With a nearly 30-year history of continuous development, the BSD family of free open-source operating systems are undoubtedly the heir of the UNIX legacy. While their boisterous second cousin has garnered the bulk of the media attention and rabid cheer-leading has gotten the attention of corporate boardrooms, the BSDs, in general, prefer to remain low-key, quietly building on their reputation of solid reliability, suitable for servers, desktops, and embedded systems.

In this session we'll cover:

• History and development of UNIX.
• UNIX in academia and the advent of the Berkeley Software Distribution.
• Contributions of Berkeley UNIX to computing.
• Toward a complete and completely free UNIX^WBSD.
• Genesis of the BSDs, NetBSD, FreeBSD, OpenBSD.
• Project goals
• Different, but similar.
• (Installation examples)
• What do you get? How do you get more?

NewI\O http://www.newio.org is a new approach to internet applications. Instead of kludging the world web web (which was designed for hypertext document display) to run apps, NewI\O builds a system from the ground up for this purpose. It is similar in some ways to many existing technologies, like the web, java, remote desktop systems, etc, but is not exactly like anything else. Come see a report of current progress of the system to include a discussion of the design descisions, system architecture, and aspects to programming for the system, including how easy it would be for you to write internet apps more powerful than anything ajax can do. See a demo of the system in action. Try it yourself from your seat.

Mike Roberts has two years experience as a Linux Support Engineer for Rackspace Managed Hosting. In that time he has found that mastery over Regular Expressions consistently distinguishes between novice and expert technicians. For your next skill-set upgrade Mike will teach a class entitled "System Administration by Regular Expression Manipulation" in the Saturday afternoon session. Don't let the scary title intimidate you. If you can navigate the command line and handle a few basic 'grep' uses then you're ready for the jump-start into Posix Extended Regular Expressions all the way. Mike will teach:

• advanced 'egrep' usage
• 'sed' and 'awk' from the command line
• writing script files for 'sed' and 'awk'
• shell tricks to glue this all together

Tweeks will be giving a "State of the Linux Desktop, touching on where the Linux Desktop has been and then drilling into where it is today. He will be start by talking about some of the historical "Desktop Problems", then cover some of the new technologies that are making the average user Linux Desktop a reality and then will compare the major desktop distros. He'll then review a list of the most commonly requested Windows/Linux equivalence apps (App A in Windows = App B in Linux) to help Windows users who want to move to Linux but need to get their work done in their new Linux desktop environment.

This talk will cover:

• History of the Linux Desktop
• New Advances, Products and Technologies
• hotswap, udev/hal, dbus
• XGL, AIGLX,
• Xen, VMWare, XoverOffice
• Top Commercial and Community Desktop Distros
• Windows/Linux Equivalence Applications (A on Win = B on Lin)
• Business Related Issues in Moving to Linux

LAMP Programming is becoming a very important tool for creating and maintaining robust and attractive web sites. LAMP programming uses the PHP scripting language to bind together some very useful tools: Apache, the number one HTTP server on the Internet, and MySQL, the most popular open-source database available today. PHP is growing by leaps and bounds, and can be used for a variety of scripting tasks. This can all be done with very simple and freely available tools in many operating environments, but the Linux Operating System is preferred for its stability and reliability.

Topics to be covered include:

• Installing and testing Apache, MySQL and PHP installations
• Integrating PHP and HTML
• Targeting a PHP script from an HTML form
• Retrieving information from MySQL databases
• Accessing MySQL information from PHP scripts
• There will be plenty of opportunities to practice the skills presented
