Presentations
WebAssembly has come a long way in the past few years in the cloud native ecosystem. Real-world applications are possible, and powerful, and better yet it works great with existing technologies. This talk is a demo-heavy and practical showcase of WebAssembly's strengths and limitations when it comes to running a highly distributed application.
PostgreSQL's WAL is one of the core points of PostgreSQL, and used in many areas: Backup, replication, etc.
In this talk, I will mention about everything about WAL that a PostgreSQL DBA must know.
In this talk, we will describe our situation, how we ended up with a serverless application by accident. We talk about where we started, our use case, and how it turns out leveraging FaaS and the Code-Engine Serverless platform.
Arrays are an essential part of software development. Among modern databases, however, only PostgreSQL has dedicated datatypes, functions, and indexes built to efficiently work with arrays. In fact, I think arrays are a hidden superpower of PostgreSQL, fully utilized as a data type, usable in pl/pgSQL, and essential for a myriad of built-in functions to process data more efficiently.
Come learn about how powerful and useful arrays can be in your daily PostgreSQL development.
As a long time Kubernetes user, it can be real confusing what all of this hype around WebAssembly (Wasm) means for the future. Join Taylor, a long-time Kubernetes community member and contributor, as he talks about Wasm; how and why it should be used; and what you can do to experiment with it.
Businesses all over the world are using Kubernetes to run the applications they need. But why, what does Kubernetes really do? As an enterprise-grade open source technology designed for scale, it can be hard to find ways to use Kubernetes to understand it ourselves. So let's explore it with something a little more approachable - cookies! Through this fun, hand-illustrated analogy, you'll learn about the value Kubernetes provides as a container orchestrator - running applications at scale, and how it does this valuable work with tools like pods, deployments, services, and scheduling!
Cloud Native; Edge Native. There is only a word of difference, and yet, a world of differences separates those two concepts. The goal of this presentation is to explore what Cloud Native applications and Edge Native applications have in common and what makes Edge Native applications distinct. You will also learn about various runtimes to deploy your edge native applications. While Kubernetes is part of the list, it is far from the only option at your disposal. You will survey some open-source alternatives, which include WebAssembly.
What is Nix? What is NixOS? You've heard of it, but what does it actually do? The answer is everything. Using Nix, we can reproduce anything, anywhere, any time. Bringing ancient HAM radio packages back from the dead, cross compilation to any foreign architecture, including bootstrapping the compiler itself, isolating packages from each other at runtime, building OCI images, building embedded Linux system images, deployments, you name it. Nix can do it. Some have even taken to calling Nix "the art of containers without containers".
Free, CAD, BIM, FEM... what is it and why might I care?
3D Printing is just one of the simplest things FreeCAD can be used for. With commercial products like Fusion 360 limiting features for free personal use, OpenSource software like FreeCAD become even more important to know and use.
Come and see some of what it can do. Add it to your arsenal of skills. Learn what it is and how to get started. Learn what makes it different from Blender, OpenSCAD and others. Learn about features like what 'parametric' means, and how you can use Python with it.
PostgreSQL 15 was released in the autumn of 2022, and as usual comes with many new and improved features. This talk will go through some of the more popular of those features, with a short explanation of each.
