San Francisco on the eve of JavaOne 2010. Various preparations are underway in the city. Posters and banners, even on the sidewalks, mark the largest Java show on the planet. One of the true eye catchers this year is the closing down of Mason St for the full length of a block. Traffic is diverted, to allow for ‘The Zone’ (a lounge for developers and architects, OTN Live and various exhibitions and activities around Java. The preparations have just started, the road has been closed and the construction of the tent has started. See the pictures below to get an impression.
