Popularity of wordpress manifested by the existence of wpchina

As a wordpress newbie of less than a month, I ran into this pretty chrome app called JustWriteBlog by a Chinese developer.  Beside noticing this versatile developer named shinemoon after some digging, I got to know that there is a Chinese unofficial website for wordpress called wpchina.org.  Unlike the relation of renren to facebook, wpchina is a site maintained by a community of Chinese users providing mainly wordpress concept and software in the language of Chinese, while respecting the origin of everything, wp, in its domain name.   Apart from bridging the language gap between an enormous Chinese-only user and the world, I cannot help suspecting that the great fire wall is blocking wordpress, at least once in a while.  Although it turned out that it is not blocked according to this list on Wikipedia as of 4/27/2011, there is really no guarantee that wp access in China can stand forever, especially when the Chinese user population grows.  Text posts on wp are still less influential than video or photo blogs that sinisterly indicate something while not explicitly write it out.  With all these reasons, wpchina arises and seems to be getting vivid.
The greatest wall of China is language and culture, which is also the most precious legacy of China.  Is there really a way to balance preservation and development?

今何在与江南的爱情观

没搜到关于这个题目的太多信息,有这么一篇:
  我不如你,我是早没有了少女心的了——唔,可能连少年心都已没有。《悟空传》之所以当年能引起那样大的反响,追捧它的也都以学生为主力军,很大的原因是因为,它符合少年们钟情于毁天灭地的热血心情。
今何在的青春期延续时间比一般人都长,到二十多岁时还能那样激情洋溢,整篇文真是一鼓作气,当然,这也叫作随想随写。稍许有了点梗概,搁心里就发慌了,得赶紧落到手指上来,不管是动笔还是敲键盘。
我是觉得,他就是写《悟空传》的时候太顺了,导致他写今后每一部的时候都杯具,直接进入挤牙膏阶段,那叫一个辛苦。他写原创不够洋洋洒洒,远不及写同人的时候更有构架感。究其缘由,我想,是由于今何在是个构筑故事剧情走向强过刻画人物性格萌点的写手。也许他确实很能幻想,但他不够现实,(现在这毛病似乎好了一些)笔下的人物都是为了剧情而在动,而不像有些写手,人物性格太过丰满了,连剧情的都只好为他们让路。
最显著一点,今何在不会写女人,甚至于可以说,他对女人的了解真TMD浅薄。在这上头江南也一样。记得群里曾讨论过:江南的套路是,书里永远都有一个娇小玲珑古灵精怪的黄蓉,他就好黄蓉这一口。你让他去写御姐,写女王……好吧,他自己也承认没写出个像样的来了。
今何在同理,没准他比江南还不如,他笔下的女人从来都是为了辅助男人的梦想而存在的,男人要没了,她们的光彩也就消失了。《悟空传》里最明显的是紫霞跟小白龙,一个同生共死了,另一个也同生共死了,死之前还要为了男人犯最后一次天条。她们的存在只是为了在末路英雄孤军奋战到最后一刻,没有其他任何人再站在他们一侧时,她们以血肉之身为代价,只为陪在他们身旁。
RBT,这是一种纯男性思维个人英雄主义的爱情观。

我想找的只是这篇的后两段,总的来说就是这俩人的爱情观虽不同,体现在女性角色的性格和命运上,但是共同的是“对女人的了解真TMD浅薄”。这可能正是我喜欢他们的故事和角色的一个重要原因呢。当然我不同意这篇里说今何在“笔下的女人从来都是为了辅助男人的梦想而存在的”,而江南的女性都是黄蓉,不过如果说他们都没经历过很多女性可能差不太多。这几个女性角色确实单一啦,而且每个故事里也就一两个女的,男的一大堆,是不是说明在他们和我们的青春期世界里,兄弟占很大比重,也更多种多样,而女性只是幻想,于是比较容易把所有幻想都集中在一个女性角色上。

对女人的了解“浅薄”,可能也是他们幸运的地方吧,所以故事才会清新,纯净。你了解了女性越多了解女性,故事中就会越多出现“不知死活”的女人的各种纠结思维,也就没那么畅快的情节了。可是现实就是这样,没法像他们“童话”小说里那么通透。

two hands both grabbing, both hard

Software tool: OMENet++, SUMO
Hardware tool: GNURadio->USRP2

MATLAB just doesn't sound so professional. It can do something pretty fast at the beginning, but limited when you gets deeper. MATLAB is good when the problem is well defined, extracted above real-world mess, in other words, for science. For simulations and experiments, maybe something dirty would be more impressive.

Plone

I just ran into this powerful tool that can generate a webpage as its minimal functionality. The homepage of Radioware@ND, directed by laneman, is generated using this tool. And the tool is opensource. I guess it's worth to learn this toy.

UHD replacing USRPx

Universal hardware driver (UHD) is meant to be a driver that can interface with any devices (USRP1, USRP2, N210 etc.). And in gnuradio-companion, there is a wrapper called UHD with only a source and a sink. There is an option called "Device Addr" in either UHD block, which I thought it would be the ip address of my USRP2. Then it gave me error of "RuntimeError: ValueError: invalid args string: 192.168.10.2". Going through the c++ code for uhd_usrp_sink couldn't help me understand what args string would be valid, but googling for an image of the UHD USRP sink block (http://old.nabble.com/GNURadio--%3E-UHD-transition-LFRX-(Ubuntu,-Karmic)-td30542095.html) indicates that I should have left the blank empty. And it runs happily after.

How weird.

a script to install uhd gnuradio

The address to download most recent images (http://www.ettus.com/downloads/uhd_images/UHD-images-most-recent/) was broken at the time I run it. Changed it to http://www.ettus.com/downloads/uhd_releases/003_000_001/images-only/UHD-images-003.000.001.tar.gz

gnuradio forum

there is a ruby-forum that has a gnuradio mailing list interface, and there is a python-forum without anything to do with gnuradio. however gnuradio is half on python and half on C++.

why is that?

the message of "No USRP2 found" doesn't mean anything

Although I do not know why find_usrps does not find anything, even if I specify the network interface as "-e ethX", usrp2_fft.py runs alright on "-e ethX".

I have gone through almost all the posts returned at the inquiry of "No USRP2 found", "Raw Ethernet", etc. None of them mentioned that IT DOESN'T MATTER...
