SONY's SONY online entertainment

CNET science and technology on May 3rd international news: SONY's SONY online entertainment department (hereinafter referred to as "SOE") announced on Monday, because in the security attacks last month during the investigation found that the new problems, this company has been closed for the PC online gaming service.

SOE a spokesman says, PC online gaming service closing time is the Pacific time Monday morning, but no disclosure 1:30 affected users quantity. Except on the website published a short news outside, SOE didn't notify users in other ways.

The spokesman said games online services, shut off the PC is not happening, "" second attack with SONY PlayStation network and relevant," we attacked in survey found a we think are serious problems, therefore decided to temporarily closed PC online gaming service ".

Less than a week ago, SONY warning users said the SONY PlayStation network hackers, stolen 77 million account name, address, password and data such as credit card Numbers. SONY found safety after a week to attack only user alert.

SONY PlayStation network executives on Sunday SONY to hacker attacks, and said it will apologize users gradually restored services, to users provide free part content.
CNET science and technology on May 6, Beijing (article/wood sen) : the day before China appeared first login nyse social web site -- everybody nets, the website of the predecessor is in 2006 is the campus network and sponsored acquisition under the integration of 5Q sponsored campus life, this is a complex body, is the former CEO website with a social networking site for 11 years experience, and now started the XuChaoJun light blog little nets.

Zhongguancun at two o 'clock in the afternoon, the hand of him ipad2 and iphone4 punctual appearance in the cafe, looking at opposite agreed in a yellow T-shirt and blue jeans and a face of XuChaoJun smile, it is hard to imagine he is experiencing the undertaking difficulty.

"I like to run in the west, often run on the playground of tsinghua 5000 metres or 10,000 meters, the most enjoy the moment run!" Such hobby that embodies the character is just XuChaoJun finally choose their own business for the best explanation.

Financing is crazy adored

May Day ago, XuChaoJun announced before the nets in dots not open beta already completed A $10 million or more rounds of financing, the Internet social industry for large investments by lianchuang source,mbt shoes usa sequoia capital and innovation workshops completed.


Material graph: little nets founder and CEO XuChaoJun

It was the current Internet enterprise financing are simple, rather XuChaoJun and his product little nets.

"This year on March 1, I give VC friend text messaging to financing thing, inform the results have 7, 8 home VC scramble to investment." In XuChaoJun tone, seems to have absolutely no accident. This outcome knew

"March 2, we determined the curator of sequoia capital and the two tapping innovativeair-powered source cast institutions, many VC chooses waiting for our second round of financing." XuChaoJun said.

Face to face with the "copy door"

In fact, so far, little nets haven't profit model, only in America, MBT Shuguli this website is currently pioneer global ranking 45, fast development situation, XuChaoJun is not afraid to say little nets copy this website, "baidu learning Google, tencent learning ICQ, optimal cool learning Youtube Twitter, sina micro bo learning, they succeeded, we learn, is the process of immediately will start localization."

One senior Internet personage thinks, American Internet industry walk in front row, in global search engine or domestic, regardless of e-commerce in the United States, or to MSN can find model, little nets unavoidably fall into such misconduct, and can do the most important to success.

From XuChaoJun planning description can see little nets future rudiment, "former social networking sites are enlightening stage, the real Web2.0 the power make up is maintained than encyclopedia britannica also professional content, little nets is to make it gathered in the first place." our wisdom

"If the micro bo focus on social events of words, we focus more on interest, the future of the media will more and more professional socialization." In XuChaoJun opinion, micro Po and little nets can coexist, "as the United States' know the 'and' facebook, they are as" coexist newspapers and magazines relationship."

Venture is like driving

Any a startup roads are not so is flat, little nets.

In "copy door" just passed, ushered in "push him" big MBT Fanaka challenge for today and the future may meet competition, XuChaoJun look more embodies these four words poised.

"Business is like driving is same, who all didn't know what to expect, all I can do is to grasp the good direction, to prepare food, bring the strength of funds at the destination forward." team

In the last two hours of interviews, XuChaoJun maintained a confident smile, but this does not mean that no pressure, "every venture companies have mission, let China Web2.0 successful mus!"

Just established three months of little nets registered users, has exceeded 15 million XuChaoJun laughed and said: "only reached 10 million, I will dare to sleep." Realizing this number, believe not long!

silicon replaced by silica vertical fins stretch.

Intel called 3D transistors, but technically speaking,mbt shoes usa this is three transistors. The traditional 2-d door by thinner 3d silicon fins, silicon replaced by silica vertical fins stretch.

What is silicon fins?

The door wrapped silicon fins. Silicon fins on three sides by the parcel control, top parcel a door, side of each package a door, three doors. Package 2D two-dimensional transistor only top a door parcel control. Intel this explanation is simple and stark: "control gate increase in 'open', the transistor, the current state of as much as possible through will; and in the state," shut 'to zero, as current will be minimal energy consumption in two states. Transistor to switch between to significantly improve performance quickly."




Its importance?

To confirm Moore's law is very important. Every two years, according to Moore's law, the number of transistors on a silicon wafer equipment double. With shrinking the size of the equipment, according to traditional 2-d way of adding transistors number is unlikely. Therefore, 3D or vertical transistor is very necessary. Intel is not only theoretically proved its feasibility, is also making the chips based on 3D transistors.



Intel distance with this technique how far?

Essentially, Intel is a manufacturer. Therefore, when the company announced a new technology, absolutely not an air-castle originality. Intel's next generation processor that Ivy Bridge will be using this 3D transistor technology sole. That is to say, Intel in production that Ivy Bridge chip will exit 2D transistors manufacturing business, fully turn to 3D transistors. The end of this year, that Ivy Bridge will enter commercial production, 2012 into mass production.

The important significance of 22 nano is what?

That Ivy Bridge will use 22 nanotechnology, the current Sandy Bridge processor USES is 32 nanotechnology. In addition to the above, using the 3D transistor results can improve the geometry usually smaller faster processors and energy efficiency.

3D transistor means products faster?

Of course, 3D transistor means not only chip faster, MBT Fanaka and also means more energy-efficient. Intel's biggest challenge is not speed, but energy efficiency. 3D transistor can make chip in low voltage, leak less environment operation, the Intel chip performance than previously higher, energy efficiency is better.



3D transistor technology help Intel in the smartphone and tablet computer field effective competition?

Theoretically possible. ARM company is currently Intel's new main competitor.MBT Shuguli ARM chips used in global most tablet computer and smart phones, the main reason is its energy-efficiency high. Intel 22 nano 3D transistor technology performance is 32nm two-dimensional transistor improve 37%. Intel said: "that means 3D transistor applicable to small size handheld devices, repeatedly switch energy consumed. The same performance with low energy shortage, 3D transistor 32nm two-dimensional transistor half."

the fundamental transformation planar transistor structures

CNET science and technology on May 6 commentary from LiuKeLi) (article/more than 50 years ago silicon transistors, semiconductor integrated circuit invented since, 3-d structure in batch production, first transistor is this 2011 Intel May 4, 2008 at headquarters is located in Santa Clara, California announced today the significant breakthrough. This marked the future of 3D technology, using CPU power consumption will reduce half. Called three screens Gate) Tri - (revolutionary 3-d transistors design (Intel was first reported in 2002), and in batch production by the end of the Bridge r&d code that Ivy 22 nano Intel chip.
Actually, Intel CEO in 2003 to visit China Barrett in answer reporters about Moore's law without considering the growth of power consumption, is revealed about 3 dimension door technology development situation, in 2008 reporters to the headquarters have interview also ask related progresses Barrett, get a "3-5 years to realize", released today after eight years of the paragraph 3 - D three grid transistor from 2 - D represents the fundamental transformation planar transistor structures.

Using the current transistor all semiconductor integrated circuit are 2D, namely semiconductor crystals just born in plane inside, and 3D transistor grows in three dimensions, not only, and can reduce integration improve more than 50% of the leakage current, so that, in theory all semiconductor chip can reduce half the power consumption in the future.

Intel and CEO for Mr Otellini (Otellini) said: "Intel's scientists and engineers by using 3-d structure, and once again, the transistor revolution realize the Moore's law. As we push into new areas, 3-d structure will help us make astounding and can change the world equipment."

And the 32nm plane transistor before, compared to 3-d three 22 nano in lower voltage grid transistor performance improves 37% and requires consumption less than half the power, can achieve and the 32nm chip 2-d planar transistor the same performance.

Transistor ten milestone

1, 1947, December 16 WilliamShockley, John Bardeen, Walter Brattain and uncovered at bell LABS successfully developed a transistor.

2, 1950: William Shockley developed bipolar junction of transistor, mbt shoes usa is now popular standard transistor.

In October 3.1954 first 18: TR1 transistor radios Regency listed, this kind of radio inside contain only four germanium transistors.

3, 1961 April 25: Robert Noyes get first integrated circuit patent. First transistor radio and telephone speaking about is enough, but newer electronic equipment specification more small transistors - integrated circuit.

4, 1965: Moore's law was born - Gordon Moore in the electronic magazine article published prediction: the number of transistors on a chip future doubling approximately every year for 10 years, fixed (doubling every two years. Three years later, Moore and Noyes created Intel, English name is "the Intel integrated electronic (abbreviation of done electronics)".

5, 1969: Intel uncovered a successful development of silicon transistor technology grid fact. These transistors continue to use traditional silica (SiO2) gate medium, but introduced a new poly gate electrode.

6, 1971: Intel introduced the first microprocessor - 4004. 4004 specifications for 1/8 "x 1/16 inches, including 2,250 a transistor, using Intel 10 micron PMOS technology in 2 inches wafer production.

7, 1985: Intel 386 microprocessor containing 275,000 had a transistor, published 4004 transistors, is the number of initial more than 100 times. 386 32 bits chip, has many tasks to handle ability, can also run multiple programs.MBT Shuguli First is the use of 1.5 microns CMOS technology manufacturing.

8, 2002 August 13: Intel released 90 nanometres processing techniques, including some technological breakthrough high performance, low power consumption, high silicon transistor, the strain copper fittings and new low - k medium materials. This is the first time in production process using strain silicon.

9, in September 2007: Intel announced the transistor materials using breakthrough - high - k metal grid. Intel will use these materials in next generation processor, Intel company KuRui 2 dual-core, Intel KuRui 2 four processors and Intel hypercore processor to strong series of hundreds of millions of 45 nanometer transistor used to construct insulation "wall" and switch "door", r&d, code-named Penryn.

10, 2011 May 3 - Intel announced batch production of a kind of brand-new transistor design. Three screens in various computing devices transistor (from server to in desktops, from a laptop to a handheld device) to implement the performance and unprecedented energy efficiency.

Background:
22 nano exactly how to small and strong

The earliest in 1947 by bell LABS is very large, the development of transistors that usable hand assembled directly. The contrast with the needle on is, a can accommodate more than 1 million 22 nano three grid transistors.MBT Fanaka This paper an English festival symbols more than 600 million on can accommodate three grid transistors. 22 nano

22 nano three grid transistor gate is very small, a human hair width can accommodate more than 4000 grid. GuoGuo one common in accordance with the development of transistor speed house sustained narrow, it has little to you only through a microscope to see it. Want to see with the naked eye 22 nanometres transistors, you must put a chip amplification is greater than the house. In 1971 with Intel microprocessor 4004 launched first, compared the running speed of 22 nano CPU increased more than 4,000 times the energy consumption, and each transistor reduced the 5,000 times. The price of each transistor reduced to the original 1/50000.

A 22 nano transistor can be in 1 seconds switch 1000 million times. One switch so many times lights, almost needs spend 2000 years.

It is one thing to design three grid transistors in batch production, is another. Intel's factories producing more than 50 million every second, every year 150,000,000,000,000,000 a transistor is. This equates to all the world men, women and children have more than 2000 million transistors.
