FreeBSD Jails for Fun and Profit (2020)
Docker has recently stormed into software development. While its concepts are powerful and valuable, similar tools have been used in systems for decades. FreeBSD’s jails in one of those tools which build upon even older chroot(2). To put it shortly, with these tools, you can make a safe environment separated from the…

IPMI
I am making steady progress towards moving the Computers Are Bad enterprise cloud to its new home, here in New Mexico. One of the steps in this process is, of course, purchasing a new server... the current Big Iron is getting rather old (probably about a decade!) and here in town I'll have the rack space for more…

You may not need Cloudflare Tunnel. Linux is fine
Cloudflare Tunnel is a cool little product Cloudflare offers to essentially give your computer a public IP address. Getting a packet from point A to point B is Linux's bread and butter. Why not just use it?

AWS Elasticsearch: a fundamentally-flawed offering
I'm currently working on a logging project that was initially implemented using AWS Elasticsearch. Having worked with large-scale mainline Elasticsearch clusters for several years, I'm absolutely stunned at how poor Amazon's implementation is and I can't fathom why they're unable to fix or at least improve it. I…

Quadlets might make me finally stop using docker-compose
Sure, docker-compose is great, but could we get similar functionality using just the tools that are built into CoreOS? Can we get automatic updates, too? Yes we can! 📦

The microservices cargo cult
Microservices are awesome. We know this because of all the success stories that are circulating lately. The news is full of such stories, of people taking large, monolithic codebases, breaking them up, adding HTTP APIs and enjoying all the benefits.

Ansible open-sources Ansible Tower with AWX
Ever since Red Hat acquired Ansible, I and many others have anticipated whether or when Ansible Tower would be open sourced. Ansible Tower is one of the nicest automation tools I've used... but since I haven't been on a project with the budget to support the Tower licensing fees, I have only used it for testing…

Alternatives to MinIO for single-node local S3
In late 2025 the company behind MinIO decided to abandon it to pursue other commercial interests. As well as upsetting a bunch of folk, it also put the cat amongst the pigeons of many software demos that relied on MinIO to emulate S3 storage locally, not to mention build pipelines that used it for validating S3…

Roll your own Ngrok with Nginx, Letsencrypt, and SSH reverse tunnelling
Ngrok is a fantastic tool for creating a secure tunnel from the public web to a machine behind NAT or a firewall. Sadly, it costs money and it’s proprietary. If you’re a developer, odds are that you’re already renting a server in the public cloud, so why not roll your own ngrok?
