few facts on the Rape of Nanking

The following are not all correct, but interesting enough to read as a fresh perspective of view.

  • The Rape of Nanking was a horrible event, but you'll find few Japanese that deny it nor didn't study it. The massacre is required reading and studying starting at all the thousands of middle schools in Japan except for 10 private schools which are run by ultra-right wing Japanese neo-conservatives. They are essentially the KKK of Japan and represent less than 1% of the population.
  • Iris Chang's "The Rape of Nanking", although best known, is also filled with factual errors as she is not a trained historian. Pro-China experts on the topic says she did more harm than good. She gets holidays, events, and other easily verifiable dates wrong again and again. Many of her sources are questionable and proven false. However it is the most popular contemporary book on the massacre in the last two decades. Chang also had a difficult time differentiating the tiny right wing fringe Japanese with the rest of normal every-day Japan. As a result her characterization of the Japanese is accepted as fact by many Chinese and became added fuel for hate against the Japanese to a point where it is commonplace in China today.
  • Japan's top leaders have apologized dozens of times (at least a dozen from the various Prime Ministers and the Japanese Emperor himself) for the Nanjing massacre and comfort women, and offered huge reparations which China accepts every year (the money but not the apologies).
  • Japanese descendants of Imperial Japanese soldiers involved in the Nanjing massacre have independently, but quietly, offered over a million in USD to each of the Nanjing victims with no strings attached.
  • Japan has more experts on the Nanjing massacre than even the Chinese. Most of them have a much higher estimation of those victimized in the massacre than the Chinese experts. (This one was a shock to me as I'm ancestrally Chinese and was told otherwise)
  • The Nanjing Massacre is a mixed sorepoint for the Chinese Communist government because it gives sympathy for the Chinese Nationalists (who were in power over China at the time).
  • Chiang Kai Shek ordered a firebombing of Nanking that actually killed far more people than the Japanese but no one cares because he's Chinese and sadly it seems "Chinese on Chinese murder doesn't count". This was a terribly failed bid to thwart the Japanese and killed only a few Japanese soldiers but scores of Chinese. Chiang always blamed the Japanese for the firebombing but evidence from two decades ago squarely proves it was Chiang.
  • The Russians did worse by raping far more women and children and mass murdering when sacking Berlin during WW2 but few middle-school textbooks report this around the world (presumably because it would lend sympathy for some Nazi Germans).

The true disastrous country which do real harm to China is Russia and Japan.

DARPA资助的Zebra Imaging™全息显示技术也太科幻了吧。。。OMFG

est跪求光学大牛来解释下原理。。。。

(视频如果没法看就是优酷还在审核。。。耐心等下吧。)

youtube原始视频12

目前似乎只是一个塑料片,Zebra Imaging™提供打印服务。把电脑上3D发给Zebra Imaging™,付款,然后就收到这个全息立体板。也可以去买一些附件,例如灯光设备之类的。

官方网站介绍说动态显示现在有prototype能几乎做到real-time display了。

太牛了 orz

这个塑料可以弯曲,est在yy把做成一个球形,然后人在里面或者外面看。。。。。。orz。。。orz。。。微软Surface发来贺电。。。。

Zebra Imaging™的技术有下列要点:

  • 可以scale到无限大面积
  • 数字化Imaging
    Zebra holograms are composed of 3D holographic elements (hogels) that are the holographic equivalent of 2D pixels
  • 黑白或彩色
  • 全角度Parallax
  • 100°视角范围
  • 快速大量拷贝能力
  • 可以把物体投影到悬浮空中
  • 无需任何眼镜、特殊观看设备和观看技巧,直接在光源下就肉眼可见
  • 60cm长宽的全息图,可以产生前后各30cm的立体感深度
  • 便携。材质可以卷曲、透明、半透明
  • 可以同时多人从不同的角度观看全息立体图(est注:这个就比今年CES上那个需要摄像头跟踪人脸的3D电视牛逼多了)
  • 支持多帧、多频道动画,例如气流、切割前后对比图等。
  • 最佳适用场合:visualize designs, communicate ideas, show prototype models, and map terrain.

Multi-viewzone viewing example

From this post.

#5. They are a straight up pain in the ass. They haven't held down any previous jobs for more than 6 months and they don't know what the fuck they want from life. Be warned, I have been one of these people and they will cost you an arm and a leg in terms of wasted time and productivity.

  • frightening intelligent, analytic and philosophic -> most things were simply too trivial to entertain him for more than a week
  • well-paid freelancer for ~15 years -> absolutely no financial motivation

[zz]抛硬币连着9次背,怎么理解第10次还是背、面各50%

发信人: UniLotto (民科在水木), 信区: Mathematics
标 题: 抛硬币连着9次背,怎么理解第10次还是背、面各50%
发信站: 水木社区 (Fri Feb 12 12:46:27 2010), 站内

知道这个理论上的结论,但是还是很难从直觉上感觉到。
另外,如果以后是正反各50%,nna那么,岂不是总数上最后多了9次背。
再一次就这个月经贴请教大家,见笑了

发信站: 水木社区 (Fri Feb 12 15:19:24 2010), 站内

抛开理论 仅凭直觉解释的话

因为你没有统计你在这九次之前历史上你曾经抛过多少次硬币 或者这个硬币在倒你手上
之前被抛过多少次 或者在你抛的同时有多少人也在抛同样的硬币 更不知道这么多次的结

因而你所说的9次背相对于上述的无数次实验来说忽略不计了 毫无意义

高人很多啊,感谢大家。

看了《赌客信条》,上面的问题似乎是开放的

赌客谬误

小数法则的经典表现就是“赌客谬误”。

李太太一连生了五个女儿。

李太太:希望我们下一个孩子是男孩。

李先生:亲爱的,都生了五个女儿了,下一个肯定是儿子。

李先生对吗?

众所周知,掷硬币正、反面出现的概率为50%,在掷硬币游戏中,如果前几次大多数
出现正面,那么很多人会相信下一次投掷很可能出现反面。这就是赌客谬误(gambler?
蒺s fallacy),也是很多赌客信心大增的原因。

赌客谬误的产生,是因为人们错误地诠释了“大数法则”的平均律。投资者倾向于
认为大数法则适用于大样本的同时,也适用于小样本。

赌博是随机事件。

一枚硬币,连出三把都是正面,那么下一把出反面的概率仍然不会大于50%。

从理论上讲,硬币也好,骰子也好,既没有记忆,也没有良心,概率法则支配一切


随便到一家合法的赌场,就能看到这种赌客“猜反正”的现象:

连输几次就该赢了

连出几次红就感觉该出黑了

连出几次庄就以为该出闲了

连出几张小牌肯定该出大牌了

……

这是很多赌客感觉能战胜庄家的理论依据,甚至很多有学问的赌徒写的“赌经”,
都明显带有这种错误。

你可曾见赌客拿本子记录百家乐出闲和庄?赌瘾甚至可以让一个天资平庸的赌徒变
成统计学教授。

连抛100下硬币,会一直出正面吗

在《黑天鹅》一书中,作者尼古拉斯?塔勒布向两个虚构人物请教一个问题。一个是
“肥佬汤尼”,一个粗俗的,靠投机钻营致富的家伙,一个是博士约翰,一位诚实的学
者。

尼古拉斯:假设硬币是绝对公平的。连续抛出99次,每次都得到正面。我下一次得
到反面的概率有多大?

约翰博士:“超简单!当然是50%,因为你假设硬币是绝对公平的。”

尼古拉斯:“汤尼,你认为呢?”

肥佬汤尼:“很显然,不会超过1%。”

尼古拉斯:“为什么?我最初假定硬币是公平的,每面都有50%的概率。”

肥佬汤尼:“这游戏是不公平的,这枚硬币里一定做了手脚。谁相信所谓“50%”的
说法,他要么是个草包,要么是个大草包。”

尼古拉斯:“但约翰博士说是50%。”

肥佬汤尼趴在在尼古拉斯耳边小声说:“我在银行当保安的时候,就曾经和这类傻
瓜做同事,你可以利用他们赚大钱。”

肥佬汤尼认为,在硬币连抛99次,每次都得到正面的情况下,绝对均匀的假定是虚
构的。而约翰博士的回答可能代表了教科书的标准答案。

在某个聚会场合,笔者曾向朋友 Jay 请教过这个问题。

一枚绝对均匀的硬币,绝对公平地掷出。连续99次都是正,接下来要再掷出一次,
你认为出正的概率大,还是出反的概率大?

A.出正概率大

B.出反概率大

C.各占50%

Jay是英国某著名大学的计量金融学博士,他很谨慎地选择了C。

此时,另一位朋友插进话来,非常确定地选择C。

笔者问:“为什么呢?”

这位朋友说:“因为我是教统计学的老师,并且这种事件,历史上真的曾经发生过
。”

笔者:“那些钱币应该是两面都是正吧?”

教统计学老师:“嘿嘿,是的。”

这位讲师朋友所谓的曾经发生的事件,是一般概率课上都会讲到的一个典故。

宋朝大将狄青受命平叛。当时朝廷中主和、妥协派势力颇强,狄青所部亦有些将领
怯战。

狄起兵祭旗,他手捧100枚铜钱,对众将士说,如果我扔下的100枚铜钱都是正面朝
上,则必定是上天恩赐,让我们大胜而归。

许多将军都劝狄青不要这样做,狄青坚持。当他把100枚铜钱扔到地上时,众将士都
不相信自己的眼睛,奇迹发生了,100枚铜钱全正面朝上。于是,士气大振。

狄青令人将100枚铜钱钉在地上,派重兵把守,若有人翻动铜钱,格杀勿论。

当狄青获胜班师回朝,把铜钱收回时,有一些将士才发现,这100枚铜钱两面都是正
面。

理解了赌客谬误的人,会不会浑然不觉地犯一种“学者的谬误”呢?这同样是一种
“小数法则”。

假设在某个场合,一个陌生的美女邀请你猜硬币。她让你猜,抛一次硬币会出现反
还是正?赌注为100万元。

她发誓,她递给你的硬币是绝对均匀的。

你将信将疑地看着这位美女,怎么证明她的话是实话呢?

你说,在赌博之前先抛10次先验证这枚硬币。

于是在你连抛了9次硬币,结果,这枚硬币9次正面朝上。

你不干了:“这枚硬币一定是动了手脚!”

这个陌生的女人又递给你一本统计学教科书,书上说,抛10次,9次朝上,这种不平
衡的结果发生的概率还是比较高的。

尽管你的疑心加重了,但你还是相信教科书不会错的。

于是,你要求再抛100次硬币来检验。

你抛了99次,每次都是正面朝上!

这本统计学教科书又告诉你,100次抛掷中99次正面朝上的可能不是没有,但其概率
是如此微小,以至于你费了好大劲儿才数清小数点后零的个数。

那么,你会和她赌吗?

如果赌,你赌正面赢,还是赌反面赢?

如果你赌正面赢,其实就等于认为这个硬币出正面的概率大,你冤枉了一个从理论
上讲是诚实的女人。

主要是上面一个解释很独到。。。非常喜欢。虽然又是滥用无穷大和未知的一个小花招。

Why manuals, FAQs and long articles suck

Followed by my previous blog post on Epistemology

Why people are reluctant to read TFM or TFA?

Let me give you an example. Google just announced Google Chart Tools, which looks fine to me, so the front page describes two kinds of charts: Image charts and Interactive charts, and blah blah blah pros and cons about choosing, and yet it links to their standalone blah blah page. Their separate page describes how to generate a chart, by adding epic long list of URL parameters.

So if you are about to use the Google Chart API, you have to read through their manuals, think about your goals, and interpreting them to a URL construction process, and viola your Chart is here.

But My questions is: do people really have to read a long and stupid post to make a chart?

Why can't we have a step-by-step, or a parameter tweaking GUI, like those we use in MS Office Excel?

The real stupidity lies in the difference of Procedural knowledge and Descriptive knowledge. Google Chart API manuals sucks, because the API authors translate a procedural HOWTO to a long and boring descriptive article, which I call it compiling. Now if a user wants to make a chart by Google Chart API, he has to translate it back to procedural practice, which takes a lot of time to decompile and shit load of extra effort to become proficient with this kind of work.

It's the same with FAQs. People seldom look into FAQs, but often ask more. Why? Because people are more willing to get to know how directly instead of know that. The future of FAQs, is to translate the Frequently Asked procedures into a formal semantic logical database, then a NLP frontend chat program to answer people's questions interactively.

However there's a useful aspect of the difference, if you want to make something deliberately hard to understand, you might want to translate it to descriptive form. From my personal experience, if Cisco books were too easy to understand and implement, the Internet would be more chaotic and messed up. Every netadmin and ISP would make some kind of modification and customization out of standard protocols, which eventually and ultimately makes the Internet un-inter-connectable.

tl;dr manuals, FAQs and long article sucks because the they fail to notice the huge difference between Procedural knowledge and Descriptive knowledge.

Epistemology

Reading through wikipedia on Epistemology is kinda fun

belief is what we take for granted, truth is what can be used for a successful predict, knowledge, is comprehensible truth.

declarative knowledge == spacial knowledge

imperative knowledge == time knowledge

imperative knowledge is just an instance of declarative knowledge, which means IK∈DK. Because time+space can always be represented in a phase space. But it's obvious that IK is faster to run because it's often remembered in the simplest form. no one likes to remember the harder procedure alternative version of an IK. If the situation matches exactly to what you previously remembered IK, it's just mirror those knowledge to actions with little effort of thinking. If you know DK only it will take you a lot more time to extract and construct knowledge to a useful form.

Network effect

今天的proggit上讨论了为什么github比bitbucket流行。学到一个词语:Network effect

电话公司,腾讯QQ,MySpace打败friendster都可以归纳为network effect。 其他微博永远也没法赶上twitter,永远没有超过Facebook的SNS,也是这个道理。

如果说商业战术是线性竞争,那么一旦有了network effect,这个竞争就有点类似场的扩张和辐射了。。。

Buzz是个人肉社工的好入口。。。

Google Buzz最大的问题就是只能hide,不能delete这个service,甚至Dashboard都不会显示你Buzz了什么。

其次有个很严重的个人隐私泄漏,那就是你的Google Public Profile会悄悄的显示你的full name和默认显示你的full contact list。赶快取消掉下面两个选项吧:

  • Display my full name so I can be found in search

  • Display the list of people I'm following and people following me.

不过神奇的是我的马甲Gmail都有了G Buzz,主力Gmail居然没有,所以我决定坚持用IMAP收邮件,坚持不开启主力帐号的G Buzz。要跟世风日下的Google总部死磕到底。

我希望Gmail就是一个单纯的email工具,不要弄成五花八门的跟国产软件一样。

G buzz的splash界面下面有两个可以点的地方

点击这两个都会开启buzz。强买强卖

测量工具的颗粒性

测量工具普遍都有一个最小精度,当被测量对象超过这个最小精度,就会发生有趣的表现的变化。

下面的系列截图是来自Anti-Grain Geometry的一个demo alpha_gradient。这里的最小精度明显就是屏幕上的一个pixel。出现的纹路貌似叫Moiré pattern

接下来两张截图就很有意思了~~~意外啊意外~~~

以下截图是改变参数得到的另外一些pattern

恩。我在想,假如说这个最小精度是Planck length的时候,观察者那里会发生多么有趣的事情。

禁用wordpress的texturize

Wordpress有一个很脑残的功能,把半角引号自动替换成全角的。我一开始也以为是CSS做的。折腾了半天没结果。原来这个功能叫Texturize,是在wp-includes/formatting.php里实现的

网上找到一篇教程,如下修改代码:

// static strings 
$curl = str_replace($static_characters, $static_replacements, $curl); 
// regular e-xpressions 
$curl = preg_replace($dynamic_characters, $dynamic_replacements, $curl);

都注释掉就OK了。

Robert Anton Wilson: A Multiplex of Causality

The use of atomic weapons was widely blamed on a primate named Albert Einstein. Even Einstein himself had agreed with this opinion. He was a pacifist and had suffered abominable pangs of conscience over what had been done with his scientific discoveries.

"I should have been a plumber," Einstein said just before he died.

Actually the discovery of atomic energy was the result of the work of every scientist, craftsman, engineer, technician, philosopher, and gadgeteer who had ever lived on Terra. The use of atomic energy as a weapon was the result of all the political decisions ever made, from the time the vertebrates first started competing for territory.

Most Terran primates did not understand the multiplex nature of causality. They tended to think everything had a single cause. This simple philosophic error was so widespread on that planet that the primates were all in the habit of giving themselves, and other primates, more credit than was deserved when things went well. This made them all inordinately conceited.

They also gave themselves, and one another, more blame than was deserved when things went badly. This gave them all jumbo-sized guilt complexes.

It is usually that way on primitive planets, before quantum causality is understood.

It's easy to blame a single reason, because it's easier and we are too lazy to think of those trivial reasons.

est的孔教观

最近看了两篇关于孔教的帖子,加上一些平时听到的论点,我得出一些结论:

  • 孔教的现状,不是单纯学说,而是一种 cult
  • 孔子是被星探董仲舒发现,被汉武帝出资并且成功包装的明星(NewSMTH历史版935813文)
  • 后人在孔子那几首保留歌曲里继续grind出来了不少内涵,在摇摇欲坠的说教体系里打了好几次SP1 SP2补丁。只不过后来被更牛逼的发源于欧洲的体系摧枯拉朽冲毁了。
  • 孔子被看成“圣人”,其实孔圣心目中也有圣人,这个圣人就是周天子。
  • 孔教是对周文化的总结,特别是对春秋西周文明的代表性描述。(秦晖:儒家的命运)
  • est觉得孔教徒是最懦弱无耻的。就算山上的土匪,山下有人冒充他的旗号,山大王都会下来讨个说法。每次人们批判孔教的弊端,孔教徒都会立刻像乌龟一样缩进一个壳里,说,那个不是真正的儒家,于是从龟壳里拿出某个特定版本的《论语》,然后说,真正的儒家是这样如何如何云云。他们的无耻之处就在于无视现实中的孔教作恶危害天下,而用他们眼中的孔教,作为惰于或者怯于维护自己教义的尊严的借口。生活中的儒教徒,大多是以装逼为主,自负书读得多就牛逼,其实他们只是经验主义堆积起来的傻逼。或者是利用性的,用孔教的popular程度来达到个人或团体的一些目的。真正的纯儒教徒是不可能存在的。儒教爱好者和伪教徒却很多。
  • 全世界有组织宗教,还有一点比较恶心就是把一些自然行为归纳到自己门派下。比如在中国,尊老爱幼经常被看成一种符合儒教的行为,被认为是有教化有修养的表现。我靠。。。。就好像哺乳动物都是野蛮的同族相食的一样。。。而且往往人们的行为也被attribute和归功为儒教的力量,这种意识的愚蠢程度跟感恩上帝一样。其弊端也很明显,无助的时候就去教义里寻找不靠谱的帮助和线索,并且臆加猜想。
  • 孔教的内涵就不多说了,孔子本身还是个比较牛逼的人物,有不少可取之处,但是过于吹嘘孔子,就好像孔子之前中原人就没有任何道德准则一样。现在很多人分不清结构性作恶和非结构性作恶的区别。儒fan一直认为儒黑势力很大,是因为他们一直没发现儒fan和儒黑不是互斥的,而是有相当大重叠的。要避免对孔子或其他偶像的盲目崇拜和认可,绕过一切思想体系固有的弊端,唯一的方法是学习的过程中保持critical thinking的姿态。
  • 事实上,任何石器时代的理念都应该进故纸堆了。我觉得现代社会,信息如此发达,每个个体都有自行总结出比原始人水平高的多的思想体系的可能性。est一直有这样一个观点,如果一坨思想体系,学习它的成本超过了创造一个替代品的成本,那么这个思想体系的价值含量是很低的。即使被吹嘘和打广告,其实是促进其贬值的。换句话说,思想也有通货膨胀。如果说对一个体系学习的投资大大超过这个体系所能提供的产出,那么这个体系就是负资产。人类社会有一天会发展到儒教一文不值的地步。所以不要看est黑儒教黑得厉害,那是est关心儒教。儒教拒绝批评,从而发展成新保守主义(Neo-conservative),那也是拒绝了拯救,注定消亡。
  • 说到一个思想体系的消亡,est最怕的就是思想同质化。est觉得儒释道三修就是一种很严重的近亲繁殖同质化。所以est一直选择性忽视传统文化。
  • 孔子在现代中国社会的极端重要性,是因为中国自太祖挂了之后,急需一个能对抗 穆罕默德 和 耶稣 的人物。孔子毫无悬念的再次成为了被包装的标志性人物。从大局上来看,这个被逼的行为还是有益的。但是这个行为肯定会导致思想的陪葬牺牲品。
  • 新文化运动和X革,我是无比支持的,可惜这两场运动都打破了旧的没能建立新的,后果就是连旧的都不如,只有露宿喝西北风了。。。囧。。。。
  • 理性和科学总是不能盖过世俗崇拜的光芒,so, just fucking get OVER it!

sheeple多了,需要一种能 cult 的东西来把sheeple凝聚、兼容、兼收并蓄包含起来,孔教被不幸选中了。就是这样。

硫氰化汞 Hg(SCN)₂ 的受热分解视频。。。太震精鸟!!!

不牛逼的视频我是不会亲自转发到优酷的。。。。

太恐怖鸟。。。让人想起了克苏鲁

上面视频里的反应叫Pharaoh's serpent,俗称Black snake, Serpents in the Grass

Black snake有多种方式,比较温柔的是用小苏打做的,印度就有一个这种烟火表演视频

比较震撼的是用硫氰化汞(视频),英文名Mercury(II) thiocyanate,化学式Hg(SCN)2,剧毒

Hg(SCN)2 is considered to be Level 3 of Health danger by NFPA 704(the max lvl is 4), where level 3 stands for: " Short exposure could cause serious temporary or moderate residual injury (e.g., chlorine gas)." The reaction of Decomposion produces vapors of Hg, wich are very poisonous as well.

貌似是用 (NH4)2Cr2O7, Hg和CN制得视频)的

网上摘抄几段介绍:

(三十二)人造毒蛇 / 毒蛇出洞

用品:400毫升烧杯、玻棒、吸滤瓶、酒精灯、滴管、锥形纸模子。
0.1摩/升硝酸汞溶液、0.1摩/毫升氯化铁溶液、1摩/毫升硫氰化钾溶液、糊精。

操作:烧杯中倒入0.1摩/升硝酸汞溶液300毫升,滴入10滴氯化铁溶液,然后逐滴加入1摩/升硫氰化钾溶液60毫升,直到刚出现红色,经揽拌而不退色为止。用吸滤瓶抽滤得硫氰化汞沉淀,取出晾干。

将干燥的硫氰化汞加入适量糊精和水调成糊状,灌入锥形模子,晾干。表演时,用火点燃锥状物的尖端,就有黄绿色烟产生,曲曲折折而成蛇状。

原理:

硫氰化汞不溶于水,可由硝酸汞和硫氰化钾溶液反应制得,并以Fe3+作指示剂,当溶液变成红色时,说明Hg2+已完全沉淀,如果硫氰化钾过量,硫氰化汞则会生成络合物而溶解。

Hg2+ + 2SCN-=Hg(SCN)2

硫氰化汞受热易分解,且体积膨胀很大,曲曲折折生长成蛇形。 其化学反应大致如下:

4Hg(SCN)2 heat 4HgS + 2CS2 + 3(CN)2↑ + N2
(CN)2(氰)为剧毒气体。

说明:硫氰酸汞,又名硫氰化汞、硫氰酸高汞、硫氰酸汞(II)、硫代氰酸汞、硫氮氰酸汞。英文名称:Mercury(II) thiocyanate。英文别名:mercury dithiocyanate;Mercurythiocyanate。化学式:Hg(SCN)2。分子量:316.75。白色粉末,几乎不溶于水。难溶于盐酸、乙醇、丙酮。能溶于氨水、乙醚、硫氰化钾及铵盐,易溶于浓的碱属硫氰酸盐溶液中。露光变色。熔点时分解。有毒。主要用于照相业。

注意事项:硫氰化汞燃烧产生剧毒物质,硫氰化汞本身也有毒。实验应在室外或通风橱中进行

Flash的开放和不开放

我们说Flash基本上是完全开放的架构了,.swf的格式,各种通信协议,Flex,等等,基本都是开源的。但是今天还是看到一些不完全开放的细节:

  • Flash Player不开源。官方说原因是Flash Player里H.264的License规定不能开源
  • Adobe用DMCA去把在sourceforge上的rtmpdump强行取下了。
  • RTMP协议的handshake一直没写,而且每次Flash Player升级这个握手协议就要变,逆向出来的山寨Flash Media Server就不能用了
  • Flash Player规范里没有Pixel Blender部分

总的感觉Flash Player没开源还是有道理的。Chrome和Chromium的区别就是,Chromium不支持H.264的HTML5 Video,也不支持Bookmark Sync,因为Bookmark Sync里有Google的proprietary code,所以Chromium里只有个stub。Chrome不是开源的浏览器,开源的是Chromium项目。,其实Windows下那个Google Talk单exe客户端本来开源的,我跟Google的开源主管沟通过,因为有个GlobalIPSound的模块,所以不能开源。不过现在Google Talk改用Speex了。
