On SQS
In my position I probably shouldn’t have a favorite AWS product, just like you shouldn’t have a favorite child. I do have a fave service but fortunately I’m not an (even partial) parent; so let’s hope that’s OK. I’m talking about Amazon Simple Queue Service , which nobody ever calls by its full name.

Containers, microservices, and service meshes
There is a lot of material out there about services meshes, and this is another one. Yay! But why? Because I would like to give you the perspective of someone who wish service meshes did exist 10 years ago, long before the rise of container platforms like Docker and Kubernetes. I’m not claiming that this perspective…

Building a home NAS on a shoestring budget with the Rock64 SBC (2018)
I’ve gone through many iterations of a Home NAS over the years. It started with an AMD Phenom based system running in a Norco case with about 8 hard SATA hard drives (4 primary, 4 backup via Rsync). The noise and power consumption of that system was overkill for what it was used for, so I sold it and went to a…

I forgot how to manage a server

Why don't we have Wayland on Raspberry Pi yet? (2018)
I have long wanted to create my own desktop operating system targeting the Raspberry Pi. I believe we should have a hackable desktop environment that is both powerful and lightweight, similar to BeOS and the Amiga. To build this desktop we really need full control over how apps draw to the screen, but still have…

The Fargate Illusion

‘AWS vs. K8s’ Is the New ‘Windows vs. Linux’
If, like me, you’re over 40 and work in IT, you’ll probably remember a time when everyone used Windows, and a small but growing proportion of people were wasting their lives compiling Linux in their spare time.

Give Me Back My Monolith
It feels like we’re starting to pass the peak of the hype cycle of microservices. It’s no longer multiple times a week we now see a blog post of “How I migrated my monolith to 150 services”. Now I often hear a bit more of the counter: “I don’t hate my monolith, I just care that things stay performant”. We’ve actually…
