Baz/Bazaar, Upgrading Ruby Libraries

Meeting Date

Doug Moen will introduce his new project Baz. Baz is new open source project with the goal of publishing desktop apps to every desktop in the world as easily as we access webapps.

Bazaar will be an associated, decentralized app store embedded in the world wide web. 

Doug will introduce his plans for the project, and solicit helpers to help him make it a reality.

Andrew Cant will tell us about his journeys in updating Ruby libraries. He writes:

It is time for Andrew Cant to update his slightly neglected Ruby gems. What choices will he need to make? Who knows!

Some of the details will be Ruby specific, but should also apply to maintaining any open source repository. Andrew will try to give you ideas for updating your own libraries.

ESPHome, Linux USB Persistence

Meeting Date

Tim Laurence will spread some of his enthusiasm about home automation and ESPHome, which allows you to specify firmware using YAML files.

Cris Waurechen will discuss his attempts to create a bootable USB Linux distro with persistence. He writes:

This presentation will cover my attempt to make a persistent linux install on a USB drive. Attempts were made with both Manjaro and Mint, but Mint was unsuccessful so far. The presentation will focus on Manjaro but will touch on the problems while attempting to make a persistent Mint USB drive. I will include some warnings and observations from this experiment, a walk through of how to create your own persistent USB drive and stream a demonstration of a PC booting from persistent USB storage.

Unit Testing, Kubernetes Roundtable

Meeting Date

Andrew Cant will give us an overview of unit testing, with a focus on Ruby tools.

We will hold a collective demo/roundtable/Q&A session about Kubernetes. Apparently it is mandatory that we refer to this as the "pod cast". To kick things off, Mikalai Birukou will describe his own situation. He writes:

Docker Swarm sorta goes away and those of us using it have to move production pieces to something that is more widely used. And it is Kubernetes. We'll approach it from noob-ish perspective. I'll talk. I may answer some questions, but I'll also ask audience. If you k8s-ed, come to help.

Update Andrew points us to the projects and as two projects containing some of his testing examples.
