Online Dating Costs You More Privacy Than You Think

Robot Lover Thumbnail
Here’s a heads up to the millions of people looking for love on line: Your security and privacy are probably at risk. Many of the most popular dating sites are playing fast and loose with your romantic avatars. Some of them are susceptible to hackers and, to paraphrase a Microsoft cybersecurity expert, anything that you post on line is pretty much permanent after 20 minutes, whether you’ve deleted the file or not. Still feeling brave? A few more facts, then.… continue…

A New Niche for Mobile Developers

If you’re bored creating routine mobile apps and want to massively diversify your skill set, consider exploring the Internet of Things, or IoT. The Internet of Things is a parallel world of machine-to machine traffic that replaces human data input, such as touching keys on a smartphone, with sensors. The sensors take data from the physical world and connect it to the Internet via microcontrollers, small-footprint computers, radios, modems and routers. The data can then be stored on servers, acted… continue…

Romney’s ORCA: Ahab Couldn’t Have Done Better

Posted In Living in Tech
Sinking Ship
Since last week’s election, tech blogs have lit up with criticism of ORCA, Mitt Romney’s publicity-blitzed stealth app. It was touted as a high-tech game changer that supposedly would have allowed field staffers and volunteers to communicate in near-real time with Romney HQ. Through the magic of mobile, the brass would know if targeted voters in key precincts had or had not made it to the polls. If they hadn’t, the ground forces would be marshaled, hustling to get supporters… continue…

New Tools for Real-Time Processing of Big Data

Data
Here’s a little secret about how Apache Hadoop can help in processing Big Data: It does it in a batch processing mode. At present, Hadoop can’t process data in real-time, or even near real-time. What does this mean? For data that is on a file system or in some kind of storage container (like a data base), it is a matter of ingesting this data into Hadoop, then off we go doing whatever processing is necessary to produce analytic results.… continue…

The Basics of Data Dashboard Design

Busy Working Time from Bigstock Thumbnail
There are three different types of dashboard design: strategic, tactical, and operational. Each serves a different purpose and a different audience. Lee Lukehart, Chief Data Visualist for SavvyData gave us the run down in his presentation, “The Art of Dashboard Design” at the 2012 Silicon Valley Code Camp conference. Make It Work Before you let a dashboard out the door, Lukehart says think about how others will see it. If not done right, dashboards can be boring, inaccurate or even… continue…

Training Colleagues to Use the Database Correctly

Dice's Guest Appearance
by Vanessa James If you’re like most IT professionals, you spend a lot of time fixing, improving and monitoring the company database. But are we really doing everything we can to make sure the database is running at its best? We all know that the biggest database variables are the people using them. This is why we need to focus some of our time (not a lot, but some) on training employees to use the company database correctly. But let’s… continue…

How to Set Up Couchbase on a PHP Website

Couchbase
In my previous post Testing Couchbase as a NoSQL Server, I described my use of the NoSQL data store Couchbase. Today I’ll show you how to start using Couchbase with a PHP website. Note that because the Couchbase client PHP driver isn’t available for Windows, this can only be installed on a Linux system. There are two versions, the stable 1.8 or the Beta version 2.0. For this article, I used the stable version 1.8. Start by downloading and installing Couchbase.… continue…

Testing Couchbase as a NoSQL Server

WORKING - Sept. 12
At home, I’m now running an auto failover cluster of Couchbase servers. It sounds impressive, but I actually have two networked desktop PCs, one a Windows 7 and the other a Linux Mint (a popular Ubuntu-derived Distro) box, each running Couchbase and working together as one. Failover means if one server stops working, the other takes the load. The relative pros and cons of NoSQL v RDBMS (Relational Databases, e.g. MySQL) were discussed in Does Web Game Scalability Demand NoSQL? After… continue…
