Golang's big miss on memory arenas
When your software team needs to pick a language today, you typically weigh two factors: language performance and developer velocity.

C++ says “We have try... finally at home”
The destructor serves as the "finally".

A possible future of Python in the browser
My Python code was too slow, so I made it faster with Python. For some definition of “Python”.

My Ideal Array Language
The fundamental units of computation available to users today are not the same as they were 20 years ago. When users had at most a few cores on a single CPU, it made complete sense that every program was written with the assumption that it would only run on a single core.

A surprising enum size optimization in the Rust compiler
Enums are one of the most popular features in Rust. An enum is a type whose value is one of a specified set of variants.

Understanding Memory Management, Part 5: Fighting with Rust
This is the fifth post in my planned multipart series on memory management. You will probably want to go back and read Part I , which covers C, parts II and III , which cover C++, and part IV , which introduces Rust memory management. In part IV, we got through the basics of Rust memory management up through smart…

Recto – A Truly 2D Language
Recto is a 2D programming language that uses nested rectangles as its core syntax, encoding structure and recursion directly in space instead of a linear stream of text. Recto explores new ways to write, parse, and reason about code—and even natural language—spatially.

Writing your own C++ standard library from scratch
The C++ standard library (also know as the STL) is, without a doubt, an astounding piece of work. Its scope, performance and incredible back...

Go Data Structures (2009)
When explaining Go to new programmers, I've found that it often helps to explain what Go values look like in memory, to build the right intuition about which operations are expensive and which are not. This post is about basic types, structs, arrays, and slices.

I learned Snobol and then wrote a toy Forth
This page is a mini-site for my Snobol excursion with links to separate pages for my:

Garbage collection for Rust: The finalizer frontier
Abstract Rust is a non-Garbage Collected (GCed) language, but the lack of GC makes expressing data-structures that require shared ownership awkward, inefficient, or both. In this paper we explore a new design for, and implementation of, GC in Rust, called Alloy . Unlike previous approaches to GC in Rust, Alloy allows…

In Defense of Matlab Code
MATLAB still shines for math-heavy work. Its whiteboard-style syntax makes code easy to read, review, and run on modern tools like RunMat and fast GPUs.

An update on Dart macros and data serialization

Hard Mode Rust (2022)
This post is a case study of writing a Rust application using only minimal, artificially constrained API (eg, no dynamic memory allocation). It assumes a fair bit of familiarity with the language.

Layered Design in Go
This post will describe how I design my programs in Go. I needed this for work, and while I searched for a link, nothing quite fits my coding practices out there. The word “Layered” can pull up some fairly close descriptions, but I want to lay out what I do.

The forgotten meaning of "jerk"

The inevitability of the borrow checker
