Description: 1．在内存中开辟一个虚拟磁盘空间作为文件存储器，在其上实现一个简单的单用户文件系统。在退出这个简单的文件系统时，应将该虚拟文件系统保存到磁盘上，以便下次可以再将它恢复到内存的虚拟磁盘空间中。 2．文件存储空间的分配可采用显式链接分配或其他的办法。 3．空闲空间的管理可选择位示图或其他的办法。如果采用位示图来管理文件存储空间，并采用显示链接分配方式，那么可以将位示图合并到FAT表中。 4．文件目录结构采用多级目录结构。为了简单起见，可以不使用索引结点，其中的每个目录项应包含文件名、物理地址、长度等.-1.making a virtual diskete memory as file storyge,in this district it can implement a simple single user file system .when quit this simple file system ,it shoud save the virtual file system to diskete,then it can be resumed to virtual diskete district in the memory.3.we can choose location hint map to manage the idle space or orther means.if we choose locationhint map to manage file saving space,and adopt show linking distribution mode,we can combine location hint map into FAT table.4.file directory confiuration adopts multilevel directory confiuration.to simplify,it doesn t use index dot,evrery term shoud include file name,physical dress and lenght.

\Tinix: 书中所附代码
其中很多目录中除了包含源代码(*.asm, *.inc, *.c, *.h)外，还有这样一些文件:
boot.bin 引导扇区(Boot Sector)，可通过 FloppyWriter 写入软盘(或软盘映像)。
loader.bin LOADER，直接拷贝至软盘(或软盘映像)根目录。
kernel.bin 内核(Kernel)，直接拷贝至软盘(或软盘映像)根目录。
bochsrc.bxrc Bochs 配置文件，如果系统中安装了 Bochs-2.1.1 可直接双击之运行。其它细节请见书第 2.7 节。
godbg.bat 调试时可使用此批处理文件。它假设 Bochs-2.1.1 安装在 D:\Program Files\Bochs-2.1.1\ 中。
TINIX.IMG 软盘映像。可直接通过 Bochs 或者 Virtual PC 运行。
*.com 可以在 DOS (必须为纯 DOS) 下运行的文件。
\Tools: 一些小工具 (在 VC6 下编译通过)
DescParser 描述符分析器，输入描述符的值，可以得出起基址、界限、属性等信息。
ELFParser ELF 文件分析器，可以列出一个 ELF 文件的 ELF Header、 Program Header、Section Header 等信息。
FloppyWriter 用以写引导扇区，支持软盘和软盘映像。
KrnlChecker 用以检查一个 Tinix 内核加载后位置是否正确。

Description: The main purpose of this paper is to demonstrate how to create a PDF writer by using Virtual Printer Method, which gives your applications an ability to generate PDF file through simply "printing". I am pretty sure there are many PDF writers using the same technique, saying PrimoPDF (http://www.primopdf.com/ ). However you probably wish to create your own PDF writer in some day. I here give an example to uncover the whole process of creating such kind of PDF writer.

Although the name "Java" is generally used to refer to the Java programming language, there is more to Java than the language. The Java virtual machine, Java API, and Java class file work together with the language to make Java programs run. -At the heart of Java technology lies the Java virtual machine- the abstract computer on which all Java programs run.

Description: Free open-source disk encryption software for Windows Vista/XP, Mac OS X, and Linux
Main Features:
* Creates a virtual encrypted disk within a file and mounts it as a real disk.
* Encrypts an entire partition or storage device such as USB flash drive or hard drive.
* Encrypts a partition or drive where Windows is installed (pre-boot authentication).
* Encryption is automatic, real-time (on-the-fly) and transparent.
* Provides two levels of plausible deniability, in case an adversary forces you to reveal the password:
1) Hidden volume (steganography) and hidden operating system.
2) No TrueCrypt volume can be identified (volumes cannot be distinguished from random data).
* Encryption algorithms: AES-256, Serpent, and Twofish. Mode of operation: XTS.
Further information regarding features of the software may be found in the:http://www.truecrypt.org/-Free open-source disk encryption software for Windows Vista/XP, Mac OS X, and LinuxMain Features:* Creates a virtual encrypted disk within a file and mounts it as a real disk.* Encrypts an entire partition or storage device such as USB flash drive or hard drive.* Encrypts a partition or drive where Windows is installed (pre-boot authentication).* Encryption is automatic, real-time (on-the-fly) and transparent.* Provides two levels of plausible deniability, in case an adversary forces you to reveal the password: 1) Hidden volume (steganography) and hidden operating system. 2) No TrueCrypt volume can be identified (volumes cannot be distinguished from random data).* Encryption algorithms: AES-256, Serpent, and Twofish.

Description: wave fromat
The Virtual Wave Driver package contain a Windows multimedia driver and a ActiveX DLL. It allowing you to capture/send audio (wave) streams from/to any application. It creates a Wave In/Out devices in your system.
You can use VWD to "thief" an output sound stream from the application that doesn t allow to write it into WAV file directly. Any application can send audio stream to our virtual Wave/Out device, and audio stream can be captured in our ActiveX. So you can further process the captured audio stream. While streaming, VWD can also transfer the stream to the real sound card. All transfers are made digitally, providing NO sound quality loss
