2008/9/27 找到了一个长期困扰的pagetagging日志问题的解决之前我们的日志统计采取了google analytics一样的page tagging的机制,经过一个很长的痛苦经验后发现,当连接的target=“_self"的时候,统计到的会比实际到达目标页的数量少很多,进40%左右。 今天读《高性能网站建设指南 -- 前端工程师技能精髓》(High Performance Web Sites)时看到Steve Souders同学和Yahoo的同学们已经发现了这个问题,并给出了原因和解决方案。 通常的用beacon来记录的代码如下, <a href="http://en.wikipedia.org/wiki/Performance" <script> 这里的问题就是发送beacon和页面被卸载之间出现竞争,导致时序是不确定的,所以出现了40%的统计差距。 解决方案: 1, 利用图片beacon的onload事件确保在页面卸载之前beacon已经发送完毕,代码如下 <a href="http://en.wikipedia.org/wiki/Performance" <script> function gotoUrl() { 2,使用XMLHTTPRequest来发送beacon, 在readyState到2的时候再unload页面,代码如下 <a href="http://en.wikipedia.org/wiki/Performance" <!-- Dependency --> <!-- Source file --> function resultBeacon(anchor) { gXhrObj = getXHRObject(); } function xhrCallback(respAr) { function gotoUrl() { // Find the right syntax for creating an XHR object. try { 代码来自http://stevesouders.com/hpws/xhr-beacon.php
总结: 看到这么简洁的解决方案,心里又喜又卑,喜得是又一个头大的问题被解决了,卑的是为什么这么简洁的自己没有想到,我们实验了各种情况,排除了不少的可能,最后估计也是beacon图片请求的发送和页面unload的时序不确定带来的问题,但是没有进行更多的思考和实验的得到解决方案,以后要加强思考和多动手实践。 十一读书计划之High Performance Books by Yahoo!sHigh Performance Web Sites中文版读完,英文以前看过,中文的快看完了 Building Scalable Web Sites之前浏览一遍,再细看一遍 High Performance MySQL, 数据库知识和应用不细,补足一下 2008/9/20 the Meaning of Life哈佛主席Drew Gilp Faust就最常被学生问到的问题之一,“为什么大家都去了华尔街”,做了这次的本科毕业生的毕业典礼演讲。 很遗憾,我没有能够光荣的站在毕业典礼上听许智宏校长告诉我这些,但是从04年,每一年都会从各种来源看到朱苏力在法学院毕业典礼的,慈祥如父般的不舍和担忧,又充满期待和鼓励,又最后一次的谆谆教诲如何扬帆远航 这个演讲中,Faust分析了为什么会问这个问题 很多的焦虑,怀疑和恐惧,都来自这个很少有人敢直面说出的问题, 活着的意义是什么? (the Meaning of Life) 这个焦虑又有两个方面, 1,大家都希望过有意义的生活,同时又是成功的生活。这就是为什么我们中很多人有很大的原因追寻一个高薪的工作,我们觉得高的薪水体现了我们的价值,社会对我们价值的承认。同时,我们希望能多做有意义的事情。但通常要么觉得做的事情没有意义,要么觉得unapreciated并且努力寻找一个更大的舞台。 2,大家都希望过的开心,幸福 最后,她给出了建议不要害怕尝试,只有试过了才知道是否有意义,有价值,才不会因为不去尝试而悔恨。一个很有趣的parking-space理论。Don’t park 20 blocks from your destination because you think you’ll never find a space. Go where you want to be and then circle back to where you have to be. 前几天看到一个blog说,IT或者更详细的说互联网,是一个没有人敢正经谈理想的行业,employer或者boss不敢问员工他的理想是什么,因为基本不可能是把被分配的任务做出花来,然后boss一问“你什么理想啊?”,答“我想做服务千万用户的需求的网站”,然后第二天就辞职了,所以出于礼貌,boss也不问,员工也只是把分内的活做好。大家都难,boss难怎么能忽悠住这些人给自己的梦想卖命,员工难怎么能追求自己的梦想,而不是一直被忽悠。 其实何止是IT, 有多少人是在一天的辛苦后和早起的闹铃声中想,I do this all for the damn money, 不难理解为什么这么多人不eat their own dogfood, 做牛奶的不喝自己家的牛奶,养猪的不吃猪肉,办学校的孩子不敢让自己的孩子在国内上学,这是一个多么恐怖的事情啊。 http://harvardmagazine.com/web/commencement/faust-baccalaureate-address-2008 Baccalaureate Address 2008June 3, 2008President Drew Gilpin Faust’s speech at the Baccalaureate service for the Harvard College class of 2008 on June 3. In the curious custom of this venerable institution, I find myself standing before you expected to impart words of lasting wisdom. Here I am in a pulpit, dressed like a Puritan minister — an apparition that would have horrified many of my distinguished forebears and perhaps rededicated some of them to the extirpation of witches. This moment would have propelled Increase and Cotton into a true “Mather lather.” But here I am and there you are and it is the moment of and for Veritas. You have been undergraduates for four years. I have been president for not quite one. You have known three presidents; I one senior class. Where then lies the voice of experience? Maybe you should be offering the wisdom. Perhaps our roles could be reversed and I could, in Harvard Law School style, do cold calls for the next hour or so. We all do seem to have made it to this point — more or less in one piece, though I recently learned that we have not provided you with dinner since May 22. I know we need to wean you from Harvard in a figurative sense. I never knew we took it quite so literally. But let’s return to that notion of cold calls for a moment. Let’s imagine [if] this were a baccalaureate service in the form of Q & A, and you were asking the questions. “What is the meaning of life, President Faust? What were these four years at Harvard for? President Faust, you must have learned something since you graduated from college exactly 40 years ago.” (Forty years. I’ll say it out loud since every detail of my life — and certainly the year of my Bryn Mawr degree — now seems to be publicly available. But please remember I was young for my class.) In a way, you have been engaging me in this Q & A for the past year on just these questions, although you have phrased them a bit more narrowly. And I have been trying to figure out how I might answer and, perhaps more intriguingly, why you were asking. Let me explain. It actually began when I met with the UC [Undergraduate Council] just after my appointment was announced in the winter of 2007. Then the questions continued when I had lunch at Kirkland House, dinner at Leverett, when I met with students in my office hours—even with some recent graduates I encountered abroad. The first thing you asked me about wasn’t the curriculum or advising or faculty contact or even student space. In fact, it wasn’t even alcohol policy. Instead, you repeatedly asked me: Why are so many of us going to Wall Street? Why are we going in such numbers from Harvard to finance, consulting, i-banking? There are a number of ways to think about this question and how to answer it. There is the Willie Sutton approach. You may know that when he was asked why he robbed banks, he replied, “Because that’s where the money is.” Professors Claudia Goldin and Larry Katz, whom many of you have encountered in your economics concentration, offer a not dissimilar answer based on their study of student career choices since the seventies. They find it notable that, given the very high pecuniary rewards in finance, many students nonetheless still choose to do something else. Indeed, 37 of you have signed on with Teach for America; one of you will dance tango and work in dance therapy in Argentina; another will be engaged in agricultural development in Kenya; another, with an honors degree in math, will study poetry; another will train as a pilot with the U.S. Air Force; another will work to combat breast cancer. Numbers of you will go to law school, medical school, graduate school. But, consistent with the pattern Goldin and Katz have documented, a considerable number of you are selecting finance and consulting. The Crimson’s survey of last year’s class reported that 58 percent of men and 43 percent of women entering the workforce made this choice. This year, even in challenging economic times, the figure is 39 percent. [For more information on the careers research by professors Goldin and Katz, see "Flocking to Finance," May-June, page 18.] High salaries, the all but irresistible recruiting juggernaut, the reassurance that so many of your friends will be working and living and enjoying the Big Apple alongside you, the promise of interesting work — there are lots of ways to explain these choices. For some of you, it is a commitment for only a year or two in any case. Others believe they will best be able to do good by first doing well. Yet, you ask me why you are following this path. I find myself in some ways less interested in answering your question than in figuring out why you are posing it. If Professors Goldin and Katz have it right; if finance is indeed the “rational choice,” why do you keep raising this issue with me? Why does this seemingly rational choice strike a number of you as not understandable, as not entirely rational, as in some sense less a free choice than a compulsion or necessity? Why does this seem to be troubling so many of you? You are asking me, I think, about the meaning of life, though you have posed your question in code — in terms of the observable and measurable phenomenon of senior career choice rather than the abstract, unfathomable and almost embarrassing realm of metaphysics. The Meaning of Life — capital M, capital L — is a cliché: easier to deal with as the ironic title of a Monty Python movie or the subject of a Simpsons episode than as a matter about which one would dare admit to harboring serious concern. But let’s for a moment abandon our Harvard savoir-faire, our imperturbability, our pretense of invulnerability, and try to find the beginnings of some answers to your question. I think you are worried because you want your lives not just to be conventionally successful, but to be meaningful, and you are not sure how those two goals fit together. You are not sure if a generous starting salary at a prestigious brand-name organization, together with the promise of future wealth, will feed your soul. Why are you worried? Partly it is our fault. We have told you from the moment you arrived here that you will be the leaders responsible for the future, that you are the best and the brightest on whom we will all depend, that you will change the world. We have burdened you with no small expectations. And you have already done remarkable things to fulfill them: your dedication to service demonstrated in your extracurricular engagements, your concern about the future of the planet expressed in your vigorous championing of sustainability, your reinvigoration of American politics through engagement in this year’s presidential contests. But many of you are now wondering how these commitments fit with a career choice. Is it necessary to decide between remunerative work and meaningful work? If it were to be either/or, which would you choose? Is there a way to have both? You are asking me and yourselves fundamental questions about values, about trying to reconcile potentially competing goods, about recognizing that it may not be possible to have it all. You are at a moment of transition that requires making choices. And selecting one option — a job, a career, a graduate program — means not selecting others. Every decision means loss as well as gain — possibilities forgone as well as possibilities embraced. Your question to me is partly about that—about loss of roads not taken. Finance, Wall Street, “recruiting” have become the symbol of this dilemma, representing a set of issues that is much broader and deeper than just one career path. These are issues that in one way or another will at some point face you all: as you graduate from medical school and choose a specialty—family practice or dermatology; as you decide whether to use your law degree to work for a corporate firm or as a public defender; as you decide whether to stay in teaching after your two years with TFA. You are worried because you want to have both a meaningful life and a successful one; you know you were educated to make a difference not just for yourself, for your own comfort and satisfaction, but for the world around you. And now you have to figure out the way to make that possible. I think there is a second reason you are worried—related to but not entirely distinct from the first. You want to be happy. You have flocked to courses like “Positive Psychology”—Psych 1504—and “The Science of Happiness” in search of tips. But how do we find happiness? I can offer one encouraging answer: get older. Turns out that survey data show older people—that is, my age—report themselves happier than do younger ones. But perhaps you don’t want to wait. As I have listened to you talk about the choices ahead of you, I have heard you articulate your worries about the relationship of success and happiness—perhaps, more accurately, how to define success so that it yields and encompasses real happiness, not just money and prestige. The most remunerative choice, you fear, may not be the most meaningful and the most satisfying. But you wonder how you would ever survive as an artist or an actor or a public servant or a high-school teacher. How would you ever figure out a path by which to make your way in journalism? Would you ever find a job as an English professor after you finished who knows how many years of graduate school and dissertation writing? The answer is: you won’t know till you try. But if you don’t try to do what you love—whether it is painting or biology or finance—if you don’t pursue what you think will be most meaningful, you will regret it. Life is long. There is always time for Plan B. But don’t begin with it. I think of this as my parking-space theory of career choice, and I have been sharing it with students for decades. Don’t park 20 blocks from your destination because you think you’ll never find a space. Go where you want to be and then circle back to where you have to be. You may love investment banking or finance or consulting. It might be just right for you. Or you might be like the senior I met at lunch at Kirkland who had just returned from an interview on the West Coast with a prestigious consulting firm. “Why am I doing this?” she asked. “I hate flying, I hate hotels, I won’t like this job.” Find work you love. It is hard to be happy if you spend more than half your waking hours doing something you don’t. But what is ultimately most important here is that you are asking the question—not just of me, but of yourselves. You are choosing roads and at the same time challenging your own choices. You have a notion of what you want your life to be and you are not sure the road you are taking is going to get you there. This is the best news. And it is also, I hope, to some degree, our fault. Noticing your life, reflecting upon it, considering how you can live it well, wondering how you can do good: These are perhaps the most valuable things that a liberal-arts education has equipped you to do. A liberal education demands that you live self-consciously. It prepares you to seek and define the meaning inherent in all you do. It has made you an analyst and critic of yourself, a person in this way supremely equipped to take charge of your life and how it unfolds. It is in this sense that the liberal arts are liberal — as in liberare — “to free.” They empower you with the possibility of exercising agency, of discovering meaning, of making choices. The surest way to have a meaningful, happy life is to commit yourself to striving for it. Don’t settle. Be prepared to change routes. Remember the impossible expectations we have of you, and even as you recognize they are impossible, remember how important they are as a lodestar guiding you toward something that matters to you and to the world. The meaning of your life is for you to make. I can’t wait to see how you all turn out. Do come back, from time to time, and let us know. 2008/9/18 chrome源码分析之0, RTFM让我们在钻进代码之前先RTFM, 以下内容多翻译自官方文档,几个流程图也是网站上直接找来的,原文地址在http://dev.chromium.org, 不知为何被GFW了,请自行跳墙或用tor. 在chrome comic book和大量的发布和评论文章与官方视频中都提到三点显著特点, 其一就是多进程的模式。 在John Reigh同学的最近博文http://ejohn.org/blog/google-chrome-process-manager/中提到,ch 从google和baidu的人身上知道了一个事实,就是程序难免有bug,再聪明牛B的程序员也只能减少而不能根除这个问题,所以更多的时候,与其多花80%的精力来完善每一个细节,不如在追求完美的设计和编码的同时,拥抱程序可能出错的事实,像google一样在这上面做到了极致,知道再多的测试再牛的鲁棒也会有时crash浏览器,那么我们怎样给用户最好的感受呢,不让一个坏的crash影响其它的页面浏览,方便的杀掉crash掉的页面或者插件。 其二就是v8, 超级快的javascript engine 在这个视频中http://www.youtube.com/watch?v=hWhMKalEicY ,还有http://code.google.com/apis/v8/design.html V8的主要设计师Lars Bak大牛同学深入浅出的讲解了v8 engine的三个最核心的优化速度的地方。 1,使用hidden class,使得property access不用通过代价相当高的dictionary lookup,并且可以使用经典的基于类的优化,比如inline cache, 大大提高property access的速度 2,javascript代码在第一次执行时就被编译成machine code, 而不是中间的byte code, 不需要解释器 3,使用分代的高效的垃圾回收机制
第三就是在sandbox中的render和browser分离机制 chrome的安全机制是其最出色的部分之一,也是我认为目前在port mac版本和linux版本中遇到的最大问题。他的sandbox机制是之前买的一个公司在windows上做的一种隔离和限制进程权限的机制,完全依赖OS的安全机制。 更多的关于sandbox 和 The Security Architecture of the Chromium Browser
上面的架构图能够看出,chrome大体上可以分为两个功能部分,一个就是browser, 另一个时renderers,他们通过IPC进行交互,在renderer这边的RenderProcess对应browser中的RenderProcessHost,RenderProcess管理这的RenderView对应browser中的RenderViewHost. 这里面有些重要的细节,例如共享render process, sandboxing the render, 以及内存不够时如何管理renderers。
Chromium如何display页面 显示页面,基础设施包括下载页面和图形引擎库,首先页面下载由 页面由renderer发起IPC请求到browser, 在ResourceDispatcherHost然后分发到各个URLRequest线程去fetch回来,这一系列的分发中保持一个request ID所以能够正确的返回到发起的renderer这里。 图形引擎使用Skia graphics library,最初是给Android开发的一个跨平台的图形库。代码位置在/third_party/skia. 图形操作入口在/webkit/port/platform/graphics/GraphicsContextSkia.cpp. 更多的代码目录结构在 页面fetch回来以后, 页面的layout就交给WebKit了,google做了一个webkit的port, 做了一个glue层来做adapter, 所有的chromium的操作都是通过这个glue的API来和webkit交互的 The render process renderer中最重要的class是这个RenderView, 在/chrome/renderer/render_view.cc,一个object对应一个网页,负责处理browser发来的navigation相关的命令。 The browser process browser进程包括两个部分,一部分底层的I/O thread, 和RenderProcessHost, 一部分是高层的RenderViewHost和WebContents展现对象。 browser中,在主线程初始化RenderProcessHost的时候会创建这个IPC::CHannelProxy, 它在I/O thread里面跑着,监听到render的命名管道(named pipe), 自动把UI thread上的消息forward到RenderProcess上去。 注意到这个ResourceMessageFilter了吗,它是用来过滤掉那些可以直接在I/O thread上处理的消息,其它的消息会被forward到对应的处理地方去。 这里http://dev.chromium.org/developers/design-documents/displaying-a-web-page-in-chrome#TOC-Illustrative-examples 可以看到细致的如"set cursor"和"mouse click"事件的生命周期都是如何的,怎么在browser和render各层之间传递的。 最后,是我们dive into source code前的最后一站,Getting Around the Chromium Source Code social今天借google的光去桥咖啡参加opensocial的聚会活动 上次facebook的北京活动没去,后来看大家在校内海内上的反馈都很好,有些小后悔 今天去的人挺多,开始说了说天涯,一起和聚友myspace中国的开放平台的情况 相当的boring。。。 后来大家自己social 王兴去了,和他没聊啥,给他提海内之前有时图片server不响应的问题,还有海内open平台的进展情况,他还是比较有趣和open的,所以很多人找他聊 myspace中国介绍了一下他们,给了一个官方的用户数和月PV和用户,相比校内,51,myspace的流量还是太低了 见到天涯的技术负责,InfoQ中国的主编,赞了一下InfoQ, 他们还是办得很不错的,比CSDN和JavaEye更吸引我 发现AOL在国内居然有office,就在清华科技园 自己一个人去的,又不太会自然的open a conversion,所以早早就出来了 也许是性格使然,也许是做技术多了,发现自己越来越孤僻了 别人一和我说上技术,就开始倾诉狂一样的说个没完 碰到其他的时候,就不知道说什么了,很无聊很尴尬 这个social party就是给大家提供一个平台互相认识,给用open social的平台一个展示的机会,给google一个宣传open social的机会 但是,相比校内和那次facebook的活动(据说活动上很多人关注校内),影响力还是差很多 最近也涉及到一些这方面的应用,自己还没有什么很好的想法,而且又很爱打击别人的想法,所以有些烦躁 自己应该多往“我能做什么,如何做好”考虑,而不是消极的“这事成不了,这想法没前途” 和这个party一样,我的社交能力太差了,认识的人少,自己也不能成为别人眼中"有趣的人" 另一方面,就像那天想了很久laser tag的想法,真的有一种能够做的更好的可能,但是这种依赖不止是代码的东西的时候,自己的能力是那么的有限,信心是那么的差 所以假设我现在资金充足,我也不知道我有多大的信心具体实施我的想法 2008/9/17 镭射战场 the laser tag war镭射战场Laser tag起源于欧美,现在已风靡全球。详细介绍有兴趣可以看wikipedia上的文章,http://en.wikipedia.org/wiki/Laser_tag 。在热播的美剧”How I met your mother”(老爸老妈浪漫史)和”Cashmere Mafia”(女人帮)中多次出现laser tag的游戏场景,可见其在北美的受欢迎程度。 我之前和同事们去玩过几次,有在红螺寺的红色基地,也有在香山脚下的某某训练营。今天和同事在车库走的时候发现,车库的环境也非常适合玩laser tag(国内俗称”真人CS”), 之前也想到过可以在更多的环境中开展,并且我参与的3次中大家对整个游戏的兴趣异常的高涨,但是犹豫硬件设备和运营上的问题,总是爽中掺杂着不少的遗憾。 经过一晚上的baidu和google, 找到两个有特点的例子来进行比较, 一个是总部在加拿大的公司Laser Quest, http://www.laserquest.com/,公司看起来很不错,从内容和外表都不怎么好的网站上确有一点很不错,他们很清楚的阐明了公司的Vision和Mission和他们是如何一个公司,运作一个什么东西。以下来自http://www.laserquest.com/,网站做的比较糙,但是公司的信条和对员工的态度很好,他们是”创造快乐”的地方,所以他们的员工也是他们的顾客,在公司将所有员工快乐工作,团队和个性培养作为一个很重要的角度去做。 Company Vision To build a World Class organization that provides an outstanding entertainment experience.

我认为这个公司的不足和可以改进的一些地方, 1,用户群单一,基本上都是一些公司team building的选择 2,推广和运营方式偏传统,过分依赖会员制和大量的优惠政策
整个市场存在的几个核心问题1,设备陈旧问题多,人流量少,盈利少更更新不了设备,带来恶性循环 2,用户群过于单一,除了公司building, 在学校和小孩子中推广会有更大的市场 3,场地效率低,导致单位时间每个消费者费用过高 4,场地多在便宜租金的荒林中,形势单调 5,军训氛围严重,效率不高,导致用户对组织者的反感 6,运营推广效率差,没有进入很2的WEB 2.0时代,论坛内发展新用户效果不好,大多来自搜索引擎和朋友推荐。 If I do this0, 像Disney学习,带给大家欢乐,用这种交互,公平竞争的,锻炼团队协作的特殊方式和风格 1,跟进最新的技术,改善设备水平 2,开发更多的场地利用率和组织水平,使用户娱乐中fun的成份更多 3,精益的方式来降低成本,已更低的价格带来更好的体验,来管理运营过程,保证用户的have fun 4,市内游乐场,经营不善游戏厅(在崇文门新世界和其它一些地方看到几乎没什么人玩)的地方开发室内的场地,计时,可以自己组队和按时间像看电影一样然后临时组队的方式,提高场地利用率。 5,更多利用互联网的宣传渠道,鼓励口口相传的推广 And beyond在交互中带来快乐,用科技来拉近距离
最后摘抄一段laser tag的 PLAYERS’ CODE I will not run, climb or jump. I will not sit, kneel or lie down. I will not cover any sensors. I will not use offensive language. I will not make physical contact with other players.

世界顶尖运动队教练的成功秘诀作者 Urs Peter译者 郑柯 发布于 2008年9月4日 下午8时54分 上周我参加了一门有关教练的研讨会,其中有荷兰女子曲棍球队主教练Marc Lammers的主题演讲。在世界杯的历史上,这个团队是最成功的,曾获六次冠军。在听演讲的过程中,我意识到为什么这个团队可以取得如此卓绝的成就。她们的成功,在很大程度上,要归功于教练 Marc的执教方式。Marc Lammers发现了可以令团队释放全部能量的秘诀,大家不仅像一个整体一样齐心协力,每个人作为团队的一份子也各尽所能;而这一切都以意想不到的方式发生。我的的确确得到很多启示。本文总结了他发现的原则,并描述了这些原则如何应用到软件开发之中。 我本人作为一个Scrum Master,发现他揭示的原则可以在我自己的Scrum团队中使用。原因在于,这些原则从本质上适用于任何团队,无论这些团队是装配汽车、打曲棍球或是开发软件。本文中,我希望分享一些Marc Lammers在研讨会中提供的执教秘诀和经验,并说明如何在每日的Scrum和项目实践中使用这些知识。也许,即使有了它们你也无法获得世界杯,可如果不注意使用,团队的所作所为也许会令你和客户大跌眼镜。 原则1: |
