NOW AIRDROID 2 IS AVAILABLE WITH REMOTE CONNECTION OVER WEB & ANTI-THEFT FEATURES

In one of my blogs, I had mentioned about the features of Airdroid. That Airdroid users can wirelessly access manage and control almost all aspects of their smartphones and tablets from their favorite web browser. Airdroid is the best and had almost all the features, so that one can easily use all the applications of their smartphones and tablets through web browser. A few days ago, the developers announced an invite-only beta of the latest version of Airdroid i.e. Airdroid 2.
 
                                        
This Airdroid 2 comes with the ‘Remote Connection Mode’ that allows users to access their devices contents and features over the internet from anywhere in the world in addition to the existing Wi-Fi connection mode. So this Airdroid 2 eliminates the limitation of Airdroid that computer and mobile device should be on the same Wi-Fi network. Along with this, one more feature is added that it also brings remote camera access and a ‘Find Phone’ anti-theft feature.

The biggest feature i.e. the Remote Connection Mode grants the users to access all the Airdroid features from two different Wi-Fi networks. Like you are somewhere else connected to that particular Wi-Fi network and your device at home connected to your home Wi-Fi network and still you can access it through your Airdroid 2.
To use this Remote Connection mode, you will need a valid account to pair with the web and mobile clients together. As of, still now The Remote Connection mode allows transferring of data up to 20 MB in size, but it will allot 1GB of total data usage. Now to navigate through this the user has to log in to the app through a new domain http://v2.airdroid.com/ instead of web.airdroid.com or you may enter the Ip addresses on the Airdroid mobile app into your browsers URL bar. If you have the device with you, you can simply scan the QR code shown on the website to log in. You also can sign up for a new account using your Facebook, twitter, Google account. And once you are connected all is yours, you can perform the whole bunch supported tasks, that all remotely over the internet. You can stream your music and videos, view your gallery photos, manage all your phone logs, view contacts and messages, install apps etc.

Airdroid also now supports a new camera tool that can be used to remotely snapshots from your device’s camera. Once you click on the camera icon tool in your browser, the camera on your device will automatically get started and you are ready to capture live images with all the other options of zoom, pause, rotate. The images captured will be stored to Downloads files of your computer system.
One more feature is Find Phone which helps you to instantly track your Android device location on the map if you find tough looking after your mobile phone. Even if the device loses the internet access or get powers off, still you can see its last registered location. It has also some more features such as sounding the alarm, sending the text messages and remotely locking and wiping the device itself.
As the latest version is currently in beta, you can expect some features to be non-functional at this moment. But soon this will get completely functional with its final version. Airdroid soon will become the best remote device management tool for Android.

Install Packages from Non-Admin Account in Linux Distro



In my last blog “Add user account to root in Ubuntu”, I had written about how we can add or give all root access to any account. Now in this blog I will explain you that how to give only installation access to any Non-Admin account. After giving this access to non-admin account, the user of this account can install as well as remove any packages to and from Non-Admin account.
This is one of most important trick for those Companies and Organization whose Admin is not able to install and removes each packages from every PC’s of each employee.
To use gedit you have to do following:

Open the Terminal and type:

       sudo gedit /etc/sudoers

 
If you want to use vim you can simply enter the following into the Terminal:

        sudo visudo

When you used the “sudo visudo” command in terminal the “sudoers” file is open in terminal with vim editor.
   
Once you have the sudoers file open, scroll down to the line:
   
         root   ALL = (ALL)ALL
After this, on next line of above statement writes following configuration,
         UserName ALL=NOPASSWD : /usr/bin/apt-get , /usr/bin/aptitude
You can change username with your non-Admin account name, save the sudoers file and logout from root account and try to install packages from non-Admin account.

BIOS SAYS “NO”, THEN BOOT WITH USB



We always get a trusty bootable USB flash drive with us to solve computer problems, but what if a PCs BIOS wont let us boot from USB?  There is a way which will help you to make use of CD to boot from USB drive.

 Fig1: Boot menu

This boot menu, like many created before USB drives became cheap and common place does not include an option to boot from a USB drive. A piece of free-ware called PLoP Boot Manager solves this problem, offering an image that can burned to a CD or put on a floppy disk, and enables you to boot to a variety of devices, including USB drives.
Put PLoP on a CD
PLoP comes as a zip file, which includes a variety of files. To put PLoP on a CD, you will need either plpbt.iso or plpbtnoemul.iso from that zip file. Either disc image should work on most computers, though if in doubt plpbtnoemul.iso should workeverywhere,according to the read-me included with PLoP Boot Manager.
Put PLoP on a Floppy Disk
If your computer is old enough to still have a floppy drive, then you will need to put the contents of the plpbt.img image file found in PLoPs zip file on a floppy disk. To do this, well use a free-ware utility called Raw-write for Windows.

Booting PLoP Boot Manager
To boot PLoP, you will need to have your CD or floppy drive boot with higher precedence than your hard drive. In many cases, especially with floppy disks, this is done by default. If the CD or floppy drive is not set to boot first, then you will need to access your BIOSs boot menu, or the setup menu. The exact steps to do this vary depending on your BIOSto get a detailed description of the process, search for your motherboards manual. In general, however, as the computer boots up, some important keyboard strokes are noted somewhere prominent on the screen. In our case, they are at the bottom of the screen.




Fig3: VMware screen

Press Escape to bring up the Boot Menu. Previously, we burned a CD with PLoP Boot Manager on it, so we will select the CD-ROM Drive option and hit Enter.

 Fig4: Boot menu


If your BIOS do not have a Boot Menu, then you will need to access the Setup menu and change the boot order to give the floppy disk or CD-ROM Drive higher precedence than the hard drive. Usually this setting is found in theBootorAdvancedsection of the Setup menu.

If done correctly, PLoP Boot Manager will load up, giving a number of boot options.

 Fig6: Boot options

Highlight USB and press Enter.


                                                               Fig7: USB menu

PLoP begins loading from the USB drive.Despite our BIOS not having the option, were now booting using the USB drive, which in our case holds an Ubuntu Live CD!

This is awesome way to get your PC to boot from a USB, provided your computer still has a floppy drive.
