Pro Web
Hehe, let us know how it went. The one I am going to is the 24th in New York.
Tech Talk was great. Nice for Apple to encourage developers. Core Animation is going to be awsome! I expect you will see it in subtle but significant ways.
One thing I took away from this was that Leopard is not anywhere near being done. Also, don't expect a radical change in the UI. There will be refinements, but it won't be substantially different as per previous rumors. They did show some things for the Finder and Spotlight I probably shouldn't say anything about. But, it was super nice.
That being said, I do believe that Apple is going to extend the UI in various ways that will be application specific. Time Machine is a perfect example. One way this will be accomplished is full screen mode like in iPhoto. Add to that Spaces and you get an idea how your desktop experiance is going to change -- for the better.
One thing I found interesting, as a web developer, was how much Python kept coming up in the discussions. Though, Apple is improving Cocoa, it's clear to me that Objective-C is the language of choice for OS X applications. There are bindings for Python and Ruby, but they seemed to be using Python for various things.
Speaking of Python and Ruby, it is possible that Apple will add a scripting editor for coding languages like Ruby and Python. I don't think they have decided yet, or it may come later as part of a yet announced technology.
The Wiki server in OS X server is driven by Python and JavaScript. I had heard another rumor that Apple was working on some sort of Web based technology for writing web sites. Nothing was said about this, but if true, I would expect it will use Python. Again, this is just my impression, so I'm probably wrong.
I would love to see Apple do this however. I like Ruby on Rails, but after seeing what they are doing with their Wiki, interface-wise, the thought that they might release a framework to create an Ajax like interfaces, similar to what I saw, with simplicity and ease would be awesome. WebObjects just isn't going anywhere. Since it's Java based, I suspect Apple is going to leave it as a back end technology.
But when you see how awesome these new UI designs are that run on OS X, there is going to be a desire to adapt this to the web. I don't know, I'm just rambling, but that Wiki looked really cool and was clearly taking desing cues from other OS X applications.
Adobe has Flex, Microsoft has .Net 3.0, there are a number of open source Ajax technologies, so what is Apple bringing to the web space? They didn't say, but one can hope. Perhaps some "pro" iWeb technology.
