An NEC study found that people who use dual monitors were 44 percent more productive.

Having at least two computer monitors (or more!) is one of the best business productivity tools you can have along with a fast computer and an 8-button mouse. In fact, an NEC study at the University of Utah found that people who used dual monitors were as much as 44 percent more productive at certain text-editing operations than people using a single monitor.Read More

Core i7 Reference Guide
Build It Or Buy It? A Practical Guide for an i7-920 Computer with 12GB Memory and Windows 7 for under $1,000
$1,000 i7 Desktop Computer

The Core i7 is Intel's monster processor that everybody seems to be talking about, but is the Ferrari of processors really worth the price?

We wanted to see what all the i7 excitement was about, so we decided to take the plunge based on the following criteria: It had to be screaming fast, upgrade compatible (1366 socket), and relatively low cost. After some research, we learned that an i7-920 would be the best i7 computer to meet our requirements - and to our surprise - could be built OR purchased on a budget of less than $1,000.

Make sure you start with a Core i7-9xx series (1366 socket) processor. Other i7s like the i7-860/870 use the 1156 socket and are not upgrade compatible.

An i7 computer needs three essential ingredients that generally aren't lying around in the garage: (1) an i7-900 series processor (like the entry-level i7-920); (2) an Intel X58 chipset-compatible motherboard, and (3) lots of DDR3 memory. Knowing what we needed, we then had to decide whether to build it - or buy one off the shelf.

The decision turned out to be an easy one after we found a Core i7-920 workstation at Costco loaded with a jaw-dropping 12GB of DDR3 memory, 1TB SATA hard drive, and Windows 7 - all for $999 delivered.Read More

Cell Phone Car Starter

Fed up with his frigid car, Aaron installed a remote starter to warm the car up before he got to it. This didn’t help at his work because his car was parked several hundred feet from his office - outside the range of his OEM starter. Aaron decided to make his starter work with GSM so he could start his car with a phone call from any distance.Read More

How to Weave Glass

How to Weave Glass

Weaving is an art that assumes the materials used are flexible. The trick to weaving glass is to warp a set of sticks that are pre-formed into a series of curves that fit together to create figure-eight shapes. Once the warp is shaped, it is a simple matter to slip the weft threads into place by inserting them into the holes of the figure eights from the side.Read More
