ORDER BY the IN value list
...r but note that array_position does not work with bigint and you'd need to cast: order by array_position(array[42,48,43], c.id::int); which, may lead to bugs in some cases.

How different is Objective-C from C++? [closed]
...Objective-C is a more perfect superset of C. In C and Objective-C implicit casting from void* to a struct pointer is allowed.
Foo* bar = malloc(sizeof(Foo));
C++ will not compile unless the void pointer is explicitly cast:
Foo* bar = (Foo*)malloc(sizeof(Foo));
The relevance of this to every da...
Why array implements IList?
... (and transitively, ICollection) simplified the Linq2Objects engine, since casting the IEnumerable to IList/ICollection would also work for arrays.
For example, a Count() ends up calling the Array.Length under-the-hood, since it's casted to ICollection and the array's implementation returns Length...
Is there a way to iterate over a slice in reverse in Go?
...rface{} will not take a []string as input anymore. Even if string can be casted in interface{}, []string cannot be casted in []interface{}. Unfortunately, the present reverse function is the kind of function that needs to be rewritten a lot.

1. Solution with dynamic
In C# 4.0 and higher versions, you can simply cast to dynamic and write:
if (nodes.Any(n => ((dynamic)n).Checked == false))
Console.WriteLine("found not checked element!");
Note: This is using late binding, which means it will recognize only at runtime if the o...
How to do exponentiation in clojure?
...ately represented by doubles anymore, there really is no problem with just casting the result to int. 2) I don't see how writing Math/pow is more complicated than math-pow or whatever the name would be if there was a clojure equivalent. If there already is a simple java method that does what you wan...
How to round up the result of integer division?
...
For C# the solution is to cast the values to a double (as Math.Ceiling takes a double):
int nPages = (int)Math.Ceiling((double)nItems / (double)nItemsPerPage);
In java you should do the same with Math.ceil().
