UAE telecom body raises issue of BlackBerry misuse

Certain BlackBerry applications allow people to misuse the service, causing serious social, judicial and national security repercussions, the Telecommunication Regulatory Authority said.


The Telecommunication Regulatory Authority (TRA) has said BlackBerry operates beyond the jurisdiction of national legislation, as it is the only device operating in the UAE that immediately exports its data off-shore and is managed by a foreign, commercial organisation.

A statement from the TRA said the introduction of BlackBerry in the UAE in 2006 pre-dates the 2007 introduction of the UAE’s Safety, Emergency and National Security legislation, which regulates BlackBerry applications in the UAE.

A new star from Google - People Hopper

People Hopper is a new application for Orkut that lets you take your profile image and 'morph' it into your friend's–using publicly available images from other Orkut users along the way. It is a fun app that also allows you to make new connections–since the images that show in your Hopper all come from people who have chosen to make their profiles public, you can click through to learn more about them and reach out to them. You can also morph one friend into another. No computer graphics are used to generate the path.

To be able to use People Hopper, one needs to have an Orkut account. If you don't already have one, create a new account here. Then, you can add the gadget by clicking on "add apps" under the "more" menu, or simply click here to use people hopper.

To generate a 'morph', People Hopper uses image matching technology. First, faces are automatically detected in public profile images and normalized for improved contrast and size. Then, for each image, we find other publicly available profile images that are similar to one another. Then, when you pick a friend you want to be your end match, we just hop along similar public images, step-by-step, until the connection is made! You can think of it as an image graph between friends, similar to the friendship graph already on Orkut. We don't use any face-specific features or metrics during this process. It is just a simple matching to find similar pictures.

The quality of the path depends on two main factors: the appearance of faces in profile images of Orkut users and the similarity measure used for image matching. Since we cannot control the appearance of profile images, it may happen that for a particular image there exists no visually similar image in the database. Developing better similarity measures is a topic of continuing research.

New gadget allows soldier to "See with his Tongue"

Lance Corporal Craig Lundberg was blinded by a rocket propelled grenade while on patrol in Basra in Iraq during 2007 but thanks to new glasses which is called the Brainport, the Blind soldier can now navigate his surrondings using his tongue. This new device is a mere technological marvel, the Brainport is a miniature video camera and sensory equipment works by converting visual images into a series of electrical pulses which are relayed to the wearer via their tongue. Different images are then built using different strength pulses then relays them to the wearer which allows him/her to navigate around objects or grab on to them and pick them up.

Presently the Brainport is only a prototype stage and sends information to 400 points on the tongue which the designers plan to increase to up to 4,000 points for clearer images in the future.

Setup your own Proxy Server Free

A simple Google search and you’ll find dozens of really good PHP scripts on the Internet to help you create proxy servers in minutes for free. The only limitation with PHP based proxies is that you require a web server to host the proxy scripts and second, you also need a domain name to act as an address for your proxy site.

If you don’t own a domain or server space, you can still create a personal proxy server for free and that too without requiring any technical knowledge.



Create a Free Proxy Server with Google App Engine


Here’s one such proxy site that you can build for your friends in China or even for your personal use (say for accessing blocked sites from office). This is created using Google App Engine and, contrary to what you assume, the process is quite simple.

Create a Free Proxy Server with Google App Engine
Step 1: Go to appengine.google.com and sign-in using your Google Account.

Step 2: Click the “Create an Application” button. Since this is your first time, Google will send a verification code via SMS to your mobile phone number. Type the code and you’re all set to create apps with Google App Engine.

Step 3: Choose a sub-domain* that will host your proxy server. Make sure the domain is available, agree to the Google Terms and click save. The sub-domain is also your App ID that will uniquely identify your proxy application.

For this example, we’ll use blog4info-server as the App ID though you are free to choose any other unique name.

Step 4: OK, now that we have reserved the ID, it’s time to create and upload the proxy server application to Google App Engine. Go to python.org, download the 2.6.4 MSI Installer and install Python.

Step 5: Once Python is installed, go to code.google.com, download the Google App Engine SDK for Python and install it.


Step 6: Download this zip file and extract it to some folder on your desktop. The zip file, for the curious, contains a couple of text files (written in HTML and Python) that you can read with notepad.

Step 7: Start the Google App Engine Launcher program from the desktop and set the right values under Edit –> Preferences (see screenshot above).

Step 8. Click File –> Add Existing Application under the Google App Launcher program and browse to the directory that you created in Step 6. Click the Edit button and replace “YOUR_APP_ID” with the ID (sub-domain) that you reserved in Step 3.

Step 9: Click Deploy and your online proxy server is now ready for use. You can experience it live and if any of the steps don’t make sense, please refer to the following video screencast (available in 720p HD).


You can edit the main.html file to change the appearance of your proxy server and you can even add Analytics and AdSense code to your proxy server in case it gets popular on the web. The application is currently open to all users but you can add a layer of authentication so that only users who are logged-in into their Google Accounts can use your web proxy server.

If you have made any changes to your HTML files, you can upload the latest version to Google App Engine either by clicking the “Deploy” button again or use the following command -- appcfg.py update

Apple's first device to use its iBookstore service and companion iBooks ebook reading application, the iPad has been compared to Amazon's Kindle.

Availability
In an e-mail to customers at the time of launch, Apple wrote:
Application availability and pricing are subject to change. This device has not yet been authorized as required by the rules of the Federal Communications Commission. This device is not, and may not be, offered for sale or lease, or sold or leased, until authorization is obtained. -Apple , Wired News

The iPad is to go on sale at the end of March 2010 (Wi-Fi version, worldwide) and end of April (Wi-Fi + 3G version, in the United States and some other countries. International 3G prices are to be announced summer 2010. The Wi-Fi + 3G iPad will be unlocked so it can be used on other mobile carriers that support GSM micro-SIMs. 3G will be provided in the U.S. by AT&T and sold with two prepaid contract-free data plan options: one for unlimited data and the other for 250 MB/month at half the price.The plans will be activated on the iPad itself and can be canceled at any time.

Disposable email addresses

Hi friends,
2day I;m gonna disscuss with you about disposable email addresses. Now you can give out your email address around the internet withour any fear. While the website policy clearly states that they “won’t sell your email address to third-parties,” you aren’t feeling very comfortable sharing your private email address with a website that you’ve never heard about before. What do you do then?

There are quite a few websites that offer disposable email addresses for free but my favorite is 10minutemail.com. Just visit the and you’ll get a temporary email address that you can use anywhere on the web just like your regular email address (you can even reply and forward message).

The email addresses will self-destruct after, you guessed it right, 10 minutes. They regularly switch their email server domains – you might have been allotted abc@hello.com today but the alias next day could become xyz@bye.com. This prevents forum administrators from blocking members that use temporary addresses.

Hope that was informative.........

Opera Browser Coming to iPhone

If you want to browse the web on your iPhone (or iPod Touch or the upcoming iPad), the only option is the built-in Safari browser because Apple, until now, won’t approve other browser apps in their iTunes store.


Opera, hoping that Apple will change their policy, has developed a version of the Opera Mini browser for the iPhone and they’ll showing a preview of this iPhone App during the Mobile World Congress that happens in Barcelona next week.
An email from Opera PR says:
“We are thrilled to offer journalists and partners an exclusive preview of Opera Mini for iPhone during the year’s biggest mobile event,” said Jon von Tetzchner, Co-founder, Opera Software.

Safari vs. Opera for iPhone
Opera says Opera Mini for iPhone offers up to six times faster download speeds than Apple’s own browser, and up to 10 times smaller data traffic.

The Opera Mini for iPhone will only be shown to members of the press but Apple will have to approve the app for everyone else to experience Opera on their iPods and iPhones.

That may not happen anytime soon as Opera is yet to submit their Opera Mini iPhone App to the Apple App Store for approval.

Amitabh Bachchan Launches a Voice Blog (DEMO)

Indian superstar Amitabh Bachchan — who is not just a Bollywood icon but also an avid blogger — has now launched a new voice blog called Bachchan Bol where he plans to regular record the latest happenings in his life using his own voice.

Fans of Amitabh Bachchan can dial (022) 505678910 from their mobile or landline phones to hear the actor speak or they can even record their own voice comments. Amitabh Bachchan told the BBC that he would record at least twice a week for his “vocal blog” and that he’ll continue to write his (massively popular) blog just as before.

Bachchan Bol is a premium mobile service so you’ll have to pay around Rs. 6 per minute. This may also mean that phone users outside India currently won’t have the facility to dial into Bachchan’s voice blog.

How Bachchan Bol Service Works

You can think of Bachchan Bol as a pre-recorded podcast. The only difference is that you need a computer with an Internet connection to download podcasts but in the case of Bachchan’s phone blog, all you need is a phone connection which most people in India already have.

Here’s a quick video (in Hindi) that explains how the Bachchan Bol service works .

How to Say ‘No to All’ During File Copy Operations in Windows

While copying or moving a large number of files from one location to another folder in Windows, you may often encounter errors or warning messages saying the file(s) you are trying to copy already exists in the target location.

Windows No to All – Keyboard Shortcut

If you are using a previous version of Windows (like XP or Windows 2000 but not Vista), the default error window will offer four choices – "Yes", "No", "Yes to All" and "Cancel".
There’s no "No to All" button in the File Replacement dialog but you can simply hold down the Shift Key before pressing the No button and Windows will automatically interpret this action as a "No to All" command.
This will be so useful when you are copying a large number of files and folders but don’t want to overwrite content that already exists at the target.




In case of Windows Vista, Microsoft designed a more intuitive warning message with a check box that lets you repeat the same operation on all upcoming conflicts.

The Y2K bug

Hi friends,
As you all know there's a new in front of us... It is gonna be 10 years after the millennium threat (the Y2K threat)...the great milestone in computer's history! Let us recall it.

The Year 2000 problem (also known as the Y2K problem, the millennium bug, the Y2K bug, or simply Y2K) was a notable problem for both digital (computer-related) and non-digital documentation and data storage situations which resulted from the practice of abbreviating a four-digit year to two digits.
In computer program design, the practice of representing the year with two digits becomes problematic with logical error(s) arising upon "rollover" from x99 to x00. This has caused some date-related processing to operate incorrectly for dates and times on and after January 1, 2000 and on other critical dates which were billed "event horizons". Without corrective action, it was suggested that long-working systems would break down when the "...97, 98, 99, 00..." ascending numbering assumption suddenly became invalid. Companies and organizations worldwide checked, fixed, and upgraded their computer systems.
While no globally significant computer failures occurred when the clocks rolled over into 2000, preparation for the Y2K bug had a significant effect on the computer industry. Countries that spent very little on tackling the Y2K bug (including Italy and South Korea) experienced as few problems as those that spent much more (such as the United Kingdom and the United States), causing some to question whether the absence of computer failures was the result of the preparation undertaken or whether the significance of the problem had been overstated.
Many banks have responded to the Y2K problem by forcing full 4-digit year entries on cheque forms, which helps to prevent the error from occurring in accounting environments.

Background

Y2K was the common abbreviation for the year 2000 software problem. The abbreviation combines the letter Y for "year", and k for the Greek prefix kilo meaning 1000; hence, 2K signifies 2000. It was also named the Millennium Bug because it was associated with the popular, rather than literal, roll-over of the millennium, despite the fact that the bug could have occurred at the end of any ordinary century.

The Year 2000 problem was the subject of the early book, "Computers in Crisis" by Jerome and Marilyn Murray (Petrocelli, 1984; reissued by McGraw-Hill under the title "The Year 2000 Computing Crisis" in 1996). The first recorded mention of the Year 2000 Problem on a Usenetnewsgroup occurred Saturday, January 19, 1985 by Usenet poster Spencer Bolles.

The acronym Y2K has been attributed to David Eddy, a Massachusetts programmer, in an e-mail sent on June 12, 1995. He later said, "People were calling it CDC (Century Date Change), FADL (Faulty Date Logic) and other names."

Many computer programs stored years with only two digits, for example, 1980 would be stored as 80. Some such programs could not distinguish between the year 2000 and the year 1900. Other programs would try to represent the year 2000 as 19100. This could cause a complete failure and cause date comparisons to produce incorrect results. Some embedded systems, making use of similar date logic, were expected to fail and cause utilities and other crucial infrastructure to fail.

Some warnings of what would happen if nothing were done were particularly dire:

The Y2K problem is the electronic equivalent of the El Niño and there will be nasty surprises around the globe. — John Hamre, Deputy Secretary of Defense 

Special committees were set up by governments to monitor remedial work and contingency planning, particularly by crucial infrastructures such as telecommunications, utilities and the like, to ensure that the most critical services had fixed their own problems and were prepared for problems with others. While some commentators and experts argued that the coverage of the bug largely amounted to scaremongering, it was only the safe passing of the main "event horizon" itself, January 1, 2000, that fully quelled public fears. Some experts who argued that scaremongering was occurring, such as Ross Anderson, Professor of Security Engineering at the University of Cambridge Computer Laboratory, have since claimed that despite sending out hundreds of press releases about research results suggesting that the bug was not likely to be as big a problem as some had suggested, they were largely ignored by the media.

Programming problem

The practice of using two-digit dates for convenience predates computers.

However there were no major problems reported due to this bug....... tribute to brilliant programmers who saved us!

How to show and use the Shortcuts keys in Word 2007?

In Word 2007, most of the shortcut keys are same from the earlier versions such as Word 2000 and Word 2003. But the interesting thing in Word 2007 is that, Microsoft provides a new look or system for these shortcuts keys. In earlier Word versions, you must be memorized to use the shortcuts keys such as (CTRL + B" to make letters bold and "CTRL + I" to make letters italic). But now do not require planned memorization in latest Word 2007 version. There is a fast, simple, and visual way to find out what you need to press.

Now by pressing the "ALT" button and many options or keyboard shortcuts (containing letters or numbers) will be appear on top of the toolbar buttons.

You will see here, For Example:

Twitter and Facebook for the Computer Shy

How do you use social networks like Twitter and Facebook if you are computer shy or don’t have access to the Internet?

Well, you can use a mobile phone to post updates without a computer but this woman is using something that most of us can’t even imagine — see uses a pen to write her tweets on a piece of paper and then send them to Twitter using a fax machine.

Hard to believe? Watch this news story:


The woman, whose Twitter handle is @dorothy_celery, uses a service from Celery that lets people send and receive email messages through a fax machine without requiring a computer or an Internet connection. Other than email, Celery now works with Twitter and Facebook as well.

The service costs about $8.98 a month and you can not only send tweets via fax but they’ll also fax you back any @replies to your Twitter account.

A Better Disk Defragmenter Utility from Microsoft

One of the reasons why your computer may become slow over time is because the files on the hard drive can become fragmented. Now what’s that?

Disk Fragmentation for Non-Techies
As you start filling your hard-drive with new programs, documents, and other files, the operating system tries to find vacant places on the hard-drive to place these files. Like an artist who breaks a tile into multiple pieces to form a mosaic, your computer will break these file into chunks (or fragments) and store them in different places across your hard drive.

When you load a program or open a file, the computer will have to first assemble these "fragmented" pieces thus decreasing the performance. And fragmentation is not just an issue with your computer’s hard disk but even removable devices like the USB Flash Drive or your external drives can also become fragmented with time.

Alternate Windows Disk Defragmenter from Microsoft
A Disk Defragmenter program helps because it will pre-arrange all the "fragmented" pieces of a file close together thus reducing the time it takes to open files or load programs on your computer.

Now almost every version of Windows includes a disk defragmenter utility but the problem with these built-in tools is that that will defragment the entire hard-drive at once and they’ll ignore files that are smaller than 64 MB. Luckily, Microsoft offers another free but lesser-known utility called Contig (short for contiguous) that lets you have more control over the defragmentation process.



What’s unique about Contig is that it lets you defragment individual files, folders, or the entire hard drive. You can run Contig from the command prompt but if that sounds a bit technical, you can also look at Power Defragmenter – an easy and more visual interface for Contig.

Using Power Defragmenter, you can visually select files, folders, or the drive you wish to defragment, and Power Defragmenter will internally use Contig to perform the defragmentation process. You may use Contig on machines running Windows XP, Vista and Windows 7.

For instance, if I were to defragment all the documents on my disk and none of the other files, the command* will be:

Contig.exe -v -s c:\Users\labnol\Documents\*.*[*] You’ll need to run the utility as an administrator as it will throw an "Access denied" error.

And here’s a detailed output of a standard Contig command that tells you exactly what happens behind the scenes per file.

Unlike other third-party defragmentation tools, Contig uses Windows’ internal defragmentation APIs so it won’t cause disk corruption, even if you terminate the program while its running.

Please note, however, that defragmentation is only recommended for traditional hard drives; computers using newer flash memory based solid-state drives should not use traditional defragmenters. Even though file fragmentation may occur on these drives, it should not impact performance due to the nature of flash memory. Additionally, defragmentation may actually decrease the life of a solid-state drive; however, they cannot cause this on a traditional platter-based hard drive.

Rare Metals Vanishing

If you were wondering how long will global reserves of some important metals that are used in electronic devices last, here’s a clue.

Tantalum is a rare metal that is used in the manufacture of cell phones and camera lenses but you’ll be surprised to know that if every human on the planet were to consume this metal at the same rate an average US resident today, the metal supplies won’t last for more than 20 years.

Similarly, we won’t be left with any stock of Indium, another rare metal used in LCDs and touch-screen displays, after 4 years if the world consumes this metal at the same rate as US today.

This report, which roughly demonstrates how quickly time is running out for some rare and important metals, was original published in New Scientist in 2007.

Armin Reller, a materials chemist, estimates that we have, at best, 10 years before we run out of Indium. Its impending scarcity could already be reflected in its price: in January 2003 the metal sold for around $60 per kilogram; by August 2006 the price had shot up to over $1000 per kilogram.

I-Am-Halal Makes Internet Searching Safe for Muslims and your Kids

Muslims generally use the term “Halal” to designate food items that they are allowed to eat under the Islamic law (like fish). The opposite of “halal” is ‘haraam’, another Arabic term which is used for food products that Muslims are forbidden from eating (like pork).

This page describes in detail how stuff is classified as Halal or Haram according to Islam. And its not just about food, the term Halal can refer to any action that is permitted under the Quran while prohibited actions are known as “Haram”.

A Search Engine for Muslims (and your Kids)
Extending the Halal and Haram concept to the Internet, Ramadan Kareem has created a search engine called I am Halal that might just prevent you (Muslims and Non-Muslims alike) from “accidentally” bumping into any explicit (or “Haram”) content on the Internet.

Unlike Safe Search in Google which simply removes all adult sites from search results, I-Am-Halal, which uses search results from Yahoo, employs a double-layered filter.

When you type a search query (e.g. sex) that can potentially retrieve “haram” search results, the search engine would require you to confirm whether you really want to see those search results. When you say yes, it will fetch the relevant pages but will still filter out content that is not deemed as family-safe.

The search results page will also contain thumbnail images of web pages alongside the site links and description. And in addition to websites, you may also use IAmHalal.com to search for images and news stories on the web.

I am actually quite impressed with “I Am Halal” and, other than the religious side of things, this is something good for your kids as well. For instance, if they type a query that is bound to return explicit results, the search engine would simply refuse to work for that query.

Hope it is a good service.

Turn Google Docs into a Distraction Free Writing Tool

When all you want to do is write, a distraction-free writing tool can come really handy as it will automatically hide all the distractions on the desktop and you can therefore concentrate on your writing.

Dark Room (Windows), Microsoft Word, Write Room (Mac), Internet Writer (Web-based), JDarkRoom (Java), PyRoom (Linux) and Q10 (Portable) are some of the popular distraction-free writing tools for various platforms.

There’s an app as well to help you create that perfect writing environment on an iPhone or iPod Touch.

Distraction-free Writing with Google Docs
If you have Google Docs, you really don’t need to download another text editor as Google Docs offers everything (and even more) that you may need in a perfect distraction free writing tool.

To get started, open this page and click the “Use this Template” button. Now press Ctrl + Shift + F followed by F11 and you are all set to do some creative writing.

If you are interested in the details, here’s how you can quickly turn Google Docs into a online distraction-free writing tool:Step

1: Create a new document in Google Docs and choose “Edit CSS” from the edit menu.

Step 2: Paste the following code into the CSS Box and save.

body {
font: 16px "Courier New";
color: #00ff00 !important;
background: #000 !important;
width: 800px;
margin: 10px auto;
}
Step 3: Now hit Ctrl + Shift + F to remove the menu bar in Google Docs and then hit F11 to turn your browser into full-screen mode. That’s it.

The above example uses green text on a black background. If you like to change the color of text or that of your screen, just edit the color and background property in the CSS to a different hexadecimal value. You may also modify the font-family, size, or the line-height property to adjust the text spacing and other formatting.
