Past Meetings

Every so often a group of KWLUGers volunteers to rescue laptops donated to the Computer Recycling project at The Working Centre. For assorted reasons it is not viable for Computer Recycling to spend much time refurbishing these laptops itself, so we sort through them, select ones in reasonable condition, then install Xubuntu on them for resale.

You are invited to come help! You do not need to be a Linux nerd or a hardware genius to participate: if you can use a screwdriver, read numbers and follow instructions then you can be helpful. There will be lots to learn, but you can learn it as you go along. Linux nerds and hardware geniuses are also welcome to participate, of course.

To participate, please RSVP using the Contact Us functionality on this website. Because Computer Recycling is ordinarily closed on Saturdays, you will need special instructions to get into the building.

We will start at around 4pm and end around 8pm, but if you can only come later or have to leave earlier that's fine too.

Justin Filip will lead an interactive workshop on setting up Vagrant. He writes:

Have you ever heard or used the phrase “well, it worked on my machine”? Have you ever tried to replicate your production environment locally and found it to be incredibly difficult, hard to accurately reproduce or completely impossible? Are you trying to do anything at all on a Windows machine?

Vagrant is probably the answer to all of your problems. Whether you are developing by yourself, working with a team, or pushing to a very specific production environment, Vagrant can help you build repeatable, reliable virtual machines in Windows, Mac OS and Linux dev environments.

What to expect:

We will be using Vagrant to create a Ruby development environment that will allow us to create a sample Rails application running on a PostgreSQL database backend. We will touch on topics such as:

• box discovery and providers
• machine provisioning
• plugins
• deployment

No coding or Virtual Machine experience is required but it will help with understanding advanced concepts.

What to bring:

Bring your laptop (Windows, Mac, or Linux machines) with your favourite text editor and please pre-install the latest versions of the following for your operating system:

• Vagrant – https://www.vagrantup.com/downloads.html
• VirtualBox – https://www.virtualbox.org/wiki/Downloads

You will want a laptop that has virtualization extensions enabled. Plenty of RAM (8GB or more) would be helpful.

Colin Mills will give us an introduction to the C programming language. He writes:

C is the backbone of modern computing. Its a broad statement but I
believe it be true. With roots in almost every operating system on the
planet and having a rich forty year old history C still
stands. Providing both flexibility and simplicity C embodies the
world's first portable abstraction over hardware. Having an idea of
memory and lower level programming concepts helps us in all areas
of our computing lives. Come learn the one of the world's first
"higher level" programming from the basics.

Chris Irwin will discuss his adventures with webOS, the open-source tablet/TV/phone operating system you may have never heard of (but might very well use).

Kris Braun will discuss the work he did customizing OpenWRT images for his startup. He may cover topics related to lua, dnsmasq, iptables, and uhttpd.

University of Waterloo graduate student Nik Unger will tell us about his research. He is creating a state-of-the-art emulation platform that aims to emulate the entire Tor network at full scale. Tor is an open-source tool that helps users to stay anonymous online. He will discuss some of the challenges involved, his approach to the problem, why he chose Linux as a platform for it, and specific features of the Linux kernel that enable his work. He will also share some of this project's implementation details.

Unfortunately, the OpenWRT customization presentation is being postponed. It will be rescheduled. Stay tuned.

This month's meeting will consist of some shorter presentations:

• Bob Jonkman and Chris Craig will describe the technology and workflow for the incredibly useful WatCamp tech event calendar.
• Kirk Zurell will show us the Guile module he wrote for managing the key retention facilities built into the kernel (!).
• Peter Melse will demonstrate his adventures using a Raspberry Pi 2 as a car computer.
• Andrew Cant will tell us about the Indieweb movement.

This month will be a smorgasboard of short presentations. If you would like to contribute a presentation please contact us.

- John Kerr will show some screencasts he made, and teach us how to make our own.
- Bob Jonkman is organizing a keysigning party. (Instructions for participants)
- Bob B will demonstrate ZBackup.
- Tim Laurence will show us how to identify performance bottlenecks in servers.
- Andrew Cant will demonstrate the static Indyweb.
- Paul Nijjar will give an overview of VLANs: What they are, why they are useful, and how to use them. (Slides, Slide sources)

Chris Irwin lived a personal experiment to synchronize his mail, with the following goals:

• Access mail from the commandline
• Synchronize between hosts, with no information totally local
• Use standards
• Minimal annoyance day to day
• Synchronize with Android

To accomplish this he uses a stew of utilities and libraries: mutt, notmuch, Khard, Khal, Todoman, iSync/MBsync, vdirsyncer, git, CalDav-sync, CardDav-sync, OpenTasks, Baikal and DavMail.

Construction note: Victoria Street is closed between Charles and Weber streets. If you are coming from the West side of Kitchener-Waterloo, you will want to find an alternative route to the building. If you can get to Weber you should be okay.

Omar Atwa, who is a grade 8 student, created a Raspberry Pi Water Irrigation System for his school's Science Fair. The project incorporates a moisture sensor, an analog to digital converter, and a relay, all driven by a Raspberry Pi to keep soil moist for a plant. He will be walking us through the details of what he did, and how he did it.

Khalid Baheyeldin will demonstrate his new Raspberry Pi development kit, and how he got started:

• Where to buy a kit?
• Using NOOBS to install Raspbian Jessie
• How to turn the Pi into a music player and internet radio player, including controlling it on the command line, from a phone app, and from the web.
• Writing a Python weather forecast app, including a tiny built-in web server.

R. Brent Clements will continue his discussions and demonstrations of sound tools in Linux, including audio recording for music.

Due to the organizer being sick and having no stamina, we are deferring this session. Stay tuned to this space for rescheduling details.

Note: This may be the last refurbishing session for a while, so if you have been waiting to participate this is your chance.

Tim Laurence will lead an interactive tutorial on setting up and using Docker. If you have a laptop, you can bring it and follow along.

Tim has made Docker preparatory materials available at https://github.com/timdaman/docker-tutorial. He writes: "Tell people to be prepared or else. ;)" which probably means he is not going to make time at the beginning of the evening for people to get set up.
