Louis Antonopoulos's wroclove.rb 2026 talk framed as an Indiana Jones parody (originally 'Indiana Jones and the Raptors of the Lost Arc', renamed for legal reasons). Opens with thoughtbot gem marketing (factory_bot, factory_bot_rails, and new gems Top Secret, Top Secret LLM, and Michelle) and a running joke where the audience shouts encouragement in their native languages every time the speaker drinks water. Core content: a Ractor primer covering the experimental warning (silenced via Warning[:experimental] = false), the send/receive/take pattern, multiple Ractors as 'archaeologists on a bus', Ractor.select, streaming Ractors with yield, conditional Ractors using a case statement, and a pipeline of excavator→cleaner→cataloger Ractors. Also covers the non-sharable-object error and mitigations (freeze, Ractor.make_shareable). Second half: decrypting five rotating substitution ciphers — whose plaintexts are quotes from a Matz interview — in 60 seconds. The solution uses English-letter-frequency seeding, quadgram scoring against a 389,000-line table, greedy letter-swapping with simulated-annealing-style 'chill' (accepting worse swaps early, tightening near the end). Single-thread fails; single-thread + 'freeze ray' (one rotation per 5s) fails; Ractors alone fail; Ractors + freeze ray succeed. The breakthroughs were (1) giving each Ractor a different starting key and (2) an increasingly aggressive cooling strategy per Ractor. Live demo succeeds after several attempts; final keystone reveal turns out to be the Ractor experimental warning itself. Closes with three thoughts: Ractors still experimental in Ruby 4.0 (hopefully not in 4.1), learning cryptography with an LLM was fun, and gratitude to the Ruby community. Q&A covers fire-and-forget Ractors for desktop GUIs, practical limits on Ractor count, terminal font-size tricks, and the inspiration for Ractors (audience reveals: Erlang).
