This meeting will consist of three shorter presentations by KWLUG members.

Tim Laurence will present the Linux Volume Manager (LVM). He writes: "Partitioning without LVM is so 1988! With LVM you can gain flexibility to allow you to deal with all your changing and complex storage configuration needs with ease. Come learn how LVM can make your system administration easier."

Darcy Casselman will present Clutter. He writes: "Clutter is a library developed by Intel designed for building their smartphone user interfaces. It's open source and available for use on the desktop as well. Gnome is using it for Gnome Shell and Ubuntu is using it in their Unity netbook UI. Best of all, it's fun and easy to get started with it and see some nifty effects. We'll show you how to get started with Clutter in Python.

John van Ostrand will demonstrate Firebug, a useful (some would say essential) tool used to debug webpages.

Software Installer)
- using Debian packages low-level (apt, dpkg, dpkg-reconfigure,...)
- general how Debian works overview (philosophy + history + guidelines
+ outline of the system)

Programming For Linux

Meeting Date

The doors open for conversation, networking and casual Q&A some time between 6 and 6:30. Formal meeting and presentations start at 7:00pm sharp.

* * *
Raul Suarez will give a practical introduction to programming in Linux.

He writes: A very common question I've heard in on-line forums and casual chat is: "I'd like to develop for Linux, where do I start?"

This presentation is meant to provide an answer to that question. Probably not the ultimate answer and certainly not a comprehensive one as it won't cover every single possibility, but it should at least point the novice Linux developer on the right track.

Here I am using the term "developer" loosely, as my purpose is to include from the desktop user that needs to automate a repetitive task to the expert developer new to Linux development.

This will be an overview and a practical comparison of various programming alternatives available and the resources available to learn them.

From single line command line scripts to rich web applications to code-less programming there should be something for almost everybody.

As it is usual for my presentations, I'd like you to invite people that are (or could be) curious about developing under Linux. If you tell people, you'd be surprised how many may come just out of curiosity.

I've attached a map of the presentation in three formats:

  • If you install the FreeMind application you can use the mm version (best option)
  • If you like Flash, download the flash version to a directory and open the html in your favourite browser. It is interactive.
  • If you don't like Flash or don't want to install FreeMind, Just extract the html version to a folder and open it with your favourite browser.

Free Mind
Using FreeMind was invaluable to organize all this information. I highly recommend installing and using it.

You can find Free Mind in your favourite distribution repositories or directly at http://freemind.sourceforge.net/wiki/index.php/Main_Page

Demo Night

Meeting Date

The doors open for conversation, networking and casual Q&A some time between 6 and 6:30. Formal meeting and presentations start at 7:00pm sharp.

* * *
KWLUG members will give a number of quick (30 minute or less) demonstrations of assorted Linux goodies.

- Richard Weait will answer the question: "What Linux Distro Should I Use?"

- Rob Day will give a whirlwind tour of the steps involved in compiling kernels.

- John van Ostrand will give a presentation about DSL and houshold telephone wiring. He writes: "The presentation will be a brief discussion of the typical household telephone wiring and how to work with it with regards to DSL. I'll cover a few different termination blocks (demarc points) and how to work with them. I'll talk about the tools used to work with telephony lines. I'll talk about how houses are wired and how to alter that wiring to put a DSL filter on the whole household."

- Paul will give an introduction to GNU Screen, a program which manages multiple command-line windows effectively. Paul will cover basic usage and some configuration tricks like title bars and automatic window labelling that make Screen much more informative (and pleasant) to use.

This presentation is suitable for those new to virtualization and curious about it as well as those with moderate virtualization experience.

Update: Here are a tarball of the presentation slides.

Presentation topics covered ...

  • What is Virtualization?
  • What is QEMU?
  • What is KVM?
  • What is libvirt?
  • Do I need anything else?
  • How do I run all this?
  • What can I do with it?
  • How Does this compare with other solutions (e.g. VMWare, VirutalBox, and Xen).

You search text every day, often many times. Although much of that may be Internet searches, there are still lots of places to use the pattern matching power of Regular Expressions.

The cryptic looking regular expressions are usually quite simple. This presentation will help you understand the most commonly used features of regular expressions and will cover the most commonly used tools and a couple of programming languages.

So whether you are a graphical interface user, command line user, system administrator or programmer you'll find regular expressions useful.

When you cannot be there... Remote access and collaboration.

Meeting Date

In this presentation I will show how you can remotely access other computers to work as if you were in front of the keyboard or let other people view your desktop or control your computer, even behind firewalls. All using Free software.

The presentation will be at the end user level, showing the practical and hands-on side of it. The presentation is not about explaining the technology, just how to use it.

These are things that I use on daily basis for different purposes, from providing remote tech support to my father that lives in Mexico to using the main home computer when my children are also using it to working from home using the computer at the office to giving presentations remotely and hosting virtual meetings.

This presentation is a teaser of many different technologies and methods that could be full presentations on their own, but with full instructions on how to use each one of them. The technologies presented will include the following

  • SSH (Including reverse SSH)/putty
  • X over SSH
  • VNC (Including reverse VNC and VNC over SSH)/Vino/KRFB
  • NX No machine/FreeNX
  • Remote Desktop (Terminal services)
  • Web conferencing.(OpenMeetings, WebHuddle, DimDim, etc)

I'll do my best to set up a virtual meeting for those of you who cannot attend this presentation in person. I'll confirm if I can do it closer to the scheduled date and if so, post the details.

Edit:\
I've uploaded the presentations to this post and created a series of posts on my blog with more detailed information

Telnet
SSH
Putty
XDMCP
VNC (Virtual Network Computing )
NX
Web conferencing
Installing OpenMeetings on Debian Lenny

In this presentation, Khalid will go through various tools and techniques used to analyze performance issues with systems running Linux.

We will cover a bit of everything:
- Status tools
- Debugging/profiling, with an emphasis on performance rather than code debugging.
- Monitoring tools
- Statistics tools

We will examine live systems running the above tools where possible, in order to show real life data ...

Sometimes quick and dirty get the job done. As Perl programmers say "There
is more than one way to do it" and in the case of a finding out why a
program is not doing what you would like to do this is very true. One could
fire up the debugger and dig into the source code but often simpler and
faster methods are available. In the cases where you don't have the source
code these may be all you have. t

Here I will present a certainly incomplete but what I have found to be an
invaluable list of commands and techniques for trouble shooting software of
all kinds under Linux. On other platforms you will find similar commands so
these techniques need not be limited to Linux.
