Reflections on OpenStack Summit 2015 – A Market Maturing

I just came back from the OpenStack Summit 2015 in Vancouver and have finally caught my breath, so I can share some insights from this important event. It was incredible to bear witness to the continued growth of the OpenStack community in general and this event in particular. I still remember the very early summits when this industry was in its infancy. Back then, it seemed that most of the attendees were engineers conducting design sessions. This past week was gratifying to see how many real customers and actual OpenStack users were at the show. I would even go so far as to say they constituted the majority of the attendees.

Cumulus Networks co-founder and CTO Nolan Leake talks with visitors at the Cumulus Networks booth.

OpenStack Users Love Cumulus Networks

Cumulus Networks was very much present throughout the show — in our booth, in our partners’ booths, in panel sessions and, apparently, in the minds of many of the attendees. Cumulus Linux was seen as a universal network OS underlay for a variety of architectures. In addition to the sessions featuring our co-founder and CTO Nolan Leake, it was exciting to hear Cumulus Networks mentioned in many of the sessions I Continue reading

Research community looks to SDN to help distribute data from the Large Hadron Collider

When the Large Hadron Collider (LHC) starts back up in June, the data collected and distributed worldwide for research will surpass the 200 petabytes exchanged among LHC sites the last time the collider was operational. Network challenges at this scale are different from what enterprises typically confront, but Harvey Newman, Professor of Physics at Caltech, who has been a leader in global scale networking and computing for the high energy physics community for the last 30 years, and Julian Bunn, Principal Computational Scientist at Caltech, hope to introduce a technology to this rarified environment that enterprises are also now contemplating:  Software Defined Networking (SDN).  Network World Editor in Chief John Dix recently sat down with Newman and Bunn to get a glimpse inside the demanding world of research networks and the promise of SDN.To read this article in full or to leave a comment, please click here

Hyundai now offers an Android car, even for current owners

Android Auto, a product that up until now was only talked about by industry insiders and journalists, just shipped this week.Well, it didn't really ship, because it is being released as a software update to the 2015 Hyundai Sonata that existing owners can download. It will also be factory-installed on new models. Android Auto is an attempt to incorporate the convenience and safety of pairing a smartphone to a car without the distraction. It also points out that the car has become a software-driven mobile device, not unlike computers and smartphones.See also: Volvo charges extra for self-driving car feature that brakes for pedestrians Android Auto reduces driver distraction from smartphone use by integrating the smartphone with the console stereo system that the industry calls a head-unit. It focuses the driver's attention in short, safe interactions with the console display when using Android apps. According to Hyundai, "at any given daylight moment across America, approximately 660,000 drivers are using cell phones or manipulating electronic devices while driving, a number that has held steady since 2010." Distracted driving endangers drivers and their passengers, as well as those who share the road with them. According to the National Safety Board, Continue reading

Synology patches serious flaws in its network-attached storage devices

Network-attached storage (NAS) manufacturer Synology fixed several vulnerabilities in its devices’ software, one of which could allow attackers to compromise the data stored on them.The most serious vulnerability is located in the Synology Photo Station, a feature of DiskStation Manager (DSM), the Linux-based operating system that runs on the company’s NAS devices.Synology Photo Station allows users to create online photo albums and blogs that can be accessed remotely using the NAS device’s public IP (Internet Protocol) address.Researchers from Dutch firm Securify found that Photo Station did not properly sanitize user input, allowing potential attackers to inject system commands that would be executed with the privileges of the Web server.To read this article in full or to leave a comment, please click here

Heads up: Google Glass may be coming back

According to reports last week in the Financial Times, Google really is working on a new version of Glass, the now-cancelled wearable device that became the poster child for clueless tech products creeping out normal people.Google has claimed that it would continue working on the device since it stopped selling it in January, but until now there's been no word on what the company had in mind. Was it hoping to make a few tweaks and come up with a new marketing campaign and hope that would be enough for a successful re-launch? Or was the plan to completely scrap Google Glass as is and develop a new product based on what it learned from the first attempt?To read this article in full or to leave a comment, please click here

Just. Write.

Somewhere, someone is thinking about writing. They are confused where to start. Maybe they think they can’t write well at all? Perhaps they even think they’ll run out of things to say? Guess what?

Just. Write.

Why A Blog?

Social media has taken over as the primary form of communication for a great majority of the population. Status updates, wall posts, and picture montages are the way we tell everyone what we’re up to. But this kind of communication is fast and ephemeral. Can you recall tweets you made seven months ago? Unless you can remember a keyword, Twitter and Google do a horrible job of searching for anything past a few days old.

Blogs represent something different. They are the long form record of what we know. They expand beyond a status or point-in-time posting. Blogs can exist for months or years past their original post date. They can be indexed and shared and amplifed. Blogs are how we leave our mark on the world.

I’ve been fielding questions recently from a lot of people about how to get started in blogging. I’m a firm believer that everyone has at least one good blog post in them. One story Continue reading

Waste Not a Moment (Time Management)

One of the legends surrounding people who get a lot done is they simply don’t sleep. It’s long been said that I have some number of clones who do part of my work, or perhaps that if you ask different clones the same question, you’ll get different answers. This has, of course, been verified scientifically… But the truth is busy people do sleep, and they don’t have clones.

What they don’t do is waste the one resource everyone has a limited supply of — time. In the British Navy of yore, there was a phrase for this focus on using time effectively:

Waste not a moment.

Now I’m not here to give you time management tips and tricks. I’m happy enough to tell you what I do that seems to work. For instance —

• Set aside specific times to check email; don’t check it constantly.
• Schedule time to read and learn every day; still, however, slip in reading while you’re waiting in line, waiting on dinner by yourself, etc.
• Don’t spend a lot of time on social media. Don’t read the comments to a story, just the story.
• Don’t feel guilty about deleting things, or not reading them.
• Corollary one: Continue reading

Infinit improves its iPad user interface, partners with HTC to speed up file sharing

French start-up Infinit has customized its iOS client for Apple’s iPads and partnered with HTC to put its free software for speeding up file sharing on the company’s smartphones.Infinit has developed a peer-to-peer technology that the company says lets users share files faster than when using services such as Dropbox, Google Drive or Apple’s AirDrop,. The Tuesday’s announcements build on the launch of its applications for Android and iOS at the end of March.The iOS app has been upgraded to work better on Apple’s tablets. A lot of people share files between their MacBooks and iPads, so customizing the layout of the user interface for the bigger tablet screens made sense, according to chief operating officer and co-founder Baptiste Fradin.To read this article in full or to leave a comment, please click here

Sony’s Xperia Z4 renamned Z3+ outside Japan, goes on sale in June

Sony’s new flagship smartphone, the Xperia Z4, will be called the Xperia Z3+ when it goes on sale outside Japan in June. The phone has a sleeker design, faster processor and better front camera than the Z3 it replaces.Like the Z4, the Xperia Z3+ was announced with little fanfare compared to events organized by competitors Samsung Electronics and LG Electronics. The low-key launch on Tuesday doesn’t necessarily reflect badly on the product, but raises the question of how committed Sony is to its struggling smartphone unit.The Z3+ and Z4 are both available with 32GB of integrated storage. The only difference between them is that the Z4 is also available in a 64GB version. Both models have the option to add another 128GB using their microSD card slots.To read this article in full or to leave a comment, please click here

7 free Wi-Fi stumbling and surveying tools for Windows and Mac

Following up on our previous article highlighting 8 free Wi-Fi stumbling and surveying tools, here are 7 more tools that provide important details on known and unknown aspects of your WiFi network. Though enterprise-level solutions like AirMagnet Wi-Fi Analyzer and Ekahau Spectrum Analyzer have much more functionality, the free tools discussed here can be useful in a number of scenarios. For smaller networks, you might be able to get away with just using simple freeware tools for all of your Wi-Fi surveying needs. For larger wireless LANs (WLAN), these tools come in handy for a quick peek at the airwaves during design, deployment, or troubleshooting.

Link Aggregation in OpenFlow Environment

One of my readers couldn’t figure out how to combine Link Aggregation Groups (LAG, aka Port Channel) with OpenFlow:

I believe that in LAG, every traditional switch would know how to forward the packet from its FIB. Now with OpenFlow, does the controller communicate with every single switch and populate their tables with one group ID for each switch? Or how does the controller figure out the information for multiple switches in the LAG?

As always, the answer is “it depends”, and this time we’re dealing with a pretty complex issue.

This is how we get ants
