What is Team Viewer?
This is basically a computer software package that enables remote access and control, desktop
sharing, file transfers, web conferencing and online meetings among others. It is available for most
of the existing operating systems including Windows OS X, Android, Windows Phone, iOS, Linux
and Windows RT.

As a computer package, this software only requires installation to start using and comes with an
installation procedure. However, there is a Quick Support version that can run without needing
installation. The Application is free for both businesses and non-commercial users although there
is a premium version with more features and efficiencies for corporate application. After installing
the software, which is quite simple to achieve, it automatically generates a partner ID and
password. User-defined passwords can also be used if desired. Installing Team Viewer requires
administration access although anyone can use it once installed.

In order to control remote computers through this software, you will need the IDs of those
computers. Browsers can also be used to access remote computers by simply logging in and
entering their IDs. Internet connectivity and user identities are all needed to remotely access and
control other computers and servers. One can only control computers that have the package
installed in them.

Benefits of the software
The advantages of a remote control application that actually works are quite straightforward and
easy to illustrate. For businesses and corporate establishments, this provides a platform to boost
efficiency in information flow, communication and file sharing. Online meetings and conferences
can be quickly arranged between select groups.

Remote access allows authentication, verification, confirmation, signing among other routine
administration and operation tasks to be done from anywhere. While work from home and mobile
technology is not new, team viewer allows users to quickly access office and remote computers
and/or servers as if they were in front of them. The benefits of this access together with capabilities
of desktop sharing and file transfer are enough reasons for the growing use of team viewer and
remote control technologies.

Download Accelerator Plus

Download Accelerator Plus is a tool that helps you speed up your internet downloads by searching servers on the internet to
find the file, or files that you're download. By locating and requesting it from multiple sources at the same time, it can find
the quickest route from its location to your computer's hard drive, landing it much quicker than if it was downloaded from a
single server
This works best when used to look for files that may be commonly available in multiple locations - such as anti-virus
programs, operating system utilities and other executable files that have been made available by their creators. In addition
to speeding up your downloads, Download Accelerator Plus comes with a built-in FTP program that allows you to access,
download and upload files stored on a web server, and a Private Disk function allows you keep your downloads away from
prying eyes

JDownloader 2 BETA

JDownloader2 is the sequel to the popular file downloader JDownloader. Like others on our list, the program can download
files from regular websites, but JDownloader2 stands out for its ability to easily download files from one-click hosts - such as
Rapidshare, MediaFire, Uploaded and NetLoad
Some download managers don't allow this due to incompatibility with the file formats that one-click hosts use, but
JDownloader2 runs into no such problems as it supports the Rapidshare Downloader Format (RSDF), Cryptload Container
Format (CCF) and Download Link Container (DLC) formats
Other handy extras featured in the program include automatic captcha recognition, allowing you to bypass the common (and
irritating) security mechanism, and you can even set up your downloads workflow to automatically move downloaded files
into various folders based on their filename, allowing you to keep organised with minimal effort. Note that you'll need to
.download Java Runtime to get it to work, and the program is still BETA, so bear in mind that it's not the finished product

Free Download Manager

Torrents have something of a reputation when it comes to illegal content, with owners of website
such as The Pirate Bay appearing in headlines for being commanded to the dock for allowing its
users to share copyrighted content. But there are numerous legitimate reasons to use torrents
too, and if you're looking to get involved, Free Download Manger combines the best bits of
regular download managers with torrent downloading programs.

Free Download Manager allows you to start downloads directly from the BitTorrent network or by
clicking on torrents hosted on other sites, in addition to being able to download files over the
regular HTTP, HTTPS and FTP protocols. The program's makers claim they have managed to
increase the tool's speed by up to 600% in the most recent version, which now has the ability to
continue previously cancelled downloads. With a slew of other features including the ability to
convert audio and video into different file formats, Free Download Manager aims to be a one-stop

shop for downloading a multitude of files from a wide range of online locations.

YouTube Downloader

YouTube Downloader is a hassle-free way of ripping YouTube videos to your hard disk drive, with
the option to convert files into multiple different formats. It may have YouTube in its name, but it
also works with a multitude of other video websites - from DailyMotion to Facebook.

The use of a tool like Free YouTube Downloader is necessary as many video websites stream video
in the Flash format, which tends not to be compatible with smartphones, tablets and other
devices. To save time, you can select from a variety of video formats - including AVI, MP4 and
WVM - before pasting in a YouTube URL to automatically convert the file after it's downloaded.

Freemake Video Downloader

Freemake Video Downloader can download videos from a range of websites before converting
them into different file formats. If you're running Firefox, you can even grab a plug-in that allows
you to download any video from YouTube with a single click, which is useful for archiving your
own video collection to hard disk or quickly grabbing copyright-free content from other users'

The program uses Freemake's own video conversion technology that powers its Freemake Video
Converter, allowing you to convert files into formats including MP4, WebM, FLV, MP4 and 3GP.
Aside from the basic conversion options, there's a whole heap of additional features - from
allowing you to download - from social media sites such as Yandex, Facebook, Nicovideo and
VKontakte - and you can set it to download through a proxy server and even filter adult content

Long Live Your
Laptop Battery!

Laptop batteries are like people--eventually and inevitably, they die. And like people, they don't obey
Moore's Law--You can't expect next year's batteries to last twice as long as this year's. Battery
technology may improve a bit over time (after all, there's plenty of financial incentive for better
batteries), but, while interesting possibilities may pop up, don't expect major battery breakthroughs
in the near future.

Although your battery will eventually die, proper care can put off the inevitable. Here's how to keep
your laptop battery working for as long as possible. With luck, it could last until you need to replace
that aging notebook (perhaps with a laptop having a longer battery life)

Don't Run It Down to Empty
Despite what our screen shows, most laptops probably won't allow you to set the critical battery level
at 0 percent--and you shouldn't try.
Squeezing every drop of juice out of a lithium ion battery (the type used in today's laptops) strains
and weakens it. Doing this once or twice won't kill the battery, but the cumulative effect of frequently
emptying your battery will shorten its lifespan. (There's actually an exception to this rule--a
circumstance where you should run down the battery all the way. I'll get to that later)

The good news: You probably can't run down the
battery, anyway--at least not without going to a lot of
trouble to do so. Most modern laptops are designed
to shut down before the battery is empty. In fact,
Vista and Windows 7 come with a setting for just this
purpose. To see it, click Start, type power, and select
Power Options. Click any one of the Change plan
settings links, then the Change advanced power
settings link. In the resulting dialog box, scroll down
to and expand the Battery option. Then expand
Critical battery level. The setting will probably be
about 5 percent, which is a good place to leave it. XP
has no such native setting, although your laptop may
have a vendor-supplied tool that does the same job.

Keep It Cool

Heat breaks down the battery, and reduces its overall life.

When you use your laptop, make sure the vents are unblocked. Never work with the laptop on pillows or cushions. If
possible, put it on a raised stand that allows for plenty of airflow.

Also, clean the vents every so often with a can of compressed air. You can buy this for a few dollars at any computer
store. Be sure to follow the directions on the can, and do this only when the notebook is off.

Give It a Rest

If you're going to be working exclusively on AC power for a week or more, remove the battery first.

Otherwise, you'll be wearing out the battery--constantly charging and discharging it--at a time when you don't need to
use it at all. You're also heating it up (see "Keep It Cool," above)

You don't want it too empty when you take it out. An unused battery loses power over time, and you don't want all
the power to drain away, so remove it when it's at least half-charged.

Never remove the battery while the computer is on, or even in standby or sleep mode; doing so will crash your system
and possibly damage your hardware. Even inserting a battery into a running laptop can damage the system. So only
remove or reinsert the battery when the laptop is completely off or hibernating.

If you've never removed your laptop's battery and don't know how, check your documentation. (If you don't have it,
you can probably find it online.) The instructions generally involve turning the laptop upside-down and holding down a
button while you slide out the battery.

Some people recommend you store it in the refrigerator, inside a plastic bag. While you should keep a battery cool,
the last thing you want is a wet battery, and condensation is a real danger in the fridge. Instead, store it in a dry place
at room temperature. A filing cabinet works fine.

You don't want the battery to go too long without exercise or let it empty out entirely. If you go without the battery
for more than two months, put it in the PC and use it for a few hours, then remove it again.

Also, before you take the laptop on the road, reinsert the battery and let it charge for a few hours before unplugging
the machine. Allow the battery time to get a full charge before you remove the AC power.

New Technology Uses
Robots to Write

Are you ready for your daily sign that robots will become our overlords sooner rather than later? Good,
because researchers at Penn State University have developed a new technology that helps faculty
members create entire textbooks with the help of robots.

The new program is called BBookX, and it uses open online resources to help the user create a wide
variety of media, from study guides to textbooks, in a new genre Penn State is calling "the bionic book."
Users create the material by assigning each chapter of a digital table of contents text or related
keywords or keyphrases that they'd like to see reflected in the information. BBookX then uses matching
algorithms to return text, which users can keep or combine with text of their own.

BBookX seems like it could have many benefits for both faculty and students. Faculty can use the
program to more easily tailor their course materials to their exact curricula and also update them as
things change and new information becomes available from year to year or even while the class is in
session. These textbooks can also be distributed for free, which could help alleviate some of the cost of
attending college for students.

"In any rapidly changing field, such as information sciences and technology and computer science, it's
important that books stay up to date," C. Lee Giles, the David Reese Professor in the university's College
of Information Sciences and Technology who helped build the system, said in a press release. "I wanted
an easy, inexpensive way for faculty and students to have access to the latest knowledge and

Over time, BBookX is designed to apply choices made by professors after they review the textbooks
made by the program to improve the book in each iteration, similar to how Netflix suggests titles for
users to watch based on what they have previously viewed, Penn State's director of education
technology services Kyle Bowen told the Philadelphia Inquirer.

How to recover files
after OS crashed


For this recovery I’ll be using a Ubuntu CD (Linux OS). Also, you can create a bootable Ubuntu USB flash drive. Don’t
worry, you don’t have to be a Linux guru for that. The Linux interface will be very similar to Windows OS.
You need another working computer to download and create a bootable CD or USB drive.

1. Download the latest version of Ubuntu OS here. When you click on the download button you’ll start downloading
an ISO image2 .

2. .Burn this ISO image on a CD or create a bootable USB stick. It’s explained on the same download page, just
scroll a little bit down .

3. .3Find the target drive where you going to save recovered files. You can use an external hard drive or USB flash
drive. The target drive can be formatted with any common Windows file system: FAT, FAT32, NTFS.


Boot your laptop from the Ubuntu CD or USB.

If the computer keeps trying to boot from the internal hard drive, you’ll have to enter the BIOS setup menu and change
the boot order. Set your CD/DVD drive or USB stick as first device in the boot order. Safe changes and restart the

From my experience, Ubuntu OS works fine with most laptop and desktop PC hardware and you shouldn’t have any
problem booting it to the desktop. It may not work if your computer hardware is too new.

The computer will start booting from the CD or USB stick.
Now read carefully!

After some time a welcome screen will pop up. On this screen you can choose your language and choose between two
options: Try Ubuntu and Install Ubuntu.
Select Try Ubuntu. The Linux OS will run directly from the CD or USB stick without changing any files on the hard drive.

Ubuntu OS will continue loading and after a while you’ll boot to the desktop, as it shown on the following picture.

In order to access the internal hard drive, you click on Places in the top toolbar. You should see your internal hard drive in
the drop down menu under the Computer.

When you click on the internal hard drive a new window will open up. In this window you’ll see all files located on the hard

Now plug in your target drive into the computer.
Another window will pop up. In this window you’ll see files located on the external drive. In my case I have no files on the
external drive, that’s why the window is empty.
You can move windows same way you do it in Windows OS. Arrange both windows as you like.

Finally, drag and drop needed files from the internal hard drive to the external drive.
After the transfer is done, you can unplug the external drive and use it on any other computer.

Best free recovery software:
top programs to get your
deleted files back

Recuva Free

Conveniently available in a portable version, Recuva Free is very easy to use. A wizard asks you what type of files
you're looking for, and where to search, then scans your system at speed (FAT, exFAT and NTFS file systems are
Any files found are listed (with previews for images), and you can restore anything you need in a couple of clicks.
Running the program in Advanced Mode provides more options, though, like a Deep Scan (much slower, but
recovers more files), the ability to locate files containing particular text, and even an option to securely wipe files
containing sensitive information, ensuring that no-one else will be able to undelete them.
Whatever mode you're using, Recuva is an excellent recovery tool, effective and very easy to use.

Undelete 360

Undelete 360 is the free version of a commercial product, and so leaves out some useful features (file filtering,
previews and so on). These still appear in the interface, though, and suggest you upgrade if you ever click on
them, which can be annoying.
There are no restrictions on the amount or size of the files you can recover, though, and otherwise the program is
very simple to use: point it at a drive, it'll scan for deleted files, then you can view particular file types (JPGs,
PDFs, videos and more) by choosing them from a tree.

Scanning speed isn't great, but Undelete 360 can recover files that other programs miss , and so it's definitely
worth considering.

MiniTool Partition Recovery

Standard undelete programs are perfect for recovering a few files, but if you've lost an entire partition then you'll
probably benefit from a specialist application like MiniTool Partition Recovery.
The free (for personal use) program has a wizard-based interface which makes it very straightforward to use.
Point MiniTool Partition Recovery at the problem drive, specify the area to be searched, and it'll scan for the
missing partition. A report will let you know what the program has found, and you can recover the partition in a
few seconds.
You don't get a bootable recovery disc here, so if your system partition is damaged then MiniTool Partition
Recovery won't help you very much. Otherwise, though, it provides a quick and easy way to locate and restore
lost partitions.

Wise Data Recovery

It's hard to imagine how any undelete tool could be simpler than Wise Data Recovery.
There are no menus, no complicated options or dialog boxes: all you do is choose a drive, click Scan, and wait as
the program locates any deleted files. Select what you need, click Recover, and that's just about it.
Wise Data Recovery doesn't seem to work with FAT-based drives, though, recovering nothing from our test USB
drive. It's only free for personal use, too. But if you just need something quick and easy to recover files from NTFS
drives then it should probably be on your shortlist.



We love our smartphones when we’re on the go, but when we get back home on our PCs or laptops it’s a pain to
have to juggle between our phones and our computers. However, it doesn’t have to be this way. If you want to be
able to access and manage your Android smartphone from anywhere with Wi-Fi, you should download AirDroid.

AirDroid is our favorite tool for remotely accessing your smartphone. The app, which is free and available on the
Google Play Store, uses your local Wi-Fi network to seamlessly connect your Android device to your PC or Mac.
Once connected, you can interact with your phone from a Web browser or desktop widget, which gives you
hardware information, battery life, and even access to your calls and messaging. It’s like a personalized link to
your phone and all it has to offer. The best part is that it’s so easy to do. AirDroid doesn’t require any proprietary
cables, subscription deals, or funky port forwarding. All you need is a wireless network, the AirDroid app, and a
fairly modern computer.

Securing Your Wireless Network

Understand How a Wireless Network Works

Going wireless generally requires connecting an internet "access point" – like a cable or DSL modem – to a wireless
router, which sends a signal through the air, sometimes as far as several hundred feet. Any device within range can
pull the signal from the air and access the internet.

Unless you take certain precautions, anyone nearby can use your network. That means your neighbors – or any
hacker nearby – could "piggyback" on your network or access information on your device. If an unauthorized person
uses your network to commit crime or send spam, the activity could be traced back to your account.

Use Encryption on Your Wireless Network

Once you go wireless, you should encrypt the information you send over your wireless network, so that nearby
attackers can’t eavesdrop on these communications. Encryption scrambles the information you send into a code so
that it’s not accessible to others. Using encryption is the most effective way to secure your network from intruders.

Two main types of encryption are available for this purpose: Wi-Fi Protected Access (WPA) and Wired Equivalent
Privacy (WEP). Your computer, router, and other equipment must use the same encryption. WPA2 is strongest; use it
if you have a choice. It should protect you against most hackers. Some older routers use only WEP encryption, which
likely won’t protect you from some common hacking programs. Consider buying a new router with WPA2 capability.

Wireless routers often come with the encryption feature turned off. You must turn it on. The directions that come
with your router should explain how. If they don't, check the company’s website.

Limit Access to Your Network

Allow only specific devices to access your wireless network. Every device that is able to communicate with a
network is assigned a unique Media Access Control (MAC) address. Wireless routers usually have a mechanism to
allow only devices with particular MAC addresses to access to the network. Some hackers have mimicked MAC
addresses, so don't rely on this step alone.

Protect Your Network during Mobile Access

Apps now allow you to access your home network from a mobile device. Before you do, be sure that some security
features are in place.

Use a strong password on any app that accesses your network. Log out of the app when you’re not using it. That
way, no one else can access the app if your phone is lost or stolen.

Password protect your phone or other mobile device. Even if your app has a strong password, it’s best to protect
your device with one, too.
