Encryption. Steve Friedl's Tech Tips. Does this site look plain?
This site uses advanced css techniques Unixwiz.net - Software Consulting Central Steve Friedl's Tech Tips This is a collection of tips on a very wide-ranging list of topics, some of which are not terribly technical. If I solved a problem that I thought others might need, I put it here so the search engines would pick them up. Table of Contents Those who wish to reproduce these elsewhere will find that a polite request in advance usually gets a positive response. Finally, as of February 2009, I have an RSS feed for these Tech Tips. Some Tips have outlived their usefulness, but we nonetheless archive them here. This is all original material, and some Tips are in multiple sections.
