Five Things Big Data Isn’t

2273635564_840c696667_zLast week I attended a partner sales event and was dismayed (unsurprised) to learn that the confusion associated with the definition of cloud computing is logarithmically accelerated when it comes to Big Data. In many ways, I was not surprised. Big Data is not a term used in colloquial public discourse; it is one of those words buried underneath complex technology and esoteric business imperatives. You can ask the average Joe what “cloud computing” means and get one of a few dozen answers. Ask the average Joe about Big Data and you’re as likely to get a blank stare as you are a vituperative response laden with both confusion and derision. Unsurprisingly, sales guys typically hate me; I’m too nerdy and I ask too many questions. But at this event,...

Distributed NoSQL: Riak

10742693343_4d7173d61b_zIn previous post Distributed NoSQL: HBase and Accumulo, we explored two BigTable-like open source solutions. In this post we will learn about Riak, a highly available key-value store modeled after Amazon.com’s Dynamo. As we know, HBase and Accumulo provide strong consistency as a region/tablet is served by only one RegionServer/TabletServer at a time. However, this also introduces the availability problem. If a RegionServer fails, the corresponding regions will not be available during detection and recovery period. In contrast, Dynamo and Riak were designed to provide an “always-on” experience while sacrificing consistency under certain scenarios. Actually, the famous CAP theorem tells us that it is impossible for a distributed computer system to simultaneously provide all three of the following guarantees: Consistency (all nodes see the same data at the same time) Availability (a guarantee that every request receives a response...

How Your Tumblr Activity Gives Away Your Drinking Habits

TumblrAccording to Gartner, 80% of data created today is unstructured. No data could be less structured than the vast ocean of selfies, photos of Starbucks beverages and millennial angst that is Tumblr. But the billion-dollar company may have found a way to take this rich, messy cultural cachet and turn it in to something profitable for big business- by using machine learning to mine its image content for brand sentiment analysis. Tumblr have just inked a deal with Ditto, which will allow Ditto unfettered access to Tumblr’s content to scan for branded products, and sell the results to corporations like Coca-Cola, Jack Daniels- and, of course, the aforementioned Starbucks. David Rose, CEO of Ditto, discussed the deal with Motherboard. “Twitter and Instagram have been suppliers of data to us for...

Data Forecasts The Ice Bucket Challenge Will All Be Over in 22 Days

jimmy-fallon-the-roots-rob-riggle-horatio-sanz-and-steve-higgins-doing-the-als-ice-bucket-challenge-on-the-tonight-show-starring-jimmy-fallonFor those of you uninitiated with The Ice Bucket Challenge, the basic premise is as follows: a person has a bucket of ice water tipped over their head. They then nominate two friends to also tip a bucket of ice water over their head, and said friends have 24 hours to complete the challenge. Before you question this lunacy, it’s for a good cause. Any money donated goes to ALS Association, to research the motor neurone disease amyotrophic lateral sclerosis. The campaign was started by the family of Pete Frates, a baseball player who was diagnosed with ALS two years ago. The list of big names involved continues to grow- Oprah, Lady Gaga Robert Downey Jr and The Roots have all already participated. As the list of participants continues to...

60 Seconds with the Most Connected Man on Earth

article-2588779-1C8CBFA800000578-476_634x483We’re on the verge of a wearable technology revolution. Although the reception of Google Glass left a lot to be desired, hoards of companies are looking into integrating smart technology into their products- from smart watches and wristbands to home furnishings which can interact with each other. VisionGain already values the wearable tech sector at $5 billion, and that’s only set to rise. If wearable tech is the future, one man is ahead of the curve. Chris Dancy, dubbed the most connected man on earth, has approximately 300-700 applications, devices, sensors and services connected to his daily movements at any given movements. He collects an incredible amount of data that monitors everything from his blood oxygen and blood pressure levels to whether his posture is correct. Having spent over $40,000...
