IE7 invokes a DHTML behavior to load and parse all style sheets into a form that Explorer can understand. You can then use most CSS2 selectors without having to resort to CSS hacks.  
The behavior is lightweight and is automatically loaded via a CSS inclusion. No alteration of your original document is necessary. Nor do you have to alter your CSS.
A very clever solution to a very irritating problem. Especially with all the IE rendering bugs.

It's like slashdot, except useful and without trolls - mainly because I don't think there's any such thing as a user account there! It's a good clearinghouse of stories, howtos, reviews, and more on cool tech stuff.
This is a validator for syndicated feeds. It works with RSS 0.90, 0.91, 0.92, 0.93, 0.94, 1.0, and 2.0. It also validates Atom feeds.

To use it, simply enter the address of your feed and click Validate. If the validator finds any problems in your feed, it will give you messages for each type of problem and highlight where the problem first occurs in your feed. If you're unsure what a message means, click the "help" link next to the message for a fuller explanation.

Why a validator?

Despite its relatively simple nature, RSS is poorly implemented by many tools. This validator is an attempt to codify the specification (literally, to translate it into code) to make it easier to know when you're producing RSS correctly, and to help you fix it when you're not.

Cory writes in the latest Wired magazine about Asimov bringing robots into the popular culture and the new release coming to theatres this summer.
The cross-browser rich-text editor implements the Mozilla Rich Text Editing API included with Mozilla 1.3+. There is NO LICENSE, so just take the code and use it for any purpose. This code is 100% free. Enjoy!

Requires: IE5+/Mozilla 1.3+/Mozilla Firebird/Firefox 0.6.1+ for all rich-text features to function properly. If browser does not support rich-text, it should display a standard textarea box.

Yes, it works quite effectively.. it's not perfect, but it'd be hard to rewrite a full-blown WYSIWYG editor in javascript. There's a demo at the link, or you can see a more visually appealing (meaning less crap, larger editing area) here.

note: Don't bother clicking the submit button on the site's demo, it's useless. Use the "View Source" checkbox instead.

Upgrade to the newest version of Windows Update.  
In addition to an updated look, this will allow you the option of installing beta and release candidate versions of MS software.  
this will let you install RC2 of XP SP2, if you want it.
Zero - AI Chatbot
Zero is an artificial intelligent chatbot that is being designed by Computer Hope as a way to help develop a Natural Language Processing and Fuzzy Logic script for helping its users locate answers to their computer questions by parsing large logs of computer help conversations and help that is available from the Internet.

Zero's knowledge is currently comprised of numerous logs of other peoples conversations in IRC and other chat networks, logs and transcripts of other peoples conversations with other bots, and knowledge it has gained by talking with other users.

I've been playing with this for the last two hours or so. :) It's a learning AI chatbot. You can connect to it via IRC if you have it, or there's a web-based interface too (which is what I was using). Use your Linkfilter username if you go in, so we know who we all are.

also, this one isn't a contender for the Filterbot, as source isn't being released as of yet. I just thought it was too cool not to post. Don't forget to ask it "Do you know what linkfilter is?" ;)

This is great! If you come across a site that requires registration, just go to BugMeNot and get a generic login...
Cooperative Linux is the first working free and open source method for optimally running Linux on Microsoft Windows natively.  
More generally, Cooperative Linux (short-named coLinux) is a port of the Linux kernel that allows it to run cooperatively alongside another operating system on a single machine. For instance, it allows one to freely run Linux on Windows 2000/XP, without using a commercial PC virtualization software such as VMware, in a way which is much more optimal than using any general purpose PC virtualization software.

The Epic of Gilgamesh
The Epic of Gilgamesh is, perhaps, the oldest written story on Earth. It comes to us from Ancient Sumeria, and was originally written on 12 clay tablets in cunieform script. It is about the adventures of the historical King of Uruk (somewhere between 2750 and 2500 BCE).  
For something so old it's a surprisingly easy and interesting read.  
ECTOR, the chatterbot.
ECTOR is a project of a chatterbot, that tries to learn from the utterers' entries.  
It has several version (including an online one, written in PHP/MySQL), but the last one, and most up-to-date is written in C, and runs under Linux (or Windows, but with less accuracy).  
The fun is to download its C version, and run it. Now, you can teach it what you want, and see what it learns, "understand", and replies!
One of the biggest difficulties in migrating from Windows to Linux is the lack of knowledge about comparable software. Newbies usually search for Linux analogs of Windows software, and advanced Linux-users cannot answer their questions since they often don't know too much about Windows :). This list of Linux equivalents / replacements / analogs of Windows software is based on our own experience and on the information obtained from the visitors of this page (thanks!).

Another useful site. I wonder if the reverse type exists..
