...arched a lot. There seems to be no way of function pointer comparison. The best solution I got is to encapsulate the function or closure in an hashable object. Like:

...t_cipher_methods() for a list of the methods supported on your system. The best choice is AES in CTR mode:
aes-128-ctr
aes-192-ctr

There is currently no reason to believe that the AES key size is a significant issue to worry about (bigger is probably not better, due to bad key-schedu...
When should I use Arrow functions in ECMAScript 6?
...that should not access the thisObject.
The window object (global scope) is best addressed explicitly.
Many Object.prototype definitions live in the global scope (think String.prototype.truncate etc.) and those generally have to be of type function anyway. Consistently using function on the global sc...

... exciting uses of ternary syntax in your question; I like the last one the best...
x = (1 < 2) ? true : false;

...tremely hard. If possible, getting the user to specify the encoding is the best. Preventing an attack shouldn't be much easier or harder that way.
However, you could try doing this:
iconv(mb_detect_encoding($text, mb_detect_order(), true), "UTF-8", $text);

Creating an Android trial application that expires after a fixed time period
... Fantastic answer. Like you say I feel the second option is possibly the best. Its a shame google themselves don't offer some sort of licensing system as it may encourage both small and bigger brand developers to produce even more android applications.
