Eval in AS3: Tips for Executing Dynamic Actionscript

If you miss the eval method from AS2, the AS3 Eval library from Hurlant is what you're looking for. I found there were extras I needed so I created a wrapper class which you might find useful.

Regular Expressions: No Such Thing as Repeated Captures?

Finally found a tough spot where regular expressions don't perform. If you're trying to capture a list of values with unknown length, you could be up for some extra work!

Constellation Roamer Featured on Flowing Data

Nathan Yau just posted an article about the market for online visualizations and featured Constellation Roamer as one of the available "premium visualization" products.

I was always under the impression that a business account is something desirable, that there were benefits of having one. Maybe lower fees or advantageous account types. If you're a web-based freelancer thinking about a business account you might want to reconsider.

The Periodic Table of Visualization

Just stumbled on the periodic table of visualization which shows several different types of visualizations including tree maps, flow charts, and venn diagrams. Best of all, you can see examples of each by rolling over it's little square. Great resource thanks to Visual Literacy!
