Where Cellular Networks Don't Exist, People Are Building Their Own 104

New submitter TechCurmudgeon writes: According to a story at Wired, towns in Mexico that aren't served by the nation's telecom monopoly are taking matters in their own hands with the help of a non-profit and open source technology. "Strategically ignored by Mexico's major telecoms, Yaee is putting itself on the mobile communications grid with the help of a Oaxaca-based telecommunications non-profit called Rhizomatica." A locally-made tower is the backbone of Yaee's first cellular network. The town's network is composed of two antennas and an open-source base station from a Canadian company called NuRAN. Once Yaee gets the tower installed and the network online, its 500 citizens will, for the first time, be able to make cell phone calls from home, and for cheaper rates than almost anywhere else in Mexico.

Ars: Samsung Gear VR Is Today's Best Virtual Reality 74

An anonymous reader writes: Samsung took a distinctly different tack from Oculus VR in developing virtual reality tech. Whereas Oculus has a dedicated device, Samsung simply has a high-tech piece of headgear that you strap a Galaxy Note 4 phone into. A review popped up at Ars Technica after a month using the device, and they say it works surprisingly well. Quoting: "Though the weight of the two units is comparable, the Gear VR benefits from a strap system that distributes that weight on the upper forehead and the back of the skull rather than through an elastic death grip around the eye area."

They still say a purchase is hard to justify, simply because the content selection is lacking. But as that improves, the price tag will become worth it. "Simple, minimally interactive virtual reality experiences like The Deep, BluVR, and Titans of Space have become go-to apps when passing the Gear VR around a party for friends to check out. It's incredible just sitting in place and following along with your gaze as sea life or entire planets fly by in sharp, well-rendered, 360-degree glory."

PC Shipments Are Slowly Recovering 130

mrspoonsi sends this news from TechCrunch: Over the past two years, the growing popularity of mobile devices has eaten into PC sales. A new report by Gartner, however, shows that shipments may continue to enjoy a very slow but steady uptick this year as tablet sales hit a peak. The research firm found that worldwide PC shipments in the fourth quarter of 2014 grew one percent year-over-year, the first increase since 2012. In the U.S., PC shipments increased 13.1 percent year-over-year, the fastest increase in four years, thanks to holiday purchases. Inexpensive laptops (about $200 to $300), thin and light notebooks, and laptops with a detachable screen helped drive growth. Lenovo continued to be the number one PC maker in terms of shipment volume, with a 19.4 percent marketshare.

Asus Wireless Routers Can Be Exploited By Anyone Inside the Network 68

An anonymous reader writes A currently unpatched bug in ASUS wireless routers has been discovered whereby users inside a network can gain full administrative control, according to recent research conducted by security firm Accuvant. Although the flaw does not allow access to external hackers, anyone within the network can take administrative control and reroute users to malicious websites, as well as holding the ability to install malicious software. The vulnerability stems from a poorly coded service, infosvr, which is used by ASUS to facilitate router configuration by automatically monitoring the local area network (LAN) and identifying other connected routers. Infosvr runs with root privileges and contains an unauthenticated command execution vulnerability, in turn permitting anyone connected to the LAN to gain control by sending a user datagram protocol (UDP) package to the router. In relevant part: The block starts off by excluding a couple of OpCode values, which presumably do not require authentication by design. Then, it calls the memcpy and suspiciously checks the return value against zero. This is highly indicative that the author intended to use memcmp instead. That said, even if this check was implemented properly, knowing the device’s MAC address is hardly sufficient authentication,” said Drake. Here are the technical details at GitHub.

EFF: Apple's Dev Agreement Means No EFF Mobile App For iOS 220

schwit1 writes The EFF launched a new app that will make it easier for people to take action on digital rights issues using their phone. The app allows folks to connect to their action center quickly and easily, using a variety of mobile devices. Sadly, though, they had to leave out Apple devices and the folks who use them. Why? Because they could not agree to the terms in Apple's Developer Agreement and Apple's DRM requirements.

Ask Slashdot: High-Performance Laptop That Doesn't Overheat? 325

AqD writes: Last year we started to replace business/multimedia-grade laptops with gaming laptops at work, after several years of frustration with overheating and throttling issues that plagued our laptops from Acer, ASUS, Dell, Lenovo, and basically every brand you can find on market, making it impossible to write code and run db/test environment all on the same laptop.

The first new batch comes from Clevo because their gaming laptops don't look like gaming laptops, and they offer 3-6 disk slots which we badly need. The result is acceptable, however, not quite as good as I had expected. Mine has i7-4700mq CPU which is more or less equivalent to an older i7 on the desktop, but its temperature is raised to 70-80C while turbo boost is on, even with the best thermal paste. My friend's i7-4801mq is worse — it could never stay at the advertised 3.6GHz for more than a few seconds before it burns up over 90 and starts to throttle. Its benchmark result is nearly identical to the 4700mq because of heat problems. And it's only 3.6GHz! The best i7 CPU on a desktop could easily run closer to 5GHz with 6 cores / 12 threads running!

So what should we choose next time? We're not looking for something cool or slim or light. We need real laptops which can at least run prime calculation at advertised turbo boost speed, full cores/threads for an entire day. A nice bonus would be manual fan control plus easy access to the fan for cleaning.

The Fire Phone Debacle and What It Means For Amazon's Future 155

HughPickens.com points out an article at Fast Company that dug into the creation of Amazon's floundering Fire Phone to figure out why the company pushed so hard to bring it to market. The piece is an indictment of Jeff Bezos's determination to make the Fire Phone into a competitor for an already-saturated high-end smartphone market. "This wasn't some vague guideline from an executive busy running other parts of the business; based on interviews with more than three dozen current and former employees, most of whom were deeply involved with the project, the CEO drove every aspect of the phone’s creation from the outset."

Now that Amazon's growth is slowing and profits have yet to be seen, investors and analysts have run out of patience for gambles like this one. "What makes the Fire Phone a particularly troubling adventure, however, is that Amazon’s CEO seemingly lost track of the essential driver of his company’s brand. It’s understandable that Bezos would want to give Amazon a premium shine, but to focus on a high-end product, instead of the kind of service that has always distinguished the company, proved misguided."

Sony Thinks You'll Pay $1200 For a Digital Walkman 391

An anonymous reader writes: The Walkman is one of the most recognizable pieces of technology from the 1980s. Unfortunately for Sony, it didn't survive the switch to digital, and they discontinued it in 2010. Last year, they quietly reintroduced the Walkman brand as a "high-resolution audio player," supporting lossless codecs and better audio-related hardware. At $300, it seemed a bit pricey. But now, at the Consumer Electronics Show, Sony has loudly introduced its high-end digital Walkman, and somehow decided to price it at an astronomical $1,200.

What will all that money get you? 128GB of onboard storage and a microSD slot to go with it. There's a large touchscreen, and the device runs Android — but it uses version 4.2 Jelly Bean, which came out in 2012. It also supports Bluetooth and NFC. Sony claims the device has 33 hours of battery life when playing FLAC files, and 60 hours when playing MP3s. They appear to be targeting audiophiles — their press release includes phrasing about how pedestrian MP3 encoding will "compromise the purity of the original signal."

Microsoft Unveils Nokia 215, a $29 Phone With Internet Access 150

An anonymous reader sends word of the Nokia 215, Microsoft's $29 internet-ready phone. "Smartphones may be more affordable than ever, but, for quite a few people, they are still too expensive. And they offer short battery life, pretty much across the board. It is not a winning combination, especially for those living in developing markets, looking to be connected to the Internet while on the go. Enter Nokia 215, a dirt-cheap Internet-ready phone, which Microsoft announced earlier today. It packs some of the most-important features people want in a smartphone, but without any of the major drawbacks. The software giant calls it its "most affordable Internet-ready entry-level phone yet", costing just $29."

What Isn't There an App For? 421

An anonymous reader writes: "There's an app for that!" It's been both an educational comment and a joke for years, now. There are so many small, single-purpose pieces of software available that it's impossible to keep track of everything apps can do. Indeed, when I'm looking for more usefulness out of my phone, I tend to browse the various app stores for interesting software, trying to figure out what more the phone can do for me. But a recent article turns that around and asks: for what tasks does the software have yet to be written? Though most of the article itself doesn't focus on that subject, it got me thinking about apps I'd like to see. (Which was harder than I expected.) I'd like an app that'd help me diagnose bad noises my car makes. I'd like one that can aggregate all my communication channels into one screen. I'd like one that can easily pick up program states from one PC — like an IDE session — and carry them to another PC. What apps are you still waiting for?

Ask Slashdot: Linux Distro For Hybrid Laptop? 210

Steve Parrish writes: I needed a new laptop and found a great deal on an Asus Transformer TP500L. It's one of the laptops where you can flip the screen back and use it as a tablet. I'd like to replace Windows 8.1, and I'm having a difficult time finding a Linux distro that will work on it. I'm familiar with Mint, SolydX, and older Ubuntu versions. I tried the latest Ubuntu with Unity and didn't like it, but the OS installed with only a few minor issues. Has anyone tried any other distros on a hybrid laptop with a touchscreen? I've used Linux for several years, but I'm no guru -- I'm not comfortable with the command line or other advanced workings. Any suggestions would be appreciated.

Unofficial WhatsApp Library Gets End To End Encryption Before Official Clients 29

An anonymous reader writes Earlier last year WhatsApp announced partnership with Open WhisperSystems to integrate the ratcheting forward secrecy protocol found in their app called TextSecure, into WhatsApp. The protocol is supposed to provide end-to-end encryption between WhatsApp clients. So far it has been implemented only in WhatsApp on Android, with the rest of platforms yet to come. The implementation however has already made it into unofficial WhatsApp libraries which allow developers to use WhatsApp service in their applications, starting with a python-library called yowsup, and the rest will follow. It's worth mentioning that none of those libraries are supported nor approved by WhatsApp, so one has to wonder if WhatsApp is going to take some legal action (again) against them.

New App Detects Government Stingray Cell Phone Trackers 71

HughPickens.com writes IMSI catchers, otherwise known as stingrays, are those surveillance tools that masquerade as cell towers and trick mobile phones into connecting, spewing private data in the process. Law-enforcement agencies have been using them for almost two decades, but there's never been a good way for individuals to detect them. Now Lily Hay Newman reports that SnoopSnitch scans for radio signals that indicate a transition to a stingray from a legitimate cell tower. "SnoopSnitch collects and analyzes mobile radio data to make you aware of your mobile network security and to warn you about threats like fake base stations (IMSI catchers), user tracking and over-the-air updates." say German security researchers Alex Senier, Karsten Nohl, and Tobias Engel, creators of the app which is available now only for Android. The app can't protect people's phones from connecting to stingrays in the first place, but it can at least let them know that there is surveillance happening in a given area. "There's no one set of information, taken by itself, that allows you to detect an IMSI catcher," says Nohl. "But we do stream analysis of everything that happens on your phone, and can come out with a warning if it crosses a certain threshold."

Stingrays have garnered attention since a 2011 Arizona court case in which one agent admitted in an affidavit that the tool collaterally swept up data on "innocent, non-target devices" (U.S. v. Rigmaiden). The government eventually conceded in this case that the "tracking operation was a Fourth Amendment search and seizure," meaning it required a warrant. But given that the Justice Department has continued to claim that cellphone users have no reasonable expectation of privacy over their location data, it may take a Supreme Court judgement to settle the Stingray issue countrywide.

Pew Survey: Tech Increases Productivity, But Also Time Spent Working 82

An anonymous reader writes: A survey of American workers conducted by the Pew Research Center found that email was their most indispensable tool, topping even broad access to the internet. 46% of workers say their productivity has increased thanks to email, the internet, and cell phones, while only 7% say those technologies have caused it to decrease. While many workers say technology has created a more flexible work schedule, they also say it has increased the total amount of hours they spend working. Almost half of the surveyed employees say their employer either forbids or explicitly blocks access to certain websites at the office. How have these technologies affected your work environment?

Security Research At the Hague, Netherlands: Mobile Network and Internet Threats 16

MojoKid writes: The Hague Security Delta (HSD) is the official title of a collaborative effort between Netherlands businesses, their federal government and multiple research institutions, to identify emerging security threats, share best practices, and foster collaboration between industry, governments, and universities. One of the most pressing issues they're tackling is that of mobile network and internet security. One point that the Netherlands' officials made repeatedly is that the country is essentially the "digital gateway" to Europe. This might seem like hubris but once you look at the arrangement of undersea cables between the U.S. and Europe, it makes a lot more sense. The Netherlands is far from the only transatlantic connection hub between the U.S. and Europe, but it certainly accounts for a significant chunk of total cable capacity. One of the brainchildren of the HSD is the creation of what it calls the "Trusted Networks Initiative" that would allow direct denial of service attacks originating from specific countries to be cut off. By creating a network "bridge" that can be raised and lowered, the idea is that content and visitors can be cleanly isolated from the bad actors launching an attack. There's an intrinsic assumption here — specifically, the idea that attackers are gathered into a group of systems that can cleanly be split from the so-called "trusted" networks that would continue to operate. It is however, an interesting concept to thwart broad-scale DDoS attacks.

Is the Tablet Market In Outright Collapse? Data Suggests Yes 328

Nerval's Lobster writes Is the tablet market rapidly collapsing? Mobile-analytics firm Flurry doesn't come to quite that stark a conclusion, but things aren't looking too good for touch-screens that don't qualify as "phablets." According to Flurry's numbers, full-sized tablets accounted for only 11 percent of new devices in 2014, a decline from 2013, when that form-factor totaled 17 percent of the new-device market; small tablets experienced a smaller decline, falling from 12 percent to 11 percent of new devices between 2013 and 2014. (Meanwhile, phablets expanded from 4 percent of new devices in 2013 to 13 percent this year.) Boy Genius Report, for its part, looked at those numbers and decided that the tablet market is doomed: "Consumers happy with compact smartphones are not switching to larger iPhones for now, but former tablet buyers are." That's not to say people will stop using tablets, but the onetime theory that they would one day cannibalize all PCs looks increasingly nebulous.

Twitter Bug Locks Out Many Users 69

TechCrunch and ZDNet are among the many sources to report that many users are having trouble right now signing in to Twitter, and that the company is working right now to fix the glitch. As ZDNet describes the problem, According to Twitter's server response at the time of writing, most of 2015 has happened, and we are heading into a bright new 2016 in a couple of days time. Querying Twitter's HTTP response headers at https://twitter.com returns a time stamp dated one year into the future: "date: Mon, 29 Dec 2015 02:09:37 UTC". Consequently, users of Twitter's popular Tweetdeck application have experienced seeing every incoming tweet appear with a time stamp reporting the tweet to be from 365 days ago. At the same time that Twitter's servers began returning the incorrect date, some users of Twitter's official Android app were logged out of the service, and unable to log in again via the app. Users of some third-party Twitter applications have also reported being locked out of their apps.
