Do one thing… I don't want barely distinguishable tools that are mediocre at everything; I want tools that do one thing and do it well. I’ve been lamenting the demise of the Unix philosophy: tools should do one thing, and do it well. The ability to connect many small tools is better than having a single tool that does everything poorly. That philosophy was great, but hasn’t survived into the Web a

Swarm v. Fleet v. Kubernetes v. Mesos Comparing different orchestration tools. Most software systems evolve over time. New features are added and old ones pruned. Fluctuating user demand means an efficient system must be able to quickly scale resources up and down. Demands for near zero-downtime require automatic fail-over to pre-provisioned back-up systems, normally in a separate data centre or r

A tale of two clusters: Mesos and YARN With Myriad, analytics can be performed on the same hardware that runs your production services. This is a tale of two siloed clusters.

The second cluster is the description I give to all resources that are not a part of the Ha

Yes, CSS is code Learning from "The Humble Border-Radius" One of the best things I overheard at the Fluent Conference was (more or less): “CSS live coding? I was like, that isn’t code.
