Hello, friends! After 10(!) years of #AdventOfCode, I've made some changes to preserve my sanity: there will be 12 days of puzzles each December (still starting Dec 1) and there is no longer a global leaderboard. Read more:

House Republicans Want To Doxx Wikipedia Editors Over Bogus ‘Bias’ Complaints
Congress has absolutely zero constitutional authority to investigate a private website for its editorial decisions. Zero. None. This is First Amendment 101. Yet House Oversight Committee Chairman James Comer and Cybersecurity Subcommittee Chairwoman Nancy Mace have decided otherwise. In a letter to Wikimedia Foundation CEO Maryana Iskander, these two Republicans are demanding that Wikipedia hand over editor identities, internal communications, and arbitration records because some studies suggest there might be bias in Wikipedia articles about Israel-Palestine issues.

The Supreme Court’s Shadow Docket Has Become A Lawless, Explanation-Free Rubber Stamp For Trump’s Authoritarian Agenda
When Joe Biden wanted the Department of Education to forgive student loans, the Supreme Court shut him down hard. The Court spent pages in Biden v. Nebraska explaining why the Department lacked authority under the HEROES Act, demanding "clear congressional authorization" for such a significant policy change. But when Donald Trump wants to dismantle the entire Department of Education without any congressional authorization?

We ran a randomized controlled trial to see how much AI coding tools speed up experienced open-source developers.
The results surprised us: Developers thought they were 20% faster with AI tools, but they were actually 19% slower when they had access to AI than when they didn't.
