All of these presentations were built with <3 with Bespoke.js with the exception of "Introduction to Arch Linux" (which was written with <3 using LibreOffice Impress).

Introduction to Arch Linux

An introduction to Arch Linux - why it's awesome, how to use the tools that it provides, and how to interact with the community.

The presentation will roughly cover:

  • The Arch Way (basic philosophy of the distro, etc.)
  • A basic outline of the system installation procedure
  • How to use pacman, the PACkage MANager, and the AUR, the Arch User Repository (where you get software not in the official repos)
  • How to engage with the community/get help (and not get flamed)

Presented at LinuxFest Northwest 2014.

Just Do It: The Approachability of Free Software for Beginners

We all know that one of free software's greatest strengths is the ability to do whatever you're interested in, without asking for permission. But even though we all know, we don't talk about it that much, and in particular, we don't talk about the significance of what that strength means for those who are just beginning their programming careers.

"Just Do It - The Approachability of Free Software for Beginners" will put forth the idea that the only tools that are approachable for beginners while still leading to the ability to produce what we would call "high quality" software are all free software tools. It will talk about the ability of free and open source software to inspire curiosity and interest and the role of that curiosity in bringing new programmers into our community. Finally, it will explore some of the areas that this model fails in, and what we can do to fix it.

Presented at SeaGL 2015.

Available in slide form and source form.

I've written several longer presentations for workshops run at the Recurse Center.

Security design

How to design programs securely

Webapp security

How to secure webapps

Operational security

How to run a secure production environment

HTTPS deployment

Basics of HTTPS and how to deploy it

Cryptography basics

Basics of cryptographic protocol design + Community = ♥ is a promising project to create a federated social network. It was abandoned for a while, but its maintainer has recently started transferring governance and code maintenance to the community. Come to this talk to learn details about what is, why it's awesome, and the future plans for it.

This was originally a lightning talk dealing mostly with the community, but was expanded to a full session. The extra time was used to talk a little about the history of where comes from and its API.

Presented at LinuxFest Northwest 2016.

Available in slide form, source form, and on MediaGoblin and YouTube.

CryptoParty Seattle

CryptoParties are a global movement of people who get together to teach each other basic privacy tools, in order to ensure their right to privacy from spying eyes like Internet Service Providers, corporations like Google and Facebook, and the government (including the NSA!).

Participants will learn how to protect themselves against mass surveillance with technologies like:

  • Tor Browser Bundle
  • Tor Messenger
  • Signal

No prior experience is required.

Presented at TA3M Seattle's August 2014, June 2015, and December 2016 meetings. (The above description was written for the most recent event; earlier CryptoParties covered PGP, used Pidgin instead of Tor Messenger, and had different honorable mentions.)

All three versions available in slide form.

There are also a couple smaller/less interesting presentations written as 10-minute topic introductions for Seattle Academy's robotics program.

RobotC basics

Introductory presentation on RobotC (back when FTC used RobotC - thank god those days are over!).


An overview of sensors available in robotics. Also written during the NXT/RobotC days.
