Deploying Cisco traffic generator in GNS3

Goal: Deploy TRex, a realistic Cisco traffic generator, to test devices in GNS3. TRex traffic generator is a tool designed to benchmark platforms using realistic traffic. One of the tools through which TRex can be learned and tested is a virtual machine instance, fully simulating TRex without the need for any additional hardware. … The […]

Regarding automation exceptions

It can get quite exciting when you start to think about network automation and what it can do for you and your network. Once you’ve automated everything you can instead focus on deep work to evolve your business. However this daydream can soon fade away as you start to think about the things you can’t automate, or at least don’t know how to do. Ivan Pepelnjak wrote a piece about automating the exceptions. The post is based on a discussion he had with Rok Papež and his ideas about handling exceptions in an automated way.

While the strategy presented is great I think it overlooks some parts when it comes to exceptions that can arise, also the post doesn’t highlight how limitation of the configuration management tools were solved.

Petition urges Apple not to release technology for jamming phone cameras

Over 11,000 people have signed a petition asking Apple not to deploy technology that would allow third parties like the police to use it to disable cameras on user phones under certain circumstances.Apple got a patent for this infrared technology in June and bagging a patent does not necessarily mean that the company is going to use the technology in its new devices.But there is considerable anxiety that the technology that appears designed to prevent people from recording copyrighted and prohibited material could also be used by the police to remotely disable cameras that could be recording misconduct by law enforcement."The release of this technology would have huge implications, including the censoring of political dissidents, activists, and citizens who are recording police brutality," according to the petition.To read this article in full or to leave a comment, please click here

Samsung files artificial muscle patent for use in flexible smartphones

Samsung has filed two U.S. patents for a smartphone that can bend using what it calls "artificial muscle," which when voltage is applied through an internal controller can hold virtually any shape. Originally noted by Korean IT News, the first patent (US20160195902) describes a flexible display panel; a flexible image processing board that controls the video signal to the panel; and "a support member provided between the display panel and the image processing board...and at least one artificial muscle connecting at least two plates and configured to be deformed to change a shape of the support member in accordance with a voltage applied thereto."To read this article in full or to leave a comment, please click here

Google’s DeepMind A.I. can slash data center power use 40%

Google tapped into the superior intelligence of its DeepMind neural network to find ways to vastly reduce the energy it uses in its data centers, which make up 40% of the worldwide Internet."This will also help other companies who run on Google's cloud to improve their own energy efficiency," Google said in a blog about the achievement. "While Google is only one of many data center operators in the world, many are not powered by renewable energy as we are."To read this article in full or to leave a comment, please click here

Windows revenue ticks up slightly in June quarter

Microsoft yesterday reported that second-quarter revenue for its More Personal Computing division was down 4% even though Windows revenue was up over the prior year.Analysts on the company's earnings call Tuesday didn't seem to care: None of those who questioned CEO Satya Nadella or CFO Amy Hood bothered to ask about the division, Windows, or the Surface hardware -- much less about the plummeting revenue of the nearly-abandoned mobile handset strategy.More Personal Computing (MPC) -- one of three financial reporting groups -- booked revenue of $8.9 billion, off from last year's $9.2 billion. It was a return for MPC to the negative after the March quarter's revenue climbed 1%.To read this article in full or to leave a comment, please click here

Enterprise encryption adoption up, but the devil’s in the details

I was talking about security with a good friend of mine who runs a software development company. He’s a really smart, technology-savvy guy but his take on encryption wasn’t positive. While he completely understands the need, he hates encryption (and security in general) because he says it always gets in the way when he’s trying to get work done. In this respect, I don’t think he’s that different from most people in the high tech world or, indeed, in the business world in general. This general dislike of encryption is because encryption doesn’t seem valuable when it’s a virtual speed bump in the road to getting stuff done and its benefits, despite the huge increase in breaches and hacking, are hard to quantify. So, with the exception of the paranoid and security geeks, encryption has traditionally been seen as a belt added to the braces of other simpler and therefore more tolerable security measures.To read this article in full or to leave a comment, please click here

Intel ships Kaby Lake chips, pointing to PC availability in a few months

Tablets and laptops with Intel's 7th Generation Core chips code-named Kaby Lake should become available in the coming months.Intel is shipping Kaby Lake chips to PC makers now, CEO Brian Krzanich during Intel's earnings call Wednesday. Systems with new processors usually become available a few months after Intel delivers the chips.Kaby Lake will succeed current Core processors named Skylake. The new chip has the underpinnings of Skylake and won't necessarily be smaller in size, but it'll provide speed improvements over its predecessor, Krzanich said.That raises a question: should you wait a few months for Kaby Lake instead of upgrading to a Skylake PC now? Experts generally say you should buy a PC as and when you need it rather than wait for the next improvement to come along.To read this article in full or to leave a comment, please click here

2016 Cisco Live, US – Geeks for life. — Just another day at the office…

CiscoLive 2016 LasVegas was my absolute favorite CiscoLive EVER!  They just keep getting better and better and better every year!  I so adore my “Nerd Herd” friends.

I was going to write a blog.. but I just couldn’t find the words……

So please enjoy my friend’s blog (@amyengineer) reblogged here. ?

Fish  ?

Putting together a wrap up post on Cisco Live US always makes me smile, and 2016 is no exception. As many of you know, this CLUS marked 5 years since Tom and a small group of engineers first bonded over networking nerdiness and an addiction to 140 characters. We’ve followed and helped each other through […]

Intel profit slides on costs related to layoffs

Intel's profit dropped sharply last quarter due to heavy costs from a restructuring announced in April, though sales were up thanks to the company's powerful data center group.Intel's profit for the quarter, ended July 2, was $1.3 billion, down from $2.7 billion a year earlier, the company announced Wednesday. Revenue climbed 3 percent to $13.5 billion.Intel said in April that it would axe 12,000 jobs worldwide, or 11 percent of its staff, in a plan to cut costs and focus on growing businesses like server processors and chips for the internet of things.In the process, it canceled the development of low-power Atom processors and more or less gave up on the smartphone and tablet markets -- areas where it's never done well.To read this article in full or to leave a comment, please click here

Wireless on wheels? Cable can play at that game, too

When lots of people gather for concerts or sports events, cellular carriers often bring their networks to the scene with cell towers mounted on trucks, or COWs (cells on wheels). Not to be outdone, Comcast is joining the fray using Wi-Fi.The U.S. cable giant will bring WoW (Wi-Fi on Wheels) to the Democratic National Convention in Philadelphia next week. WoW is what it sounds like: a van with six access points (APs) mounted on a 40-foot mast.Each AP points in a different direction so the truck can deliver strong signals over a wide area. It can serve as many as 3,000 people within a range of 500 feet, according to Comcast. Those users can get speeds as much as five times as fast as cellular, the company says.To read this article in full or to leave a comment, please click here
