How Samsung’s Galaxy S6 stacks up against Apple’s iPhone 6 line

Samsung hit its mark with its Galaxy S6 announcement at the World Mobile Congress in Barcelona this week.The company came prepared with an entirely new smartphone design and a concise explanation of the powerful hardware, rich display, strong security, great camera, and intuitive Android Lollipop software. The Galaxy S6 and the Galaxy S6 Edge stood out as high-end hardware designed to compete with top-tier Apple and HTC smartphones.The S6's design and engineering afforded Samsung the luxury to concentrate on just the most important features during the announcement. It eliminated the temptation to add a bloated feature list that consumers often ignore and which mobile device companies are so often inclined to add during product announcements out of a desperation to differentiate me-too devices.To read this article in full or to leave a comment, please click here

EU data protection reform ‘badly broken,’ civil liberty groups warn

Leaked documents show that the European Union’s data protection is on its way to become an empty shell devoid of meaning, European civil rights groups warned Tuesday.The EU is busy overhauling its data protection rules, which date back to 1995. The European Commission and the European Parliament have already agreed on a draft regulation that seeks to modernize data protection rules to take new digital technologies into account.However, there is one more legislative body that has to sign off on the new rules: the Council of the EU, which consists of national ministers of EU member states.Since the Parliament approved the draft with minor changes in March last year, the Council has been busy changing the text. Ministers are expected to agree on how they want to reshape the text by Summer.To read this article in full or to leave a comment, please click here

Is the Samsung Galaxy S6 a true iPhone 6 killer?

The Galaxy S6 is a great-looking phone with great specs -- but is it really an iPhone 6 killer? I've got specs and details. (Note that I'm comparing the non-curved version of the S6 to the iPhone 6, not the iPhone 6 Plus.)ScreenThe nod goes here clearly goes to the S6. It's got a 5.1-inch screen compared to the iPhone's 4.7-inch one. And it wins on resolution as well, 2560 x 1440 at 576 ppi, versus 1334 x 750 at 326 ppi for the iPhone 6.ProcessorThe S6 is powered by an Exynos 7 series quad 2.1GHz chip plus a quad 1.5Ghz, Octacore application processor. The iPhone 6, meanwhile, has an A8 64-bit chip. There's no real way to do a head-to-head comparison on this one, so we'll call it a tossup.To read this article in full or to leave a comment, please click here
