Software Testing, Second Edition provides practical insight into the world of software testing and quality assurance. Learn how to find problems in any computer program, how to plan an effective test approach and how to tell when software is ready for release. Updated from the previous edition in 2000 to include a chapter that specifically deals with testing software for security bugs, the processes and techniques used throughout the book are timeless. This book is an excellent investment if you want to better understand what your Software Test team does or you want to write better software.

linux filesystem bootdisk-howto.This document describes how to design and build boot/root diskettes for Linux. These disks can be used as rescue disks or to test new system components. You should be reasonably familiar with system administration tasks before attempting to build a bootdisk. If you just want a rescue disk to have for emergencies,

This leon3 design is tailored to the Altera NiosII Startix2 Development board, with 16-bit DDR SDRAM and 2 Mbyte of SSRAM. As of this time, the DDR interface only works up to 120 MHz. At 130, DDR data can be read but not written. NOTE: the test bench cannot be simulated with DDR enabled because the Altera pads do not have the correct delay models. * How to program the flash prom with a FPGA programming file 1. Create a hex file of the programming file with Quartus. 2. Convert it to srecord and adjust the load address: objcopy --adjust-vma=0x800000 output_file.hexout -O srec fpga.srec 3. Program the flash memory using grmon: flash erase 0x800000 0xb00000 flash load fpga.srec

其中sound.c 用于錄音和回放。其中特別需要注意的是:1。目前聲卡似乎不能打開全雙工，所以如果fd = open("/dev/dsp", O_RDWR) ，則無法錄音和回放。只能分別設(shè)置RDONLY和WRONLY。即半雙工方式。否則，就是在錄音的時候可以聽見，但是無法回放。分析下來似乎是IIC總線中只分配了一個通道給聲卡，或者是只啟用了一個通道，所以無法錄音和放音同步進行。解決方法就是分別以RDONLY方式打開進行錄音和WRONLY方式打開進行放音。 Sound1.c用于將錄音保存在test.wav文件中，并利用cast test.wav > /dev/sound/dsp回放文件。此處需要注意的是，錄音頻率必須是44100才能正確回放。否則就會出現(xiàn)類似快放的效果。分析應(yīng)該是cast方式利用了dsp的默認播放頻率44100，所以如果錄音的時候低于這個頻率，這放的時候就會快放。 此外，設(shè)置采樣率的時候必須設(shè)置成16bit，否則會提示出錯。原因尚不知道，估計是與聲卡有關(guān)。

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.
