Each published topic has at least eight eligible videos, an original introduction and direct links back to its videos.

14

AI Talks

Explore machine learning, generative AI and research talks that Hacker News readers return to across different discussions.

08

Startup Talks

Founder stories are most useful when they include the messy parts: product choices, failed assumptions, distribution problems and what changed after launch.

50

Programming Talks

These programming talks focus on ideas that remain useful after a framework falls out of fashion: language design, software architecture, abstraction, maintainability and the craft of building systems.

32

Computer Science Lectures

A collection of university lectures and technical explainers covering algorithms, computer architecture and core computer science ideas.

27

Tech Documentaries

Long-form documentaries can preserve the context that short tutorials leave out: the people, institutions and accidents behind modern technology.

51

Conference Talks

Conference stages produce far more video than anyone can reasonably watch.

16

Developer Career Talks

Career advice for engineers is often generic, so this collection focuses on talks and interviews that earned positive recommendations inside technical discussions.

13

Coding Interview Talks

Hiring and technical interviews sit awkwardly between software practice and performance under pressure.

16

Security Talks

Security becomes easier to understand when attacks, defenses and incentives are presented together.

09

Database Talks

Databases hide difficult tradeoffs behind familiar queries and APIs.

13

Distributed Systems Talks

Distributed systems talks are most valuable when they make failure modes and tradeoffs concrete.

24

Compiler Talks

Compilers sit where language design, runtime behavior and computer architecture meet.
