The Truth according to Wikipedia

Google or Wikipedia? Those of us who search online
-- and who doesn't? -- are getting referred more
and more to Wikipedia. For the past two years,
this free online "encyclopedia of the people" has
been topping the lists of the world's most popular
websites. But do we really know what we're using?
Backlight plunges into the story behind Wikipedia
and explores the wonderful world of Web 2.0. Is it
a revolution, or pure hype?
Director IJsbrand van Veelen goes looking for the
truth behind Wikipedia. Only five people are
employed by the company, and all its activities
are financed by donations and subsidies. The
online encyclopedia that everyone can contribute
to and revise is now even bigger than the
illustrious Encyclopedia Britannica.
Does this spell the end for traditional
institutions of knowledge such as Britannica? And
should we applaud this development as progress or
mourn it as a loss? How reliable is Wikipedia? Do
"the people" really hold the lease on wisdom? And
since when do we believe that information should
be free for all?
In this film, "Wikipedians," the folks who spend
their days writing and editing articles, explain
how the online encyclopedia works. In addition,
the parties involved discuss Wikipedia's ethics
and quality of content. It quickly becomes clear
that there are camps of both believers and
critics.
Wiki's Truth introduces us to the main players in
the debate: Jimmy Wales (founder and head
Wikipedian), Larry Sanger (co-founder of
Wikipedia, now head of Wiki spin-off Citizendium),
Andrew Keen (author of The Cult of the Amateur:
How Today's Internet Is Killing Our Culture and
Assaulting Our Economy), Phoebe Ayers (a
Wikipedian in California), Ndesanjo Macha (Swahili
Wikipedia, digital activist), Tim O'Reilly (CEO of
O'Reilly Media, the "inventor" of Web 2.0),
Charles Leadbeater (philosopher and author of We
Think, about crowdsourcing), and Robert McHenry
(former editor-in-chief of Encyclopedia
Britannica). Opening is a video by Chris Pirillo.
The questions surrounding Wikipedia lead to a
bigger discussion of Web 2.0, a phenomenon in
which the user determines the content. Examples
include YouTube, MySpace, Facebook, and Wikipedia.
These sites would appear to provide new freedom
and opportunities for undiscovered talent and
unheard voices, but just where does the boundary
lie between expert and amateur? Who will survive
according to the laws of this new "digital
Darwinism"? Are equality and truth really
reconcilable ideals? And most importantly, has the
Internet brought us wisdom and truth, or is it
high time for a cultural counterrevolution?

Brion Vibber
Brion Vibber has worked on MediaWiki and
Wikipedia's servers for four years, watching over
its frightening growth from thousands to millions
of pages, from dozens to thousands of hits per
second.
ABSTRACT
Over four years, MediaWiki has evolved from a
quick hack to run a little-known encyclopedia web
site to the monster engine behind a heavily-used
public site, while maintaining the simplicity
needed for an entry-level intranet wiki. Brion
reviews past and future directions for Wikipedia's
software and hardware, and how modern buzzword
technologies could power and simplify the wiki
world.

Google Tech Talks
June 14, 2008
ABSTRACT
IGlobal online services at Amazon, eBay, Myspace,
YouTube, or Google serve millions of customers
with tens of thousands of servers located
throughout the world. At this scale, components
fail continuously and it is difficult to maintain
a consistent state while hiding failures from the
application. Peer-to-peer protocols provide
availability by replicating services among peers,
but they are mostly limited to
write-once/read-many data sharing. To extend them
beyond the typical file sharing, the support of
fast transactions on distributed hash tables
(DHTs) is an important yet missing feature.
We will present a distributed key/value store
based on a DHT that supports consistent writes.
Our system comprises three layers:
- a DHT layer for scalable, reliable access to
replicated data,
- a transaction layer to ensure data consistency
in the face of concurrent write operations,
- an application layer with an extremely high
access rate.
For the application layer, we selected a
distributed, scalable Wiki with full transaction
support. We will show that our Wiki outperforms
the public Wikipedia in terms of served page
requests per second and
we will discuss how the development of the
distributed code benefited from the use of Erlang.
This is joint work of Zuse Institute Berlin and
onScale solutions GmbH.
Speaker: Thorsten Schuett, Zuse Institute Berlin
Thorsten Schütt is a senior researcher with the
Zuse Institute Berlin (ZIB) and a co-founder of
onScale solutions GmbH. He received a CS diploma
with distinction in 2002 from the Technical
University Berlin. Since then he works as a
research staff member in the Computer Science
Research Department at ZIB and participates in
several EU projects like GridLab, XtreemOS and
Selfman. He is the principal system architect of
the scalable, transactional key/value store at
ZIB. His research interests include distributed
data management, scalable grid systems, p2p
algorithms and self-managing transactional
storage systems.

Keith on Wikipedia
DISCLAIMER: I disable comments for two reasons:
1) I think the video speaks for itself,
2) I do not see the value in someone commenting,
"Keith rulz! and I agree with everything he says",
and another person commenting "Olbermann the dork
needs to take his Groucho Marx eyebrows and leave
on a LONG vacation. He is the most pathetic figure
on television. Oh...sorry Rosie...the second most
pathetic figure".
YouTube does doesn't give enough space (500
characters) for intelligent comments or thoughtful
dialogue.
I believe that we're in this mess because people
think that by posting a comment on the internet
somewhere, they're civic-minded and making a
difference when, in fact, the only thing that
makes a difference is commenting where people with
power will hear you and fear your removing them
from power: Through phone calls and snail mail to
your elected officials and marching in the
streets.

| Wikipedia/Discovery: CHINA will replace U.S.A become the World's next Superpower Before 2030 ! |
 |
秦(Qin / Chin)-China 中國(Zhōngguó)-Central
Nation.
Wikipedia: If the economy continues moving at the
same rate,China should overtake Japan as second in
2011 and should replace the U.S.A as the world's
largest economy & superpower on earth in
2030,meaning that the U.S.A will have been the
world's superpower for [90years].Great Britain was
the world's biggest economy & superpower,they
replaced China from Mar1736 till Nov1940
[204years]. China & India was the world's richest
nation & superpower from 2500BC till March1736.
The next superpower:
Wikipedia:The People's Republic of China receives
almost continual coverage in the popular press of
its potential superpower status,and has been
identified as a rising or emerging economic and
military superpower by academics and other
experts.Professor Shujie Yao of Nottingham
University has said "China will overtake the
United States to become the world's largest
economy by 2030 if current growth rates continue",
and that China's GDP will overtake that of Japan
by 2011, and Germany's by 2008. Professor Yao
thinks that "under an optimistic scenario", "China
could become a real superpower in little more than
20 years.
維基百科:
中國被認為是一個潛在的超級大國.
氣候 -
中國大部分地區都處於溫帶氣候，是
有最多溫帶地區的國家。根據傑佛里
薩克斯 （Jeffrey
Sachs）的報告，處於溫帶地區的國家有
著較高的糧食產量，而且比處於熱帶
區的國
家有著更低的疾病爆發機率，尤其是
由飲水與食物傳染的地方性疾病。藉
來自多餘勞動
力所產生的創造力，地理上的優勢對
個國家的長期經濟表現可以造成很大
影響。薩克斯
認為溫帶氣候使這些地區大多是高收
國家，而中國、俄羅斯與東歐各國之
以維持在中收
入的水準，是因為這些國家過去實行
會主義[8]。溫帶氣候對於經濟發展的
益，最早
是由亞當·斯密所提出，較晚則出現在
大衛·藍迪斯（David
Landes）所寫的《國家富窮論》（The
Wealth and Poverty of Nations）中。
中國GDP -
25年來，中國GDP指數都已每年至少10%的
速度增長，是歷史上增長速度最快的
濟實
體。在2005年，如果用市場交換額來說
中國已成為全球第4大經濟體，如以
費量來
說，中國已經成為全球第2大經濟體。2
006年中國GDP指數為8.8萬億美元。同時
，中國政府使3億人口脫離貧困，而且
中國人均收入增長了8倍。
城市 -
中國有很多大城市，中國有170個城市
人口超過100萬。大多數這樣的城市都
高速
公路。這些大城市都是國家或地區的
業，經濟和文化中心。中華人民共和
首都是北京。
上海是中國最大的城市，同時也是亞
地區一個重要的經濟中心，上海還擁
著世界最繁忙 的港口。
貿易 -
在過去4年，中國國際貿易以每年29.5%
速度增長。在2005年，中國出口總量占
世界的7.3%，進口總量占世界的6.3%。中
國目前是世界上第2大貿易國（居美國
）。中國政府大力推動出口醫療器械
和軟件產品。中國的外匯儲備在2007年1
2
月年為1.5萬億美元，成為世界上最大
外匯儲備國。
科技
中國是世界第二大科技研究國，花在
技上的開支僅次於美國，即上年的開
增加20%後
，今年中國在科技方面的開支預期將
有1360億美元。中國現今大約有926000位
研究家。自1998中國政府在科技研究方
所花的錢翻了三倍。在2008年中國的
程博士數量會超過美國。許多外國公
都在中國建立了研究中心。
太空科技 -
在1970年中華人民共和國首次發射衛星
方紅進入太空，成為第五個有能力發
射衛星的
國家。2003年，中華人民共和國成為了
界上第三個可以獨立將人類送入太空
的國家。
2007年，中國成為了世界第三個有能力
導彈摧毀人造衛星的國家。嫦娥一號
繞月衛星
的成功發射標志著中國已經成為了月
俱樂部的一員，中國政府更計劃在2020
年左右向
太空發射一個空間站和執行一個登月
劃。
