Using unwrap() in Rust is okay
One day before Rust 1.0 was released, I published a blog post covering the fundamentals of error handling . A particularly important but small section buried in the middle of the article is named “ unwrapping isn’t evil ”. That section briefly described that, broadly speaking, using unwrap() is okay if it’s in…

Great Works in Programming Languages (2004)
In September, 2004, I posted a query to the Types list asking people to name the five most important papers ever written in the area of programming languages. This page collects the responses I received. (A few are missing because I am still tracking down bibliographic information.)

What about K?
k is a family of concise, fast vector-oriented languages designed by Arthur Whitney . Calling k a “family” is deliberate; there is no single definitive k, but instead a sequence of slightly incompatible versions. If you decide to stick with k, you’ll see mentions of k4 , k5 etc. Exactly what those numbers mean aren’t…

Why F# evangelism isn't working (2015)
If you skim this blog entry too quickly or just read the title, you might think I am someone who does not like F#. Nothing could be further from the truth. Over the last several months, I have become a big F# fan. It has become my preferred language for personal projects.

The borrow checker within
This post lays out a 4-part roadmap for the borrow checker that I call “the borrow checker within”. These changes are meant to help Rust become a better version of itself, enabling patterns of code which feel like they fit within Rust’s spirit , but run afoul of the letter of its law . I feel fairly comfortable with…

Zig; what I think after months of using it
Ah, Zig . I have a love-hate relationship with this one. A “new” (reading: appeared a couple years ago , already — yes, already ), language with high ambitions. Zig was made to run at low-level, with a simple design to solve many problems C has (macros, allocators, error handling, more powerful types like baked-in…

My tutorial and take on C++20 coroutines
Over the last 25 years, I’ve written a lot of event-driven code in C++. A typical example of event-driven code is registering a callback that gets invoked every time a socket has data to be read. Once you have read an entire message, possibly after many invocations, you parse the message and invoke another callback…

What causes Ruby memory bloat?
Ruby apps can use a lot of memory. But why? Various people in the community attribute it to memory fragmentation, and provide two “hacky” solutions. Dissatisfied by the current explanations and provided solutions, I set out on a journey to discover the deeper truth and to find better solutions.

An Experimental New Type Inference Scheme for Rust
While on vacation, I’ve been working on an alternate type inference scheme for rustc. (Actually, I got it 99% working on the plane, and have been slowly poking at it ever since.) This scheme simplifies the code of the type inferencer dramatically and (I think) helps to meet our intutions (as I will explain). It is…
