The Hardest Tarball

Comments on “The Hardest Tarball”

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

Harry Stoppels, writing on his blog, describes a single crafted tar archive built with one GNU tar command that extracts in eight different ways depending on the tool used.

Read the original at stoppels.ch. 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. 49 of 51 with a score of 0.56. The panel rated it highest on new information (0.92) and technical depth (0.90), lowest on significance (0.39). The judges disagreed most on significance (spread 0.45), so the story is marked contested. Placed No. 49, No. 48 by score alone: the eighth Programming & dev tools story of the day (−0.080). The placement terms move stories; they are not part of the score.

AI judgeJudge 2claude-haiku-5-5
Deeply technical, well-substantiated survey of tar parser inconsistencies with reproducible test suite; relevant to parser and security-minded builders, but niche in scope and modest significance.
AI judgeJudge 3gpt-5.6-luna
A reproducible tar edge case is tested across many real implementations, revealing interoperability and potential parsing hazards. It is technically deep and practically useful to systems developers, though its field-wide significance is moderate.

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.
