AI agents didn&amp;rsquo;t replace human collaboration — they amplified individual speed, shifting the bottleneck to coordination and integration. Vibe coding works for UIs and exploration; spec-driven approaches win at integration boundaries. The architectural lesson: humans own the interfaces, agents own the interiors. Participants estimated 3 days = 3 months of normal elapsed time, though that compresses prototyping time, not production delivery.&lt;/div>

&lt;p>Last week I spent three days in Lisbon at an AI hack day focused on audio. Seven teams, each building an individual capability, all working toward a combined product at the end. The scope was defined upfront. The teams competed for the best performance of their individual piece while building toward a shared vision. That mix of competition and collaboration created an energy I haven&amp;rsquo;t seen in traditional hackathons. The observations below aren&amp;rsquo;t specific to audio — they apply to any AI-assisted hack day where multiple teams build toward a shared goal.&lt;/p></description></item><item><title>Hackathon Gamification: A Real-Time Leaderboard You Can Deploy in 5 Minutes</title><link>https://schristoph.online/blog/hackathon-in-a-hackathon/?utm=rss-feed</link><pubDate>Thu, 07 May 2026 00:00:00 +0000</pubDate><guid>https://schristoph.online/blog/hackathon-in-a-hackathon/</guid><description>&lt;h2 id="lisbon-6-am-rising-sun">Lisbon, 6 AM, Rising Sun&lt;/h2>

&lt;p>Three days in Lisbon. Not for sightseeing, though the city makes that hard to resist. I&amp;rsquo;m here for an AI hackathon — teams building an AI-driven radio station from scratch. The kind of challenge where you start with nothing and ship something that plays audio by the end.&lt;/p></description></item></channel></rss>
