Algorithms & data structures Videos Recommended on Hacker News (60)
Algorithms & data structures is one of the 150 topics Hacker News readers organize their video recommendations around. These 60 videos each earned real recommendations in real HN threads between 2009 and 2026 — 191 recommendations in total — and they're ranked by how many separate months the community kept coming back to them, not by view count.
Algorithms and data structures: sorting, graphs, hash tables, trees, dynamic programming, competitive programming, MIT 6.006, algorithm analysis, Big-O, clever algorithms.
Why HN keeps sending people here — on CppCon 2017: Matt Kulukundis “Designing a Fast, Efficient, Cache-friendly Hash Table, Step by Step”: “Excellent talk which explains the concepts really clearly and concisely.” — an HN commenter, 2026.
