Creating Charts with Rickshaw.js

I was recently introduced to Rickshaw, an open source JavaScript charting framework built on top of D3.js. Rickshaw specializes in creating timeseries graphs. When recently integrating Rickshaw into a project, I ran into a few hurdles that weren’t terribly well documented or explained online. In this post I’ll provide an overview of Rickshaw and go […]

Visualizing Project Scale, Risk, and Options

We discuss scale, risk, and different options with our customers and team members continually throughout the lifetime of a project. Having a visual representation of the conversation points can be very useful.

But if you try to peek inside a modern garbage collector, it’s very difficult to see how they actually work. There are thousands of implementation details that will confuse you unless you […]
