ruby 1.9: invalid byte sequence in UTF-8
...-op, and no checks are run. Ruby Core Documentation for encode. However, converting it to UTF-16 first forces all the checks for invalid byte sequences to be run, and replacements are done as needed.

Why does C++11 not support designated initializer lists as C99? [closed]
...
In other words, designated initializers support a programming style where internals are exposed, and the client is given flexibility to decide how they want to use the type.
C++ is more interested in putting the flexibility on the side of the designer of a type instead, so designers can make it e...
How can I use interface as a C# generic type constraint?
...
The closest you can do (except for your base-interface approach) is "where T : class", meaning reference-type. There is no syntax to mean "any interface".
This ("where T : class") is used, for example, in WCF to limit clients to service contracts (interfaces).

Function pointers, Closures, and Lambda
I am just now learning about function pointers and, as I was reading the K&R chapter on the subject, the first thing that hit me was, "Hey, this is kinda like a closure." I knew this assumption is fundamentally wrong somehow and after a search online I didn't find really any analysis of this compari...

Why is it impossible to override a getter-only property and add a setter? [closed]
... { return _currentBar; }
}
Since Bar cannot be set as per the BaseClass interface, BarProvider assumes that caching is a safe thing to do - Since Bar cannot be modified. But if set was possible in a derivation, this class could be serving stale values if someone modified the _source object's Bar ...

When would you use delegates in C#? [closed]
...here takes a delegate as a parameter. Since delegates are just function pointers when you pass the method name into the .Where(delegate) that becomes the delegate. Since inMyFamily returns a boolean type it is actually considered a predicate. Predicates are just delegates that return booleans.

How to count the number of set bits in a 32-bit integer?
..., you may need to adjust it to work for a particular language (e.g. using uint32_t for C++ and >>> in Java):
int numberOfSetBits(uint32_t i)
{
// Java: use int, and use >>> instead of >>
// C or C++: use uint32_t
i = i - ((i >> 1) & 0x55555555);
