OpenStack Paris Summit Retrospective

Wednesday, December 17, 2014 » community

During the week of the summit, I observed three important trends in the OpenStack ecosystem. First, private clouds are starting to take on the characteristics of public clouds.

And finally, interns are taking a greater role in delivering new features across various OpenStack projects.

Redis Lua Scripting for Performance

Wednesday, November 19, 2014 » code

NoSQL tends to force a lot of data model logic into the app layer, making it hard (or even impossible) to optimize certain types of operations.

The Face of the Cloud

Tuesday, February 05, 2013 » stuff

It's no coincidence that cloud computing and post-PC devices became popular at the same time. But why didn't all this happen years ago when tech heavyweights were pushing thin clients?

In which I pit uWSGI against Gunicorn and stumble upon a Python stack that leaves Node.js begging for mercy.

Wednesday, December 12, 2012 » performance

In this latest round of performance testing, I take the Tornado web framework for a spin (heh, couldn’t help myself), and also play around with Cython.

Check out these results from a round of rigorous performance testing comparing Python, PyPy and Node.js
