The tide information is suspected of being involved in concealing The cloud calculates into a trap
To indulging in the tide information ” The cloud calculates ” Conceptual investors will come to say, two pieces of latest information can’t be ignored: Scheduled to release in the first quarter originally ” Yun Hai ” The operating system V1.0 edition of computing center of cloud, have not released so far; It is estimated that reports the material about issuing additional and is raised and thrown the cloud computational item to the supervision department on about April 10, have not appeared in the newspaper so far.
The tide information is listed on it 0.32 yuan / burst in nearly 11 years so far, only share out bonus, the failure to work of any kind is financed again. This time the company plans to issue additional and raise the money of 1 billion yuan, and the investment orientation is Hi-Tech ” the cloud calculates ” ,Concerned by market extremely naturally. But the reporter finds in the investigation, it is exactly such a listed company shrouded under the Hi-Tech ring of light, not only the related trade reveals unureally, but also conceal the detail of holding shareholder’s stock right property alteration sedulously.
Arise suddenly and advance it slowly again definitely, extremely confused that the company manages, this very difficult to allow people to the tide information one ” The cloud calculates ” Suspect the prospect: Develop but the pie of one on earth? Attempt to enclose the trap of the money?
Reporter Zhu JianPing Editor Qiu Jiang
” calculation of cloud ” Still the cloud hides the fog cover
Investors orient and issue additional 1 billion yuan to cast to the tide information on assumed progress of cloud and pay close attention to very much all the time. On March 23 this year, the company has claimed to report the relevant material at the annual general meeting of share-holders on about April 10. But the reporter knows today, so far, the company has not reported materials to the supervision department.
This seems it is identical to the assumed attitude of cloud at first with the aspect of company upside down. At annual shareholders’ meeting of the tide information of May 19, 2010, the company has shown clearly, “the cloud calculates it is only a concept for company at present, the company has not developed the relevant products, can not bring the real income for a long time. ” So, the company still authorized administration and supervision authorities by not exceeding 150 million cash to buy bank wealth management products at that time, but not is used for putting into the cloud and calculating.
Different from it, but company’s big shareholder’s tide group calculates to the cloud that is ” deeply in love with ” . Reveal according to a research report which hits the gold company: “The tide group has held the achievement of 2009 to review and expect in 2010 the media communicates and knows in Beijing, Yuan YiSheng, Vice President of group, emphasizes at the meeting, the tide will set foot in the cloud to calculate the market formally in 2010, and will be devoted to putting out the independent cloud standard. ” On the local official media of Shandong, the cloud calculates that sees all newspapers frequently too by strategy in the tide group.
Until cloud calculate concept ferment at capital market gradually, tide the intersection of information and stock price hurricane of Luis first rise since October of 2010, the p/e ratio is up to 1104.64 times for a time. By November 1, 2010, the tide information reverses the assumed attitude of cloud dramatically too, to calling in the unusually undulatory verification announcement of the stock price in its one that releases: “Operating system of ones that will put out developing independently before the end of the year in the company ‘ the cloud calculates ‘ “But a odd one is, big shareholder’s tide group reduces the share of 2,792,500 gangs of companies in following 7 trading days.
Can see what the company develops in the expectation of market independently before the end of 2010 ” The cloud calculates ” At the time of the operating system, ” break the promise ” in but the tide information used after a verb to indicate the completion of an action. “In December of 2010, the company will research and develop and finish the Alpha edition of the operating system of computing center of cloud of ‘ a sea of clouds ‘. It is estimated in first quarter of 2011, the company will release the operating system V1.0 edition of computing center of cloud of ‘ a sea of clouds ‘. ”
As to this, software insider shows, a section of software is from testing to putting out formally, generally need to pass Alpha edition, shellfish’s tower edition, BC edition and RTM edition. So-called ” Alpha ” The edition, namely internal test edition, this edition shows this software mainly relies mainly on realizing software function at this stage, usually exchange only in developer’s inside of the software. Generally speaking, software of this edition needs continuing revising, only the tester, otherwise not propose using. Built-in testing common to examine stage, re-adapt, until RTM being the intersection of final standard and edition.
But until today, 2011 already will it be 5 more than month the past in year, tide the intersection of cloud and the intersection of computing center and edition, V1.0 of operating system, of message does not see the trace yet.

Technological revealed secrets of cache of hard disk of Intel Z68 solid condition
Buffer technology as to Smart Response Technology solid condition hard disk that Z68 chip set that Intel will be released soon supports, we have already analyzed in detail a few days before. However, a question that everybody cares about most was not answered yet, that is: What size can Intel, this technology, bring to characteristic of hard disk on earth promotion?
A few days ago, demonstrated within a Intel the slide was exposed in the network, revealed the answer to a riddle of the question at last. According to the official test of Intel, in Core i7-2600K, person’s DDR3-1333 memory once of 2x 2GB money, on Windows 7 64bit SP1 platform, use a piece of western data 1TB SATA 3 solid condition hard disks, and a Intel ” Larsen Creek ” 20GB solid condition hard disk, utilizes the solid condition hard disk of Z68 to buffer technology and construct ” mix the hard disk ” ,PCMark 05 hard disks of scores that can be made systematic are promoted by 355.5%, the toggle speed of the operating system is improved by 19.4%, machine available-time reduces to 28 seconds from 35 seconds.
In fact, this technology of Intel has a long history, can trace back to ” flashing memory slot ” appearing by batch P55 chip set mother board memory slot initially . The technological coaxiality Braidwood at that time, just used flashing memory as the hard disk to buffer, promoted the magnetic disc characteristic.
Acceleration flashing memory slot that appeared on the first batch of P55 mother boards that yearAnd reached this generation, popularize the improvement of the intensity with the hard disk of the solid condition, it was moved towards at last practically that the hard disk of this solid condition buffered technology. Moreover, Intel will take this opportunity to popularize one’s own solid condition hard disk products too. For example ” Larsen Creek ” appearing in the official side tests The low-end solid condition hard disk that Intel will be released soon, is called series 311, the leading ultra low price, the price may be less than 50 euro, capacity only has 20GB, it is all tense to install the operating system, but just accord with the requirement for buffering the minimum capacity 18.6GB of technology of hard disk of the solid condition. Users can not see an incantation of the hard disk of the solid condition while opening this technology, will totally use it as cache of the hard disk.

The ten correct decision of 09 years of Microsoft: Win7 should be listed on board
Introduction: U.S.A. IT websites eWeek write articles today, enumerate 10 great correct decision that Microsoft will make in 2009, Windows 7, with answeringBing among them Issue appear on the list.
The following is the article summary:
It is not difficult to condemn Microsoft greatly, the failure of Vista causes enterprises and consumers to migrate other operating systems or continue using the old edition XP, the market share of IE is gliding constantly, and Windows Mobile advantage in the field of intellectual mobile phone is being exhausted, say it is not a mistake that Microsoft is desperate.
But not all bad thing for Microsoft in 2009. In fact, what Microsoft does in 2009 is fairly good: Release new style Windows 7 operating systems, sign with Yahoo and search for the cooperative agreement. The most important thing is, Microsoft will possess more motive force in 2010. The following is 10 great correct decision which Microsoft will do in 2009:
1,Release Windows 7
The manifestation of Vista is quite terrible, but Windows 7 is different to some extent, this operating system comes on stage perfectly, the trend of events has totally overlayed snow leopard’s operating system of the apple. As to Microsoft, this is successful issue, make the development of the business of its operating system step into the right path again.
2,Windows 7 is superior to Vista
Windows 7 is a very outstanding operating system. Its column of task can be improved, usability far exceeds Vista too, security has been promoted by a wide margin too, and the price is within the acceptable range. Though Vista should reach the result the same as Windows 7 originally, it is always better than to less than to be late, so, Windows 7 is still liked by users.
The development that Microsoft must answer is very excellent. It is totally a section of products not essential that Live searches for, but possessed some outstanding functions at the beginning should release, for example visual search. Must promote by a wide margin during the competition with valley song map too in conformity with the map. It is expected to fully develop talents that 2010 will answer.
4,Cooperate with Yahoo
Though the distance finishes also taking some time finally, it is probably most important a decision that Microsoft will do to cooperate with Yahoo in 2009. Rely on this cooperation, Microsoft will obtain enough market share, will launch the real trial of strength with the valley song. This is a strategic policy, and will have a long-term impact on field of Internet.
5,Conciliate with European Union
Microsoft has been socializing with the multinational government all the time for many years, but the contradiction with European Union is the most thorny one. European Union intends to punish Microsoft and operating system, but pass a series of hard bargain, Microsoft has obtained the comparatively favorable result finally: Offer 12 available browsers to user. This is nothing serious at all for Microsoft, because users will still buy Windows operating system.
6,Pay close attention to security
The safe problem has already become a big soft ribs of Microsoft. Windows is besieged by numerous hostile software, make users complain incessantly and even migrate other operating systems. But the behavior on the safe problem will be pretty good in 2009 in Microsoft. Microsoft has released the free antivirus software Security Essentials, offers various systematic patches to user in time. But there are very long ways in this respect in Microsoft go.
7,Neglect Vista
Vista is probably the biggest mistake that Microsoft has made in the past 10 years, as to Microsoft, this is a disaster. It has destroyed Microsoft and enterprise, consumer and relation among the manufacturer. But in 2009, Vista became history at last. And Microsoft has adopted the correct tactics: Neglect Vista, turn all people’s attention to Windows 7. This is really a wise move.
8,The retail shop opens a business
Because of lacking the retail shop, Microsoft has lost many chances. And in 2009, Microsoft retail shop opened a business at last. Though unable to judge to success or failure of strategy this, Microsoft can thereby promote the relation with user continuously in now, and offer the support of the products. According to this, the opening a business of Microsoft retail shop takes a correct step.
9,Remedy the relation with enterprise’s user
Enterprise’s users are injured the deepest user by Vista. Because of worrying about the destruction that Vista brings, they are forced to operate XP. when planning to put out Windows 7 in Microsoft with hardware out of date, have put out the enterprise edition specially. Will find Windows 7 to enterprise’s user’s extraordinary friendship after these users try, ” XP mode ” among them It is the best identification.
10,Control this market of Net surfing
Net surfing is originally the most active field of PC market at present. Linux once occupied the leading factor on this market for a time, but in the past 1 years, Microsoft expanded this field in a more cost-effective manner, and developed Windows 7 the ABC of edition, specially used for surfing the Net one.

Windwos7 intelligence establishes restoration point Save the space of hard disk
At Windows XP age, users can solve and back up and reduce through Ghost way. But as the operating system enters the Windows 7 times, use Ghost way to back up and reduce, it is good to obviously not as good as the restoring function attached of the system. The problem is after launch system, reduce in 7 Windows, it will establish restoration point acquiescence cycle one day automatically . The more restoration point is, just mean the space of hard disk will be smaller and smaller.
Therefore, we can consider letting Windows 7 establish the restoration point ” intelligence ” automatically Unless some, for example system every day establish by each in acquiescence, can’t revise for or not establishing once a day every two days.
General knowledge: Different Windows 7 restoration point
Perhaps some users do not know, do not establish restoration point automatically under Windows 7 default situation, must open relevant permitted service wonder how to open manually manually? Please continue paying close attention to ZOL software
Operate the registration table, unfold to the following branch sequentially: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft \Windows NT\CurrentVersion\SystemRestore.
Then found and doubled click ” RPSessionInterval ” in window on the right side ,Can see systematic acquiescence is in springing the window ” 0″ Unit second,the decimal system:
Fig. 2In Fig. 2, ” 172800 ” Representatives are 172800 seconds, only two it. If you want to let Windows 7 establish restoration point every three days, please input ” 259200 ” under the decimal system Can. So as to analogize.
Editor’s comments:
Is not very suitable for Windows 7 in Ghost, but Windows 7 reduces acquiescence and sets up automatically not under very rational situation, through revise registration table, reach, let 7 Windows ” whether intelligence reduce ” Purpose,come at present and say whether whether it is, there are relatively getting better method on every one.
