Gruber posted a video of a website that does some dodgy history insertion. Go to tgdaily.com let it load (it has horrible perf so give it a bit) and click back and you’ll notice that you get taken back to exitjunction.com with tgdaily as a query. Insert rage face here. Once past rage face open dev tools and investigate. Continue reading
I’ve been deep in the Angularjs world and have gone through the many emotions other developers have expressed. One thing that is lacking is best practice on testing, although yearofmoo has a huge article on testing which improves this greatly. I still had some trouble and I thought I’d post this to help others. Continue reading
Source maps are awesome but one issue is that compiling from x-lang to JavaScript is a single level of mapping, if you want to go from x-lang > JavaScript > minified JavaScript you couldn’t as closure compiler, currently, only has a single level of mapping, until now. UglifyJS2 allows you to specify an input source map from the first stage of compilation, enabling multi-level mapping. Continue reading
Let’s face it doing thorough client-side unit testing fills me with rage, throw mobile browsers into the mix and I want to start flipping tables. There are tools out there to somewhat tackle this issue but they either require painful setups or want you to rewrite your unit tests using their framework. What if I told you there’s a tool that is easy to get up and running, doesn’t require you to rewrite your tests and allows you do it all from the command line in desktop and mobile browsers. Watch a video showing it working.

Have you ever found yourself wishing you could keep your client-side code readable and more importantly debuggable even after you’ve combined and minified it, without impacting performance? Well now you can through the magic of source maps.
Last year, I did a quick 5 min presentation on some of the features available in Modernizr for Web Directions What Do You Know event. From there, Sitepoint & Learnable’s Kevin Yank asked me to put together a short course for learnable.com based on the presentation. So after working on the occasional weekend I put it all together and got it launched just before xmas 2011. Continue reading
So the other day it hit me that since iOS safari supports contenteditbale it should surely have support the clipboard events and other handy bits and pieces. Like any good hacker I created a testcase to find out basic support of events and getting selection range values, and as expected the support is pretty good. Let’s dive deeper. Continue reading
Here’s a super awesome trick I had no idea about until someone pointed out you could do this. addEventListener can take an object as a second argument that will look for a method called handleEvent and call it! No need for binding “this” so it will pass around the context correctly, the context is the object you’ve just set as the event listener callback. Continue reading
In preparation for a talk I’m doing at Web Directions South I needed to be able to put video into fullscreen mode from within my HTML based slides. In order to do this I imagined I would of needed to use flash but thankfully Webkit nightly, Chrome dev and Firefox nightly have added the ability to put HTML5 videos, and other elements, into fullscreen mode using javascript. The FullScreen API now updated to point to official editor draft, thanks Hans!.

The other day I was writing some updates and improvements for Modernizr, one to detect for generated content support and two to improve stylesheet and element injection. Modernizr already in a few places inserts a stylesheet and a corresponding element to do some tests e.g. generatedcontent, touch, css3transforms and a few others. All this happened multiple times; each test would inject an element and an inline style element, do its test then remove both elements. All this happens while the page is loading and as you can see the more tests that involve these steps exponentially grow the number of times it needs to touch the DOM. Continue reading
