Google has a new chip that makes machine learning way faster

Google has taken a big leap forward with the speed of its machine learning systems by creating its own custom chip that it's been using for over a year. The company was rumored to have been designing its own chip, based partly on job ads it posted in recent years. But until today it had kept the effort largely under wraps. It calls the chip a Tensor Processing Unit, or TPU, named after the TensorFlow software it uses for its machine learning programs. In a blog post, Google engineer Norm Jouppi refers to it as an accelerator chip, which means it speeds up a specific task.To read this article in full or to leave a comment, please click here

Congrats to Neil Moore – **NINE TIME** CCIE & CCDE!

Congratulations to Neil Moore on passing the CCDE Practical Exam this week, and becoming a NONTUPLE (9x) CCIE & CCDE!

Neil was a student in both my CCIE Data Center Bootcamp and CCDE Bootcamp within the past few years, and is truly an inspiration to us all. Neil’s brother Kelly is also a CCIE in Data Center. Neil likes to introduce himself and his brother to people at Cisco Live that they have 9 CCIEs between the two of them! ;) This year Neil gets to bump that up to 10 CCIEs and CCDE between the two of them!

Neil for sure will win the longest badge this year at Cisco Live 2016 Las Vegas!

Neil currently works for VMWare as an NSX Systems Engineer, is a VMware Certified Implementation Expert — Network Virtualization (VCIX-NV), and has plans to pursue the VMware Certified Design Expert (VCDX).

Congrats Neil!

Technology betrays everyone

Kelly Jackson Higgins has a story about how I hacked her 10 years ago, by sniffing her email password via WiFi and displaying it on screen. It wasn't her fault -- it was technology's fault. Sooner or later, it will betray you.

The same thing happened to me at CanSecWest around the year 2001, for pretty much exactly the same reasons. I think it was HD Moore who sniffed my email password. The thing is, I'm an expert, who writes tools that sniff these passwords, so it wasn't like I was an innocent party here. Instead, simply opening my laptop with Outlook running the background was enough for it to automatically connect to WiFi, then connect to a POP3 server across the Internet. I thought I was in control of the evil technology -- but this incident proved I wasn't.

By 2006, though, major email services were now supporting email wholly across SSL, so that this would no longer happen -- in theory. In practice, they still left the old non-encrypted ports open. Users could secure themselves, if they tried hard, but they usually weren't secured.

Today, in 2016, the situation is much better. If you use Yahoo! Mail Continue reading

Got privacy? If you use Twitter or a smartphone, maybe not so much

The notion of online privacy has been greatly diminished in recent years, and just this week two new studies confirm what to many minds is already a dismal picture.First, a study reported on Monday by Stanford University found that smartphone metadata -- information about calls and text messages, such as time and length -- can reveal a surprising amount of personal detail.To investigate their topic, the researchers built an Android app and used it to retrieve the metadata about previous calls and text messages -- the numbers, times, and lengths of communications -- from more than 800 volunteers’ smartphone logs. In total, participants provided records of more than 250,000 calls and 1.2 million texts.To read this article in full or to leave a comment, please click here

Microsoft releases ‘service pack 2’ for Windows 7

One of the most vexing aspects of a Windows 7 reinstall is that even after you install the operating system and Service Pack 1, you can expect to spend a ridiculous amount of time applying patches that came post-SP1. Service Pack 1 came out in 2011, and there have been dozens and dozens of fixes over the past five years.For the longest time, this was a sore spot among users. That and the fact that Microsoft was reluctant to issue a second service pack with just a rollup of current fixes.Well, that wish has been granted. The company today announced a "convenience rollup" for Windows 7 Service Pack 1 and Windows Server 2008 R2 that contains all of the security and non-security updates it has issued for the two operating systems since the Windows 7 Service Pack up through April 2016.To read this article in full or to leave a comment, please click here

IDG Contributor Network: Twitter location data reveals users’ homes, workplaces

Geographic location stamps transmitted in tweets can provide enough information for people to deduce where a Twitter user lives and works, say researchers. The deduction occurs through the clustering of the posting locations. The assemblage provides location patterns that provide a good guess as to where the poster spends most of his or her time. When that’s coupled with other data, such as the time of day, non-scientists recruited for the study simply picked out the homes and workplaces of the tweeters, said researchers from MIT and Oxford University in a press release.To read this article in full or to leave a comment, please click here

Climate Research Pulls Deep Learning Onto Traditional Supercomputers

Over the last year, stories pointing to a bright future for deep neural networks and deep learning in general have proliferated. However, most of what we have seen has been centered on the use of deep learning to power consumer services. Speech and image recognition, video analysis, and other features have spun from deep learning developments, but from the mainstream view, it would seem that scientific computing use cases are still limited.

Deep neural networks present an entirely different way of thinking about a problem set and the data that feeds it. While there are established approaches for images and …

Microsoft’s sale of feature phone biz erodes smartphone commitment

Microsoft today continued to undo its disastrous 2014 acquisition of Nokia's phone business, announcing that it is exiting the feature phone market, which it had once trumpeted as a critical component of its mobile strategy.The sale of its feature phone business for $350 million prompted analysts to again question Microsoft's commitment to smartphones. "There won't be any more Lumia [smartphones]," said Jan Dawson, chief analyst at Jackdaw Research, in an email reply to Computerworld's questions today. "It does leave the door open for a new, narrower, phone strategy in the future."MORE ON NETWORK WORLD: 10 (FREE!)

The Martian author Andy Weir calls for massive new space station to prep humans for Mars trip

When it comes to living on Mars, the human body is simply not suited to living for long periods in zero-g. Until this issue is solved, we have no hope of landing humans on the surface of Mars, nor can we create permanent residences in space.That was the crux of the testimony given to the House Committee on Science, Space, and Technology today by best-selling author of The Martian, Andy Weir. The hearing, entitled “Next Steps to Mars: Deep Space Habitats,” is exploring what NASA’s plans are for the development of deep space habitation.

Worth Reading: The API fight everyone loses

Attorneys for the Oracle and Google companies presented opening statements this week in a high-stakes copyright case about the use of application-programming interfaces, or APIs. As Oracle eagerly noted, there are potentially billions of dollars on the line; accordingly, each side has brought “world-class attorneys,” as Judge William Alsup noted to the jury. And while each company would prefer to spend their money elsewhere, these are businesses that can afford to spend years and untold resources in the courtroom. -via deeplinks

Identifying bad ECMP paths

In the talk Move Fast, Unbreak Things! at the recent DevOps Networking Forum,  Petr Lapukhov described how Facebook has tackled the problem of detecting packet loss in Equal Cost Multi-Path (ECMP) networks. At Facebook's scale,  there are many parallel paths and actively probing all the paths generates a lot of data. The active tests generate over 1Terabits/second of measurement data per Facebook data center and a Hadoop cluster with hundreds of compute nodes is required per data center to process the data.

Processing active test data can detect that packets are being lost within approximately 20 seconds, but doesn't provide the precise location where packets are dropped. A custom multi-path traceroute tool (fbtracert) is used to follow up and narrow down the location of the packet loss.

While described as measuring packet loss, the test system is really measuring path loss. For example, if there are 64 ECMP paths in a pod, then the loss of one path would result in a packet loss of approximately 1 in 64 packets in traffic flows that cross the ECMP group.

Black hole detection describes an alternative approach. Industry standard sFlow instrumentation embedded within most vendor's switch hardware provides visibility into the Continue reading
