Topic: Mentoring

Do you often fear being fired? Is your confidence level in the basement? Is it hard to admit your accomplishments? Do you always work to prove your worth to your peers? I do. All the time. A lot of people do. You are not alone. Studies even say that most people feel like an impostor at some point. Let's talk about what it looks like. Let's talk about the destructive toll it takes on our self-confidence and motivation. Let's talk about how to notice when it touches you or someone you know. When we recognize impostor syndrome, we can conquer it, and release ourselves to do joyful work.

Topic: Kernel

Using tools from the IO Visor Project, learn how to run JIT compiled C programs inside your kernel using the eBPF "in-kernel virtual machine".

Explore how to bend this kernel Swiss army knife to your will.

Topic: Embedded

This talk is not about solving broad, sweeping, Internet of Things-scale issues.  This is about approaching Things from the ground up; building interconnected thingies and doodads that will eventually comprise the armies of our future machine overlords.  

Internet of Thingies will delve into the physical making of devices which can be used to control systems or collect interesting data.  We will look at use cases, making, and using open source software to interact with Thingies.
