Is there any particular difference between intval and casting to int - `(int) X`?
...e this is an old thread, and if you are still programming, then I hope you now see why this is actually the most obvious result. An int has no base because base is only used in string representations. Or more simply, an int of 12 in base 10 is the same as an int of 12 in base 99. It is still 12. ...

...lier without success, but perhaps something else was wrong. Trying it just now again, then re-creating the situation with another user, I found that this did in fact do the trick. Of course, the formal answer today was "not to be stupid" and to use REVOKE and DROP USER to do it right. I'm indebted t...
How to run test methods in specific order in JUnit4?
...e, why?
I'm not sure there is a clean way to do this with JUnit, to my knowledge JUnit assumes that all tests can be performed in an arbitrary order. From the FAQ:

Illegal mix of collations (utf8_unicode_ci,IMPLICIT) and (utf8_general_ci,IMPLICIT) for operation '=

UPDATE: utf8mb4/utf8mb4_unicode_ci is now the preferred character set/collation method. utf8_general_ci is advised against, as the performance improvement is negligible. See https://stackoverflow.com/a/766996/1432614

How do you create a Swift Date object?
...her date-times, you can use one of the following methods.
Method 1
If you know the number of seconds before or after the 2001 reference date, you can use that.
