Thursday A Quick Introduction to Nix 9:30 to 10:30 - Room 101 Tom Bereknyei NixCon This session will contain an introduction to Nix for the uninitiated. You will leave with an understanding of the basics and, perhaps, the beginning of a lifetime of love for Nix. We will cover installation, use of the CLI, and the basics of the Nix language. Create a First AI Program with TypeScript and Serverless WebAssembly 10:00 to 13:00 - Ballroom A Caleb Schoepp, Justin Pflueger Kubernetes Community Day This workshop starts with the open source Spin tool for building WebAssembly-based serverless apps. We'll build a simple Hello World app in TypeScript (advanced participants can opt for Rust or Python instead). Then we'll turn our simple Hello World into a first foray into AI inferencing using a large language model (LLM). This is an excellent opportunity to try out AI with only a dozen or so lines of code. A beginners guide into the heart of systemd 10:00 to 13:00 - Room 211 Alvaro Leiva, Anita Zhang Workshops systemd (with lowercase S and D) remains up until this day, both one of the most critical pieces of a system, and the least understood one. This workshop is designed to touch upon the beginner features of systemd and explain how you can use systemd to solve common problems, including some that you didn't even know you had. What problems do you ask? You’ll have to come and see. PostgreSQL for Oracle DBA's 10:00 to 11:00 - Ballroom H Thuymy Tran, Wanda He PostgreSQL Learn the architectural concepts, similarities and differences between the PostgreSQL engine and Oracle Database. Innovating Software Delivery Harnessing Generative AI in DevOps and DevSecOps 10:00 to 13:00 - Room 209 John Willis, Dave Nielsen, Alice Chen Workshops This workshop explores the integration and impact of generative AI tools in DevOps and DevSecOps.

The State of Partitioning 10:00 to 11:00 - Ballroom G Keith Fiske PostgreSQL Declarative partitioning is now available in all supported versions of PostgreSQL. As with all major features in PostgreSQL it started off with basic capabilities and has been slowly advancing on those to become a well supported part of the architecture. However, there are still some significant hurdles to overcome. This talk will review where partitioning as been, where it's at now, and where it still has to go. Workshop: Hands-on Kubernetes 10:00 to 13:00 - Ballroom B Tammer Saleh, Maziar Tamadon Kubernetes Community Day Kubernetes is a transformative tool, but its Lego-brick approach and vast tooling landscape bring massive complexity. This hands-on workshop will guide you through the golden path of running applications on Kubernetes and then explore the complexities needed to productionalize those workloads. You’ll learn not only what Kubernetes is, but also when it’s appropriate, and when it can be a velocitydestroying distraction for your team. Insight out of CHAOSS: Community Data Analysis Tool Workshop 10:00 to 13:00 - Ballroom F Cali Dolfi, James Kunstle Workshops Are you a community manager looking for insights into your community using open source tools? Are you a data scientist looking to build custom visualizations in Python or with the Dash framework? This workshop is for you!

Creating a community for the next generation 10:15 to 11:00 - Ballroom C Aaron Prisk Ubucon More information coming soon Open Source is Not Just Code 11:00 to 12:00 - Ballroom C Ubucon In open source projects, you find a variety of contributors. Some have been around for decades, others have been around for months. Some are paid for their work, others do it out of the kindness of their heart. Some people are just starting out in the tech industry and need a place of belonging, others have been in the tech industry for decades. Given these facts, it is important that everyone works well together, when the opportunity to accomplish collaborative work presents itself. Managing your Userland with Home-Manager 11:00 to 12:00 - Room 101 NixCon Unleash the full potential of your user environment with the "Portable Userlands with Home-Manager" workshop. Discover how to use Home-Manager to create reproducible, portable configurations for your applications and tools. Ideal for Nix users who want to personalize and efficiently manage their desktop across multiple systems. For all Nix(OS) users who are not afraid of writing configuration files in Nix language.

Graph Walking in PostgreSQL for fun and possible profit 11:15 to 12:15 - Ballroom G Mark Bracher PostgreSQL A few jobs ago my colleagues and I were faced with the task of correlating and deduping incoming data from a myriad of sources.  The most promising approach was a graph in which each node represents a piece of data and an edge represents a relationship between two pieces of data.  We tried a test set of ~10M nodes in multiple available graph engines, all OOMed on our queries.  So we built it ourselves in Postgres.  This is the story of how we did it, and some of what we learned along the way. VACUUM: From your head down to your shoes 11:15 to 12:15 - Ballroom H Devrim Gunduz PostgreSQL VACUUM is an essential part of PostgreSQL. In this talk, I will go through it, starting from basics to the internals. MVCC: The basics Data snapshots VACUUM VACUUM processing FREEZE VACUUM tuning VACUUM FULL Ubuntu Core Desktop - Immutable, secure, reliable 12:00 to 13:00 - Ballroom C Ken VanDine Ubucon There's an obvious trend towards immutable systems, and for good reasons.

In this talk we'll provide an introduction to Ubuntu Core Desktop, why it's important, who will benefit, and provide a glimpse into the future. Welcome to the Kwaai Personal AI Summit 12:00 to 12:15 - Room 212 Matt Small Kwaai Summit Welcome to the Kwaai Personal AI Summit Personal Empowerment and Agency at Scale 12:15 to 12:30 - Room 212 Doc Searls Kwaai Summit According to Sam Altman, that's what OpenAI promises. Problem is, it can't deliver, because OpenAI is for AI in 2024 what IBM was for personal computers in 1974: still a mainframe company. As individuals, we know more about what we need from personal AI than any of the AI giants of today can guess at. And that's what Doc will talk about. The AI Accelerated Personalized Computing Revolution 12:30 to 12:45 - Room 212 Pankaj Kedia Kwaai Summit We have had a front row seat as computing has evolved over the last 3 decades – from the desktop PCs to laptop PCs, from tablets to smartphones, and from single-function devices to a plethora of smart devices and wearables. With AI going pervasive on a global scale, we are at the cusp of the next personalized computing revolution – where use cases will truly be optimized for 1:1 experiences.

Wait! What's going on inside my database? 12:30 to 13:30 - Ballroom G Jeremy Schneider PostgreSQL PostgreSQL 9.6 introduced wait events and PostgreSQL 10 progressed them, but what are they? What do they mean? How do I find them and how do I make them go away? Wait events are one of the most significant advancements in observability for PostgreSQL databases; their usefulness is unparalleled in troubleshooting performance. This talk will go into all that and more as we perform a flyover of the field of database performance engineering in general, and then dive deep to explore the world of PostgreSQL wait events specifically. How to Ride Elephants Safely 12:30 to 13:30 - Ballroom H Richard Yen PostgreSQL Every so often, one may be called upon to perform the tasks of a database administrator, especially in cases where application performance seems to be affected by the database.  This talk will give non-DBAs an insight into how the world's most powerful open-source database works, and the kind of tools and features that are readily available for people who unexpectedly find themselves in the DBA pilot's seat.  Topics covered will include query tuning, monitoring, indexing, and a basic run-down of some configurables to help you know what options are at your disposal What is Kwaai? 12:45 to 13:00 - Room 212 Reza Rassool Kwaai Summit Learn about the Kwaai project's mission and values. What is Personal AI? 13:00 to 13:15 - Room 212 Kwaai Summit Learn all about Personal AI. Personal AI Demos and Use Cases 13:15 to 13:30 - Room 212 Matt Small Kwaai Summit Personal AI Demos and Use Cases Basic NixOS Modules 13:30 to 14:30 - Room 101 Daniel Baker NixCon We've all been there. We start playing with our NixOS config and see a cool blog post about modularizing your config. That would be so cool! ... wait how do modules work? The documentation is pretty sparse. And those "beginner" blog posts about modules are so beginner friendly. So we are going to play with and build our own modules. But we aren't going to build packages; our output is going to be plaintext. We are going to see and feel how each of our options influences the output.

Panel Q&A 13:30 to 14:00 - Room 212 Kwaai Summit Panel Q&A Workshop: Rancher Rodeo - Deploying and managing Kubernetes 14:00 to 17:45 - Ballroom F Auston Ivison, Brian Six Sponsored Join us for an in-depth, live workshop designed to give DevOps and IT teams the hands-on skills they need to deploy and manage Kubernetes everywhere with SUSE Rancher. During this hands-on workshop, SUSE will provide an introduction to Rancher, Docker, and Kubernetes and then walk through the steps for deploying a Kubernetes cluster with Rancher. Attendees should have a basic working knowledge of Docker. Stop using kubectl, and use Git instead! - Hands-on GitOps workshop using Argo CD and Helm 14:00 to 17:00 - Ballroom A Nicholas Morey, Justin Marquis, Christian Hernandez Kubernetes Community Day Kubernetes is a declarative-first platform where manifests written in YAML describe what resources should exist in a cluster. Many new users will use imperative processes, running `kubectl apply`, to define and change the state of their cluster. This approach is known as the “push” model, and while it works initially, it does not scale as more users adopt the platform. Actors outside of the cluster should not be able to make changes directly. GitOps practices provide a declarative approach to defining and managing the state of Kubernetes. Charming your home network with Juju and Ubuntu Core 14:00 to 15:00 - Ballroom C Callahan Kovacs Ubucon Jellyfin? PiHole? Home Assistant? Wouldn't it be nice to manage them all in one place, migrate them to new hardware, and have peace of mind on security, updates, and stability? Well now you can, with Juju!

CentOS Classroom and Packaging Workshop 14:00 to 17:00 - Room 211 Shaun McCance, Carl George Workshops Learn how CentOS works and how you can make it work better for you. CentOS is the open source, community operating system that releases just ahead of RHEL. The CentOS project also provides a space for people to build technologies on top of the operating system for specific use cases, from clouds to cars. We will present an overview of the CentOS ecosystem, followed by a workshop teaching you how to make your own packages. SCION Internet Architecture Workshop 14:00 to 17:00 - Room 209 John Studarus, Robert Hernandez Workshops SCION (Scalability, Control, and Isolation on Next-Generation Networks) is the first clean-slate Internet architecture designed to fundamentally solve many security issues of today's Internet through route control, failure isolation, and explicit trust information. This tutorial will give an overview of the SCION architecture, its open-source implementation, and provide hands-on exercises. Attendees will run a full-fledged AS within a virtual machine, connect it to the global research testbed to explore SCION's security features. AI and Trust 14:15 to 14:30 - Room 212 Bruce Schneier Kwaai Summit Trusting a friend and trusting a service are fundamentally different, and current AI systems are poised to exploit that difference. We will think of them as friends when they are actually services, and confidents when they will be actually collecting data behind our backs. Government is how we create social trust in our society, which requires regulating this potentially intimate technology. Everything you probably never wanted to know about NULLs 14:30 to 15:30 - Ballroom H Christopher Travers PostgreSQL This presentation focuses on the finer points of NULLs in PostgreSQL as well as corner cases.  We will start with an introduction to NULLs and three-valued logic and a quick overview of the common NULL traps that everyone tends to fall for.  Then we will dive in to corner cases and what they tell us about NULL handling in general.  We will also cover a few cases where proper understanding of NULL handling makes some problems much easier. Patroni Deployment Patterns 14:30 to 15:30 - Ballroom G Michael Banck PostgreSQL This talk will present a brief overview of Patroni and then discuss various deployment patterns (and possible issues with them) that we encountered while working with customers to implement PostgreSQL HA. In particular, it will discuss the following: synchronous standbys and/or read replicas, standby clusters for multi-region/availability zone replication, client fail-over possibilities and issues/solutions with DCS problems interfering with Patroni.

Consumer Protection in AI 14:30 to 14:45 - Room 212 Kwaai Summit Consumer Protection in Ai Panel Q&A 14:45 to 15:15 - Room 212 Kwaai Summit Kwaai Tools Advisory Panel Continuous Integration Hands-On 15:00 to 16:00 - Room 101 Ryan Trinkle NixCon Add state of the art continuous integration (CI) to your project.

Advancements in Machine Reasoning 15:15 to 15:45 - Room 212 Khai Pham Kwaai Summit Advancements in Machine Reasoning pg_hint_plan - get the right plan without surprises 15:45 to 16:45 - Ballroom G Franck Pachot PostgreSQL I frequently use pg_hint_plan to gain insights into the query planner choices made by the optimizer, and sometimes to work around issues that arise in production. However, hinting is often a complex task, requiring multiple hints to fix an exact plan. We will explore practical examples of how to use pg_hint_plan in a predictable manner, while also gaining a better understanding of access paths, join methods, and execution plan interpretation. PostgreSQL - memory management internals 15:45 to 16:45 - Ballroom H Krishnakumar Ravi PostgreSQL PostgreSQL uses memory for several purposes such as caching data (buffer cache), supporting user scenarios like query processing (work mem), as managed resource for internal use (memory context) and more. We will look at how each of these memory semantics are configured and used. Further we will dig into the internals of how PostgreSQL implements them accompanied with demos, tool usage and preview of work in progress.
