HN Time Capsule !$1AHackerNewstimecapsuleprojectthatpullstheHNfrontpagefromexactly10yearsago,analyzesarticlesanddiscussionsusinganLLMtoevaluatepresciencewiththebenefitofhindsight,andgeneratesanHTMLreport.Alsosee$1 for more context. What it does 1. Fetches the HN frontpage from 10 years ago (e.g., https://news.ycombinator.com/front?day=2015-12-09 ) 2. For each article, fetches the original article content and all HN comments 3. Generates prompts asking an LLM to analyze what happened with hindsight 4. Parses LLM responses to extract grades for each commenter 5. Renders an HTM…
