When AWS has a major outage, what actually happens behind the scenes? Ben Hartshorne, a principal engineer at Honeycomb, joins Corey Quinn to discuss a recent AWS outage and how they kept customer data safe even when their systems couldn't fully work. Ben explains why building services that expect things to break is the only way to survive these outages. Ben also shares how Honeycomb used its own tools to cut their AWS Lambda costs in half by tracking five different things in a spreadsheet and making small changes to all of them.

About Ben Hartshorne:

Ben has spent much of his career setting up monitoring systems for startups and now is thrilled to help the industry see a better way. He is always eager to find the right graph to understand a service and will look for every excuse to include a whiteboard in the discussion.

R. Tyler Croy, a principal engineer at Scribd, joins Corey Quinn to explain what happens when simple tasks cost $100,000. Checking if files are damaged? $100K. Using newer S3 tools? Way too expensive. Normal solutions don't work anymore. Tyler shares how with this much data, you can't just throw money at the problem, but rather you have to engineer your way out.

About R. Tyler:

R. Tyler Croy leads infrastructure architecture at Scribd and has been an open source developer for over 14 years. His work spans the FreeBSD, Python, Ruby, Puppet, Jenkins, and Delta Lake communities. Under his leadership, Scribd’s Infrastructure Engineering team built Delta Lake for Rust to support a wide variety of high performance data processing systems. That experience led to Tyler developing the next big iteration of storage architecture to power large-scale fulltext compute challenges facing the organization.

From why they use simple technology to how they run thousands of separate installations for customers, Jeremy explains what happens when you care more about making a good product than explosive growth.

André Arko, CEO of Spinel Cooperative and longtime Bundler maintainer, joins Corey Quinn to introduce RV, a new Ruby tool that installs Ruby in one second instead of 10-40 minutes by using precompiled binaries. Inspired by Python's UV, RV aims to simplify Ruby dependency management without the complexity of older tools like RVM and rbenv. They talk about why Ruby isn't actually dead, Apple's problem with shipping a five-year-old end-of-life Ruby in macOS, and the challenges of writing dependency managers in the language they manage. André also shares how he transitioned from a struggling nonprofit model to a cooperative that charges companies for expertise, proving that open source maintainers can build sustainable businesses without relying on donations.
