ONF Announces SDN Certification Specifications

The Open Networking Foundation (ONF) announced their intent to create an SDN certification program back in September ‘14. The message since that time has been that they’re working on it. In June, at the ONS15 conference, the ONF showed a few more details, and now the ONF web site lists plenty of details about their new certification program. Today’s post kicks off what will likely be a few posts working through what the ONF has posted about their new certification exams.

Big Picture Overview

The official name of the program - ONF Certified Professional Program - begins its history with two certifications:

The two certifications separates the conceptual (the first certification) from the hands-on skills requirements (the second certification).

The Exams

Each certification requires that you pass a single exam, with the exam names being obvious as to which certification they apply.

CSDNA-110

CSDNE-111

The exams have a few key differences from what you may be used to seeing with vendor-focused exams. The big differences is that the exams will be offered online, with an honor system to prove that it’s you taking the exam. Obviously that’s a Continue reading

Yahoo ramps up tech to compete with daily fantasy sports pioneers

Yahoo, a trailblazer in the world of online fantasy sports, recently released a daily fantasy service, and the company plans to use its experience to compete with pioneers such as DraftKings and FanDuel in the daily fantasy market. It was a natural move for the fantasy sports mainstay, which launched its first offering in the late 90s, but it required technology innovation. "From an industry standpoint, if there was any doubt about the legitimacy of daily fantasy sports, the Yahoo announcement made it very clear that there's a business opportunity in this area," says Ben Shields, a lecturer in managerial communication at the MIT Sloan School of Management and author of The Sports Strategist: Developing Leaders for a High-Performance Industry and The Elusive Fan: Reinventing Sports in a Crowded Marketplace.

Hacker: ‘Hundreds of thousands’ of vehicles are at risk of attack

A security expert who recently demonstrated he could hack into a Jeep and control its most vital functions said the same could be done with hundreds of thousands of other vehicles on the road today. Security experts Charlie Miller and Chris Valasek collaborated with Wired magazine to demonstrate how they could remotely hack into and control the entertainment system as well as more vital functions of a 2015 Jeep Cherokee. Both hackers are experienced IT security researchers. Miller is a former NAS hacker and security researcher for Twitter and Valasek is the director of security research at IOActive, a consultancy.To read this article in full or to leave a comment, please click here

Why the Open Container Project is good news for CIOs

Application container giant Docker and upstart rival CoreOS have ceased hostilities following the announcement of the Open Container Project (OCP). The project will work to develop industry standards for a container format and runtime software.As a starting point, the OCP standards will be based on Docker technology: Docker has donated about 5 percent of its codebase to the project to get it going.The OCP will run under the auspices of the Linux Foundation, and its sponsors include AWS, Google, IBM, HP, Microsoft, VMware, Red Hat and HP as well as Docker and CoreOS. So this can be seen as an industry-wide initiative to ensure that containers meet the following criteria:To read this article in full or to leave a comment, please click here

CIOs say AppleCare for Enterprise is lacking

Apple's budding partnership with IBM culminated in the release of AppleCare for Enterprise, the company's business-specific support service, but for the vast majority of organizations that use Apple products the initiative is nothing more than a glorified Genius Bar. CIOs and IT professionals welcome Apple's recent interest in the enterprise, but many are still unclear on the levels of support and services the consumer giant offers — and few are satisfied with Apple's commitment. AppleCare for Enterprise, which is roughly 8-months-old, includes 24/7 phone and email support for all Apple hardware and software, on-site service from IBM, next-day device replacement, a designated account manager and one-hour response times for urgent issues. These services are virtually unattainable for most business customers because many don't have relationships with both Apple and IBM, a requirement for the support services.To read this article in full or to leave a comment, please click here

golang up and running on CentOS7

I’ve decided recently to get serious about learning golang.  I’ve had a great time playing around with other peoples code (Docker and Kubernetes namely) and it’s time for me to learn the language so I can contribute more than bash scripts.  For better of for worse, I’ve decided to start coding on a CentOS box.  I have a couple of reasons for doing this…

-Its the Linux distro I’m most familiar with currently
-I need to get better at working in Linux.  More stick time on straight CLI can’t hurt.  I feel like jumping into a full blown IDE might be a bit premature for me and possibly allow me to miss some of the basics as well.
-I plan to run the code on Linux servers (I think…?)

Disclaimer: Im just getting started in golang.  If something I suggest below is wrong, please tell me!  Still learning here

Note: I really struggle with the language called ‘go’.  So Im trying to call it golang everywhere I can.  It can seem like a bit much at times…

So let’s get started.  The goal of this post is to end Continue reading

Cell service at US airports varies from first class to middle-seat coach

Need something to watch on a flight? You can download an episode of your favorite show in less than a minute and a half on Verizon Wireless at Atlanta’s airport—or spend 13 hours doing the same over T-Mobile USA at Los Angeles International.The comparison of 45-minute HD video downloads illustrates the wide variation in cellular service at U.S. airports, which RootMetrics laid out in a report for the first half of 2015 that’s being issued Thursday. Atlanta’s Hartsfield-Jackson is the best place to go mobile and Verizon covers airports best overall, but just like security lines and de-icing delays, it all depends.RootMetrics tested mobile data connections using all four major carriers at the 50 busiest airports in the country, checking not just for speed but for how long it took to get on and how well the connection stayed up. The tests took place in well-used places like ticketing, baggage claim and terminal gates. RootMetrics didn’t test voice service or Wi-Fi networks.To read this article in full or to leave a comment, please click here

GNS3 Version 1.3: What’s new for Open-Source Routers

In 2014, the GNS3 development team launched a successful Kickstarter crowdfunding campaign to support development of a major new release, version 1.0, which was released in October that same year. I was happy to support the Kickstarter campaign and now I am finally getting around to taking a look at the new version of GNS3.

GNS3-v1x-064

The last time I used the GNS3 network simulator, it was at version 0.8.7. After producing version GNS3 1.0, the GNS3 development team has been updating it frequently. GNS3 is now at version 1.3.7.

In this post, I will look at the new version 1.3.7 of GNS3 and evaluate how it works with emulated routers and hosts running open-source software.

What’s new in GNS3 1.x

Below, I describe the new GNS3 1.x features in two sections. The first section summarizes new GNS3 features that are relevant to all users of GNS3, including those who will use GNS3 to emulate networks consisting of routers and hosts running open-source software. The second section summarizes new features relevant only those who are running commercial router images in GNS3.

Nigerian scammers buy exploit kits to defraud Asian businesses

A small group of Nigerian scammers is using more sophisticated methods to defraud mostly Asian businesses, including buying exploit kits and malware from experienced coders, according to a new report from FireEye.The security company said the group performs deep reconnaissance of its potential victims, jumping inside financial transactions in order to try to divert payments to their own accounts.The schemes are much more complex than so-called 419 or advance fee fraud scams, where random victims are induced to send funds in order to get a non-existent but much larger payoff.To read this article in full or to leave a comment, please click here

Microsoft follows Google to crack down on revenge porn

Microsoft will make it easier for people to request the removal of links to intimate images or videos from the company's Bing search engine if such content was posted online without their consent. This move comes in response to an increasingly prevalent phenomenon dubbed "revenge porn," where jilted former partners or extortionists upload sexually explicit content depicting the victims in an embarrassing light. "Unfortunately, revenge porn is on the rise across the globe," said Jacqueline Beauchere, Microsoft's chief online safety officer, in a blog post. "It can damage nearly every aspect of a victim's life: relationships, career, social activities. In the most severe and tragic cases, it has even led to suicide."To read this article in full or to leave a comment, please click here

Startup launches big data-as-a-service

For many enterprises, big data is hard and slow. Procurement and deployment of data infrastructure can be both expensive and difficult to scale at the pace that data volumes can grow. A startup founded by former Netezza executives says that the answer to these data engineering woes is the cloud. The startup, Cazena, came out of stealth today after two years of development with an enterprise big data-as-a-service offering intended to simplify and automate securely moving and optimizing big data processing in the cloud. It's a managed service platform that founder and CEO Prat Moghe — who served as senior vice president of strategy, products and marketing at Netezza — says addresses the security and complexity challenges that have kept many enterprises from migrating their big data workloads to the cloud.To read this article in full or to leave a comment, please click here
