6:30pm — Doors open, food, networking

7:00pm — TBA

7:15pm — Jackie Luo: Collaborative Debugging

If you've ever written code with other people, you've probably had to fix bugs with other people—and sometimes that’s the hardest part. When your logs have expired, you can't reproduce the issue, and you've tested five different hypotheses, maybe it's time to give someone else a shot. But what's the best way to do that? I'll talk about the workflow I use to collaboratively debug issues without repeating work or losing progress and why it makes sense.

7:45pm — Sid Shanker: Running User-Provided Code

In this talk, I'll be discussing some of the challenges I encountered building RubyProctor (, a website for rapidly developing RuboCop rules. Come learn about how to build a service that executes code provided by users safely! I'll be covering security practices in both Ruby and Docker that I used to prevent malicious users from doing destructive things to both my application and server.

8:15-9:00pm — More hanging out and talking to nice people


Jackie Luo is a software engineer who worked previously at Nylas, a startup building email, calendar, and contact APIs. She starts at Square on the Caviar team next month. In her own time, she loves cooking, photography, and writing. She spends too much time on Twitter (@jackiehluo).

Sid Shanker is a software engineer currently working at Fin, who loves Ruby and has been working in it for 5 years. He also dabbles in Go on the side and is interested in databases and distributed systems. When he's not coding, you could probably find him playing tennis, reading, or continuing his quest to find the best bimbimbap in San Francisco.
