Subject: School District incorporating cell phones into lesson plans Message-ID: <d800f1ae-b2c6-4348-bbdc-2cec3b1b2fd7@w24g2000vby.googlegroups.com> "As schools fight the rising tide of student cell phone use, the Hopewell Valley [NJ] Regional School District has embraced the trend. The district is piloting a program dubbed "Bring Your Own Device" that will put in-class cell phone use into lesson plans for eighth-graders and high school students. For example, students can use them to covertly alert teachers they don't understand. What the teacher can say is, 'Does everybody understand where we are?' and without fear of embarrassment from their friends, they can text in 'No' or 'Can you clarify?'" for full article please see: http://www.nj.com/mercer/index.ssf/2012/06/hopewell_valley_schools_go_hig.html

Subject: Reliance on smartphones is leaving hikers in a bind Message-ID: <p062408f9cc0e4a410bbd@[]> A call to be better prepared Reliance on smartphones is leaving hikers in a bind By Billy Baker Globe Staff / June 25, 2012 It was getting dark. They were lost atop Mount Lafayette in the White Mountains. And Analia Oliva and her boyfriend, Cory Robertson, out for a day hike with their dog, were not prepared for a night in the woods. The only tool they had with them was Oliva's iPhone. Except that they had no reception, and Robertson, 25, and Oliva, 20, had used up much of the battery taking photos. The New Hampshire couple eventually found the right trail, scrambled down the mountain, hoping to get a signal, but it was too late. They could not see where they were walking, and there were no bars on the phone. When it died, they settled into the reality of a night on the mountain. That is when a minor miracle happened: They were rescued, accidentally, by crews out looking for another lost hiker. Increasingly, smartphones are creating problems in the backcountry, particularly in New Hampshire's White Mountains, where, officials say, more hikers are skipping basic gear - particularly a map, compass, and flashlight - and relying too heavily on phones with GPS and a slew of gear-like apps, including compasses and trail maps, to bail them out of a jam. ... http://www.boston.com/news/local/massachusetts/articles/2012/06/25/iphones_can_save_hikers_from_danger_and_put_them_in_it/ http://www.bostonglobe.com/metro/2012/06/24/iphones-can-save-hikers-from-danger-and-put-them/8K3qj5zu3RJh87wlzDmZLI/story.html

Subject: T-Mobile likely to end attempt to block Verizon spectrum purchase Message-ID: <p06240802cc0e974cbd6b@[]> T-Mobile likely to end attempt to block Verizon spectrum purchase Spectrum and cash swap allay T-Mobile's antitrust concerns. by Jon Brodkin Ars Technica June 25 2012 When Verizon Wireless struck a deal to buy new spectrum for $3.6 billion, T-Mobile USA was the first to ask the government to block the sale. Verizon's purchase of airwaves from SpectrumCo, a joint venture of Comcast, Time Warner, and Bright House, raised antitrust concerns because the spectrum was needed more by smaller competitors who would "use it more quickly, more intensively, and more efficiently," T-Mobile said in February. But this morning, Verizon announced a deal that seems all but certain to end T-Mobile's opposition. The companies will trade spectrum and cash, with the deal being contingent on the approval of Verizon's purchase of licenses from SpectrumCo, Cox, and Leap Wireless. ... http://arstechnica.com/information-technology/2012/06/t-mobile-likely-to-end-attempt-to-block-verizon-spectrum-purchase/

Subject: How SSDs conquered mobile devices and modern OSes Message-ID: <p06240803cc0e97ede33b@[]> How SSDs conquered mobile devices and modern OSes With flash ascendant, OS vendors have disabled defragging and supported TRIM. by Lee Hutchinson Ars Technica June 25 2012 In part one of our "SSD Revolution" series, we covered the basics of flash memory in solid state drives, walking through lots of important but esoteric details such as the difference between NAND flash and NOR, or how SSD reads and writes work. We also talked about the techniques used to make SSDs faster and to prolong their lives. But SSDs don't just exist in a vacuum-the state of solid state, such as it is, has had a significant effect on the shape of the modern mobile device landscape, which we explore now in part two. Not long ago, flash-based MP3 players occupied the low end of the capacity spectrum and, while some brave souls were using PCMCIA compact flash cards in their laptops, you still needed a real hard disk drive to effectively boot and use Windows or OS X. Not anymore-not only are flash-powered, high-capacity MP3 players and laptops standard, but modern operating systems are quickly adapting to SSDs as the norm. An entire class of ultrabooks-which, in spite of what the name suggests, do not contain hyperdrives, organic CPUs based on alien DNA, or anything else truly deserving of the "ultra" prefix-are now built around the MacBook Air's design philosophy of being durable, thin, light... and stuffed full of NAND flash. Laptops of this form factor seem poised to deliver on most of the promises that netbooks once made (especially portability and battery life) without falling prey to the same set of compromises that ultimately doomed netbooks to hobbyist devices. Tablets, too, are on the rise. The tablet segment of the mobile device market didn't even meaningfully exist prior to 2010-say what you will about the iPad, but it truly sparked a revolution. Since their rise to prominence, all mainstream tablets have been exclusively flash-powered devices; there's not a hard disk to be found anywhere in the lot. While the SSD craze might be sweeping the "real" computer segment as flash storage becomes more common on desktops and laptops, the place where NAND flash most truly empowers consumers is in mobile devices. But things were not always thus, and flash wasn't always the best choice for mobile devices to store data. ... http://arstechnica.com/information-technology/2012/06/inside-the-ssd-revolution-mobile-devices-and-modern-oss/
