wroclove.rb 2025 lightning talk (opening with the Sugarhill Gang / 'Rapper's Delight' pizza-pies joke) on how to prepare a conference talk. Concrete tips: preparation is a ton of work but finite — a 30-minute talk at 100–120 words per minute (recommended for non-native speakers to sound smart) is ~3,600 words; discover your strengths via Gallup's CliftonStrengths 34 (the speaker's analytical/input/strategic themes carried his talk despite communication not being a top strength — pick a topic that matches your top themes); learn storytelling at Toastmasters, local Ruby user groups, or YouTube; practice in front of the mirror so you don't make weird moves; and take creatine — described as the best-tested supplement, improving short-term memory and cognitive performance under sleep deprivation. Encourages attendees to submit to more calls for papers because wider choice means better programming. References Pavo's earlier Drug meetup presentation about a different part of the same rewrite.
