Design and implementation of a real-time telephony AI receptionist

CTO - StratusTalk

Disappointed by per-minute pricing and the risks of sending HIPAA data to public APIs, StratusTalk decided to build their own AI receptionist. By embedding the agent directly into their Asterisk/FreePBX offering, they gave it the same tools a human receptionist uses: call transfers, intercom, outbound dialing, and more.  In this talk, Jeff will walk you through their design decisions, their Kubernetes-based solution, and show you live demos of it in action.

Desperately seeking Susan

CEO - Eurice / Callibri

At the request of a translation company commissioned by the French government under immigration law, we developed a system that can find a translator among the 125 languages offered in less than 5 minutes, involving Asterisk, an AGI server, AMI connection, an IVR, and other tools.

Deterministically Built Containers or: How I Learned to Stop Worrying and Love Nix

Software Engineer - Flox

You’re probably familiar with containers and OCI images, and you’ve probably heard of Nix—usually from that somebody who really, really likes it. This talk explains how containerd assembles containers from OCI images, then contrasts that with how Nix builds reproducible artifacts that can be composed into a complete execution environment. With that foundation, we’ll walk through a few practical ways to use Nix-built components as container filesystems in Kubernetes—ranging from assembling a rootfs from a closure to generating OCI images to running Nix-based environments directly in containers. The goal is to give attendees a clear mental model of both systems and the spectrum of techniques that connect them.

Developing Open Source Hardware Solutions for FRC

- FIRST Robotics Team 2404

Robotics teams are often short of cash, and off-the-shelf hardware solutions are expensive. In 2025 I designed and built a printed circuit board meant to control addressable LED strips whilst utilizing the CAN protocol for communication, which we could use on our competition robot, and which other robotics teams could make or have made for use on their own robots. My primary goal was to create a controller that was considerably less expensive than the other available options while retaining many of the same capabilities and being completely open source.

My presentation will act as a Do-It-Yourself guide to developing open source hardware solutions, following the path I took. I will go through the process of identifying a need for a piece of hardware, determining desired capabilities, designing and testing a breadboard prototype, designing and testing an initial design, identifying key areas of improvement, and then redesigning. I will finish by describing the process of writing code for hardware, and open sourcing the hardware solution(s) and code. 

DevOps is a Foreign Language (or Why There Are No Junior SREs)

Developer Advocate - Altinity

DevOps has a notoriously steep learning curve. Getting started in the field can feel like being dropped in a foreign country without the ability to understand *anything* about the language. 

A language is more than just the syntax and semantic rules of the words themselves. It also encompasses the shared culture of the speakers. With the proliferation of programming languages as well as the deeply held cultural beliefs of the community, it's easy to see that learning DevOps is like trying to learn a foreign language.

I will review five foundational hypotheses from the field of Second Language Acquisition and relate these hypotheses back to the world of DevOps. DevOps practitioners, trainers, tool builders, and learners should all come away with useful insights to apply to their practice. 

Did VS Code Quietly Become a Go-To Postgres Tool?

Director, Global Postgres Practice - Datavail

It's no secret that VS Code from Microsoft is a popular code editor. It's free, it's loaded with shortcuts and themes, and you can extend it with the vast plugin network. Some of those extensions are written and maintained by Microsoft, and they've created a few that Postgres administrators will want to know about. With these extensions VS Code becomes more than a code editor, it's a comprehensive database management environment.

The PostgreSQL Extension

The official PostgreSQL extension allows you to connect to databases, manage objects, write queries, export data, and more! We'll explore how it brings database development directly into your editor:

- Connecting to instances and managing credentials
- Browsing schemas, objects, and functions (and getting Intellisense, too!)
- Writing and executing queries
- Exporting results

GitHub Copilot: AI-Enabled Chat Partner

GitHub Copilot brings AI into your workflow, with Postgres-specific suggestions and integrations. It connects to your database and enables an @pgsql chat partner to bounce ideas off of, and even issue database altering commands to if you're truly bold.  We'll learn:

- How Copilot learns your schema and suggests SQL
- Using the agent to help write queries, look for optimizations, and troubleshoot issues
- Security considerations and best practices for safe Production usage

Oracle to Azure Schema Conversion

Oracle to Azure Schema Conversion is an exciting new extension that will radically cut the time it takes to perform Oracle to Postgres migrations. It's powered by Azure OpenAI to provide intelligent transformation capabilities for complex schema operations. This segment covers:

- Analyzing an Oracle schema and suggesting Postgres equivalents
- AI-driven conversion of Oracle native PL/SQL, packages, sequences, etc.
- How the tool flags potential problem areas, and how to test your results

Lastly, we'll talk about why these tools matter, and how their introduction signals a broader shift in database tooling. This talk is ideal for PostgreSQL developers and DBAs who want to streamline their workflows, teams evaluating database tooling options, and anyone curious about how AI is transforming database development. Whether you're a VS Code veteran or have never considered it for database work, you'll leave with practical techniques you can apply immediately.

Distributed Embeddings At Scale: Processing 10+ million rows per day with Ray, GPUs, and Qdrant

Principal Software Engineer - ZEFR

In this talk, we’ll describe a production-grade NLP pipeline that processes millions of pieces of social media content across TikTok, YouTube, and Instagram using Ray and GPU acceleration.

Do You Need An AI Assistant With MySQL?

Dave Stokes
Technology Evangelist - Percona

Artificial Intelligence is an overhyped distraction, except for what it can do for you when using MySQL. AI is strong in he pattern matching area, which means it is great with SQL syntax and examining DDL metadata. This session will cover basic prompting, using AI to repair or augment existing queries, and developing new schemas. And you can write queries in English (or French, or German, or Italian) instead of SQL, saving you a lot of time determining which tables need to be joined where. SO, yes, you do need an AI Assistant to get the maximum out of your MySQL instances, and this session will show you how to do it.

dRAG Race: Benchmarking Open Source Vector Databases

“dRAG Race: Benchmarking Open Source Vector Databases” presents the findings of Kwaai’s intern-led Vector DB Performance project, now accepted for publication in the Journal for Big Data and AI. A cross‑functional cohort of data science and engineering interns—guided by a PhD AI‑robotics advisor and program coordinator—designed and ran a rigorous benchmark of seven open source vector databases under realistic RAG workloads, from corpus design and chunking through automated multi‑run experiments and visual analysis.
 

Drasi- A New Take on Change-Driven Architectures

Principal Software Engineer - Microsoft

Building systems that respond reliably to specific changes in distributed data is harder than it should be. This session introduces Drasi, a CNCF Sandbox project that simplifies change-driven design by codifying continuous query and reaction patterns. We’ll show how Drasi helps developers declare which data changes matter and automatically trigger the right downstream updates- no polling loops or custom glue code required.

Beyond everyday scenarios like keeping services and dashboards in sync, Drasi also supports AI-driven workloads where fresh data is critical. From updating embeddings to refreshing model inputs, Drasi ensures AI systems stay aligned with the latest state of the world.

You will learn the fundamentals of change-driven architecture, see Drasi in action, and walk away with practical patterns you can apply in your own distributed or AI-powered systems.

Eight Steps to Bullet-Proof Database Disaster Recovery.

Principle Software Engineer - pgEdge

Disks fail, RAM runs short, software breaks, and human error strikes, and data loss follows fast. This talk presents a direct recovery path built on concrete steps used in production: detect corruption through log checks and checksum validation, stop the service to contain further damage, restore from backups that pass verification, use point in time recovery to reach a clean state, extract readable tables when backups fall short, keep pg_resetwal as a last resort when no clean recovery remains, and strengthen the cluster with routine checksums, tested backups, WAL archiving, and replicas that support failover. The session focuses on reliable commands, clear failure patterns, and practical actions applied without guesswork.

Enhancing TPM security in the Linux Kernel

Partner Architect - Microsoft

Recent security updates to Linux, such as the new Systemd Unified Kernel Image rely on the discrete or firmware integrated TPM (Trusted Platform Module) to verify boot and release secrets securely. However, there are many known attacks against the TPM chip itself. We will discuss the newly upstreamed Linux Kernel TPM security patches, which not only provide a basis for securely communicating with the TPM but also provide a novel defences against a wide variety of TPM based attacks by using a unique (to Linux) null key scheme. This talk will cover what TPM based attacks are (including interposer attacks), how the Trusted Computing Group expects you to tell you're talking to a real TPM and how you can communicate with it securely and use its policy statements to govern key use and release. We will then move on to how the new Linux Kernel patches extend this and can be leveraged to validate the TPM on every boot and continually monitoring it for any TPM interposer substitutions in real time.  The new TPM trust verification tools are available under LGPL as ancillary tools in the upser space openssl tpm engine project.

 

Enterprises Play Dirty

CEO - Percona

From Red Hat to MongoDB, major vendors are increasingly adopting tactics designed to protect market power, limit competition, and restrict user freedom. This talk examines the strategies behind these moves and explores how they affect the broader open source ecosystem and the communities that rely on it.

We will discuss recent examples, the motivations driving these decisions, and the long-term risks posed to innovation, collaboration, and software freedom. Attendees will leave with a clearer understanding of the dynamics at play - and what the open source community can do to remain resilient.

Exploring Observability with MCP Servers

Senior Developer Advocate - Grafana Labs

You may have heard of the pillars of observability: metrics, logs, traces, and, depending on who you ask, profiles. As systems grow in complexity, correlating these signals for rapid incident detection, root cause analysis, and performance optimization still demands knowing specialized query languages and complex toolchains, even with OpenTelemetry.

Model Context Protocol (MCP) servers give assistants and tools a secure, standard way to work with your telemetry using natural language; this session introduces MCP and demonstrates exploring real observability data with Grafana MCP, while showing how the same approach applies to other MCP compatible tools or custom servers.

In this talk, we will dive into how these plugins work with the CloudNativePG Project in Kubernetes and walk through the creation and deployment of Postgres clusters with a custom plugin. By the end of the presentation, attendees will have a foundational understanding of how to use CloudNativePG along with CNPG-I plugins to deploy and expand their Postgres database solutions in Kubernetes.

Extreme Home Labbing: Building Large Scale Computing with Small Scale Budgets

What happens when you’re a volunteer-run academic event with almost no budget, but need to support thousands of concurrent users? We decided to embrace the home-lab mindset and scale it to the extreme. In this talk, we’ll share how we transformed the home lab mindset into competition-grade infrastructure powering events like WRCCDC, PRCCDC, many others. Using second hand hardware and resources, we’ll walk through our migration from VMware and a SAN to an entirely open-source stack built on Proxmox and TrueNAS, and how we replaced Active Directory with authentik + LDAP to eliminate licensing and increase flexibility. Along the way, we’ll cover the planning, hardware challenges, licensing challenges, design tradeoffs, training, and scalability lessons learned while running production infrastructure in a purely volunteer environment. If you are an educator and trying to string together a learning space for students or if you’ve ever wondered how far you can stretch open-source tools this is the talk for you.

Fast Code, Fragile Culture

Executive Coach and Speaker - TGL Advisory

AI and modern development tools have dramatically increased the speed at which technology is built. But as organizations optimize for efficiency, organizational behavior research shows they also shape what gets rewarded, who gets recognized, and which people remain engaged over time.

This session applies an organizational behavior lens to tech companies and product teams, examining how metrics, incentives, and default recognition practices influence motivation and psychological safety. It explores why critical non-code work often becomes invisible and how burnout and disengagement emerge as systems outcomes rather than individual failures.

Attendees will leave with practical frameworks to redesign recognition and contribution systems so culture can scale as effectively as the code.
