The first company that visited our campus did leave me with an unforgettable experience. M Cube is a very different kind of company from the scratch. Why?
1. Their aptitude test has no mathematics or logic or the other standard sections that you find in other papers
2. Only 2 questions, 1 hour time to solve
3. Both the questions will be algorithmic puzzle expected to test your analytic reasoning.
4. The interviewers question on linked lists, FIFO, circular linked lists, trees, and all other data structure concepts you can possibly think of.
5. They worry a lot on space and time complexity.
The 2 questions that we got :
1. Consider a string. Devise an algorithm to find all possible circular rotations of the string.

The Aliens have landed, the Aliens have landed !!
Alienware was initially a separate firm that aimed at making high configuration computers to satisfy the hardcore gamer's need. It was later on acquired by Dell and is now a wholly owned subsidiary of Dell computers. Alienware added a lot of new products to Dell, including AMD processors. To prevent cross-market products, Dell continues to run Alienware as a separate entity. The exclusive Alienware Gaming Zone in Bangalore will offer a 3D gaming experience with graphics, performance and the latest in computing technology, with 16 high-end Alienware gaming machines.
J. Suhas, Brand Manager for Alienware, said that the café won’t be providing Counter Strike 1.6 (w00t!) But, gamers do get an opportunity to experience the latest and most advanced gaming machines such as the Alienware Aurora ALX desktop and did I mention WiFi connectivity.
The few eye popping specifications of the Alienware Aurora ALX desktop are :
- Overclocked Intel core i7 975 extreme edition processor, 3.33GHz (8Mb cache) Quad core processor.
- ATI CrossFireX - Dominate any game with an ultimate multi-GPU performance gaming platform with Microsoft® DirectX® technology.
- NVIDIA SLI - Don’t dial back game settings; crank ’em up. With NVIDIA® SLITM graphics and Microsoft® DirectX® technology, you can experience your digital media like never before.
- Up to 4 SATA2 3.0Gb/s Storage Drives.
The Alienware spaceship is at # 644, 80 Feet Road, Koramangala 4th Block in Bangalore. So gaming freaks, enjoy...

When Facebook's privacy settings can lock you out...
Facebook has undoubtedly grown into one of the biggest social platforms, outperforming Google's Orkut, Buzz and the popular MySpace. Its developer API has made way for some of the most addictive games like Mafia Wars and FarmVille. But, the security and privacy settings they adopt can sometime lock you out of your own account.
For instance, here is a true story of my friend who was an active Facebook user and had over 928 friends!! He is studying in Bangalore and so uses Facebook here. When he went to his native for vacations this time and tried to access his account there, he got locked out. The reason being - they doubt whether it was him accessing the account because its from an unfamiliar place for that account. Here is the exact wordings used by facebook to show the error - " Your account was recently accessed from a location we're not familiar with. For your protection, please review your recent activity to make sure no one is using your Facebook account without permission.
Reviewing your activity takes just a few moments. We'll start by asking you a couple of questions to confirm that this is your account. (If we recognize your computer, you'll be able to skip this step.) "
Okay, they give you profile pictures of your friends and ask you to identify in order to authenticate the account. But, the funniest part is, they give pictures of your friend's farms (virtual farms created using FarmVille) and ask you questions like "Whose farm is this?". Can you beat that. My friend obviously didn't know whose farm it was, he never was the "farming" kind too. So facebook decides that he's an intruder and locks him out of his own account. Apparently the situation is called a Roadblock.

Apple now keeps mouse away
Apple on Tuesday unveiled the Magic Trackpad, a touchpad which allows a user to operate the computer using only the gestures made by the finger, thereby eliminating the need for a mouse. The Magic Trackpad costs $69 in the online Apple Store. The battery-powered device looks like a notepad and is made of aluminum and glass. It operates using the Bluetooth wireless technology. The entire surface of Magic Trackpad is one large button, so you can click and double-click anywhere. Magic Trackpad also supports a full set of gestures, including two-finger scrolling, pinching to zoom, rotating with your fingertips, three-finger swiping, and activating Exposé or switching between applications with four fingers. The device incorporates the pinchs and gestures familiar to Apple i Phone users. The maximum range of the device is said to be 33 feet away from the computer and is already featured in Apple's Macbook Pro notebook.
The Trackpad stripped :
World's first 3D camcorder
The 3D revolution has been rapidly spreading, starting from movies like Avatar to home entertainment that includes 3D TVs and 3D mobile displays. The latest addition to this family is the World's first 3D camcorder, launched by Panasonic on Wednesday.
The HDC-SDT750 3D, priced at £1,300 works on a sophiscated double lens model. Company spokesman Barnaby Sykes said "Just as we have two eyes, the camcorder has two lenses side by side". The camcorder imitates the human brain by merging the images from the two lenses to create a single 3D vision. The images recorded can be viewed on the already available 3D TVs. Also, it is capable of recording full-definition images even if the 3D lens is detached from the camera. It features a time lapse recording that plays scenes at a desired accelerated speed. The camcorder is expected to be available from September.

Is Java Dying ???
Though many projects still continue to be developed using Java, some analysts predict that the language is already dying, especially in the SOA world. SOA emphasizes interoperability more than cross-platform deployment, and the analysts say that Java EE is ill-suited for this (despite the existence of efforts such as Project Tango to directly address this.)
Lets try to separate fact from fiction in this discussion. Only a small percentage of developers go to conferences like JavaOne. These people constitute the majority of those who read, write and comment on blog sites and they are the first-adopters of new technologies and languages. These people are enthusiastic evangelists of new and cool technologies fueling, for example, the rise of Dynamic languages (which I applaud). But these same folks can be vocal complainers, ignoring possible work-arounds of existing features in languages such as Java, and predicting the death of Java. For many developers, these dire predictions can inspire fear for their jobs, compelling some to prematurely drop Java, further perpetuating the rumor that Java is indeed dying.
It is impressive that Java has been consistently popular for over 12 years (Ruby was created in 1995, but only really became popular once David Heinemeier Hansson released Ruby on Rails in 2004). In our industry it’s impossible to predict how something will be used in a decade and maybe we shouldn’t try. Have Sun got carried away with the popularity of Java and tried to make it into something it wasn’t designed to be, creating an overly complex beast? Are these proponents of Java-Death simply Java gurus that who are just seeking perfection?
