#1:甘道夫
This programmer type looks like a short-list candidate to play Gandalf in The Lord of the Rings. He (or even she!) has a beard halfway to his knees, a goofy looking hat, and may wear a cape or a cloak in the winter. Luckily for the team, this person is just as adept at working magic as Gandalf. Unluckily for the team, they will need to endure hours of stories from Gandalf about how he or she to walk uphill both ways in the snow to drop off the punch cards at the computer room. The Gandalf type is your heaviest hitter, but you try to leave them in the rear and call them up only in times of desperation.
这种程序员看起来，就像是在《指环王》里扮演甘道夫的最佳候选人。他（甚至是她）有着快要到膝盖的胡子，一顶看起来傻傻的帽子，在冬天可能还会穿一件披风或者是斗篷。对于团队来说幸运的是，此人对自己工作的熟练程度就像甘道夫一样。但不幸的是，他们要经常忍受甘道夫长达数个小时的故事的折磨，而内容主要是关于他或者是她是如何不得不在雪地中上山下山，以把打好孔的纸带送到计算机房。甘道夫类型的程序员是你的究极武器，但是你会总是希望能把他们排到后面，只在快要绝望的时候才向他们寻求帮助。

#2: The Martyr
#2:烈士
In any other profession, The Martyr is simply a “workaholic.” But in the development field, The Martyr goes beyond that and into another dimension. Workaholics at least go home to shower and sleep. The Martyr takes pride in sleeping at the desk amidst empty pizza boxes. The problem is, no one ever asked The Martyr to work like this. And he or she tries to guilt-trip the rest of the team with phrases like, “Yeah, go home and enjoy dinner. I’ll finish up the next three week’s worth of code tonight.”
对于任何其它职业来说，烈士其实就是一个工作狂而已。但是在开发者的领域，烈士完全进入了另外一个范畴。工作狂至少会回家洗澡睡觉，而烈士们却会以睡在桌子底下的空皮萨盒子堆之中为荣。而问题是，根本就没人要求烈士们像这样工作。而且他或者她总是想用这样的措辞来使团队中的其他人感到内疚，“好的，你们回家吃完饭吧。我会在今晚会完成相当于3个星期的工作量的。”

#3: Fanboy
#3:玩家
Watch out for Fanboy. If he or she corners you, you’re in for a three-hour lecture about the superiority of Dragonball Z compared to Gundam Wing, or why the Playstation 3 is better than the XB 360. Fanboy’s workspace is filled with posters, action figures, and other knick-knacks related to some obsession, most likely imported from Japan. Not only are Fanboys obnoxious to deal with, they often put so much time into the obsession (both in and out of the office) that they have no clue when it comes to doing what they were hired to do.
小心玩家。如果他或者是她注意到了你，你很有可能就要接受3至4个小时关于龙珠z与高达谁更强、或者是playstation 3 与xbox 360哪个更好的演讲。玩家的桌子上总是堆满了明信片、动作人偶、以及其他各种各样相关的装饰品，大部分可能都是从日本进口的。玩家们不光是很难相处，他们有的时候实在是太多时间在这些东西上（无论是在办公室内外），以至于他们根本就不明白他们什么时候该干老板雇他们做的工作。

#4: Vince Neil
#4:文斯 内尔(一个比较有名的摇滚歌手)
This 40-something is a throwback to 1984 in all of the wrong ways. Sporting big hair, ripped stonewashed jeans, and a bandana here or there, Vince sits in the office humming Bon Jovi and Def Leppard tunes throughout the workday. This would not be so bad if “Pour Some Sugar on Me” was not so darned infectious.
这个40岁的家伙就像是颠三倒四的回到了1984.运动型爆炸头，发皱泛白的牛仔裤，还有一条大围巾。文斯还会在工作时间坐在办公室哼着Bon Jovi 和 Def Leppard的歌，这本来也不是很糟，如果《Pour Some Sugar on Me》不是如此的有感染力的话。
Vince is generally a fun person to work with, and actually has a ton of experience, but just never grew up. But Vince becomes a hassle when he or she tries living the rock ‘n roll lifestyle to go with the hair and hi-tops. It’s fairly hard to work with someone who carries a hangover to work every day.
总体来说，和文斯一起工作是很有趣的，实际上他有丰富的经验，只是永远长不大而已。但是如果文斯决定用他或者是她的摇滚风格来处理自己的头发和生活的时候，情况就会变得很棘手。因为和一个每天都带着宿醉未醒的人一起工作，相当困难。

#5: The Ninja
#5:忍者
The Ninja is your team’s MVP, and no one knows it. Like the legendary assassins, you do not know that The Ninja is even in the building or working, but you discover the evidence in the morning. You fire up the source control system and see that at 4 AM, The Ninja checked in code that addresses the problem you planned to spend all week working on, and you did not even know that The Ninja was aware of the project! See, while you were in Yet Another Meeting, The Ninja was working.
忍者是你们团队当中的重要人物，但是却没人能意识到这点。就好象传奇刺客一样，你不知道忍者是什么时候工作的，但是你总是在第二天早晨发现他们的成果。于是你急忙打开源代码控制系统，然后发现在临晨4点，忍者提交了一份代码，解决了一个你已经研究了一个星期的问题，而你之前甚至都不知道忍者大人知道你所作的项目的存在。明白了吧，当你还在一次次的开会的时候，忍者一直在工作。
Ninjas are so stealthy, you might not even know their name, but you know that every project they’re on seems to go much more smoothly. Tread carefully, though. The Ninja is a lone warrior; don’t try to force him or her to work with rank and file.
忍者是如此的隐蔽，你甚至都不知道他们的名字，但是你知道每一个他们参与的项目都进行的更顺利。不过，注意点，忍者是孤胆战士，不要试图强迫他们在一个严格的等级和文档制度下工作。

#6: The Theoretician
#6:理论家
The Theoretician knows everything there is to know about programming. He or she can spend four hours lecturing about the history of an obscure programming language or providing a proof of how the code you wrote is less than perfectly optimal and may take an extra three nanoseconds to run. The problem is, The Theoretician does not know a thing about software development. When The Theoretician writes code, it is so “elegant” that mere mortals cannot make sense of it. His or her favorite technique is recursion, and every block of code is tweaked to the max, at the expense of timelines and readability.
理论家知道一切编程需要知道的东西。他或者是她可以花4个小时去探讨一个很冷僻的语言，或者去证明你写的代码是如何的不完美并且有可能会在运行的时候多花3纳秒。问题在于，理论家根本就不知道什么叫软件开发。当理论家写代码的时候，他的代码是如此的“优美”，以至于我们这些凡人根本就看不懂。他或者她最喜爱的技术就是递归，每一个代码块都被使用到了极致，而代价就是工程进度和可读性。
The Theoretician is also easily distracted. A simple task that should take an hour takes Theoreticians three months, since they decide that the existing tools are not sufficient and they must build new tools to build new libraries to build a whole new system that meets their high standards. The Theoretician can be turned into one of your best players, if you can get him or her to play within the boundaries of the project itself and stop spending time working on The Ultimate Sorting Algorithm.
理论家还很容易分心。一个花一个小时就能完成的工作，理论家们往往需要三个月。因为他们认为当前的开发工具不够好，所以他们必须开发一些新的工具来构建新的库从而构建一个全新的系统来迎合他们的高标准。理论家可以成为你最好的团队成员，前提是你能让他专注于你们所做的工程本身，而不是把时间都花在究极排序算法上。

#7: The Code Cowboy
#7:代码牛仔
The Code Cowboy is a force of nature that cannot be stopped. He or she is almost always a great programmer and can do work two or three times faster than anyone else. The problem is, at least half of that speed comes by cutting corners. The Code Cowboy feels that checking code into source control takes too long, storing configuration data outside of the code itself takes too long, communicating with anyone else takes too long… you get the idea.
代码牛仔是一种无法阻止的天性。他或者她几乎总是一个厉害的编程者，并且总是能以别人2至3倍的速度完成工作。问题是，这些代码至少有一半都靠偷工减料得来的。代码牛仔认为把代码提交到源码控制系统太麻烦，把配置信息存贮在代码之外太麻烦，和其它人交流太麻烦……你懂我的意思吧。
The Code Cowboy’s code is a spaghetti code mess, because he or she was working so quickly that the needed refactoring never happened. Chances are, seven pages’ worth of core functionality looks like the “don’t do this” example of a programming textbook, but it magically works. The Code Cowboy definitely does not play well with others. And if you put two Code Cowboys on the same project, it is guaranteed to fail, as they trample on each other’s changes and shoot each other in the foot.
代码牛仔的代码就好像意大利面条一样搅在一起，因为他或者她工作的事如此之快，以至于必要的重够都没有做到。很有可能的是，七页长的核心功能代码也许看起来就像是教科书上关于“不要这么做”的示例，而这些代码居然还神奇的可以运行。代码牛仔绝对没办法和别人一起工作。而且，如果你让两个代码牛仔进入同一个工程，那这个工程一定会失败，因为一个总是被另一个人对代码做的修改而干扰，他们总是拼命的在开枪射击自己搭档的脚。
Put a Code Cowboy on a project where hitting the deadline is more important than doing it right, and the code will be done just before deadline every time. The Code Cowboy is really just a loud, boisterous version of The Ninja. While The Ninja executes with surgical precision, The Code Cowboy is a raging bull and will gore anything that gets in the way.
当按时完成一个工程比把这个工程做好更重要的时候，把一个代码牛仔加入进去吧，这个工程会在截至日期之前完成的。代码牛仔其实就是一个吵闹版的忍者。只是忍者像做外科手术一样精准的编码，而代码牛仔像一只难以控制的公牛，会把所以挡在它面的东西顶翻。

#8: The Paratrooper
#8:伞兵
You know those movies where a sole commando is air-dropped deep behind enemy lines and comes out with the secret battle plans? That person in a software development shop is The Paratrooper. The Paratrooper is the last resort programmer you send in to save a dying project. Paratroopers lack the patience to work on a long-term assignment, but their best asset is an uncanny ability to learn an unfamiliar codebase and work within it. Other programmers might take weeks or months to learn enough about a project to effectively work on it; The Paratrooper takes hours or days. Paratroopers might not learn enough to work on the core of the code, but the lack of ramp-up time means that they can succeed where an entire team might fail.
你知道那些电影吧，就是指挥官带着机密作战计划被空降到敌人战线之后。在软件开发中，这样的人叫伞兵。伞兵是你对一个将要失败的工程的最后援助。伞兵们缺乏在一个长期任务上工作的耐心。他们最大的价值是拥有快速学习一堆完全陌生的代码并且使用它们工作的惊人能力。其他程序员也许要花几个星期或者其几个月来熟悉一个工程，以便可以有效的参与其中；伞兵们只需要几个小时或者几天。伞兵快速学会的东西也许不能让他们编写核心代码，但是，没有足够的时间形成一个固定的见解可能会帮助他在整个团队失败的地方取得成功。

#9: Mediocre Man
#9:庸才
“Good enough” is the best you will ever get from Mediocre Man. Don’t let the name fool you; there are female varieties of Mediocre Man too. And he or she always takes longer to produce worse code than anyone else on the team. “Slow and steady barely finishes the race” could describe Mediocre Man’s projects. But Mediocre Man is always just “good enough” to remain employed.
“足够好了”，这就是你从一个庸才那能听到的最好的话。他或者是她总是花更多的时间写出比团队中其他任何人都更差的代码。“缓慢，刚刚符合要求”就是对庸才所作的项目的描述。但庸才们总是能做的“足够好”，以至于刚好不会被解雇。
When you interview this type, they can tell you a lot about the projects they’ve been involved with but not much about their actual involvement. Filtering out the Mediocre Man type is fairly easy: Ask for actual details of the work they’ve done, and they suddenly get a case of amnesia. Let them into your organization, though, and it might take years to get rid of them.
当你面试这种人的时候，他可以告诉你很多他到参与过的项目，但却很少提到他们到底在这些项目里做了什么。筛出这些庸才的方法很简单：问一下他所做工作的细节，他们会突然得了健忘症。但是，一旦让这种人进入你的组织，你可能要花好几年才能再摆脱他们。

#10: The Evangelist
#10:传教士
No matter what kind of environment you have, The Evangelist insists that it can be improved by throwing away all of your tools and processes and replacing them with something else. The Evangelist is actually the opposite of The Theoretician. The Evangelist is outspoken, knows an awful lot about software development, but performs very little actual programming.
无论你在用哪种编程环境，传教士总会坚持认为如果你把现有的工具和工序抛弃掉并换成其它的一些东西，会对你有很大的帮助。传教士实际上就是理论家的反面。传教士总是直来直去，对软件开发很了解，但却很少真正的去编码。
The Evangelist is secretly a project manager or department manager at heart but lacks the knowledge or experience to make the jump. So until The Evangelist is able to get into a purely managerial role, everyone else needs to put up with his or her attempts to revolutionize the workplace.
传教士有一颗项目经理或者部门经理的心，但却缺乏足够的知识或者经验来完成这个跳跃。所以在传教士最终成为一个纯管理者角色之前，其他人不得不一直忍受传教士们对于彻底革新工作环境的尝试。

不知道现在自己算是哪种类型的，貌似还是很像第7种的，都是托了客户需求一天到晚不停地变的福了，不过也有点向着第五类靠拢了。。。。。。诶，慢慢向着第一类的方向努力吧。。
