致谢

这一节用来感谢那些帮助我们完成本书的人。

眼下最重要的是：这里将来也可能出现你的名字！不过，前提是你得帮忙。所以，欢迎给我们发送反馈，帮助我们一起改进和校对这本书。这样一来，你也许就能出名了！或者，至少，也能让自己的名字出现在某本书里。

特别感谢上面标有星号（*）的人；他们在提出改进建议时付出了远超寻常的努力。

此外，我们还要特别感谢 Professor Joe Meehean (Lynchburg)，他为每一章都写下了详细笔记；感谢 Professor Jerod Weinman (Grinnell) 及其全班同学，他们制作了极其出色的小册子；感谢 Professor Chien-Chung Shen (Delaware)，他对本书进行了极其细致而宝贵的阅读并提出了评论；感谢 Adam Drescher (WUSTL) 的认真阅读与建议；感谢 Glen Granzow (College of Idaho) 提供了极其详尽的意见与提示；感谢 Michael Walfish (NYU) 对本书的热情支持以及大量细致的改进建议；感谢 Peter Peterson (UMD) 提供的诸多有用反馈与评论；感谢 Mark Kampe (Pomona) 提出的详细批评意见（我们只恨没法把所有建议都改掉！）；还要感谢 Youjip Won (Hanyang) 将本书翻译成韩语（！），并提出了许多富有洞见的建议。所有这些人都在打磨本书内容方面给予了作者巨大的帮助。

同时，也要感谢这些年来修读 537 课程的数百名学生。尤其是 2008 年秋季学期的那一届学生，是他们推动了这份讲义最早的成文版本诞生（他们实在受够了没有教材可读——真是一群很会“施压”的学生！）；而之后，他们又给予了足够多的好评，让我们决定继续写下去（其中甚至包括一条极其搞笑的课程评教留言：“ZOMG! You should totally write a textbook!”）。

我们同样深深感谢那些勇敢选修 xv6 项目实验课的少数同学；这门课中的许多内容，如今已经并入 537 主课程中。2009 年春季学期包括：Justin Cherniak, Patrick Deline, Matt Czech, Tony Gregerson, Michael Griepentrog, Tyler Harter, Ryan Kroiss, Eric Radzikowski, Wesley Reardan, Rajiv Vaidyanathan, and Christopher Waclawik。2009 年秋季学期包括：Nick Bearson, Aaron Brown, Alex Bird, David Capel, Keith Gould, Tom Grim, Jeffrey Hugo, Brandon Johnson, John Kjell, Boyan Li, James Loethen, Will McCardell, Ryan Szaroletta, Simon Tso, and Ben Yule。2010 年春季学期包括：Patrick Blesi, Aidan Dennis-Oehling, Paras Doshi, Jake Friedman, Benjamin Frisch, Evan Hanson, Pikkili Hemanth, Michael Jeung, Alex Langenfeld, Scott Rick, Mike Treffert, Garret Staus, Brennan Wall, Hans Werner, Soo-Young Yang, and Carlos Griffin (almost)。

虽然他们并不直接参与本书写作，但我们的研究生让我们学到了大量关于系统的知识。在他们还在 Wisconsin 期间，我们经常与他们交流；不过，真正做事的是他们自己——而通过听他们讲述自己正在研究什么，我们几乎每周都能学到新东西。下面这份名单列出了目前和曾经与我们合作发表过论文的研究生与博士后；其中带星号（*）的人是在我们的指导下获得博士学位的：Abhishek Rajimwale, Aishwarya Ganesan, Andrew Krioukov, Ao Ma, Brian Forney, Chris Dragga, Deepak Ramamurthi, Dennis Zhou, Edward Oakes, Florentina Popovici*, Hariharan Gopalakrishnan, Haryadi S. Gunawi*, James Nugent, Joe Meehean*, John Bent*, Jun He, Kevin Houck, Lanyue Lu*, Lakshmi Bairavasundaram*, Laxman Visampalli, Leo Arulraj*, Leon Yang, Meenali Rungta, Muthian Sivathanu*, Nathan Burnett*, Nitin Agrawal*, Ram Alagappan, Samer Al-Kiswany, Scott Hendrickson, Sriram Subramanian*, Stephen Todd Jones*, Stephen Sturdevant, Sudarsun Kannan, Suli Yang*, Swaminathan Sundararaman*, Swetha Krishnan, Thanh Do*, Thanumalayan S. Pillai*, Timothy Denehy*, Tyler Harter*, Venkat Venkataramani, Vijay Chidambaram*, Vijayan Prabhakaran*, Yiying Zhang*, Yupu Zhang*, Yuvraj Patel, Zev Weiss*。

我们的研究生长期以来主要通过美国国家科学基金会（NSF）、美国能源部科学办公室（DOE）以及产业资助获得经费支持。我们尤其感谢 NSF 多年来的支持，因为我们的研究工作塑造了本书中许多章节的内容。

我们还要感谢 Thomas Griebel，他强烈要求我们给这本书换一个更好的封面。虽然我们没有采用他的具体建议（一只恐龙——你敢信？），但如果没有他，如今封面上那张漂亮的哈雷彗星图片大概也不会出现。

最后，我们还要特别感谢 Aaron Brown。他很多年前第一次修这门课（2009 年春季），之后又修了 xv6 实验课（2009 年秋季），再后来又做了大约两年的研究生助教（从 2010 年秋季到 2012 年春季）。他不知疲倦的工作极大改进了这些项目的状态（尤其是 xv6 相关项目），从而改善了 Wisconsin 无数本科生和研究生的学习体验。用 Aaron 一贯简洁的表达来说就是：“Thx.”
