February 11, 2014 by

January 6, 2014 by

Performance Monitoring

If you’ve ever profiled code in Python, you’ve probably used the cProfile module. While the cProfile module is quite powerful, I find it involves a lot of boilerplate code to get it setup and configured before you can get useful information out of it. Being a fan of the KISS principle, I want an easy

The cause of the online blackout is this set of guidelines released by the Office of Management and Budget, and in particular their answer

TraceView APIv2
October 11, 2013 by

Performance Monitoring

Earlier this year my colleague TR wrote about the launch of our data API. I’m a big fan of making data more accessible, so I used our own API to write a Hubot script for exploring TraceView data without ever leaving HipChat. Even while I was writing that article, though, we were already lining up

Stacks of Cache
September 18, 2013 by

Performance Monitoring

Everyone likes cache. How can you not? In countless cases, you can remediate performance problems quickly and cheaply by adding a cache layer to your stack.
