Postcodes After a pretty practical previous post about records and collections, this post is less likely to give anyone ideas about how they might tackle a problem in their own project, and doesn't have any feature requests for Microsoft either. It's an area I've found really fun though. An introduction to postcodes in the UK ... Continue reading Election 2029: Postcodes

Unexpected inconsistency in records The other day, I was trying to figure out a bug in my code, and it turned out to be a misunderstanding on my part as to how C# records work. It's entirely possible that I'm the only one who expected them to work in the way that I did, but ... Continue reading Unexpected inconsistency in records

In my previous blog post I described some behaviour of C# record types which was unexpected to me, though entirely correct according to the documentation. This is a follow-up post to that one, so if you haven't read that one yet, please do so - I won't go over all the same ground. Is this ... Continue reading Records and the with' operator, redux

As I've written before, I'm leaning heavily into immutability in the election site code. Until September 2025 (it's taken a long time to get round to writing this blog post) that meant a combination of records, ImmutableList<T> and ImmutableDictionary<TKey, TValue>. In an ECMA C# standards meeting, however, Joseph Musser passed on some really valuable feedback ... Continue reading Changing Immutable Collections

On January 15th 2026, Robert Jenrick broke my election site. Okay, that's slightly hyperbolic. The site continued to operate, and it would be fairer to say that the actions of Kemi Badenoch and Robert Jenrick exposed a flaw in the data modelling in my site. For those readers who don't follow UK politics, two events ... Continue reading Election 2029: Models and Reality

I've now been through three approaches to load testing for the site, and I think I've settled on a solution for the medium term at least. This post explains what I'm trying to achieve, along with the pros and cons of what I've tried. Requirements For this particular site, I have four requirements: If the ...
