Worth Reading: Radicalizing data collection

Like many Silicon Valley start-ups, Larry Gadea’s company collects heaps of sensitive data from his customers. Recently, he decided to do something with that data trove that was long considered unthinkable: He is getting rid of it. The reason? Gadea fears that one day the FBI might do to him what it did to Apple in their recent legal battle: demand that he give the agency access to his encrypted data. Rather than make what he considers a Faustian bargain, he’s building a system that he hopes will avoid the situation entirely. Washington Post

NASA describes out of this world data glitch that almost finished its planet hunter

NASA’s highly successful Kepler space telescope has had more than its share of near fatal experiences.The latest happened in April when the spacecraft went into “Emergency Mode” which among other things allows for priority access to ground-based communications via NASA’s Deep Space Network. NASA noted at the time that the spacecraft is nearly 75 million miles from Earth, making the communication slow. Even at the speed of light, it takes 13 minutes for a signal to travel to the spacecraft and back.The spacecraft has since returned to normal function.To read this article in full or to leave a comment, please click here

Industrial control systems vendors get careless about domain squatting

Many companies protect their brands by registering domain names that are slight variations on their own, but manufacturers of industrial control systems don't seem to have followed suit, potentially leaving customers open to attack.Researchers from security consultancy Digital Bond have found 433 so-called "squat" domains whose names are similar to those of 11 industrial manufacturers, and which have been registered by unknown third parties. Some of the domains have been hosting scams, malicious redirects and malware.Attackers engage in domain squatting for various reasons: to host phishing pages in order to steal credentials, direct accidental visitors to malware, profit from the brand's popularity by displaying ads, or sell the domain to the brand owner for a large fee.To read this article in full or to leave a comment, please click here

Silicon Choices

Cumulus Networks has always strived to provide our customers with choice. And now, Cumulus Linux 3.0 has been refactored to make the user experience fun and easy … and at the same time bring you, even more choice:

  • In hardware platforms, from a variety of manufacturers.
  • In CPU architectures — x86 and ARM.
  • In Broadcom networking chips for a variety of use cases — 1G, 10G, 10GBase-T, 40G and 100G switches with Helix4, Hurricane2, Trident-II, Trident-II+ or Tomahawk chips inside.
  • And now, for the first time, choice in silicon vendors with the introduction of Cumulus Linux-powered 40G and 100G switches with Mellanox Spectrum chips inside.

Shrijeet Mukherjee (our fearless engineering leader) kicked off the Cumulus Linux 3.0 development cycle with this as our main goal — to offer even more choice to our customers. And then this happened…

three-dragons

 

So we took on the challenge of unifying the user experience across this sweeping range of hardware platforms and switch silicon without muting the unique prowess and feature richness of any of them.

How did we do this? By deploying the three dragons in our arsenal: ONIE, switchd and the Linux kernel itself (which is now better fed by Continue reading

Lenovo wants consumers to take Google Tango for granted, so does Google

Gamers and R&D labs creating new applications for augmented reality (AR) and virtual reality (VR) have been the source of enthusiasm for this new category. But most people have only a superficial opinion—or no opinion—about these exciting emergent technologies because they haven’t become relevant in their lives. The two early use cases, games and immersive 360-degree video, represent large future businesses that few people have experienced.Yesterday, Lenovo introduced the Phab2 Pro, which is both an AR device and has all the features of an Android smartphone. It’s a more approachable form of AR because the consumer looks through the Phab2 Pro like a looking glass and doesn’t feel awkward donning a strange-looking headset or visor. It feels normal—like taking a picture or video.To read this article in full or to leave a comment, please click here

3 ways to improve security as you embrace containers

This vendor-written tech primer has been edited by Network World to eliminate product promotion, but readers should note it will likely favor the submitter’s approach.In enterprise IT, disruptive technologies become commercially viable faster than you can say “Moore’s Law.”  However, if corporate culture and processes don’t evolve in conjunction with the pace of technology, it can inhibit the benefits of even the most awesome of enterprise apps. One area of IT where corporate culture has stymied progress is cyber security, but the rise of software containers — arguably one of the most disruptive enterprise technologies on the horizon - provides an opportunity to get application security right, or at least make it a whole lot better.To read this article in full or to leave a comment, please click here

Intralinks adds security layers for high value content collaboration using SharePoint and other systems  

This column is available in a weekly newsletter called IT Best Practices.  Click here to subscribe.   Recently I was engaged by a large corporation for a writing project to support a product launch. This project had a small team of people who needed to collaborate on developing some promotional materials using content that had to remain confidential until launch day.The company was so protective of the content's secrecy that it provided me with a company-issued laptop computer, VPN access to their network, and a login ID for their network. In particular, I was given behind-the-firewall access to the SharePoint repository where the in-progress documents were kept. This way I was fully integrated into the internal team for the duration of the project, and the confidential documents would never have to leave the safety of the company's network.To read this article in full or to leave a comment, please click here

IDG Contributor Network: The IoT market is unlikely to create a gorilla

In his book The Gorilla Game, management consultant Geoffrey Moore identifies a tendency for some technology sectors to develop winner-take-all outcomes. The Internet of Things (IoT) market looks like a textbook example, as many industrial customers (original equipment manufacturers) are looking to consolidate around a single platform, a slice of enabling technology. It is surprising, therefore, that no IoT gorilla has yet emerged from the mist.+ More on Network World: Most powerful Internet of Things companies +To read this article in full or to leave a comment, please click here

Cracked spoofs wireless carriers’ ads

It's open season on wireless carriers' silly and confusing commercials.Sure, Verizon, AT&T, Sprint & T-Mobile have been the butt of jokes for some time now, and justifiably so, for the flimflam they spew about their amazing speeds and bargain pricing. SNL, for example, skewered Verizon a few years back in a skit that depicted all the jargon spewed by Verizon as "an old person's nightmare."Comedy Central's Amy Schumer more recently sent up those mobile phone ads that feature perky young women interacting with customers.To read this article in full or to leave a comment, please click here
