Suppose you need to create a function for adding two numbers together in plain C. How would you write it? What sort of an API would it have?...
I frequently read about proposals for new solar power developments where the resulting power is moved great distances to less sunny places, such as northern Europe from the Sahara, the US North Eas…
Peter Bourgon has a web site, and this is that web site.
You're probably reading this page because you've attempted to access some part of my blog (Wandering Thoughts) or CSpace , the wiki thing it's part of. Unfortunately you're using a browser version that my anti-crawler precautions consider suspicious, most often because it's too old (most often this applies to versions…
A quick overview of Linux settings I change on almost every machine I manage.

Building resilience teams with chaos engineering principles.
How do you debug an application, library or an entire system with multiple processes? One answer: tracing. An introduction into bpftrace, and an overview of the Linux tracing ecosystem (DTrace, eBPF, uprobes, etc).

Looking beyond the hype and explaining why microservices should nearly become extinct.
There are many great options for managing FreeBSD Jails. iocage, warden and ez-jail aim to streamline the process and make it quick an easy to get going. But sometimes the tools built right into the OS are overlooked.
Migrating from a server-based solution to S3 static website resulted in increased performance and decreased costs
1 I usually rely on Minikube , though other solutions exist, like Kind , that can actually emulate multiple nodes. Multi-node support may eventually come for Minikube. A year ago, I decided I would build my own Kubernetes cluster. As a software engineer, I either use a local single-node Kubernetes cluster 1 , or a…
Let's take a look at the state of netbooting for Raspberry Pis including how and why you'd build a cluster and how well containers play with network booting
