MojoKid writes: Underneath the hood of Apple’s new iPhone 6s and iPhone 6s Plus models is a new custom designed System-on-Chip (SoC) that Apple has dubbed its A9 processor. It’s a 64-bit chip that, according to Apple, is the most advanced ever built for any smartphone, and that’s just one of many claims coming out of Cupertino. Apple is also claiming a level of gaming performance on par with dedicated game consoles and with a graphics engine that’s 90 percent faster than the previous generation. For compute chores, Apple says the A9 chip improves overall CPU performance by up to 70 percent. These performance promises come without divulging too much about the physical makeup of the A9, though in testing its dual-core SoC does seem to compete well with the likes of Samsung’s octal-core Exynos chips found in the Galaxy S6 line. Further, in intial graphics benchmark testing, the A9 also leads the pack in mosts tests, sometimes by a healthy margin, even besting Qualcomm’s Snapdragon 810 in tests like 3DMark Ice Storm Unlimited.

A red/blue/infrared image of the dwarf planet reveals that many of the features we’d seen in earlier images have their own distinctive colors. (credit: NASA/JHUAPL/SwRI ) When last week’s batch of images came down from New Horizons, a number of our readers complained that they were all in black and white. While they gave us a sense of the planet’s rugged features and complex geology, they really didn’t tell us what this icy world looks like. NASA may have been reading the article discussion because the latest batch of images handles the color issue—mostly. Rather than providing RGB images, however, the new batch has data on red, blue, and infrared. So it’s not full color yet, but you can revel in the fact you’re looking at information that your eyes can’t actually see. NASA/JHUAPL/SwRI A red/blue/infrared image of the dwarf planet reveals that many of the features we’d seen in earlier images have their own distinctive colors. 5 more images in gallery In any case, the colors make the planet’s rugged mountains, which show up in red and brown, look even more distinctive compared to the beige-colored plains they border. A partial view of the planet at a specific infrared wavelength shows that the different colors also line up with different chemistries: methane ices are much more common in the icy plains of Pluto than they are in the mountains.

Ars Technica reports that a Federal court in Pennsylvania ruled Wednesday that the Fifth Amendment protects from compelled disclosure the passwords that two insider-trading suspects used on their mobile phones. In this case, the SEC is investigating two former Capital One data analysts who allegedly used insider information associated with their jobs to trade stocks—in this case, a $150, 000 investment allegedly turned into $2.8 million. Regulators suspect the mobile devices are holding evidence of insider trading and demanded that the two turn over their passcodes. However, ruled the court , “Since the passcodes to Defendants’ work-issued smartphones are not corporate records, the act of producing their personal passcodes is testimonial in nature and Defendants properly invoke their fifth Amendment privilege.

An anonymous reader writes: Mozilla launched Firefox 41 yesterday. Today, Adblock Plus confirmed the update “massively improves” the memory usage of its Firefox add-on. This particular memory issue was brought up in May 2014 by Mozilla and by Adblock Plus. But one of the bugs that contributed to the problem was actually first reported on Bugzilla in April 2001 (bug 77999). Read more of this story at Slashdot.

We’re always being told the U.S. is now lagging behind other, more industrious nations in science and technology and basically anything that isn’t spending on the military. How much are we lagging? Here is a depressing graph to help quantify that. Read more…

Compared To the Rest of the World, US 4G (Unsurprisingly) Sucks
Generally speaking, if you thought you might want to blast music while out and about, you’d invest in a Bluetooth speaker. If the sound quality there wasn’t quite robust enough, you’d either get yourself a bigger speaker , or maybe even link together a few smaller ones . Either way, prepare to spend a few hundred dollars. Or not. A new app called AmpMe promises to achieve the same effect, except instead of asking you to shell out for new hardware, it daisy-chains an unlimited number of smartphones so that they stream the same song in sync, combining each handset’s speaker into something… cacaphonous.Slideshow-322368 The free app, available for iOS and Android, doesn’t use Bluetooth or WiFi, but rather, plays an audio “fingerprint” on the host device (a series of beeps, to the human ear) that gets picked up by the mic on the receiving phone. Everyone involved needs to have the app installed, and anyone joining in needs to request a passkey for the music party before receiving that unique audio code. The host can shut down the party at any time with the push of a button, whereas receivers can pause the music for, say, a phone call, and pick back up with the rest of the group, wherever they happen to be in the song. For now, the app only works with Soundcloud. Founder Martin-Luc Archambault says that’s because Soundcloud is free, making it accessible to the most people, but that his team is working on inking deals with other streaming services as well. Ultimately, he says, he wants it to be “Sonos for cellphones.” In a brief demo last week, the various phones and tablets that were paired together did indeed play music in sync, without any latency on any of the devices. AmpMe has clearly shown, then, that it’s possible to turn a series of mobile devices into an ad hoc multi-speaker setup — no small feat. The problem is that the audio quality on most phones and tablets is frankly terrible. Unless you happen to have, say, an HTC phone with BoomSound , you’re probably working with tinny, contained audio that only gets more distorted as you crank the volume. Or, in this case, create a chorus of equally tinny-sounding devices. It’s great to know that the technology has evolved such that it’s possible to daisy-chain phones like this and have them stream music perfectly in sync. Now we just need to wait the phone makers to catch up. Source: iTunes , Google Play

The image of a dinosaur tramping around in the snow feels totally wrong — these behemoths ruled a tropical world. But one duck billed dinosaur, at least, managed to endure long, dark winters far north of the Arctic Circle some 69 million years ago. Read more…

New submitter joesreviewss writes: Groupon is laying off about 10% of its workforce and is shutting down operations in seven countries. 1, 100 people worldwide will be let go and the company will take a pre-tax charge of $35 million in the process. A Groupon statement reads in part: “Let’s be clear: these are tough actions to take, especially when we believe we’re stronger than ever. We’re doing all we can to make these transitions as easy as possible, but it’s not easy to lose some great members of the Groupon family. Yet just as our business has evolved from a largely hand-managed daily deal site to a true ecommerce technology platform, our operational model has to evolve. Evolution is hard, but it’s a necessary part of our journey. It’s also part of our DNA as a company and is one of the things that will help us realize our vision of creating the daily habit in local commerce.” Read more of this story at Slashdot.
