1. Tempest vs Tempest: two games, two decades, line-by-line
2. Treetops glow during storms, finally caught on film
3. Alberta startup sells 1990s tractors with zero electronics
4. How AWS reduced Lambda cold starts from seconds to 200μs
5. Show HN submissions tripled and look the same now
6. Are books actually more expensive than 1960?
