4 reasons why Spark could jolt Hadoop into hyperdrive

June 29, 2014 / / 0 Comments

Apache Spark has been winning over users since it was developed at the University of California, Berkekey, AMPLab in 2009, but it has taken on a whole new level of popularity in the last year. All of the major Hadoop distributions now support it, it’s a top-level Apache Software Foundation project and there’s a startup, called Databricks, dedicated to productizing, supporting and certifying Spark. Matei Zaharia, one of the creators of Spark and the co-founder and CTO of Databricks, came on the Structure Show podcast this week to talk about what Spark is and why people love it so much. Here are the highlights of that interview, but anyone interested in the history and capabilities of Spark, or where the big data industry might …

Meet Sher.ly, the ambitious ‘cloud’ startup that plans to destroy sync

June 29, 2014 / / 0 Comments

With two cofounders, three developers, and less than $1 million in seed funding, Sher.ly intends to bypass one of the most frustrating, ubiquitous parts of cloud storage: syncing. To accomplish that goal, Sher.ly has abandoned the cloud altogether. It sounds backwards for a cloud startup, but Sher.ly is not just local storage, explained Sher.ly chief Blazej Marciniak. The startup makes software that links devices together, enabling access to all of your files from any connected device without actually moving your data anywhere. Syncing sucks, said Marciniak in a conversation with VentureBeat. 90% of sync data is a waste of traffic and bandwidth, because you move around data you don’t really need – so we came up with a …

Stuff that Every Programmer Should Know: Data Visualization

June 29, 2014 / / 0 Comments

If you’re a programmer and you don’t have visualization as one of your main tools in your belt, then good news, you just found how to easily improve your skill set. Really it should be taught in any programming course. Note: This post won’t get you from zero to visualization expert, but hopefully it can pique your curiosity and will provide plenty of references for further study. Visualizing data has two main advantages compared to looking at the same data in a tabular form. The first is that we can pack more data in a graph that we can get by looking at numbers on screen, even more if we make our visualizations interactive, allowing explorations inside a data set. Our visual bandwidth is massive! This is …

You May Have Been A Lab Rat In A Huge Facebook Experiment

June 29, 2014 / / 0 Comments

A newly published paper reveals that scientists at Facebook conducted a massive psychological experiment on hundreds of thousands of users by tweaking their feeds and measuring how they felt afterward.In other words, Facebook decided to try to manipulate some people’s emotional states — for science.The research involved Facebook’s News Feed — the stream of status updates, photos and news articles that appears when you first fire up the site. For a week in January 2012, a group of researchers, variously affiliated with Facebook, Cornell University and the University of California, San Francisco, altered the algorithm that determines what shows up in News Feed for 689,003 people. One group was shown fewer posts containing words thought to evoke positive emotions, such as “love,” “nice” and “sweet,” while another…
