It’s been almost eight years since I first updated Advanced Programming in the UNIX Environment, and already so much has changed. • Before the second edition was published, The Open Group created a 2004 edition of the Single UNIX Specification, folding in the changes from two sets of corrigenda. In 2008, The Open Group created a new version of the Single UNIX Specification, updating the base definitions, adding new interfaces, and removing obsolete ones. This was called the 2008 version of POSIX.1, which included version 7 of the Base Specification and was published in 2009. In 2010, this was bundled with an updated curses interface and reissued as version 4 of the Single UNIX Specification. • Versions 10.5, 10.6, and 10.8 of the Mac OS X operating system, running on Intel processors, have been certified to be UNIX® systems by The Open Group. • Apple Computer discontinued development of Mac OS X for the PowerPC platform. From Release 10.6 (Snow Leopard) onward, new operating system versions are released for the x86 platform only. • The Solaris operating system was released in open source form to try to compete with the popularity of the open source model followed by FreeBSD, Linux, and Mac OS X. After Oracle Corporation bought Sun Microsystems in 2010, it discontinued the development of OpenSolaris. Instead, the Solaris community formed the Illumos project to continue open source development based on OpenSolaris. For more information, see http://www.illumos.org.

UNIX环境高级编程第三版(英文原版)（超清晰pdf） The first edition of the book was published by Addison-Wesley in 1992. It covered programming for the two popular families of the Unix operating system, the Berkeley Software Distribution (in particular 4.3 BSD and 386BSD) and AT&T's UNIX System V (particularly SVR4). The book covers system calls for operations on single file descriptors, special calls like ioctl that operate on file descriptors, and operations on files and directories. It covers the stdio section of the C standard library, and other parts of the library as needed. The several chapters concern the APIs that control processes, process groups, daemons, inter-process communication, and signals. One chapter is devoted to the Unix terminal control and another to the pseudo terminal concept and to libraries like termcap and curses that build atop it. Stevens adds three chapters giving more concrete examples of Unix programming: he implements a database library, communicates with a PostScript printer, and with a modem. The book does not cover network programming: this is the subject of Stevens' 1990 book UNIX Network Programming and his subsequent three-volume TCP/IP Illustrated. Stevens died in 1999 leaving a second edition incomplete. With the increasing popularity and technical diversification of Unix derivatives, and largely compatible systems like the Linux environment, the code and coverage of Stevens' original became increasingly outdated. Working with Stevens' unfinished notes, Stephen A. Rago completed a second edition which Addison-Wesley published in 2005. This added support for FreeBSD, Linux, Sun's Solaris, and Apple's Darwin, and added coverage of multithreaded programming with POSIX Threads. The second edition features a foreword by Dennis Ritchie and a Unix-themed Dilbert strip by Scott Adams. The book has been widely lauded as well written, well crafted, and comprehensive. It received a "hearty recommendation" in a Linux Journal review[1] OSNews describes it

芬兰人开发的一个专门用于DTN网络仿真的软件，用Java语言写的，该模拟器本身能支持First Contact, Epidemic, Spray and Wait, Direct delivery, PRoPHET and MaxProp这几种路由。 具体的安装方法里面有一个README.txt,很有用，不仅介绍了the ONE的一些性能，还有具体的安装以及示例。由于本身只是一些源代码，所以需要用户重新编译。具体的方法是： 1、安装Java5，配置好路径等； 2、点击文件夹下的compile.bat进行编译； 3、运行one.bat,就可以看见GUI了，此时模拟的是default。txt配置的DTN网络，如果要自己配置的DTN网络，则输入one My*.txt即可。 希望能对大家有用，另外还有一个用于DTN网络模拟的软件叫DTNsim2，是加拿大的waterloo 大学开发的
