However, some Office 2010 users may encounter installation issue where installation process of Office 2010 halts unexpected before completion, and then stuck forever and indefinitely despite hitting “Cancel” button or rollback the installation.

To make matter worse, it’s impossible to start the installation of Office 2010 again, as install wizard won’t start. There is no entry of Office 2010 in Add and Remove Programs or Programs and Features list too, so end-user cannot uninstall or rollback the failed Office 2010 install attempt. It’s also impossible to install any other version of Office (such as Office 2007) to supersede, overwrite or replace the corrupted Office 2010 installation, the installation wizard cannot continue as another setup was not completed.
It’s also possible that users who messed around with the registry keys and/or license files of Office 2010 will render the Office 2010 installation not working, and any attempt to reinstall with have installer rolls back with error message of “License cannot be verified”.

For those who want the security of access to the Facebook site more secure.

Encrypt the Web: Install HTTPS Everywhere

HTTPS Everywhere is a Firefox extension produced as a collaboration between The Tor Project and the Electronic Frontier Foundation. It encrypts your communications with a number of major websites.
Many sites on the web offer some limited support for encryption over HTTPS, but make it difficult to use. For instance, they may default to unencrypted HTTP, or fill encrypted pages with links that go back to the unencrypted site.

The HTTPS Everywhere extension fixes these problems by rewriting all requests to these sites to HTTPS.

The plugin currently works for:
  • Google Search
  • Wikipedia
  • Twitter
  • Facebook
  • The New York Times
  • The Washington Post
  • Paypal
  • EFF
  • Tor
  • Ixquick

(and many other sites)

Text, don't talk! To reduce cellphone radiation, also buy low-emitting phone

"Listen more, talk less"  isn't just a Dale Carnegie-like way to win friends and influence people. It, along with "text, don't talk," is also a way to reduce radiation exposure from cellphones. Another way: buy a low-emitting phone.

Cellphones emit radiation to send voice and text messages, and some studies of frequent users suggest  increased risks for brain and mouth tumors as well as children's behavior problems, according to the Environmental Working Group, a non-profit government watchdog group.

"Until scientists know much more about cellphone radiation, it's smart for consumers to buy phones with the lowest emissions," the Washington-based group says. It recently updated its online consumer guide, covering more than 1,000 phones on the market, to include 2010 models.
The popular iPhone scores in the middle range, as noted on a list of new phones most recommended by tech experts. If you're not sure what model your phone is, take out the battery. Model numbers are often listed there.

The guide lists the best and worst phones. Among the lowest-emitters are Sanyo Katana II, Samsung Rugby and Blackberry Storm 9530. The highest include Blackberry 8820, Motorola i880 and Palm Pixi.
When the Environmental Working Group released a report last year on cellphone radiation, the wireless industry's lobbying association CTIA issued a statement saying wireless devices do not pose a health hazard, according to a USA TODAY story.

The Federal Communications Commission sets standards for cellphone radiation, requiring they be rated at 1.6 watts per kilogram or less. It doesn't require device makers to reveal radiation levels.
 The Environmental  Working Group offers tips for reducing exposure, such as texting and listening rather than talking.  Aside from buying a low-emitting phone, it recommends:
    Headsets emit much less radiation than phones. Choose either wired or wireless (experts are split on which version is safer) using our cellphone headset guide. Some wireless headsets emit continuous, low-level radiation, so take yours off your ear when you're not on a call. Using your phone in speaker mode also reduces radiation to the head.
    Your phone emits radiation when you talk or text, but not when you're receiving messages. Listening more and talking less reduces your exposures.
    Hold the phone away from your torso when you're talking (with headset or speaker), not against your ear, in a pocket, or on your belt where soft body tissues absorb radiation.
    Phones use less power (less radiation) to send text than voice. And unlike when you speak with the phone at your ear, texting keeps radiation away from your head.
    Fewer signal bars on your phone means that it emits more radiation to get the signal to the tower. Make and take calls when your phone has a strong signal.
    Young children's brains absorb twice the cellphone radiation as an adult's. EWG joins health agencies in at least six countries in recommending limits for children's phone use, such as for emergency situations only.
    Radiation shields such as antenna caps or keypad covers reduce the connection quality and force the phone to transmit at a higher power with higher radiation.

    Talking Out Loud Improves Memory Retention

    Talking Out Loud Improves Memory Retention
    Libraries are quiet places because people are often concentrating intensely, but according to a recent paper, muttering to yourself and talking about things out loud helps improve your memory and the knowledge that you retain.

    You may look a little odd talking to yourself, but studying out loud improves information retention by differentiating bits of knowledge. According to the article:
    In this paper, these researchers document what they call the production effect. They looked at people's memory for items like a list of words. They found that if people studied the list by reading half of the words silently and the other half by saying the words out loud, that he words spoken aloud were remembered much better than those that were read silently.
    The production effect works because it makes part of the list of items more distinctive. The words you speak aloud are now translated into speech and you have knowledge of producing the items as well as a memory of hearing them. All of this information makes your memory for the spoken items more distinct from the rest of the items that were read silently.

    30,000 Quit Facebook In Protest

    A group protesting Facebook's privacy policies said Monday more than 30,000 people had heeded its call to quit the social networking giant.

    SAN FRANCISCO (AFP) - – A group protesting Facebook's privacy policies said Monday more than 30,000 people had heeded its call to quit the social networking giant.
    "For us it comes down to two things: fair choices and best intentions. In our view, Facebook doesn't do a good job in either department," the organizers, who did not identify themselves, said on their website for Monday's "Quit Facebook Day."
    "Facebook gives you choices about how to manage your data, but they aren't fair choices."
    The group said at 2300 GMT that 32,749 had dropped out of the Facebook universe. is visited monthly by 540 million people, or slightly more than 35 percent of the Internet population, according to Google data.
    Facebook is overhauling privacy controls in the face of a barrage of criticism that it is betraying the trust which has made it the world's biggest social network.
    Facebook redesigned its privacy settings page to provide a single control for content and "significantly reduce" the amount of information that is always visible to everyone.
    Facebook also said it is giving users more control over how outside applications or websites access information at the service.
    Critics continue to call for Facebook to make all user information private by default and then let people designate what they want to share case-by-case in an "opt-in" model.
