_ OpenStreetMap in Vancouver

私の知り合いが、GPS Loggerを入手して遊び始めたとのこと。Vancouver でも近頃の oil 高騰で、車の使用頻度を下げて、べつの手段を使う事を検討しており、どうせ移動するならと移動するモチベーションをあげるべく、OpenStreetMap に参加して楽しもうという意図があるとのこと。(http://www.openstreetmap.org/?lat=49.221&lon=-123.01&zoom=11&layers=B00FTF) 日本はまだまだこれからですが、Vancouver は結構入力している人がいるみたいですね。

Description: The Spread messaging daemon
 Spread is a toolkit that provides a high performance messaging
 service that is resilient to faults across external or internal
 networks. Spread functions as a unified message bus for distributed
 applications, and provides highly tuned application-level multicast
 and group communication support. Spread services range from reliable
 message passing to fully ordered messages with delivery guarantees,
 even in case of computer failures and network partitions. Spread is
 designed to encapsulate the challenging aspects of asynchronous
 networks and enable the construction of scalable distributed
 applications, allowing application builders to focus on the
 differentiating components of their application.
