Unit tests on RDO package builds by jpena

Unit tests are used to verify that individual units of source code work according to a defined spec. While this may sound complicated to understand, in short it means that we try to verify that each part of our source code works as expected, without having to run the full program they belong to.

Lessons from OpenStack Telemetry: Incubation by Julien Danjou

It was mostly around that time in 2012 that I and a couple of fellow open-source enthusiasts started working on Ceilometer, the first piece of software from the OpenStack Telemetry project. Six years have passed since then. I’ve been thinking about this blog post for several months (even years, maybe), but lacked the time and the hindsight needed to lay out my thoughts properly. In a series of posts, I would like to share my observations about the Ceilometer development history.

Comparing Istio and Keystone Middleware by Adam Young

One way to learn a new technology is to compare it to what you already know. I’ve heard a lot about Istio, and I don’t really grok it yet, so this post is my attempt to get the ideas solid in my own head, and to spur conversations out there.

Multiple 1-Wire Buses on the Raspberry Pi by Lars Kellogg-Stedman

The DS18B20 is a popular temperature sensor that uses the 1-Wire protocol for communication. Recent versions of the Linux kernel include a kernel driver for this protocol, making it relatively convenient to connect one or more of these devices to a Raspberry Pi or similar device.

Generating a list of URL patterns for OpenStack services. by Adam Young

Last year at the Boston OpenStack summit, I presented on an Idea of using URL patterns to enforce RBAC. While this idea is on hold for the time being, a related approach is moving forward building on top of application credentials. In this approach, the set of acceptable URLs is added to the role, so it is an additional check. This is a lower barrier to entry approach.
