- 《新科学家》报道，达尔文的理论也许只是地球演化史的一部分，伊利诺伊大学的微生物学家Carl Woese和物理学家Nigel Goldenfeld相信进化论只是历史上的一个阶段，且是离我们最近的一个阶段。
支持该理论的最新的压倒性证据是“水平基因转移”——有机物从周围的其它有机物“水平”获得遗传物质。提供遗传物质的并不一定是相同种类。这一机制在微生物基因组的演化史上扮演着重要的角色。Woese和Goldenfeld指出，水平基因转移的结果是深远的，它改变了演化进程。在生命存在的数十亿年时间内，微生物代表着地球上的绝大多数生命，因此最古老和最普遍演化形式也许根本不是达尔文理论。

11.6线程----BlockingQueue - 八荒六合唯我独尊 - CSDN博客
/**
使用BlockingQueue的关键技术点如下:
1.BlockingQueue定义的常用方法如下:
1)add(anObject):把anObject加到BlockingQueue里,即如果BlockingQueue可以容纳,则返回true,否则招聘异常
2)offer(anObject):表示如果可能的话,将anObject加到BlockingQueue里,即如果BlockingQueue可以容纳,则返回true,否则返回false.
3)put(anObject):把anObject加到BlockingQueue里,如果BlockQueue没有空间,则调用此方法的线程被阻断直到BlockingQueue里面有空间再继续.
4)poll(time):取走BlockingQueue里排在首位的对象,若不能立即取出,则可以等time参数规定的时间,取不到时返回null
5)take():取走BlockingQueue里排在首位的对象,若BlockingQueue为空,阻断进入等待状态直到Blocking有新的对象被加入为止
2.BlockingQueue有四个具体的实现类,根据不同需求,选择不同的实现类
1)ArrayBlockingQueue:规定大小的BlockingQueue,其构造函数必须带一个int参数来指明其大小.其所含的对象是以FIFO(先入先出)顺序排序的.
2)LinkedBlockingQueue:大小不定的BlockingQueue,若其构造函数带一个规定大小的参数,生成的BlockingQueue有大小限制,若不带大小参数,所生成的BlockingQueue的大小由Integer.MAX_VALUE来决定.其所含的对象是以FIFO(先入先出)顺序排序的
3)PriorityBlockingQueue:类似于LinkedBlockQueue,但其所含对象的排序不是FIFO,而是依据对象的自然排序顺序或者是构造函数的Comparator决定的顺序.
4)SynchronousQueue:特殊的BlockingQueue,对其的操作必须是放和取交替完成的.
3.LinkedBlockingQueue和ArrayBlockingQueue比较起来,它们背后所用的数据结构不一样,导致LinkedBlockingQueue的数据吞吐量要大于ArrayBlockingQueue,但在线程数量很大时其性能的可预见性低于ArrayBlockingQueue.

Verbraucher wollen Strom lieber selbst produzieren
84 Prozent der Verbraucher in Deutschland sprechen sich für die Erweiterung der dezentralen Energieerzeugung aus. Dass möglichst viele Haushalte selbst Strom produzieren sollten, etwa über Solaranlagen, hält eine große Mehrheit für wichtig. Jeder vierte Immobilienbesitzer will in den kommenden fünf Jahren Solarzellen auf dem Dach installieren.

Language has developed chronologically, growing at par with the society. This is not true anymore; Internet phenomenon has made our society too large too soon. Single culture does not drive language growth anymore; arrogance, ignorance and market forces are manipulating it to the level of mutation.

Using Enterprise 2.0 to prepare for recovery (part II) - Whitepaper to download
In a business world where change is constant, knowledge becomes an essential asset for any organization. Survival and growth require the development of solutions that will optimize collaboration and knowledge management.\n\nFocussing on this topic we recently produced our first whitepaper. It analyses the benefits associated with the introduction of Enterprise 2.0 solutions, and positions the collaborative management of knowledge as a stable and lasting solution, especially in these times of economic tumult.

L'Entreprise 2.0 pour préparer la reprise (part II) – Whitepaper à télécharger
Dans un monde des affaires en perpétuelle mutation, la connaissance devient un capital essentiel pour toute organisation. Leur survie et croissance passe par la mise en place de solutions optimisant la collaboration et la gestion des connaissances.
Forts de ce constat, nous avons récemment travaillé à l'écriture de notre premier livre blanc (disponible en anglais uniquement). Il se veut être une analyse des avantages liés à l'introduction d'outils de l'Entreprise 2.0, et positionne la gestion collaborative des connaissances comme une solution stable et durable, plus particulièrement en ces périodes de tumulte économique.- - By Gregory Culpin

The Augmented Social Network - building identity and trust into the next-generation Internet
Could the next generation of online communications strengthen civil society by better connecting people to others with whom they share affinities, so they can more effectively exchange information and self-organize? Could such a system help to revitalize democracy in the 21st century? When networked personal computing was first developed, engineers concentrated on extending creativity among individuals and enhancing collaboration between a few. They did not much consider what social interaction among millions of Internet users would actually entail. It was thought that the Net's technical architecture need not address the issues of "personal identity" and "trust," since those matters tended to take care of themselves.\n\nThis paper proposes the creation of an Augmented Social Network (ASN) that would build identity and trust into the architecture of the Internet, in the public interest, in order to facilitate introductions between people who share affinities or complementary capabilities across social networks. The ASN has three main objectives: 1) To create an Internet-wide system that enables more efficient and effective knowledge sharing between people across institutional, geographic, and social boundaries. 2) To establish a form of persistent online identity that supports the public commons and the values of civil society. 3) To enhance the ability of citizens to form relationships and self-organize around shared interests in communities of practice in order to better engage in the process of democratic governance. In effect, the ASN proposes a form of "online citizenship" for the Information Age.

Hub / Hub Culture News / News / Thoughts on the Emerging Collaboration Economy
"Hub Culture founder Stan Stalnaker shares his thoughts in a Q&A with Rachel Botsman on sharing, the power of the commons, and peer-to-peer transaction.
Rachel Botsman is co-authoring a book with Roo Rogers entitled What’s Mine is Yours: The Rise of Collaborative Consumption (being published by Harper Collins in 2010).
The book is about how people are collaborating together through organized sharing, bartering, trading, renting, swapping and collectives to get the same pleasures of ownership with reduced personal cost and burden -- and lower environmental impact.
RB: We look at how look how social networks and web technologies are giving new relevance to pre-industrial behaviors such as bartering, swapping, trading, social lending etc. that require marketplace structures. Essentially how we are going back to ‘human to human transactions’ between producer and consumer, seller and buyer, borrower and lender, neighbor to neighbor etc. What are your thoughts on this? What are your favorite examples of this in action?
SS: We see the world evolving into a complete peer-to-peer system, beyond just communications but in finance and eventually energy as well. This means that the ability for individuals to transact with each other, at the mass-micro level, will transform how we value our sense of worth and of selves. The explosion in virtual and digital communities is driving this, and layered over existing 'real-world' relationships, creates a transactional fabric that will soon dominate the economic system.
In the end, I think we will see an emergence of an economic relationship and fascination with networked efficiency that comes to dominate our worldview. This fits well with the sustainability model we need to develop to dovetail resource availability with demand; and not a moment too soon."- - By Wildcat2030 wildcat
The Earth Citizen Movement | BrainWorld
"If someone asks you who you are, how do you identify yourself? You may tell them your name, job, nationality, race or religion. You probably realize that this answer does not encompass who you truly are. As we classify ourselves in various categories, we establish divisions between ourselves and others. Often it requires a catalyzing event, such as a natural disaster, for people to realize that we cannot survive if we don’t work together.
__ Today, due to global warming and other environmental issues, Earth faces many such disasters. Ilchi Lee, founder of the Earth Citizen Movement, first issued a call to action in 2001 in his book Healing Society. He wrote that once 100 million people realize they are Earth citizens and take action together, they will change the world. Enlightenment, Lee states, is not just knowledge. It is also action. Without action, he claims, knowledge is useless.
__ The purpose of Lee’s Earth Citizen Movement is to get people to declare themselves citizens of Earth. Rather than identifying with their nationality, race, or religion, they accept that they are human first, living together on Earth. The members believe human beings are all connected, and that realizing our common values will be the first step in recovering our humanity.
__ The Earth Citizen Movement formally began in April 2009 and is growing all over the world. It has members in the United States, Canada, United Kingdom, Germany, Sweden, Russia, Korea and Japan. So far, over 100,000 people have joined. The movement’s goal is reach to 100 million people.
