Presentations

Xavier Rene-Corail
Audience: Developer
Topic: Security

For the first time in software's history, AI assistants distill the collective knowledge of developers, making coding easier, but what about more secure? This is crucial as our research shows that there exists 1 AppSec professional for every 100 software developers.

Joe Conway
Audience: Intermediate
Topic: PostgreSQL

If a PostgreSQL database resides on, for example, a RHEL 7 system with glibc version 2.17, and the operating system (OS) is upgraded to RHEL 8 with glibc version 2.28, the majority of indexes built on collatable columns will be broken. This talk will walk through examples of the types of breakage that can occur, the proposed solution at a high level, and a demonstration of the solution in action.

Guinevere Saenger
Audience: Everyone
Topic: Cloud Native

When you've run the same Docker command in your CLI for the fifteen thousandth time, you know you have some automation to do. In this talk we will learn how to avoid creating the dreaded `scripts/util.sh` and use Docker's Go libraries instead to build, run, and update our Docker environments.

Ryan Trinkle
Topic: NixCon

Add state of the art continuous integration (CI) to your project. With Nix, CI not only enhances code quality, it also provides automatic binary caching, speeding up development and deployment. We'll cover the basics, gotchas, and tips and tricks for CI in Nix-based projects, and then help you apply them to your own project. Mentors will be available to help work through any issues you encounter. Our goal is for everyone to leave the workshop with a fully set up CI process in production.

Tatiana Krupenya
Audience: Beginner
Topic: General

When we hear about open-source contribution we usually imagine code contribution. In DBeaver we have developed open-source applications for more than 10 years and we have contributors around the world. Are they all developers? Of course not. Can we say that code contribution is the most valuable among other types? Also not. Let's take a look how else you can help your favourite open source project.

 

Caleb Schoepp, Justin Pflueger
Audience: Beginner

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.

Aaron Prisk
Topic: Ubucon

Erik Mondrian
Audience: Everyone
Topic: FOSS @ HOME

As both a longtime Resident of Second Life and someone who is deeply fascinated by the concept of "place" more generally, I wanted to see this world (or parts of it) in a more comprehensive way than the platform's software is able to show. To that end, I've been creating large-scale terrain models of various areas, using a combination of LSL, Python, and Blender.

In this presentation I will go into more detail about the process involved, touching on some of the challenges I've encountered while hopefully also giving attendees a better look at Blender's incredibly powerful Python API.

Julien Riou
Audience: Intermediate
Topic: PostgreSQL

Performing database schema changes on a live system is challenging because it often involves high level of locks leading to downtime. It becomes harder and harder when the number of databases to manage raise continuously. At OVHcloud, we used to manage such changes approximately. In this talk, you will discover our feedback on how we have reduced efforts, time and human errors by automating databases schema migrations using git, code reviews, CI/CD, migration tools and Ansible at the OVHcloud scale.

Reid Vandewiele
Audience: Everyone
Topic: Cloud Native

The presentation will allow the audience to improve their Kubernetes Resource Management skills and ultimately enhance their overall productivity, with a clear call to action to avoid performance degradation, avoid outages, provide better multi-tenancy, and ultimately reduce cloud costs.
