throwing exceptions out of a destructor
Most people say never throw an exception out of a destructor - doing so results in undefined behavior. Stroustrup makes the point that "the vector destructor explicitly invokes the destructor for every element. This implies that if an element destructor throws, the vector destruction fails... The...
Why is extending native objects a bad practice?
...ollision, could you use a pattern where everytime you did this, you always confirm that the function is undefined before you define it? And if you always put third party libraries before your own code, you should be able to always detect such collisions.

How to reliably guess the encoding between MacRoman, CP1252, Latin1, UTF-8, and ASCII
... no bytes above 0x7F, then it's ASCII. (Or a 7-bit ISO646 encoding, but those are very obsolete.)
UTF-8
If your data validates as UTF-8, then you can safely assume it is UTF-8. Due to UTF-8's strict validation rules, false positives are extremely rare.

The only diff...
Parse usable Street Address, City, State, Zip from a string [closed]
... database of valid street addresses, parsing can be ambiguous and it can't confirm nor deny the validity of a given address. It can just try to pull data out from the string.
It's meant for the case when you need to get a set of data mostly in the right fields, or want to provide a shortcut to data...

... openPopUp();
}
I've tested version 1.0.1 on all browsers I have and can confirm that it works with:
IE9, IE10
FF 26.0
Chrome 34.0
... and probably all newer versions.
Doesn't fully work with:
IE8 - always indicate that tab/window is currently active (.now() always returns true for me)

Best way to compare two complex objects
...uld also handle cases where both references are null. If that check fails, confirm that your instance's field or property is not null (to avoid NullReferenceException) and call its Equals method. Since our members are properly typed, the IEquatable<T>.Equals method gets called directly, bypass...
Why does this method print 4?
... for 1 recursive call (1 more than original), the memory use is M + R. Suppose that StackOverflowError is thrown after C successful recursive calls, that is, M + C * R <= X and M + C * (R + 1) > X. At the time of the first StackOverflowError, there's X - M - C * R memory left.
To be able to r...
