By:CNN.com The  Samsung Galaxy S5  probably isn't the reinvention of the smartphone. But unlike last year's  Galaxy S4 , there's a good chance some of the new features announced could be of actual use to normal human beings. Of course, a few minutes with the Galaxy S5 wasn't enough time to reach a full verdict on the phone, but it was enough to get a basic feel for what  Samsung's   ( SSNLF )  latest offering can and can't do. Display The 5.1 inch display has the same 1080p resolution as last year's 5-inch screen, but due to some new technology, it's definitely brighter, which at the very least, makes everything look nicer. And according to Samsung, the special technology which makes that screen brighter also improves performance in direct sunlight. At the expense of your battery, of course. Fingerprint Scanner Like the iPhone 5S, the fingerprint scanner is probably the most eye-catching of the new features, which adds an extra level of ...

This post will explain how to load files from the res/raw and the Assets folder using a String to specify the file name. Yes, there are a lot of tutorials on this subject, but they all use the automatically generated integer IDs from the R class as inputs and not many of them even mention the possibility of loading files from the Assets folder. As a result of depending on the ID, the file reference must be known beforehand. Instead, the code featured in this post will explain how to find the reference to the file and then load it at runtime based solely on its name. This means that the reference ID and the file don’t even have to exist in the first place, and can be acquired at run time. Before looking into the code, it’s important to highlight the main differences between the raw folder and the Assets folder. Since raw is a subfolder of Resources (res), Android will automatically generate an ID for any file located inside it. This ID is then stored an the R class that will act as a ...

There is an entire science devoted to how humans interact when looking at a page.  Large advertisers have spent millions learning the exact wording for the ad, where to place it, how large it should be, and even what color. As a blogger, you don’t really care that much; nor do you have the time to become a psychology expert.  However you do need to experiment and test to learn how to increase Adsense clicks. After all, an ad spot on your blog is valuable real estate. If it’s not getting enough clicks, you need to rethink your strategy. Some people smother their blog in ads. I have seen blogs with sidebars on either side and ads from top to bottom, most of them flashing messages.  I have even seen blogs still putting ads into their content stream. Not The Best Adsense Strategy Imagine if you go into a room to talk to someone and 15 people surround you; talking to you all at once.  After a few seconds, you would become so frustrated you would probably sc...

The National Security Agency is using secret wireless technology that allows it to access and alter data on computers, even when they are not connected to the Internet, according to a New York Times report. Since 2008, the agency has been increasingly using "a covert channel of radio waves" that can transmit from hardware installed in the computers, according to NSA documents and experts interviewed by the Times. Signals can then be sent to briefcase-size relay stations miles away, according to the report. The NSA has also installed surveillance software on nearly 100,000 computers around the world, according to the Times. The newspaper said the Chinese Army was a frequent target of such technology but said there was no evidence that the agency used either technology inside the US. Repeating earlier denials that its data collection activities are arbitrary or unconstrained, the NSA rejected any comparison to Chinese attackers who have been accused to planting simil...
