This startup promises a better way to buy or sell a used car

Who wants to buy a used car through eBay or Craigslist, when you need a mechanic to inspect it? Buying through a dealer can also be intimidating and expensive, with sales reps often having unclear agendas.Shift, an online startup, thinks it can solve those problems, and provide an easier way for people to sell their cars.The company provides a listing service for used car shoppers to browse other people’s cars, and let owners list their cars for sale. But more than a listing service, the company employs mechanics to perform inspections on cars for sale, and hires workers to gather sellers’ service records and vehicle history reports. Shift’s workers will also deliver used cars to prospective buyers for test rides, within an hour.To read this article in full or to leave a comment, please click here

Video: Implementing VLAN-aware Bridge with OpenFlow

Reinventing the wheels makes little sense. Implementing old solutions with new tools might be in the same category, but at least it shows you the power and shortcomings of the new tools.

Building a VLAN-aware bridge in OpenFlow is thus a mandatory case study, and as you’ll see in the video from the OpenFlow Deep Dive webinar, it’s not as easy as it looks. For more details, watch the whole OpenFlow webinar (6 hours of in-depth videos), which you also get by buying Advanced SDN Training or ipSpace.net subscription.

AMD to launch next-generation Fiji GPUs on June 16

Gamers, buckle up—AMD will launch its highly-anticipated graphics processing unit, code-named Fiji, on June 16 at the E3 conference.Many were expecting Fiji to launch at a press event at Computex on Wednesday, but that didn’t happen. Instead, AMD did show off key technology, which will first appear in Fiji and could give significant speed and power saving gains to future graphics chips.On stage, AMD CEO Lisa Su showed a chip for technology called HBM (high-bandwidth memory), which could make graphics chips faster and more power-efficient.HBM offers 3.5 times the bandwidth per watt of GDDR5, which is currently used in memory chips. Instead of being placed next to each other, HBM stacks memory chips, which are connected through a high-speed thread. HBM is also faster due a wider bus and its closer location to graphics processors.To read this article in full or to leave a comment, please click here

Comcast and TWC are (still) among the most hated companies in America

The annual American Customer Satisfaction Index for 2015 placed Comcast and Time-Warner Cable near the very bottom of all telecom and technology companies in the rankings, the researchers involved announced Tuesday.The ACSI’s ratings – on a 100-point scale – gave Comcast a score of 54 as a TV service provider and 56 as an ISP, well below the industry average of 63 in both categories. TWC received a 51 in the former category and a 58 in the latter. The ratings were based on the ACSI’s in-house analysis of survey responses from 14,000 Americans, which were collected during the first quarter of 2015.+ ALSO ON NETWORK WORLD: Ransomware creator apologizes for 'sleeper' attack, releases decryption keys + Intel to buy Altera for $16.7B, eyes IoT market +To read this article in full or to leave a comment, please click here

AMD skips Chromebooks, bets on Windows 10 with new Carrizo chips

Chromebooks may be hot-ticket items, but with its sixth-generation A-series chips for mainstream laptops, AMD is placing its bets on Microsoft’s Windows 10.The new chips, code-named Carrizo, will appear in laptops priced between US$400 and $800 from Asus, Acer, Lenovo, Hewlett-Packard and Toshiba. The first wave of laptops will become available starting in July, initially with Windows 8, and later in the year with Windows 10.The new chips include quad-core A8 and A10 processors, which have up to six GPU cores, and the faster FX chips, which have up to eight GPU cores. Some new laptops based on the chips were shown at the Computex trade show in Taipei this week.To read this article in full or to leave a comment, please click here

Facebook mandates stronger digital verification of apps

Facebook will require application developers to move later this year to a more secure type of digital signature for their apps, which is used to verify a program’s legitimacy.As of Oct. 1, apps will have to use SHA-2 certificate signatures rather than ones signed with SHA-1. Both are cryptographic algorithms that are used to create a hash of a digital certificate that can be mathematically verified.Apps that use SHA-1 after October won’t work on Facebook anymore, wrote Adam Gross, a production engineer at the company, in a blog post.“We recommend that developers check their applications, SDKs, or devices that connect to Facebook to ensure they support the SHA-2 standard,” Gross wrote.To read this article in full or to leave a comment, please click here

Google-backed Magic Leap opens up to third-party developers

Magic Leap, the mysterious startup backed by Google that is developing a headset for augmented reality, wants outside help to create content for its device.On Tuesday, the company said it would be opening its platform to third-party developers with an SDK (software development kit) that would let developers create content for Magic Leap’s system.Magic Leap has developed what it calls a photonics light field chip, which would project 3D images directly on people’s eyes and superimpose those images over what users see in the real world. It’s designed to be superior to stereoscopic vision, which uses two different images to trick the eye into thinking something is 3D. Magic Leap thinks this “augmented” content could take any number of forms, for applications in gaming but also in storytelling and communications.To read this article in full or to leave a comment, please click here

Uh, the only reform of domestic surveillance is dismantling it

A lot of smart people are cheering the reforms of domestic surveillance in the USA "FREEDOM" Act. Examples include  Timothy Lee, EFF, Julian Sanchez, and Amie Stepanovich. I don't understand why. Domestic surveillance is a violation of our rights. The only acceptable reform is getting rid of it. Anything less is the moral equivalent of forcing muggers to not wear ski masks -- it doesn't actually address the core problem (mugging, in this case).

Bulk collection still happens, and searches still happen. The only thing the act does is move ownership of the metadata databases from the NSA to the phone companies. In no way does the bill reform the idea that, on the pretext of terrorism, law enforcement can still rummage through the records, looking for everyone "two hops" away from a terrorist.

We all know the Patriot Act is used primarily to prosecute the War on Drugs rather than the War on Terror. I see nothing in FREEDOM act that reforms this. We all know the government cloaks its abuses under the secrecy of national security -- and while I see lots in the act that tries to make things more transparent, the act still Continue reading

Oracle brings Ghostery into Marketing Cloud to help users monitor their websites

The average company has about 70 different types of third-party code on its website but is aware of only about a third of them. The rest are hidden in services like ad networks, widgets and analytics tools, and they can bog down performance, threaten security and compromise search-engine optimization.That’s according to Ghostery, which on Tuesday announced a partnership with Oracle whereby its TrackerMap Live monitoring tool is now available to users of the Oracle Marketing Cloud. Offered on the Oracle Marketing AppCloud, TrackerMap Live is designed to help reveal the interconnected ecosystem of code and third-party tags on company websites.Using TrackerMap Live, companies can pinpoint where each tag on their site comes from and see what its effects are. Along the way, they can determine whether vendors are placing unwanted or non-secure piggyback tags on their website without permission.To read this article in full or to leave a comment, please click here

IPv6 DMVPN Routing

In our last article we looked at IPv6 over IPv4 DMVPN configuration, where IPv4 transport was used to tunnel IPv6 traffic. In this blog post I would like to show you how to deploy pure IPv6 DMVPN network, and even more importantly, how to enable one IPv6 Routing Protocol over another in the Cloud.

Since IPv6 will be now also used as the underlying transport, the overall configuration of the DMVPN devices will be a little bit different from the previous example; also note that our topology was slightly modified :

IPv6-DMVPN-20

Key thing here is that NBMA addresses are no longer IPv4; basically IPv6 is used everywhere, which means that our mappings on the Spokes will be always referring to v6 information.

Let’s start our configuration. We will first configure our Hub (R3), then the Spokes (R2, R4), and finally enable routing on the Overlay network. Since IPSec is optional, we will not be using it in this example (note that to protect IPv6 packets IKEv2 would have to be used, not IKEv1).

R3 (Hub) configuration. Again, everything is IPv6, including the tunnel mode. Don’t forget that link-local addresses must be always hard-coded on a given Cloud, on every device Continue reading

Senate passes bill to rein in NSA phone dragnet

The U.S. Senate has passed legislation intended to rein in the National Security Agency’s bulk collection of domestic telephone records, sending the bill to President Barack Obama for his signature.The Senate’s 67-32 vote Tuesday on the USA Freedom Act restores a limited telephone records program at the NSA to resume after the old bulk collection program expired Sunday night. After Obama’s signature, the NSA will have six months to transition its phone records database to U.S. telecom carriers.The USA Freedom Act, aimed at ending bulk collection of telephone records, was needed after revelations about the program by former NSA contractor Edward Snowden in mid-2013, supporters said. Some digital rights groups have blasted the bill as “fake reform,” but the bill’s limits on the NSA will help restore the U.S. public’s trust in government surveillance efforts, said Senator Patrick Leahy, a Vermont Democrat and sponsor of the bill.To read this article in full or to leave a comment, please click here

Faster Wi-Fi is coming soon to a device near you

Wi-Fi in your home or office could get a big speed boost by the end of this year with Qualcomm's newest chip, which reaches new highs in data transfer speeds.The peak wireless data transfer speeds of the QCA9994 and QCA9984 Wi-Fi chips will reach 1.7G bps (bits per second). That speed can be achieved through single or multiple data streams from devices on an 802.11ac Wi-Fi network.MORE: Full speed ahead for 802.11ac WiFiThe speed tops Qualcomm's previous high of around 1Gbps, which it achieved in products released last year. To put the wireless speed in perspective, the data transfer speeds of a wired USB 3.0 connection peaks at 5Gbps, which in most cases is considered adequate for external hard drives.To read this article in full or to leave a comment, please click here
