The PC upgrade cycle slows to every five to six years, Intel’s CEO says

The upgrade cycle for PCs has slowed down drastically, now extending to nearly six years, Intel CEO Brian Krzanich said on Wednesday."[The] replacement cycle for the PC has extended," Krzanich said. "Four years was the average, now it has moved to about five to six years."Intel needs to ramp up its efforts and release the right innovations so people are motivated to upgrade PCs quickly and easily, Krzanich said at the Bernstein Strategic Decisions Conference in New York."Right now, it's easier to move your phone to a new phone than your PC to a new PC," he said. "We've got to go fix some of those things."PC upgrades have slowed because current operating systems can run well on older Intel-based PCs. Five years ago, Intel shipped Core processors code-named Sandy Bridge, and they can capably run Microsoft's Windows 10.To read this article in full or to leave a comment, please click here

Understanding Deep Text, Facebook’s text understanding engine

“One morning I shot an elephant in my pajamas. How he got in my pajamas, I don't know.”That Groucho Marx quote illustrates why it’s difficult for computers to understand humans. When programming for computers to understand humans, one must account for vagueness, ambiguity and uncertainty to distil the meaning of human language.Facebook announced today that it can now do that with Deep Text, a deep learning-based text-understanding engine running a neural network that can understand with near-human accuracy the textual content of several thousands of posts per second—and in more than 20 languages.Consumers interacting with computers Consumers regularly interact with computers trained with machine-learning techniques that understand human language. Ask Siri for the best Japanese restaurant in San Francisco, and Siri will give you a list of restaurants. Or ask Google how many people live in Lisle, Illinois, and Google will reply with the answer from the U.S. census. These intelligent systems parse the question like school children, using syntax to diagram a sentence and then answer the question with structured data sets: the list of restaurants labeled San Francisco and Japanese or the quantity of people labeled Lisle, IL, in the census database.To Continue reading

Microsoft rolls out SQL Server 2016 with a special deal to woo Oracle customers

The next version of Microsoft's SQL Server relational database management system is now available, and along with it comes a special offer designed specifically to woo Oracle customers. Until the end of this month, Oracle users can migrate their databases to SQL Server 2016 and receive the necessary licenses for free with a subscription to Microsoft's Software Assurance maintenance program. Microsoft announced the June 1 release date for SQL Server 2016 early last month. Among the more notable enhancements it brings are updateable, in-memory column stores and advanced analytics. As a result, applications can now deploy sophisticated analytics and machine learning models within the database at performance levels as much as 100 times faster than what they'd be outside it, Microsoft said.To read this article in full or to leave a comment, please click here

Microsoft ships a major update to its HoloLens platform

Just as the month was about to end, Microsoft announced the release of the May 2016 Update for HoloLens, the first major software update to the virtual reality (VR) headset it's developing since it offered the developer edition.Considering it's been just two months since the Developer Kit and first wave of devices went out at the Build 2016 conference, Microsoft sure has added quite a bit to this update. The company also announced it was shipping headsets to a second wave of developer applicants.The full list of additions and changes to the May 2016 Update for HoloLens is rather lengthy, so we've boiled it down for you:To read this article in full or to leave a comment, please click here

IBM buys EZSource to help transform your mainframe apps for the digital world

The digital transformation train may have already left the station, but for companies with legacy mainframe applications, it's not always clear how to get on board. On Wednesday, IBM announced an acquisition that could help.The PC giant will acquire Israel-based EZSource, it said, in the hopes of helping developers "quickly and easily understand and change mainframe code."EZSource offers a visual dashboard that's designed to ease the process of modernizing applications. Essentially, it exposes application programming interfaces (APIs) so that developers can focus their efforts accordingly.To read this article in full or to leave a comment, please click here

Raspberry Pi real-time network analytics

The Raspberry Pi model 3b is not much bigger than a credit card, costs $35, runs Linux, has a 1G RAM, and powerful 4 core 64 bit ARM processor. This article will demonstrate how to turn the Raspberry Pi into a Terribit/second real-time network analytics engine capable of monitoring hundreds of switches and thousands of switch ports.
The diagram shows how the sFlow-RT real-time analytics engine receives a continuous telemetry stream from industry standard sFlow instrumentation build into network, server and application infrastructure and delivers analytics through APIs and can easily be integrated with a wide variety of on-site and cloud, orchestration, DevOps and Software Defined Networking (SDN) tools.
A future article will examine how the Host sFlow agent can be used to efficiently stream measurements from large numbers of inexpensive Rasberry Pi devices ($5 for model Zero) to the sFlow-RT collector to monitor and control the "Internet of Things" (IoT).
The following instructions show how to install sFlow-RT on Raspbian Jesse (the Debian Linux based Raspberry Pi operating system).
wget http://www.inmon.com/products/sFlow-RT/sflow-rt_2.0-1092.deb
sudo dpkg -i --ignore-depends=openjdk-7-jre-headless sflow-rt_2.0-1092.deb
We are ignoring the dependency on openjdk and will use the default Raspbian Java 1.8 version Continue reading

Google will help people find lost iPhones

Google is giving iPhone users another way to find their misplaced devices -- by searching the Web for it. Soon, when iPhone or Android users enter "I lost my phone" at Google.com, the search engine will respond with options that will allow them to ring the device, or locate it on a map. Right now, users can already get access to that functionality through Google's My Account feature, which serves as the nexus for people to understand and access the information connected to their Google account.Unlike Apple's Find my iPhone, Google's phone location feature isn't capable of locking an iPhone or remotely erasing it. Still, it may be a useful feature for someone who have misplaced his phone and just wants to figure out where it is.To read this article in full or to leave a comment, please click here

Worth Reading: Automation, Robotics, and the Future

And humility because of the poorness of our ability to peer into the future. When reviewing the mountains of books and magazine articles that have sought to predict what the future holds in automation and related fields, when reading the hyped tech headlines or when looking at the many charts and tables extrapolating from the past to help us forecast the future, it is striking to see how often our predictions go wrong.

Hey, Microsoft! Fish or cut bait on enterprise phones

Microsoft has a shot at saving what remains of its smartphone strategy, but the pivot toward the enterprise must be quick, an analyst said today."They're essentially starting over from scratch," John Delaney, an IDC analyst who covers mobility in Europe, said in an interview. "By the end of the year, they must show commitment from major ISVs and some really good mobile apps."Last week, Microsoft announced it would take another $950 million charge against earnings for the failure of its smartphone group to meet expectations, and lay off another 1,850 employees, two thirds of them former workers at Nokia, which Microsoft acquired two years ago.To read this article in full or to leave a comment, please click here

Intel faces a challenge in the server market with new ARM chips

Intel has doubled down on servers as it looks to shed its reliance on PCs, but the chip maker's ARM competitors are ready to challenge it.New server and appliance chips based on the ARM architecture were announced at Computex in Taipei this week. ARM-based chips dominate smartphone and tablets, but the new chips from Cavium and Marvell show the processors are maturing quickly for use in servers.ARM servers are seen as a power-efficient alternative to Intel's x86-based systems, with companies looking to cut electric bills in data centers. ARM server chips have been around for years but have failed to register an impact because of hardware and software problems.To read this article in full or to leave a comment, please click here

AP misses date of Lincoln’s death by four score and 20 years; we all miss copy editors

The typo itself – an Associated Press story reported that Abraham Lincoln was assassinated in 1965 instead of 1865 – was just that, a typo, as even a middle-schooler knows our 16th president never lived to hear the Beatles.However, among journalists of a certain age (mine), the distressing though not unexpected aspect of the miscue was that the erroneous date made it onto so many prestigious news sites. As a 1970s-era college friend of mine put it in an email subject line: “Copy editing was a fine profession ...”Meaning that back before the near-extinction of copy editors, it would have been unlikely that the Associated Press would have allowed such a gaffe, never mind that it would have gone unnoticed by so many AP-subscriber news organizations.To read this article in full or to leave a comment, please click here

DHCP Topology Customization Options

The Dynamic Host Configuration Protocol (DHCP) is widely used, and yet poorly understood. There are, in fact, a large number of options in DHCP—but before we get to these, let’s do a quick review of basic off-segment operation.

dhcp-relay

When the client, which has no IP address, sends out a request for configuration information, what happens? The Router, A, if it is configured to be a DHCP helper, will receive the packet and forward it to the DHCP server, which is presumably located someplace else in the network. The router generally knows what address to send the request to because of manual configuration—but how does the server know how to get the packet back to the original requester?

The helper—Router A in this case—inserts the IP address of the interface on which the request was received into the giaddr field of the DHCP packet. As boring as this might seem, this is where things actually get pretty interesting. It’s possible, of course, for a router to have an logical layer three interface that sits on a bridge group (or perhaps an IRB interface). The router obviously needs to be able to put more information in the DHCP request to handle this Continue reading

IDG Contributor Network: Triggered NetFlow — A Trick of the Trade

Triggered NetFlow: A Woland-Santuka Pro-Tip Vivek Santuka, CCIE #17621, is a consulting systems engineer at Cisco Systems who focuses on ISE for Cisco’s largest customers around the world. He and I devised, tested and deployed the methodology discussed in this blog entry, which we like to call “Triggered NetFlow.”NetFlow is an incredibly useful and under-valued security tool. Essentially, it is similar to a phone bill. A phone bill does not include recordings of all the conversations you have had in their entirety; it is a summary record of all calls sent and received.Cisco routers and switches support NetFlow, sending a “record” of each packet that has been routed, including the ports and other very usable information.To read this article in full or to leave a comment, please click here
