My Favorite Rust Function Signature
I’ve gotten really into writing parsers lately, and Rust has turned out to be the perfect language for that. In the course of my adventures, I came up with the following:

Python's Innards: Introduction (2010)
A friend once said to me: You know, to some people, C is just a bunch of macros that expand to assembly . It’s been years ago (smartasses: it was also before llvm , ok?), but the sentence stuck with me. Do Kernighan and Ritchie really look at a C program and see assembly code? Does Tim Berners-Lee surf the Web any…

Which Parsing Approach?
We all know that parsing is an important part of designing and implementing programming languages, but it’s the equivalent of Brussels sprouts: good for the diet, but a taste that only a select few enjoy. Unfortunately, I’ve come to realise that our general distaste for parsing is problematic. While many of us think…

Emacs Prelude 1.0
I’ve got a big news to share with you today - after (over) 9 years of development, Emacs Prelude finally made it to version 1.0! There’s nothing really big or groundbreaking there, as Prelude has been in a pretty good place for a very long time feature-wise, but I felt like tagging a 1.0 release, because it’s 2020 and…

The compositor is evil
First, I want to make it clear that I’m not accusing the compositor of true evil, which I define roughly as deliberately causing suffering. There’s unfortunately too much of that in the world. I mean it in the more metaphorical sense that it causes serious problems and forces other parts of the system to be more…

From Rust to TypeScript
I was introduced to Rust in 2018 and has been enamored since. Rust is a system programming language, much like C++. Unlike C++ though, being relatively new, its language design is more modern and sophisticated. Writing with can feel more like writing TypeScript or Haskell. Not surprising since, despite being a…

Staff archetypes
Most career ladders define a single, uniform set of expectations for Staff engineers operating within the company. Everyone benefits from clear role expectations, but career ladders are a tool that applies better against populations than people. This is particularly true for Staff-plus engineers, whose career ladders…

I don’t have time for coding challenges
It tends to be standard recruitment practice in the tech industry to require candidates to complete some sort of coding test or challenge. Sometimes this takes the form of the much-feared whiteboard interview – where candidates are expected to work through a problem on the aforementioned whiteboard, in front of an…

The lack of namespaces on crates.io is a feature
Rust doesn’t have namespaces in its package management system. It’s often viewed as a bug. But it’s not a bug, it’s a feature! While there are negative aspects of a flat package registry, there are also real benefits. Stability, continuity, and unity (discourages forks and fragmented identity)…

What Clojure Spec is and what you can do with it

Decision Table Patterns
Decision tables are easy, simple, and powerful. You can teach them in five minutes and write one in half that time. You can look at a table and understand what it’s saying, see if it matches your problem, and check for design flaws. So it’s kinda weird that there’s basically nothing about them online. I wrote an…

Go modules have a v2+ problem
Go has a problem. Go modules place a strange naming requirement on modules version 2 or greater. Module names on modules v2+ must end in the major version ala …/v2 , and communication of this rule has been weak. It's non-obvious, and the community at large does not understand it.
