The ultimate anti-style guide for programmers.
There's some pretty good stuff on there...
Semicolons! Always use semicolons whenever they are syntactically allowed. For example:
if ( a );
else;
{
int d;
d = c;
}
Some of the things on the page at http://mindprod.com/jgloss/unmainobfuscation.html reminds me of coding styles used by people who don't realize their style is ridiculous.
