Yahoo courts developers at its first mobile conference

Mobile users have become a vital part of Yahoo’s recovery effort, and on Thursday it tried to woo developers with new tools to help them build better apps using its services.The company held its first-ever mobile developer conference in San Francisco on Thursday, where it unveiled tools that help developers collect data about their apps and make money from them using Yahoo advertising services.Many of the tools come courtesy of Flurry, a mobile analytics and advertising company Yahoo acquired last year. Flurry now has more than 200,000 developers using it’s tools, Yahoo CEO Marissa Mayer said Thursday. Yahoo hopes to get even more developers on board by giving them new ways to see how their apps are performing and by baking Yahoo advertising options directly into Flurry.To read this article in full or to leave a comment, please click here

Android malware fakes phone shutdown to steal data

Next time you turn off your Android phone, you might want take the battery out just to be certain.Security vendor AVG has spotted a malicious program that fakes the sequence a user sees when they shut off their phone, giving it freedom to move around on the device and steal data.When someone presses the power button on a device, a fake dialog box is shown. The malware then mimics the shutdown animation and appears to be off, AVG’s mobile malware research team said in a blog post.“Although the screen is black, it is still on,” they said. “While the phone is in this state, the malware can make outgoing calls, take pictures and perform many other tasks without notifying the user.”To read this article in full or to leave a comment, please click here

Lenovo admits to Superfish screw-up, will release clean-up tool

Lenovo has admitted it “messed up badly” by pre-loading software on some consumer laptops that exposed users to possible attack, and said it will soon release a tool to remove it.“I have a bunch of very embarrassed engineers on my staff right now,” Lenovo CTO Peter Hortensius said in an interview Thursday. “They missed this.”Users have been complaining since September about the third-party program, called Superfish, which injects product recommendations into search results. But it only emerged Wednesday that the program also opens a serious security hole.To read this article in full or to leave a comment, please click here

Google Cloud offers security scanning for customer apps

NFD9: Cumulus Networks

Cumulus Networks gave a great presentation at Network Field Day 9. They presented their vision of how they’re working to improve networking. But they were also clear about what they don’t do, and where they will instead enable others.

Linux on a switch? Seems natural to me

Many network engineers started out running cables, and doing low-level networking. They build up to designing & running more complex networks. I came at it from a different direction. I first ran Linux systems in 1999. My first professional job was working with HP-UX in 2000, and I later moved into running Check Point firewalls on Nokia IPSO. I was well-used to working with Unix-like systems, and it was completely natural to me to run tcpdump on a network device.

To become an effective network security engineer, I had to learn more about routing & switching. But because I had that *nix background, I was always frustrated by the limited capabilities offered by IOS. “| include” is a poor substitute for grep. Yes, you can do some stuff with TCL, but would you want to? Packet capture was a poor joke until recently.

So when I first heard about Cumulus, it made a Continue reading

Nokia, Korea Telecom plan to demo 4G for machines, cars

A slower but more frugal version of LTE that has been customized for the Internet of Things will be demoed at Mobile World Congress next month.LTE was developed to provide high-speed transmission for smartphones and tablets, and has been a success in that regard. But with the growing popularity of connected wearables, smart meters and vehicles, the telecom industry has had to rethink LTE specifications to make it a better fit for related applications.At Mobile World Congress, Nokia and KT (Korea Telecom) will demonstrate a prototype of a customized version, which has been dubbed LTE-M. The alterations include changes to increase battery life and decrease the cost of devices that use it. The latter is in part achieved by decreasing bandwidth, which means less expensive components can be used.To read this article in full or to leave a comment, please click here

You broke the network. Do you confess?

Today we’re taking a deep look into mindset of the network professional – his or her soul -- when it comes to breaking something and owning up to the mistake … or not.Posted to Reddit’s section that is devoted to networking: “Have you ever accidentally broken something then fixed it immediately to find your colleagues praising your skills even though it (was) your lack of skills? How do you react?”The inquisitor answers his own question: “Generally speaking I've always let the peasants (end users) think I'm a wizard while I tell my boss what actually happened. What have you guys done in similar situations?”To read this article in full or to leave a comment, please click here

IDG Contributor Network: An LTE over Wi-Fi spectrum grab is coming

Unlicensed spectrum would be the logical place to expand traffic if, as mobile networks are finding, their licensed spectrum is running out.Why not shift over to unlicensed spectrum? It's unlicensed, after all, so anyone can use it. Who would object?Well, the answer to that question may be a bunch of Wi-Fi users, like you and me, if it doesn't work as promised and stomps on existing use, such as Wi-Fi.Wi-Fi at 5 GHzThe new piggy-backing technology uses the same Wi-Fi band that mobile device users are beginning to take advantage of in the home and workplace. That is 5 GHz—the free-to-use band you'll find in newer routers and mobile devices, like tablets and recent phones.To read this article in full or to leave a comment, please click here

Uber increases funding round by $1B to meet investor demand

The prospect of government oversight and steady stream of security issues facing Uber haven’t scared investors from the ride-hailing company, which will expand its latest round of venture funding by US$1 billion.In December, Uber initially raised $1.2 billion during a funding round. At that time, Uber estimated there was room for an additional $600 million in investments.Investor interest, though, proved greater. To meet the demand, Uber will expand that round and issue approximately 30 million additional shares valued at $33.31, according to documents filed Wednesday with the Delaware secretary of state. Uber is based in San Francisco and incorporated in Delaware.To read this article in full or to leave a comment, please click here

Show 224 – HTTP2. Its The Biggest (Network) Thing Happening on the Internet Today – Repost

HTTP/2 is now submitted to the RFC Editor and will bring major changes to networking. Efficient design means smaller firewalls, less bandwidth and faster response times for users. And the default to encryption means that transparent caches, proxies, IDS/IPS and other network security systems will be seriously impacted.

Network Dictionary – Whitebrand Ethernet

Whitebrand is a term used to describe a type of Ethernet switch that is a whitebox or generic manufacture but sold by a known IT brand. Juniper OCX1100, HP Open Network Switches are example. White-Box Switching + Vendor Branding = Whitebrand switching.  The other term used is “britebox” but this sounds like dishwashing liquid or something you […]

Vendors lay groundwork for 5G with greener and faster mobile networks

A new generation of mobile network equipment comes with lofty promises of better coverage and performance for subscribers, by making it easier for operators to add more capacity and support for new radio technologies.Mobile operators are facing a number of challenges, starting with building networks that won’t get overwhelmed by traffic growth mainly driven by video. The most straightforward way of doing this is adding more spectrum—or lanes, if you will—to their networks. It isn’t a coincidence that the recent AWS (Advanced Wireless Service) spectrum auction in the U.S. was a blockbuster and that operators want to use Wi-Fi frequencies for LTE.To read this article in full or to leave a comment, please click here

Sprint and T-Mobile defend unlocking policies

The Cisco CNPES Cert, First Exam (600-504) and Course

Do you think of yourself as a network engineer? Cisco’s Network Programmability Engineer Specialist (CPNES) certification represents Cisco’s first crack at a certification focused on network engineering in an SDN world. Today’s post begins to examine this certification by looking at the first of the two required exams: the 600-504 NPENG exam. We’ll look at both the exam and a related video course.

Other posts in this series:

• Introduction to Cisco’s SDN Certifications
• Cisco Network Programmability (SDN) Intro Course

Overview

First, to set the stage, Cisco currently offers four network programmability certifications. Loosely you can think of these as two networking-focused certs, and two development-focused certs, based on job roles. For the two networking-focused certs, one focuses on design, while one (the one discussed here) looks at engineering and implementation.

Figure 1: Overview of Cisco SDN Certifications

Today’s post focuses on the cisco network programmability engineering specialist (CNPES) cert, and specifically the first exam: the 600-504 NPENG exam. Basically, the NPENG exam covers SDN implementation but excludes ACI, while the second required exam, 600-512 NPENGACI, includes ACI.

This list provides the links for more details – for the certification, each of the two exams, and each of Cisco’s two Continue reading
