Qwest Communications International Inc. is doubling its top Internet download speeds in some areas to keep up with the offerings of cable companies. The phone company said Monday it is introducing a plan with download speeds of up to 40 megabits per second and upload speeds of up to 20 mbps in parts of 15 cities, including Denver; Phoenix and Tucson, Ariz.; Salt Lake City; Seattle and Vancouver, Wash.; and Minneapolis/St. Paul
The first astronauts to walk on the moon want President Barack Obama to aim for a new destination: Mars. On Monday, the Apollo 11 crewmen, fresh from a Washington lecture Sunday in which two of them expressed concerns about NASA getting bogged down on the moon, are meeting with Obama at the White House. In one of their few joint public appearances, the crew of Apollo 11 spoke on the eve of the 40th anniversary of man's first landing on the moon, but didn't get soggy with nostalgia.
NASA's Lunar Reconnaissance Orbiter, or LRO, has returned its first imagery of the Apollo moon landing sites. The pictures show the Apollo missions' lunar module descent stages sitting on the moon's surface, as long shadows from a low sun angle make the modules' locations evident.
The technology sector is often talked about as if it were a unified front, an easy-to-define monolith. People say technology stocks rose or technology stocks fell. Tech helped drive a huge boom in the 1990s, and when that collapsed in 2001, tech contributed to the last recession. In reality, technology companies have about as much in common as Toyota Motor Corp., Boeing Co. and JetBlue Airways Corp. Sure, all three play a part in getting you places, but their customers are different, as are their sales cycles and the metrics used to measure their prospects.
The FieldFox RF Analyzer from Agilent is now available with an interference analyzer option. Key measurements include: cable and antenna test; spectrum, interference and vector network analysis; true average power measurements; and a vector voltmeter.
In a move to bolster its enterprise storage offerings, Hewlett-Packard on Friday announced an agreement to acquire IBRIX. The privately-owned company offers enterprise-class file-serving software that includes data protection, high-availability features, and data-management services for extreme scale-out, cloud and high-performance computing.
With a mission to create control ICs both for conventional and solid-state light sources, a joint development center for next-generation energy-efficient lighting technology from Dialog Semiconductor and TridonicAtco will be based in Graz and Dornbirn, Austria.

Time Domain Reflectometry (TDR) is a measurement of the impedance of a transmission line using the reflected energy of a pulse sent down that transmission line. As a pulse is sent down a transmission line, it travels at the speed of light for the media it is in (typically, 60% to 80% of the speed of light in free space). As the pulse arrives at an impedance, mismatch energy is reflected back to the pulse source and arrives at a time
