Bare-Metal Kubernetes, Part I: Talos on Hetzner
I’ve been running a Kubernetes cluster on a mix of virtual and bare metal machines with Hetzner for about a year now, and while the setup has served me well, being a very exploratory exercise at the time it wasn’t very well documented.

Kubernetes Needs an LTS
There is no denying that containers have taken over the mindset of most modern teams. With containers, comes the need to have orchestration to run those containers and currently there is no real alternative to Kubernetes. Love it or hate it, it has become the standard platform we have largely

I don't need a VPS anymore
I've paid for either a "shared hosting" subscription, or a VPS subscription, for my own use, for the last two decades. Mainly for serving web traffic, but also for backups, for Git repos, and for other bits and pieces.

Could we stop Yellowstone from erupting with a giant geothermal power plant?
It’s become fairly common knowledge that Yellowstone National Park, in addition to being incredibly beautiful, is sitting on top of an enormous supervolcano that catastrophically erupts every few hundred thousand years.

Scaling Mastodon in the face of an exodus
TL;DR: Mastodon’s Sidekiq deferred execution jobs are the limiting factor for scaling federated traffic in a single-server or small cluster deployment. Sidekiq performance scales poorly under a single process model, and can be limited by database performance in a deployment of the default Dockerized configuration.

Golang SSH Redux
I’ll cover the post/blog, and then I’d like to counter some misconceptions. While part of me thinks “I must’ve been very unclear to have so many people misunderstand”, I also saw how many people commented without bothering to read, so really there’s a limit to how much self-flagellation will happen.

Modern CI is too complex and misdirected (2021)
The state of CI platforms is much stronger than it was just a few years ago. Overall, this is a good thing: access to powerful CI platforms enables software developers and companies to ship more reliable software more frequently, which benefits its users/customers. Centralized CI platforms like GitHub Actions, GitLab…

Caddy compatibility for zeroserve: 3x throughput and 70% lower latency
zeroserve is a high-performance HTTPS server that runs eBPF scripts in userspace ( intro ). Now it's got a Caddy-compat mode - when provided a Caddyfile, zeroserve JIT-compiles it to eBPF and then to native x86_64/ARM64 machine code, and runs it in an io_uring event loop.

Why Tarsnap doesn't use Glacier
On the surface, Tarsnap sounds like the perfect use case for Glacier. Out of every TB of data stored on Tarsnap, in any given month approximately 100 GB of data will be deleted, while only 33 GB of data will be downloaded; in other words, Tarsnap is very much a "write once, read maybe " storage system. Tarsnap's…

Apple Developer Center still down
It’s now been almost three full days. I don’t know anything about their infrastructure, but for a web service to be down this long with so little communication, most “maintenance” or migration theories become very unlikely.

Nginx: a caching, thumbnailing, reverse proxying image server
A month or two ago, I decided to remove Varnish from my site and replace it with Nginx's built-in caching system . I was already using Nginx to proxy to my Python sites, so getting rid of Varnish meant one less thing to fiddle with. I spent a few days reading up on how to configure Nginx's cache and overhauling the…

Why systemd is a problem for embedded Linux
I don’t want to post yet another anti-systemd rant, but I think the ubiquity of systemd could eventually create real problems for embedded Linux. I just wish I knew what to do about it.
