Overloading member access operators ->, .*
...ary operator like +, -, and /. See also: Are free operator->* overloads evil?
.* and .
These cannot be overloaded. There is already a built-in meaning when the left-hand side is of class type. Perhaps it would make a little sense to be able to define them for a pointer on the left-hand side, bu...
What's the best way to refactor a method that has too many (6+) parameters?
...derstandable because the alternative was global data, and global data is
evil and usually painful. Objects change this situation because if you don't have something
you need, you can always ask another object to get it for you. Thus with objects you don't
pass in everything the method needs; i...
Best way to allow plugins for a PHP application
...o how does this work? Well, let's rule out eval() (which everyone says is "evil") and rule out that it's not an Observer pattern. So, the way it works is the sneaky empty class called Pluggable, which does not contain the methods and properties used by the Dog class. Thus, since that occurs, the mag...

Groovy: what's the purpose of “def” in “def x = 0”?
...oovysh allow you to do so), but in production code it's one of the biggest evils you can come across which is why you must define a variable with def in all actual groovy code (anything inside a class).
Here's an example of why it's bad. This will run (Without failing the assert) if you copy the ...
select * vs select column
...ure performance. As Knuth said: "Premature optimization is the root of all evil." When you get to the point where you need to worry about the performance of select columns vs. select *, (ask Twitter about RoR) you can worry about it and optimize it then.
