On the browser, we have . . . JavaScript.

On positive news it looks like Mozilla at least are interested in client-side support for Python and Ruby on the Tamarin VM, as is Silverlight on the DLR, but of course fragmentation is useless.

It’s not that I completely dislike JavaScript (JavaScript The Good Bits is an interesting read) but that lack of choice is bad.

I certainly agree about your comments regarding flex and silverlight’s proprietry standings and this is a real strength of Javascript! The future is intersting and not being tied to any particular technology I look forward to what it holds… Thank you for your comment

but objective-C has many features making Cocoa possible. cocoa is a really good mvc framework to create application

so, the main quality of “cappuccino” is the Framework, NOT the language, not “objective-J”, objective-J is here to make possible the recreation of Cocoa : cappuccino but it’s not the end. The end is a “web Cocoa” aka Cappuccino.

-
the javascript (and so whatever framework you want, sproutcore or cappuccino) is efficient, but it’s of course constrained by the browser

and that exactly where HTML 5, apple, mozilla, opera and now google are changing.

Canvas, local storage, many networks services, efficient execution, security and so on. More and more, the webbrowser is, from start, able to do what “external plugins’ was doing .

but with a plus : real control by the browser, real-time DOM manipulation, real desktop os integration, no more “black box” plugins (as Google explains they hate in their google chrome comics, simply old complains of webbrowsers developpers)

-
In the end, the browsers will be the platform, javascript its langage, frameworks the api.

-
flex is the baby of one company
silverlight is the baby of one company

it’s not good. it’s not efficient. it’s dangerous to build a business on it. and there are older stories to remind that.
