Julia Evans - On kubernetes scheduler bugs, TCP performance regressions and debugging tips - #2

Julia Evans runs a programming zines business, called Wizard Zines

Listen to the Software Misadventures Podcast on Apple, Spotify or watch us on YouTube.

Julia Evans runs a programming zines business, called Wizard Zines, where she creates comics about various programming concepts. She has been creating zines, when she was still a software engineer at Stripe. Her zines are extremely approachable and highly educational. In addition to creating zines, Julia is a prolific blogger and has around 500 posts on her blog at jvns.ca. Her blogs are another great source to learn about fundamental programming concepts. 

We had a lot of fun speaking with Julia for this episode. We discuss two bugs she came across at Stripe. We talk about how she identified and fixed a bug in Kubernetes Scheduler and how her understanding of TCP helped her fix a performance regression. We also cover other topics like blogging, zines, debugging and learning new things.

Show Notes:

• Why you should understand (a little) about TCP

• How does the Kubernetes scheduler work?

• So you want to be a wizard

• Linux debugging tools you’ll love

• Networking! ACK!

• Let’s learn tcpdump!

• Spying on your programs with strace

• Julia on Twitter

• Julia on LinkedIn

• Wizard Zines (Julia’s Programming Zines company)
