• Is it possible to use JSF+Facelets with HTML 4/5?

  - by Bytecode Ninja

  Facelets relies on XML namespaces to work with XHTML. How are HTML 4, and as far as I know, HTML 5 do not support namespaces. Also HTML 5 has some new elements that are not available in XHTML. Even HTML 4 and XHTML have some differences regarding elements and attributes they support. The question is: Is it possible to render HTML 4/5 documents using Facelets? If so, how?

• C/C++ Struct vs Class

  - by m00st

  After finishing my C++ class it seemed to me the structs/classes are virtually identical except with a few minor differences. I've never programmed in C before; but I do know that it has structs. In C is it possible to inherit other structs and set a modifier of public/private? If you can do this in regular C why in the world do we need C++? What makes classes different from a struct?

  Hi Complete novice question. I've used jQuery a bit, YUI not at all and know very little about it. I work on a website thats IE specific, we're now looking at making it cross browser. jQuery seems great at hiding the differences between browsers from a javascript point of view. However in terms of css layout is it YUI that I should really be looking at? thanks

  - by carrier

  Now that I've gotten relatively familiar with web2py, I'd like to give Django a go. What are the main differences? What would be the most efficient way to get started taking into account web2py knowledge? (It must help to have some python application framework knowledge,no?)

• What makes C faster than Python?

  - by Chris

  I know this is probably a very obvious answer and that I'm exposing myself to less-than-helpful snarky comments, but I don't know the answer so here goes. If Python compiles to bytecode at runtime, is it just that initial compiling step that takes longer? If that's the case wouldn't that just be a small upfront cost in the code (ie if the code is running over a long period of time, do the differences between C and python diminish?)

  Or is it now the other way around? From what I've heard there are some areas in which C# proves to be faster than C++, but I've never had the guts to test it by myself. Thought any of you could explain these differences in detail or point me to the right place for information on this.

• J2EE v6 and .NET 4.0 comparison

  - by sme89288

  We are running our applications on .NET 3.5 and are planning on either updating to .NET 4.0 or switching entirely to the Java platform, J2EE v6, as we've heard from some clients that "it's better." Can anyone either explain some of the large differences between the two platforms and maybe what kind of costs would be associated with switching to Java rather than just updating, or point me to some articles or papers that make such comparisons? Thanks!

• Jquery live() vs delegate()

  - by PeeHaa

  I've read some posts here and on the web about the differences of live() and delegate(). However I haven't found the answer I'm looking for (if this is a dupe please tell me). I know the difference between live and delegate is that live can not be used in a chain. As I also read somewhere delegate is in some case faster (better performance). So I am wondering is there a situation where you would use live instead of delegate?
