What are the key differences between Apache Thrift, Google Protocol Buffers, MessagePack, ASN.1 and
...ol Buffers always explicitly encodes fields by numbers, and it is never an error at the library level if there are extra fields, and missing fields are not an error if they are marked optional or explicit. Thus all protocol buffers messages have EXTENSIBILITY IMPLIED.

ASP.NET MVC View Engine Comparison
...data model is essentially just string-concatenation, so syntax and nesting errors are neither statically nor dynamically detected, though VS.NET design-time help mitigates this somewhat. Maintainability and refactorability can suffer due to this.

C++11 rvalues and move semantics confusion (return statement)
..._ref = return_vector();
In the second example you have created a run time error. rval_ref now holds a reference to the destructed tmp inside the function. With any luck, this code would immediately crash.
Third example
std::vector<int> return_vector(void)
{
std::vector<int> tmp {1...
Why can't the C# constructor infer type?
...d not be unambiguously determined which was intended then we could give an error. This is the same as any other overload resolution problem; if insufficient information is supplied then we simply give an error.

What are the rules for evaluation order in Java?

Precedence and associativity only tell us that the assignment of zero to b must happen before the assignment to a[b], because the assignment of zero computes the value that is assigned in the indexing operation...
When and why would you seal a class?
...to cast a non-sealed class to any random interface, compiler doesn't throw error; but when sealed is used the compiler throws error that it can't convert. Sealed class brings additional code access security.
