High-Availability Linux

Meeting Date

Aden Seaman will discuss a number of technologies and tricks he discovered in setting up a two-node high-availability cluster in his own home. He will give an overview of how DRBD block device mirroring, OCFS2 shared disk filesystems, GlusterFS cluster filesystems, clever network configuration, and the Pacemaker and Corosync cluster resource tools can work together to make a high- availability computer cluster. He will also briefly touch on integrating User Mode Linux virtual computers, an Asterisk PBX, and a DSL and firewall setup with the cluster. Finally he will give a live demonstration of his system.

Unity, Gnome-shell, and the fuuuuutuuuuure

Meeting Date

Note that we will be holding this meeting on January 9, even though technically January 2 is a non-holiday Monday.

* * *
The GNOME desktop environment has recently released version 3, and with it a new interface called the GNOME Shell. The Ubuntu project has developed an alternative interface called Unity. In this presentation, Chris Irwin will tell us why GNOME Shell is awesome, and Darcy Casselman will do the same for Unity.

Some aspects they may cover include:

  • Change is not (always) evil
  • The common underpinnings and goals of Unity and Gnome Shell
  • The benefits of competition
  • Extensions
  • Common complaints and rebuttals

Batch Video Editing, FLOSS in the Developing World

Meeting Date

We have two presentations lined up for this month.

Rodrigo Gonzalez will give us a short presentation on "Free Software in the Developing World". This may turn into a series of short presentations on free software adoption in different geographic areas.

Raul Suarez will give a talk on batch editing tools. He writes:

GUI Video editors are great for one-offs but very time comsuming when you need to repeat the same video process to multiple videos.

There are several very powerful free software command line utilities that can be used for scripting those repetitive tasks.

I started investigating using them to edit my presentation videos consistently and, althogh I found that the learning curve is steep, one can start with cookie cutter recipies and evolve from there.

In this presentation I will go through some of those recipies using mainly mencoder, ffmpeg, imageMagick and a few other tools I've found along the way.

Big Blue Button, RealLife Mobile Messaging

Meeting Date

Big Blue Button is open-source web conferencing software geared towards education. It features live video chat, VoIP communication, document sharing and much more. Raul Suarez will discuss Big Blue Button:

- What it is
- How to set it up
- How to use its Web API
- How to integrate components

In addition, Norman Young will demonstrate a mobile phone app he created called "RealLife Mobile Messaging". He writes:

Despite running on Linux, Android incurs a paradigm shift from
traditional application programming. On Android, you don't call the
System, the System calls you! This introductory talk reviews the
presenter's experience in re-targeting a messaging application from
Python and GTK on the Maemo Nokia N800 Tablet to Android. We compare
Android's architectural components (Activity, Service, Intent, Content
Provider, and Broadcast Receiver) to their approximate counterparts on
Linux (GUI, Job, Message RPC, File system, and Signal).

KWLUG Meeting: July 4 2011

OpenVPN server and/or client is available on a wide range of hardware from routers to servers running BSD, GNU/Linux, Windows and MacOSX.

Topics of discussion:
1) Generating your own Certificate Authority with Easy RSA. Creating and maintaining certificates and keys for use with OpenVPN.
2) Setting up a simple point-to-point VPN connection between an OpenVPN server and remote client.
3) Routed VPN - the Road Warrior.
4) Bridged VPN - just like being there.

Demo Night: Clutter, LVM, Firebug

Meeting Date


(We only video for Darcy's part of the presentation)

and a link to the video if the embedded version does not work.

* * *
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.

KWLUG Meeting: Monday, February 7 2011

of his awesome automatic installation presentation)
- creating Debian packages
- using Debian packages high-level (aptitude, synaptic, Ubuntu
Software Installer)
- using Debian packages low-level (apt, dpkg, dpkg-reconfigure,...)
- general how Debian works overview (philosophy + history + guidelines
+ outline of the system)
- how to configure the "Debian Way" (network, kernel compilation, how
things fit in with the LSB?)

For the technical side of things, Kyle will give a high-level overview of Tor: how it works and why you'd use it. Other privacy-enhancing technologies can be discussed, such as PGP, WikiLeaks, etc."

KWLUG meeting: Monday, August 9 2010

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
