Best Gadget 2014

                  Since five years facebook started its changes to become world best social network.After Google+ is on the race facebook has been changed in many ways.Timline is the most  outstanding change in facebook.Today I'm going to tell you about the latest Facebook's  news feed.
The News Feed has been the way we suck information from our friends, frenemies, exes, and coworkers, since 2006. It's mutated since then—complicating and simplifying itself—as Facebook experiments with better ways to show you new statuses, photos, and links. Today's renovation is no different: another way of funneling social info into your brain. But unlike past attempts, it's bigger (truly, wider), brighter, and overall more eye-strangling. It's full of news. It's full of sections. It's like, according to Zuck, "a newspaper." Those old things.
It's visual progress, for sure—Facebook has done great work sweeping away a lot of what developers call "chrome" (buttons, scrollbars, navigational detritus). What's left is the stuff you ostensibly care about. And that stuff looks swell, making the web version of Facebook match the mobile version almost perfectly—all of the clarity and none of the cramp, it appears. All the crap and button mulch that's festered across the sides of Facebook is now swept into one clean sidebar, just like your smartphone app.

Take photo albums—they'll be bigger, now, with more thumbnails giving you an easier at-a-glance sense of what your friends actually did, and where.



When a friend (or local business, ahem) pops up on your new feed, you'll get more information about them, too, pulling over their entire Timeline badge, with all its horizontal lushness.
Plus their location, of course—if they chose to share it.
The new News Feed realizes it's become filled with high-res photos, videos, music, apps—a million things that make plain on text statuses look quaint. And so it adapts, a la Timeline, with a new look that's supposed to fill up your screen and aim straight at dazzling your eyes. It's the same old dumb photos, sure, but they're given a premium cosmetic treatment
A shared link like the one up top—be it a Gizmodo post or a local obit—will spring onto the page with a bigger preview than we've ever had before, and consolidated comments from all the rest of your friends who've shared it too. This cuts way back on sharing sprawl, and hell, just looks pleasant. This same consolidation will start to think for you, too—the stories (and people) you've commented on and shared dirt about before will give Facebook juice to suggest stories to you, right in the feed. This means Facebook will talk directly to you via News Feed, as opposed to it being purely a river of friend blurbs and advertisements. We'll have to see just how smart (and intrusive) these friendly reminders are.
This sounds like a lot. It is a lot. And so Facebook is splitting up the feed into subcategories—Music, Photos, Games, Friends—so that you're not suffocated with information. Or at least suffocated at a slower, more comfortable rate
Music, for instance, will give you blips about what songs your pals are listening to on Spotify, along with news from the artists you follow. Looking good, JT, but I'm hoping for a Suit & Tie Remix. And if you want news that's just from people you don't know—Oprah, The-Dream, Pepsi, whatever—you can filter that all into its own silo, too. This screams Twitter, only burst way out of the 140-character fence.

Of course, that's not why we go to Facebook, unless we're advertising drones. We go for our friends. Or a small subset of them. So there's a Close Friends feed, too, which eschews all the celebs and local businesses, and just brings in your roommate and boyfriend, et. al. Which is nice! But this is going to mean a lot more clicking, rather than just having everything that everyone does all the time thrown into one big bin.
It begins rolling out today—slowly, like everything Facebook debuts. So keep refreshing, and start taking photos worth seeing large.

Google recently started rolling out an Android 4.1.2 software update for the Google Nexus 7 tablet and some other devices including the Galaxy Nexus smartphone. The update lets you view the home screen in landscape orientation on 7 inch tablets, and includes performance and stability improvements.

But there’s one thing you might want to know before installing the update — you’ll lose root access or any custom recovery you may have installed when you upgrade from Android 4.1.1 to Android 4.1.2 using the over-the-air update.

If you want to keep root access though, there’s an app for that.

These instructions will walk you through the process of updating a Nexus 7 tablet from Android 4.1.1 to Android 4.1.2 while keeping root access. Note that the process may be different for other devices — and this doesn’t apply at all if you’re running a custom ROM such as CyanogenMod 10.

If you have a rooted phone or tablet, all you need to do is install and run OTA RootKeeper before installing the operating system updated.

OTA RunKeeper is available as a free download from the Play Store. The first time you run the app, you should see a pop-up asking if you want to grant it root permissions. Tap the yes button.

Then tap the big button in the center of the screen that says “Protect Root.” Once you’ve done that, the box that says “Protected su copy available” should be checked.

After that’s done, it should be safe to go ahead and install the Android 4.1.2 update. Note that it will still kill your root privileges and overwrite ClockworkMod or TWRP recovery with the stock recovery — but as long as you’ve protected your root, you’ll be able to restore root access with a tap of a button.

If you see a notification alerting you that an update is available, just tape the notification and it will take you to the updater.

If there’s no notification, try going to your settings menu, scroll down and select the “About” option near the bottom of the screen, and then choose “System updates.”

From there you should see a message letting you know what the update does (sort of), and asking if you want to restart your tablet and install the new software. You can also check for updates if there’s not one waiting for you.

Or you can download Android 4.1.2 for the Google Nexus 7 directly from the Google servers and install it using TWRP or ClockworkMod if all else fails.

Once you choose the reboot and install option, it should take about 5 to 10 minutes for your device to install the update and reboot into Android 4.1.2.

When that’s done, you won’t have root access anymore — until you fire up OTA RootKeeper again and this time choose the option to ”Restore Root” rather than protect it.

That’s it. You should now have root access again and be able to use apps that require root permissions including Titanium Backup or root file explorers.

A custom recovery utility makes it easy to flash (install) software updates, make a complete backup of your system, or make other changes in a pre-boot environment.

Once your tablet is rooted, the simplest way to install a custom recovery is to install the free GooManager app from the Play Store, open the menu, and choose the option to “install OpenScript Recovery.”

That will download and install the TWRP custom recovery on your tablet. You can boot into it at any time by opening the GooManager app again and choosing the “Reboot Recovery” option.
