New H.265 Video Format..

2013-02-01T01:00:00.000+05:30

The International Telecommunication Union (ITU) announced its approval of the H.265 video format standard on Friday. The new codec may bring 4K video to broadband and also limit bandwidth usage for HD streaming, offering both higher resolution video and lower data use.

As already announced by the Moving Picture Experts Group (MPEG) in August of last year, H.265 video is designed to divide bandwidth usage in half. The new format is also expected to allow for true HD streaming in places with low connectivity, mobile phones, and tablets. In areas with sufficient broadband, 4K could also be made available to consumers at a rate of 20-30Mbps.

The new codec is a successor to H.264, a common format used for most videos released and streamed online. H.265 is also known as High Efficiency Video Coding (HVEC).

H.265 was created as a collaboration between the ITU Video Coding Experts Group (VCEG) and MPEG. No information has been released regarding the new video format’s date of availability to consumers.

Improve Your YouTube Experience- Chrome Add-Ons

2013-01-30T23:25:00.000+05:30

01.ChromeTunes

YouTube is a great music source, and while it’s pretty easy to find or create music playlists to listen to, the task becomes even easier with this simple extension. ChromeTunes turns YouTube into a bona fide music player, taking away the videos, the comments, the suggestions, and even the need to load youtube.com. After installing ChromeTunes, click on the red play button to start listening to YouTube music.

The ChromeTunes player has two parts: the player itself, which you can see above, and the settings layer, where you can add or remove playlists, search YouTube, and more. The player itself comes loaded with two sample playlists which you can easily move between using the bottom playlist switcher. The player comes complete with all the usual options such as repeat, shuffle, reload and share. You can also view more video information such as views count, likes, and more.

To add new playlists, either click the search and play button on the bottom right, or click the cogwheel button on the top right. From here, you can search YouTube for more playlists and add them to ChromeTunes.

Hovering over the extension’s button will reveal the name of the song currently playing, the artist, and the song’s length.

02.YouTube Preview

So you’re watching your daily dose of YouTube videos, going from one video to the next using the ever-present right sidebar. YouTube’s sidebar is a pretty good source of related and recommended videos, but as good as it is, you often find yourself clicking on videos that look promising, only to find out they’re not really what you were looking for. Sounds familiar? YouTube Preview is a handy little add-on that can help you find out more about a video just from looking at the thumbnail.

The first thing you’ll notice are the colorful green and red bars under each thumbnail. These are indicators of how popular a video is, and represent how many people liked this video out of all the users who’ve rated it. If you hover over the thumbnail, the thumbnail itself will start playing, and you’ll see a small walkthrough of the video. While it’s not like watching the full video, it’s much more informative than just seeing a static thumbnail.

03.YouTube Video Deck

Are you a subscription fiend? If you have many subscriptions on YouTube, keeping track of them all can become somewhat tiresome. YouTube Video Deck is a Chrome app that brings all your YouTube subscriptions under one roof – sort of like Google Reader for YouTube subscriptions. After logging in, you can add all or only some of your subscriptions, and receive notifications when a new video is uploaded.

You can set up the layout to your liking, and check the app every time you’re bored for the newest fixes from your favorite YouTube accounts.

Twitter Launches Vine

2013-01-30T02:00:00.000+05:30

Over the last couple of weeks, we’ve heard rumblings of Twitter launching some kind of video sharing service, and it looks like those rumors have come to be in the form of a cool new service called Vine. For the time being, using Vine to create videos is only available with the Vine iOS app, but Twitter has made it clear that Vine will be coming to other platforms soon.

In keeping with Twitter’s theme, videos created on Vine are very short. In fact, videos can only be six seconds or less. This will keep long-winded videos off the service, and just like tweets themselves, everything needs to get to the point. Between the short video clips, and the fact that the app is able to record sound, it should be easy enough for Vine users to get their point across in the time allotment.

Creating videos is as simple as holding a finger on the screen to record, and letting go to stop. You can stop as few or as many times as you want, so you can record one continuous six second video or a bunch of short clips. It only records while touching, so you can change the shot and tell a brief story though the videos without actually having to do any editing.

The videos are embedded directly in Tweets, just like a photo shared on a supported image service. Videos can be played on the Twitter website or on the Twitter mobile app. However, on the mobile application, the videos do not loop as they do on the desktop version of Twitter.

Here’s an example of a Tweet made with Vine:

https://twitter.com/sideox/status/294511424808550400

One thing Twitter neglects to mention in its official announcement of Vine is that users can also share videos on Facebook. However, my Vine posts were not showing up on my Facebook Timeline. The app comes with its own social network, so users can share videos within the Vine network even if they don’t have a Twitter or Facebook account.

The new Acer Chromebook

2012-11-13T23:05:00.001+05:30

Creating a better, simpler computer and making it available for everyone is at the core of the Chromebook vision. It’s exciting to see people using Chromebooks as the perfect additional computer in the home, and we continue to work with our partners to make them easy-to-use and more affordable. Today, we’re delighted that our partner Acer is introducing a new addition to the Chromebook family: the new Acer C7 Chromebook.

The new Acer C7 Chromebook delivers a hassle-free computing experience with speed, built-in security and the simplicity of automatic updates. It features a full-size keyboard, fully clickable trackpad, an extra bright 11.6-inch display and over 3.5 hours of battery life. Powered by an Intel Core processor, the Acer Chromebook is fast—boots up in 18 seconds, resumes instantly and high-definition videos play smoothly (yes, videos like Gangnam Style in 1080p, in case you’re one of the few left who hasn’t seen it). You can easily store your stuff on the Chromebook or in the cloud, with a 320GB hard drive and 100GB of free storage on Google Drive.*

As you’d expect from a Chromebook, it’s easy to share with others around the home. Moms, dads, siblings or even your roommate can all have separate accounts and simply log in to get things done. And because Chromebooks bring you the best of Google, if you use products like Gmail, Drive, Maps, YouTube and Google+, your stuff is always available and everything just works.

Starting tomorrow, the Acer Chromebook will be available for $199 in the U.S. on Google Play, BestBuy.com and rolling out this week in select Best Buy stores. In the U.K., it’s available on Google Play, Amazon UK, PC World and Currys. We’re working hard to bring it to more countries soon.

Together with Acer, it’s great to welcome the newest addition to the Chromebook family. We hope it will make a great additional computer for your family, too. New Chromebooks, for everyone.

Modem vs Router

2012-10-09T10:44:00.002+05:30

When subscribing to an ISP, they would usually provide you with a box that connects to your phone line and to your computer. This box is usually both a router and a modem. A modem is a device that negotiates the connection with your ISP through your telephone line while a router is a device that is used to connect two networks together, in this case your network to your modem.

Traditionally modems were stand alone devices that can be connected straight to your computer or to a router. It connects to the router via the standard RJ45 and with the telephone line via the smaller RJ11. Its job is simply to translate data from one protocol to another since telephone lines do not use the same signaling and transmission methods that are used in computer networks. Because of this, data isn’t being screened by the modem and any potential threat would still go through to your network.

Routers only use RJ45 since it is understood that it would only connect to computer networks. Its job is to examine a data packet and determine where it should go; it chooses the route the data should take, thus the name router. It is in a router where firewalls are implemented in order to screen out potential attacks or threats that might try to gain access to your network.

You should know that modems are the means to connect to the internet and without modems the internet would not exist. Routers on the other hand, are not really essential for internet communication. It is still possible to connect to the internet without routers just like in the old days with internal PCI modems. But you should remember that the main job of the router is to protect you from possible threats and malware, and this shouldn’t be taken very lightly.

Do you Know the Difference Between Tablet and Smartphone..

2012-10-09T08:00:00.000+05:30

Smartphones and tablets are the hottest gadgets nowadays. Even though tablets and smartphones look pretty much the same, there are still major differences between them. The main difference between tablets and smartphones is obviously the size. Tablets are much bigger than smartphones, and the screen size is typically the basis of measurement. Tablets range from models with 7 inch screens, with models around 10 inches being the most popular, and there also models that have even larger screen sizes. Smartphones are much smaller with most models sporting 4 inch screens. It is important for smartphones to be small since majority of people carry them in their pockets, especially men.
There is also a difference when it comes to the applications that you are able to run. Tablets and smartphones typically share the same operating; Android tablets and smartphones, as well as the iPad and the iPhone. But there are applications that only run in tablets and not in smartphones. This is not because of limitations in the processor but usually because of the impracticality of small screens with the app.
When it comes to network connectivity, smartphones trump tablets. Virtually all smartphones have WiFi and 3G connectivity, the latter is basically a given since connecting to a cellular network is a must for smartphones. Tablets have WiFi at the very least for connectivity, but only high-end and pricier models feature 3G connectivity.

Despite having a wide array of uses, the primary function of smartphones is still for communication. Tablets on the other hand are not intended as phone replacements. Although some tablets have the ability to send SMS or do calls, many do not. You can immediately rule out tablets that do not have 3G as the hardware is necessary for this functionality. And even if your tablet allows you to make calls, you would probably have to purchase a Bluetooth headset as it is rather awkward to hold a large tablet to your face.
Smartphones can do the job of a tablet and more. If you are usually on the go, a smartphone is the better choice as you can quickly pull it out or store it when the need arises.

Story:Pencil and Eraser

2012-09-25T19:15:00.001+05:30

Pencil: I'm sorry

Eraser: For what? You didn't do anything wrong.

Pencil: I'm sorry because you get hurt because of me. Whenever I made a mistake, you're always there to erase it. But as you make my mistakes vanish, you lose a part of yourself. You get smaller and smaller each time.

Eraser: That's true. But I don't really mind. You see, I was made to do this. I was made to help you whenever you do something wrong. Even though one day, I know I'll be gone and you'll replace me with a new one, I'm actually happy with my job. So please, stop worrying. I hate seeing you sad.

I found this conversation between the pencil and the eraser very inspirational. Parents are like the eraser whereas their children are the pencil. They're always there for their children, cleaning up their mistakes. Sometimes along the way, they get hurt, and become smaller / older, and eventually pass on. Though their children will eventually find someone new (spouse), but parents are still happy with what they do for their children, and will always hate seeing their precious ones worrying, or sad. All my life, I've been the pencil. And it pains me to see the eraser that is my parents getting smaller and smaller each day. For I know that one day, all that I'm left with would be eraser shavings and memories of what I used to have.

10 must-have Google Chrome add-ons

2012-08-29T23:19:00.002+05:30

Depending on which Web metrics firm you believe, Google Chrome either surpassed Mozilla
Firefox in worldwide browser market share in late 2012, picking up the number two spot behind Microsoft's IE. Either way, it's clear that Chrome's star is rising.Here are 10 more essential add-ons, many exclusive to Chrome, that will please everyone from procrastinators to productivity buffs.

StayFocusd

When it comes to productivity, you are often your own worst enemy. StayFocusd can help. It lets you set a daily time limit for browsing time-wasting websites of your choosing; once your allotted time is up, the sites are blocked until the following day. You may be able to slip Facebook sessions past your boss, but StayFocusd's all-seeing eye can be disabled only by uninstalling the add-on, making this a nearly foolproof way to remain on task

Aviary

Revisionists, rejoice! The Aviary add-on lets you edit images right in your browser without being rerouted to another site or program.

When you're browsing, just right-click an image and choose Edit Image in Aviary from the context menu. Up pops the image in a simple widget that lets you adjust colors, crop, rotate, eliminate red-eye, add silly "stickers" and more, then save it to your desktop.

Session Manager

Never worry about finding websites from a previous browsing session again. Session Manager saves entire browser sessions in their current state, allowing you to revisit a series of websites accessed on a previous date, exactly as they were when you first clicked on them

Chrome to iPhone or Google Chrome to Phone

Running out the door is a lot less stressful when you pair your Android smartphone with Google's Chrome to Phone or your iPhone with myPhoneDesktop's Chrome to iPhone (shown at left). Both send links, images, phone numbers and other important information right to your smartphone when you click on an in-browser button. With push notifications, the ability to set default actions for different data types and multiple handset support, they help streamline your digital life.

Taskforce

Taskforce turns your Gmail inbox into a productivity nerve center for your digital life. The add-on converts emails into tasks, schedules those tasks and shares them with others, even if they don't use Taskforce. And it does all of that without forcing you to leave your inbox

Things to Do

Productivity tools with oodles of features work well for advanced taskmasters. But the rest of us may be better served by simple add-ons that actually encourage us to get things done

AddThis

AddThis is your one-stop shop for all things sharing. Click the in-browser AddThis button and you'll be able to broadcast content to over 300 different Web services. That simple browser button lets you tweet, share or email links without the hassle of switching between pages

FastestChrome

FastestChrome, a Chrome version of the popular FastestFox Firefox extension, is like steroids for your browser. Although it doesn't actually load pages faster, the add-on's numerous features make browsing faster overall. For instance, it automatically loads the next page of a website for minimal interruption while reading, and when you highlight a word or phrase on the page, its definition appears in a pop-up

SpeakIt!

Multitaskers, meet your new best friend. Install SpeakIt!, highlight on-screen text on a non-encrypted Web page and click the SpeakIt! toolbar button to hear the text read aloud to you while you get work done. It's the perfect way to listen to the latest celebrity updates from TMZ while, you know, doing important things. It's also a great add-on for eye-strained Web users in need of relief

Good things come in small packages. With one click, the Up add-on sends users up one level in the currently loaded URL. It'll also display the path list back to the original website, making navigation among multiple URL levels quick and easy.

The Earth on Your Desktop in Real Time!

2012-08-27T10:38:00.000+05:30

Desktop Earth is a wallpaper generator for Windows. It runs whenever you're logged on and updates your wallpaper with an accurate representation of the Earth as it would be seen from space at that precise moment.

Day and night is accurately represented depending on the Sun's overhead position (which depends on both the time of day and the day of the year) and both the snow cover and the foliage changes with the seasons.

Images are created from high-resolution textures (2560x1280) so it's perfect for that QSXGA display.

An image is generated every month to accurately depict snow and foliage changes, and the night view is simply stunning.

If you just want to stick with one view of the earth, there is a huge stash of wallpapers in the install directory that can be used permanently without being connected to the internet or having Desktop Earth installed.

INSTRUCTIONS

After installation DesktopEarth will start automatically and display the following configuration dialog:

This should be pretty self-explanatory, but here are some pointers:

Image Options control basic image parameters such as what the wallpaper is centered on and how to deal with an image that does not match the aspect ratio of the source: add black bars or crop. You can also choose to add clouds to the image - more on this topic a bit later.
Display Options allows you to select between wallpaper styles. The Regular Wallpaper setting should work well for everyone, even in multi-monitor environments. When your destkop's size or shape changes the Earth wallpaper will change with it in a few moments.

Desktop Earth will start automatically every time you log in to Windows. There's a system tray icon that you can use to bring up the configuration dialog again:

This brings us to the final point: clouds. The cloud image bundled with Deskop Earth is (obviously) static, but selecting "Cloud Updates" from the systray menu and enabling automatic updates will retrieve a semi-realtime cloud image from the Internet. Since cloud formations big enough to show up on these images move very slowly, it does not really matter that the images are a few hours out of date.

Dont hope..

2012-08-03T13:49:00.000+05:30

While waiting to pick up a friend at the airport in Portland, Oregon, I had one of those life-changing experiences that you hear other people talk about — the kind that sneaks up on you unexpectedly. This one occurred a mere two feet away from me.

Straining to locate my friend among the passengers deplaning through the jet way, I noticed a man coming toward me carrying two light bags. He stopped right next to me to greet his family.

First he motioned to his youngest son (maybe six years old) as he laid down his bags. They gave each other a long, loving hug. As they separated enough to look in each other’s face, I heard the father say, “It’s so good to see you, son. I missed you so much!” His son smiled somewhat shyly, averted his eyes and replied softly, “Me, too, Dad!”

Then the man stood up, gazed in the eyes of his oldest son (maybe nine or ten) and while cupping his son’s face in his hands said, “You’re already quite the young man. I love you very much, Zach!” They too hugged a most loving, tender hug.

While this was happening, a baby girl (perhaps one or one-and-a-half) was squirming excitedly in her mother’s arms, never once taking her little eyes off the wonderful sight of her returning father. The man said, “Hi, baby girl!” as he gently took the child from her mother. He quickly kissed her face all over and then held her close to his chest while rocking her from side to side. The little girl instantly relaxed and simply laid her head on his shoulder, motionless in pure contentment.

After several moments, he handed his daughter to his oldest son and declared, “I’ve saved the best for last!” and proceeded to give his wife the longest, most passionate kiss I ever remember seeing. He gazed into her eyes for several seconds and then silently mouthed. “I love you so much!” They stared at each other’s eyes, beaming big smiles at one another, while holding both hands.

For an instant they reminded me of newlyweds, but I knew by the age of their kids that they couldn’t possibly be. I puzzled about it for a moment then realized how totally engrossed I was in the wonderful display of unconditional love not more than an arm’s length away from me. I suddenly felt uncomfortable, as if I was invading something sacred, but was amazed to hear my own voice nervously ask, “Wow! How long have you two been married?

“Been together fourteen years total, married twelve of those.” he replied, without breaking his gaze from his lovely wife’s face. “Well then, how long have you been away?” I asked. The man finally turned and looked at me, still beaming his joyous smile. “Two whole days!”

Two days? I was stunned. By the intensity of the greeting, I had assumed he’d been gone for at least several weeks – if not months. I know my expression betrayed me.

I said almost offhandedly, hoping to end my intrusion with some semblance of grace (and to get back to searching for my friend), “I hope my marriage is still that passionate after twelve years!”

The man suddenly stopped smiling.

He looked me straight in the eye, and with forcefulness that burned right into my soul, he told me something that left me a different person. He told me, “Don’t hope, friend… decide!” Then he flashed me his wonderful smile again, shook my hand and said, “God bless!”

Intel sets timeline to develop world's first conflict-free processor

2012-07-24T05:00:00.000+05:30

Intel is preparing to produce the world’s first conflict-free processor by the end of 2013. The revelation comes as part of the company’s recently-released Corporate Responsibility Report 2011 that outlines a number of green efforts though 2020.
Conflict materials are those that are mined in regions that contain armed conflicts or human rights issues – a good example of this is the Democratic Republic of the Congo. According to the Foreign and Commonwealth Office, money earned from the export of minerals from conflict regions is a solid source of funding for armed groups. As you can imagine, this isn’t exactly good PR for tech companies.

Intel has declared intentions to become conflict-free across four key minerals: gold, tantalum, tin and tungsten by the end of 2013. In fact, the company plans to achieve the tantalum goal by the end of this year. This essentially means that next-generation microarchitecture Haswell processors could be the first ever to contain conflict-free materials.
Other environmental goals include a reduction in greenhouse gas emissions and water use per processor manufactured as well as increasing the efficiency of data centers and notebook computers by 25 times through 2020.
There are also plans to build new facilities in Arizona, Costa Rica, China, Israel and Malaysia that would meet LEED Silver Certification in addition to an energy-saving plan that would reduce power consumption by 1.4 billion kWh through 2015. Chipzilla hopes to achieve zero chemical waste to landfill by 2020.

World's third largest spam botnet 'Grum' taken down

2012-07-23T05:00:00.000+05:30

Security researchers announced they’ve dismantled the world's third-largest botnet, known as Grum, which is believed to have been responsible for 18% of the world's spam.
The shutdown was a joint effort between California security firm FireEye, the British-based Spamhaus Project, and the Russian-based Computer Security Incident Response Team known as CERT-GIB who worked together and convinced the companies that hosted Grum’s command and control servers to pull the plug on the operation.
Grum relies on two types of control servers: one to push configuration updates to the infected computers that are part of the botnet and another to tell the botnet what spam emails to send.
Initially researchers from FireEye were able to take down two command and control (CnC) servers hosted in the Netherlands of the second kind.
While this crippled the botnet’s operation, remaining CnC servers hosted in Russia, Panama, and a few in Ukraine that cropped up at the last minute in response to the previous shutdowns could still be used to update the botnet and direct it to new spam template servers.
Fortunately, that didn’t happen and yesterday Grum was dealt its final blow as folks in the worldwide security industry collaborated to apply pressure to local ISPs and domain registrars to shut down the remaining servers.
The researchers said the botnet had been using as many as 120,000 infected "zombie" computers to send out spam each day. More than 20,000 computers are apparently still spewing out junk email, but without the active CnCs they will soon be rendered ineffective.

Google acquires Sparrow

2012-07-22T22:45:00.001+05:30

Email startup Sparrow has been acquired by Google. The company’s CEO Dom Leca announced the news on the company's site and Twitter account, saying that the team behind the popular iOS and Mac email client will be joining the Gmail team to “accomplish a bigger vision”.
Exactly what that new vision entails is unclear. So far the company been entirely Apple-centric, launching in February 2011 as it sought to capitalize on the rather poor Gmail experience offered to iOS users at the time -- an official app didn’t arrive for Apple’s mobile platform until November last year and the spartan email client that ships with the iPhone and iPad left much to be desired for Gmail users. Sparrow became the top paid and top grossing app in less than one day.
According to a statement sent to 9to5Mac, the team behind Sparrow will continue to make their existing apps available and provide support as well as critical updates to our users, but no new features will be added going forward. Apparently they will be busy with new projects at Google instead, which could mean the focus will shift solely to Android, or simply that the Sparrow email client is no more.
Either way it’s bad news for existing users of Sparrow. Financial terms of the deal have not been disclosed.

What Is WiFi?

2012-07-18T12:50:00.000+05:30

If you've been in an airport, coffee shop, library or hotel recently, chances are you've been right in the middle of a wireless network. Many people also use wireless networking, also called WiFi or 802.11 networking, to connect their computers at home, and some cities are trying to use the technology to provide free or low-cost Internet access to residents. In the near future, wireless networking may become so widespread that you can access the Internet just about anywhere at any time, without using wires.

WiFi has a lot of advantages. Wireless networks are easy to set up and inexpensive. They're also unobtrusive -- unless you're on the lookout for a place to use your laptop, you may not even notice when you're in a hotspot. First, let's go over a few WiFi basics.

What Is WiFi?

A wireless network uses radio waves, just like cell phones, televisions and radios do. In fact, communication across a wireless network is a lot like two-way radio communication. Here's what happens:

A computer's wireless adapter translates data into a radio signal and transmits it using an antenna.
A wireless router receives the signal and decodes it. The router sends the information to the Internet using a physical, wired Ethernet connection.

The process also works in reverse, with the router receiving information from the Internet, translating it into a radio signal and sending it to the computer's wireless adapter.

The radios used for WiFi communication are very similar to the radios used for walkie-talkies, cell phones and other devices. They can transmit and receive radio waves, and they can convert 1s and 0s into radio waves and convert the radio waves back into 1s and 0s. But WiFi radios have a few notable differences from other radios:

They transmit at frequencies of 2.4 GHz or 5 GHz. This frequency is considerably higher than the frequencies used for cell phones, walkie-talkies and televisions. The higher frequency allows the signal to carry more data.
They use 802.11 networking standards, which come in several flavors: 802.11a transmits at 5 GHz and can move up to 54 megabits of data per second. It also uses orthogonal frequency-division multiplexing (OFDM), a more efficient coding technique that splits that radio signal into several sub-signals before they reach a receiver.
WiFi radios can transmit on any of three frequency bands. Or, they can "frequency hop" rapidly between the different bands.

WiFi Hotspots

If you want to take advantage of public WiFi hotspots or start a wireless network in your home, the first thing you'll need to do is make sure your computer has the right gear. Most new laptops and many new desktop computers come with built-in wireless transmitters. If your laptop doesn't, you can buy awireless adapter that plugs into the PC card slot or USB port. Desktop computers can use USB adapters, or you can buy an adapter that plugs into the PCI slot inside the computer's case. Many of these adapters can use more than one 802.11 standard.

Mobile broadband..

2012-07-15T12:12:00.000+05:30

"Mobile broadband" is a wireless carrier marketing term for Internet access. Bit rates of broadband support voice and video as well as other data access. Devices that provide mobile broadband to mobile computers include: PC cards also known as PC data card or Connect cards, USB modems, USB sticks often called "dongles", and portable devices with built-in support for mobile broadband (like notebooks, netbooks and Mobile Internet Devices). Notebooks with built-in mobile broadband modules are offered by many laptop manufacturers.
In 2002, the Institute of Electrical and Electronics Engineers (IEEE) established a Mobile Broadband Wireless Access (MBWA) working group. They developed the IEEE 802.20 standard in 2008, with amendments in 2010. Another working group, IEEE 802.16, produced standards adopted in products using the WiMAX trademark.
The global Third Generation Partnership Project (3GPP) family of standards - which includes GSM, EDGE, WCDMA, HSPA and LTE – is the most widespread way to deliver mobile broadband. 3GPP standards are serving about 90 percent of the world’s mobile subscribers.
After mobile broadband subscribers hit 500 million in 2010, at the end of 2011 Ericsson predicted it will be doubled to a billion.
In the United Kingdom, a steering group known as Digital Britain was set up, with the aim of promoting digital telecommunications in October 2008. The conclusion of the steering group was a recommendation that the government took up, namely to have 100% broadband coverage, with a minimum speed of 2Mbps in the United Kingdom by the year 2012. Mobile "broadband" using 3G is now not expected to be able to ensure 2Mbit/s broadband coverage to the more remote areas of the UK as coverage is too poor and contention too high. Another suggestion is Ka Satellite for Rural areas, which may be very cheap by the end of 2010 if Eutelsat's KA-SAT is successfully launched. There is also a smaller Ka Sat in 2010 from Avanti.

What's the Difference?:3G vs. 4G:

2012-06-22T12:58:00.002+05:30

First things first, the "G" stands for a generation of mobile technology, installed in phones and on cellular networks. Each "G" generally requires you to get a new phone, and for networks to make expensive upgrades. The first two were analog cell phones (1G) and digital phones (2G). Then it got complicated.
Third-generation mobile networks, or 3G, came to the U.S. in 2003. With minimum consistent Internet speeds of 144Kbps, they were supposed to bring "mobile broadband." There are now so many varieties of 3G, though, that a "3G" connection can get you Internet speeds anywhere from 400Kbps to more than ten times that.
New generations usually bring new base technologies, more network capacity for more data per user, and the potential for better voice quality, too.
4G phones are supposed to be even faster, but that's not always the case. There are so many technologies called "4G," and so many ways to implement them, that the term is almost meaningless. The International Telecommunications Union, a standards body, tried to issue requirements to call a network 4G but they were ignored by carriers, and eventually the ITU backed down. 4G technologies include HSPA+ 21/42, WiMAX, and LTE (although some consider LTE the only true 4G of that bunch, and some people say none of them are fast enough to qualify.)
There's one rule to follow: Each generation will offer faster Internet speeds than the last, that is, on the same carrier. Sprint's WiMAX 4G is almost always faster than its CDMA 3G. But AT&T's 3G HSPA can be faster than MetroPCS's 4G LTE. You can rely on speeds to move up within your carrier, though.
This confusion is why we run our annual Fastest Mobile Networks story, which tests 3G and 4G networks in 20 cities nationwide. In last year's tests, we generally found that Verizon's 4G LTE network was the fastest, followed by T-Mobile 4G HSPA+, AT&T 4G HSPA+, Sprint 4G WiMAX, MetroPCS 4G LTE, Verizon 3G, and Cricket 3G, with Sprint 3G pulling up the rear. As AT&T and Sprint roll out new LTE networks, we expect them to be competitive with Verizon's LTE speeds.

What is SYNC?

2012-06-17T22:16:00.000+05:30

File synchronization (or syncing) in computing is the process of ensuring that computer files in two or more locations are updated via certain rules.

In one-way file synchronization, also called mirroring, updated files are copied from a 'source' location to one or more 'target' locations, but no files are copied back to the source location.
In two-way file synchronization, updated files are copied in both directions, usually with the purpose of keeping the two locations identical to each other.File synchronization is commonly used for home backups on external hard drives or updating for transport on USB flash drives.
The automatic process prevents copying already identical files and thus can be faster and save much time versus a manual copy, and is less error prone. However this suffers from the limit that the synchronized files must physically fit in the portable storage device. Synchronization software that only keeps a list of files and the changed files eliminates this problem.
Here are some websites allow you to syncing

Windows Live Mesh

With Windows Live Mesh and the Devices website, you can keep up-to-date copies of documents, photos, and other files on all of your computers, whether PC or Mac. Sync your folders to the 5 GB of free storage space you get with SkyDrive, and work your files on the web from any computer. Run programs and browse all the files on your PC from anywhere by connecting remotely. And keep your favorites in Internet Explorer and your Microsoft Office settings up to date on all of your PCs by syncing your program settings.

Sync folders between computers

If you have two or more computers with Windows Live Mesh installed, you can sync folders between them (peer-to-peer). When you sync folders between computers, any changes you make on one computer will be made on the other whenever the computers are online at the same time. The contents of the synced folders are saved on all of the computers, so you can still work on them even when you're not connected to the Internet.

All transfers are encrypted using the Transport Layer Security (TLS) or Secure Sockets Layer (SSL) protocols.

Click the Start button. In the search box, type Mesh, and then, in the list of results, click Windows Live Mesh. Select the folder you want to sync, and then click Sync.

Select the other computers where you want to sync the folder, and then click OK. The folder will be saved in your personal folder on any PCs you selected. (You can get to this folder by clicking your name on the Start menu.) The folder will be saved in your home folder on any Mac you selected.

Price: Free to $100 per year for 100GB; additional $24.99 per year for iTunes Match
iTunes Match basically scans your music and, if it has a match of a song, it gives you license to download or stream that song from its servers at any time, meaning you can delete files from your computer.

Price: Free (10GB) to $19.99 per month (100GB)
It doesn't have a big name, or even a very long one, but CX offers more free storage than any of its competitors: a whopping 10GB! That will be reason enough for many users to snap up an account. CX also has a very elegant online dashboard that I like even more than its downloaded software for both Mac and Windows, which might make it ideal for people who used shared computers frequentlyand can't always install software locally.

Dropbox

Price: Free (2GB) to $19.99 per month (100GB)
Dropbox is ideal for working with files that you want store in a single folder. The Dropbox mantra is, "Put it in the Dropbox folder, and it will sync." However, Dropbox does allow you to set up entire sub-folder structures, if you'd rather, it's just not how the developers envisioned the service in its earliest days and hence is seen as an advanced option. When used as intended and designed, Dropbox is dead simple. There are versions for Windows, Mac, Linux, iOS, Android, and BlackBerry.

SugarSync

Price: Free (5GB) to $14.99 per month (100GB)
File-synchronization service SugarSync offers a generous 5GB cloud storage space with a free account. By far the most intuitive of all the products we've tried, SugarSync is a breeze to use across all major operating systems: Windows, Mac, Linux (in beta), Android, BlackBerry, iOS, Symbian, and Windows Phone. When you install the software on a computer, it adds a right-click function that allows you to quickly mark any file or folder to back up, which is immensely useful.

Syncplicity

Price: Free for 2GB to $15 per month for 50GB
Similar to SafeSync, Syncplicity also touts its strong security measures and puts a price on its syncing service ($15 per month for 50GB), although it does have a free option that's equal to Dropbox's: 2GB. If you use sites such as Picnik, Zoho, Scribd, and iPaper for editing files, Syncplicity might be appealing for its integration with those services.

Apple-MacBook Pro..

2012-06-15T13:17:00.000+05:30

The all-new MacBook Pro changes the entire notebook experience. What you see onscreen is unbelievably sharp. Everything you do is lightning fast. And if you can imagine it, you can create it. Welcome to the future of pro performance.

4x Greater Bandwidth

With sequential read speeds up to 500MBps, all-flash storage is up to four times faster than a traditional hard drive.

Faster than the sum of its parts.

The latest quad-core Intel Core i7 processors help you power through the most complicated technical computing tasks. Next-generation Kepler NVIDIA graphics let you take on the most graphically intense rendering. State-of-the-art I/O like Thunderbolt and USB 3 makes it possible to expand your workspace in a matter of seconds. And at the center of it all is an entirely flash-based architecture that makes everything you do incredibly fast and responsive. Specs like these define a whole new standard for notebook computing.

Now art really does imitate life.

At 5.1 million pixels, the Retina display is the perfect place to view and edit your high-resolution photos. Dot for dot, more of your image can fit on the screen — which makes editing photos far more precise. And with four times the number of pixels than a standard 15-inch MacBook Pro display, you can see fine details and textures like never before. In fact, the Retina display is so sharp, you can tell which photos are in focus just by looking at the thumbnails.

All your photos. In a flash.

With two ultrafast Thunderbolt ports, two USB 3 ports, and an SDXC card slot, you can build a photo studio around this MacBook Pro. Or take it with you and import thousands of RAW images on location — up to five times faster than on a standard MacBook Pro.² Once your photos are on your computer, editing in Aperture is faster and more responsive than on any notebook we’ve ever built. And high-speed flash storage lets you quickly browse large image libraries from internal storage. So you have instant access to any photo in your library.

Edit up to four streams of uncompressed 8-bit 1080p HD video — right from internal storage.

Power on location.

The processor, graphics, and memory inside the all-new MacBook Pro are built around an all-flash architecture — giving you unprecedented mobile video editing capabilities. Super-responsive flash storage delivers up to nine streams of 1080p ProRes (HQ) content for multicam editing in Final Cut Pro X,³ while the latest quad-core processors decode multiple streams of video, and a powerful GPU renders millions of pixels onto the screen. With flash storage that offers up to four times the performance of a traditional hard drive,¹ you can even edit four streams of uncompressed 8-bit 1080p HD video, right from your internal storage.⁴

Having four times the pixels of a traditional display changes how you edit video on a notebook. Especially in Final Cut Pro X. For the first time on a portable computer, you can view your video in pixel-accurate 1080p HD and see your editing workspace onscreen at the same time. And video is so sharp, so clear, and so lifelike, your shots may look even better than you remember.

Work with more pixels per inch.

The all-new MacBook Pro is the ultimate creative design studio. With 2880 by 1800 pixels, the resolution of the Retina display is so high, it rivals the printed page. Combined with reduced glare, higher contrast, and a 178-degree viewing angle, this Retina display is the ideal place to see your work. High-performance graphics and processors let you render images and apply filters with incredible speed. And thanks to flash storage and superfast 1600MHz memory, you can access and edit large-format files much faster than on a traditional notebook.

A powerful notebook for powerful ideas.

The latest quad-core processors and up to 16GB of 1600MHz memory provide an enormous amount of computational power. And the latest GPU technology and the high-resolution Retina display allow you to visualize your data like never before. From 3D molecular modeling and DNA imaging to architectural renderings and structural analysis, the all-new MacBook Pro lets you do things that once were possible only on a desktop computer — anywhere the job takes you.

Internet Protocol (IPv6.)

2012-06-15T12:42:00.000+05:30

   One of the crucial mechanisms powering the Internet got a giant, years-in-the-making overhaul on Wednesday.When say "giant," not kidding. Silly-sounding huge number alert: The Internet's address book grew from "just" 4.3 billion unique addresses to 340 undecillion (that's 340 trillion trillion trillion). That's a growth factor of 79 octillion (billion billion billion).
   If it all goes right, you won't notice a thing. And that's the point.The Internet is running out of addresses, and if nothing were done, you certainly would notice. New devices simply wouldn't be able to connect.
To prevent that from happening, the Internet Society, a global standards-setting organization with headquarters in Geneva, Switzerland; and Reston, Va., has been working for years to launch a new Internet Protocol (IP) standard called IPv6.

IP is a global communications standard used for linking connected devices together. Every networked device -- your PC, smartphone, laptop, tablet and other gizmos -- needs a unique IP address.With IPv6, there are now enough IP combinations for everyone in the world to have a billion billion IP addresses for every second of their life.
That sounds unimaginably vast, but it's necessary, because the number of connected devices is exploding. By 2016, Cisco (CSCO, Fortune 500) predicts there will be three networked devices per person on earth. We're not just talking about your smartphone and tablet; your washing machine, wristwatch and car will be connected too. Each of those connected things needs an IP address.

Then there's all the items that won't necessarily connect to the Internet themselves, but will be communicating with other wired gadgets. Developers are putting chips into eyeglasses, clothes and pill bottles. Each one of those items needs an IP address as well.
The current IP standard, IPv4, was structured like this: xxx.xxx.xxx.xxx, with each "xxx" able to go from 0 to 255. IPv6 expands that so each "x" can be a 0 through 9 or "a" through "f," and it's structured like this: xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx. (Yes, there was an IPv5, but it was a streaming multimedia standard developed in the late 1970s that never really caught on).
The changeover is akin to when the U.S. telephone system handled soaring growth by increasing the digits in each telephone number -- except for one crucial difference. While the entire telephone system was upgraded in the 1990s, the Internet will be upgraded gradually.IPv4 will continue to exist alongside IPv6 for quite some time, just as digital and analog TV were broadcast side-by-side for years.

Most of the major websites and networks are already participating. More than 2,000 websites, including Google (GOOG, Fortune 500), Facebook (FB), Bing, Yahoo (YHOO, Fortune 500), AOL (AOL) and Netflix (NFLX), as well as a number of network operators such as AT&T (T, Fortune 500), Verizon (VZ, Fortune 500), Comcast (CMCSA) and Time Warner Cable (TWC, Fortune 500), have begun enabling IPv6.
But they'll all need to continue to support IPv4 until the entire world upgrades. That will take years.

Facebook App Center..

STORY HIGHLIGHTS

Facebook App Center starting with 600 "high-quality" apps, social network says
While most remain free, developers can offer paid apps for the first time
Move creates more competition with the likes of Apple, Google and Amazon

The Facebook App Center gives users a one-stop shop for Draw Something, Instagram, Pinterest and hundreds of other apps that run on the social-media mega-site.

In all, the center, which began rolling out Friday to users in the United States, will open with about 600 apps available. And, for the first time, Facebook will be offering paid apps as well as free ones from the center.

The center will be available on the Web and on Apple's iOS and Google's Android operating systems.According to Facebook, the center will offer personalized suggestions to users based on their interests and will only include "high-quality apps" based on feedback from people who use them.

"Many developers have been successful with in-app purchases, but to support more types of apps on Facebook.com, we will give developers the option to offer paid apps," Facebook's Adam Brady wrote.

Many of the apps featured in the App Center are already available on Facebook (although the site expects new ones to spring up). But with the App Center, users will be able to browse for new ones instead of randomly discovering them.

The social-media site said the ratings and targeting will help users spend less time weeding through low-quality apps to find the ones they really want.

Facebook makes about 15% of its money through payments in games and other apps, according to filings when the site went public. Zynga, owner of FarmVille, Draw Something and other successful games, is responsible for the majority of those payments. Facebook takes a 30% cut.

Each app will have a detail page that will be found in Web searches and give potential users information about the app.

Windows 8 Features.

2012-06-08T22:50:00.000+05:30

Here's what's new since the Developer Preview. Anyone who's been playing with the Windows 8 Developer Preview will notice quite a few changes, both in content and user interface design. It also introduces some very handy new touch gestures for tablet users. But keyboard and mouse users—Microsoft's bread and butter—haven't been left out either. Here are the changes that stood out among those in this latest pre-release of Microsoft's next big operating system.
1. The Windows Store
Microsoft's answer to Apple's App Store for iOS devices and Macs. In its present form, the store only offers free software. You just need a Microsoft ID such as a Hotmail or Windows Live Messenger account to acquire the Metro-style apps in the store.

You'll also find the addictive game, Cut the Rope in there, along with many other games. Apps are well categorized into groups like Social, Entertainment, Photos, Music & Videos, Books and reference, News, Food, Shopping, and so on. And it's easy to swipe back and forth through them. There's also a Spotlight section, along with tiles for Top Paid, Top Free, New releases, and All Stars.There's a surprising selection for a store that just opened. Since all the current apps are free, I couldn't check out the Trial install capability—something not offered by the iOS App Store.
     Once you hit Install button, the activity dots animate across the screen. Then you'll see a fly-in notification at upper-right telling you that the app was installed. The new app's tile will appear at the end of your Start screen.
2. The Charms
The "Charms"—what Microsoft is calling Windows 8's main system menu icons—have moved from the lower left corner of the screen to the center of the right edge. The mouse point to open them has moved to the opposite point on the screen: Now you have to move the cursor to the top right corner and then down to access the Charms. For touch input, the charms are more accessible, requiring only a swipe out off right edge of the screen.

3. Semantic Zoom
This feature lets you pinch the Windows 8 Metro Start screen to more easily see all your app tiles. Just pinch on the screen, and the tiles will not just shrink, but intelligently resize to remain useful.
4. Running app stack gesture/mouse to top left corner
There's a new way to navigate among running apps. On a touch screen, you swipe a finger in from the left edge of the screen and then back out. This displays a vertical stack of thumbnails for all your running apps. Just touch one of these thumbnails to switch to the app it represents.
5. Smoother transition to Desktop
It's a subtle difference, but in the Developer Preview, the animation displayed when you switched from the Metro user interface to the traditional Windows desktop interface was pretty jarring. It was a showy sliding animation with a zooming out effect.
6. Mouse to move Metro start tiles on Start
There's plenty of new goodness for keyboard and mouse users in Consumer Preview, too. Possibly foremost among these is the ability to move through the Metro Start page tiles by simply nudging the mouse cursor against either edge of the screen.

7. Systemwide Spell checker
Spell checking is the newest of the features Windows 8 apps will be able to take advantage of. The others being Share (to mail, social networks, and so on), and store to SkyDrive's cloud storage. The new spell checker, in typical fashion, places a squiggly red underline under suspected misspelled words, and clicking on this proposes corrections. You also get the Word-like Add to dictionary and Ignore options.

8. No More Start Button, or Is there?

There was an outpouring of lamentation for the dearly departed Windows Start button a few weeks ago, but it's death is only virtual. When a mouse user moves the cursor to the place the Start button has occupied for decades, a new one sprouts up, looking like a mini-thumbnail of the Metro Start screen. Clicking, of course, invokes the Start screen. You can still just start typing to search for an app or document as you could with previous Windows Start buttons. Right clicking this brings up a list of geeky choices like Disk Management, Event Viewer, and Command Prompt. Microsoft (probably rightly) considers right-clicking the sole province of geeks and power users.

9. Close app by dragging down
Another new gesture lets touch users close a running app simply by holding a finger on its window and dragging all the way down to the bottom of the screen.
10. Screen Capture—Windows Key + PrtSC
Now, to create an image file of the screen anywhere in the system, you simple press the Windows key + Print Screen. On a Windows 8 tablet, you can also hold down the Windows button and volume rocker.
11. New Apps—People, Music, Mail, Messaging, SkyDrive
Apps includes with Windows 8 Consumer have been pared down to about a dozen, compared with the over two dozen that came with Developer Preview. The new ones include essentials like mail, photos, weather, finance, Maps, People (for social updates), Calendar, Video, Messaging, Photos, and Music.
12. Picture password
Microsoft has done extensive research on the security of these passwords, even testing whether screen smudges could give trespassers entry, which proved highly unlikely. Statics analysis has also shown that there are in excess of a billion three-gesture combinations.
