Introducing the Web Platform Contribution Guide

Ergonomic Testing with Webpack, Part One, File Resolving

This is part one in a series on the intersection of module bundlers and testing frameworks. Our focus will be webpack and jest but the techniques explored here can be reused with other tools as well. Modern websites and applications are routinely built by combining hundreds of small JavaScript modules. In order to increase the […]

And so, we have started to fill in […]

Using SVG Patterns as Fills

Back in the day, before color printers (or printers at all), people still had to make good data visualization. One way to do that was by using patterns instead of solid colors to indicate changes in scale or category. For example, take a look at this set of pie charts, using different patterns for different […]

Customizing the RobotsConf Sumobot with Johnny-Five

In the first post in this series, I walked through inventory, preparation, calibration and assembly of the SumoBot Kit that was provided to all attendees of this year’s RobotsConf. From there, I showed how to control the bot with an Arduino Uno, Electric Imp and Spark Core. In this article, I’m going walk through two […]
