Rails: confused about syntax for passing locals to partials
...tly pass values the same way all the time, and you won't have problems. In order to learn about this, I went directly to the code itself (actionpack/lib/base.rb, render() method in Rails 2; Rails 3 is different). It's a good exercise.
Furthermore, don't worry about "bothering" people on SO. That's ...

How to get the parents of a Python class?
...
Usefully, this gives you all ancestor classes in the "method resolution order" -- i.e. the order in which the ancestors will be checked when resolving a method (or, actually, any other attribute -- methods and other attributes live in the same namespace in Python, after all;-).

Should I use @EJB or @Inject
...epend on @EJB's attributes like beanName, lookup or beanInterface) than in order to use @Inject you would need to define a @Producer field or method.
These resources might be helpful to understand the differences between @EJB and @Produces and how to get the best of them:

...Resizable-array implementation of the List interface.
Interface List - An ordered collection (also known as a sequence). The user of this interface has precise control over where in the list each element is inserted.

How is __eq__ handled in Python and in what order?
a == b
It is generally understood, but not always the case, that a == b invokes a.__eq__(b), or type(a).__eq__(a, b).
Explicitly, the order of evaluation is:
if b's type is a strict subclass (not the same type) of a...
Is it worthwile to learn assembly language? [closed]
...ut cpu pipelining, branch prediction, cache alignment, SIMD, instruction reordering and so on. Knowledge of these will help you write better high-level code.
Furthermore, the conventional wisdom is to not try to hand-optimise assembly most of the time but let the compiler worry about it. When you s...

Do I cast the result of malloc?
...chael Anderson () issue aside, note that your suggested style switched the order., Consider when element count is computed like length*width, keeping the sizeof first in this case insures multiplication is done with at least size_t math.
