Main Topic: Open Source GIS with Alastair Mayer

What do you get if you cross a map with a database? A GIS, or Geographic Information System. (Sorry, I couldn't come up with a funny alternative answer.) GIS systems are used at all levels of government, by utility companies, emergency services, real estate brokers, and anyone who has ever used MapQuest to get travel directions. They're used in planning, mapmaking, even archeological research.

There is a vast wealth of geographic data freely available on the net. There are also a number of Linux applications available (many free/open source) for viewing it, analysing and manipulating it, and creating reports, charts and maps from it. This presentation will give a brief introduction to GIS concepts and applications, demonstrate several free GIS packages available for Linux, and discuss some other uses of the technology.

Alastair Mayer has been designing and developing Unix software for nearly 20 years (Linux for nearly ten), including six years at GeoVision Systems, a major GIS vendor whose technology was acquired by Autodesk and formed the core of their Enterprise GIS Server. He has developed geographic analysis software for the Canadian Broadcast Company, mapping software for the Royal Australian Navy, and outside plant and facility management software for telecoms including US West (now Qwest), Southwest Bell, and Telebras, the Brazilian telephone company. He's also the architect and chief programmer of the open-source Cavor project.

KISS Session:Using Knoppix to Access Other Systems with Dennis Dallas

Dennis will discuss how he and a friend used Knoppix to gain access to files on a Windows NT system that had a lost system administrator password. They used the SAMBA facility to connect the Windows NT box (running Knoppix) to a Win98 system. Presentation Slides [77K Impress].

Main Topic: Gentoo Linux with Collins Richey

Gentoo is a highly-adaptable version of Linux that can be optimized and customized for just about any application or need. According to Collins: "I started experimenting with linux about 10 years ago — Slackware on a 386. When that machine died, I moved on to Caldera. After Caldera bit the dust, I ran Mandrake for a while and tinkered with Linux From Scratch. Then along came Gentoo, and I was hooked. I've put up RedHat, SuSe, and Fedora since then, but nothing satisfies like Gentoo."

Kiss Session: The Bochs x86 Emulator with Dennis Dallas

Bochs is a program that simulates a complete Intel x86 computer. It can be configured to act like a 386, 486, Pentium, or Pentium Pro. Bochs interprets every instruction from power-up to reboot, and has device models for all of the standard PC peripherals: keyboard, mouse, VGA card/monitor, disks, timer chips, network card, etc. Because Bochs simulates the whole PC environment, the software running in the simulation "believes" it is running on a real machine. This approach allows Bochs to run a wide variety of software with no modification, include most popular x86 operating systems: Windows 95/98/NT, all Linux flavors, all BSD flavors, and more.

Dennis will present an introductory over-view of what Bochs is and how to get started using it.

Main Topic: Application Portability Between Unix/Linux Versions and the POSIX Standard with Marc Rochkind

Marc Rochkind started his career at Bell Labs in 1970, where he was lucky enough to get into UNIX at its infancy. His best-known invention back then was the Source Code Control System, the ancestor of all modern version-control systems. He left Bell Labs in the early 1980s when personal computers started to get interesting. Since then, he has been a writer, teacher, consultant, engineering manager, and entrepreneur (having founded XVT Software, which sold a GUI-portability development tool). Now he's back to being a writer, and is a big fan of Linux, open source, and web-based applications.

Marc's latest book is the second edition of Advanced Unix Programming, available at SoftPro Books.

KISS Session: SSH with Dave Anselmi

SSH, the Secure SHell, is a secure replacement for telnet and ftp. We'll talk about why we call SSH "secure" and how to do remote login and file transfer using the programs in the OpenSSH package.

Dave is a self-taught programmer, system and network administrator, and Linux enthusiast. He has been dabbling in Linux since 1995 and is finally starting to understand a little of it.

KISS Session: Linux Q & A with a CLUE tech. panel

Is there something about Linux that you don't understand? How about that stupid question that you're just too embarrassed to ask in front of others? Now is your chance to resolve those issues, get your system running again or impress your friends with your new-found knowledge.

For the October KISS session, a panel of experts, or maybe even the entire audience, will pool their collective open minds and provide insightful reasoning to help you get your system in order.

Please submit your burning questions to the Admin group at the CLUE admin list. We will bring the top questions (and maybe some answers) to the October 12 meeting. Don't worry; your name will not be included with the questions (unless you want the credit). In any case, attend the next meeting to learn the answer to your question and to others that you may not even know you had. Please include the subject line: KISS QUESTION in your email and submit it by Friday, October 8.

Main Topic: Open Source Telephony using Asterisk with Tom Poindexter

Asterisk is a telephony platform that provides full PBX functionality, voice mail, conferencing, and call forwarding. Asterisk is also programmable so that specialized applications such as Interactive Voice Response and Automated Call Distribution can be quickly developed. Asterisk runs entirely in software but also interfaces with a number of protocols and hardware: Voice over IP (VOIP), as well as traditional digital and analog telephony devices are supported. Asterisk is primarily developed on Linux, but also runs on *BSD and Mac OSX, and enjoys a very active developer and user community.

The CLUE presentation will include the usual boring slide show and hopefully a live demonstration. A very special door prize will be given away to one lucky Asterisk wannabe.

Tom first booted and installed Linux 0.94 and has been a software developer/sysadmin/DBA for longer than he likes to admit. Tom develops and contributes to a number of open source projects. He has also been a past speaker at CLUE.
