EV-DO

EVDO(EV-DO)实际上是三个单词的缩写:Evolution(演进)、DataOnly。其全称为:CDMA20001xEV-DO,是CDMA20001x演进(3G)的一条路径的一个阶段。这一路径有两个发展阶段,第一阶段叫1xEV-DO,即“DataOnly”,它可以使运营商利用一个与IS-95或CDMA2000相同频宽的CDMA载频就可实现高达2.4Mbps的前向数据传输速率,已被国际电联ITU接纳为国际3G标准,并已具备商用化条件。第二阶段叫1xEV-DV。1xEV-DV意为“DataandVoice”,它可以在一个CDMA载频上同时支持话音和数据。

    The project Adventure is a simple text-based adventure game. The game, as given, involves the hero trying to find his way from a deep dark forest to home and his true love. There s very little else the player can do apart from moving from place to place. It s not really very interesting. This project can be of use beyond the given, rather boring forest adventure though. You can use it as a basis for developing your own adventure game with different, more interesting commands, areas, items, people and so on. The package ope.adventure contains classes to describe the game world.

  • 这是一个Linux下的USB摄像头捕捉程序

    这是一个Linux下的USB摄像头捕捉程序,是一个调用V4L2(Video for Linux 2)非常好的例子。英文介绍为:This is a driver for the USB video bridge USBVision from Zoran/Nogatech, a USB-only cable used in many "webcam" devices. It supports streaming and capture of color or monochrome video via the Video4Linux API. Most V4L apps are compatible with it, but a few video-conferencing programs do not work yet.

    American Gladiator,You are consulting for a game show in which n contestants are pitted against n gladiators in order to see which contestants are the best. The game show aims to rank the contestants in order of strength this is done via a series of 1-on-1 matches between contestants and gladiators. If the contestant is stronger than the gladiator, then the contestant wins the match otherwise, the gladiator wins the match. If the contestant and gladiator have equal strength, then they are “perfect equals” and a tie is declared. We assume that each contestant is the perfect equal of exactly one gladiator, and each gladiator is the perfect equal of exactly one contestant. However, as the gladiators sometimes change from one show to another, we do not know the ordering of strength among the gladiators.

  • We often get questions about how the deflate() and inflate() functions should be used. Users wonder

    We often get questions about how the deflate() and inflate() functions should be used. Users wonder when they should provide more input, when they should use more output, what to do with a Z_BUF_ERROR, how to make sure the process terminates properly, and so on. So for those who have read zlib.h (a few times), and would like further edification, below is an annotated example in C of simple routines to compress and decompress from an input file to an output file using deflate() and inflate() respectively. The annotations are interspersed between lines of the code. So please read between the lines. We hope this helps explain some of the intricacies of zlib.
