Java 8’s new Optional type doesn't solve anything

Good Practices for Writing Rust Libraries
For a bit more than a year now, I've been interested in Rust , a programming language by Mozilla research that “runs blazingly fast, prevents nearly all segfaults, and guarantees thread safety.” It is as low-level as C or C++, has a nice type system (with generics and traits), a helpful compiler, and a…

LLVM Code Generation in HHVM
One of the most common questions we get about HHVM is why we don’t use LLVM for code generation. The primary reason has always been that while LLVM is great ...

Goodbye CoffeeScript, Hello TypeScript
Given the shortcomings of CoffeeScript, we investigated many alternatives, including ClojureScript, Babel, Elm, and PureScript. TypeScript stood out as a clear winner. Here's why.

Living with Microsoft C++ Compiler Bugs and Ambiguities
It’s no secret that the Microsoft Visual C++ compiler has lots of non-standard behaviors. What’s even more unfortunate is that those behaviors are subsequently used by different libraries. Ultimately,

Forgotten Language: Jorf could have been Python or Ruby (2005)
A long time ago, there was no Internet. Ok, there was an internet, but I lived outside of it. It was 1992 or 1993, and I only saw my first webpage and send my first email in 1995. And I was perhaps…

Writing Friendlier Clojure
I love the Clojure language, but I don’t think there’s any use pretending that the combination of expressiveness, power, and repl-driven development can result in some staggeringly dense code. Everyone that writes Clojure is guilty of this at one time or another; you start with the core of your function, evaluate it…

LALRPOP, an LR(1) parser generator for Rust
Around four years ago, when I had first decided to start at Mozilla research, I had planned to write an LR(1) parser generator. It seemed like a good way to get to know Rust. However, I found that newborns actually occupy somewhat more time than anticipated (read: I was lucky to squeeze in a shower), and hence that…

Running Rust on the Rumprun Unikernel
The Rust programming language has been able to run on bare-metal without the standard library for quite some while now. However, most Rust applications depend on the std crate, and therefore still need a full operating system to run.

Object-oriented techniques in C
Although the techniques described below won't be very popular nowadays (after all, why bother using C if we're going to write object-oriented code?), they are still quite relevant for embedded systems and other low-level things (kernel development, etc). For example, lots of Linux Kernel subsystems use similar…
