During that time I’ve used it for a few main usecases: A Search Engine, An APM Solution (after NewRelic started being stupidly expensive), a backend for Jaeger, and as a log storage system. In all of those usecases I’ve really pushed ElasticSearch to…

It was fun, and interesting, but ultimately the performance of the Compute Module 3+ it was designed around led me to running my homelab off some newer Pi 4 model B computers, which are at least twice as fast for almost…
A theory that cloud vendors will focus on the lowest layer of the infrastructure stack and startups will take over the software layer.
I maintain a VPS which I use to self-host a variety of services that I use: Joplin Server, Seafile , as well as for hosting websites that I develop. For the past few years, that VPS has been managed with Docker Compose, but recently I decided to build something a bit bigger. My goals with the project:
Exploring the tradeoffs of building container images at scale
The internet nowadays is ephemeral. Layers upon layers of trusted 3rd parties are necessary to distribute content online. It requires ongoing maintenance and is susceptible to censorship or hostile takedowns. In this blog post, I describe the steps I took to host my blog in a trustless, permanent, and…

A few months ago I moved to a few acres in the country, and needed somewhere to work - so I built myself a solar powered off grid office out of a Tuff-Shed Pro Studio! On one side, I’ve built a great desk corner with plenty of power and more than enough AC to keep me cool when it’s over 100F out.
