<p>本文译自美国时代（time.com）的《<a href="http://www.time.com/time/specials/packages/printout/0,29239,2032304_2032746_2032903,00.html" target="_blank">The Men Who Stole the World</a>》，原作者：Lev Grossman。相当有传奇色彩，读起来很爽，翻译过来。译得不好，还请大家指正。本中的四个程序员可能并不是那么声名显赫，而且也很不老实，或许算不上成功，不过他们的确改变了世界。<strong>而本文有分析了互联网上P2P的那些事，相当的有参考价值</strong>。</p>

<p>————————正文————————</p>
<p>十年前，有四个年轻人改变了这个世界的运作方式。他们使用的并不是法律或是武器或是金钱，而是使用软件来改变世界。他们当时有着激进和极具破坏性的想法，并把这些想法付诸于代码，在Internet上以免费自由方式发布。这四个人，没有一个完成了大学学业，却奠定了今天我们习惯的数字媒体环境的基础。然后，因为各种原因，他们也迅速地消失在公众视野中。</p>
<p>1999年，美国东北大学的一个叫Shawn Fanning的一年级新生开发Napster，从此，成为了P2P文件共享和不需要大型机构或零售商就可以获得音乐的先锋和范例。《时代周刊》和《财富》把他放上了封面。那时，他在19岁。</p>
<p>就在同一年，一个挪威的只有十几岁的年轻人 Jon Lech Johansen，他和另两个今天都不为人知的程序员，写下了一个程序解密了商业的DVD，而他成为了全球盛名的“ DVD Jon.”，那年，他只有15岁。</p>
<p>而在1997年，Justin Frankel，一个亚利桑那州塞多纳的18岁的黑客，开发了一个免费的MP3播放器——WinAmp，其成为了Windows操作系统上装机必备的软件，并造就了主流数字音乐的革命。在他发布的第18个月内，1500万人下载了这个软件。而三年后，Frankel 开发了 Gnutella，一个P2P的文件共享协议，没有中心结点，不像 Napster，其不可能被关闭。目前有上百万人还在使用它。</p>
<p>2001年，Bram Cohen, 当年 26 岁，开发了一个P2P的文件传输共享协议—— BitTorrent，其以全新一流的架构全面优化了网络上大文件的共享和传输效率。 BitTorrent 也变成了整个Internet上发布大数据和文件的一个标准。</p>

<p><a href="http://www.ailab.si/orange"><img decoding="async" id="BLOGGER_PHOTO_ID_5543415731299792802" class="alignleft" src="/uploads/2010/12/orange-data-mining-software.jpg" border="0" alt="" srcset=""/></a><a href="http://www.ailab.si/orange">Orange</a> 是一个基于组件的数据挖掘和机器学习软件套装，它的功能即友好，又很强大，快速而又多功能的可视化编程前端，以便浏览数据分析和可视化，基绑定了Python以进行脚本开发。它包含了完整的一系列的组件以进行数据预处理，并提供了数据帐目，过渡，建模，模式评估和勘探的功能。其由C++ 和 Python开发，它的图形库是由跨平台的Qt框架开发。</p>
<h4>RapidMiner</h4>
<p><a href="http://rapidminer.com/" target="_blank"><img decoding="async" id="BLOGGER_PHOTO_ID_5543415710727537026" class="alignleft" style="border: 0px initial initial;" src="/uploads/2010/12/data-mining-software-rapidminer.jpg" border="0" alt="" srcset=""/></a><a href="http://rapidminer.com/" target="_blank">RapidMiner</a>, 以前叫 YALE (Yet Another Learning Environment), 其是一个给机器学习和数据挖掘和分析的试验环境，同时用于研究了真实世界数据挖掘。它提供的实验由大量的算子组成，而这些算子由详细的XML 文件记录，并被RapidMiner图形化的用户接口表现出来。RapidMiner为主要的机器学习过程提供了超过500算子，并且，其结合了学习方案和Weka学习环境的属性评估器。它是一个独立的工具可以用来做数据分析，同样也是一个数据挖掘引擎可以用来集成到你的产品中。</p>

<div>某猎头收集了140多个Google的面试题，都张到他的Blog中了，主要是下面这些职位的，因为被墙，且无任何敏感信息，所以，我原文搬过来了。</div>
<div>
<ul>
<li>Product Marketing Manager</li>
<li>Product Manager</li>
<li>Software Engineer</li>
<li>Software Engineer in Test</li>
<li>Quantitative Compensation Analyst</li>
<li>Engineering Manager</li>
<li>AdWords Associate</li>
</ul>
</div>
<p>这篇Blog例举了Google用来面试下面这几个职位的面试题。很多不是很容易回答，不过都比较经典与变态，是Google，Microsoft，Amazon之类的公司的风格。对于本文，我没有翻译，因为我相信，英文问题是最好的。不过对于有些问题，我做了一些注释，不一定对，但希望对你有帮助启发。对于一些问题，如果你百思不得其解，可以Google一下，StackOverflow或是Wikipedia上可能会给你非常全面的答案。</p>

<p><a href="http://groovy.codehaus.org/" target="_blank">Groovy</a>是一个基于 Java虚拟机的敏捷 动态语言。构建在强大的Java语言之上 并 添加了从Python，Ruby和Smalltalk等语言中学到的 诸多特征。为Java开发者提供了 现代最流行的编程语言特性，而且学习成本很低（几乎为零）。在以前的酷壳的<a rel="bookmark" href="/articles/2631.html">五大基于JVM的脚本语言</a>中也介绍过它。</p>
<p>下面，让我们看看他的一个createArray的实现，请大家前去围观下面的Groovy的trunk上的源码吧。真是很好很强大。</p>

<p>这里摘上前几个createArray重载函数让大家看看，（一共有250个重载函数）</p>
<pre data-enlighter-language="java" class="EnlighterJSRAW">public class ArrayUtil {

<p>在<a href="http://www.reddit.com/r/todayilearned/comments/ed39q/til_how_to_make_google_beatbox_for_you/" target="_blank">Reddit</a>上有人发布了怎么使用Google的翻译来玩beat box，很有趣，转过来。</p>

<img decoding="async" loading="lazy" title="Google 翻译 玩转 Beat box" src="/uploads/2010/12/google_beat_box.jpg" alt="" width="500" height="164" srcset=""/></p>
<p>下面是相关步骤：</p>
<p style="text-align: left; padding-left: 30px;">1) Go to <a href="https://translate.google.com/" target="_self">Google Translate</a></p>
<p style="text-align: left; padding-left: 30px;">2) 把翻译语言设置成从 German 翻译到 German。（德语）</p>
<p style="text-align: left; padding-left: 30px;">3) 拷贝粘贴这个字符串到translate中：<br/>
pv zk pv pv zk pv zk kz zk pv pv pv zk pv zk zk pzk pzk pvzkpkzvpvzk kkkkkk bsch</p>
<p style="text-align: left; padding-left: 30px;">4) 把声音开大，点击“朗读”，</p>
<p>另，如果你在Google里以 “Google beatbox” 作为关键词搜索，你会看到 Google Translate出现在最前面的搜索结果中。</p>
