AI-Powered Algorithmic Composition and Sound Design

Siarhei Lunski Speaker
Jan 14, 2026

The exponential growth of AI tools has already changed the way people create music and experiment with sound. Professional musicians, composers and regular people already use these tools to express themselves. And how about programmers? Can we bring coding and engineering directly into the creative process with AI as our programming partner? This talk dives into algorithmic composition and sound design where LLMs generate live audio synthesis code, giving you direct control over how sound works at the fundamental level. We'll explore the power of programmatic music creation with LLMs and discover how this approach opens up endless experimentation possibilities and transforms live performance from playing pre-made tracks to creating entirely new sonic experiences on stage.

Write Once, Test Everywhere: Cross-Platform Testing for React Native

Szymon Chmal React Native expert @ Callstack
Dec 9, 2025

Testing React Native apps has always been a trade-off between speed and realism. Jest is fast, familiar, and excellent for unit tests, but it runs in Node.js and relies on mocks for native modules. End-to-end frameworks offer realism, but at the cost of complex setup, ongoing maintenance, and slower pipelines. Enter React Native Harness, a new testing framework that lets you run Jest-style tests directly on real devices and simulators, with full access to native modules and no mocks by default.

The Illusion of Immortality: Temporal's Magic for Reliable Workflows

Tomasz Nurkiewicz Author, Trainer, Conference Speaker
Nov 12, 2025

If you are orchestrating microservices, use queues, webhooks, cron jobs, run periodic processes, distribute work or elect leader, call lambda functions, have background processes... you are most likely implementing a workflow in disguise. Explore the concept that nearly all non-trivial code can be viewed as a workflow. This talk introduces Temporal, an open-source workflow orchestration platform, which allows developers to write workflows as if their servers were running indefinitely. Examine Temporal's ability to facilitate workflows that span extended periods, from milliseconds to years, without compromising reliability. The presentation will highlight Temporal's built-in features for resiliency, automatic retries, and load balancing, which significantly reduce the complexity of distributed system development. I aim to demonstrate how Temporal's approach to workflow management can significantly enhance the reliability and scalability of distributed systems, while also addressing the practical considerations of its implementation. Examples and live coding in Node.js environment.

Javascript demons and how to find them

Maciej Papiewski Tech Lead at LUX MED
Nov 12, 2025

I will go over Javascript drawbacks and quirks with the most substantial impact, and explain where they started. These will include inherent security flaws of both the language and the ecosystem, syntax/runtime quirks that cause the most needless errors. Then I will present how entire companies started just to mitigate some of these flaws.

My First Few Months with Lynx.js

Łukasz Chludziński Speaker
Nov 12, 2025

So you've heard of React Native, Flutter, maybe even SwiftUI — but what about Lynx.js, the new UI framework coming out of Bytedance (yep, the company behind TikTok)? Over the past few months, I've been diving into Lynx.js, building real apps with it, and learning where it shines… and where it still makes you want to scream into a pillow. In this talk, I'll share: • What Lynx.js actually is, and why Bytedance/TikTok are betting big on it • The developer experience (good, bad, and "wait, what just happened?") • How it handles cross-platform UI at massive scale • Lessons I learned as a newcomer — so you don't make the same mistakes Whether you're curious about the next wave of front-end frameworks, or just want to know what TikTok is running under the hood, you'll leave with a solid picture of Lynx.js and a few laughs along the way.
