Last year I wrote a year-in-review for my twenty-third birthday. And now it's time for another! In the last year, I have: visited Chiang Mai - Here for my birthday last year, until just after NYD. Came back here during summer to regain fitness

I've been using GitHub Actions more and more across the projects I maintain. It's a great offering and integrates well into GitHub. There are a few Rust projects I have where I wanted to automate the publishing of prebuilt binaries to the GitHub releases

If you read my blog or follow me on Twitter you may have noticed I'm a huge fan of flamegraphs. I've previously written about how I use them to profile PHP and Node.js applications, and I help maintain rbspy, a Rust profiler for

I was recently setting up some CI on GitHub Actions and ran across double builds for pull requests. The official documentation is still a bit lacking and it's a problem because it burns 2x the credits. In the end, I made this diff: -on:

Last October I made Upgrade your PHP, a site to let people know that PHP 5.6 and PHP 7.0 were about to reach their End of Life, and would no longer be officially supported. In the time since, I've been helping people

This post is a case study of how I profiled a Node.js application, and how using flamegraphs allowed me to make the boot time of Ghost 20% faster. I remember trying to profile Node.js many years ago and it was much harder

I always recommend to my clients that they use a CDN on their website. These are my recommendations for people using the Cloudflare Free plan, along with some warnings to watch out for. DNSStatus: Orange Cloud - this will ensure the requests go through

Earlier today I was looking at a couple of sites to see why they were much slower than I expected. I ran them through GTmetrix and saw the following in the waterfall tab. Straightaway I could see that this is the classic pattern produced

I recently added support for Ruby 2.5.4, 2.5.5 and 2.6.0-2.6.3 to rbspy, the sampling profiler written in Rust. I have replaced the original Flamegraph library by Brendan Gregg with Inferno, a Rust port. I also updated

I work with clients to improve the performance of their website. So - what benefits do I offer to them? 1. More timeServer maintenance and website optimization are important but time-consuming processes. They are often ignored in order to prioritise other activities but are

Last year I finished as a sole trader and set up a limited company. It was something I had been meaning to do for a while but it would incur several complexities that I was not ready for at the time. When business picked

By default, Cloudflare does not cache static HTML. It's nice when you're constantly pushing updates because the changes are immediately shown. But it does mean that you still have that short delay whilst Cloudflare gets the latest version of your page. If you have

A week or so ago, I saw the inferno project mentioned on the Rust subreddit. It was a rewrite of the great FlameGraph library into Rust. All of the work was being livestreamed by Jon Gjengset. I ended up watching some of the livestreams
