Not investment advice. Muhabbit scores how much a story may matter, not which way to trade.

The 40C3 conference has launched halfnarp, a web-based scheduling helper that lets attendees select the talks they want to watch and submit their preferences to reduce timetable conflicts. The tool displays correlations between events, with darker shading indicating stronger overlaps, and now supports swipe navigation on mobile devices. Users can consult an FAQ and blog post for guidance, and report issues to erdgeist@ccc.de. The app matters because personal schedule conflicts are a persistent pain point at large multi-track conferences, and a lightweight preference-submission tool could ease crowding and missed sessions. What to watch next is whether organizers publish aggregated preference data or use it to adjust room allocations and repeat sessions.
