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!

Dynamic Languages take over the internet

What would happen if you were hauling a trailer down the road, and suddenly you realized that the trailer you thought you were pulling passes you on the highway. (Which I guess can actually happen, I just saw a video capture of this exact disaster, happening to a trucker). You might not feel kind of blind-sided!

This is kind of the way I feel when a technology trend sneaks up on me and suddenly I feel like I'm way behind the curve.

Innovation Think!

I have been hosting a program, started in March of 2015, called “Innovation Think” with the intent to get people exposed to technology that stimulates innovation either directly or through the exercising of the creative mind.

Intel® XDK Helping Change the World

Ngesa loves Intel architecture and encourages new developers to start coding with Intel® XDK, which enables them to design and deploy applications across multiple operating systems and also lets them scale their apps to reach more users. He describes the Intel Galileo board as “one of the best developer boards for all electronics enthusiasts” as it enables them to do cool things with wearables by improving their software and electronics skills.

OpenCV 3.0.0 ( IPP & TBB enabled ) on Yocto with Intel® Edison with new Yocto image release

This article is a tutorial for setting up OpenCV 3.0.0 on Yocto with Intel® Edison. We will build OpenCV 3.0.0 on Edison Breakout/Expansion Board using a Windows/Linux host machine. In this article, we will enable Intel® Integrated Performance Primitives ( IPP ) and Intel® Threading Building Blocks ( TBB ) to optimize and parallelize some OpenCV functions. For example, cvHaarDetectObjects(...) , an OpenCV function that detects objects of different sizes in the input image, is parallelized with the TBB library. By doing this, we can fully utilize the dual-core of Edison.
