Visual Improvements
No, my blog does not look any different; this is a kind of appendix to Kevin Marshall's post on free utilities highlighting a couple of free tools that you might find useful for XP and Vista:
CutePDF Writer - Download the free Ghostscript converter, then the Writer download. Install. Now when you want to save something to a PDF, if you can print it, you can select the CutePDF Writer print driver and convert it. This is very useful for saving off web pages in a readable format.
MS Office 2007 Add-in: Save as PDF - This comes directly from Microsoft and adds PDF as one of the options in the save as file dialog. Works with Word, Excel, Outlook, etc. This is one is particularly useful if you want to distribute a document without it getting modified along the way.
Windows XP ClearType Tuner - Again, this one is directly from Microsoft. If you have XP and you have an LCD, you should have ClearType turned on. ClearType will dramatically improve the appearance of text on a LCD and save you some eye strain. ClearType is on by default in Vista. I think this one is pretty well known, but if you have not tried it yet, give it a try for a few days and you won't want to go back to a screen without it.
4096 Color Wheel - This page allows you to easily find a particular color you want to use on a web page and get its color code for your HTML/CSS. You can either mouse over a part of the wheel or use the keyboard to slowly rotate through colors that are closely grouped.
