Google opens up on its SDN

At this week’s Open Network Summit, Google spoke for the first time publicly about its custom data center network. For nearly a decade, we’ve been hearing, reading and writing about how Google was building its own switches and writing its own software to handle the tremendous traffic load on its search engine and applications because vendor offerings were either not up to the task, too expensive, or both.This week we found out how they did it. In a keynote presentation at ONS, Amin Vahdat, Google Fellow and Technical Lead for Networking, described the company’s data center network architecture, capabilities and capacity for a rapt audience thirsting for information on software-defined networking implementations and experiences.To read this article in full or to leave a comment, please click here

Outlook for iOS, Android get enhanced management features

Microsoft updated its Outlook apps for iOS and Android Thursday to let system administrators have greater control over how employees use corporate email accounts.The update brings support for the company’s Intune mobile application management solution and a Conditional Access feature that requires users enroll in mobile device management before getting their Office 365 email through Outlook. Administrators can deploy the Outlook app to devices that are enrolled in a company’s Intune system, and then manage them under a custom policy.That policy can include a variety of limitations, like preventing users from copying corporate email content to applications or other email accounts that aren’t managed by the company and encrypting data from the Outlook app. At the same time, the profile can be set up so that personal email accounts added to the Outlook app aren’t managed under corporate policy.To read this article in full or to leave a comment, please click here

6 historic tech items that were rescued from the trash

Image by Brian Dunnette CC BY 2.0All technology, sooner or later, becomes obsolete at which point it’s often simply disposed of in one way or another and forgotten about. Sometimes that piece of technology is a one-of-kind or is historic for some other reason but its importance isn’t recognized at the time and it’s lost for good. Every once in a while, though, a historic piece of hardware or software is saved from such an inglorious fate through the hard work of those who appreciate its historic value or thanks simply to dumb luck. Use the arrows above to read about 6 historic tech items that were literally pulled out of a dumpster, landfill, or recycling center - or were rescued just before they made it into one.To read this article in full or to leave a comment, please click here

Go has a debugger—and it’s awesome!

Something that often, uh... bugs1 Go developers is the lack of a proper debugger. Sure, builds are ridiculously fast and easy, and println(hex.Dump(b)) is your friend, but sometimes it would be nice to just set a breakpoint and step through that endless if chain or print a bunch of values without recompiling ten times.

You could try to use some dirty gdb hacks that will work if you built your binary with a certain linker and ran it on some architectures when the moon was in a waxing crescent phase, but let's be honest, it isn't an enjoyable experience.

Well, worry no more! godebug is here!

godebug is an awesome cross-platform debugger created by the Mailgun team. You can read their introduction for some under-the-hood details, but here's the cool bit: instead of wrestling with half a dozen different ptrace interfaces that would not be portable, godebug rewrites your source code and injects function calls like godebug.Line on every line, godebug.Declare at every variable declaration, and godebug.SetTrace for breakpoints (i.e. wherever you type _ = "breakpoint").

I find this solution brilliant. What you get out Continue reading

Anger

"

I suppose that when one hears a tale of hideous cruelty anger is quite the wrong reaction, and merely wastes the energy that ought to go in a different direction: perhaps merely dulls the conscience which, if it were awake, would ask us, “Well, what are you doing about it? How much of your live have you spent in really combating this?”

Samsung wants court to review damages in patent fight with Apple

Samsung Electronics has asked that a full bench of an appeals court should review a damages award in a long-standing patent infringement dispute with arch-rival Apple.Apple sued Samsung in 2011 alleging that Samsung phones infringed on several iPhone patents. The U.S. District Court for the Northern District of California awarded Apple damages of US$930 million after a jury found that Samsung infringed Apple’s design and utility patents and diluted its trade dresses, which relate to the overall look and packaging of a product.A three-judge panel of the U.S. Court of Appeals for the Federal Circuit agreed last month with the jury’s verdict on the design patent infringements, the validity of two utility patent claims, and the damages awarded for the design and utility patent infringements appealed by Samsung. But the appeals court reversed the jury’s findings that the asserted trade dresses are protectable, and vacated the damages relating to trade dress dilution.To read this article in full or to leave a comment, please click here

LinkedIn says private bug bounty program works for it better

LinkedIn plans to continue closely vetting researchers for its bug bounty rewards program, saying it reduces the number of distracting erroneous and irrelevant reports.The decision to keep its program private “gives our strong internal application security team the ability to focus on securing the next generation of LinkedIn’s products while interacting with a small, qualified community of external researchers,” wrote Cory Scott, LinkedIn’s director of information security, in a blog post.Security researchers with vetted backgrounds are invited to participate, which allow them to have the same experience as if they were on LinkedIn’s internal security team, Scott wrote.To read this article in full or to leave a comment, please click here

Oracle profit slides 24 percent as customers move to the cloud

Oracle has reported a sharp drop in profit for the quarter just ended, with customers spending more on its cloud services but less on software that runs in their own data centers.Chairman Larry Ellison portrayed the shift as a positive one and said Oracle can make more money selling cloud services over the long term. But the change didn’t seem to help it much last quarter, when its results were also battered by the strong U.S. dollar.Oracle’s revenue and profit for the quarter, the fourth of its fiscal year, missed the forecasts of financial analysts, and its stock fell almost 7 percent after the results were announced Wednesday.Oracle’s cloud business seems to be growing strongly. Revenue from software sold as a service climbed 29 percent from this time last year, to $416 million, the company said. But that’s a relatively small part of Oracle’s business, and it wasn’t enough to offset mediocre performance elsewhere.To read this article in full or to leave a comment, please click here

FCC to AT&T: “Unlimited means unlimited”

AT&T Mobility, in common with many other service providers of all kinds, uses the word “unlimited” to describe their consumer wireless data offerings. Unfortunately, for consumers, AT&T is using a totally different definition of the word because to the company, “unlimited” has meant “until you reach a threshold of service usage after which we’ll throttle back your performance.”The FCC, in their usual slow and lumbering way, has finally got around to doing something about this blatant and devious redefinition of “unlimited” (it’s taken them four, count ‘em, four years) and proposes to fine AT&T … wait for it … a record $100 million for misleading customers on the grounds that the company violated the 2010 Open Internet Transparency Rule that required ISPs to clearly and transparently inform their customers about their network management practices.To read this article in full or to leave a comment, please click here
