🏆 Featured talks of the week

Here are our top recommendations this week.

1. "Data: The Land DevOps Forgot • Michael Nygard • GOTO 2024" ⸱ +1k views ⸱ 11 Jul 2025 ⸱ 00h 33m 27s

   tldw: In this talk, Michael Nygard explores how traditional DevOps practices left data management in the lurch. He explains the challenges faced by Nubank, where massive analytics are still operating in an outdated way. The talk introduces the concept of a data mesh. You'll learn how to transition to data mesh, its benefits, and potential pitfalls.

2. "Functional Programming in 40 Minutes • Russ Olsen • GOTO 2024" ⸱ +3k views ⸱ 09 Jul 2025 ⸱ 00h 31m 40s

   tldw: This is a beginner-friendly talk to the core concepts of FP: immutable data structures and pure functions. The speaker also discusses how languages like Clojure implement these principles, making functional programming not just an academic concept but a practical tool for developers.

3. "React Compiler Internals" ⸱ +1k views ⸱ 14 Jul 2025 ⸱ 00h 21m 08s

   tldw: Introduced in 2024, React Compiler automatically optimizes React code to improve performance by memorizing components, sparing developers from manual work like adding useMemo hooks. The speaker explains how the compiler transforms code into an optimized form, covering processes like Abstract Syntax Tree (AST) transformation and effect analysis. You’ll learn about performance benefits and challenges, all while avoiding the dreaded task of writing complex code.

4. "Mastering Resilient Java API Design: From Principles to Practice | Steve Poole (EN)" ⸱ +100 views ⸱ 13 Jul 2025 ⸱ 00h 44m 28s

   tldw: You'll learn how to avoid common pitfalls in API evolution and how semantic versioning alone may not prevent breaking changes. The talk also introduces modern Java capabilities like sealed classes which help in creating resilient and robus APIs.

5. "A (deep) dive into (shallow) immutability: Valhalla and beyond | Marat Akhin" ⸱ +3k views ⸱ 14 Jul 2025 ⸱ 00h 38m 06s

   tldw: The speaker delves into current features related to immutability, what's missing, and the possibilities with Project Valhalla. You'll learn about new immutable value classes, how they are checked by the compiler, and the ergonomic ways to update immutable data through copy semantics.
