3 judges. Scored by all three judges. Only the day’s top stories get the claim check. How far stories are checked

AWS has renewed its sponsorship of cache.nixos.org, the public binary cache that serves prebuilt packages for NixOS and the Nix package manager, covering hosting costs for another year after first stepping in during 2023.

Read the original at nixos.org. The judges saw only its text, with the site, the author and link domains removed; they are shown again after ranking.

Why it ranked

No. 152 of 155 with a score of 0.55. The panel rated it highest on new information (0.83) and technical depth (0.80), lowest on audience breadth (0.52).

AI judgeJudge 2claude-haiku-5-5
Technical, detailed engineering write-up on Nix binary cache infrastructure and its sponsorship; substantive and practical for infra builders, but niche in audience and mostly a renewal announcement with modest new information.
AI judgeJudge 3gpt-5.6-luna
Detailed firsthand infrastructure account with concrete scale, architecture, reproducibility, storage, CDN, CI, and operational tradeoffs. Highly useful to systems builders, though focused on the Nix ecosystem and partly serves as an AWS/Flox sponsorship acknowledgment.

Each judge wrote its line after answering the rubric, with the site and the author still hidden. Every answer behind this is in the table under Score.
