Michael Hitchens will discuss LMMS, a digital audio workstation application used to create sounds and music. He writes:

Learn how to make music with LMMS, the GPLv2 digital audio workstation!  Well maybe not how to compose music, but at least how to realize your musical endeavors in digital form. Michael Hitchens will guide you through the basics of how to navigate the interface, enter notes, use multiple built-in instruments, apply built-in effects, and to unleash your musical creations unto the world.

(Michael has also publish supplementary material on his blog.)

Rocco Commisso will show us how he uses Kritia and Blender to create illustrations and video game art. Rocco is a talented artist and educator, and will be taking us on an informal tour of what these tools do, and how artists can you them to express themselves.

John Kerr will tell us about Joplin, an open source note taking app that can be easily synchronized to cloud services. He writes:

Joplin is a Markdown based note taking application. You can have numerous notes in tabs.  Information can be hosted on dropbox to synchronize with all of your devices. This feature makes Joplin a reasonable personal Wiki substitute for OwnCloud or NextCloud. I create a calendar page that I find more useful than many calendar apps, mainly because I do not have multiple meetings on many days of the week.

Doug Moen will give an update on Curv, focusing on the new design of the programming language. Curv is a programming language for creating art through mathematics, focusing on 2d and 3d geometric modelling. He writes:

After 5 years of messing around with Curv, the limitations of the current  design and implementation are quite clear. It's time to redesign everything. This will be the 3rd major design for the language and its internals.

This meeting will be held on BigBlueButton: https://webconference.kwlug.org/room/kwlug .

Jason Eckert will give us a beginner-friendly introduction to the  fast, modern, secure, formally-verified, multi-platform and trendy VPN tunnelling software WireGuard.

Marc Pare from the local LibreWaterloo group will give us the inside scoop on some internal projects, and demonstrate how to read ODF files without the GUI.

Update: Alisa had to postpone her presentation, but we will reschedule.

Christian Snyder worked on a digital storytelling project for Reception House, a local refugee settlement agency. He developed a workflow to help new refugees share their stories on social media, and he turned to open source for help. Among the tools he recommended was OpenShot, the free software video. Christian will discuss the project and lead us through the technology decisions he made.

The PinePhone is a recently-released open hardware phone that runs mainstream Linux. Stephen Paul Weber owns one, and will share his experiences about it. Stephen also owns a Novena laptop, and may share his experiences with that as well.

This meeting will be held on BigBlueButton: https://webconference.kwlug.org/room/kwlug . There will be no passcode.

Mikalai Birukou will give us an update about his 3NWeb project. He writes:

There is no separate cybersphere, there is only life here. Online is real  life. Your digital rights are no different from everyday human rights.  Unfortunately, today most people live in a digital feudalism.

Unlike physical space that was here already, we've been creating digital realm. Disrespect towards users is not a technical phenomena, but it is made possible by certain architectural choices.                                                                       

3NWeb gives a practical architecture for spaces that users own, where it is safe to build one's life, the promised land.                                 

 

Raul Suarez decided to move to a minimalist desktop using  XMonad on Archlinux. He will tell us about his journey, how he is adapting to the desktop, and the applications he uses. Part of his journey involved switching from bash to fish, which he says he "should have done years ago."                                          

The meeting will be held on our BigBlueButton instance: https://webconference.kwlug.org/room/kwlug . There will be no passcode.

Mikalai was unable to present in September, so he will talk about his work in online voting systems this month. He writes:

Tech can change distribution of power. Online voting is usually developed only as a convenience for voters, but we can do more. I will present a design that shifts power to voters by letting every voter to count votes. My device counts votes, your device counts votes, and we the people come to consensus. 

Derek Steinmoeller will tell us about scripting and apps for Linux users. He writes:

In this talk, I'll introduce Python 3 to Linux users interested in building automation solutions and/or their own simple apps. We'll look at application areas both on the desktop and the Raspberry Pi.

The meeting will be held on our BigBlueButton instance: https://webconference.kwlug.org/room/kwlug . There will be no passcode.

Colin Knapp will demonstrate how he installs the fast, small, and modern VPN WireGuard on his devices.

Mikalai Birukou will tell us about his YAW-Hooks project, which creates transient credentials for use in scripts. He writes:

There are times when you want a process on one machine to do something on another.

The simplest and POLA (Principle of Least Authority) compliant approach would be to define a script/command, give it a url that may even lock arguments (POLA) passed to script/command, and generate credentials applicable only this url (POLA). Use creds to do precise curl-ing.                                     
                                                                              
Repo is at https://github.com/3nsoft/yaw-hooks .

Each year, the Free Software Foundation holds a conference in Boston. This year, some people in Kitchener-Waterloo are organizing a satellite event to be held at the Delta Hotel in Waterloo. They write:

We're excited to be hosting our own version of LibrePlanet, an annual conference hosted by the Free Software Foundation in Boston for free software enthusiasts and anyone who cares about the intersection of technology and social justice. LibrePlanet brings together software developers, law and policy experts, activists, students, and computer users to learn skills, celebrate free software accomplishments, and face challenges to software freedom. Newcomers are always welcome, and LibrePlanet 2020 will feature programming for all ages and experience levels. The theme for LibrePlanet 2020 is "Free the Future".

For the first time ever, all the great presentations of LibrePlanet are coming to Canada! Bringing in the main talks via live stream, with space for local hallway track and more, LibrePlanet Canada Satellite Edition is your chance to meet with like-minded participants and take in the event from Canada. For those in Southern Ontario who find travel to Boston just beyond their price range, or those in Canada or anywhere else who have difficulties with travel to the USA, this is the version of LibrePlanet for you.

Tickets have a suggested price ranging from $50 (for students/low-waged) to $250 (for those being sponsored by their companies). Pricing is flexible in that you can pay less (or more!) for tickets depending on your financial circumstances.

R. Brent Clements will give a beginner-friendly tutorial on Audacity.

Mikalai Birukou will tell us about the third leg of his journey in building out web infrastructure at scale. He writes:

I have talked about Docker and LXC out of my own experience. Now I've been Salt-ing the whole infrastructure ( https://docs.saltstack.com/en/latest/ ).

I'd love to share my own finite experience, findings, choices (not ideal, of course). I'd love to hear your comments, your perspective and your "war stories".

As usual, I'll talk from a perspective of doing it from ground up, the simple way possible (forever novice).

 

Tim Laurence will discuss his adventures with USB over IP.

In the second half of the talk we will have a roundtable-type Q&A. Bring your questions! Bring your answers!

John Steel will give a beginner-friendly introduction to SSL certificates and Public Key Infrastructure (PKI).
