Now Cisco can even network your building systems

The latest network hardware from Cisco Systems gives new meaning to the words “light switch.”The Catalyst Digital Building Series Switch is an Ethernet switch designed to link different kinds of building infrastructure over a network. It will be available worldwide in the second quarter. It uses Cisco’s enhanced version of PoE (Power over Ethernet) to run things like lights and cameras while collecting data about those devices over the same standard cable.The switch embodies the merger of IT and OT (operational technology), one of the big enterprise trends that the internet of things is driving. The line is blurring between information systems like servers and building systems like lighting, heating, and physical security. The new technology could make buildings run better. It might also help to turn IT folks and facilities experts into a bit of both.To read this article in full or to leave a comment, please click here

Apple’s Mobility Partner Program comes out of hiding

You won’t find many public references by Apple to its Mobility Partner Program, an expanding effort by the company to unite with software developers/integrators to boost sales of iPhones and iPads to businesses. In fact, Apple reportedly has discouraged partners in years past from discussing MPP out in the open.But the veil of secrecy surrounding the program is thinning. Apple’s public relations department didn't acknowledge my queries about MPP, such as how long the program has actually been around. But CEO Tim Cook has begun citing the program during Apple (AAPL - NASDAQ) earnings calls over the past year: He specified in October that more than 120 partners have signed on worldwide, and that’s up from about 90 at the start of the year. To read this article in full or to leave a comment, please click here

Response: BGP in 2016 – Geoff Huston

Geoff Huston taking a withering look at the crapness of BGP in the Internet. As always, its quite crap excluding the fact that it actually works (more or less).

It has become either a tradition, or a habit, each January for me to report on the experience with the inter-domain routing system over the past year, looking in some detail at some metrics from the routing system that can show the essential shape and behaviour of the underlying interconnection fabric of the Internet.

The long predicted apocalypse in the Internet routing table hasn’t come to pass so the those 15-year old Catayst 6500 switches will still be used in the Internet backbone for many years to come. Oh, yay.

None of the metrics indicate that we are seeing such an explosive level of growth in the routing system that it will fundamentally alter the viability of carrying a full BGP routing table anytime soon. In terms of the projections of table size in the IPv4 and IPv6 networks, the BGP sky is firmly well above us, and it’s not about to fall on our heads just yet!

Managing Network Services Configuration with Ansible

In the last few weeks I’ve seen numerous questions along the lines of “how do I manage VLANs on my switch with Ansible”. You can look at this question from two perspectives: the low-level details (which modules do I use, how do I push commands to the box…) or the high-level challenges (how do I make sure actual device state matches desired device state). Obviously I’m interested in the latter.

Apple crosses Samsung in smartphone market, helped by Note7 debacle

Apple has regained the top place in the smartphone market helped by the new iPhone 7 and 7 Plus, while rival Samsung Electronics grappled with the recall of its flagship Galaxy Note7 over overheating batteries, according to a research firm.The iPhone maker shipped 78.3 million smartphones in the fourth quarter for a market share of 17.8 percent in comparison to 77.5 million smartphones shipped by Samsung, which had a market share of 17.7 percent, Strategy Analytics said Tuesday.For the full year, Samsung was the clear winner with shipments of 309.4 million smartphones to Apple’s 215.4 million, in part because Apple saw shipments of the iPhone drop in recent quarters.To read this article in full or to leave a comment, please click here

How to make PC security alerts better? Make them twirl, jiggle

Have you ever ignored a security alert on your PC? You’re not the only one.The warnings are designed to save us from malware infections and hacking risks, but often times we’ll neglect them. It could be because we’re too busy or we’ve seen them too many times, and we've become conditioned to dismiss them -- even the most serious ones, according to Anthony Vance, a professor at Brigham Young University.Vance has been studying the problem and he’s found that introducing certain small, but noticeable changes, can make the alerts more useful and harder to ignore.  "Our security UI (user interface) needs to be designed to be compatible with the way our brains work," he said at the USENIX Enigma 2017 conference on Tuesday. "Not against it."To read this article in full or to leave a comment, please click here

Anuta Networks NCX: Overcoming Skepticism

Anuta Networks demonstrated their NCX network/service orchestration product at Network Field Day 14.

Anuta Networks page at TechFieldDay.com with videos of their presentations

Anuta's promise with NCX is to provide a vendor and platform agnostic network provisioning tool with a slick user interface and powerful management / provisioning features.

I was skeptical, especially after seeing the impossibly long list of supported platforms.

Impossible!
Network device configurations are complicated! They've got endless features, each of which is tied to others the others in unpredictable ways. Sure, seasoned network ops folks have no problem hopping around a text configuration to discover the ways in which ACLs, prefix lists, route maps, class maps, service policies, interfaces, and whatnot relate to one another... But capturing these complicated relationships in a GUI? In a vendor independent way?

I left the presentation with an entirely different perspective, and a desire to try it out on a network I manage. Seriously, I have a use case for this thing. Here's why I was wrong:

Not a general purpose UI
Okay, so it's a provisioning system, not a general purpose UI. Setup is likely nontrivial because it requires you to consider the types of services Continue reading

According to the U.S. Department of Labor, a bad hire costs at least 30% of the initial annual salary, but that number is believed to be much higher.

Meet the $114,725 Ubuntu server with eight Nvidia Tesla P100 GPUs

The Ibex Pro is one supercharged machine that will probably hurt your electric bill.System76's fastest Ibex Pro with Ubuntu Server 16.10 packs some crazy horsepower with Intel's latest 22-core Xeon E5 v4 chips and eight Nvidia Tesla P100 graphics processors.It's got the same number of GPUs as Nvidia's superfast DGX-1, which is being used for deep learning. System76 is targeting the Ibex Pro -- which is a rack server -- at the same market as the DGX-1. The server has fewer, but newer, CPUs, compared to the DGX-1.An entry-level Ibex Pro priced at US $9,575 will run Ubuntu Server 16.10, with a six-core Intel Xeon E5-2603v4 chip, 16GB of memory, a Tesla K40 GPU, and 250GB of storage.To read this article in full or to leave a comment, please click here
