The first of the series of Intel microprocessors MIC, called Knights Corner , can inaugurate a new era. With the size of a conventional microprocessor, this beast of more than 50 cores can generate 1 teraflop of processing power in a 22nm structure.
We hear all the time and infrastructure technologies that are constantly renewed, evolving what we know today as computer mass use, but only a few developments are important enough to revolutionize, at least in part, today's desktop computer. The chips have much to do in this area, where we attended with the same sense of wonder to micros 2, 4, 6 and up to eight cores, but when we talk about the future, fingers do not give us to count the cores Intel has been introduced into the Knights Corner . Put it together: Auditors-TA-CIN. Yes, Intel has managed to attach (more than) fifty processing cores on a single chip without the leave of the size standards for microprocessors currently see earthly, because this is from another planet.
22 nanometers is the structure of this new Intel microprocessor introduced in the SC '11 and promises to exceed the modest amount of 1 TFLOPS floating point operations. This dream processing system architecture is included in the MIC (many Integrated core) Intel and is responsible for highly complex computational tasks such as those corresponding to the topography, seismography, simulation scenarios and all these activities you're accustomed to reading next to an article of a supercomputer. This, elKnigths Corner, would be the first product manufactured under the label of MIC architecture, which promises backwards compatibility with x86, even using 3D technology 22nm Tri-gate.
10,000 processors in one hand
The news can not avoid comparison with what happened in 1997, when Intel first reached the teraflop through the use of Intel Pentium Pro 9680 as part of the ASCI Red system Sandia Lab. So all we could do half a decade ago and nearly 10,000 processors, is now in our hands-pun intended-with a single processor. What this development means for computing the future is really amazing , because you just have to think of the multiplication of the power of a supercomputer if instead of using 1000 processors household uses the same amount but like mini supermicroprocesadores Knights Corner and its more than 50 cores without taking up more space than before. Please forgive me, but ... wow.

Watson, IBM's artificial intelligence for the future
As part of the conference's Information on Demand , IBM's annual convention which was very interesting opportunity to attend, the company offered a demonstration of the capabilities of this system capable of responding to questions posed by human natural language.
Watson took only a few months ago a famous American television quiz, Jeopardy! , where easily defeated two of the best contestants in the history of the program and answered questions in a time less than three seconds .. Can be configured in different ways, Watson utiliiza all the innovations in analysis and data management at IBM, either by connecting to databases and encyclopedias stored on hard drives, such as internet, with this almost unlimited source is. Watson's role is precisely for this reason, the access, select and process information more appropriate to the situation or interaction required.
The intent of IBM is that in the future, Watson is able to interact in human terms to a large amount of processing s. Although experts as the philosopher John Searle has already shown its logical skepticism to the alleged human intellectual abilities that this system aims to make real IBM seems intent to HAL 9000, the famous board computer that Stanley Kubrick dreamed for his film 2001: A Odyssey the space .
The end of the heating of the computers
Right now one of the great problems of computers, both laptops and desktop, is the warming that occurs when you use many hours. A European research project is developing a system based on nanoconmutadores that could end the uncomfortable and dangerous warming of computers.
The study of structures known as magnetic tunnel has allowed, for example, create ultrasensitive magnetic sensor for reading data stored on hard drives or to create magnetic storage cells in magnetic memory chips nonvolatile (those that do not require electricity continues to store the information). Now, thanks to the development of these complex structures can be used to "control thermoelectric voltages and currents in electronic circuits" explained from the Information Service R & D Community.
These magnetic tunnel structures consist of two magnetic layers separated by a thin insulating layer . Simply controlling the magnetization of the two layers can be controlled also the flow of electrical current through the structure, and not only that. The team of researchers has succeeded in demonstrating that also modifies the heat flux, the amount of heat flowing through the structure, which means that in the future be able to control and prevent overheating that we are accustomed.

Ten basic safety tips computer
Here are some basic tips to computer security for your system, your sensitive information and your data will remain free of infection . From the obvious to the most complex, recommendations on how to protect ourselves, more so belligerent half as the Internet, are very useful. If you practice, the chances of infection will drop considerably.
While these basic safety tips are aimed at computing an audience less experienced Windows user , for being the most widely used system for new computer users and for being the most affected by viruses and threats, ' the rules may come to rest operating systems and each computer operation we want to pursue without jeopardizing our data and system. That said, let's see what they're doing it wrong for your safety and how you can fix it.
1 - Beware of attachments in your email
If you do not know, do not open. With that line of logic, you should stay safe for long e-mails from strange directions or have attachments like. Pps,. Zip,. Exe, etc. As much as you're not having a good time, and the invitation to take miracle pills free look tempting ... Is it worth the risk? Even when an email with attachment that sends you did not expect a well-known, best by any means is to ask if he sent it to be a little safer. Level software, you can do is email scan through your favorite antivirus or antimalware application. Distrust, without paranoia, is a good tool to avoid falling under the yoke of the threats.
2 - Upgrade the software on your system periodically
Newer, more resilient. This should be a perogullo truth, it is as simple as thinking "if I use an application that is out of date three months ago, took three months of unresolved vulnerabilities over", which will make your system more prone to get malware. The reluctance to upgrade software (including operating system) is due to costs, laziness and also, crucially, to oblivion. So it is good to have some applications that check for updates to the software that we installed and we recommend downloading. Upgrading software does not mean that the new version can not come other holes, but is less usual in the previous case. And in the case of operating systems for Windows XP and 7 is illustrative of others.
3 - Create better passwords and change them every six months
More difficult, less predictable. And forced a first place is in your text: "enter a new password." It must appeal to the same password for years for all services to which you subscribe is really risky, if you find one, they discover it. So it's best to create passwords for service or service by gender, in addition to a password manager, forget about "remember password" in public places and use application to create encryption keys that the most nerd at MIT could guess without take him all his life.
4 - Use antivirus and anti-malware applications
We do not want heroes: Use Antivirus. The virus could cost you money or not, but we agree that uses system resources that you might give some headache. But, weighing the risks, an active antivirus is always more effective and safer than a computer without it. For the second case the system is highly dependent on your care, and if we ever fail, you forget or someone uses your system goodbye. There are antivirus everywhere and offer different performances according to cost and use as RAM. Choose the one that suits you. Same with anti-malware applications, Spybot Search and Destroy and MalwareBytes are the dynamic duo comes to the rescue with the signal in the sky it's been three days since the last scan.
5 - It tends to close the session at the end
A login window is also an output window. Humans are curious by nature, and he sees something that is not made available to him, most likely, at least out of curiosity, make use of this gift of becoming. This usually happens at Internet cafes, offices and work in all places where computers are shared. If you open Facebook, Gmail or any other service, get used to close the session before getting out of the chair to leave. This avoids entering into the huge rate of users who lose data leave open their sessions there. A good exercise to build the habit is to do it at home too, every time you wake up the computer, log off.
6 - Avoid private operations in open, public networks
Sharing the connection, but not the data. One of the most complicated for many tourists is on vacation and having to perform banking transactions from the open network of your hotel or from some place open networks. This means comfort, but also possibilities for the shape and copper sniffing assail us bank accounts, social, mail, etc.. in a blink of an eye. To avoid this connection should be avoided, and that's like saying you cut the light in your home so you never get electrocuted. Therefore, it is best to use alternative means such as VPN servers, or more accessible, extensions such as Blacksheep, access only to sites with HTTPS protocol and have the firewall to the best of care.
7 - Enable the firewall on your system
The Great Wall of China was not built for decoration. This sentence should be an invitation to take care of us without putting so many fads over when to be a little curtailed in our comfort. A firewall can be configured completely to the annoyance of his presence will be comforting protection level, because you can change the priority system, add exceptions and if you're on Windows, use alternative applications that give you more possibilities.
8 - Avoid software with recurrent disease associations
CanciónMuyLinda.exe not an MP3: Due to the amount of scams that exist in relation to Web services, applications and what they wish, have a clear idea of what programs do not contribute to your computer a virus and shelter malware, it is somewhat complex. We therefore propose a return to the classics and their alternatives. But as you can not ignore innovation, it is good that you reference a website that you clean the doubts about the legitimacy of software, for while many programs promise to remove malware, it is they themselves who are reported as infections, and poison your system to sell the solution.
9 - disconnect from the Internet when not needed
Minor exposure, lower rate of infection: There are exceptions in droves, but most infections occur when the computers are connected to the network, as spyware and malware perform their actions by communicating with servers or sending information through open ports your connection. So if you want to lose the chance of infection rate and long time use a computer without a network connection (games, design, writing, etc.) or if you're going to sleep or go directly to be absent disconnecting internet you avoid something happening on your system without shutting down the computer. Simple, but 100% effective.
10 - Backs
Better safe than sorry: For given a situation where you lose data due to lack of security policies on your computer, not doing something of everything we've counted up, the most common situation is despair. But if it will be important backups or backups, that when all would be flooded in tears, who did the work and supported the data will take it as one more experience. No VPN, antivirus, win a paranoia that the security provided by the existence of the data to another disk or cloud services. As for software, we made a recommendation to 6 applications to back up your data, choose the one you like and feel calm doing a backup every certain period of time. You can also back up your mail or other social services.
Bonus: Educate those who share your computer with you
The more you know, unless they are wrong: This item is intended to make clear that while there may be a paranoid computer security when you have this in their hands an inexperienced, few of your resources and fulfill its role computer have a good chance of becoming infected. To avoid this, especially for those with a family computer or share in their work, it's best to educate those who have contact with computers in general. Both those who share yours as your environment. Teaching this article, telling your own experience, recommending security software and instructing in the art of being aware of the danger that exists whenever the network cable connected to the computer.
Caring for our systems is a requirement that users have to assume when the creators of the software or operating system have made mistakes, so that security ultimately depends on us.

HP decides to maintain its personal computer division
The computer group Hewlett-Packard (HP), under the new leadership of Meg Whitman announced that finally keep its personal computer division although in August rid of it was raised to focus on producing software . Following a strategic review, HP saw its PC business area is a "key component" to the company and contributes "significantly" to the offer of solutions of the company and its brand value, as explained in a statement.
"HP is committed to PSG (Personal Systems Group, its PC division), and together we are stronger " , said President and CEO, Meg Whitman, who insisted that this decision is right for "consumers, partners, shareholders and employees. " On August 18 HP was announced that weighed options for its computer division, one of which was "the total or partial separation from that business." The news was in response falling to 22% of the shares of the company in the next trading day. Barely a month later, the board dismissed the CEO Léo Apotheker, who after taking office in 2010 had sought to focus on the production of HP software. Whitman, executive of eBay and former candidate for governor of California Republican, replaced Apotheker September 22 to face what HP management considered a "critical moment." HP is the world's leading manufacturer of personal computers, a business that has been stalled globally and sees sales fall down from devices the novel tablet computer. HP without success this year launched its TouchPad tablet, which eventually removed from the shelves along with the rest of their products with WebOS operating system, designed for tablets and phones.
"Together we are stronger"
"It was clear after our analysis to keep the Personal Systems Group is right for our customers and partners, the right thing for shareholders and employees the right thing," he says in a note, which explains his decision. "Together we are stronger" clinched. Lenovo is now the second largest PC maker, according to Gartner followed by Dell.
The explanation, from the words of Whitman, is that the PC business is very engaged in the supply chain of the company and other operations of the firm in Palo Alto. But above all, the personal computer is the distinctive product of the HP brand. Another reason was said on the floor is the high cost of separation outweigh the benefits.
Apotheker's idea, however, relied more on his experience in SAP, specializing in business solutions. That is, in fact, the pillar on which rests the new IBM business model, which is much more profitable to manufacture electronic devices. The tablets and interactive phones are also eating the PC sales.
The challenge, therefore, for Whitman will find the model that allows HP to be profitable in a new market dynamic in which the consumer is changing the way you use the PC. That unit contributed to the company revenues of 40,700 million dollars in 2010. But Apotheker said, the effect of mobile devices "is real."
