Jira Is Turing-Complete

Nicolas Seriot (Hacker News): Engineering folklore holds that Jira (Atlassian’s project-tracking tool) is Turing-complete. Existing claims point vaguely at automation features without exhibiting a reduction. This article supplies a proof, with setup instructions and execution trace. […] Minsky proved this model Turing-complete (1967). Exhibiting it in Jira’s automation language therefore establishes the reduction. Here is […]
