IDG Contributor Network: A better way to store solar power for data centers

As any data center operator will tell you, data centers use large amounts of power. In fact, one data center can use enough energy to power 180,000 homes.What with the costs and the eco-issues with fossil fuels, there's a race on to try to find better ways of powering these cathedrals to digital life.Many heavy data center users are looking to place their centers near sources of renewable power, for example. Facebook has opened one in Sweden that's near a hydro-electric plant.Solar is also pretty good, and wind-power turbines are another alternative power source attracting knee-jerk exuberance, despite their disadvantages, like uneven supply.To read this article in full or to leave a comment, please click here

Researchers show that IoT devices are not designed with security in mind

In the latest blow to Internet of Things (IoT) security, an analysis of smart home devices has found flaws that could give attackers access to sensitive data or allow them to control door locks and sensors.The research was performed by a team from application security firm Veracode for six up-to-date devices acquired in December and found serious issues in five of them. The tested devices were the Chamberlain MyQ Garage, the Chamberlain MyQ Internet Gateway, the SmartThings Hub, the Ubi from Unified Computer Intelligence Corporation, the Wink Hub and the Wink Relay.All of these devices enable remote control and monitoring over the Internet of various home automation devices and sensors, including door locks, interior switches and power outlets. Most of them connect to cloud-based services and users can interact with them through Web portals or smartphone applications.To read this article in full or to leave a comment, please click here

The Zen of Sailing Through IT Projects

For those of you who have worked in large companies, it’s common territory to be stuck riding waves on a ship without a sail. Said ship also has its anchor out, but the deck hands have forgot about that and the captain never logged it. The anchor is being dragged around due to the ship bobbing up and down on the waves, dragging a number of artifacts along at the same time and giving some image of movement. Sometimes the ship and crew head in the right direction but no one really knows what that is due to the ever whirring compass from a dodgy purchase and blocked views of the stars due to persistent clouds.

Fear not, this isn’t a terribly written nautical blog or a write up of a lost ship; it’s a description of a large-scale enterprise IT project.

This one particularly made me laugh. A lot of projects feel like this!

Waterfalls

In software development, there are numerous approaches to projects. A well known one is the waterfall method. It starts at the top follows a sequential path through the various phases. This methodology is unconsciously followed in enterprise projects through initiation, discovery, design, deployment and Continue reading

Review: Logitech MX Master wireless mouse

The scoop: MX Master wireless mouse, by Logitech, about $100What is it? Logitech calls the MX Master “The Precision Instrument for Masters of Their Craft,” implying that this is for workers or users who need specific, precise mousing movements, as well as a large number of buttons for customized computer actions. The wireless mouse also includes two options for connectivity - you can connect up to three computers via Bluetooth or you can use the traditional USB dongle, which Logitech calls the “Logitech Unifying Receiver.”MORE: 10 mobile startups to watch Why it’s cool: In addition to the standard left, right and middle buttons (the middle button is activated by pushing down on the middle scroll wheel), the MX Master includes a thumb scroll wheel on the side (for scrolling horizontally), two other buttons on the thumb area (for back-and-forward web browsing actions) and a new “gesture button” located in the area where your thumb would rest. Actions for these buttons are enabled through Logitech’s “Options” software, which you can download from the company’s web site. The software offers a range of customization options, everything from changing the direction of the scroll, speed of the mouse, sensitivity and Continue reading

EIGRP “FD is Infinity”

Let’s take a look at EIGRP and the state a route can get into where EIGRP tells you “FD is Infinity”.

First of all, every EIGRP speaker maintains a local database called the EIGRP topology table which holds a copy of every route received from every neighbor and every route being advertised by the local system. EIGRP performs its best-path decision process on the entries in this table in order to determine which routes are the best and then hands those best routes to the Routing Information Base (the RIB). By inspecting the entries in this table, you can see things like:

1. Bandwidth, Load, Delay, Reliability – the values to go into computing the composite metric
2. The actual composite metric that the local system has calculated
3. The composite metric that the neighbor calculated
4. Whether the route is internal or external
5. A list of all neighbors that advertised the route (neighbor’s router ID)
6. The feasible distance (FD) for the route
7. The metric for the route as seen in the RIB

I’ve used superscript numbers (^x) in the output below to indicate where each item in the list above is found.

Learning from Germanwings

On the 24th of March, the pilot of Germanwings flight 4U9525 into a field, killing everyone on board, including himself. This is a human tragedy — beyond what many of us will experience in our lifetimes. But it’s also an important object lesson to those of us who live in the world of engineering. Think through the entire realm of airline safety that has been put into place since the terrorist attacks on the 11th of September in 2001.

• Advanced scanning machines (which are not without their own share of controversy)
• Increased security inside the airplane, including locked cockpit doors
• Stricter regulations on liquids carried onto the airplane
• Removal of electronic items from bags so they can be independently assessed

The list feels almost endless to the person on the receiving end of all these new measures. The pilot, in this case, either bypassed the protection, or used it to his advantage. Advanced scanning machines, liquids restrictions, and laptop inspections can’t prevent someone intent on harming lots of people if they have control of the airplane itself. The locked cockpit door just created a “safe space” in which the co-pilot could work his plan out.

So what’s the point of Continue reading

Getting Ansible to talk to your Cisco devices

As a listener to the podcast you’ve probably heard about Ansible once or twice already. In short Ansible is a simple IT automation tool. It’s often mentioned together with Puppet, however a big difference is that Ansible is agentless. Using Puppet assumes that you have a Puppet agent installed on the nodes that you want […]

Article: Is NFV Relevant for Enterprise Networks?

Network Computing recently published my “Yes, NFV Is Important For The Enterprise” article. Short summary: NFV is (like BGP and MPLS) yet another technology that is considered applicable only to service provider networks but makes great sense in some enterprise contexts.

I’ll talk about enterprise aspects of NFV at Interop Las Vegas, and describe some NFV technical details and typical use cases in an upcoming webinar.

HTIRW: Reality at the Mic (2)

Last time we talked about a few things that go wrong in the IETF — this time we’ll talk about a few more things that can go wrong. Boiling the Ocean. Engineers, as a rule, like to solve problems. The problem is we often seem to think the bigger the problem, the better the solution. […]

All About That YANG at the 92nd IETF Meeting

I was at the 92nd IETF meeting in Dallas a few weeks ago. I attended 16 sessions, mostly in the routing area, and every single one had a discussion about the YANG data model (indeed most had several such discussions). 

YANG is the data modeling language for the NETCONF protocol. NETCONF/YANG was picked by the Interface to Routing System (I2RS) Working Group for an SDN controller to interact with IP/MPLS routers. It makes an IP/MPLS network programmable. There are other IETF protocols in play as well, such as Path Computation Element Protocol (PCEP). To make SDN management and orchestration (MANO) service aware, we need to bind these paths to the services they are intended for. This is where NETCONF/YANG data models come to the rescue. I was very pleased to see the attention NETCONF/YANG data models got at the IETF.  

One thing that can hinder quick adoption and implementation for some data models is competing proposals. Indeed, some camps have formed around competing proposals. This is not unusual in the IETF. Different Internet-drafts (documents intended to be adopted by Continue reading

Complaint alleges YouTube Kids pushes advertising content

The six-week-old YouTube Kids service is a “hyper-commercialized” environment that intermixes advertising and other programming in a way that deceives its target audience, a coalition of privacy and children’s advocacy groups said in a complaint to the U.S. Federal Trade Commission.Joining in giving YouTube Kids the big thumbs-down are the Center for Digital Democracy, the Campaign for a Commercial-Free Childhood and the American Academy of Child and Adolescent Psychiatry. They say the video app, targeted toward preschool children, blurs the lines between advertising and other programming using methods that are prohibited by federal regulations on commercial television.To read this article in full or to leave a comment, please click here
