This is a neat little library that allows you to:

Harness the power of type annotations and program specifications to make your code robust. It’s easy to get started.

It’s a quick process:

1. Annotate your functions with type signatures
2. TYPEDJS tests the annotated functions automatically
3. Find some bugs (but probably not all of them)

I think this is pretty neat.

Web Dev .NET: Differences Between jQuery .bind() vs .live() vs .delegate() vs .on().

With jQuery 1.7 came on() and went live(). live() was used and abused by many, so if you haven’t kept up with its deprecation, this article is for you.

Document are becoming even more dynamic, so managing your events can become a true test of your planning and logic skills. Unfortunately it’s also somewhat common to take the easy way out and end up with a situation in which you’re not careful with binding events. That leads to a degraded experience and slow running pages, something we want to avoid at all cost.

Elijah Manor is a super smart guy, and he’s put together an extremely straightforward piece outlining the difference between the various methods of binding in jQuery. Definitely set aside some time to give it a read.

Instagram in JavaScript.

I’m continually interested in learning more about canvas and really need to get in gear.

Speaking of js1k, my gosh check this out:

I mentioned that I enjoy trying to pick apart submissions to see just how they were done, but Román does that for us here. Awesome.

It’s that time of year again. If you’re not familiar with js1k, it’s defined as:

The object of this competition is to create a cool JavaScript “application” no larger than 1k. Starting out as a joke, the first version ended with a serious amount of submissions, prizes and quality.

The entries are often quite impressive and more than that, primed for learning. I always like spending some time digging through the submissions to see how creative people can get with their obfuscation.

This is an impressive piece of work. I’ve always been a sucker for nice looking charts and graphs, and flotr2 helps you build your own in canvas.

I’m definitely keeping this bookmarked for a project or two I’ve got in mind.

This is kind of blowing my mind right now, I’m not sure if it’s because of just seeing zip.js, but the fact that the goal of this library is to parse PSDs is amazing!

I made a quick test PSD catered to psd.js’s capabilities so far and it worked great. Testing a PSD from my latest client project proved to be a challenge but that’s completely expected and I hope to be able to take some time to review the code in more depth to see just how this thing is working.

Perhaps what excites me most is the roadmap for psd.js. I’m imagining the Photoshop-less tools that could be made to either extract data or more impressively convert data to new file formats for alternative image editors that have similar functionality to Photoshop.

I still nearly do a double take when I see headlines like this. JavaScript for disk operations? The true scope of HTML 5 is still settling in for me I suppose, but libraries like these are going to bring Web apps to the next level. Beyond that, a part of me feels that HTML 5 has surpassed the term “Web app” and something more appropriate should take it’s place, I just have no idea what that phrase should be.

This is a crazy awesome piece of genius from @rem:

As our Web apps become more mobile-aware, having a reliable way to develop and test with a primary consideration of motion was a tedious and difficult task, until today.

This is quite impressive. Based on Lettering.js, Arctext.js facilitates curving the path of text along an arc. Check out the demo for some nice examples.
