How to sort an IEnumerable
...
Smart idea and naming! But why the double casting anti pattern in listToSort = (src is List<T>) ? (List<T>)src : new List<T>(src);? What about having it like listToSort = (src as List<T>); if (null == listToSort) listToSort = new List<T>...

What is the most efficient Java Collections library? [closed]
...
As other commentators have noticed, the definition of "efficient" casts a wide net. However no one has yet mentioned the Javolution library.
Some of the highlights:
Javolution classes are fast, very fast (e.g. Text insertion/deletion in O[Log(n)] instead of O[n] for standard StringBuffe...
Forward declaring an enum in C++
...ifferent sizes, but I'm fairly sure that data pointers have to round-trip (cast to another data pointer type, then back to the original, need to still work), which implies that all data pointers are the same size.

What do people find difficult about C pointers? [closed]
... left till someone tries to build a compiler.

How will I know when to create an interface?
...
You don't have to cast, as opposed to 50 different classes with a Process method. C# doesn't use "duck typing", so just because A has Process() and B has Process() doesn't mean there is any generic way to call either. You need an Interface for...
How to get my IP address programmatically on iOS/macOS?
...he case where sa_type == AF_INET6, you're taking the IPv6 address and type-casting it to IPv4 and turning that to a string (basically from the high 32 bits of the 128-bit address.)
