Data visualization tools

With the increasing availability of big/open data more people discover a need to make it understandable. One way of understanding data is by looking at it. As I have received a lot of questions lately here is a roundup of tools you can use to create visualizations of data. I have divided the tools into three groups: Libraries for using in your own web project. Client side applications that generate a standalone visualization....

On the management of software projects: Programming management will continue to deserve its current poor reputation for cost and schedule effectiveness until such time as a more complete understanding of the program design process is achieved. We build systems like the Wright brothers built airplanes — build the whole thing, push it off the cliff, let it crash, and start over again....

Changing energy behavior with real-time feedback

In this blog post I try to put household energy usage in a control theory context to see if we can find better ways to influence behavior. A lot of people are thinking about how we can reduce household energy use these days.

The idea is to provide a framework that allows for an increasing semantic interoperability emerging over time without having a large centralized organisation defining vocabularies. Main points:...
