Why meditation and programming are a perfect match.

A practical guide to internationalization pitfalls in React. From tricky pluralization (especially in Czech) to parameter handling and translation key misuse, this talk shares lessons that go beyond basic i18n setup.

Why performance monitoring should be continuous—not occasional. This talk covers how to track FPS, CPU, and memory usage effectively and why it matters for building smooth applications.
