One of the worst kept secrets about AJAX on the web is that the underlying API for it, XMLHttpRequest, wasn't really made for what we've been using it for. We've done well to create elegant APIs around XHR but we know we can do better. Our effort to...
CSS animations are a lot of fun; the beauty of them is that through many simple properties, you can create anything from an elegant fade in to a WTF-Pixar-would-be-proud effect. One CSS effect somewhere in between is the CSS flip effect, whereby there's...

Hey David,
My favourite client side performance testing tools are
1- Chrome Dev Tools
2- Gtmetrix
3- Pingdom (to some extent)
4- & sometimes New Relic helps a lot.
Chrome Developer Tools is the best without any doubts
I do not have a favorite tool as I am new to the testing and DevOps world. I would greatly benefit from the tickets by jump starting my learning as I am already passionate about learning these skills. Please help a developer discover the way! I will return the favor!
