From cd59590c34c59e633633e867d43186c7c0b43dfd Mon Sep 17 00:00:00 2001 From: Garry Tan Date: Sat, 18 Apr 2026 11:57:58 +0800 Subject: [PATCH] =?UTF-8?q?feat:=20compute=20real=202013-vs-2026=20through?= =?UTF-8?q?put=20multiple=20(130.2=C3=97)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Ran scripts/garry-output-comparison.ts across all 15 public garrytan/* repos. Aggregated results into docs/throughput-2013-vs-2026.json and ran scripts/update-readme-throughput.ts to replace the README placeholder. 2013 public activity: 2 commits, 2,384 logical lines added across 1 week, in 1 repo (zurb-foundation-wysihtml5 upstream contribution). 2026 public activity: 279 commits, 310,484 logical lines added across 17 active weeks, in 3 repos (gbrain, gstack, resend_robot). Multiples (public repos only, apples-to-apples): - Logical SLOC: 130.2× - Commits per active week: 8.2× - Raw lines added: 134.4× Private work at both eras (2013 Bookface at YC, Posterous-era code, 2026 internal tools) is excluded from this comparison.
