Flutter: A $20 wireless Arduino with a long reach

Flutter A $20 wireless Arduino with a long reach

If the words “ARM-powered wireless Arduino” send your heart aflutter, then you might be interested in… Flutter — a development platform with the aforementioned qualities. The Kickstarter project claims the device has a usable range of over half a mile, letting you nail that wireless letterbox-checker project with ease. Similar tools, such as Xbee and Zigbee already exist, but the $20 price tag for the Flutter basic, and $30 for Flutter Pro (adds battery charging, another button, more memory) make this a tempting option for tinkerers on a budget. So, if building that mesh network of quadrocopters has been sitting at the top of your to-do list for too long, we recommend you get backing right now.

DARPA’s private internet and cloud for soldiers shows promise in the field

DARPA CBMEN private internet

Sure, we hear about DARPA’s robots all the time, but they’re not the only things keeping the agency busy. Take CBMEN, for example — a DARPA project that’s goal is to create a private ad-hoc data network for the military, and it’s recently completed initial field testing. CBMEN, or Content-Based Mobile Edge Networking, allows soldiers to share images and other info without a traditional mobile internet connection. Each device loaded with the CBMEN software will automatically blast data to other hardware within reach via WiFi, cellular and radio frequencies — no intermediate infrastructure required. Early trials of the tech using Android smartphones and Army Rifleman Radios were deemed successful. We don’t know if CBMEN will ever be available to civilians, but seeing as DARPA mentioned its potential use in disaster response operations, it’s not entirely impossible. Before anyone else can test drive the nebulous network, though, it first has to ace the second phase of field testing that aims to make it more efficient and secure.

LinkedIn launches University Pages, helps students learn more about colleges

LinkedIn launches University Pages, helps students learn more about colleges

LinkedIn has already branched out a bit with its own blogging and following features for select groups, and now the popular social networking site has introduced a tool geared towards students. Aptly dubbed University Pages, LinkedIn describes the new service as one that’s part of its strategy to help college-bound pupils “at every critical milestone from campus to fulfilling successful careers.”

Beginning September 12th, LinkedIn’s set to welcome high school students on its network and provide access to the new University Pages, allowing them to explore and rub elbows with about 200 participating universities, both in the US and abroad. Users will then be able to do things such as receive regular updates about campus news / activities and view notable members of each college’s alumni. If one of your favorite schools isn’t there just yet, fret not — LinkedIn says “thousands more” will be given access over the next few weeks.

Connecting Cape Town: Inside South Africa’s TV white spaces experiment

Connecting Cape Town Inside South Africas TV white spaces experiment

In 2011, a United Nations commission came to a powerful conclusion: access to broadband internet is a basic human right, matched by the likes of housing, sustenance and healthcare. Arguments can be made that widespread access has transformed entire economies while kick-starting others, with Finland even going so far as to command its ISPs to provide 1 Mbps connections to all homes regardless of location. Both the United States and the United Kingdom have similarly ambitious plans, and all three of these countries have one particular catalyst in common: funds.

The harsh reality, however, is the economies that stand to gain the most from sweeping internet adoption are also the least equipped to enable it. In early 2010, the European Bank estimated that a project to roll out passive optical fiber to 33 cities in the Netherlands would cost nearly €290 million. The mission driving such funding? “To stimulate innovation and keep Europe at the forefront of internet usage.” It’s the answer to a problem that could undoubtedly be categorized as “first world,” but consider this: Internet World Stats found that 92.9 percent of The Netherlands’ population routinely used the world wide web in 2012. Let’s just say it’s easier to invest in an initiative that you’re certain nearly 9 in 10 citizens will use.

In the whole of Africa, just 15.6 percent of residents are connected to the internet, which is under half of the world average. It’s also home to vast, inhospitable landscapes that are economically inviable to crisscross with fiber. All of that being said, nearly a sixth of the globe’s population resides on the continent, representing a monumental opportunity for something — anything — to connect the next billion people. As it turns out, there are actions presently ongoing to make a significant mark in the course of history. Google, Microsoft, Carlson Wireless, Tertiary Education and Research Network of South Africa (TENET) and a host of other powerful entities are collaborating to bring high-speed internet to an underserved continent via TV white spaces — a low-cost, highly adaptable technology that’s poised to explode. For now, Cape Town, South Africa, is acting as a proving ground for what will eventually be a far larger experiment. The core goal is actually quite simple: to beam hope to a disconnected society, with unused bands between TV channels acting as the medium. %Gallery-slideshow67067%

HDBaseT 2.0 spec makes the all-in-one home theater cable better, cheaper

We haven’t checked on the HDBaseT Alliance in a few years, but now its 5-in-1 Ethernet cable spec is getting a second revision. HDBaseT already crams virtually any HD source and signal — and power! — into one connection, and 2.0’s biggest addition to the mix is USB 2.0 support. Manufacturers can now remove the multiple interfaces and conversion components the previous spec required, driving down prices and requirements for hardware like Pioneer’s $3,000 A/V receiver. Beyond that, this new version brings control point-capability and networking into its single cable-party. Until now, this tech has been aimed primarily at professional installers and dedicated enthusiasts, but the new spec’s focus on user friendliness and lower cost could bring more of us to the whole-house media bandwagon. Finally, surround sound for the bathroom delivered by a single network cable is within our reach.

Leaked NSA audit shows privacy violations in cellular and fiber optic surveillance

NSA seal

The NSA insists that it respects American privacy, but documents leaked by Edward Snowden to the Washington Post suggest that the agency has trouble maintaining that respect. A May 2012 audit, buried in the documents, 2,776 incidents where the NSA’s Washington-area facilities inadvertently obtained protected American data through a mix of human errors and technical limits. Among its larger gaffes, the NSA regularly had problems determining when foreign cellphones were roaming in the US, leading to unintentional snooping on domestic calls. The agency also spent months tapping and temporarily storing a mix of international and domestic data from US fiber lines until the Foreign Intelligence Surveilliance Court ruled that the technique was unconstitutional. NSA officials responding to the leak say that their agency corrects and mitigates incidents where possible, and argue that it’s difficult for the organization to avoid errors altogether. However, the audit also reveals that the NSA doesn’t always report violations to overseers — the division may be interested in fixing mistakes, but it’s not eager to mention them.

Intel teases MXC: a 1.6Tbps optical interconnect for servers

Intel teases MXC a 16Tbps, optical interconnect for servers

While we think of optical connections as cutting edge, they’re positively decrepit in server rooms; current fiber interconnect technology got its start in the 1980s. Intel may soon drag servers into the modern era with its just-teased MXC format, however. The standard (not pictured here) will combine both silicon photonics and a new form of Corning fiber to link servers at 1.6Tbps — more than quick enough to eliminate many data bottlenecks. The connectors themselves are smaller, too. Intel won’t say more about MXC until the Intel Developer Forum next month in San Francisco, but we already suspect that supercomputer operators will be happy with all that extra bandwidth.

FCC loosens outdoor power restrictions on 60GHz spectrum

DNP FCC loosens restrictions on 60 GHz spectrum, could enable cheap rural broadband

In response to industry petitioners, the FCC is easing outdoor power restrictions on the unlicensed 60GHz spectrum, which could bring faster broadband to rural areas and cost-effective backhaul solutions in urban settings. This ruling change would permit outdoor devices to deliver high-speed data over greater distances — around a mile at 7 Gbps, all told — and “enhance” the unlicensed utility of the 57-64GHz spectrum. While this is the same frequency WiGig uses, indoor power restrictions haven’t changed any. Because this spectrum is unlicensed, it means that basically anyone can use it as long as they follow the FCC’s rules; no funny business, please.

FreedomPop jumps to LTE, lets you run out of free data faster than ever

FreedomPop jumps to LTE, lets you run out of free data faster than ever

FreedomPop’s namesake free data hasn’t been especially fast given its reliance on WiMAX and EV-DO, but the company is taking a big step forward with just-launched support for Sprint’s LTE network. Those who buy the $149 FreedomSpot 5580 LTE hotspot (pictured above) can get truly high speeds without having to pay a cent for regular service. Future devices and LTE-friendly smartphone service are also coming, although there is a big catch. That free tier is still capped at 500MB per month — take full advantage of LTE and you’re more likely to either pay overage fees or switch to one of FreedomPop’s paid plans. Even so, the upgraded service may be tempting for those who aren’t willing to sacrifice performance at any price.
