韩寒与方舟子

2012年春节最有意思的话题就是韩寒和方舟子之争。这场争论波及范围之广,有用信息之多,都是近年来少见的。现在把这两天自己所看和所感做一个简单的总结。

方韩之争的背景起源于韩三篇,方舟子在一开始并没有参与到那场争论中,而是在麦田质疑韩寒blog为枪手所写之后卷入。之后麦田因为某些原因退后,方舟子成为主力,各路神仙大佬纷纷卷入,有些同学不幸中弹(比如海岩)。这场争论包含的问题很多,但方始终瞄准于一个简单而又复杂的问题:韩寒早期的作品是否真正出自韩寒之手?。需要注意的是,方和麦田的质疑点是不一样的:麦田质疑的是韩后期的blog,而方瞄准于早期的作品,特别是韩的发家之作。这是因为麦田的质疑存在诸多漏洞;但方火眼金星,发现了韩早期作品的诸多疑点。

至此争论变得简洁:韩早期的作品是否存在代笔的嫌疑,特别是其老爸?争论从方韩二人扩散之新浪微博上的各位达人:有娱乐界的(比如姚晨),有媒体界的,有出版界的,有经济界的,有科学界的,以及其它等等。双方各有支持者。首先记录一下我自己对这场争论的一些观察:

  • 大部分表态的作家和娱乐明星支持韩寒。部分媒体工作者也是如此。
  • 理科生和经济学家支持方舟子的多。当然他们也不是完全支持,提出了不少方质疑中的弱点和错误。
  • 方一方的论述多具体在细节。韩一方往往上升至民族大义,自由权利。认真回答方质疑细节的不多。
  • 不少文字工作者反对一切针对著作权的质疑,而且乱用比拟和比喻来证明方的荒谬。
  • 不少人讨论到著作权到底是只是证实,能不能证伪的问题。
  • 目前只见到安替发出的关于"静静的顿河"的国外分析案例。
  • 纸质媒体明显偏向韩寒。网络媒体中网易列出了双方的论据。腾讯貌似偏向韩寒,但后来专题被删。Sina,sohu未见相关专题。
  • 前两天韩寒高调宣称要去法院起诉方舟子侵犯名誉权。"正常人士"都认为韩寒的起诉是毫无道理的。不正常人士则认为方的做为已经超出了言论自由的边界。

目前来看方舟子暂时没有所谓的“铁证”,但发现了不少"弱证据"。这些“弱证据”首先让韩寒自愿或者不自愿的承认自己曾经大量阅读书籍的经历(此前韩曾说自己从不或很少阅>读书籍),然后揭露了韩寒一方内部诸多前后表述不一致的地方。这带来的直接后果是韩寒一方的诚信是很值得怀疑的,以及早期参加新概念作文比赛时是否存作弊的疑问

有些人认为除非代笔者自己承认,否则方永远都无法找到确切而充足的证据。这条结论也许适用于其它类似问题,但韩寒代笔的案子有其一定的特殊性。方质疑的主要著作是韩早期的《求医》,《书店》,《三重门》和《杯中窥人》。方的主要怀疑是:1,如何解释文中大量出现的掉书袋引用。2,很多情节不像17岁少年体会而是40岁中年人的亲身体会。对于第一点韩给出了解释,但无法让人信服。很多人认为方质疑的第二点有问题:作家是可以虚拟出非自我经历的情节。我不这样认为:情节是可以虚拟的,但情节中的技术细节确必须来自知识。这知识可以是自我经历,也可以是资料查询的结果。比如你可以不会开飞机,但如果你写了一段开飞机的情节,飞行员读了都觉得很真实,然后你宣称自己从未参考任何资料,这就有问题的了。我想这就是方质疑的关键所在。

方韩案给我的启示之一就是:你可以讨厌中国的教育体系,但你必须尊重和承认知识(李敖对韩寒也有类似的评论)。目前国内有一股读书无用论,希望方韩案能让我们重新思考>这个问题

why we need single quote for awk

Today I need to use awk to add extra tabs and space to a long file. Then my first awk script begins.

awk is simple: /patter/'{action}'. You will see nearly every on-line introduction will tell you to add single quote to include actions. Sometimes single quote behavior is really strange in windows, but works well under Linux.

FinallyI realize single quote must be used to preserve bash to expand some special characters,like back-slash and stars, and pass them to awk. In Windows, dos/cmd has the different ways to do it, then you need different quote, see http://www.catonmat.net/blog/wp-content/uploads/2008/09/awk1line.txt for example.

Innovation

I am holding a whole day meeting to discuss about innovation. People talked a lot about it, but I am still not satisfied about it and have questions:

  • What actions do we have to archive our idea about innovation.
  • Do we really understand what innovation means?
I have some thinks about innovation. From my understanding, sometimes we misunderstand the difference between innovation/improvement/invention and others things. Innovation is a beautiful word, but what really does it mean?

For company, right product strategy is always more important than "innovation". What kind of product do you want to build? Then comes how to build this product with innovation idea.

Default action for SIGHUP

Q: Why program is killed if I log out the bash and why it survive if using nohup?

A: When log out, the bash will generate the SIGHUP to progress attached to it. If there is no default routine in progress to handle this signal, kernel will use the default action (terminate for SIGHUP).

Why RSS fail

Recently I just realize how good the RSS did. By using RSS, you have kind of information center to read all interesting information from different site and it is a good idea. It is similar with email but only with one direction.

But seems RSS is not popular any more, we talk with twitter, facebook, G+ and many others. But why not RSS.

This is a interesting thing and worth to think.
