Possible to iterate backwards through a foreach?
...n with the List Reverse implementation.
It is possible to reverse certain ranges of a collection too, since Int32.MinValue and Int32.MaxValue are out of the range of any kind of collection index, we can leverage them for the ordering process; if an element index is below the given range, it is assi...

When are you truly forced to use UUID as part of the design?
... @Chamnap I wrote UUIDTools. UUIDs can be converted to an integer or their raw byte form, and would be substantially smaller as a binary.

(-2147483648> 0) returns true in C++?
... it. Value 2147483648 is apparently too large for the positive side of int range on your platform. If type long int had greater range on your platform, the compiler would have to automatically assume that 2147483648 has long int type. (In C++11 the compiler would also have to consider long long int ...
