Transport yourself back to 1982. Wow, the news was so much more bite-sized then. Not like now.

Description: Rickshaw is a JavaScript toolkit for creating interactive time series graphs. Looks nifty. Free, open source, MIT licence, developed at Shutterstock.com.

So we recorded and setup detailed notifications for every email bounce, to make sure that we are always aware of what’s happening (thanks Mailgun!). And we soon started to see patterns.

People would misspell their email addresses and be unaware of it, resulting in a delivery failure and a lost user. And it got even more interesting - most of these invalid email addresses were a result of a misspelled domain; “hotmail.con”, “gnail.com”, “yajoo.com”. A clear opportunity for improvement.

You can get the Mailcheck.js plugin at Github. Neat.

"I don't really care that Google is tracking what I click, and I don't really care about the extra indirection when I click on a result (though both are concerns). But I find it annoying that I can't copy-paste a result by simply right-clicking on a link and choosing “copy link address”"

The solution turns out to be quite simple.

"Vector math is pretty much essential when you want to do any kind of physics simulation, be it as simple as a bouncing ball. While my goal originally was to implement a flocking simulation (like birds flying close to each other, but not too close), the lack of math skills led me to build a bouncing ball simulation first."

You never know when this will come in useful.

Really excellent fun. Keep and study. Obviously, you'll need an HTML5-capable browser to see them.

"Tangle is a JavaScript library for creating reactive documents. Your readers can interactively explore possibilities, play with parameters, and see the document update immediately. Tangle is super-simple and easy to learn."

Tangle is HTML5 goodness. Swallow it whole.

"It can't hurt if we put 'attr(disabled) in can it?"

A fun exercise is to dig through the CSS files that Brandon has, um, linked to and figure out where the image has been added - and how Alfredapp.com avoids displaying it, since it's using the same CSS

Just in case you needed another HTML5/CSS3 playground: "HTML5 and CSS3 bring loads of new features and functionality to the modern web. This site is a resource and showcase of some of the newest, and most expressive features being added to the web today."<br />

However, here's what you might not expect: it's by Adobe.
