Let’s face it—most incident retrospectives are about as useful as a code comment that says 'fix this later'. They’re packed with finger-pointing, hindsight bias, and imaginary scenarios where everyone did everything perfectly. In this talk, we’ll explore a blame-aware, human-centered approach to incident management that turns problems into learning opportunities. With a focus on quality observability, practical service catalogs, and the essential role of customer support, this session offers actionable strategies for building resilience and fostering real, lasting improvements.
Replit.com is website used by millions of users to collaboratively create software with their teammates and now with Replit’s AI Agent. Replit uses Nix to manage the underlying development environments. When building a Nix environment, downloading files from cache.nixos.org can take a long time, and many files would be duplicated across Repls. In this talk, I will show how Replit uses Nix local-overlay-stores to manage Nix caching, as well as our new cache disk architecture using tvix-store.
Kickoff this year's UbuCon @ SCaLE 22x and layout the events for the day.
Bring all your pressing Ubuntu questions for a lively and friendly Q&A with long time Ubuntu Members and SCaLe community organizers, Nathan Haines and Richard Gaskin.
This focused technical session provides MySQL DBAs and developers with essential knowledge for understanding PostgreSQL's key differences and similarities. The session prioritizes practical, high-impact distinctions that affect day-to-day operations and development.
In this talk, I will be discussing the Universal Blue Project. The Universal Blue project builds custom bootable container images via OCI/Docker containers. The project publishes a diverse set of base images and tooling for users to develop their own custom images. We will be explain how the project builds images and why we feel this model is the future of Linux.
As AI adoption accelerates across industries, organizations are seeking infrastructure solutions that meet the unique demands of AI workloads without locking them into proprietary ecosystems. OpenInfra solutions are emerging as a powerful alternative to traditional platforms, enabling scalable, flexible, and cost-efficient AI infrastructure. This expert-led panel will delve into how open source technologies are addressing the infrastructure needs of AI while fostering collaboration and reducing reliance on proprietary systems.
Git is a tool used by millions every day and a core part of any software development workflow. But how does it really work? How does Git actually transfer data to the server? How does it track changes and stores all the data and versions?
In this talk, we’ll take you on a journey through Git’s internals and protocols, sharing what we’ve learned about how Git transfers data over HTTPS, optimizes for storage and speed, and what it’s like to manage a Git server yourself.
UpSCALE is a set of lightening talks held at SCALE, in the style of Ignite presentations. Speakers will get 5 minutes to enlighten the audience. Slides will auto-advance while chosen speakers deliver their message, a brief story of open source deliciousness. The format makes for a fast paced, fun event for participants and audience. Please join us as members of the Free and Open Source community do their best to beat the clock and get their ideas out! Want to be an UpSCaLE speaker?
