How Yahoo’s Internal Hadoop Cluster Does Double-Duty on Deep Learning

Five years ago, many bleeding edge IT shops had either implemented a Hadoop cluster for production use or at least had a cluster set aside to explore the mysteries of MapReduce and the HDFS storage system.

While it is not clear all these years later how many ultra-scale production Hadoop deployments there are in earnest (something we are analyzing for a later in-depth piece), those same shops are likely on top trying to exploit the next big thing in the datacenter—machine learning, or for the more intrepid, deep learning.

For those that were able to get large-scale Hadoop clusters into …

Microsoft’s monthlong delay of patches may pose risks

Microsoft has decided to bundle its February patches together with those scheduled for March, a move that at least some security experts disagree with."I was surprised to learn that Microsoft wants to postpone by a full month," said Carsten Eiram, the chief research officer at vulnerability intelligence firm Risk Based Security, via email. "Even without knowing all the details, I find such a decision very hard to justify. They are aware of vulnerabilities in their products and have developed fixes; those should always be made available to customers in a timely fashion."Microsoft took everyone by surprise on Tuesday when it announced that this month's patches had to be delayed because of a "last minute issue" that could have had an impact on customers. The company did not initially specify for how long the patches will be postponed, which likely threw a wrench in some systems administrators' patch deployment plans.To read this article in full or to leave a comment, please click here

Amazon’s Alexa gains support for Outlook calendars

Users of Amazon’s Alexa virtual assistant can now ask it questions about the contents of their Microsoft-hosted calendars. On Wednesday, the assistant gained the ability to interact with calendars from Outlook.com and Office 365, similar to how it works with Google Calendar.Amazon didn’t make an announcement for the new feature. When asked about the change, a spokesperson for the company said that it was designed to only work with personal calendars.That said, it was possible for me to connect my Office 365 calendar, which is provided through an enterprise subscription. When asked about what’s on my schedule, Alexa answered with the contents of my work calendar. It’s unclear if Amazon plans to continue supporting that functionality, and it may break at any time.To read this article in full or to leave a comment, please click here

Worth Reading: Intel’s ticking time bomb

It started somewhat innocently. Cisco released a field notice that there was an issue with some signal clocks on a range of their networking devices. This by itself was a huge issue. There had been rumblings about this issue for a few months. Some proactive replacement of affected devices to test things. Followed by panicked customer visits when the news broke on February 2nd. Cisco looked like they were about to get a black eye. —The Networking Nerd

IDG Contributor Network: Why big data projects fail and how to make 2017 different

Major shifts are happening in our ecosystem as companies strive to become fully data-driven in the digital era. Gathering insights from data has become increasingly complicated due to a tidal wave of enterprise applications generating data.In addition, billions of users and trillions of connected “things” generate exponentially more data outside the enterprise. At the center, enterprises deploy cloud, mobile, and analytics technologies to hopefully turn that data into insight. Unfortunately, Gartner predicts that 2017 will see  60 percent of big data projects fail. They won’t go beyond piloting and experimentation phases, and will eventually be abandoned. To read this article in full or to leave a comment, please click here

Tech groups gear up for FISA surveillance fight

A controversial provision in U.S. law that gives the National Security Agency broad authority to spy on people overseas expires at the end of the year, and six major tech trade groups are gearing up for a fight over an extension.Section 702 of the Foreign Intelligence Surveillance Act expires on Dec. 31, and Congress almost certain to extend it in some form. The tech trade groups, including BSA, the Consumer Technology Association, and the Computer and Communications Industry Association, are asking lawmakers to build in new privacy protections for internet users. "It is critical that Congress takes a balanced yet focused approach with respect to Section 702," the groups said in a letter sent to top lawmakers Wednesday. "We urge your committees to ensure that any reauthorization includes meaningful safeguards for internet users' privacy and civil liberties."To read this article in full or to leave a comment, please click here

How Philips is turning toothbrushes and MRI machines into IoT devices

The Philips FlexCare Platinum Connected toothbrush is more than just a device for keeping your mouth clean – it’s an IoT machine. Wireless sensors measure the location, pressure and scrubbing patterns of the 31,000 strokes-per-minute vibrating bristles. The data is transferred via Bluetooth to a mobile app that provides a three-dimensional post-brush analysis of coverage, recommending areas of the mouth that should be “touched up” or given extra attention. There’s an option to send a month-long history of brushing patterns to your dentist to keep them informed of your brushing habits. And all of this data, along with many of Philips’ other connected device efforts, run out of Amazon Web Services’ cloud. It’s a new era of Intenet of Things-enabled machines, and Philips wants to be on the cutting edge of offering its consumer and business customers access to more data, which they hope will help keep patients more healthy and the machines running more smoothly.To read this article in full or to leave a comment, please click here

IDG Contributor Network: Private jets and private clouds

What’s your reaction when you learn that a company keeps a fleet of private jets? Does it suggest that the company is generally frugal and prudent with shareholder money? Or does it raise concerns that perhaps the company is spending in ways that wouldn’t withstand closer scrutiny? Given the tremendous expenses involved, objective financial analysis usually recommends against it, instead using commercial air travel services, maybe with upgrades in certain exceptional circumstances.Similar concerns should arise when you learn that a company keeps private data centers. Objective financial analysis of owning and operating such complicated systems increasingly shows that other choices make more sense. That’s because of the growing availability of so many attractive commercial information technology services, ranging from software-as-a-service to public cloud infrastructure.To read this article in full or to leave a comment, please click here

Python – Kirk Byers Course Week 2 Part 3

This post will describe the exercises and solutions for week two of Kirk Byers Python for Network Engineers.

The next excercise is to work with output from “show ip bgp”:

III. You have the following four lines from 'show ip bgp':

entry1 = "*  1.0.192.0/18   157.130.10.233        0 701 38040 9737 i"
entry2 = "*  1.1.1.0/24     157.130.10.233        0 701 1299 15169 i"
entry3 = "*  1.1.42.0/24    157.130.10.233        0 701 9505 17408 2.1465 i"
entry4 = "*  1.0.192.0/19   157.130.10.233        0 701 6762 6762 6762 6762 38040 9737 i"

Note, in each case the AS_PATH starts with '701'.

Using split() and a list slice, how could you process each of these such that--for each entry, you return an ip_prefix and the AS_PATH (the ip_prefix should be a string; the AS_PATH should be a list):

Your output should look like this:

ip_prefix             as_path                                           
1.0.192.0/18          ['701', '38040', '9737']                          
1.1.1.0/24            ['701', '1299', '15169']                          
1.1.42.0/24           ['701', '9505', '17408', '2.1465']                
1.0.192.0/19          ['701', '6762', '6762', '6762', '6762', '38040', '9737']

Large-Scale Quantum Computing Prototype on Horizon

What supercomputers will look like in the future, post-Moore’s Law, is still a bit hazy. As exascale computing comes into focus over the next several years, system vendors, universities and government agencies are all trying to get a gauge on what will come after that. Moore’s Law, which has driven the development of computing systems for more than five decades, is coming to an end as the challenge of making smaller chips loaded with more and more features is becoming increasingly difficult to do.

While the rise of accelerators, like GPUs, FPGAs and customized ASICs, silicon photonics and faster interconnects …
