This is the story of the time I wrote some code, deployed it to production, and ended up bricking the server it was running on by frying the kernel. Beautiful rendition of me frying the kernel This post is about perils of concurrency and...
Unexpected performance deviations depending on how you spell zero.
Introduction The other day I was reading this blog post covering existential types in Rust (also known as impl Trait or opaque types). In that blog post, the author makes the following claim. We’re going to have to take a slight diversion into type theory here because it motivates a result that is perhaps intuitive…
You have probably heard a few talks or read a few articles where test driven development is depicted as a magic unicorn that watches over your software and makes everybody happy. Well, about 18.000 lines of "magic unicorn" code later, I'd like to put things into perspective.

If you’re familiar with nearly any mainstream programming language, and I asked you to draw a diagram of an array, the array indices, and the array elements, odds are good you’d produce a diagram something like this: In this post, I want to persuade you to replace that image, or, at least, to augment it with an…
Linked lists look harmless until they start detonating your game at runtime. This is the bug pattern far too many programmers miss.
This technology is already changing the creative industry. Here's how it works.
As noted in ASDL Implementation and Use Cases , I began with a simple AST interpreter for OSH, thinking that the two languages could share the same AST.
Click the table of zeroes once. Note that the text input field remains responsive even as we run 100,000 updates on the DOM. The colors of the table show the render batching boundaries. Note, I would not try this on a mobile device ;)
I started reading Joshua Bloch's Effective Java last week. I'll have to admit that I haven't read it before, but only because I've been told...
As someone who has from time to time written on parsing, and even published some parsing research , I get asked questions about parsing fairly regularly, some of which I’m even capable of answering.
One of my side-projects this summer is to become minimally literate in assembly language. So I began by reading up a tutorial on the x86-64 and the Linux ABI .
There is a pretty good comment on Hacker News (of all places) by nostrademons explaining why the DOM is not slow . Basically, all the DOM mutation operations are pretty trivial. Inserting and removing nodes, moving them around, setting an attribute, etc. It’s layout that takes a while and layout can be synchronously…
Then come along! Let’s make a compiler that goes all the way from source to assembly from scratch—no shortcuts!
Setting up PostgreSQL for tests is crucial for achieving performance and reliability. In this article, I'll explain how to set up PostgreSQL for tests and discuss some common pitfalls to avoid.
One of the most annoying problems in Swift is when the compiler gives an 'Expression was too complex to be solved in a reasonable time' error. I look at why this error occurs, how to avoid it and talk about how this should be solved in a future compiler update.
An obscure research project could radically accelerate innovation in programming language design
It’s terribly punny/dorky of me, but reading your post it just occurred to me one could start a blog called “Race Condition” about being a person of color and being a computer scientist.
Every year or so, something compels me to start over with a fresh OS image. Most recently, that something was an unfortunate water bottle incident. Once again, I need to pull down my digital life from the internet. The code and assets for this blog currently live in a 500 MB Git repository, which was hosted on…
What better thing to do, during the hot, hot July days, thank something semi-mechanical involving very little brain power? With student-facing work briefly calming down (we've just about weathered the storm of appeals and complaints following the publication of exam results), and the all-too-brief Summer holidays…

The measure of a modern software engineer in our attention economy is easily calculable thanks to companies like Microsoft acting both as bastion and companion in demonstrating one's prowess.
