Past Meetings

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."

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.

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.

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).
