Does the C++ standard mandate poor performance for iostreams, or am I just dealing with a poor imple
Every time I mention slow performance of C++ standard library iostreams, I get met with a wave of disbelief. Yet I have profiler results showing large amounts of time spent in iostream library code (full compiler optimizations), and switching from iostreams to OS-specific I/O APIs and custom buffer...

Why does base64 encoding require padding if the input length is not divisible by 3?
...s are concatenated, it's impossible to recover the original data because information about the number of odd bytes at the end of each individual sequence is lost. However, if padded sequences are used, there's no ambiguity, and the sequence as a whole can be decoded correctly.
Edit: An Illustration...
Where does Scala look for implicits?
