After 25 years in tech it’s hard not to coast. Adriana has come from writing word docs for the ops team to deploy software, through Devops, and now has a focus on OTel and Kubernetes. How do we get more people from 100 to 400 levels and why is there no content in between? And why we need junior engineers to make our senior engineers better.

Disaster recovery is more than automation and infrastructure. There's a lot that goes into your services and some of those things can't be defined as code or automated. When was the last time you restored your database from a backup? How do you use least privileged access when your region changes and how do you even know you're having a disaster. Seth has a lot of experience and a ton of good insights in this episode.

Railway wanted to build a better cloud so they started on Google Cloud and ended up building datacenters. Through the burden of success, they figured out there was a lot of things they had to learn and build themselves if they wanted to offer the best cloud experience they could. Jake tells us how they accomplished the move in 9 months, why the built their own orchestrator, and what they’re working on next.

You can't grow in technology without learning new things. But sometimes those new things are actually old things. We talk with Scott about a wide range of interests about software, video games, 3D printing, and food. If you want to know why junior engineers are important for your teams you need to listen.

What exactly is an LLM doing and why do you need to learn so many new terms? Steve Pousty is here to explain that most of those new terms are things you already know. It’s not new technology, it’s new words to describe technologies applied in a new field. We have a wild, ADHD roller coaster looping through embeddings, vectors, RAG, and LLMs. Make sure to keep your hands and arms inside the pod for this one.

Bluesky has been on a roller coaster of growth for over a year. From the early days of figuring out a new distributed social protocol—AT protocol—to actually building it and inviting 30 million of their closest friends. Not only has the site gone through tremendous growth, the team has been optimizing, re-architecting, and adding features the entire time.
Jaz is a software engineer focused on the infrastructure at Bluesky, and they share how they achieved exponential growth without exponential costs. We cover some of the key components of the protocol and how that affects the architecture.
There’s some amazing advice from the trenches we know you’ll enjoy.

Retirement is about the journey, not the destination. For Kelsey Hightower, it’s been an epic journey. On our debut episode of the Fork Around and Find Out Podcast (and much to Autumn’s elation), Kelsey joins us to run down his illustrious career that spans a quarter of a century.
Known for authenticity, Kelsey was on the frontlines of Kubernetes advocacy in the tool’s humble beginnings. Because of his time at Google, we get the inside scoop on why the company seems to enjoy killing off some of its most popular products. You’ll also hear his thoughts on why curiosity is essential to tech and why the industry needs to embrace problem solvers. We also get into the absurd state of the world, the moments that caused Kelsey to finally quit Twitter, and why he’s happy to embrace Bluesky.
Kelsey is not just someone who cares. He’s a genuine human being who’s invested in the future of the industry. We can’t wait for you to check out this conversation, because we know you’ll love it!
