rysiek writes "Last weekend marked the first Startup Weekend in Poland. Three days, about 100 developers and designers, 20 mentors, forming 30+ teams. The big winner — CityRace.me — will be launching soon, with a few others close on its heels. Most hackteresting project — Nest of Worlds (conceived by the Warsaw Hackerspace people) — has it all: Game of Life on hexes, with sound in pure JS (needs Firefox 4, but still awesome). There is also a lengthy summary of the network setup and problems for the network admins among you. Ralph Talmont also offers a more general write-up. Disclaimer: I was the network guy."
