Justin Love will be giving us his Canvas presentation he gave in Chicago this past month. Details to come.

A new member, Nick, will also be covering the basics of SASS.


Paths, Properties, Paint: HTML5 Canvas and the Pervasive Pixel Painting Protocol

Sometimes, stacking divs and fiddling with CSS just doesn't cut it.
The canvas tag gives us an escape hatch - an infamous blank rectangle.
Unlike applets and Flash, canvas is orchestrated by the same
javascript you already use to run your web site. Canvas is a strange
beast however; while it gives us a "blank canvas" perfect for painting
and blending effects, the API is largely vector based, which makes it
easy to do shapes and outlines that can be smoothly transformed.

We'll take a deep dive into the way canvas "thinks" - the drawing
model that you'll need to bend it to your will. This same drawing
model reappears in a number of other systems. Along the way we'll
also take a short peek into computing history to see how this hybrid
vector/raster model came about.

Justin Love started tinkering with canvas 2007, before it escaped from
the OS X Dashboard to the larger web. He has also implemented most of
the canvas API to create a canvas-to-postscript converter.

Justin has programmed everything from microcontrollers to SQL and
FoxPro to C++, and currently runs the Chicago Javascript group and
helps out with the ChicagoRuby group. He is currently working on a
mobile web product and light consulting, with a few talks at user
groups and conferences for kicks.


We start showing up at 6pm for food, drink and socializing.

Presentations start at 7pm
