has been doing an internship to develop a new aliasing model for Rust: Tree Borrows. Hang on a second, I hear you say – doesn’t Rust already have an aliasing model? I...

I wrote a string type
I write compilers for fun. I can’t help it. Consequently, I also write a lot of parsers. In systems programming, it’s usually a good idea to try to share memory rather than reuse it, so as such my AST types tend to look like this.

Why not just do simple C++ RAII in C?
Ever since I finished publishing the “defer” paper and successfully defended it on its first go-around (it now has tentative approval to go to a Technical Specification, I just need to obtain the necessary written boilerplate to do so), an old criticism

My review of the C standard library in practice
In general, when working in C I avoid the standard library, libc, as much as possible. If possible I won’t even link it. For people not used to working and thinking this way, the typical response is confusion. Isn’t that like re-inventing the wheel? For me, libc is a wheel barely worth using — too many deficiencies in…

Both true and false: a Zen moment with C
I ran into a really fun bug at work yesterday, where I discovered that my C program was branching down logically inconsistent code paths. After drinking another cup of coffee and firing up GDB I realized that somehow, a boolean variable in my code was simultaneously testing as both true and not true.

My experience crafting an interpreter with Rust (2021)
Last year I finally decided to learn some Rust. The official book by Steve Klabnik and Carol Nichols is excellent, but even after reading it and working on some small code exercises, I felt that I needed more to really understand the language. I wanted to work on a small project to get some hands-on experience, but…

Curl removes experimental HTTP back end in Rust
The ride is coming to an end. The experiment is done. We tried, but we admit defeat. Four years ago we started adding support for an alternative HTTP backend in curl. It would use a library written in rust, called hyper. The idea was to introduce an alternative implementation of HTTP internals that you could ……

Asm.js AOT compilation and startup performance
With the recent announcement of a commercial game shipping using Emscripten and asm.js , I thought it’d be a good time to explain how asm.js is executed in Firefox and some of the load-time optimizations we’ve made since the initial landing of OdinMonkey in March. (OdinMonkey is an optimization module inside Mozilla’s…
