I attempted to implement a Monoid instance for a function a -> b.
instance Monoid (a -> b) where
mempty f = f
mappend f g = g . f
Please critique it for correctness and style.
In addition, I'm curious how mappend should be implemented. Should f or g be applied first?
I'm in the process of adding network support for a little Mac & Windows game I'm writing. Today I've finished the basic sockets plus a few other network helpers and would appreciate having the code reviewed.

I always forget how to do this efficiently with Vim's arglist. Drawing inspiration from a post over at stackoverflow, I wrote a Bash function to perform a project-wide search & replace.
It does the following:

Not exactly a complete script but still a worthy question
Take the following code for example:
if ($var == 1 || $var == 2 || $var == 3) { // do if true }
Is it possible shorten this, like so:
if ($var == (1|2|3)) { // do if true }
I'm always looking for ways to speed up development and if ...

etl currently has no wiki and three questions. It was mentioned that it may be a rebel tag.
For those that don't know, ETL is an acronym for Extract-Trsnsform-Load and is a term heard often in the database world. The problem I foresee is that you could potentially tag 50% or more of the sql ques...
NO, it shouldn't exist, not even be a synonym!
c# has major differences between versions, too. And yet, the only C# tag we have is c#. How do we address this?
C# 2.0 introduced generics. Enter the generics tag.
C# 3.0 introduced linq. Enter the linq tag.
C# 4.0 introduced the Task Parallel Li...

It's only simple, but is going to be part of a set of boilerplate files for future web projects, so I'm keen to get some feedback.
I should mention that not all exceptions will be left to this handler - this is for any that fall through the gaps during development. E.g. if my router throws a pag...

and

Which version of this syntax is more correct or more closely follows convention?
Does it even matter to people?
I have a group of tests that must be run in similar (but different) fashion and they have setups, results, etc. which are also similar but different. Great, I thought, I'll use interfaces to define these tests and setups. However, I can't implement the setups and results as the specific types, ...
