QubesOS: Desperately Securing The Desktop

QubesOS is an security-based operating system that isolates every application using virtualization. This is similar to how your phone creates a sandbox for each application you run but QubesOS isolates your email client from your PDF viewer, for example, using a hypervisor. It's an attempt to answer the question "How do I secure my desktop if I don't trust the hardware?" This talk will cover how QubesOS works, what security it provides, and lessons learned from using it for the past few years.


Join us for the Global Day of Coderetreat ( on November 17th! Never done a Coderetreat before? That's OK! We love having new people join us! Why join? Deliberate practice. If you enjoy writing software and want to get better at it, a Coderetreat is a great way to collaboratively improve. Oh, and breakfast and lunch will be provided.

What will you be doing?
You'll pair program Conway's Game of Life in short intervals. At the end of each interval, we'll delete our code, hold a brief retrospective, and find a new partner to do the next iteration with. During the event, facilitators will introduce new constraints to push your creativity and collaboration.

What do you need?
0. You've read
1. The whole day. If you show up considerably late, you're going to be lost.
2. A computer with a web browser that you're OK with someone else using with you. Preferably, have a unit testing tool installed. works well if you do not.
3. Some programming experience. If you've never written loops and conditionals before, you're not going to have a good time.

How many people can sign up?
For now, we're limiting the count to 20. If we get a wait list, we'll try to open more slots. Since space is limited, please only join if you know you can make it. If you need to bring an interpreter, mention it in the comments or send a message to the organizers.

Still have questions or just want to chat? You can find George on Slack (go to for an invite) and Twitter as @geow4.
