在Intel®平台上优化多媒体应用程序功耗
经过多年的硬件平台优化，硬件平台功耗逐年降低。CPU有了新的低功耗状态，显示功耗也大幅下降。然而，运行在平台上的软件所产生的功耗问题却越来越明显。在软件方面，多媒体应用程序对功耗的影响更加引人关注。事实上，研究表明优化过的多媒体应用程序播放时间是未优化过的媒体程序的两倍多。这篇白皮书介绍了设计和开发绿色多媒体应用程序需要考虑的要素，以及如何分析和优化多媒体应用软件软件在Intel®平台下的功耗。这篇白皮书旨在面向 ISVs, OEMs, 和其他技术相关人士。
跟燕青一起学Windows8应用开发：使用WinJS在已有Namespace中添加新成员
在跟燕青一起学Windows8应用开发：使用WinJS自定义Javascript的名字空间一文中，笔者已经讨论了如何用Namespace解决两个技术问题：
l 局部类定义全局化的问题。
l 多项目中代码名字冲突问题。
在博客后，笔者也留有一道思考题：在多次使用WinJS.Namespace.define定义相同名字的Namespace会出现什么情况？本篇博客就是讨论它的实际结果。
打开Study Metro App项目，建立MS1.js文件，并实现它的内容，如图1所示。
图1
图1的内容概要：定义一个局部变量desc，并且将它放入名字空间MySpace内。此外，Namespace的对象放入window.MS1中。
Let's Render Some Foliage
This blog series discusses some ideas and issues around rendering foliage. We provide a sample program (with source code) to demonstrate the ideas.
HTML5标准与性能之三：ParallelArray
前面两篇文章分别介绍了WebWorkers和Typed Array，下面我们来介绍一下另一个针对性能的JS API：ParallelArray。
Introduzione a Intel Perceptual SDK
Intel Perceptual SDK è una piattaforma software/hardware per il gesture/voice/sppech recognition. Per il software si ha a disposizione un insieme di librerie contenenti l’implementazione di algoritmi di rilevamento e riconoscimento esposti attraverso uno strato di astrazione (interfacce standard).
Per l’hardware, Perceptual SDK supporta l’utilizzo della Creative Camera.
L’utilizzo di Intel Perceptual SDK permette allo sviluppatore di semplificare lo sviluppo di applicazioni di nuova generazione basate sul paradigma NUI (Natural User Interface).
Re-imagining Apps for Ultrabook™ (Part 5): Device Motion
The fifth part of our Re-imagining Apps for Ultrabook™ video series is now available. In it, I’ll provide an overview of device motion and walk through a few ways we can take advantage of this set of capabilities in the desktop apps we create.
Enabling Connectionless DAPL UD in the Intel® MPI Library
What is DAPL UD?
Traditional InfiniBand* support involves MPI message transfer over the Reliable Connection (RC) protocol. While RC is long-standing and rich in functionality, it does have certain drawbacks: since it requires that each pair of processes setup a one-to-one connection at the start of the execution, memory consumption could (at the worst case) grow linearly as more MPI ranks are added and the number of pair connections grows.
