Comment What about Flash? (Score 0, Offtopic) 316
I love Google maps and I like what you can do with AJAX- but the fundamental problem with most browser based scripting technologies is that they're best at rending text. Don't get me wrong, anything that makes a webpage more responsive than the -click- load -click- is a step in the right direction.
Flash has earned a bad rep among programmers because it's often used for @#$?%! annoying and obtrusive ads and unnecessary web... page
My only beef with Flash is the vector rending pipeline. You get alpha for free but try overlaying a few transparent vectors and... performance... chugs. I'm crossing my fingers and hoping that the bitmap caching (you need the Flash 8 beta player to see bitmap caching in action) in the upcoming Flash 8 addresses this problem. The demo's I've seen look promising.
Check out Grant Skinner's or Yugo Nakamura work and if you want a great example of what you can do with real-time data in Flash- check out www.dentsu.com. What you see is the real-time position of all 30-some elevators in dentsu's corporate headquarters.
Disclaimer: I am currently a Flash Developer. If you want to see my work- it's at bodog.net. It's free online multiplayer poker and yes, those are real people playing. You can see the two technologies playing nicely together- the lobby was done using AJAX technology and the actual game tables are in Flash. Try refreshing the game table if you want an example of Flash using server-based persistance.
