Spring is usually well known from Java developers. It started as a tiny open-source library in 2004 and quickly became one of the de-facto standards of Java applications. SpringSource, the company behind Spring, was acquired by VMware in 2009. Michael Isvy will first introduce the primary use of the Spring framework: Dependency Injection and Aspect Oriented Programming. We will then have a talk about Professional Open Source in general in order to figure out "how can companies make profit while giving away their product for free". Then contributor, organizer and already famous for attending a BLUG Tuesday last year, Pingooo will tell us more about COSCUP, the Conference for Open Source Coders, Users and Promoters, largest of the kind and community run in Taiwan. While some of us attended the 2010 edition which was co-hosted with GNOME.Asia Pingooo will explain us how it started, how the Taiwanese community manages to run it every year and constantly find new blood to mix with the old one to constantly grow the event to what it has become today. This year event is happening on August 20 and 21 and while registration is already full, we are confident that attending BLUG members can exchange a few beers against black market registration passes!本月9日（2011年8月9日）的BLUG活动上OpenParty的老朋友Michael Isvy会给大家带来Spring的话题，有兴趣的朋友请安排时间参加。活动的地点离平常OpenParty的活动地点不远。
