Trailrunner7 writes "Those of you who like to tinker and jailbreak Android phones should take notice of some new research conducted on Samsung Galaxy S4 Android devices shipped by AT&T and Verizon. Both devicemakers ship the Galaxy S4 smartphones with a locked-down bootloader that prevents users from uploading custom kernels or from making modifications to software on the phone. Azimuth Security researcher Dan Rosenberg has found a vulnerability in the manner in which the devices do cryptographic checks of boot image signatures and was able to exploit the flaw and upload his own unsigned kernel to the device."

An anonymous reader writes "Twilio's Jon Gottfried has written an article about the lessons he's learned after six months of developing software for Google Glass. He has some insightful points: 'I expected it to be very similar to building mobile applications for Android. In fact, I began learning to build Android applications in preparation. My efforts were for naught, because the Mirror API is a RESTful web service. This means that developing applications for Glass is actually more similar to building a website than it is to building an Android application.' He also talks about how this fits in with the future of technology: 'I would argue that Google took the only option available to them. The only truly scalable products of the future will be developer platforms. Facebook, Twitter, Twilio, Google, Apple, Microsoft, Arduino – all of these products have been successful in large part by embracing and empowering their developer communities. No company is omniscient enough to imagine every potential use of their products. This gives developers an immense amount of power to define the success or failure of an entire product line.'"

An anonymous reader writes "As we in the U.S. settle in for Memorial Day weekend, this article points out how our cultural addiction to technology is making it less of a vacation than it used to be. 'The average smartphone user checks his or her device 150 times per day, or about once every six minutes. Meanwhile, government data from 2011 says 35 percent of us work on weekends, and those who do average five hours of labor, often without compensation — or even a thank you. The other 65 percent were probably too busy to answer surveyors' questions.' Even for those of us who don't have any work to do over the weekend, we'll probably end up reading all of our work-related emails as they roll in, and take time out of our day to think about what's going on — to the detriment of our weekend activities: 'A study at the University of California, San Francisco, found that new experiences fail to become long-term memories unless brains have downtime for review.' I imagine it's even worse for your average Slashdotter, who's likely plugged in to more technology at home and at work. How can we make our employers understand that downtime needs to remain downtime? 'It took labor unions 100 years to fight for nights and weekends off, some say, while smartphones took them away in about three years.'"

An anonymous reader writes "While everyone was glued to the Xbox One announcement, Nvidia GeForce GTX 780 launch, and Intel's pre-Haswell frenzy, it seems that AMD's launch was overlooked. On Wednesday, AMD launched its latest line of mobile APUs, codenamed Temash, Kabini, and Richland. Temash is targeted towards smaller touchscreen-based devices such as tablets and the various Windows 8 hybrid devices, and comes in dual-core A4 and A6 flavors. Kabini chips are intended for the low-end notebook market, and come in quad-core A4 and A6 models along with a dual-core E2. Richland includes quad-core A8 and A10 models, and is meant for higher-end notebooks — MSI is already on-board for the A10-5750M in their GX series of gaming notebooks. All three new APUs feature AMD HD 8000-series graphics. Tom's Hardware got a prototype notebook featuring the new quad-core A4-5000 with Radeon HD 8300 graphics, and benchmarked it versus a Pentium B960-based Acer Aspire V3 and a Core-i3-based HP Pavillion Sleekbook 15. While Kabini proves more efficient, and features more powerful graphics than the Pentium, it comes up short in CPU-heavy tasks. What's more, the Core-i3 matches the A4-5000 in power efficiency while its HD 4000 graphics completely outpace the APU."

Krystalo writes "In a nod towards the modding community and hackers in general, Google has released the first factory system image and rooted bootloader for the latest version, XE5, of Google Glass. Nevertheless, the company is at the same time warning that using these downloads will result in a voided warranty for the experimental device."

kgeiger writes "The next billion customers have to come from somewhere. The Wall Street Journal today reports that Google will fund, deploy, and manage wireless networks in sub-Saharan Africa and Southeast Asia. From the article: 'The Silicon Valley company is deep in the throes of a multipronged effort to fund, build and help run wireless networks in emerging markets such as sub-Saharan Africa and Southeast Asia, said people familiar with the strategy. The wireless networks would be available to dwellers outside of major cities where wired Internet connections aren't available and could be used to improve Internet speeds in urban centers, these people said.'"

redletterdave writes "After AT&T unceremoniously canceled the HTC First after just one month on the market, Facebook announced the first phone running the Facebook Home operating system will not be launching in the U.K., as originally planned. From Facebook: 'Following customer feedback, Facebook has decided to focus on adding new customization features to Facebook Home over the coming months. While they are working to make a better Facebook Home experience, they have recommended holding off launching the HTC First in the UK, and so we will shortly be contacting those who registered their interest with us to let them know of this decision. Rest assured, we remain committed to bringing our customers the latest mobile experiences, and we will continue to build on our strong relationship with Facebook so as to offer customers new opportunities in the future.'"

x_IamSpartacus_x writes "Jolla, the Finnish company that continued Nokia's work on the MeeGo mobile platform, announced details of its first smartphone on Monday. Availability for the Jolla device is expected by year end and can be pre-ordered now; the phone will be priced at no more than €399 (US $512.26). The Jolla hardware looks similar to that of Nokia's Lumia, with a clean, button-less front face that houses the 4.5-inch touchcscreen. The phone will use a dual-core processor and support 4G LTE in some regions. Internal storage tops out at 16 GB, but can be expanded via microSD card. The phone also includes an 8 megapixel rear camera with auto focus. The phone is also 'Android app compliant' which, in a move similar to that of BlackBerry, can help with available apps at launch."

puddingebola writes with this excerpt from a Bloomberg report: "The Pentagon cleared Apple Inc. (AAPL) devices for use on its networks, setting the stage for the maker of iPhones and iPads to compete with Samsung Electronics Co. and BlackBerry for military sales. The Defense Department said in a statement [Friday] that it has approved the use of Cupertino, California-based Apple's products running a version of the iOS 6 mobile platform. The decision eventually may spur a three-way fight for a market long dominated by Waterloo, Ontario-based BlackBerry.'" Also, Apple devices are best for uploading viruses to alien craft.

With the kind of cagey phrasing found in many such electronics approval applications, Google describes a device that some are taking to be the successor to its discontinued Nexus Q thus: "The device functions as a media player." From the article: "Some of the specs of the device includes a 2.4GHz WiFi b/g/n connectivity. The FCC report does not contain test photos so we do not know what the device looks like. It is likely that the H840 will support Google Play Music All Access and will have similar functionality as a Sonos media player that can be connected to external speakers."

An anonymous reader writes "For years, Bell Mobility customers in northern Canada were charged 75 cents a month for 911 emergency service. The problem is that cellphone users outside Whitehorse, Yukon, don't have access to 911 service. The Supreme Court of the Northwest Territories ruled against Bell this week, following a class action lawsuit which challenged the phantom cellphone 911 billings. Subject to a possible final appeal to the Supreme Court of Canada, Bell will likely owe 30,000 northern cellphone subscribers some bucks."

First time accepted submitter iinventstuff writes "The Idaho National Laboratory has built a dirty bomb detection network out of cell phones. Camera phones operate by detecting photons and storing them as a picture. The INL discovered that high energy photons from radiological sources distort the image in ways detectable through image processing. KSL TV reports that the INL's mobile app detects radiation sources and then reports positive 'hits' to a central server. Terrorists deploying a dirty bomb will inevitably pass by people carrying cell phones. By crowdsourcing cell phones, the INL has created a potentially very large, inexpensive, and randomly mobile radiation detection grid."

Today eight members of the U.S. Congress have sent a letter to Google's Larry Page, asking him to address a number of privacy concerns about Google Glass. In the letter (PDF), they brought up the company's notorious Street View data collection incident, and asked how the company was planning to avoid a similar privacy breach with Glass. They also ask how Google is going to build Glass to protect the privacy of non-users who may not want their every public move to be recorded. Further, they ask about the security of recordings once they are made: "Will Google Glass have the capacity to store any data on the device itself? If so, will Google Glass implement some sort of user authentication system to safeguard stored data? If not, why not?" Google has until July 14th to respond.

New submitter WillgasM writes "A bit of good news for American travelers, according to the New York Times: 'After years of criticism of the wireless service on its trains, Amtrak announced on Thursday that it had upgraded its cellular-based Wi-Fi using broadband technologies that will improve the speed and reliability of the Internet in its passenger cars.' So far the service has been rolled out on the high-speed Acela lines and a few routes in California, but they hope to have the rest of their trains upgraded by the end of Summer. We're still an order of magnitude away from high-speed rails in other countries, but it's nice to know someone's trying."

alancronin sends this excerpt from ZDNet: "... the trend that brutally undercut BlackBerry phones during the past five years — the 'bring your own device' movement — is now driving significant sales of BlackBerry Enterprise Service (BES), the company's backend software. 'Our customers have been asking, "Can you just take what you've done on BlackBerry and put it on iOS and Android?"' said Pete Devenyi, BlackBerry's SVP of Enterprise Software. ... Secure Work Space will be an app in the Apple App Store and Google Play, pending approval from Apple and Google, respectively. It will include secure email, calendar, contacts, tasks, and document editing. It won't allow data leakage including copy and paste between Secure Work Space and the rest of the device. IT will be able to remotely wipe everything in the Secure Work Space without affecting any of the other apps or data on the person's device, in a BYOD scenario."

kenekaplan writes "In an interview with The Atlantic before stepping down as CEO of Intel, Paul Otellini reflects on his decision not to make a chip for the then yet released iPhone. 'The lesson I took away from that was, while we like to speak with data around here, so many times in my career I've ended up making decisions with my gut, and I should have followed my gut,' he said. 'My gut told me to say yes.'"

colinneagle sends this quote from an article at NetworkWorld: "I run a very nifty desktop utility called Rainmeter on my PC that I heartily recommend to anyone who wants to keep an eye on their system. One of its main features is it has skins that can monitor your system activity. Thanks to my numerous meters, I see all CPU, disk, memory and network activity in real time. the C: drive meter. It is a circle split down the middle, with the right half lighting up to indicate a read and the left half lighting up for write activity. The C: drive was flashing a fair amount of activity considering I had nothing loaded save Outlook and Word, plus a few background apps. At the time, I didn't have a Rainmeter skin that lists the top processes by CPU and memory. So instead, I went into the Task Manager, and under Performance selected the Resource Monitor. Under the Processes tab, the culprit showed its face immediately: AppleMobileDeviceService.exe. It was consuming a ridiculous amount of threads and CPU cycles. The only way to turn it off is to go into Windows Services and turn off the service. There's just one problem. I use an iPhone. I can't disable it. But doing so for a little while dropped the CPU meters to nothing. So I now have more motivation to migrate to a new phone beyond just having one with a larger screen. This problem has been known for years. AppleMobileDeviceService.exe has been in iTunes since version 7.3. People complained on the Apple boards more than two years ago that it was consuming up to 50% of CPU cycles, and thus far it's as bad as it always has been. Mind you, Mac users aren't complaining. Just Windows users."

An anonymous reader writes "PayPal on Monday announced a new Android SDK that tries to make it easier for developers to accept in-app payments on Google's mobile platform. The company says the software development kit will be available for US developers on May 15. The Android debut comes just over two months after the mobile SDK for iOS, which supports iOS 5+ on all varieties of iPhone and iPad screen sizes and resolutions. At the time, PayPal said an Android flavor was coming, and now it has delivered: its SDK will support version 2.2, meaning Froyo (released in May 2010), and above."
