Windows server exposed high-risk vulnerability

Windows server has been blasting the high-risk remote code execution vulnerability - MS12-020 Microsoft of the vulnerability level is set at the highest level - severe (Critical), the attacker can send a particular packet to the remote desktop port (port 3389)access to administrator privileges.

History on the same level of vulnerability caused tremendous damage and loss. In 2004, MS04-011 vulnerability to cause the attacker remote 445 port to send a particular packet, and execute permissions and dissemination of virus. Rely on the dissemination of this vulnerability Sasser virus to cause paralysis of the global large number of computers. In 2002, the Windows RPC vulnerability that the attacker remote control server through port 135. Lead to large numbers of computers around the world rely on the propagation of shock waves of this vulnerability virus automatic shutdown cheap cell phone cases .

Windows RDP service vulnerability allows an attacker to control user server or cause a blue screen, once widely used, not only will the impact of the normal application of this server is running, but also make the server exclusively as a tool for hackers to control the use of, the entire Internet is causing greater harm cellphone accessories wholesale .

Microsoft said most customers to enable the automatic updates, they do not have to take any action. But many of the Windows server is not turned on in the course of "Automatic Updates" security Po, suggesting that the server administrator immediately download and install the official patch, to avoid the losses suffered due to the vulnerability. At the same time, the majority of the server administrator can detect the server whether there is the risk of this vulnerability.

Security Po pointed out that there are loopholes in the file is rdpwd.sys loopholes is HandleAttachUserReq () function. If an attacker sent to the affected system a series of specially designed the RDP (Remote Desktop the Protocol Remote Desktop Protocol) packets, this vulnerability could allow remote code execution cellphone cases wholesale .

Facebook follow Apple: reliance on external developers to reduce development costs

Facebook last year's R & D expenses in total income accounted for only 10%, lower than the Internet companies such as Zynga and LinkedIn recently listed. This seems to follow the example of Apple's approach: to lower the costs, and with external developers to expand the R & D.

Lucrative

As the world's largest social network, Facebook has been the hacker culture is known, and often held a number of programming. But the company is now increasingly encouraging external developers to add functionality for their website cell phone case wholesale .

Facebook will be the IPO (initial public offering). U.S. investment firm BGC Partners analyst Colin Gillis, Colin Gillis, due to lower research and development costs, making Facebook more profitable than the other upcoming IPO enterprises. But the company's challenge is how to deal with the challenge of Google and young start-up companies, in order to maintain the growth rate.

"They have a huge profit when a company is listed, investors usually want to see margin improvement." Gillies said. Facebook's 2011 profit margin of 27%, higher than 19% in 2010 and 2009, 16%, also higher than the S & P 500 index, the average profit margin of 14% cellphone cases wholesale .

Facebook is currently emulate Apple's business model, the latter is the largest enterprise in the global market. While Apple is independently developed a lot of technology, but to attract outside developers and has developed hundreds of applications for the iPhone and iPad. In this way, there is no need to spend too much R & D costs, and still be able to enhance customer loyalty. Apple on a quarter of R & D expenses in total revenue accounted for 1.6%.

"Apple has not any R & D costs of the application developers through their own earnings, but we see the benefits of this innovation. Facebook, the same is true." Dartmouth Business School professor Ron Adelaide satisfied, Ron Adner said.

In the case of Facebook, Zynga, and other developers to play an important role. Zynga Facebook offers a variety of the most popular games, including "FarmVille", "Mafia Wars" and "Words - With Friends".

What will Humans evolve into?

"About 700 years later, too lazy, people on earth generally fat, feet due to degradation has been unable to walk upright, everyone is like a bubble in the air, only mobile floating chair sitting, like the stalls in the chair a pile of flesh ... "This is a 2008 swept the world of American science fiction animated" Robot Story "scene depicted on the future of humanity, although there are some jokes and banter, but the film also revealed concerns about the future of humanity degraded.

Recently, some of the information from scientific research institutions show: humans are getting shorter, fat, and its skull capacity showing a downward trend, so some people began to worry about: grow shorter ugly stupid in the future will become humans can not escape the fate?

Natural selection has never been human failure

Many biologists believe With the continuous development of human society advanced medical technology and the improvement of social welfare measures, mankind no longer need for survival, struggling, cell phone case wholesale natural selection of evolutionary theory are no longer applicable, the human is no longer evolution.

But there are a lot of anthropological researchers oppose this view. Throughout the biosphere, natural selection has always been the objective existence of the human into the civilized society is still no exception, no matter how human technology and culture development, they always play a leading role in the chain of human evolution, can not eliminate the role of natural selection in the face of technology and culture, human natural selection process will be subject to some interference, but this is still the selection mechanism will quietly play a role in the Institute of Vertebrate Paleontology and Paleoanthropology, Research Associate, Lee Chun-cheap cell phone cases  .

In recent years, some foreign researchers through the sample study found that the human is still evolving scientific and technological progress and cultural progress is still not rid humanity of the law of "natural selection" in complying with the laws of nature.

October 7, University of Montreal, Quebec, Canada Branch researchers said they Aoku De Island, 80 kilometers northeast of Quebec City, Canada, found evidence of human evolution.

Aoku De Island residents and ethnic structure of a single, similar levels of education, believe in the same kind of religion, is an ideal sample of the data analysis. Researchers access to registration records of the local church from 1799 to 1940, found that in 140 years, women's first child, aged about 26 years old to 22 years of age.

The exclusion of social and environmental impact factors, the researchers found, their first child early women by nature favor. Other sample studies have reached the same conclusion.

In addition, in the second half of 2009, the evolutionary biologist Professor Stephen Stearns of Yale University and his research team are also the U.S. National Academy of Sciences published studies have reported that through research, they found that body weight, height genetic characteristics still influence the number of children of women and children's health.

The researchers found: Compared with lean women with higher partial short little fat of female children born; fertility earlier, stop by the late, as well as blood pressure and cholesterol levels lower than women usually have a family. In addition, the characteristics of these favorable human reproduction will be transmitted to the daughter of these women, the daughters tend to have more children.

Obviously, natural selection is still quietly play a role

You know about hypnosis?

Believe that people for "Internet addiction" is a morbid, or non-substance dependence can become an independent diagnostic classification has been debated, but a large number of young people due to over-indulge in the Internet, cellphone cases wholesale which led to significant social,psychological problems or brain dysfunction has long been an indisputable fact.

Unable to establish the animal to the Internet model, the medical profession can not be the way of animal experiments addiction led to the change in the evidence of brain function, but only to rely more on access to relevant clinical data.

At home and abroad in recent years a large number of research suggests that substance addiction internet addiction and drug abuse have similar behavioral characteristics and physiological changes, for example,cellphone cases wholesale  both the compulsion for specific things (addictive substances or the Internet) , which are related to the activity of the mesolimbic dopamine reward system.

Dopamine is secreted by nerve endings act as a messenger of a specific chemical substances, and its people's cognitive, emotional and behavioral problems have a very important role in regulating .
