Matt's First Law of User Interaction: What's obvious to the programmer will not be to the
user.
First Corollary to MFLoUI: You haven't made it obvious enough.
Second Corollary to MFLoUI: The program's testers will ask the dumbest questions
you can possibly think of.
Matt's Second Law of User Interaction: Users are evil incarnate. They will break your code,
overrun your buffers, circumvent your error checks, and
make it your fault.
Corollary to MSLoUI: Test your program with tame users first.
Matt's Third Law of User Interaction: Users will not be happy with your program unless they
can make it behave like the program it replaced.
Corollary to MTLoUI: Every interactive program should admit, support, or
include vi-like movement keys.
Matt's Axiom: The maximum amount of fun you can have writing code is
inversely proportional to the code's immediate user base.
Snippets of code should be wrapped in
<code> tags not<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
