Big Data Knows You Had Leftover Chicken for Dinner Last Night

Big Data in the News

In just the past 15 minutes, I ran across these two unrelated articles on my #bigdata Twitter feed.

Big Data Knows What You're Doing Right Now
Wow! Twitter can tell you when you are going to get sick.

One of my favorite things about Big Data are the ridiculous blog headlines you can craft, simply by playing off the newness and lack of understanding around what Big Data is.

Take the first article for example. Time Magazine posits that aggregators are collecting a boatload of sensitive information about each and every one of us. Every time we accept a privacy policy or log in to Facebook or play an iPad app, a shadowy organization learns something new about us as individuals, powered of course by big data.

Sounds scary right?

The truth is Big Data likely doesn't have the first clue that I'm blogging about it right now. In fact, Big Data probably doesn't realize I just finished a can of La Croix Lime or that I don't really care who wins the Modern Pentathlon at the London Olympics.

I'm being flip, but the point is the overwhelming majority of information captured for use in Big Data is anonymous and likely could never be traced back to an individual. It's simply for use in the aggregate. There are plenty of worthwhile -even world changing- big data projects taking place, and most of them do not know or care that I sort of secretly enjoy the music of Maroon 5.

Now, the second story on the other hand is more than just a really great headline. Check out how aggregated Twitter data can predict, with a fairly high degree of accuracy, the prevalence of a flu outbreak.

You know you need the cloud, but you’re hesitant to simply dump everything at Amazon since you know that not all workloads are suitable for cloud. You know that you want the kind of ease of use and scalability that you get with public cloud, but your applications are architected in a way that makes the public cloud a non-starter. You’re looking at private cloud solutions based on hyperconverged infrastructure, but you’re concerned with the limits inherent in those technologies.

Most technology leaders, contemporary and from the hardware era, are reshaping their businesses to do software. They hope to capture value from emerging technologies such as IoT, SDN, and AI. Ultimately, irrespective of the vertical, it is about deriving value from independent software applications participating in an ecosystem as one comprehensive solution. In his session at @ThingsExpo, Kausik Sridhar, founder and CTO of Pulzze Systems, discussed how given the magnitude of today's application ...
The “Digital Era” is forcing us to engage with new methods to build, operate and maintain applications. This transformation also implies an evolution to more and more intelligent applications to better engage with the customers, while creating significant market differentiators. In both cases, the cloud has become a key enabler to embrace this digital revolution. So, moving to the cloud is no longer the question; the new questions are HOW and WHEN. To make this equation even more complex, most ...
As you move to the cloud, your network should be efficient, secure, and easy to manage. An enterprise adopting a hybrid or public cloud needs systems and tools that provide: Agility: ability to deliver applications and services faster, even in complex hybrid environments Easier manageability: enable reliable connectivity with complete oversight as the data center network evolves Greater efficiency: eliminate wasted effort while reducing errors and optimize asset utilization Security: imple...
Mobile device usage has increased exponentially during the past several years, as consumers rely on handhelds for everything from news and weather to banking and purchases.

The past few years have brought a sea change in the way applications are architected, developed, and consumed—increasing both the complexity of testing and the business impact of software failures. How can software testing professionals keep pace with modern application delivery, given the trends that impact both architectures (cloud, microservices, and APIs) and processes (DevOps, agile, and continuous delivery)? This is where continuous testing comes in. D

Companies are harnessing data in ways we once associated with science fiction. Analysts have access to a plethora of visualization and reporting tools, but considering the vast amount of data businesses collect and limitations of CPUs, end users are forced to design their structures and systems with limitations. Until now. As the cloud toolkit to analyze data has evolved, GPUs have stepped in to massively parallel SQL, visualization and machine learning.
