too many ways to develop for Symbian devices: native code, WRT (web run-time) widgets, Java, browser-apps, etc.

  What disadvantage did he find with having choice? Fragmented community, inconsistent UI, difficulty integrating with 3rd party apps, something else?

disjointed software updating -- which requires a Windows PC in older Nokia devices -- that leaves many North American users without fixes to serious issues for all but the most popular of handsets.

there is a little bit of hand-waving involved in calling JavaScript a functional language. JavaScript is not a side-effect free language, nor is it an expression-based language (i.e., it is not value-oriented, but rather variable-oriented). There is no tail call optimization in any of the current implementations, so recursion must be kept shallow. And the list goes on. Truth be told, JavaScript is really one of the first hybrid imperative-functional languages.

Higher-order functions allow us to do functional composition,

Since JavaScript does not have "overloaded" functions, this type of functionality is usually simulated using manipulation of the function's arguments. Currying comes in handy because it allows you to do this manipulation in a much cleaner and more modular way.

Closures have quite a few applications in real-world JavaScript: event binding, callbacks, sorting, mapping (in the classical Lisp sense), and many others. In more modern JavaScript programming, you can find them almost everywhere.

Standard fare for most dynamic data and the way most everybody would tell you to do it. Only thing is that it scales like a dog.

The thing is that holding all the weather of the entire globe in memory, well, takes a lot of memory. More than is reasonable. In which case, there’s a fairly decent chance that a given request can’t be served from the cache, resulting in a query to the database, an update to the cache, which bumps out something else, in short, not a very good hit rate.

If we were able to make our clients in London perform an HTTP GET on http://weather.myclient.com/UK/London then we could return headers in the HTTP response telling the intermediaries that they can cache the response for an hour, or however long we want.

Instead of getting hammered by millions of requests a day, the internet would shoulder easily 90% of that load making it much easier to scale. Thanks Al.
