Reflections on Software Performance
At this point in my career, I’ve worked on at least three projects where performance was a defining characteristic: Livegrep, Taktician, and Sorbet (I discussed sorbet in particular last time, and livegrep in an earlier post). I’ve also done a lot of other performance work on the tools I use, some of which ended up on…

Why Aren’t More Users More Happy With Our VMs? Part 1 (2018)
Programming language performance is something that nearly everyone cares about at some point, whether they realise it or not. If you’re a programmer, you sometimes have to make your programs run fast; if you’re a user, you might be frustrated at a program that runs slowly, without knowing that it’s caused by a poor…

How to Write a Book in Emacs (2015)
Writing a book is a time consuming process, and if you’re going to dedicate a year, or more, of your life to it, it makes sense to pick the best tool for the job. If you’re technically inclined – and if you use Emacs – then the choice is obvious.

Timeouts and cancellation for humans (2018)
Your code might be perfect and never fail, but unfortunately the outside world is less reliable. Sometimes, other people's programs crash or freeze. Networks go down; printers catch on fire . Your code needs to be prepared for this: every time you read from the network, attempt to acquire an inter-process lock, or…

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…

Types as axioms, or: playing god with static types
A common perspective is that types are restrictions . Static types restrict the set of values a variable may contain, capturing some subset of the space of “all possible values.” Under this worldview, a typechecker is sort of like an oracle, predicting which values will end up where when the program runs and making…

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)…

Graphtage: A New Semantic Diffing Tool
Graphtage is a command line utility and underlying library for semantically comparing and merging tree-like structures such as JSON, JSON5, XML, HTML, YAML, and TOML files. Its name is a portmanteau of “graph” and “graftage” (i.e., the horticultural practice of joining two trees together so they grow as one). Read on…
