It's not every day that a new mobile operating system arrives, but Tuesday will be one of them as Telefonica begins selling the inexpensive ZTE Open with Mozilla's Firefox OS in Spain.

The move marks the commercial beginning of an effort by phone makers and network operators to use Mozilla's open-source, browser-based operating system to reclaim power in the mobile market lost to Apple and Google.

The phone itself costs 69 euros ($90), including 30 euros ($39) of pay-as-you-go credit -- or for those who sign up for a two-year contract, for 2.38 euros ($3.10) … Read more

Review: Reconciliation on Fire works with Excel to provide a good comparison tool

Reconciliation provides a valuable tool to reconcile differences between data in different Excel sheets or tabs with the click of a button. Designed as a macro for Excel 2010, it will rapidly search and present discrepancies in large data sets in your spreadsheets, matching any two sets of cells.

This is not a traditional software tool so much as a macro for Excel, allowing you to compare large data sets. The act of doing so can be time consuming on its own, and this macro speeds it up many times over. Installation is not required. Simply open the macro and … Read more

Turn your Kindle Fire into an Android 4.2 tablet

For a long time I've been a fan of N2A Cards, which sells a simple plug-and-play way to turn Barnes & Noble's Nook tablets into full-blown Android tablets. After all, if you've got good hardware, why not unlock its maximum potential?

Now Kindle owners can get in on the action. N2A's new N2Aos service will install Android 4.2 (Jelly Bean) on your first- or second-generation Kindle Fire, replacing Amazon's heavily customized -- and, some would say, limited -- operating system with the real deal.

There are, of course, a few important considerations.… Read more

Nook HD vs. Kindle Fire HD

It's a Prizefight punch-out! The 7-inch tablet has established itself as the sweet spot for size and price, so we're facing off the recently updated Barnes & Noble Nook HD and the Amazon Kindle Fire HD!

Which is your pick to be the Prizefight King of the Ring? Barnes & … Read more

Best Buy recalls MacBook Pro replacement batteries due to 'burn hazards'

After a U.S. government agency received 13 reports of battery fires, including one that caused a "serious burn" to the user's leg, Best Buy has decided to recall thousands of replacement batteries for Apple's MacBook Pro laptops.

Those batteries being recalled are both the black and white ATG replacement batteries … Read more

Experimenting with fireballs in space

Here on planet Earth we're used to flames -- whether from a candle or campfire -- reaching upward to the sky with slender limbs hungry for oxygen and driven by rising hot air. But in space, sans our planet's strong gravitational pull, flames are more likely to take the shape of eerie fireballs.

Within the flame of a regular candle wick, there's quite a bit going on. As the video below released this week by NASA explains, molecules from the wick are being cracked apart and vaporized by the flame, then combined with oxygen to produce light, heat, carbon dioxide, and water, as well as soot.

In recent years we've become quite familiar with how flames can extend and expand quickly in their greedy quest for more fuel and oxygen; witness countless western wildfires of the past decade. But researchers aboard the International Space Station have observed that flames in microgravity behave much differently, staying in a small spherical shape and letting oxygen molecules come to them.… Read more

Segway-like robot helps fight fires with 3D, thermal imaging

In 2012, 83 firefighters died in the line of duty in the U.S. alone, and another 37 fatalities have been reported thus far in 2013. But, with better scouting tools, these numbers could be lowered.

Thank goodness for robots.

A new one out of the University of California, San Diego, may soon help first responders survey a fiery scene with its ability to enter a burning building and immediately transmit data on the state and location of the fire, the building's structural integrity, and the presence of any volatile gases -- all while on the lookout for survivors.… Read more
