charles
The second afternoon session I attended was about Charles, run by Karl von Randow.
Charles is a proxy which sits between your browser and the internet - you can see all the communication between websites like Twitter and Twitter apps like Twitterific. It does a whole lot of things in that space to make development a lot easier - especially for Flash developers. It has been in development for 7 years. Most of the updates and new features are developed directly related to user feedback.
Karl discussed the pricing and reason for making it an application that you need to purchase. The licensing is perpetual and entitles you to free upgrades - it’s also shareware. Apple, the BBC, Yahoo!, Boeing, AOL, Adobe, Google and Shift are just some of the companies who have single or multiple user licences. It does 30GB of traffic a month of 1MB downloads.
Seems like it has a lot of uses and if Shift wasn’t already using it, I’d definitely recommend it. I have decided however not to show my development ignorance by trying to add some of the examples here, but if anyone wants to, please add in the comments
