All about Backups

Backups are a crucial part of our digital lives, yet they don't always get the love they deserve. Keeping backups is sometimes confusing, thanks partly to the jargon — should I have "differential" backups or is a "full system image" a better way? To address questions like these, this article sheds light on all aspects of backups, from its basic definition, to information that can help you perform the kind of backups you need.
Backing up data is the process of making a copy (or more) of our data files—documents, spreadsheets, presentations, e-books, movies, music, browser bookmarks, settings, installed programs—almost everything. Fundamentally, the questions are: What to backup?When to backup? Where to backup? What type of backups to perform? Do you need more than one backup? Types of backups The simplest way to back anything up is to just dump the files onto a CD, DVD or USB drive. Such kinds of backups usually lead to disorganised backup sets. (A backup set is ge…

‘Anonymous’ planing to shut down the Internet this Saturday

Notorious hacker group Anonymous has previously stated its intentions to shutdown the Internet on Saturday, March 31st, as a form of protest. “To protest SOPA, Wallstreet, our irresponsible leaders and the beloved bankers who are starving the world for their own selfish needs out of sheer sadistic fun, on March 31, anonymous will shut the Internet down,” the group stated last month. “Remember, this is a protest, we are not trying to ‘kill’ the Internet we are only temporarily shutting it down where it hurts the most.” Operation Global Blackout 2012 looks to shut down the Internet by disabling its core DNS servers, thus making websites inaccessible. Cyber security experts claim that it is unlikely that such an attack would be effective, however, and there is really no need to fear. Read on for more. “The Anonymous hackers can certain cause local pockets of disruption, but these disruptions are going to be localized to networks where their attack machines are located, or where their ‘ref…

Indian student wins YouTube Space Lab Asia-Pacific contest

India's Sachin S Kukke is the Asia-Pacific region winner and one of the six global winners of the YouTube Space Lab 2012 contest for young people to design experiments that could be performed in outer space.
The winners of the contest by YouTube and Lenovo, in cooperation with Space Adventures, NASA, ESA ( European Space Agency), and JAXA (Japan Aerospace Exploration Agency) were announced at a ceremony at the Newseum here Friday.
Kukke's experiment explores transfer of heat in ferrofluid -- a special liquid that gets magnetized when subjected to a magnetic field. The study can benefit development of advanced cooling and heat transfer systems.
A student of mechanical engineering at the BMS College for Engineering in Bangalore, Kukke called on Indian Ambassador to the US Nirupama Rao and shared his experience of conceptualising and carrying out innovative scientific experiments, an Indian Embassy release said.

Warmly congratulating Kukke on his achievement, Rao said that in India, …

Manage your books with Calibre

Kovid Goyal’s “Calibre E-book Management” is a seamless cross-platform library-management tool for ebooks of almost any format under the sun. Its features boggle the mind. Bibliomania doesn’t get better than this! Read on as I walk you through this cool utility.
We all hoard data in one way or another. Some of us have loads of music and some of us have loads of movies. It all began when personal computing became affordable and all of us got to play with these virtual packets of data called files. Then came the Internet and the Napster era — MP3 files flowed in the thousands. That called for some serious media file management — what we now so effortlessly do (most of the time) using Rhythmbox, Amarok or iTunes (if you’re an Apple fan).
HTPC (Home Theatre Personal Computer) Operating Systems like MoviX or their software suite counterparts like XBMC (the XBox Media Center) allow management of not just music, but your videos, TV shows and online radio too. As data grows, it is only its swi…

Pirate Bay servers in Air

The Pirate Bay is always looking at ways of improving itself, but the latest idea is "out there." The site is thinking about creating tiny, flying servers that would act as proxies for the site and hover several kilometers in the air.
"One of the technical things we always optimize is where to put our front machines. They are the ones that re-direct your traffic to a secret location. We have now decided to try to build something extraordinary," The Pirate Bay wrote.
"With the development of GPS controlled drones, far-reaching cheap radio equipment and tiny new computers like the Raspberry Pi, we're going to experiment with sending out some small drones that will float some kilometers up in the air," it said.
The Pirate Bay, against all odds and several attacks, is still up and running serving millions of users around the world. 

The reason why the site has been able to function as long as it has and to continue to do so is in no small part due to its incr…

3 D landmarks in Google Maps

Google Maps and Google Earth in particular would be significantly less fun and less useful without 3D models. Google has been relying on its own data as well as volunteer model makers to create 3D renderings of real-life buildings and landmarks.
Now, it's introducing even more detailed models for more than a thousand important landmarks around the world, when viewed in the wireframe mode that is the default in Google Maps.

"Landmarks have often served as one of the most useful ways to help navigate an unknown area," Google's Paul Messmer, a software engineer working on Google Maps, wrote.

"For example, a Parisian might tell a tourist, 'the cafe you're looking for is just north of the Eiffel tower' because the Eiffel tower is easy to spot and everyone knows how to get there," he said.
"In our ongoing effort to make Google Maps as accurate and useful as possible, we've significantly enhanced the quality of more than a thousand 3D landmarks ar…

Gnome 2 vs Gnome 3 Part 2

Desktops and Window Juggling

GNOME 2's desktop has such a long tradition that little needs to be said about it. Its desktop was a place where you could add launchers for applications, files, or locations. Its windows could be minimized or maximized, and opened somewhere between these two extremes. The main problem was the non-intelligent placement of new windows, which required a Show Desktop applet on the panel as a panic button.

For better or worse, GNOME 3 is a complete rethinking of the desktop. By default, no launchers of any sort are allowed on it. Except for apps like Empathy, whose windows require very little space, everything is open maximized, with no indicator like the windows list to suggest what other else might be buried beneath the active application.

If you are a user with the least tendency to multi-task, this arrangement quickly leads to chaos on the desktop. GNOME 3's solution? A depiction of the open applications on the overview that has no connection to ho…

Gnome 2 vs Gnome 3 Part 1

Users who choose between GNOME 2 and GNOME 3 are rarely making that decision on a purely rational basis. In my experience, users of GNOME 2 are often choosing what they know, while users of GNOME 3 are technophiles who enjoy anything that is new.

Neither is likely to go over the two generations of GNOME feature by feature. In many cases, the choice seems made before login.

But what happens when the two desktop environments are compared in general features? I'm a fan of neither GNOME 2 nor GNOME 3, but I decided to find out.

I spent the day with the two desktop environments open side by side, looked at the desktop components in both, and tried to pick a winner in each basic category based on efficiency, ease of use, and the availability of choices for users.

The effort wasn't always easy. Neither being new nor being traditional was enough in many cases. Frankly, the switch from GNOME 2 to GNOME 3 often looked like an exchange of one set of shortcomings for another.

Still, the …

Facebook Messenger for Windows

After three months of testing,Facebook Messengeris coming to a Windows desktop near you. The social network on Monday announced that Messenger for Windows, a standalone app that lets you IM friends via Windows 7, will be coming out of beta in a few weeks. “Millions of people log into Facebook every day to keep up with friends. They also browse other websites and run computer programs, so it’s easy to miss important stuff,” reads a post on Facebook’s blog. “Maybe a cousin just posted about getting a new job, or a best friend wants to chat about dinner plans for tonight. You should be able to stay in touch anytime, no matter what you’re doing.” Of course, you could do the same thing if you left Facebook open on your browser all day, but this is a way to keep in touch even if you close out of Facebook. The desktop sequel to Messenger has been a long time coming. Facebookintroducedthe Android and iOS-based mobile Messenger app last August. Based on technology from Beluga, a Facebook acquisiti…

Develop apple(ios) applications with Windows

Mobile HTML5 developer framework Sencha wants to be more than just a tool to develop hybrid mobile applications. The company's roadmap for 2012 is to become an end-to-end solution for designing, developing and deploying HTML5 applications and is taking its first steps toward that goal today by releasingSencha Touch 2out of beta.Sencha Touch 2gives developers a better user interface for developing HTML5 that will give consumers a more robust user experience. Sencha also wants to play nice with the mobile development ecosystem. Touch 2 is the first framework that will allow developers to write Android and iOS apps from either a Windows PC or a Mac. That means that iOS developers are no longer tied to XCode on the Mac for building iOS apps. Presenting that freedom to developers should help Sencha win the hearts of many mobile publishers. Sencha is focusing on three core areas for the public release of Touch 2: better consumer user experience, better developer support and development ex…

The power of Bluetooth 4.0

Bluetooth, once trumpeted as the ultimate convenience, quickly proved a headache with plenty of pairing problems and inexplicable connection snafus. Bluetooth 4.0, the newest version of the technology, is about to change all that.

The bad Bluetooth rep
I personally use Bluetooth daily, and love it. My trustyLG BHS-700sworks like a charm. For others, however, living with this technology can be frustrating. Often users are asked to enter annoying passwords before linking devices, and sudden reception drops or other software glitches make Bluetooth feel more painful than fun. Honestly I believe the bad old days of Bluetooth are behind us, especially with Bluetooth 4.0, AKABluetooth Smart Ready, on the edge of mass adoption. Already available in theMotorola Droid RazrandDroid Razr Maxxsmartphones plus Apple'siPhone 4S, Bluetooth 4.0 is expected to hit more handsets and all manner of accessories this year.
