Tutorial: Take Control of Git: Beyond the Basics - Kim Schlesinger, Contentful & Kyle Coberly, Urban Sky

Wednesday June 25, 2025 11:00am - 12:35pm MDT

Bluebird Ballroom 3A

You can commit, pull, and push—but do you truly understand Git? Does it feel more like a fragile system you tiptoe around than a tool that empowers your workflow? If navigating your repository makes you hesitant, it's time to go beyond the basics and build real confidence.

In this hands-on workshop, you’ll learn to:

1. Navigate with confidence: Jump between commits without fear using Reflog, ensuring you never lose your place.
2. Refine your workflow: Embrace the safety of version control with resets to commit first and edit later.
3. Keep your best work: Shape your commit history with checkout file and interactive rebase to express your intent clearly.

Version control isn’t just a safety net—it’s a tool that amplifies your impact as an engineer. Equip yourself with the professional’s toolkit and make Git work for you!

Note: this is an interactive workshop, so please bring your computer with a terminal application installed and ready to go.

Billy and Eddie's Declassified Git Survival Guide - Billy Lynch, Chainguard & Eddie Zaneski, Defense Unicorns

Wednesday June 25, 2025 2:10pm - 2:50pm MDT

Bluebird Ballroom 3A

Have you ever botched your git repo so badly that you needed to delete it and reclone it? You're not alone!

This talk dives into the dark side of Git - exploring common disasters like accidental force-pushes, tangled merge conflicts, unrelenting rebases, and the dreaded detached HEAD. We'll look at how and why these situations arise, exploring the underlying Git mechanics that got us into the situation and how we can undo or resolve these problems.

You'll come away from this talk with a greater understanding of Git internals, and the knowledge and tools necessary to rescue yourself from any Git workflow gone awry!

Effortlessly Build, Run, Secure, and Manage Traffic for a Generative AI Application From Scratch - Lin Sun, solo.io

Wednesday June 25, 2025 3:05pm - 3:45pm MDT

Bluebird Ballroom 3A

Generative AI (GenAI) is ushering in a new era of human innovation, but building your own GenAI application can feel overwhelming. Which Large Language Model (LLM) should you choose? Should you incorporate Retrieval-Augmented Generation (RAG)? How can you ensure your application runs securely and efficiently on Kubernetes, with robust observability and debugging? And how do you manage API calls and control costs for external LLMs?

This demo-driven session will guide you step by step through building, running, securing, and managing traffic for a GenAI application from scratch. Starting with a native setup, we’ll then transition to Kubernetes, simplifying the entire process. You’ll learn how to enhance your application with domain-specific knowledge using RAG and leverage cloud-native tools like Kubernetes, Prometheus, Kiali, Istio, and the Kubernetes Gateway API to run your application securely and effectively.
