When TypeScript first landed in public view in October 2012, the type annotations looked a bit funky. If you were a student of type theory, they would have been familiar; but most programmers wouldn’t have seen a type annotation like this before: var name: string; Given the popularity of putting type names before variable names, […]
Last October, I was asked why released of a legacy system were so hit and miss. There were a couple of reasons for the flaky releases, which I have summarised below. When you judge the quality of the metaphors, please bear in mind that these were invented off-the-cuff. Configuration The first reason releases were unreliable […]
After reading a discussion about whether having a dedicated Scrum Master is an effective way of running a team, I got to thinking about what I have experienced in the real world. This is an empirical point I’m about to make; I’ve worked with a good number of organisations, but not enough to get to […]

This is a little gold nugget that is coming in C# 8 – implicitly scoped using statements. On a simple level, it means that when you consume an IDisposable class your previously explicitly scoped using statements: using (var connection = GetConnection()) { // Use the connection, it will be disposed of at the end } […]
IntelliCode brings AI-assisted power-ups to your auto-completion. It has been in preview within Visual Studio for some time (you can read about Visual Studio IntelliCode here) – but it has now landed in Visual Studio Code, which is exceptionally handy if you’re a TypeScript programmer like me. So what is IntelliCode? It’s a simple VSCode […]
It is pretty common to want to hydrate a class from a JSON value obtained in a service. If you just parse the JSON you get the properties, but not the behaviours that you expect. As this is a reasonably common problem to solve, it is worthing doing it just once. The following function will […]
I have been working out how to create a TypeScript NotFunction type for a while, in response to a Stack Overflow question. With the arrival of conditional types, I think there may be a way. It’s not perfect – but it does work. The type works by taking all possible types and converting the type […]
