“Bell Labs , which has made a hobby out of 100Gbps Ethernet lately, has presented lab results that claim serial 100Gbps transmission across a 2,000km distance. Lucent divulged the results in a paper titled, “2,000-km WDM Transmission of 10 x 107Gbps RZ-DQPSK.”
Light Reading - Lucent - Lucent Stretches 100-GigE - Telecom News AnalysisThe 2000 km span was repeatered every 80 to 100 km using Raman amplifiers and the components used were normal 40Gbps components commercially available today. RZ-DQPSK modulation was used so that 100Gbps signal was actually being transmitted at 50Gbps. With DQPSK, 2 bits are transmitted with each symbol.

“A sophisticated science laboratory bound for Mars will draw its electrical power either from a nuclear generator or solar arrays, and local residents this week can weigh in on NASA’s choice.The space agency plans two public hearings today on the potential danger of launching the Mars Science Laboratory with a plutonium-powered generator, which is NASA’s preferred method of powering the craft.”

Hearings about nuclear-powered Mars probe planned

Why must we rehash the same old issue here every time a new deep space probe is launched? There have been several nuclear powered probes launched and every time we have to spend taxpayer money to debate the merits of the safety involved. Has anything changed? I am personally familiar with the safety protocols in place at Cape Canaveral and believe me. They will not launch is there is even a 0.00001 chance there will be a failure of some sort. Get over it.

Google‘ your tax dollars

President Bush said Tuesday that Americans will now be able to “Google their tax dollars,” as he signed a law to create an online database for tracking about $1 trillion in government spending on grants and contracts.

This is sure to cause mass confusion and even more political jockeying on each side of the fence. It’s a rather stupid - if not a waste of the very taxpayer money we will be able to Google - idea if you ask me.

Recording Industry vs The People

Another interesting twist in the P2P DRM saga that is the music industry. Hopefully this won’t take 3-5 years to settle. By then, we will have already lost all ownership rights. The RIAA will turn to the software model of “renting” songs to you with specific restrictions. To play a song on a CD and an MP3 player, you will need to “rent” or license the song TWICE - thus increasing their litigation coffers even more.
