Primo Webcast Italiano su Intel Realsense

Il primo Webcast di introduzione alla tecnologia Intel Realsense si e' svolto Lunedi' 15 Settembre 2014 per mano di Massimo Bonanni e mia, in qualita' di Intel Software Innovator per Realsense italiani.

La sessione prevedeva la presentazione delle caratteristiche del nuovo SDK ed alcune demo per vedere il Sistema in Azione in anteprima.

Alla fine e' abbiamo presentato il nuovo Realsense App Challenge 2014, la grande competizione aperta a tutti I developer con un montepremi da capogiro: 1 Milione di DOLLARI!

 

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!

With STEM Education, Women Can Create Both Technology and Their Own Futures

The decline of young women's participation in science, technology, engineering and math (STEM) education in the U.S. is alarming for many reasons, but it's especially resonant for someone like me, whose cultural heritage is Indian. (Watch this short video, where I discuss these topics in person.)
