iPhone 6 Plus full Specification and Reviews

I know this is not the proper place to post this, but i can't sit still without blogging. :p

Well folks, the time for wild rumors reports is finally over - Apple CEO Tim Cook just officially revealed the new iPhone 6 Plus and its 5.5-inch screen in Cupertino alongside a long-rumored (and handier) 4.7-inch model.

Apple wants to give all those other pocket-stretching phablets out there a run for their metaphorical money. The company's live press event still going along but here's what we can get you so far.

 

A SMALL BRIEF :

• Spacious 5.5-inch 1080p Retina Display HD riding up front - to hear Apple's Phil Schiller tell it, it's SRGB- accurate, has an ultra thin back light, photo-aligned IPS liquid crystals, an improved polarize r, and ion-strengthened glass. More importantly (and at long last!), the screen runs at 1080p.

• Dramatically thinner than the iPhones that came before it (the Plus comes in at 7.1mm thick, and the angular edges of the 5s have given way to a smoother, rounder look in line with the company's most recent batch of iPads.

• Apple's snappy new 64-bit A8 chipset - Schiller says it's 50 percent more energy efficient  than the the A7 that graced earlier models, and about 25 percent more powerful to boot.

• Speaking of power, you'll be able to squeeze 16 hours of standby time out of the 6 Plus, 14 hours of continual video playback and or a full 24 hours of 3G talk time out of the non-removable battery.

• Mobile photographers (which is really everyone these days, right?) may be a little bummed to see that the 6 Plus has an 8-megapixel iSight camera and an f/2.2 aperture lens paired with the same True Tone flash as in the 5s.  

• Improved face detection and a new Best Shot mode. Extra bonus for Plus owners: you get optical image stabilization, so you can lord your crisper shots over everyone else when it launches.

• Shoot 1080p video at either 30 or 60 frames per second, and slow motion video has gotten even slower: think a whopping 240 frames per second.   

• The front-facing camera has been updated with a sensor that's even greedier for photons, perfect for all those well-lit "LOOK I HAVE A NEW IPHONE" selfies you'll probably snap.

• Perhaps the biggest is the inclusion of a two-paned landscape mode which makes the whole thing feel a little more like a tiny iPad than an up scaled iPhone. If you give the TouchID button (yeah, you're not escaping those sensors), you'll also invoke a one-handed mode that moves everything down to the lower half of the display for easy access -- great if you've got some short thumbs.

• Apple has done away with the 32GB model entirely and added a 128GB model to the mix too in case you've got a few decades of movies that need to go with you everywhere.

How to Reset password in Ubuntu ??

There are many reasons you might want to reset a password:

• Someone gave you a computer with Ubuntu installed on it but not the password for the user account.
• You just installed Ubuntu and forgot what password you selected during the installation process.
• You have too many passwords in your life and can't keep track of them all.
• Or you might want to hack in your Friends System.

Well, this tutorial will help you reset your Ubuntu user account password, regardless of what reason you have for resetting it.

First, you have to reboot into recovery mode.

If you have a single-boot (Ubuntu is the only operating system on your computer), to get the boot menu to show, you have to hold down the Shift key during bootup.

If you have a dual-boot (Ubuntu is installed next to Windows, another Linux operating system, or Mac OS X; and you choose at boot time which operating system to boot into), the boot menu should appear without the need to hold down the Shift key. 

From the boot menu, select recovery mode, which is usually the second boot option.  

 

After you select recovery mode and wait for all the boot-up processes to finish, you'll be presented with a few options. In this case, you want the Drop to root shell prompt option so press the Down arrow to get to that option, and then press Enter to select it.

The root account is the ultimate administrator and can do anything to the Ubuntu installation (including erase it), so please be careful with what commands you enter in the root terminal.

In recent versions of Ubuntu, the filesystem is mounted as read-only, so you need to enter the follow command to get it to remount as read-write, which will allow you to make changes:

 #mount -o rw,remount /

If you have forgotten your username as well, type  

#ls /home

That's a lowercase L, by the way, not a capital i, in ls. You should then see a list of the users on your Ubuntu installation. In this case, I'm going to reset Susan Brownmiller's password.

To reset the password, type 

#passwd username

where username is the username you want to reset. In this case, I want to reset Susan's password, so I type  

#passwd susan

You'll then be prompted for a new password. When you type the password you will get no visual response acknowledging your typing. Your password is still being accepted. Just type the password and hit Enter when you're done. You'll be prompted to retype the password. Do so and hit Enter again.

Now the password should be reset. Type 

#exit

to return to the recovery menu.  

 After you get back to the recovery menu, select resume normal boot, and use Ubuntu as you normally would—only this time, you actually know the password! 

Note:
Some people get freaked out about having recovery mode logging you in as root. For more information, read Recovery mode makes me root user. Isn't that a security risk?
