Why numbering should start at zero?

How does Internet work - We know what is networking

Please note: This has nothing to do with networking in particular! Not if you look from only one perspective. If you look from totally different perspective, with Cisco ACI and all other SDN solutions, you will probably meet with Python programming language (because you will) and then, somewhere in beginning of Python exploration this is the first question that will cross your mind. Of course, if you think like me! Although not directly related to networking, the question bothered me for some time now and the answer is not only really logical when you read it but it is also

Microsoft’s HoloLens adds virtual life to Raspberry Pi 2 gadgets, robots

Microsoft says its HoloLens head-mounted computer can bring robots and gadgets based on Raspberry Pi 2 to life as they are being developed. HoloLens is an augmented-reality headset that lets users interact with 3D objects that show up as floating images, much like holographic projections. By blending computer-generated images with a user's view of the real world, Microsoft wants to change the way we interact with the environment. Microsoft also believes HoloLens can bring a new level of interactivity to enthusiasts making gadgets, robots or appliances using developer boards like the US$35 Raspberry Pi 2. The HoloLens could help makers envision how a gadget would look or how a robot would behave.To read this article in full or to leave a comment, please click here

When did you first start looking at network virtualization?

I started looking at network virtualization three to four years ago. I think before that, when it was just purely Nicira and some of those types of companies and projects, network virtualization was really the domain of the PayPals, the eBays, the Googles. Those types of companies. When VMware acquired Nicira, when Cisco did their Insieme spin-in, we started to see that commercial and traditional enterprise customers were going to have some very good options around network virtualization. We started to weigh our options and we really started to get serious about it over the last 18 months. Network virtualization ramps up right alongside our automation or orchestration practices and projects. So we believe that to do those properly, you Continue reading

Sony’s smartphone struggles continue as other areas look up

Sony’s CEO Kazuo Hirai has some difficult decisions to make as consumers continue to shun the company’s smartphones, resulting in continued losses.The company on Thursday reported a net loss of ¥126 billion (US$1.1 billion) for its latest fiscal year, which ended on March 31.

Sony has announced layoffs and pulled the plug on the PlayStation Mobile platform, but hasn’t been able to turn around its fortunes.To read this article in full or to leave a comment, please click here

Amazon buys ClusterK, a firm that helps users buy cloud capacity cheap

Amazon has acquired ClusterK, a developer of software that helps companies run mission-critical applications on spare cloud compute capacity sold by Amazon Web Services.A spokeswoman for AWS confirmed the acquisition, but did not provide further details.Spot instances are spare Amazon EC2 (Elastic Compute Cloud) instances for which users name their price. The price for the spot instances can vary in real-time depending on demand and supply. The instance will run until the spot price exceeds the bid or the user terminates it.This is in contrast with AWS On-Demand instances that let users pay for compute capacity by the hour without long-term commitments, or Reserved instances, which provide capacity reservation. AWS has positioned spot instances as the option to use when customers have flexibility in when their applications can run.To read this article in full or to leave a comment, please click here

Apple says EC probe could lead to back tax payments

Apple has warned that an European probe into its tax payments in Ireland could lead to the company having to pay disputed past taxes covering up to 10 years.The company said the impact could be “material,” but did not provide an estimate.The European Commission began a probe last year into a tax deal between Ireland and Apple to ascertain whether the taxes the company paid complied with European Union rules on state aid.The investigation would address rulings by Irish tax authorities on the calculation of the taxable profit allocated to the Irish branches of Apple Sales International and of Apple Operations Europe, to find out if the rulings involved state aid that benefited the company.To read this article in full or to leave a comment, please click here

Juniper still challenged in switching

Obscured by Juniper’s solid first quarter results were underwhelming results in its enterprise and switching businesses. Switching was off 13% from the first quarter of 2014, while the company’s enterprise business slumped about 10%.Sequentially, switching was off close to 5% and enterprise was down 2% from the fourth quarter of 2014.Still, Juniper posted a quarter that beat estimates and its own revenue and earnings guidance. The results were due to slightly better demand from cloud, cable and European service providers, and demand for routers among large enterprises, particularly those in the government vertical.To read this article in full or to leave a comment, please click here

Google develops new defense against phishing

Google has developed a new extension for its Chrome browser that aims to stop people from falling prey to phishing sites.The free Password Alert extension stores an encrypted version of a person’s password and warns if it is typed into a site that isn’t a Google sign-in page, according to a blog post on Wednesday. It will then prompt a person to change their password.Although security companies collaborate to detect and blacklist phishing sites, such attacks are commonly used by hackers to capture valuable sign-in details. Phishing sites may only be active for a short time before they’re blacklisted, but it’s still a window of risk.To read this article in full or to leave a comment, please click here

Techniques of a Network Detective

This is “Techniques of a Network Detective,” led by Denise “Fish” Fishburne (@DeniseFishburne on Twitter). Denise starts the session with a quick introduction, in which she discloses that she is a “troubleshooting junkie.” She follows up with a short description of what life looks like in her role in the customer proof-of-concept lab at Cisco.

Denise kicks off the main content of the session by drawing an analogy between solving crimes and solving network performance/behavior problems. The key is technique and methodology, which may sound boring but really have a huge payoff in the end.

When a network error occurs, the network is the crime scene. This crime scene is filled with facts, clues, evidence, and potential witnesses—or even potential suspects. How does one get from receiving notification of the problem, to asking the right questions, to solving the problem? Basically it boils down to these major areas:

  • First, identify the suspects (even if the problem seems immediately obvious). This involves gathering facts, collecting clues, following the evidence, and interviewing witnesses.
  • Next, question the suspects. Although you may not be an SME (subject matter expert), you can still work logically through gathering facts from the suspects.
  • After you Continue reading

Why the Apple Watch is in short supply

The Apple Watch launch has been somewhat peculiar insofar as Apple has limited purchases to online orders only. What's more, many consumers who were able to get their orders in won't be receiving their devices until mid-May, with some unlucky folks having to wait until June and July.So what's going on here? Isn't Apple supposed to have the best and most efficient supply chain in the business? Couldn't Apple have foreseen pent up demand for the Apple Watch and adjust supply accordingly?For weeks, there has been rampant speculation as to why the Apple Watch rollout has been so staggered. Now, thanks to a new report in The Wall Street Journal, we finally have some insight into what went down behind the scenes.To read this article in full or to leave a comment, please click here
