One of the most interesting trends in the computer world during the past few years has been the rapid growth of NoSQL databases. The term may be accurate, in that NoSQL databases don't use SQL in order to store and retrieve data, but that's about where the commonalities end. NoSQL databases range from key-value stores to columnar databases to document databases to graph databases. more>>

Ideal Backups with zbackup

Data is growing both in volume and importance. As time goes on, the amount of data that we need to store is growing, and the data itself is becoming more and more critical for organizations.

Non-Linux FOSS: Animation Made Easy

If you've ever wanted to make an animated film, the learning curve for such software often is really steep. Thankfully, the Pencil program was released and although basic, it provided a fairly simple way to create animations on your computer (Windows, Mac or Linux) with open-source tools.

Android Candy: Disney Everywhere, Even Android!

As a father of three girls, I have piles and piles of Disney DVDs and Blu-rays.
