Flipping the bozo bit on flips the learning off – Surfing Complexity

Our tendency to focus on differences between us and them when the incident happens to them leads us to miss aspects of the system that we actually have in common with them. By focusing on the differences, we miss the opportunity to learn from their experiences, because it seduces us into believing there’s nothing for us to learn here.

Dear friend, you have built a Kubernetes

This is me every time 37signals announces new features in kamal.

Rearchitecting: Redis to SQLite

The SQLite hype train continues. Love to be Excited About Benchmarks.

The Balkanized Internet: Role of Big Cloud Providers

I am disabling AWS access to my on-prem servers (at least mostly). This is partly an experiment and partly an expediency, as I will explain. (As a technical side note, I’m mostly concerned with TCP traffic and it is possible to distinguish which is the client and which is the server from the initial handshake. I’m blocking connection attempts to my services from clients in AWS. Clients on my network can still establish connections to services hosted in AWS.)

Building a bare-metal Kubernetes cluster on Raspberry Pi

This is another Raspberry Pi cluster writeup that I sometimes read mournfully and wish I had the time & resources to do this myself.

Let's Build a 28-core Raspberry Pi Cluster!

Raspberry Pi clusters are one of my weird little obsessions. Want to start gathering up some of the examples I’ve seen, so here’s the one.

Copying files to a volume on Fly.io

Nice one Richard, really useful write-up. Helped me do my first restore-from-backup practice run for 666a.

Optimizing SQLite for servers

Will always bookmark a SQLite in production post. Learned something I didn’t love in this one!

Dead air on the incident call

Love anything about incident response. Fun post.

What if everybody did everything right?

Follow-ups on incidents are one of my fav topics and this is a very cool alternative perspective to bring to them.

LinuxCzar: My Philosophy On Alerting

Fantastic post. Alerting is such a delicate balance. You start to involuntarily develop Opinions about it once you’ve been paged in the night a few times due to some bullshit like Googlebot indexing the site and tipping CPU usage just above the alerting threshold. Or for downtime on an unimportant page that could realistically have stayed down until morning without consequence.

SQLite & Rails in Production

One of the articles that helped me get 666a up and running using SQLite.
