其中sound.c 用于录音和回放。其中特别需要注意的是:1。目前声卡似乎不能打开全双工，所以如果fd = open("/dev/dsp", O_RDWR) ，则无法录音和回放。只能分别设置RDONLY和WRONLY。即半双工方式。否则，就是在录音的时候可以听见，但是无法回放。分析下来似乎是IIC总线中只分配了一个通道给声卡，或者是只启用了一个通道，所以无法录音和放音同步进行。解决方法就是分别以RDONLY方式打开进行录音和WRONLY方式打开进行放音。 Sound1.c用于将录音保存在test.wav文件中，并利用cast test.wav > /dev/sound/dsp回放文件。此处需要注意的是，录音频率必须是44100才能正确回放。否则就会出现类似快放的效果。分析应该是cast方式利用了dsp的默认播放频率44100，所以如果录音的时候低于这个频率，这放的时候就会快放。 此外，设置采样率的时候必须设置成16bit，否则会提示出错。原因尚不知道，估计是与声卡有关。

With User Mode Linux you can create virtual Linux machines within a Linux computer and use them to safely test and debug applications, network services, and even kernels. You can try out new distributions, experiment with buggy software, and even test security. Now, for the first time, the creator and maintainer of User Mode Linux shows how to put it to work hands-on. Jeff Dike covers everything from getting started through running enterprise-class User Mode Linux servers. You ll find authoritative advice on bootup, compilation, administration, specialized configurations, and much more.

We propose a novel approach for head tracking, which combines particle filters with Isomap. The particle filter works on the low-dimensional embedding of training images. It indexes into the Isomap with its state variables to find the closest template for each particle. The most weighted particle approximates the location of head. We develop a synthetic video sequence to test our technique. The results we get show that the tracker tracks the head which changes position, poses and lighting conditions.

radius协议源码÷The Radius Stack will connect to a Radius Server. This stack implementation is built upon the UdpStack which is available in the radius{version}/util directory. A minimal set of VSAs (Vendor Specific Attributes are supported by this stack). The Radius Stack should be used as a base class. In order to implement a larger set of VSAs, one will need to subclass from the Radius Stack and implement the functionality within the virtual function processVsa(). The Radius Stack supports mostly accounting messages. The authentcation messages will be supported in a future release. A test program has been provided in the radius directory. This program shows how to subclass from the RadiusStack and how to use the api.

This directory contains the memtest 8051 firmware for the Anchor Chips EZ-USB chip. The purpose of this software is to test the different memory segments in the Ez-Usb chip. This example will output the string "good" on the 7 segment LED if the mem test passes, or it will output the first address where the memtest fails.
