Samsung Galaxy S5: Survival of the Fittest?

With the release of Android mobile OS, Google opened a floodgate of new mobile technology. With the release of newer and better devices every day from various companies it has been ensured that mobile technology becomes as pervasive as possible. I don’t know about anyone else but my phone is surely the center of my world. The market of smart phones has become so competitive that a company can’t survive just by creating ‘good’ products. The products must have something extra that makes people want it.

Samsung’s latest release has taken the cake for me in that regard. With the release of Samsung Galaxy S5 along with Gear 2 and Gear Fit, the company has created a buzz in the smart phone market. And why should it not when the features are awesome! As I write this article, I have no idea which feature I should deem to be the best. From looks to functionality the phone is a top notch premium piece of technology.

Here’s a look at the features:

With a unique perforated back cover and four different vivid colors, the phone looks amazing and has a comfortable grip too. It has a 5.1 inch full HD super amoled screen with adaptive display which makes video viewing an experience of a lifetime. For photography enthusiasts, the phone offers at 16 megapixel rear camera with autofocus feature. Samsung claims the speed of autofocus to be 0.3 seconds. It has both contrast autofocus and phase detection autofocus which is a world first in smart phones.

Small Apartment turned into Cool Living Space!!! WTF

Christian Schallert 258 square-foot apartment is one strong example of how we can use our living spaces efficiently. It has got all things from shower and bathroom, utilities such as dishwasher, stove and fridge, cupboards for clothing, portable bed and sofa, dining table all hidden behind the walls.

His inspiration to building such kind of place is living boats. I wonder how much money had he spent for building this space. Anyways, a nice idea to keep you active and fit while you slide and fold everything out of sight.

Free Dataset Repositaries for Data Mining and Visualizations

People in database, datamining, data visualizations and business intelligence require datasets (sets of data) to implement, run and test their algorithms. There are a lot of resources on the internet where you can get synthetic and real datasets for free. Some of the datasets can be benchmark datasets for testing algorithm performance with industry standards. Here I am documenting some of the free resources on the internet that will help you out in your data search for academics and industry needs. I will try to keep this list updated overtime.

P.S. : Before using any of below mentioned datasets please read their respective usage policies.

How a Hacker took hold of Times Square Digital Screens

This is what technology can do it for you. A hacker or geek (whatever) demonstrates how with iPhone, transmitter and repeater one can easily take over the control of what is displayed on the digital screen. He plugs in the transmitter into the headphone minjack of iPhone and then plays the any video and then this transmitter sends signal to repeater which is held close to the digital screen and you can see this video playing on the hacked screen. He chose times square only because there were a lot of screens to test on at this place. I wonder whether this hack works for other phone firmwares (symbians, blackberrys, android) also. Anyways it is open for anyone to try if that works.

I am also a bit in doubt of whether this is real or fake, but it is worth a try. Post in your comments about whether this works with other phones also or not.
