... need to find elements in a container, and the search tag can't just be an index, then you may need to abandon std::vector in favor of set and map. Note the key word "may"; a sorted std::vector is sometimes a reasonable alternative. Or Boost.Container's flat_set/map, which implements a sorted std::v...

JSTL in JSF2 Facelets… makes sense?
...mponent already ensured the uniqueness of the client ID based on iteration index; it's also not possible to use EL in id attribute of child components this way as it is also evaluated during view build time while #{item} is only available during view render time.

Differences and relationship between glActiveTexture and glBindTexture
...bout the active texture.
Sampler uniforms are int values representing the index of the texture unit to use for the sampler (and not the texture object to use).
So you have to bind your texture objects to the units you want to use.
The type of the sampler will do the match with the texture target ...

What is an existential type?
... one type and one value. The universal proof is an entire family of values indexed by type (or a mapping from types to values).
So the difference between the two types you specified is as follows:
T = ∃X { X a; int f(X); }
This means: A value of type T contains a type called X, a value a:X, an...
What is a NullPointerException, and how do I fix it?
