Worth Reading: Google and Latency

If you want to build infrastructure that scales larger than a single image of a server and an operating system, you have no choice but to network together multiple machines. And so, the network becomes a kind of hyper backplane between compute elements and, in many cases, also a kind of virtual peripheral bus for things like disk and flash storage. From the outside, a warehouse-scale computer, as Google has been calling them for nearly a decade, is meant to look and behave like one machine even if it most certainly is not. —Timothy Prickett Morgan @ The Next Platform

On the ‘net: Just Two Switches?

Deploying two switches provided by a vendor seems, on the surface, to be a very simple solution. The vendor’s solution is going to provide a strong suite of vertically integrated solutions, such as layer 2 overlays and link aggregation. There will only be two devices to manage, as well, which (probably) means less chance for having more than one version of code, one set of CLI commands to master. In fact, there is likely a vendor based solution at this scale that can be reduced to a “GUI and a wizard”—a simple to automate, vendor driven architecture that will reduce costs by removing the need for engineers, which can be replaced with a few administrators and the occasional visit from a consultant or vendor representative. —Search Networking

IDG Contributor Network: How the end of Net Neutrality will affect IoT

The ongoing debate over net neutrality has the internet abuzz, and for good reason; forthcoming changes to how internet service providers are regulated could fundamentally reshape the modern internet, with unknown implications for the internet of things. As the IoT continues to grow at a staggering pace, it’s important for its advocates to understand the ongoing hubbub surrounding net neutrality, and how its cessation will impact the IoT for years to come.So, what exactly is net neutrality, and what specific obstacles may spring up in the IoT’s path should it come to an end? By examining the heated ongoing debate surrounding net neutrality, IoT enthusiast can come to have an understand as to how vital a free and open internet is towards its continued success, and prepare themselves for a future where net neutrality is gone.To read this article in full, please click here

The time to deal with IoT security is now

In most cases, I try to turn a skeptical eye on hyperbole. So when a cybersecurity expert tells me that IoT security is a “ticking time bomb,” my initial reaction is not to worry about an upcoming “security apocalypse.”But I am already worried about security in the Internet of Things. So, I took the opportunity to ask Srini Vemula, global product management leader and security expert at SenecaGlobal, what’s really at risk as we hurtle toward 2020 and an estimated 20.4 billion connected devices.To read this article in full, please click here

This Holiday Season, Make Sure Your Smart Toy Isn’t a Toy Soldier

In the classic holiday story The Nutcracker, toy soldiers under command of a nutcracker spring to life to fight an army of evil mice. With the growth of smart toys, armies made up of toy “soldiers” could soon become reality. Using the same features that make them “smart,” smart toys can be taken over by outside actors and forced to do their bidding.

But rather than being led by a nutcracker to fight off evil rodents, real armies of toys could be led by criminals to attack you or me.

“Smart toys” (Internet or Bluetooth-enabled toys) are some of the most popular toys this holiday season. Internet or Bluetooth functionality enables smart toys to have amazing features. There are:

  • stuffed animals that play back messages sent from loved one’s smartphones
  • robots that teach children how to code
  • toys integrated with apps that teach reading and spelling skills while still providing physical exercise

Smart toys can do incredible things. Yet, if left unsecured, they not only present real privacy risks to the children and families who use them, but also security risks to everyone who relies on or uses the Internet.

Any Internet-connected device, be it a computer, connected thermostat, or smart toy, is at risk of being Continue reading

Worth Reading: Excel == Project Failure

Excel is comfortable. It’s our go-to software for scheduling employee time, resources for a project, lists and any other data we think needs “organization.” Chances are you already have a subscription to MS Office, you’re (at least somewhat) familiar with the interface and your customization is virtually endless. You may even have templates from past projects, so starting something new is as simple as hitting “Save As” and deleting old data. Reliable and familiar? Yes. But is it the best solution? —William Cornfield @ The Data Center Journal

Artificial intelligence may not need networks at all

The advancement of edge computing, along with increasingly powerful chips, may make it possible for artificial intelligence (AI) to operate without wide-area networks (WAN).Researchers working on a project at the University of Waterloo say they can make AI adapt as computational power and memory are removed. And indeed if they can do that, it would allow the neural networks to function free of the internet and cloud — the advantages being better privacy, lower data-send costs, portability and the utilization of AI applications in geographically remote areas.The scientists say they can teach AI to learn it doesn’t need lots of resources.To read this article in full, please click here

Juniper brings AI bots to intent-based networks

The concept of intent-based networks has received a lot of attention from media and networking professionals since Cisco launched its “Network Intuitive” earlier this year. Cisco has certainly made the term “intent-based” a household term, but that wasn’t the first time I had heard a vendor talk about this vision. Years ago, I was at an event held by Juniper Networks where its founder and CTO at the time, Pradeep Sindhu, talked about the death of Moore’s Law and how that would drive us towards this thing called intent-based networking. To read this article in full, please click here

How to extract content from compressed files on Linux

The easiest way to extract the content of compressed files (and compressed archives) on Linux is to prepare a script that both recognizes files by type and uses the proper commands for extracting their contents. Almost every compressed file will have an easily recognizable file extension — .Z, .gz, .tgz etc. And while the commands aren’t very complex, there sure are a lot of them and many options for each.So, why not attack the problem with a script that saves your precious brain cells for more challenging work? Let's look at an example that you might want to consider.To read this article in full, please click here

Data Is Not The New Oil, It’s Nuclear Power

Big Data. I believe that one phrase could get millions in venture capital funding. I don’t even have to put a product with it. Just say it. And make no mistake about it: the rest of the world thinks so too. Data is “the new oil”. At least, according to some pundits. It’s a great headline making analogy that describes how data is driving business and controlling it can lead to an empire. But, data isn’t really oil. It’s nuclear power.

Black Gold, Texas Tea

Crude oil is a popular resource. Prized for a variety of uses, it is traded and sold as a commodity and refined into plastics, gasoline, and other essential items of modern convenience. Oil creates empires and causes global commerce to hinge on every turn of the market. Living in a state that is a big oil producer, the exploration and refining of oil has a big impact.

However, when compared to Big Data, oil isn’t the right metaphor. Much like oil, data needs to be refined before use. But oil can be refined into many different distinct things. Data can only be turned into information. Oil burns up when consumed. Aside from some smoke and Continue reading
