Tech can change distribution of power. Online voting is usually developed onlyas 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.

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.

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'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).
