Stores in the city of brotherly love are now requiring fingerprint scans of everyone trading in their used games. Even worse, the GameStop Corporation apparently implemented these outlandish anti-theft measures voluntarily.

What’s it like to unbox a supercomputer? Surprisingly, just like unboxing a normal PC August 1, 2014 at 1:37 pm I don’t know about you, but unboxing new gadgets gets me pretty excited. For me, it’s knowing that soon — very soon now, after I cut through the bubble wrap or peel back the protective plastic — the device will burst into life for the very first time. If I’m honest, it actually makes me feel like Frankenstein breathing life into his monster for the first time — especially when I unbox a bunch of components and build them into a new PC. What, then, must it feel like to unbox a brand new petascale supercomputer?

PS4 outselling the Xbox One 3-to-1 as total sales gap grows to 9 million vs. 5 million August 1, 2014 at 9:06 am According to its latest sales figures, Sony outsold Microsoft three-to-one in the quarter ending June 30. During its quarterly earnings call yesterday, Sony said that it had sold a combined total of 3.5 million units of the PS4 and PS3, compared to Microsoft’s quarterly figure of just 1.1 million Xbox One and Xbox 360 consoles. Neither Sony or Microsoft opted to break down these numbers into per-console sales figures, but using previous announcements as a baseline it’s probably around 70-30 in favor of the PS4 and Xbox One. In short, this means Sony sold around 2.5 million PS4s last quarter, compared to about 800,000 Xbox Ones. NASA’s Mars 2020 rover will hunt for signs of alien life, produce oxygen from Mars atmosphere August 1, 2014 at 7:48 am NASA has announced that the next Mars rover — currently codenamed Mars 2020 — will be outfitted with an array of sophisticated, upgraded scientific instruments that will let it delve deeper and farther than Curiosity, with the hope that it will be able to uncover signs of life on Mars. Perhaps even more excitingly, Mars 2020 will also be equipped with a new instrument that can convert the carbon dioxide in Mars’ atmosphere into oxygen — this is of utmost importance if humanity ever colonizes Mars — and another instrument that will gather and store Martian rock samples for eventual return to Earth.
