Service API changes starting with Android 2.0

Why is the C++ STL is so heavily based on templates? (and not on *interfaces*)
...y far more interested in generic programming, and why everyone are finally starting to realize that functional programming is quite clever as well. OOP on its own just isn't a pretty sight.

...fference between LL parsing and LR parsing is that LL parsers begin at the start symbol and try to apply productions to arrive at the target string, whereas LR parsers begin at the target string and try to arrive back at the start symbol.
An LL parse is a left-to-right, leftmost derivation. That i...
