Contest

The 2014 Intel Level Up Game Developer Contest is open...NOW!

I'm super excited for another season of Level Up.  You'll notice a subtle but important change in the name from "Intel Level Up Game DEMO Contest" to "Intel Level Up Game DEVELOPER Contest".  We recieved feedback last year that the term "demo" carries more weight amongst would be participants - many people thought we were looking for polished, consumer ready "demos".  What we are in fact looking for are innovative signs of life, playable proofs of concept, prototypes and basically anything up to but not including released games.

  • spring3+hibernate4 service 中多线程事务异常及解决

    初次使用spring3结合hibernate4做项目,迅速配置完成,测试,一切正常。

    然而,当我在service层中另外开启一个线程,线程中的方法需要进行数据库操作,这个时候,悲催的抛出了异常:-org.hibernate.HibernateException: No Session found for current thread

    当然,hibernate4的session是和当前线程绑定的,多线程中用sessionFactory.getCurrentSession()获取当前session自然不存在,不存在又不会自动创建,所以抛出了异常,无可厚非。

    于是就想着怎么解决这个问题。

    遍翻google、baidu,大部分都说如何如何配置,设置事务的传播属性propagation="REQUIRED",开启opensessioninview filter等等,无一对此问题有何解释(当然或许是我没翻到,有知道的麻烦告知)

    在http://sishuok.com/forum/blogPost/list/2625.html#7523上看到相关配置,我就想作者这个项目该多线程运行正常吧,果断下载源码,修改测试,oh。。。跟我的错一模一样!

    Virtualens: How We Made Our Project for Intel Perceptual Computing Challenge

    September 23 at 23:59 GMT was the deadline for submission of Intel Perceptual Computing Challenge projects. We squeaked in at the last minute, and we can’t wait to know the results. Instead of going crazy waiting, I decided to write about our project and how we prepared for this contest. 

    Fair warning: this isn’t necessarily a success story. Nobody can predict if our project will succeed or not. Many things could happen that we aren’t able to anticipate. Whether we win or lose, we hope that our story will be of some use to other developers.
