A few years ago, I worked as a sales executive for an Internet service provider. One of the first things suggested to me was to watch Learn To Subnet: A Free Lecture-based Educational Course on IP Addressing and Subnetting.

You might think that this is the last thing you need to learn, so why watch it? Trust me, you will be pretty impressed with yourself when you understand, and can explain, how binary math is used to calculate IP addresses and how subnetting works. Try it. you will be enlightened!

Here are some great free font websites:

Webpage Publicity Agency – 6500 free fonts
Acid Fonts – Large collection of free fonts
org.opn.src – Open source pixel and led fonts for flash
Fonts for Flash - Pixel Fonts and Super Pixel Fonts for Flash

GUIStuff.com offers a variety of resources for web developers, including a complete CSS 2.1 reference and a collection of CSS and JavaScript tutorials. They also provide a collection of free Pre-Designed Web Templates in the following formats:
-Layered Photoshop file
-TIFF source file
-Sliced images within HTML

I actually did this a while ago, but think it is a very useful tip.

I used to be quite frustrated about the fact that I could only download 2 files at any given time with Internet Explorer (IE). I found this great article at the Small Business Computing website, and was able to increase the maximum number of simultaneous downloads to 10. What a pleasure!

I did this on a Windows XP machine. The registry changes might differ on older or newer Microsoft operating systems.

Here is a list of screen resolutions. If I have not listed one, please add it to the comments for this post.
