Mixxer- mixes the languages

better day introduced Mixxer to me two months ago, and I have seen some Chinese bloggers discussing it recently.

Mixxer is a free matching system for language learners and teachers. It focuses on the skype users. It currently has near 3000 registered users.

The Mixxer’s UI is simple and intuitive, but it needs a rating system to help learners choose teachers. It is necessary to have a feedback and evaluation system too.

As some learners wrote in their profiles, they are willing to pay for a teaching service, but the Mixxer completely leaves the entire payment process to the users. It does not incorporate any on-line payment system to help the users in the money issue.

Mixxer is most probably setup for non-profit purpose. It is understandable that Mixxer does not have such commercial feature (nor does it have any annoying ads.)

However, should Mixxer be commercialized, how to cash in on the educational matching service would still be its biggest issue. Until now, we have not seen one successful business model for consumer e-learning in the market.

Internet is good for short-term tansaction; learning is a long-term process. These two things have a conflict in their natures.

The one who comes up with the first solution will rule the consumer e-learning market.

教育技术资讯介绍了Mixxer——寻找用Skype交流的外语学习伙伴

Mixxer是一个免费的教育网站,为语言学习者和教师寻找语言交流的伙伴。“语言伙伴”被定义为:某人的母语是你要学习的外语,对方同时也在学习你的母语。寻找这样的伙伴交流就是本站要为语言学习者提供的服务。这样建立伙伴关系的双方可以通过在线互相帮助对方学习外语。除了个人伙伴外,网站也为教师提供发现班级伙伴的服务,这样不同语言的两个班级就可以互相帮助对方同学学习外语了。

的确,Mixxer提供了一个不错的学习语言的配对平台。

播客宝典在Mixxer—-用Skype和老外学外语还提出了一个有意思的构想:

如果能解决付费问题(Google checkout?),Skype还可以是个很好的网上私塾平台。

付费问题是困扰远程教育商业化的一大问题。我们已经有了比较成熟的付费工具,但缺乏可行的远程教育商业化模式。

就拿Mixxer来说吧。如果Mixxer商业化了,怎么赚钱呢?

最有可能的是把用户具体联络资料隐藏起来,要给钱才能看。但好的老师一旦有了点名气后就会离开,不再需要Mixxer了,因为一个人能教多少时间多少人基本上都是很有限的(在Private Tutoring的范畴),大量的广告或配对并没有好处。长期下去,留在Mixxer上的老师不会是高素质的,那么一旦收费Mixxer就很难有长期收益。

better day讨论了很久了,但是大家都没有什么头绪。

Nuvvo是一个另一个很好的尝试。它允许教师上传课件,并帮助教师收费。但到目前为止还似乎不大成功。

八卦丘-田事件 1 Gossip about Qiu-tian incident 1

想不到维基百科上那么快就有人把丘-田事件重新整理了,看来有很多人关心这件事情。

如果北大教授丁伟岳项武义炮轰丘成桐讲话实录是真的,那么这件事还不只是几个大腕吵吵架那么简单,还牵涉到国家几亿元的问题。

把维基百科上的文字转摘过来,补充了几个链接,而且还加了本地链接。

For your own safety – beware of Chinese net-ware

Nart Villeneuve has discovered that Skype’s partner in China, Tom Online, has implemented filtering of Skype’s text chat for Chinese users without informing them.

Actually, that is not a surprise to me. According the recent Yazhou Zhoukan‘s interview with Mr. Feng GuangChao, a Chinese internet safety expert, the Chinese MSN messenger and QQ have such good feature. (I wonder the Chinese Yahoo messenger does not fall behind in this game either.)

Mr. Feng also suggests not to use free Chinese web mail services, such as Sina.com, 163.com, or Tom.com, because all of them have implemented self-censorship in scanning the e-mails.

Furthermore, if you want to have a better privacy when you are surfing net in China, Mr. Feng advises to use encrypting proxy service such as Freegate.

Here is the list of software or services Mr. Feng recommends to use for a safe internet experience in China,

email     Hushmail      www.hushmail.com

即時通訊(IM)   Gtalk       www.gmail.com(在gmail中即可開通)

網絡電話(IP phone / Net phone)   Skype       www.skype.com(非TOM.com版本)- Not the Tom.com version

防火牆(Firewall)  Blackice      www.blackice.com

加密代理(Proxy server)   自由門、花園網等   www.dongtaiwang.com

播客宝典的国外的月亮和中国的月亮很有意思。他提到Skype的Tom版本自动加载了聊天文字过滤器。

国内软件商确实是用心良苦,照顾周到了。

再读读以下亚洲周刊的专访,道高一尺,魔高一丈。

话又说回来,中国那么大,要真正的全部封锁还确实不容易。我很多朋友在中国就都能够访问到wikipedia.org,或者是其它的很多“出名”的网站。

Poincare Conjecture – on contribution

There are so many calculations/divisions/guesses/conjectures on who has made the biggest contribution to solve the problem or how much value the Chinese mathematicians has contributed to the final solution, after the news Chinese mathematicians put final pieces in global puzzle – Poincare conjecture came out.

This is a metaphor. Funny.

A Stage Play of the P Conjecture: Perelman vs Cao-Zhu-Yau

送交者: qed 2006年6月06日07:14:02 于 [教育与学术]http://www.bbsland.com

Stage 0: Poincare, the prophet, told people that there exists a tunnel which would go from this side of the mountain to the other side of the mountain.

Stage 1: Poincare announced that he found a mistake and that the tunnel he found could not go through the mountain but maintained his belief that there still exists such a tunnel yet to be found. This conjectured tunnel was then named “Tunnel of Poincare”.
