In an expertly designed data visualization, the Times guided us through its own version of events, which boils down to: Hamas started it, and Israel responded in self-defense. Data from the last three flare-ups is included in the same way, gently suggesting to readers that this is a pattern.

What follows is a breakdown of some ways that design can be misused to tell a biased story.

Using #Vagrant to deploy 14 VMs in @awscloud -- should I really be getting so many "request limit exceeded" errors?

Rigs of Rods is an open source vehicle simulator licensed under the GNU General Public License version 3. What makes Rigs of Rods different to most simulators is its unique soft-body physics: vehicles, machines, objects, etc. are simulated in real-time as flexible soft-body objects, giving the simulation an extremely accurate behavior which entirely depends on the physical construction of the vehicles or objects you create. The community contributes greatly to the game, giving it a vast selection of vehicles and terrains from which you can choose.

Today's word: tyromancy (n.) the art of divining the past or future by interpreting omens found in cheese.

Good morning! (at Riksbron)

Profiling data can be thousands of lines long, and difficult to comprehend. Flame graphs are a visualization for sampled stack traces, which data allows hot code-paths to be identified quickly. See the Flame Graphs main page for uses of this visualization other than CPU profiling.

Flame Graphs can work with any CPU profiler on any operating system. My examples here use Linux perf_events, DTrace, SystemTap, and ktap. See the Updates list for other profiler examples, and github for the flame graph software.

My goal in this guide is both to answer these questions, and, more importantly, provide an overall framework you can use to think about how to answer these questions.

The LedBorg provides a tri-colour LED controllable from the Raspberry Pis GPIO header. Using simple on / off logic it can provide a total of seven colours as well as off. Using software based pulse width modulation (PWM) it is capable of many more colours, around a million in fact.
