Summary
A curated list of 23 Hacker News threads on topics every programmer should understand, humorously framed as “programmers should know a lot… apparently.” Topics cluster heavily around latency (4+ entries), memory, algorithms, and systems fundamentals.
一份精選的 23 個 Hacker News 討論串清單，涵蓋每個程式設計師應該了解的主題，以幽默的口吻呈現。主題大量集中在延遲（4+ 條目）、記憶體、演算法和系統基礎知識。
Key Points
- Topics covered: programming paradigms, SSDs, time (complexity), latency (4 entries), lockless concurrency, AWS costs, algorithms (2 entries), floating point, memory (2 entries), regular expressions, security, SEO, Vim, time complexities, optical fibre
- Format: pure HN thread links — the value is in the discussions, not the article itself
- Latency is heavily represented (4+ threads) — reflects the author’s view that latency understanding is underrated
Insights
The list’s redundancy (4+ latency entries) is itself informative: latency and performance intuition are pervasive gaps in developer knowledge that repeatedly surface in HN discussions. The list serves as a breadth checklist — if you haven’t read at least one HN thread on floating point, memory models, or lockless concurrency, these are high-leverage knowledge gaps to fill. The SEO entry is the only “business” topic, standing out among purely technical subjects.
