PlexxiPulse—The Impact of the Third Era

Trends in big data and IoT are driving a massive shift towards what we call the Third Era of information technology. Efficient and agile networks are needed to support the scaled-out applications of tomorrow. Ed Henry, an engineer here at Plexxi (also known as @NetworkN3rd) discussed the impact that the Third Era has on the network in a blog post this week. He explores how unprecedented amounts of data will affect network infrastructure, applications, and operations.

Network World: IDC’s state of the network at Interop: Change, or be left behind
By Brandon Butler
The confluence of mobile, social and big data trends are driving a tectonic transformation and businesses that do not change with these trends will be left behind, analysts from research firm IDC said at Interop. IDC says the so-called third platform, which includes those mega-trends of cloud and mobile workloads, will disrupt one-third of leading businesses across all sectors. “The third platform is already fueling a digital transformation across enterprise IT, and the only way IT will succeed is by transforming itself,” said Rohit Mehra, research vice president Continue reading

Not all certificate formats are created equal.

One of my favorite questions: ‘What format do you want that certificate in? Which then forces me to think and try and remember what was so special and different about all the certificate formats again? We’ll start with: PEM – Privacy Enhanced Mail Certificate represented in text format. In a Hex/ASCII format BASE64 encoded DER […]

ALF: Application Layer Fixup

I was talking about “application-layer gateways” on firewalls and NAT boxes with a fellow engineer, and we came to an interesting conclusion: in most cases they are not gateways; they don’t add any significant functionality apart for payload fixups for those broken applications that think carrying network endpoint information in application packets is a good idea (I’m looking at you, SIP and FTP). These things should thus be called Application Layer Fixups or ALFs ;)

Microsoft buying company that made stylus for Surface Pro 3

Microsoft will soon own the company that provided the stylus and touch display interface technology for its Surface Pro 3, according to a media report.The company has agreed to acquire Israel-based N-Trig for $30 million, according to The Wall Street Journal.Microsoft already had a minority stake of 6 percent in N-trig, but apparently had been in negotiations to acquire the company for months. In February, Israel's Haaretz newspaper said N-Trig was valued at less than $10 million, while Calcalist -- which originally broke the story of Microsoft looking to acquire the company -- reported that Microsoft would pay at least $200 million.To read this article in full or to leave a comment, please click here

Apple Watch, Samsung Edge glitches anger users, but no outright revolt

Problems with the new Apple Watch and Samsung Galaxy S6 Edge smartphone have infuriated some early adopters, but they still stay loyal to their favorite brand.Some have taken to user forums and tweets with expletive-deleted missives. This post Wednesday on an Android Central forum by Edge smartphone user Ajay Rivera seemed to summarize recent sentiment: "This was my second device to crap out and [a support rep] still treated me like an *****"Despite such anger, many in the industry dismiss glitches -- and subsequent user furor -- as par for the course with most new products.To read this article in full or to leave a comment, please click here

What can your Apple Watch do without your iPhone?

Strapped to your wrist, the Apple Watch goes everywhere that you go. Between it and the iPhone, it’s almost possible to leave your wallet at home. But what happens to the Watch when you leave your iPhone at home?Smart as the Apple Watch is, it’s still dependent on your smartphone for a number of its most common features, most notably anything that requires access to the Internet or pulls data from apps on your phone. But even should your iPhone be elsewhere—or off—your Apple Watch is still a pretty competent device. Time is of the essence Obviously the watch can tell time whether your iPhone is around or not. If it couldn't, that would be downright nutty.To read this article in full or to leave a comment, please click here

Can Microsoft’s new Surface 3 replace your notebook?

Microsoft wants you to abandon your preconceived notions of a laptop and embrace the Surface as more than just a tablet. In fact, Microsoft wants you to ditch your cumbersome notebook and one-dimensional tablet -- presumably your iPad -- and replace them with one device: the Surface 3. But even with an adjustable kickstand and full Windows 8.1, can the Surface 3 compete with a traditional notebook, or tablet for that matter?In 2012, the answer would have been -- and often was -- a resounding "No." However, the Surface line has come a long way in delivering the performance and usability you would need in order to dump your notebook. And Microsoft is not alone in its hybrid efforts. The trend is for notebook and tablet manufacturers to throw everything against the wall to see what sticks. As a result, the hybrid market is booming, and we've seen a slew of tablets that do a great impression of a notebook, and vice versa.To read this article in full or to leave a comment, please click here

Redesigning CloudFlare

Redesigning CloudFlare

Redesigning CloudFlare

CloudFlare’s original interface grew at an amazing speed. Visually, it hadn't changed much since CloudFlare’s launch in 2010. After several years of new features, settings, and ancillary UIs buried beneath clicks, it became clear that the user experience was lacking and would only get worse as we continued to add features. The question became: How could we make a UI that was versatile, scalable, and consistent?

If you haven’t yet, make sure you read Matthew’s post about the philosophy behind our new interface. This post will go into the details and the thought process behind designing our new dashboard.

Why a redesign?

We needed versatility for a growing variety of users and devices

As CloudFlare has grown, we now have a large variety of customers spanning four very different plan levels. We needed an interface that would work well for both the casual owner of a single blog, an agency managing many client sites, and enterprise customers that demand ultimate control. Also, the rise of responsive design was something we wanted to take seriously — the dashboard should be versatile enough to work just as well on every device.

We needed a platform that we could build upon

Mozilla may offer new browser features only on secure websites

Mozilla is planning to gradually favor HTTPS (HTTP Secure) connections over non-secure HTTP connections by making some new features on its browser available only to secured sites.The browser developer decided after a discussion on its community mailing list that it will set a date after which all new features will be available only to secure websites, wrote Firefox security lead Richard Barnes in a blog post. Mozilla also plans to gradually phase out access to browser features for non-secure websites, particularly features that could present risks to users’ security and privacy, he added.To read this article in full or to leave a comment, please click here

Skill Development Planning by the Dozen


I’ve been going to Cisco Live as one of the speakers for several years now. As Cisco employee, you can go to Cisco Live (for free) only if you are a speaker, or part of the World of Solutions exhibition, or if you come for the customers, or to support the network infrastructure for the event.

For the past three years at Cisco Live I’ve been sharing strategy and tips and tricks of how to become CCIE based on my own experience. My part of the session is focusing on skill development planning to achieve the objective, which is to pass CCIE lab exam. There are many technical sessions available during the event, but only very few talk about how to build learning plan and walk you through step by step of sample plan created by someone who has done it. I believe the session material can be applied outside CCIE context, and it’s relevant with my previous post, so I’m going to share it here with some updates.



Robert Grant mentioned that strategy is the means by which individuals achieve their objectives. In short, successful strategy can be achieved by having clear and consistent goal, understanding the environment Continue reading

Ultron didn’t save the world

The movie Avengers: Age of Ultron has a message for us in cybersec: In our desire to save the world, we are likely to destroy it.

Tony Stark builds "Ultron" to save the world, to bring peace in our time. As a cybernetic creation, Ultron takes this literally, and decides the best way to bring peace is to kill all humans.

The problem, as demonstrated by the movie, isn't that there was a bug in Stark's code. The problem was the hubris thinking that Stark could protect everyone. Inevitably, protecting everyone meant ruling everyone, bringing peace by force. It's the same hubris behind the USA's effort to bring peace to Iraq and Afghanistan.

I mention this because in the cybersecurity industry, there are many who propose to bring security through authority. They want government mandated rules on how to write code, imposed liability requirements, and so on.

This sounds reasonable. After all, nobody wants medical equipment like pacemakers to be hacked. But here's the thing. Computer-controlled devices have the potential to vastly improve health, whether it's Watches monitoring your heart, pacemakers, insulin pumps, and so on. While these devices can be hacked, the practical reality is that if you want Continue reading

Review: Avengers, Age of Ultron

Today was the opening of the movie "Avengers: Age of Ultron". The best way to describe it is this. On the first date, you went and saw "The Avengers". You felt the rush of something new, and you were quite satisfied. This movie, "Age of Ultron", is the second date. You already know what to expect, but that doesn't matter, because you progress past the holding-hands stage. You didn't go all the way, but you know that's coming on the third date, with "Avengers: Infinity Wars".

Remember that this movie is part of the Marvel Avengers arc, consisting of Ironman (3 movies), Captain America (2), Thor (2), Hulk, and Avengers (2). This arc also includes two TV series, and also a (so far) unrelated Guardians of the Galaxy movie. Everything is leading to the Infinity Wars movies.

I point this out because while this movie seems like a fine standalone movie for those who have seen none or only a few of the others, the greatest enjoyment will be in seeing it within context. In particular, while Ironman 3 isn't a terribly good movie, it's worth seeing before this movie, as it Continue reading

Malware campaign inflated views of pro-Russia videos

A botnet designed for Web advertising fraud was also used to nudge up the number of views of some pro-Russian videos on the website DailyMotion, according to security vendor Trustwave.An investigation into what appeared to be strictly ad fraud turned out to have a surprising political angle, wrote Rami Kogan of Trustwave’s SpiderLabs, in a blog post on Thursday.“We can’t know for sure who’s behind the fraudulent promotion of video clips, but it appears to be politically motivated,” he wrote.To read this article in full or to leave a comment, please click here

Startup launches subscription model for buying SSL certificates

A Utah-based startup has launched a subscription model for buying SSL certificates, an essential but at times onerous task.SSL and its successor, TLS (Transport Layer Security), are cornerstones of Web security, encrypting data exchanged between two machines. It underpins virtually every kind of transaction that requires privacy on the Web, from email to e-commerce. It’s signified by “https” in the URL bar of a browser.Companies and organizations are using more and more SSL certificates as the need for secure machine-to-machine communication has increased with cloud computing, virtualization and mobile devices.To read this article in full or to leave a comment, please click here

Google extends Android voice search to Zillow, Shazam, NPR

“OK Google, where are the open houses in Chicago?” That’s a question that might yield a useful response for Android users, now that Zillow’s real estate service is integrated into Google’s voice search.Several new integrations hit Google’s voice search system for Android devices on Thursday, which lets people conduct queries orally by first saying, “OK Google.” In addition to Zillow, Shazam, NPR and online radio service TuneIn have been integrated.The integrations require users to have those other apps on their smartphone or tablet. But instead of having to open the apps individually, users can ask their mobile device directly, which, hopefully, will then take them inside the appropriate app with an answer.To read this article in full or to leave a comment, please click here
