Speaker:  Jeffery Cann
Title:  Demystifying Regular Expressions (regexps)

Abstract

Regular Expressions are a powerful concept which can elevate your Linux skills to the 'guru' category.  The Linux Operating System is full of utilities where it's possible to use regular expressions.  I will cover the definition of a regular expression, how to write regular expressions, and some common examples.  By the end of the 1/2 hour session, attendess will be able write simple regexps and will have the fundamental understanding of regexps necessary to write advanced expressions.

Speaker:  Liz Coolbaugh
Title:  A Tour of Linux Distributions

Abstract

The Linux operating system, spoken of so much recently, is composed of the Linux kernel, licensed under the GNU General Public License (GPL), and a great deal of additional software, licensed under a variety of "free/open source" licenses. Because it is freely available and redistributable, there is no one vendor from which the operating system is purchased. Instead, any person, organization or company can choose to develop and maintain a Linux "distribution", a specific set of software packages, bundled with the Linux kernel.

Some people are unaware of just how numerous and diverse Linux distributions are. Others fear that the availability of multiple varieties of Linux will fracture the Linux market and keep vendors from choosing to support it. In this talk, we'll examine the breadth and diversity of Linux distributions, through well-known ones such as Red Hat, Slackware, Debian, etc., to over a hundred lesser known ones. We'll look at the reasons numerous distributions have come into being and how to choose between them. Then we'll finish up with a look at the advantages and disadvantages that the diversity of Linux distributions brings and what the Linux community is doing to control the disadvantages while enjoying the advantages.

About the speaker: Elizabeth O. Coolbaugh is the co-founder of LWN.net, also known as the "Linux Weekly News", an on-line magazine that has been reporting on the Linux Community since January, 1998. Ms. Coolbaugh has worked in computer systems administrations since 1981, with Unix since 1985 and with Linux since 1997.

Previous Topics

Meeting Date:  12 December 2000

Main Topic:  Open.  For Business. (7:15 pm)
Brian Cabral and Todd Gibson:

The GNU/Linux and Open Source revolution is proceeding at lightning speed. As businesses hear about and begin to learn about GNU/Linux and other Open Source tools, their first question is "Why Bother?" and their second question is "What's in it for us?".

This talk looked at how businesses make their IT decisions and why they should be choosing GNU/Linux and Open Source solutions.

Although the talk was not the typical CLUE "tech talk", it presented some valuable ideas about how to promote the use of GNU/Linux and Open Source solutions in your business and your customers' businesses.

I gave brief background on CVS, where to obtain it, installing it on your system, and reasons why you should use it (even if you are an individual developer.)

I discussed some of the common commands like logging in, importing existing software, creating new projects, and keeping the repository in sync. Mention will be made of some common situations with multiple developers and the best way to work together.

I briefly covered platforms other than Linux, and some front ends to CVS to make it easier on the novice user.

Meeting Date:  9 May 2000
Main Topic:  Setting Up and Using the SGI XFS Filesystem on Linux (7:15 pm)

Eric Eastman said:

This talk will cover how to download, build, and use the Linux version of SGI's XFS filesystem and will go over the advantages of XFS as compared to the Linux EXT2 filesystem. The XFS filesystem is a World-Class high performance 64-bit filesystem that was originally developed for SGI's IRIX version of UNIX that has now been released as Open Source software under the GPL, and is currently in early beta for Linux. With the XFS, "fsck" checks are a thing of the past, as XFS uses journaling technology to enable sub-second filesystem recovery after a system crash. XFS is designed for heavy production use and scales to support filesystems and file sizes of millions of terabytes.

Eric Eastman has been a System Engineer with SGI since 1996, specializing in large disk and tape storage systems. Eric has a BS in Mathematics from Metropolitan State College of Denver and first started using LINUX 1995.

KISS Session Topic:  VMWare Matt Durrell discussed the VMWare emulator.  It allows you to run many operating systems within Linux.


Meeting Date:  11 April 2000
Main Topic:  XML (Extensible Markup Language)

Uche Ogbuji said:

If you duck past all the hype about XML, you will find that it truly brings about the potential to revolutionize information exchange. This is not because of any intrinsic merit in angle brackets and the like, but for a more fundamental reason that Linux users are especially likely to appreciate: openness.

XML is all about opening up the rules and formats involved in processing data. This is of particular interest to Linux users because proprietary data-formats have long closed off many important applications to Linux. XML and its related technologies are a powerful tool in making Linux as serious a data-processing environment as any other.

In my talk I shall give a very brief overview of XML. Then I shall talk in rather more detail about some of the key technolgies surrounding XML, such as XSLT, RDF and XLink. Finally I shall cover a selection of Linux and OSS projects making use of XML, including Mozilla, GNOME and Cocoon.

Uche Ogbuji is co-founder of Fourthought, Inc. a software-development consultancy specializing in middleware applications using open technologies, including Linux, XML, Python and CORBA. Uche Ogbuji has given many presentations on Linux, Python, XML and database programming, and has written many articles on these topics, especially in LinuxWorld. He is currently working on a book, The Linux Database Bible.

Main Topic: TCP/IP Networking, Part 2 -- UNIX Configuration

Part two will built upon the basics of TCP and IP discussed in Part one.  The presentation started with a terse presentation of the materials not covered in part one: TCP, protocol layering, and TCP/UDP port numbers.

The main emphasis of the presntation focused on how the unix "utilities", non-kernel parts of the system, utilize the TCP/IP stack to provide services such as ftp, http, mail, remote file services, etc.  Substantial attention was given to 'inetd', the "Inet Super Server", with subsiquent time applied to other common services not covered under the inet umbrella.  Basic configurations of 'inetd', as well as a loose discussion of other, non-'inetd' application configurations were also covered.

KISS Session Topic:  Lynn Danielson discussed Windows and Linux networking using SAMBA Configuration.
