[Software Engineering] OPTsuanfa DL : 0: 本程序实现了操作系统中页式虚拟存储管理中缺页中断理想型淘汰算法，该算法在访问串中将来再也不出现的或是在离当前最远的位置上出现的页淘汰掉。这样，淘汰掉该页将不会造成因需要访问该页又立即把它调入的现象。该程序能按要求随机确定内存大小，随机产生页面数，进程数，每个进程的页数，给进程分配的页数等，然后运用理想型淘汰算法对每个进程进行计算缺页数，缺页率，被淘汰的序列等功能。-This procedure has the operating system virtual memory management page in the page fault ideal type out algorithm in the access string does not occur again in the future or furthest away from the current position on the page eliminate. In this way, eliminate the page will not be caused by the need to visit the page immediately transferred to the phenomenon of it. The program randomly determined according to the requirements of memory size, page number of randomly generated, the process of the number of pages for each process to the process of distribution of the number of pages, etc., and then out of the use of ideal-type algorithm for each process to calculate the number of pages missing, missing page rate, be eliminated sequence functions.

[Software Engineering] Understanding.the.Linux.Kernel.2nd.Edition DL : 0: The new edition of Understanding the Linux Kernel takes you on a guided tour through the most significant data structures, many algorithms, and programming tricks used in the kernel. The book has been updated to cover version 2.4 of the kernel, which is quite different from version 2.2: the virtual memory system is entirely new, support for multiprocessor systems is improved, and whole new classes of hardware devices have been added. You ll learn what conditions bring out Linux s best performance, and how it meets the challenge of providing good system response during process scheduling, file access, and memory management in a wide variety of environments.

[Software Engineering] Introduction-to-File-Infection-Techniques DL : 0: This paper was written within the scope of the author´ s own learning process, during her studies of computer science and on the basis of her own malware analyses. It was published in order to offer an introduction to several file infection techniques used by viruses, showing examples and explaining appropriate countermeasures. It is aimed at everyone who is interested in the topic of malware and does not require previous knowledge, though a basic understanding of the PE file format, virtual memory management and the Windows OS in general is advantageous.

[Software Engineering] Python-source-code-analysis DL : 0: 了更好地利用Python语言，无论是使用Python语言本身，还是将Python与C/C++交互使用，深刻理解Python的运行原理都是非常重要的。本书以CPython为研究对象，在C代码一级，深入细致地剖析了Python的实现。书中不仅包括了对大量Python内置对象的剖析，更将大量的篇幅用于对Python虚拟机及Python高级特性的剖析。通过此书，读者能够透彻地理解Python中的一般表达式、控制结构、异常机制、类机制、多线程机制、模块的动态加载机制、内存管理机制等核心技术的运行原理，同时，本书所揭示的动态语言的核心技术对于理解其他动态语言，如Javascript、Ruby等也有较大的参考价值。本书适合于Python程序员、动态语言爱好者、C程序员阅读。 -The better use of the Python language, whether using the Python language itself, or Python and C/C++ interactive use, deep understanding of Python works are very important. Book to retaining as the research object, in the C code level, analyzed deeply and in detail the Python implementation. The book not only includes a built-in objects for large Python analysis, more will be a lot of space for the Python virtual machine and the Python advanced features analysis. Through this book, readers will be able to thoroughly understand the general expression, control structure, abnormal mechanism in the Python, class, multi-threaded mechanism, the module of dynamic loading mechanism, memory management mechanism, the operation principle of the core technologies such as at the same time, the book reveals the dynamic language core technology for understanding other dynamic languages, such as Javascript, Ruby has great reference value. This book is suitable for Python programmers, dynamic language
