The Gathering / Software Freedom First Saturday (May)

Software Freedom First Saturday: The Gathering
Start your month off right, by building software freedom with your technical friends.
Featuring:

1. Alan Robertson - Keeping secrets and voting machines
2. Jeff Haemer - A Bit of Bash: How Does a Shell Work?
3. Open Mic: Bust out your show-and-tell

Bring:

1. A machine, preferably Linux
2. A question or an idea
3. Maybe a show and tell

Topics:
1. Alan Robertson -This talk is about why secrets are hard to secure on a computer, and how this difficulty affects computer mediated elections.

• A demonstration of managing physical secrets using a lock box
• What kinds of data needs to be secret in an election
• Why is it hard to secure any secret data on a computer
• How secret data is stored on election computers
• How might one do a better job of securing critical secrets, and corresponding difficulties

2. Jeff Haemer - A Bit of Bash: How Does a Shell Work?
One way to understand shells better is to write one. I'll do that in a live demo. To keep it simple, I'll write that shell in bash.
"Really???" Really. "No way!" Way.
Come watch me face plant.
Here are the slides, with a link to exercises at the end.

There is a value for value ask of most events, this month is:
Pay what we ask: $16 https://paypal.me/sfs303/16
Or, pay what you choose: pwyc@sofree.us
[ If this your first time, show up, see if you like it, and decide our value then. No one will be turned away for lack of payment. ]
This is a hybrid event, in-person preferred.
When you register, you'll be asked whether you're planning to participate in-person or online. We need to know so we can plan seats and snacks.
We use Big Blue Button (it's like Zoom) for our online classroom:
