The simplicity of single-file Golang deployments
Deploy Go apps as single static binaries with systemd. No Docker, no npm, zero-downtime via socket activation. Modern complexity is often unnecessary.

AWS’s anti-competitive move hidden in plain sight
Folks have been making noises for a while that Amazon is anti-competitive in a variety of ways. I don’t disagree with the overall sentiment, but there’s one particular aspect of how AWS advantages its own offerings that I don’t see folks talking about–and strikes me as particularly egregious.

Switching to Fedora Silverblue
For the last 10 years or so, Arch Linux has been my Linux distribution of choice. The early years were a bit rough, and the process of moving to systemd wasn't without its challenges either, though the experience has improved dramatically since then. In spite of these improvements, certain issues persisted, such as…

Don't let event-driven architecture buzzwords fool you
I see a lot of new terms like Command-Event, Event-Based Compute, etc., presented around Event-Driven Architecture. Let me clear that up because there are no such things…

Firecracker internals: Inside the technology powering AWS Lambda (2021)
You are most likely familiar with AWS Lambda and Fargate — Amazon's serverless computing engines. At its nature, serverless computing introduces quite a challenging task requiring both tight security and great performance. For exactly that matter Amazon came up with its microVM solution called Firecracker .

From Go on EC2 to Fly.io
How I switched hosting my Go-based side projects from Amazon EC2 to Fly.io, significantly simplified deployment, and saved a bit of cash while I was at it.

We stand to save $7M over five years from our cloud exit
Since declaring our intention to leave the cloud in October, we've been busy at work making it so. After a brief detour down a blind alley with an enterprise Kubernetes provider, we found our stride building our own tools, and successfully moved the first small application out of the cloud a few weeks ago. Now our…

In Praise of Alpine and APK
Since the change of year, I’ve been using Alpine Linux on my main computing device (a new desktop PC that I assembled in December). These are some notes on in, some niceties and caveats.

Moving my PC into my rack in a 2U case
This week I finally moved my gaming/Linux PC into my little office rack—it's that 2U box above the UPS at the bottom: I remembered seeing Linus Tech Tips' 4U build in a video a couple years ago—but he has a full 42U rack in his basement. I don't have that much space—just 2U (technically 3U if I wanted) in my little…

Clog: Making a homegrown ClickHouse log for $20 a month
There was recently a discussion on Hacker News around application logging on a budget. At work I've been trying to keep things lean, not to the point of absurdity, but also not using a $100 or $1000/month setup, when a $10 one will suffice for now . We settled on a homegrown Clickhouse + PHP solution that has…

How to create portable Linux binaries
Creating application binaries for Linux that run on a wide range of distributions is a bit tricky, as different distributions ship different versions of various system libraries. These are usually backwards compatible, but not forwards compatible, so programs linked against older versions of the libraries also work…

Service mesh use cases (2020)
Service mesh is a blazing hot topic in software engineering right now and rightfully so. I think it’s extremely promising technology and I’d love to see it widely adopted (in cases where it truly makes sense). Yet it remains shrouded in mystery for many people and even those who are familiar with it have trouble…

On the joy of podman and auto-updates (2022)
podman provides an integrated auto-update mechanism, which I recently applied to all of my containers running on feldspaten. The mechanism is nice, but at first appears a bit counter-intuitive. In this post ’m trying to explain how you can use the mechanism and what to watch out for. I’ll start with the trap I think…

Crafting container images without Dockerfiles
Last month I have been developing a Rust tool to create container images from Conda environments, without going through Docker. It was a wild trip down the rabbit hole of OCI images, so I thought I’d share part of the adventure here. Enjoy! But why? If you are used to building container images, you might be asking…

Scalability is overrated
Startup founders like to think about scalability—and that’s usually a good thing. But overly focusing on scalability overlooks one of the biggest advantages that startups have over larger companies.

Hyperscale in your Homelab: The Compute Blade arrives
This is the Compute Blade, and I'm test driving it in a four-node cluster: I'm testing the Dev version, and @Merocle from Uptime Lab sent four Blades, a 3D-printed 4-bay case (a metal 1U rackmount enclosure is in the works), and two fan modules. He's been testing 40 of these in a rack at Jetbrains for months, and…

The UK is wasting a lot of wind power

Microservices are hard
Over the past years I attended hundreds of interviews. Many candidates proudly told tales on how they develop their projects with a microservice architecture. Often (I don’t want to say “always”, but from my memory I think it actually is “always”) it does not require many questions to see that they used a rocket…
