...lass) is always valid with both static_cast and dynamic_cast, and also without any cast, as an "up-cast" is an implicit conversion. Regular Cast These casts are also called C-style cast. A C-style cast is basically identical to trying out a range of sequences of C++ casts, and taking the first C++...

... x is very very close to 0, sin(x) == x is the right answer. A bit further out, sin(x) uses the familiar Taylor series. However, this is only accurate near 0, so... When the angle is more than about 7°, a different algorithm is used, computing Taylor-series approximations for both sin(x) and cos(x)...

... may access it before it is fully constructed. Most of the discussion is about what happens to the state of the map object, but this is irrelevant since you never modify it - so the only interesting part is how the HashMap reference is published. For example, imagine you publish the map like this:...

... only stores string credentials (username/password). However, I have found out that when you set the kSecClass to kSecClassCertificate or kSecClassKey the Keychain checks also if the entry (the value) is already stored. This prevents from adding the same certificate or key twice. Also if you specify...

...tchers concurrently. Pattern.matcher() is safe to construct matchers without synchronization. Although the method isn't synchronized, internal to the Pattern class, a volatile variable called compiled is always set after constructing a pattern and read at the start of the call to match...
