The nine most common 3D printer technologies
by Julie Sartain, March 24, 2014
Three-D printers are the hottest thing on the IT landscape. Everyone — users and vendors alike — wants a piece of this pie and, with many 3D systems now printing candy and food, they could get their wish; that is, an actual, edible piece of pie. 3D printers are the 21st century version of Star Trek’s replicators and they can, literally, print (or replicate) anything from a piece of pumpkin pie to a full-blown multi-story house. But 3D printing is not just one thing – there are many ways to do 3D printing. This slideshow illustrates the nine most common 3D printer technologies.

Can your IP address give away your identity?
by Julie Sartain, July 16, 2013
Can hackers, stalkers, criminals, and other Internet users track you down by your Internet Protocol (IP) address?
