O’Reilly Velocity Conference – Amsterdam

My favorite front-end conference has always been O'Reilly's Velocity Conference because the conference series has focused on one of the most undervalued parts of client side coding: speed.

One of the quickest and easiest website performance optimizations is decreasing image loading. That means a variety of things, including minifying images with tools like ImageOptim and TinyPNG, using data URIs and sprites, and lazy loading images. It's a bit jarring when you're lazy loading images and they just...

I've never met a person that is "ehhhh" about XHTML/javascript tooltips; people seem to love them or hate them. I'm on the love side of things. Tooltips give you a bit more information about something than just the element itself (usually...
