Thank god for Postfix. Simple to configure. Damn near secure. So much nicer than messing with sendmail or qmail. Not to mention numerous papers on security, and it looks like he's also worked on patches to introduce taint checking into PHP. Not to mention creating the TCP wrappers library. He's all over the place.

We discovered a couple little annoyances with IE6, and I thought it would be useful to publish their workarounds.
Issue #1:
Random text would "disappear" on a page. It actually was still there and would show sometimes after hovering over it. The fix turns out to be setting the CSS for the text in question to "height: 0.01%" - it's so simple but so needless. It shouldn't have to be done. It should just work.
Issue #2:
<a href="javascript:anything" onclick="something()">
Won't work. It will just act like a dead link (or perhaps just ignore the onclick...) This will work however:
<a href="javascript:something()">
Note: Typically I try to keep my href's to be plain "javascript:;" if I need to use anchor-based links, and then chain events off of it using the element's ID and jQuery.
