I’d assumed the Go compiler provided a robust abstraction across CPU architectures. Code that ran on one CPU architecture would run on another. It turns out I was wrong. In this post, I provide a minimal example application that demonstrates the importance of field alignment when using sync/atomic and 64-bit values.
If you work with Kubernetes, you’ll be aware of the config file that defines contexts. This config is what kubectl uses to gain access to a cluster. I work with a large number of ephemeral clusters and have found that this config is difficult to manage. This post shows how I’ve switched to using individual config files for each cluster.
So you’ve done the Kubernetes thing, you have micro-services, and use all the frameworks. You’ve rolled out one or more continuous thing doers and have more metrics than you know how to dashboard. Despite all this, you are struggling to release products as fast as the business would like. It might be time to explore your path to production.
As a child, I had a nasty experience involving pizza, anchovies and a small fish bone. I’ve never touched anchovies since and it has taken me a long time to get used to the idea of eating fish at all. But that’s not what I’m here to write about. I’m here to share a different experience of fish bones, the fishbone diagram.
To capitalise on modern platform capabilities, applications need to be platform aware. They need to be cloud native. An oft overlooked example is health probes. Without these endpoints, platforms can only make crude assessments of applicat
Anyone looking for statistics on their blog will find themselves pushed towards the big names in web analytics. In return for statistics, you are encouraged, if not required, to gather more information about your readers than strictly necessary. Even if you gather statistics from your server logs, you are almost certainly logging unnecessary information about visitors. It doesn’t have to be this way.
I’ve been looking to start practising my Chinese more deliberately than I have been, particularly my character recognition. I couldn’t find any character practice sheets that I liked and so I made a couple of my own.
I’ve been working with a container image for a Django application and was surprised to find that an image for a simple application was 1.2 GB. I wanted to understand how this storage was being used and came across Dive, a tool for navigating container layers.
Docker Compose provides a succinct way to define services that make up an application. However it doesn’t allow services to be marked as optional so everything is started by default. In this post I outline a use-case for optional service and show how I defined service dependencies to provide a solution.
The sidecar is a multi-container pattern used to provide additional functionality to a containerised-application without requiring changes to the application itself. The sidecar is the foundation of popular tools like the Istio service mesh. But how does it work? In this post, we’ll learn more by implementing one from scratch.
