College kids to the rescue with IT support startup HelloTech

Not that Baby Boomers or Gen X homeowners are clueless about technology, but startup HelloTech is banking on people of a certain age needing a bit of assistance to live the Internet of Things dream.The West Los Angeles startup this week announced it has added $2 million in venture funding to the $2.5 million it attracted last fall to expand the on-demand, in-home tech support service that it officially rolled out this week in LA.CEO Richard Wolpert, a 4-time startup founder whose background includes stints as president of Disney Online and chief strategy officer at RealNetworks, says the need for HelloTech has been borne out of the explosion of new and useful home technologies and the decline in retail tech outlets (aside from Best Buy and its Geek Squad) that offer tech installation/support.To read this article in full or to leave a comment, please click here

Google’s Project Brillo is an OS for the home — and a lot more

Google has made a big play for the Internet of Things, announcing a new OS on Thursday that will connect appliances around the home and allow them to be controlled from an Android smartphone or tablet.Dubbed Project Brillo, it’s a stripped down version of Google’s Android OS that will run on door locks, ovens, heating systems and other devices that have a small memory footprint, and allow them to communicate and work together.Project Brillo also includes a communications layer, called Weave, that provides a common language developers can use to locate devices on a network and tap into their capabilities, said Sundar Pichai, Google senior vice president, who announced the system at Google’s I/O conference in San Francisco.To read this article in full or to leave a comment, please click here

Google takes another swing at payments with Android Pay

Google is overhauling its approach to mobile payments with Android Pay, which will let people use their smartphone to make payments in brick and mortar stores as well as in apps like Lyft and GrubHub.The changes are an effort by Google to reclaim momentum in the area of mobile payments, where Apple Pay has been fast taking hold and other rivals like Samsung’s LoopPay are emerging.Android Pay will be incorporated into the next version of Android, currently known as Android M, which was unveiled at Google’s I/O conference for developers in San Francisco Thursday. The service will also work with previous versions of Android as far back as KitKat, said Dave Burke, VP of engineering at Google.To read this article in full or to leave a comment, please click here

FCC proposal would extend Lifeline voice subsidy to broadband

The U.S. Federal Communications Commission will consider including broadband within a controversial program that subsidizes telephone or mobile service for poor people.Recipients of the FCC’s Lifeline program, which provides a US$9.25 monthly subsidy for voice service, could use that money to purchase broadband service instead under a proposal from FCC Chairman Tom Wheeler. Eligible households would continue to receive one $9.25 monthly subsidy, and they could choose whether to apply the money to traditional telephone service, mobile service or broadband, FCC officials said Thursday.To read this article in full or to leave a comment, please click here

Like routers, most USB modems also vulnerable to drive-by hacking

The majority of 3G and 4G USB modems offered by mobile operators to their customers have vulnerabilities in their Web-based management interfaces that could be exploited remotely when users visit compromised websites.The flaws could allow attackers to steal or manipulate text messages, contacts, Wi-Fi settings or the DNS (Domain Name System) configuration of affected modems, but also to execute arbitrary commands on their underlying operating systems. In some cases, the devices can be turned into malware delivery platforms, infecting any computers they’re plugged into.Russian security researchers Timur Yunusov and Kirill Nesterov presented some of the flaws and attacks that can be used against USB modems Thursday at the Hack in the Box security conference in Amsterdam.To read this article in full or to leave a comment, please click here

Lenovo aims at toppling rivals in the server market

Following its IBM x86 server business acquisition, Lenovo plans on attacking the enterprise hardware arena with low-cost products to undercut the competition.“We can give a better cost solution to enterprise companies,” said Lenovo Executive Vice President Gerry Smith in a press briefing in Beijing Thursday.The Chinese vendor is preparing to offer a wide range of products, targeting markets including supercomputing and hyperscale servers for data centers. “We’re going to play in every segment,” Smith said.Lenovo last year bought IBM’s x86 server business as a way to drive company growth. The deal helped make the Chinese vendor the world’s fourth largest server vendor in this year’s first quarter, with a 7.5 percent share, according to research firm IDC. A year ago, Lenovo had only a 1.1 percent share.To read this article in full or to leave a comment, please click here

Design Considerations for North/South Flows in the Data Center

Traditional data centers have been built by using standard switches and running Spanning Tree (STP). STP blocks redundant links and builds a loop-free tree which is rooted at the STP root. This kind of topology wastes a lot of links which means that there is a decrease in bisectional bandwidth in the network. A traditional design may look like below where the blocking links have been marked with red color.

DC1-STP

If we then remove the blocked links, the tree topology becomes very clear and you can see that there is only a single path between the servers. This wastes a lot of bandwidth and does not provide enough bisectional bandwidth. Bisectional bandwidth is the bandwidth that is available from the left half of the network to the right half of the network.

DC2-STP

The traffic flow is highlighted below.

DC3-Bisectional

Technologies like FabricPath (FP) or TRILL can overcome these limitations by running ISIS and building loop-free topologies but not blocking any links. They can also take advantage of Equal Cost Multi Path (ECMP) paths to provide load sharing without doing any complex VLAN manipulations like with STP. A leaf and spine design is most commonly used to provide for a high amount Continue reading

Cellphone use involved in more than 1 in 4 car crashes

Cellphone-related car crashes were up for the third straight year in the United States and now account for more than one in four crashes, according to the National Safety Council.The nonprofit council created by Congress in 1913, a few years before cellphones came onto the scene, has based its latest report on crash stats from 2013. Its numbers involve crashes involving drivers who are texting or talking on either handheld or hands-free phones.  The Council estimates texting-related crashes rose from 5% to 6% while those involving talking on phones stayed at 21%, for a total of 27% of the 5.7 million crashes in 2013.To read this article in full or to leave a comment, please click here
