Julian Haeger's Blog

It's 2026, and there is a lot of discussion around how good coding agents are.

Play is accepted as having an important role in the development of problem-solving skills and resilience in children.

I've decided to add comments to this blog using Giscus, which uses github discussions (in this repository) to store comments.

The Problem I work in a system in which there are a few DynamoDb tables used widely across many of the services.

Forget About Organisation And Never Lose Anything Again The Problem I'm sure all but the most organised of us have at some time been in that situation where we cannot find something we need despite looking in all the "sensible" places for it, and often in…

My daily commute is a short drive, followed by around 35 minutes on a cheap noisy diesel train whose noise level varies from loud to very loud depending on the terrain as the throbbing engine hauls it up hills.

In the problem domain of the company I work at, we have the common situation where external data is fetched into our system on a schedule and a number jobs occur which perform processing on it and store the results.

This last week I've been using TypeScript to write a small service at work.

In this post I'd like to continue looking at patterns used within functional programming.

Elixir Recently I've been tending to think and build in Elixir.

The problem I wanted to move a site, this site in fact, from running on my raspberry pi at home to Digital Ocean so as not to have to keep tinkering with flaky dynamic dns issues, but I didn't want to use up an entire droplet for it.

There are many reasons that Github has become the primary place to host open source repositories and stolen the hearts of many of its users in the process.

I recently read an article which argued the case for code comments.

One of the key ideas behind executable specifications, is that they form a set of specifications which “bite back”.

There are a number of popular services which have some idea of publishing your location, either automatically or on demand, often called checking in.

On Tuesday night I attended a “Geekup” in Manchester.

This post is going to be a little off topic, but as I said in my opening post, I’ll occasionally be posting about various things that interest me.

The recent compromise of Sony’s PlayStation network has been getting a fair deal of coverage in the news, not least because of the escape of credit card details.

I’ve seen the opinion thrown out quite a few times in various forums such as StackOverflow answers and comments, that one way you can tell your improving as a developer is if you look back at code your wrote some time ago and find it ugly.

The intention of this blog is for it to primarily cover my thoughts on code, and how we write it, with the occasional detour into anything else that interests me.

I’m sure its a pretty universal response to any detailed discussion or meeting involving a whiteboard for at least one person involved to take a photo with their phone.

I’m another software developer who felt like starting a blog.
