Last week, I launched a personal project . A nice change that most definitely came from a desire to do something else during covid-19 lockdown. With that launch came a desire to have some level of analytics, I didn't need the full customer journey but I sure was curious how many people were using my site after I…

I briefly describe each tool (pip, venv, pip-tools, pyenv, conda, pipenv, poetry and Docker), why it’s created and the problems it’s tackling. You can find a table summarizing all the information and the usual setups people use.
For a long time when I’ve wanted to test the latency of computers and UIs I’ve used the Is It Snappy app with my iPhone’s high speed camera to count frames between when I press a key and when the screen changes. However the problem with that is it takes a while to find the exact frames you want, which is annoying when…

In the first year, we shipped mid 8 figures per year worth of cost savings as a result. The key feature this system introduces is the ability to query metrics data across all hosts and all services and…

Initially I wanted to write articles on those two topics separately (mocking time and testing event loops), but during the process I realized that the things I want to talk about are too interrelated: when I need to mock time, it's usually to test some event loop with it, and when I test event loops, typically mocked…
As a computer engineer, my job is to use computers to solve important problems. Ideally my solutions will be efficient, and typically that means making the best use of the resources at hand. Quite often these resources are machines running Windows and, despite my misgivings about the platform, there is much to be…
I generally enjoy reading the uses this blog, and recently people have been talking about desk setups in my bubble (and on my Twitch stream), so I figured I’d write a post about my current setup!
I have a small collection of servers, laptops and desktops. My servers were purchased and configured at different times. By design, they have different hardware and software configurations. I have processors from AMD, Intel, Ampere and Rockchip. I have a wide range of Linux distributions, both old and new. I also…
