Proxy Objects:
In your time as a Perl programmer, it becomes almost inevitable that at some point you will have to manage in-memory tree structures of some sort. When you do this, it becomes important to be aware of how Perl manages memory, and when you might come up against a situation where Perl will not free its memory -- a situation that can happen easily ... as we'll see below.
Covers reference counting, a neat "weak references" technique I didn't know about in Perl 5.6, and the proxy object design pattern (although there I stopped reading, no time  ).
More stuff about XHTML2. Kuro5hin: First XHTML 2.0 draft published. Most of the content was clearly taken from Mark's site, but they have some other stuff, like xforms, xframes, and XML events.
Oh, and re: the <line> element: I love how the W3C authors don't use their own markup for their examples. They use <p class="program"> instead of <code>. Grr!
It also looks like the Edit Module is totally new, and have they gotten rid of the <a> tag altogether in favor of allowing anything to be a link? I also just noticed that <script> is still PCDATA for whatever reason.
Via Madville.com, Fox News: FBI Informant Wearing Wire Captures Sounds of World Trade Center Attack. Make sure you watch the video.
NEW YORK -- An FBI informant wearing a wire to secretly record a conversation with a city tax assessor ended up making what is believed to be the only known uninterrupted audio recording of the Sept. 11 attack on the World Trade Center.
From Answers in Genesis, there's a 'counter-program' and tutorial in response to Dawkins' silly "Methinks it is like a weasel" program. This is from the introduction to the tutorial:
The astronomer, Fred Hoyle said the probability of the formation of just one of the many proteins on which life depends is comparable to that of the solar system packed full of blind people randomly shuffling Rubik's cubes all arriving at the solution at the same time. [see ref] . In response to statements like that, evolutionists try to avoid the issue by breaking evolutionary stages down into small and gradual steps. Richard Dawkins is a prominent atheist and author of the book, The Blind Watchmaker, [see ref]. Dawkins puts forward the idea that cumulative selection is able to produce complex proteins (such as haemoglobin), which are obviously too improbable to arise in a single step. Dawkins wrote a computer program to demonstrate cumulative selection and mentions this program in his book. The program would select a random sequence of letters and gradually mutate this sequence until it matched a phrase that Dawkins selected from Shakespeare's Hamlet. However as you read this tutorial you will see that when Dawkins' program is correctly understood, it not only fails to provide any real support for molecules-to-man evolution, it can in fact, be used to demonstrate problems with the theory of evolution.

Fun rant from Christine:
Sex makes babies. I've said it before, and I'll say it again. If you're not married, don't know the guy or girl well enough to say that you even love them, then you probably shouldn't be having sex. I know, I know ... it's fun and all that, but do you want to have a kiddo with the person? Ok. Then don't have sex. (And if you have sex and get pregnant, please respect life enough to not throw your baby in the trash. Please.)
Ha, they named the probe going up to look for life on Mars the "Beagle 2". Of course, the Beagle was the name of the ship Darwin was on when he did most of his research.
I just got news from Buy.com that the Spider-Man DVD is ready to pre-order and is coming out on November 1st. Unfortunately, the original teaser trailer will not be on the DVD Boo on Sony.
