你的批注做得真好,减少了我查阅资料的时间。
以前偶尔也看财经,但不知道胡舒立,呵呵。 胡舒立的成长,好像还是很得益于80年代那是相对自由的新闻环境和去国外深入了解学习的机会。 真希望体制内,能多出一些这样的人。

Really broadband! Next gen internet!
Quotes:
Coming soon: superfast internet - Times Online
- THE internet could soon be made obsolete. The scientists who pioneered it have
now built a lightning-fast replacement capable of downloading entire feature
films within seconds.
- Ian Bird, project leader for Cern’s high-speed computing project, said grid
technology could make the internet so fast that people would stop using
desktop computers to store information and entrust it all to the internet.
“It will lead to what’s known as cloud computing, where people keep all their
information online and access it from anywhere,” he said.
- Although the grid itself is unlikely to be directly available to domestic
internet users, many telecoms providers and businesses are already
introducing its pioneering technologies. One of the most potent is so-called
dynamic switching, which creates a dedicated channel for internet users
trying to download large volumes of data such as films. In theory this would
give a standard desktop computer the ability to download a movie in five
seconds rather than the current three hours or so.
- “Holographic video conferencing is not that far away. Online gaming could
evolve to include many thousands of people, and social networking could
become the main way we communicate.- “Projects like the grid will bring huge changes in business and society as
well as science,”- “It will lead to what’s known as cloud computing, where people keep all their
information online and access it from anywhere,”- “With this kind of computing power, future generations will have
the ability to collaborate and communicate in ways older people like me
cannot even imagine,”- the grid could also provide the kind of power needed to transmit
holographic images; allow instant online gaming with hundreds of thousands
of players; and offer high-definition video telephony for the price of a
local call.
- At speeds about 10,000 times faster than a typical broadband connection,

Hi Andrea,

They were divided into three groups. One did 20 minutes of moderately intense exercise on an exercise bike three times a week for six weeks, the second did similar workouts but at a much more leisurely pace and the third did no exercise.
The low- and moderate-intensity groups had a 20 percent increase in energy levels over the non-exercisers, the researchers reported in the journal Psychotherapy and Psychosomatics.

Nice post!Quotes:
Embedded Systems Design - Embedded.com
- A million lines of code printed out would be 18,000 pages. That's a stack six
feet tall (on typical 20 pound paper). Ironically, the listing weighs in at 180
pounds while the actual operating code is mass-free; it'll live in a fraction of
a gram of silicon. Like DNA, code's human-readable description requires
tremendously more mass than its actual instantiation.- A million lines of code is not ten times more than 100,000. It's well-known that
schedules grow faster than the code. Barry Boehm estimates the exponent is
around 1.35 for embedded software. So the schedule for developing a million
lines of code is 22 times bigger than for 100,000 LOC.See my bookmarks at http://preview.diigo.com/user/joel

Suppose you have a passion for items of a certain type, and you wish to start a recommender system around those items. You want a system like Amazon or Epinions, b.
