Past Meetings

Note: this event will be held from 10am-4pm.

Software Freedom Day is an invitation to shape the future of our
digital world. Rather than being overwhelmed and controlled by the
many issues of our computerized age, the free software movement
harnesses the creativity of citizens worldwide. Free software treats
software -- the code that runs computers, cellphones, and other
technological devices -- as abundant, not scarce.
We are encouraged to use this abundance, learn from
it, and share our contributions with others. Although it sounds like
the geekiest holiday ever, the issues we celebrate on Software Freedom
Day affect everybody whose lives are touched by technology.

Software Freedom Day is celebrated in 64 countries across the world,
and for the fifth year in a row Waterloo Region is joining
the party.

This year, the Working Centre is running Software Freedom Day
celebrations on Saturday, September 22. The Queen Street Commons Cafe
will host talks suitable for non-technical audiences, on such
topics as the economics of Free Software, getting started on writing
your own software, and examples of open source in the photography
world. The Computer Recycling space at 66 Queen Street will host a
helpfest, where volunteers can help you install free and legal
software such as Ubuntu or LibreOffice on your own computer. There
will also be interactive demonstration machines and giveaways.
No matter what your level of computer skill, we invite you to join us:

FLOSS Fund Nominee: JQuery

Join us as we engage in free-ranging discussion. Maybe there will be tech demos too.

NOTE: This event will be held at the Rum Runner Pub in Kitchener. There is no admission charge, but the hosts ask that all attendees purchase something to eat and/or drink at the pub.

Here is a picture of the pub sign:

A number of KWLUG members will discuss topics related to the customization of Android phones:

- Making your phone run more smoothly
- Trying new firmware
- Beta-testing mods

Ralph Janke will demonstrate a use of the OpenLayers library that does not involve maps.

Jeff Voskamp will tell us about IPv6, an update to venerable IP addressing that we should all have known by now.

Note: The April 2012 meeting on the GIMP has been rescheduled to May.

Julie Dey will demonstrate some techniques and "how I did this" stories with the GIMP, a powerful photo manipulation tool.

Raul Suarez will then give a second presentation on other aspects of GIMP usage.

Note: The April 2012 meeting on the GIMP has been rescheduled to May.

William Park will show off AppGen, which is Enterprise Resource Management (ERP) software for UNIX. He will demonstrate the look and feel of this ERP implementation, and show how it can be used as a reference for future ERP development.

Darcy Casselman will show off Ubuntu TV, Ubuntu's cloud-connected entry into the PVR market.

Puppet is a powerful configuration management system that allows systems administrators to centrally configure and deploy computers on their networks. Eric Gerlach will tell us about its care and feeding.

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.

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

FLOSS Fund: MusicBrainz

Kiwi Ssennyonjo will talk about the latest release of pfSense, a powerful firewall distribution based on the BSD kernel. The firewall features: a powerful web GUI, easy rule editing, OpenVPN, pretty graphs, Captive Portal functionality, extensions/plugins, a large user base and much more.

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.

KWLUG held its first meeting on October 13, 2001, which means this month marks the 10th anniversary! Help us celebrate at this informal social event.

Join KWLUG as we celebrate Software Freedom Day 2011. There will be

- Presentations
- An install/supportfest (bring your computer!)
- Giveaways of CDs and DVDs
- Demonstration machines

and more.

Tim Laurence will discuss cryptography and the Secure Sockets Layer system that we all use for https webpages.

Tim kindly provided his presentation slides in Text Presentation Program format.

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).

NOTE: We are indeed having a meeting on July 4, because the Canadian holiday is Friday July 1 this year.
