Earlier this year, I published an article that announced support for running Johnny-Five programs directly from an Intel Galileo Generation 2 single board computer. Since then, a lot of work has gone into fine tuning Galileo-IO, including a complete internal redesign that takes advantage of native I/O bindings and processing capability improvements whenever possible. Over […]

Selenium is an indispensable tool for developing web applications. It allows developers to write test scripts that control real browsers and ensure their applications behave in the way that users expect. Tests like these make software development much more pleasant–developers can have much greater certainty that their application is functioning correctly even after large refactoring […]

Software developers never want to do hourly time tracking. I’ve seen team leads who fill out the time tracking for their whole team to spare them the trouble. I’ve seen developers agonize over what to write down: they feel like they’re estimating even when it should be a simple matter of hours. Why is it […]

I’ve always been a huge proponent of building sites that work everywhere — any user, any browser, any device, any context. Websites work everywhere by default, and they stay that way so long as we know how not to break them. That’s what the Open Web means to me: ensuring that entire populations just setting […]

The Johnny-Five Tutorial Series is geared towards Arduino programming on Node.js, using the Johnny-Five framework. Get caught up here. When I first started writing (copy and pasting) JavaScript in 1999, I focused solely on IE 5 (available on PC, Mac and UNIX; but I had no idea what it was truly capable of) and concerned […]

Update: This proposal now has two open bugs for implementation, on V8 and SpiderMonkey. https://code.google.com/p/v8/issues/detail?id=3915 https://bugzilla.mozilla.org/show_bug.cgi?id=1135708 In this article, I’ll explore the process of adding syntax to a programming language by going through the process of designing a new JavaScript exponentiation operator, which I’ve submitted to TC39 for consideration in ES7. In many programming languages, […]

I’m honored to have been named lead maintainer of JSHint. Following in Anton‘s footsteps, I’m excited to carry on his vision for the project and see it forward. In addition to overseeing regular maintenance of the project, my primary goal will be to prepare JSHint for ES6. Stewarding this work will be an exciting challenge, […]

The Johnny-Five Tutorial Series is geared towards Arduino programming on Node.js, using the Johnny-Five framework. Get caught up here. In certain cases, it may be useful to know how much current is drawn from a specific load in a circuit. In this article, we’ll measure current draw, with and without a load. The load will […]

CSS is awful, but it doesn’t have to be that way. For example, new languages that compile to CSS like Stylus, Less, and Sass have made it much less painful to lay out and style web projects. However, these projects are limited: they provide delicious, delicious sugar, but ultimately they are using the same core […]

We can create charts quickly when working with D3.js and standard DOM elements, but that comes with a key limitation: the number of nodes we can render is fairly small. Have you ever tried to render a scatterplot with 1000+ circles in SVG? If you have, then you’ve probably seen your browser crumble under the […]
