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!

Advanced Computer Concepts For The (Not So) Common Chef: Terminology Pt 1

Before we start, I will use the next two blogs to clear up some terminology. If you are familiar with these concepts, I give you permission to jump to the next section.  I suggest any software readers still check out the other blog about threads. There is a lot of confusion, even among us software professionals.

Intel IoT Roadshow hits the Road in Seattle

The Intel IOT roadshow kicked off the year 2015 with a large showing in Seattle on February 11 and 12th.

The Intel® IoT Roadshow centers around the Intel Iot Development Kit. The goal was to educate Seattle IoT developers on how to use the kit for hardware projects - providing them with the tools they need and first hand mentorship from Intel experts. The Roadshow was preceded with a Meetup which provided the hardware community an introduction the board. This helped attendees get a head start for the hackathon - resulting in well thought out prototypes for the kit.

Advanced Computer Concepts For The (Not So) Common Chef: Introduction

While talking to a very intelligent but non-engineer colleague, I found myself needing to explain the threading and other components of the Intel® Xeon Phi™ ⅹ100 and ⅹ200 architectures. The first topic that came up was hyper-threading, and more specifically, the coprocessor’s version of hyper-threading. Wracking my brain, I finally hit upon an analogy that seemed to suit: the common kitchen.

DrDebug : Deterministic Replay based Debugging with Pin

Summary

Deterministic replay debugging is a powerful tool that can help find the cause of difficult hard-to-reproduce multi-threaded bugs. Consider using replay debugging if your application fails sporadically or if the details of the failure change from run to run. Replay debugging makes your failure totally reproducible, allowing you to use multiple debugger sessions to zero in on the root cause of your problem.

       In this article, a Minnow board MAX is used for a HW platform. The MinnowBoard is an Intel® Atom™ processor based board which introduces Intel® Architecture to the small and low cost embedded market for the developer and maker community. It has exceptional performance, flexibility, openness and standards.

    < Overview >

     This article is a tutorial for setting up OpenCV 3.0.0-beta on Yocto with Intel® Edison. We will build OpenCV 3.0.0-beta on Edison Breakout/Expansion Board using a Linux host machine and it takes up a lot of space on Edison, therefore, it is required to have at least 2GB micro SD Card as an extended storage for your Edison Breakout/Expansion Board.
