“Your support is how we pay our bills. People like you, giving five dollars, twenty dollars, a hundred dollars. Thank you for helping us,” said Sue Gardner, Executive Director of Wikimedia Foundation. “We’re the #5 most-popular site in the world — we operate on a tiny fraction of the resources of any other top site. We will use your money carefully and well, I promise you.”

“It is our most successful campaign ever, continuing an unbroken streak in which donations have risen every year since the campaigns began in 2003,” he said, adding that Wikimedia had received $20 million in donations from readers. This is up from $4.5 million in 2008, and the number of donors is said to have increased ten-fold since that same year.

Mobile Internet  Provider is SingTel.

MobileAP
(slowest)
Download : 0.60 Mbps
Upload: 0.36 Mbps

It is able to use for email, web browsing and Web Application. Not too bad, able to use.
It is hassle-less approach on the move because no cable is required to attached but the battery will be used out.
USB Tethering
(Faster)
Download: 2.62 Mbps
Upload: 1.04 Mbps

It is able to use for email, web browsing and Web Application.It has better speed than MobileAP.
It is required to attach USB cable and when media scanning processs is initiated, the Tethering is closed.
It is need to follow the following steps.

Go to Tethering and portable hotspt
Connect USB cable
When the option is active, enable it.

pdaNet
(3rd party application required, the more faster than USB Tethering.)
Download : 4.63 Mbps
Upload: 0.70 Mbps

It is required to attach USB cable.

It is a kind of collaboration mobile application for private members.

Right away you’ll be asked to set up your first board, which is a stream of content only people you invite can view. You can set up as many boards as you like and invite people to specific projects. It comes with a few nice settings, including push notification “quiet hours” that will automatically disable notification during times of your choosing. It’s also non-existent on the web and everything is stored on Glassboard’s servers, so if you’re working on a project with a few people and want to communicate on your mobile but still have privacy, this should do the trick.

Simply download DBAN, drop it onto a blank CD or DVD, and use it to boot your PC.
Mac, If you’re using a Mac OS DVD, just insert the DVD and hold down the C key on startup to boot to the DVD instead of the hard drive.

By default, DBAN does a three-way pass writing zeroes to the hard drive, but you can press M on the drive select screen to choose the number of passes DBAN performs. If you prefer the 7-way pass that Mac users perform, select thre DOD5520-22 M method, which does the same thing. The Gutmann Method performs a similar 35-way wipe. As on the Mac, the more wipes you do, the longer the process will take. We recommend sticking to the 3 or 7-way wipe-it offers a good balance between security and speed, and will help you get those systems out of your house and to your local charity sooner.

Zero Out Data is one secure method, and will write over all of the data on your drive with zeroes on a single pass. It’s the least secure of the three options, but it’s also the fastest. The 7-way pass does the same thing, but repeats the process seven times. This is probably the best balance between speed and security, as it makes it fairly difficult to retrieve any of the information you previously had on the drive. We recommend going this route, especially if you have the time to let each system do the 7-way pass. The 35-pass erase takes a very long time to complete, but it’s definitely the most secure method. If you’re donating the systems to charity, you probably don’t need to go to this extent.

It’s important to note that none of these methods, even the 35-way write, will likely be enough to keep your data out of the hands of someone with the right equipment, time, and training (a company like DriveSavers, for example) or someone with the budget to hire them. Since you said you don’t want to remove the drives first and you expect to donate these systems in usable condition, we’re assuming that you don’t have any enemies who desperately want your data, or that the FBI or NSA aren’t waiting for you to dispose of those computers so they can try to figure out what you had on them. In either case, nothing we can suggest here will help you.

It is not the excel file issue. It is Excel program issue.

How this issue suddenly triggered?

• Is it user issue?
• Is it due to MS security patches ?

Apple had better access control, application provenance and encryption in iOS while Google was better at application isolation, Khoi Nguyen, group product manager in the enterprise mobility group at Symantec.

“The project wasn’t about determining which platform was better,” Nguyen said. Symantec was more interested in examining the core security architecture to analyze strengths and potential vulnerabilities, Nguyen said.

Both platforms enforce access control policies via passwords, Symantec found, although the iOS offers more options for protecting data, such as an automatic data wipe after a specified number of failed password attempts.

Apple’s certification and rigid control over what applications can be posted on the App Store protected users, Nguyen said. The iTunes App Store acts as a certificate authority to sign the app and is the only source for non-jailbroken iOS devices. Google’s “less rigorous” system helped trigger the increase in Android malware because it was easier to get malicious apps onto the Android Market, Symantec found.

While iOS apps are forbidden to read or write to other apps or the operating system and have limited access to the SIM card or the kernel, they can perform a wide range of actions such as accessing the Internet, getting the phone number, looking at the calendar and controlling the video camera without requesting permission from the user. This can raise potential privacy flags.

Android apps are blocked from accessing most system services unless the user explicitly grants permission. When the user tries to install an app, it is shown a list of permissions the app needs, so the user knows up front exactly what the app will do on the device, such as sending SMS messages or accessing the Internet.

While Android gives the user control over what to allow on a case-by-case basis, it also runs the risk of overwhelming non-technically savvy users by asking them to make security decisions, Nguyen said.

While mobile devices are designed to be more secure, the way they are used makes them more insecure than laptops and desktops within the enterprise. Regularly synchronizing devices with cloud services and home desktop computers so that all the information is always accessible means sensitive corporate data on those devices are being exposed to systems the IT department has no control over, Symantec said. The devices are more vulnerable because they travel more than laptops, are easier to steal and conceal and easier to break into once stolen, according to Symantec.

Lower prices could also help draw renewed interest in netbooks, which are small and low-powered laptops for basic word processing and Internet surfing.
