Why hiring the ‘best’ people produces the least creative results — Quartz

The complexity of modern problems often precludes any one person from fully understanding them. Factors contributing to rising obesity levels, for example, include transportation systems and infrastructure, media, convenience foods, changing social norms, human biology and psychological factors. Designing an aircraft carrier, to take another example, requires knowledge of nuclear engineering, naval architecture, metallurgy, hydrodynamics, […]

Context-Aware Micro-segmentation – Remote Desktop Session Host Enhancements for VMware Horizon

In a previous post my colleague, Stijn, discussed the enhancements to how NSX for vSphere 6.4 handles Remote Desktop Session Host, RDSH, systems with the Identity-based Firewall and Context-Aware Micro-segmentation.

Remote Desktop Services is an underlying technology from Microsoft that many vendors take advantage of to provide overlay management and application deployment technologies for. In this post, we’re going to discuss how NSX for vSphere 6.4 allows customers to run RDS hosts with granular security for VMware Horizon systems.

VMware Horizon can provide multiple users the ability to connect to a single system to access their applications using the RDSH technology. These users can be of the same type, for example all HR users, or of multiple types, HR and Engineering users. In previous versions of NSX, it was not possible to individually secure user sessions and create Distributed Firewall (DFW) rule sets according to the user session logged into an RDSH server. This meant less flexibility in controlling what users could access data center application servers without isolating one set of users to one RDSH server. This model created a very rigid architecture for Horizon customers to follow.

Horizon allows customers Continue reading

Worth Reading: Bringing DNS security to the user

All of these efforts are aimed at protecting the complete path between the user and the service. This means authentication and encryption should start at the edge of the network, with the end user. As just about any interaction on the Internet starts out with a query for a domain name, it puts the DNS at the core of achieving this ultimate goal. —Benno Overeinder @APNIC

IDG Contributor Network: The top 4 industrial enterprise requirements of IoT application enablement platforms (AEP)

With over 400 self-proclaimed IoT platforms in the market, it doesn’t surprise me that industrial enterprises are hindered trying to identify, test and select a high quality IoT platform. Platform vendors’ marketing materials contain the same messages, their RFX responses always affirm “full compliance” with all requested capabilities and they have partnerships with the same cloud vendors. With over 400 self-proclaimed IoT platforms in the market, the only way to truly know each platform is to use it.What makes a great IoT AEP? An Application Enablement Platform (AEP) is a technology-centric offering optimized to deliver a best-of-breed, industry-agnostic, extensible middleware core for building a set of interconnected or independent IoT solutions for customers. An AEP links IoT devices and applications, delivering data to allow industrial enterprises to implement predictive maintenance, machine learning, factory automation, asset logistics, surveillance and many other applications. With IoT platform revenue slated to grow to USD 63.4 billion by 2026, IoT application enablement is one of the most highly demanded enterprise IoT platforms.To read this article in full, please click here

The internet will miss John Perry Barlow

John Perry Barlow, who died in San Francisco last week at age 70, was an important pioneer for internet freedom. But he was much, much more than that. He was the kind of Renaissance Man that today’s internet moguls can’t even dream of emulating. And that is a huge loss for the world of technology — and the world at large.Barlow’s wide-ranging influence You may not have heard of Barlow, but you’ve probably been influenced by him in a wide variety of surprising ways. For one thing, he was a co-founder — and at his passing, vice chairman — of the Electronic Frontier Foundation, which is considered “the leading nonprofit organization defending civil liberties in the digital world.” Back in 1990, when the EFF was formed, Barlow helped popularize the term “cyberspace.” He was a director of the WELL (Whole Earth ’Lectronic Link), the seminal online community, and he was an influential early voice at Wired magazine.To read this article in full, please click here

IDG Contributor Network: Cloud strategy: hybrid and multi cloud are not the same

IDC tells us that most companies are using more than one cloud and that cloud usage isn’t just about cost savings. Three out of every four companies are using cloud to chase additional revenue in the form of new customers, risk mitigation, IoT enablement or time to market gains. Most are using multiple external cloud services.However, especially as microservices become the dominant approach to new application development because of the iteration speed improvements that it provides, it has become important to distinguish the different ways that more than one cloud can be utilized. Specifically, the differences lie in where you sit in an organization and what you are trying to optimize from that seat. Although historically we’ve used the terms interchangeably, hybrid and multi cloud are not the same.To read this article in full, please click here

IDG Contributor Network: Why the edge has moved to the forefront

Remember just a few years ago, when everyone was talking about cloud computing? While cloud was consuming all the air in the room, few people were paying attention to another technology trend—one with the potential to transform industrial enterprises. I’m talking about edge computing.The idea of placing computing resources at the network’s edge—at or near where production processes are occurring—is not a completely new idea. Industrial control has relied on distributed computers to control manufacturing machines and processes for decades. But as manufacturers come under increasing competitive pressure, the need to optimize their efficiency, productivity and quality has become a matter of survival. This imperative requirement is driving companies across the industrial spectrum to look at how pushing intelligence out to the edge can help them gain a competitive advantage.To read this article in full, please click here

Automation Win: MPLS/VPN Service Deployment

I always encourage the students attending the Building Network Automation Solutions online course to create solutions for problems they’re facing in their networks instead of wasting time with vanilla hands-on assignments.

Francois Herbet took the advice literally and decided to create a solution that would configure PE-routers and create full-blown device configurations for CE-routers.

The Blind Men and the Elephant

640px-elephas_maximus_eye_closeup Bufferbloat is responsible for much of the poor performance seen in the Internet today and causes latency (called “lag” by gamers), triggered even by your own routine web browsing and video playing.

But bufferbloat’s causes and solutions remind me of the old parable:

It was six men of Indostan, to learning much inclined,
who went to see the elephant (Though all of them were blind),
that each by observation, might satisfy his mind.

……. (six stanzas elided)

And so these men of Indostan, disputed loud and long,
each in his own opinion, exceeding stiff and strong,
Though each was partly in the right, and all were in the wrong!

So, oft in theologic wars, the disputants, I ween,
tread on in utter ignorance, of what each other mean,
and prate about the elephant, not one of them has seen!

John Godfrey Saxe

Most technologists are not truly wise: we are usually like the blind men of Indostan. The TCP experts, network operators, telecom operators, router makers, Internet service operators, router vendors and users have all had a grip *only* on their piece of the elephant.

The TCP experts look at TCP and think “if only TCP were Continue reading

NASA Social OA-4 Tours and Launch

In December 2015 I had the distinct honor to be selected to attend a NASA Social event that coincided with the OA-4 launch, an ISS resupply mission. NASA runs these events occasionally to give the world some insight into what goes on at various locations pertaining to the space industry. There’s a lot of really cool work going on, and I’m happy to finally have a chance to publish my experience on this amazing trip.

Dipping my toes in the IoT pool: Microsoft DevKit IoT Board

In my personal life, I’ve jumped in the SmartHome head first, but I’ve been really reluctant to blur the lines into my professional life. Recently, I saw something that changed all that. The Microsoft IoT DevKit board.

NewImage

What is it?

This is Microsoft hardware product that allows developers to jump into the IoT pool. Specifically, the Microsoft Azure IoT hub pool. This is a very capable board with multiple sensors.

What sensors you ask?

Humidity:
Air Pressure
Temperature
Magnetometer
Motion
Microphone

Basically, it’s a really good sensor that can grab the majority of the physical measurements that we want to look at in the IoT world.

What do I do with it?

Right now, this is really just a tech toy for me. I have no specific projects that I’m trying to achieve. Rather this is a device that I’m using to try and really understand HOW the IoT ecosystem works and ensure my employability in years to come. So I don’t have any specific goals, but that’s really ok because Microsoft has been wonderful enough to supply us with the Microsoft IoT DevKit page over at Github which has a few different projects that allow me to grow Continue reading
