Worth Reading

For whatever reason, we seem to have moved into the “summer doldrums” a bit early this year. Emails seem to just not being answered for weeks — if ever — several friends have emailed me in the last week or two ago asking if it was just them, or if the IT industry was going crazy. All that said, though, there is still a lot going on in the world of IT.

Geoff Huston — if you don’t follow the rantings of Geoff, you really should — makes a point I wish I’d thought of first. The Internet of Things isn’t necessarily a security risk so much as it’s just a stupidity risk. He uses the example of millions of smaller home based devices being shipped with hard coded IP addresses that impact time and DNS servers to make the point that once things are deployed, they don’t tend to be touched. “If it ain’t broke, don’t fix it.” He calls it the Internet of Stupid Things.

Along those same lines, I saw an article this week about how Microsoft is threatening the end of the world (or some such) because they’re ending support for Windows 2003 server. The Continue reading

Nuage Announces Underlay/Overlay Event Management Platform

During the ONUG event I met with Dimitri Stiliadis, the Co-Founder & Chief Technology Officer of Nuage Networks, who was excited to tell us about the latest product release, the Virtualized Services Assurance Platform (VSAP).

Virtualized Services Assurance Platform

The history of Nuage products has been fairly straightforward; they began with a virtualized networking solution targeted at data centers. More recently, Nuage Networks announced an expansion of that product into the branch office space. What was missing though, was a good way to monitor and manage the complex environment that was built, from underlay to overlay, from the WAN all the way to from virtual switch. When failures occur, they can be difficult to track down or, worse, you are flooded with alerts and left to figure out which ones are actually important, and which ones are the true root cause. To that end, Nuage Networks’ VSAP aims to provide visibility of the network and event correlation so that you can see what might be affected by a given network event.

VSAP is composed of two main components:

Route Monitor

The Nuage Route Monitor uses route protocols to peer with the production network in the data center, backbone, and anywhere else Continue reading

Wi-Fi Design and Capacity Planning Webinars, May 19th and 21st

Please consider attending webinars I'll be hosting on Wi-Fi design and capacity planning next week with Aruba Networks. I'll be talking about the key aspects to WLAN performance and the approach that I take to integrating coverage and capacity into a holistic design, as well as tools you can use to monitor WLAN performance after deployment to maintain a high-performing network and plan for growth.

These won't be traditional marketing webinars. If you're like me, you get invited to (and avoid) many webinars because they are too sales oriented and lack relevant engineering content. This isn't that. The goal of these webinars is to provide practical, real-world concepts and methods to help you design better Wi-Fi networks. Everyone deserves better Wi-Fi, right?

U.S. Webinar - May 19th at 11am PDT / 2pm EDT

China pushes for big jump in Internet speeds

China’s government is pressing for faster Internet access speeds and lower prices, two moves that aim to boost the number of its citizens going online.On Friday, all three of China’s telecommunications operators announced plans to lower broadband and data plan costs for consumers. This came a month after China’s premier Li Keqiang said the country needed to do more to expand Internet access.China has the world’s largest Internet-connected citizenry at over 649 million users, but that’s still less than half of the country’s population.

Build Your Development or Lab Environment with Ravello Systems

When preparing for my Simplifying Application Workload Migration workshop (coming in webinar format in autumn) I tried to find a solution that would allow me to recreate existing enterprise virtual network infrastructure in a cloud environment. Soon I stumbled upon Ravello Systems, remembered hearing about them on a CloudCast.net podcast, and got in touch with them to figure out whether they could help me solve that challenge.

It turned you might use Ravello Systems’ solution to implement disaster recovery, but I got way more excited about the possibility to use their solution for labs or testing. To learn more about that, listen to Episode 32 of Software Gone Wild.

To push electric cars, Seoul rolls out portable chargers with RFID

Seoul is trying to put one of the world’s highest concentrations of electric vehicles (EVs) on its roads with a project that would let drivers charge their vehicles in residential parking lots and other everyday locations.The city is planning to give out electric charger cables fitted with RFID readers that would allow drivers to recharge their batteries through standard power outlets at 100,000 locations—a huge increase from current numbers.Central to the project is a charger cable called the EV-Line, developed by Gyeonggi-based Power Cube. The cable has an RFID reader than can scan an RFID tag attached to power outlets in parking lots for apartments, offices and elsewhere. It also has a 3G wireless module.To read this article in full or to leave a comment, please click here

Revolutionaries vs. Lawyers

I am not a lawyer; I am a revolutionary. I mention this in response to Volokh posts [1, 2] on whether the First Amendment protects filming police. It doesn't -- it's an obvious stretch, and relies upon concepts like a protected "journalist" class who enjoys rights denied to the common person. Instead, the Ninth Amendment, combined with the Declaration of Independence, is what makes filming police a right.

The Ninth Amendment simply says the people have more rights than those enumerated by the Bill of Rights. There are two ways of reading this. Some lawyers take the narrow view, that this doesn't confer any additional rights, but is just a hint on how to read the Constitution. Some take a more expansive view, that there are a vast number of human rights out there, waiting to be discovered. For example, some wanted to use the Ninth Amendment to insist "abortion" was a human right in Roe v. Wade. Generally, lawyers take the narrow view, because the expansive view becomes ultimately unworkable when everything is a potential "right".

I'm not a lawyer, but a revolutionary. For me, rights come not from the Constitution. Bill of Rights, or Supreme Continue reading
