Leveraging IXP Colocation as an Enterprise

Providing a comprehensive solution for global connectivity is still not a trivial task. As most global enterprises know, the scale both geographically and organizationally can kill almost any well engineered network design.  Size and complexity aside, just designing for the next “XaaS” solution and cloud sprawl can greatly challenge most network engineers One approach to […]

Making a docker container for a Flask application

Recently I presented to you a project called PLAZA which basically serves as a Web UI for python scripts. It was a pleasure to see that this project was welcomed well and some folks even asked how they can get PLAZA to play with. My fault, I wanted to release it so bad that I missed

Using OpenSwitch Appliance With GNS3

Note: This article was originally published here.

Update:This post has been updated to account for some recent changes in the appliance configuration (support for up to 7 front ports). In my previous post I described my developer setup to work with OpenSwitch. At the end of my post I showed how to download the build system, and configure and build an ‘appliance’ image.

What Is An OpenSwitch Appliance?

The appliance is a virtual machine image (in OVA format) that could be run on VirtualBox or VMware (on this articule I will focus on VirtualBox) and provides a software datapath (based in OVS right now, but P4 support it’s landing soon). All the rest of the OpenSwitch stack is the same that you will see in a real hardware, and obviously the software datapath has certain limitations and features not implemented.

Despite his limitations, the appliance is a really nice way to get your hands into OpenSwitch without having real hardware.

If you are using the development environment, you can find the appliance .ova file on the images directory after completing the build, but otherwise you can also download a periodic image from the project archives (keep in mind Continue reading

Here’s what the new Intel will look like

The PC market has been in trouble for ages, but last year took the biscuit. Shipments dropped below 300 million for the first time since 2008, and IDC declared it the worst year in history. That explains a lot about what happened at Intel this week.The chip maker has been reducing its dependency on PCs for some time, preferring to focus on its more successful data center business. But the announcement that it would lay off 12,000 people is a sign that Intel is finally turning a corner.To read this article in full or to leave a comment, please click here

Magic Leap adds virtual reality head-tracking and possibly hand-tracking

A second demonstration of mega-venture Magic Leap’s virtual reality technology indicates that head-tracking has been added and possibly hand-tracking.Head-tracking, which wasn’t shown in the only other demonstration that happened over a year ago, lets a person move around a hologram to see it from different sides. Hand-tracking, which is a mouse-like metaphor interface that lets people interact with virtual objects using hand movements, also seems to have been added. The report also hints at the principals behind how Magic Leap’s virtual reality works. Wired reported on Kevin Kelly’s visit to Magic Leap in Fort Lauderdale, Florida, to experience the second public demonstration of the company’s version of virtual reality that it calls mixed reality (MR). A comparison of the Wired story with one written by Rachel Metz over a year ago for the MIT Technology Review measures Magic Leap’s progress.To read this article in full or to leave a comment, please click here

Software-Defined Networks .. A Primer

SDN, Software-Defined Networking, the trending technology that some friends/colleagues of mine like to refer to it as “Still Does Nothing”. Let’s see if it does some thing. SDN has been a market hype for few years now.  Out of laziness, I ignored it in the beginning then I had to catch up a bit later …

IDG Contributor Network: Bugs for cash: Bounty hunters in the new wild west of security

The business of bug hunting is a potentially lucrative one for both seasoned security researchers and amateurs with an interest in hacking. It’s an area that’s gaining legitimacy thanks to official bug bounty programs and hacking contests, but there’s still a seedy underbelly that unscrupulous bounty hunters can take advantage of if they successfully identify a vulnerability.The average cost of a data breach is $3.8 million, according to research by the Ponemon Institute. It’s not hard to understand why so many companies are now stumping up bounties. It can also be very difficult, time consuming and expensive to root out bugs and flaws internally. Turning to the wider security community for help makes a lot of sense, and where there’s need there’s a market.  To read this article in full or to leave a comment, please click here

Worth Reading: Rolling the root

…no cryptographic secret can be regarded as “absolute”. It’s all relative and the use of a key has some element of associated risk that the key is not a strict secret. If that’s the case, and if we cannot really understand the exact levels of risk associated with the use of a key, then why should we place our trust in any form of public key cryptography?

First Wave of Pascal GPUs Coming to European Supercomputer

There are few international supercomputing hubs sporting the systems and software prowess of the Swiss National Supercomputing Center (CSCS), which started with large-scale vector machines in 1992 and moved through a series of other architectures and vendors; from NEC at the beginning, to IBM, and most recently, Cray. In fact, the center has had an ongoing preference for Cray supercomputers, with an unbroken stretch of machines beginning in 2007.

In addition to choosing Cray as the system vendor, CSCS has been an early adopter and long-term user of GPU acceleration. According to the center’s director, Thomas Schulthess, teams there firmed …

Intel’s tablet adventure looking more like its netbook disaster

Intel's rise and fall in tablets are starting to resemble the company's misadventures in netbooks less than a decade ago.The company is quickly distancing itself from basic tablets, a market it prized as little as two years ago, to go after detachable devices, hybrids, and high-end tablets that can double as PCs.Intel could also ax some Atom tablet chip lines that brought the company success two years ago. Intel this week laid off 12,000 people as part of a restructuring plan that could also include cuts in some product lines.To read this article in full or to leave a comment, please click here
