你想探究Ruby的极致吗？Ruby Cookbook就是关于这一当今最热门编程语言的最全面的问题求解指南。本书使用清晰的阐述和数千行可以在你的项目中使用的源代码，来为在实际应用中可能碰到的数百个问题提供解决方法。从数据结构到集成前沿技术的算法，Ruby Cookbook为每一位编程人员都准备了一些专题。初学者和资深的Ruby专家都可以从本书学习到下列专题中有关Ruby编程的知识和技巧：
●字符串和数字
●数据库
●数组和哈希表
●图像
●类、模块和命名空间

●反射机制和元编程
●XML和HTML处理
●多任务
●Ruby on Rails（包括Ajax 集成）
●图形界面和终端界面
如果你需要一个网络应用程序，本书将向你展示如何使用Rails来开始进行开发。假设你需要重命名数以千计的文件，本书将告诉你如何使用Ruby来完成诸如此类的日常任务。你还可以学习如何使用Ruby读写微软Excel表格文件，如何使用贝叶斯（Bayesian）过滤器进行文本归类以及如何创建PDF文件。甚至本书还将介绍一些冒傻气的把戏，比如如何让你的键盘灯闪烁不停。
总而言之，在目前已写成的关于Ruby的书中，Ruby Cookbook是最有用的一本。如果你需要解决一个Ruby问题，大可不必进行重复劳动，就直接在本书中寻找现成答案吧。
Lucas Carlson是一位专注于使用Rails进行网络开发的专业Ruby程序员。他是6个Ruby库程序的作者，也对其他很多库程序有所贡献，其中包括Rails以及RedCloth。
Leonard Richardson负责为多种编程语言开发和维护库程序，其中包括Rubyful Soup。
“程序员并不是仅仅靠语法知识就可以生存的，而是要靠他们所编写的每一行实际的代码。本书充满了实用的方法、技巧、知识和智慧。我希望它将读者的Ruby编程带入更高境界。”
－ Yukihiro（Matz）Matsumoto，Ruby的作者
“你认为书中各个主题不过是些传统的日常菜谱，错，其实它们全都是被涂上了粘稠的荷兰奶酪酱的美味。哦，伙计，这就是实例：杂凑的版本系统，几个BitTorrent的客户端以及你走失的恐龙的寻物启事。有关各种协议的这一章好有趣。好像大快朵颐后浓稠香甜的酱汁将从你的嘴边流下来！对了，还有些大块的咸肉。”

The animal on the cover of Ruby Cookbook is a side-striped jackal (Canis adustus),
found mostly in central and southern Africa. These jackals avoid the open, prefer-
ring thickly wooded areas on the edge of savannas and forests. They occasionally
make their way into cities. Side-striped jackals are rare but not considered endan-
gered. There are reserves for these jackals at the Serengeti National Park in Tanzania
and at the Akagera National Park in Rwanda.
Side-striped jackals are about 15 inches tall and weigh between 16 and 26 pounds.
This jackal has a light grey coat with a white stripe from shoulder to hip, and a
white-tipped tail. The diet of side-striped jackals consists largely of wild fruits, small
mammals, and insects. They also eat carrion and are adept scavengers; they will
follow a lion or other big cat to a kill. The jackals usually live singly or in pairs, but
they sometimes gather in family units of up to six members. Their lifespan is about
10 to 12 years.
Jackals have been an object of superstition because of their association with carrion
and death, and and because of their eerie nocturnal noises: they hoot, yap, and make a
kind of screaming yell. Perhaps because jackals were often found prowling and
hunting the edges of the desert near cemeteries, the ancient Egyptian god of
embalming and gatekeeper of the path of the dead, Anubis, was depicted as a jackal-
headed man. Anubis served as a psychopomp, conducting souls to the underworld,
where he weighed their hearts on a scale to determine whether they would be
admitted to the underworld or cast to the crocodile-headed demon, Ammit.
