Reclaiming the lost art of Linux server administration
One of the skills I wish I’d learned earlier in my career is basic Linux server administration. Specifically in relation to hosting something on the web, either a web app or API that I wrote myself, or something from the thriving self-hosted community , such as WordPress.

The Curse of NixOS
I've used NixOS as the only OS on my laptop for around three years at this point. Installing it has felt sort of like a curse: on the one hand, it's so clearly the only operating system that actually gets how package management should be done. After using it, I can't go back to anything else. On the other hand, it's…

I got pwned by my cloud costs

Who Watches Watchmen? – Integrating Elixir Applications with Systemd
A lot of application use systems like Kubernetes for their deployment. In my humble opinion it is often overkill as system, that offers most of the stuff such thing provide, is already present in your OS. In this article I will try to present how to utilise the most popular system supervisor from Elixir applications.

On Web3 Infrastructure
In recent months, there has been a resurgence in the usage of the term “web3”: a nebulous term that (like it or hate it) has suddenly become a banner for much of the innovation happening in the space of blockchain and distributed ledger technology.

Self-Hosting Dozens of Web Applications and Services on a Single Server
Over the years, I've accumulated quite a collection of websites, web applications, APIs, and other services that I've built and continue to host publicly.

The Container Throttling Problem
This is an excerpt from an internal document David Mackey and I co-authored in April 2019. The document is excerpted since much of the original doc was about comparing possible approaches to increasing efficency at Twitter, which is mostly information that's meaningless outside of Twitter without a large amount of…
