北京大學ACM比賽題目
In 1742, Christian Goldbach, a German amateur mathematician, sent a letter to Leonhard Euler in which he made the following conjecture:
Every even number greater than 4 can be
written as the sum of two odd prime numbers.
For example:
8 = 3 + 5. Both 3 and 5 are odd prime numbers.
20 = 3 + 17 = 7 + 13.
42 = 5 + 37 = 11 + 31 = 13 + 29 = 19 + 23.
Today it is still unproven whether the conjecture is right. (Oh wait, I have the proof of course, but it is too long to write it on the margin of this page.)
Anyway, your task is now to verify Goldbach s conjecture for all even numbers less than a million.
WinChat was created in late 2000 by Spectre, DeMENted and Unique_T.
You can connect to WinChat.Net by pointing your IRC client at irc.winchat.net.
Or you can start a Java client right now.
A framework written in Java for implementing high-level and dynamic languages, compiling them into Java bytecodes.
An implementation of Scheme, which is in the Lisp family of programming languages. Kawa is a featureful dialect in its own right, and additionally provides very useful integration with Java. It can be used as a “scripting language”, but includes a compiler and all the benefits of a “real” programming language, including optional static typing.
linux下用C語言寫的聊天程序！/*BUG and NOTE:
Not join protect to Shared Memory Segments,example Semaphore Arrays.
Not check the parameters validity.
When transmit may be error.
If the client program no right exit,others cannot know,the service program shouldbe check the client program whether exist timing.
The program when exit(), it do not delete the Shared Memory Segments,you maybe use atexit() but the program have some processes.
When one process is exit(),others is continue.
The service program s action is few.
And so on. */

In this book, you will acquire a comprehensive
understanding of GIMP Toolkit (GTK+) that can help you to become a proficient graphical
programmer. Before continuing, you should be aware that this book is aimed at C programmers,
so we will jump right into using GTK+. Time will not be spent covering information you
already know.
Advanced UNIX Programming is the long-awaited (19 years!) update to the 1985 original. Maybe "update" isn t the right word--of the 750-or-so pages in the new book, there are maybe two dozen paragraphs that are unchanged. The original covered about 70 system calls, and the new one covers about 300. （這是Advanced UNIX Programming的附書源碼）
This a sample Plug and Play filter driver that provides WMI data blocks. Typically, driver writers will copy the sample code into their own driver and make any minor modifications so that the WMI data blocks are always available when the driver is loaded. Alternatively, WmiSamp can be left as a filter driver if WMI data blocks should only be made available when the filter driver is loaded.
