General

• http://www.jnd.org/dn.pubs.html - a collection of essays on various topics from design to technology & society. A good place to look for an inspiration when designing just about anything I think.
• http://www.start.com/myw3b/ - a beta version of an interesting online service to read RSS feeds online. It uses AJAX to dynamically load everything on the fly. (got link via http://blogs.msdn.com/msnsearch/archive/2005/06/04/425205.aspx)
• http://sandbox.msn.com/ - a place where various Internet related tools developed by Microsoft are available for download.
• http://www.rss-specifications.com/rss-submission.htm - RSS submissions list. A page with collection of various RSS directories to submit the blog to.

Tools

• http://extensionroom.mozdev.org/more-info/sessionsaver - Session saver extension for Firefox which saves opened web-pages and tabbs when Firefox is closed and reopens them when it restarts.
• http://chrispederick.com/work/firefox/webdeveloper/ - Web developer Firefox extension. A powerful tool that allows to do such neat things as changing CSS on the fly to see the changes on the screen right away. I'd love to see some similar tool to appear for IE also.
• http://jgwebber.blogspot.com/2005/06/drip-02.html - Drip 0.2. Some minor improvements over Drip 0.1. Also the source code has been released.

Web development

• http://web-graphics.com/mtarchive/001568.php - "Javascript: what's next?" An interesting article on where Javascript is today and where it is headed. Provides a lot of links to things people are doing with Javascript.
• http://www.opensourcecms.com/ - web page with a list of various open source tools to be tested online before you download and install them. Truly gives a new meaning to "try before you buy it."
• http://www.htmldog.com/ptg/archives/000107.php - a post on how to do multiple backgrounds in CSS with a lot of interesting points and ways to do it discussed in the comments.
• http://blogs.msdn.com/ericlippert/archive/2003/09/17/53028.aspx - Eric Lippert writes about closures in Javascript. What's more important is what he says towards the end of the post - how closures can cause memory leaks in IE and why Microsoft hasn't fixed the problem yet.

Development tricks

• http://www.informit.com/articles/article.asp?p=167842&rl=1 - a really interesting article on how to do policy-based class development in C++ using templates and multiple inheritance. Policy-based classes allows the user of the classes to configure how an object is made and how it works by specifying from which classes the object is built.
