Hoisting, phantoms and doppelgängers - demystifying the spooky world of NPM node_modules and how to eradicate its darkness with PNPM 

Physicists say black holes are the heaviest things in the universe, but surely they've never seen a truly monstrous node_modules folder. In this talk, we'll venture into the eerie underworld of NPM node_modules, where scary forces like hoisting, phantoms, and doppelgängers can haunt your projects and keep you up at night. But don't worry - there's a way out! I'll show you how switching to package managers like PNPM can help banish these spooky beings. Plus, I'll share real-life learnings (and a few battle scars) from migrating a monorepo from NPM-like setup to PNPM - so you can make this journey without losing your sanity.

Blazor WebAssembly - a new approach to web application architecture 

Blazor WebAssembly is a technology that combines the power of C#, JS, and WebAssembly into a single framework for building modern web applications. By leveraging WebAssembly, Blazor introduces a new way to handle client-side logic, enabling developers to use C# directly in the browser while seamlessly integrating with JavaScript. This unique approach has implications not only for architecture and maintainability but also for application performance, especially in scenarios involving computationally intensive tasks. In this talk, we'll explore how Blazor WebAssembly works, its potential to change front-end development, and how it blends these technologies to create efficient, scalable, and maintainable applications.

No Vercel? No problem! 

Discover how to deploy your projects on a VPS using Nix and Kubernetes. Learn to leverage NixOS for declarative setup and Kubernetes for ease of deployments, gaining full control and avoiding vendor lock-in. It's a perfect setup if you want to have a cost-effective and flexible environment. And even if you want to stick to the cloud, you should still try it at least once to deeply understand the layers of the deployment stack.

I am switching to Go, and so is TypeScript (Lightning Talk ⚡️) 

Much to everyone's surprise, it was recently revealed that the TypeScript team at Microsoft had been secretly evaluating multiple programming languages to rewrite the TypeScript compiler in. The best language for that task turned out to be Go.

Should we cancel cloud? (Lightning Talk ⚡️) 

Cloud platforms promised simplicity and scalability, but have they delivered—or just locked us into complexity and rising costs? In this lightning talk, we'll question whether small projects really need the overhead of hyperscale infrastructure, and explore how a humble VPS can often do the job better, cheaper, and faster. Let's challenge the cloud status quo—and bring back developer sanity.

Straighty introduction (Lightning Talk ⚡️) 

Spending the day hunched over a keyboard is a problem most JavaScript developers know too well, and the typical posture-correcting gadgets often end up weakening the muscles they're supposed to support. This talk introduces Straighty - a lightweight macOS app built as a hobby project that uses your webcam to watch your posture and nudges you with a notification whenever you start to slouch.
