Why shouldn't I use “Hungarian Notation”?
...
@Jon: if you have a variable name that does not fully give away what it is representing, then by absolutely all means the focus should be to rename it to something more descriptive (and Hungarian notation is not an improvement, in the very, very best case it is fi...
Why do I need Transaction in Hibernate for read-only operations?
...t option wasn't set explicitly.
But there is no guarantee that your method doesn't write into the database. If you mark method as @Transactional(readonly=true), Spring will set the JDBC transaction into a read-only mode, thus you'll dictate whether it's actually possible to write into DB in scope of...
Verifying a specific parameter with Moq
...roblem in the fact that Moq will check for equality. And, since XmlElement does not override Equals, it's implementation will check for reference equality.

It doesn't solve all problems, because Func (and Action) can't have out or ref parameters, but those are less commonly used.

Understanding implicit in Scala
...mplicit if you want, just like in any other val declaration. Here, request doesn't have to be marked implicit for this to type check, but by doing so it will be available as an implicit value for any methods that might need it within the function (and of course, it can be used explicitly as well). I...
Why are Perl 5's function prototypes bad?
...od calls completely ignore prototypes. If you're doing OO programming, it doesn't matter what prototype your methods have. (So they shouldn't have any prototype.)
Second, prototypes aren't strictly enforced. If you call a subroutine with &function(...), the prototype is ignored. So they don...
