Product Description
The content and services available on the web continue to be accessed mostly through direct human control. But this is changing. Increasingly, users rely on automated agents that save them time and effort by programmatically retrieving content, performing complex interactions, and aggregating data from diverse sources. Programming Spiders, Bots, and Aggregators in Java teaches you how to build and deploy a wide variety of these agents-from single-purpose bots to exploratory spiders to aggregators that present a unified view of information from multiple user accounts.
You will quickly build on your basic knowledge of Java to quickly master the techniques that are essential to this specialized world of programming, including parsing HTML, interpreting data, working with cookies, reading and writing XML, and managing high-volume workloads. You’ll also learn about the ethical issues associated with bot use–and the limitations imposed by some websites.
This book offers two levels of instruction, both of which are focused on the library of routines provided on the companion CD. If your main concern is adding ready-made functionality to an application, you’ll achieve your goals quickly thanks to step-by-step instructions and sample programs that illustrate effective implementations. If you’re interested in the technologies underlying these routines, you’ll find in-depth explanations of how they work and the techniques required for customization. Read more

巴菲特致股东的信：股份公司教程
Filed Under Investing, Ebook | Leave a Comment
译者序：
巴菲特当然没有写过什么书，但他每年都要在伯克希尔·哈撒韦的公司年报中给股东写一封信，总结在过去一年中的成败得失。从挑选经理、选择投资目标、评估公司，到有效地使用金融信息，这些信涵盖面甚广。但是，在美国法律教授劳伦斯人坎宁安将这些信援特定的主题加以组织整理著成本书以前，、这些信中蕴含的思想并没有引起本应获得的广泛关注。巴菲特本人认为，这本书比到目前为止的任何一本关于他的传记都要好，如果他要挑一本书去读，那必定是这本。
巴菲特是第一位靠证券投资成为拥有几百亿美元资产的世界富豪。在过去的35年中，他执掌的伯克希尔公司每股账面价值从19美元上升至37 987美元，年复合增长率高达24．00％（见下表）。尤为难能可贵的是，伯克希尔已经是一家资产总额高达1300多亿美元的巨型企业。没有哪个人的成功是偶然的。读者看完本书之后，想必会对巴菲特的投资理念有深入全面的了解，也就不难想像他为什么会取得如此惊人的业绩。
巴菲特的许多观点与传统的管理与投资教条相抵触。例如，巴菲特认为用股票期权酬报经理会对股东产生毒害作用，他更倾向于直接用现金奖励经理。因为这些经理若是真的看好自己公司的股票，只要到二级市场上去买就可以了。许多公司的业绩增长，是因为留存了本应派发给股东的红利。如果这些用于再投资的留存收益可以产生高于市场平均收益的回报，那么留存收益显然是明智的；但若是回报率比市场的平均收益率低，那么股东就会蒙受损失。许多公司经理明知回报率低，但还喜欢留存收益，因为公司的业绩毕竟还增长了，这样他们手中的股票期权价值就会提高，这等于是拿股东的钱为自己谋利。

★价值投资者应该注重哪些信息？
★巴菲特本人怎样看公司报表，哪些业绩指标他认为最关键？
★为什么他能够面对市场的疯狂而不为所动，他是如何控制风险的？
★上市公司的价值和公司的经理之间有什么联系，经理最重要的品质是什么？

这本研究巴菲特选股之道的新著抛开了复杂的理论分析，将股王的经验转化为可以直接运用的技艺，具有很强的实用性。
“真正能体现你工作价值的核心，不在于你去非碰那些你还不理解的东西，也不在于你知道了人家上星期买了什么，而在于你有能力抓住一只行将启动的股票。”
—沃伦·巴菲特

这本《巴菲特怎样选择成长股》讲述投资者应该如何沿着巴菲特的足迹，去发现那些价值被低估的股票，去躲开一个已经十分危险的市场。作为价值投资理论的实践者和研究者，蒂默西·韦克的著作将为你提供如下知识：
★无需冒更大风险就能获得超出平均收益的三项策略
★评估作为内在价值基本要素的公司未来收益的技术
★为什么账面价值的增长是巴菲特所钟爱的衡量公司投资潜力的尺度

Everyone loves Google, and it’s the first place many people turn to locate information on the Internet. There’s a big gap, though, between knowing that you can use Google to get advance information on your blind date and having a handle on the considerable roster of fact-finding tools that the site makes available. Google Hacks reveals–and documents in considerable detail–a large collection of Google capabilities that many readers won’t have even been aware of. Want to find the best price on a pair of leg warmers? Try the Froogle price-searcher that’s hidden within the Google site. Interested in finding weblog commentary about a particular subject? Tara Calishain and Rael Dornfest call your attention to the special Google syntaxes for that purpose. This book makes it clear that there’s lots more to the Google site than typing in a few keywords and trusting the search engine to yield useful results. If you’re a programmer–or even just familiar with a HTML or a scripting language–Google opens up even further. A large part of Google Hacks concerns itself with the Google API (the collection of capabilities that Google exposes for use by software) and other programmers’ resources. For example, the authors include a simple Perl application that queries the Google engine with terms specified by the user. They also document XooMLe, which delivers Google results in XML form. In brief, this is the best compendium of Google’s lesser-known capabilities available anywhere, including the Google site itself. –David Wall
Topics covered: How to get the most from the Google search engine by using its Web-accessible features (including product searches, image searches, news searches, and newsgroup searches) and the large collection of desktop-resident toolbars available, as well as its advanced search syntax. Other sections have to do with programming with the Google API and simple “scrapes” of results pages, while further coverage addresses how to get your Web page to feature prominently in Google keyword searches.

By reviewing both the concepts of performance measurement and examples of how they are used, readers will gain the insight necessary to understand and evaluate the management of investment funds. Investment Performance Measurement makes extensive use of fully worked examples that supplement formulas and is a perfect companion to professional courses and seminars for analysts.Bruce J.
