Computes and Internet are the key to the Information world we live in. People talk less and chat more on the Internet. Online games are becoming more popular than anybody could ever imagine. Chat rooms are always crowded and emails are the preferred method of sending messages. Messengers are becoming the preferred method of talking across the globe. The earth has gone flat no doubt.
Computers, programming, searches, Internet, downloads, blogging, websites, all these words are becoming so common that no body can imagine that it all started not many years back. Today across all the ages, this is equally popular. Latest innovations are appearing everyday and companies are minting money online. All this was never predicted but this has become a reality.
Is people to people contact is suffering because of Internet? Are we searching for unnecessary information and over loading ourselves? When so much information was not available to us, we could live, isn’t it? Then why do we search for any and everything online? Does that make our life better? In the earlier days, people took time to write letters to each other. Now it is sending a mail, which somehow does not have that personal touch. Language is also suffering because of the new lingo of the cyber world.
I sometime imagine of people living in a peaceful area away from our civilization. Give them computers and connect them with Internet. Will they not lose all the peace they had before?

RAID stands for "Redundant Array of Independent (formerly "Inexpensive") Disks." RAID is a collection of hard drives in a computer that is used for performance enhancement and/or fault tolerance. Windows server versions (Windows NT and 2000 Server, and Windows Server 2003) have built-in support for some levels of RAID, but hardware-based RAID systems provide better performance. The most basic level of RAID uses two hard drives to increase performance, while higher levels store data on two or more drives so that if one fails, the data won't be lost. SCSI drives are usually used in RAID systems. In hardware-based RAID systems, it is common for the drives to be removable; they are kept in a caddy that is accessible through an opening in the case. When one fails, it can easily be replaced. More advanced systems employ hot-swappable drives. These are drives that can be removed and replaced without shutting down the system. Naturally, all this technology is much more expensive than standard PCs, so it is used mainly in business and government situations in which downtime and/or data loss would be catastrophic to the operation of the organization. For more information on RAID, see raidweb.com, and search the Web for more articles; there are many.
If you have more than one computer at home, you are probably better off connecting them or networking them together to use the same resources and receive the same internet connection. A home network is very easy to build. Here are some tips.
There are two main types of home networks, wired and wireless. While wired home networks are popular, but they require you to run wires from one computer to another. You might have to drill holes in a wall or run wire under the carpet.
If you don’t want cords running all over the place, you can easily get rid of them with a wireless home network. Wireless home networks are extremely simple to set up. You only need a wireless router and a wireless networking card for each additional computer you would like to hook up. Most wireless networks can send and receive data lightning fast at megabytes per second.
Wireless networks are extremely inexpensive, you can hook up a few computers for less than $200. The great part of wireless networks is that all computers on the wireless network can use the same internet or other resources such as a scanning machine and printer. So if you are looking for a great way to share data and resources among your home computer, choose to build a home network.

Shure's Music Phone Adapter (MPA) is our favorite iPhone solution, since it lets you use the headphones you're most comfortable with. It has an iPhone-compatible jack at one end and a microphone module with an Answer/End/Pause button and a female 3.5mm audio jack for connecting to your own headphones. We connected the adapter to the Shure SE110 in-ear headphones, whose cabling is modular; the top half is fairly short, so when used with the adapter, the cable is the right length, but the mic lays around your navel. The MPA comes with three different sizes of foam and silicone tips and a carrying pouch. Shure's coated memory-foam tips are the most comfortable on the market, and they stay in your ear securely--especially if you wear the cables over the tops of your ears.

LONDON (AP) — The loose-knit hacking movement "Anonymous" claimed Sunday to have stolen thousands of credit card numbers and other personal information belonging to clients of U.S.-based security think tank Stratfor. One hacker said the goal was to pilfer funds from individuals' accounts to give away as Christmas donations, and some victims confirmed unauthorized transactions linked to their credit cards.
Anonymous boasted of stealing Stratfor's confidential client list, which includes entities ranging from Apple Inc. to the U.S. Air Force to the Miami Police Department, and mining it for more than 4,000 credit card numbers, passwords and home addresses.
Austin, Texas-based Stratfor provides political, economic and military analysis to help clients reduce risk, according to a description on its YouTube page. It charges subscribers for its reports and analysis, delivered through the web, emails and videos. The company's main website was down, with a banner saying the "site is currently undergoing maintenance."
Proprietary information about the companies and government agencies that subscribe to Stratfor's newsletters did not appear to be at any significant risk, however, with the main threat posed to individual employees who had subscribed.
"Not so private and secret anymore?" Anonymous taunted in a message on Twitter, promising that the attack on Stratfor was just the beginning of a Christmas-inspired assault on a long list of targets.
Anonymous said the client list it had already posted was a small slice of the 200 gigabytes worth of plunder it stole from Stratfor and promised more leaks. It said it was able to get the credit card details in part because Stratfor didn't bother encrypting them — an easy-to-avoid blunder which, if true, would be a major embarrassment for any security-related company.
Fred Burton, Stratfor's vice president of intelligence, said the company had reported the intrusion to law enforcement and was working with them on the investigation.
Stratfor has protections in place meant to prevent such attacks, he said.
"But I think the hackers live in this kind of world where once they fixate on you or try to attack you it's extraordinarily difficult to defend against," Burton said.
Hours after publishing what it claimed was Stratfor's client list, Anonymous tweeted a link to encrypted files online with names, phone numbers, emails, addresses and credit card account details.
"Not as many as you expected? Worry not, fellow pirates and robin hoods. These are just the 'A's," read a message posted online that encouraged readers to download a file of the hacked information.
The attack is "just another in a massive string of breaches we've seen this year and in years past," said Josh Shaul, chief technology officer of Application Security Inc., a New York-based provider of database security software.
Still, companies that shared secret information with Stratfor in order to obtain threat assessments might worry that the information is among the 200 gigabytes of data that Anonymous claims to have stolen, he said.
"If an attacker is walking away with that much email, there might be some very juicy bits of information that they have," Shaul said.Lt. Col. John Dorrian, public affairs officer for the Air Force, said that "for obvious reasons" the Air Force doesn't discuss specific vulnerabilities, threats or responses to them.
"The Air Force will continue to monitor the situation and, as always, take appropriate action as necessary to protect Air Force networks and information," he said in an email.
Miami Police Department spokesman Sgt. Freddie Cruz Jr. said that he could not confirm that the agency was a client of Stratfor, and he said he had not received any information about a security breach involving the police department.
Anonymous also linked to images online that it suggested were receipts for charitable donations made by the group manipulating the credit card data it stole.
"Thank you! Defense Intelligence Agency," read the text above one image that appeared to show a transaction summary indicating that an agency employee's information was used to donate $250 to a non-profit.
One receipt — to the American Red Cross — had Allen Barr's name on it.
Barr, of Austin, Texas, recently retired from the Texas Department of Banking and said he discovered last Friday that a total of $700 had been spent from his account. Barr, who has spent more than a decade dealing with cybercrime at banks, said five transactions were made in total.
"It was all charities, the Red Cross, CARE, Save the Children. So when the credit card company called my wife she wasn't sure whether I was just donating," said Barr, who wasn't aware until a reporter with the AP called that his information had been compromised when Stratfor's computers were hacked.
"It made me feel terrible. It made my wife feel terrible. We had to close the account."Wishing everyone a "Merry LulzXMas" — a nod to its spinoff hacking group Lulz Security — Anonymous also posted a link on Twitter to a site containing the email, phone number and credit number of a U.S. Homeland Security employee.
The employee, Cody Sultenfuss, said he had no warning before his details were posted."They took money I did not have," he told The Associated Press in a series of emails, which did not specify the amount taken. "I think 'Why me?' I am not rich."
But the breach doesn't necessarily pose a risk to owners of the credit cards. A card user who suspects fraudulent activity on his or her card can contact the credit card company to dispute the charge.
Stratfor said in an email to members, signed by Stratfor Chief Executive George Friedman and passed on to AP by subscribers, that it had hired a "leading identity theft protection and monitoring service" on behalf of the Stratfor members affected by the attack. The company said it will send another email on services for affected members by Wednesday.
Stratfor acknowledged that an "unauthorized party" had revealed personal information and credit card data of some of its members.
The company had sent another email to subscribers earlier in the day saying it had suspended its servers and email after learning that its website had been hacked.
One member of the hacking group, who uses the handle AnonymousAbu on Twitter, claimed that more than 90,000 credit cards from law enforcement, the intelligence community and journalists — "corporate/exec accounts of people like Fox" News — had been hacked and used to "steal a million dollars" and make donations.
It was impossible to verify where credit card details were used. Fox News was not on the excerpted list of Stratfor members posted online, but other media organizations including MSNBC and Al-Jazeera English appeared in the file.
Anonymous warned it has "enough targets lined up to extend the fun fun fun of LulzXmas through the entire next week."
The group has previously claimed responsibility for attacks on credit card companies Visa Inc. and MasterCard Inc., eBay Inc.'s PayPal, as well as other groups in the music industry and the Church of Scientology.

(Reuters) - Facebook launched a new suicide prevention tool on Tuesday, giving users a direct link to an online chat with counselors who can help, the company said.
Friends are able to report suicidal behavior by clicking a report option next to any piece of content on the site and choosing suicidal content under the harmful behavior option, Facebook spokesman Frederic Wolens said.
Facebook will then email the user in distress a direct link for a private online chat with a crisis representative from the National Suicide Prevention Lifeline as well as the group's phone number.
The new tool gives people who may not be comfortable picking up the phone a direct avenue to seek help.
"This was a natural progression from something we've been working on for a long time," Wolens said.
Users also have the ability to report suicidal behavior by going to the site's Help Center or search for suicide reporting forms. They can also use reporting links around the site.
Worried friends who reported the behavior will also receive a message to say it is being addressed, Wolens said.
Facebook, the most popular Web-based social networking site, has more than 800 million active users worldwide. The Palo Alto, California-based company was co-founded by Mark Zuckerberg in 2004.
The new suicide reporting tool will be made available to people who use Facebook in the United States and Canada. Wolens said that all reporting on the site is done anonymously and so a distressed user will not know who reported the suicidal content.
Nearly 100 Americans die by suicide every day, according to the Surgeon General of the United States.
In the past year, more than 8 million Americans 18 or older had thought seriously about suicide, according to a blog post by the Surgeon General accompanying the release of the new Facebook tool.

What those companies may need to do is identify a handful of the top killer apps in the existing market and spend the right amount of money to make sure that those apps migrate to their own platforms. Providing powerful tools that can facilitate app migration should probably be at the top of their to-do list. After that, the market will become very much like the car industry, a matter of status, gadgetry, trend and fashion. Eventually, there will only be one basic OS, preferably a user-customizable OS
In studying for your CCNA exam and preparing to earn this valuable certification, you may be tempted to spend little time studying static routing and head right for the more exciting dynamic routing protocols like RIP, EIGRP, and OSPF. This is an understandable mistake, but still a mistake. Static routing is not complicated, but it's an important topic on the CCNA exam and a valuable skill for real-world networking.
To create static routes on a Cisco router, you use the ip route command followed by the destination network, network mask, and either the next-hop IP address or the local exit interface. It's vital to keep that last part in mind - you're either configuring the IP address of the downstream router, or the interface on the local router that will serve as the exit interface.
Let's say your local router has a serial0 interface with an IP address of 200.1.1.1/30, and the downstream router that will be the next hop will receive packets on its serial1 interface with an IP address of 200.1.1.2/30. The static route will be for packets destined for the 172.10.1.0 network. Either of the following ip route statements would be correct.
R1(config)#ip route 172.10.1.0 255.255.255.0 200.1.1.2 (next-hop IP address)
OR
R1(config)#ip route 172.10.1.0 255.255.255.0 serial0 ( local exit interface)
You can also write a static route that matches only one destination. This is a host route, and has 255.255.255.255 for a mask. If the above static routes should only be used to send packets to 172.10.1.1., the following commands would do the job.
R1(config)#ip route 172.10.1.1 255.255.255.255 200.1.1.2 (next-hop IP address)
OR
R1(config)#ip route 172.10.1.1 255.255.255.255 serial0 ( local exit interface)
Finally, a default static route serves as a gateway of last resort. If there are no matches for a destination in the routing table, the default route will be used. Default routes use all zeroes for both the destination and mask, and again a next-hop IP address or local exit interface can be used.
R1(config)#ip route 0.0.0.0 0.0.0.0 200.1.1.2 (next-hop IP address)
OR
R1(config)#ip route 0.0.0.0 0.0.0.0 serial0 ( local exit interface)
IP route statements seem simple enough, but the details regarding the next-hop IP address, the local exit interface, default static routes, and the syntax of the command are vital for success on CCNA exam day and in the real world.
