Why I'm leaving Elm
Over the past year or so, I've reluctantly come to the conclusion I need to leave Elm and migrate to some other language (most likely Bucklescript via philip2), and I definitely cannot recommend it to anyone else. This post is about my reasons for that, which are mostly about the way in which the leadership behave. I'm not going to talk about the good points of Elm as a technology. You can read th

Celebrating Over 10 Years Of Being Too Lazy To Pick A Tagline Title is literally true. This may not be the best place to learn about these concepts for the first time, because I'm going to focus on knocking down the misconceptions about them.

Implementing SLOs By Steven Thurgood and David Ferguson with Alex Hidalgo and Betsy Beyer Service level objectives (SLOs) specify a target level for the reliability of your service. Because SLOs are key to making data-driven decisions about reliability, they’re at the core of SRE practices. In many ways, this is the most important chapter in this book. Once you’re equipped with a few guidelines, s

Database Migrations
Table of Contents I consider database migrations one of the most annoying problems to deal with during a software engineer’s life. Not only that, if it goes wrong, as it often does, people tend to develop anxiety related to any schema changes. So why is it so annoying? It looks simple at first glance but is deceptively tricky when you start thinking about it. My primary framework of choice is the

Here’s a list of reasons why SELECT * is bad for SQL performance, assuming that your application doesn’t actually need all the columns. When I write production code, I explicitly specify the columns of interest in the select-list (projection), not only for performance reasons, but also for application reliability reasons. For example, will your application’s data processing code suddenly break whe

The Big Cloud Exit FAQ
Just over a year ago, we announced our intention to leave the cloud. We then shared our complete $3.2 million cloud budget for 2022, and the fact that we were going to build our own tooling rather than pay for overpriced enterprise service contracts. The mission was set! A month later, we placed an order for $600,000 worth of Dell servers to carry our exit, and did the math to conservatively estim

In recent years, it would appear that data engineering is converging with DevOps. Both have embraced cloud infrastructure, containerization, CI/CD, and GitOps to deliver reliable digital products to their customers. The convergence on a subset of tooling has led many to the opinion that there is no significant distinction between data engineering and software engineering. Consequently, the fact th

This simplifies the API while maintaining its structure. What is IndexedDB? I
Over the last few weeks I built my own DNS client. Mostly because I thought dig (the standard DNS client) was kinda clunky. Partly because I wanted to learn more about DNS. So here's how I built it, and how you can build your own too. It's a great weekend project, and I learned a lot from finishing it. Why? Julia Evans gave me the idea of making a DNS client. She's one of my favourite tech blogger

A Chrome feature is creating enormous load on global root DNS servers
The Chromium browser—open source, upstream parent to both Google Chrome and the new Microsoft Edge—is getting some serious negative attention for a well-intentioned feature that checks to see if a user's ISP is "hijacking" non-existent domain results. The Intranet Redirect Detector, which makes spurious queries for random "domains" statistically unlikely to exist, is responsible for roughly half o
