A few people pointed out that Google Maps is back on iOS, which is handy if you're planning to drive to Mildura on the weekend. Navigate your world with Google Maps, now available for iPhone. Get comprehensive, accurate and easy-to-use maps with built-in Google local search, voice guided turn-by-turn navigation, public transit directions, Street View and more.
North Korea has launched a satellite, but it seems to have gone a bit wrong. The object that North Korea sent into space on Wednesday appears to be “tumbling out of control” as it orbits the earth, U.S. officials told NBC News. The officials said that it is indeed some kind of space vehicle, but they still haven’t been able to determine exactly what the satellite is supposed to do.
SilentPCReview consider a better way to compare PSU efficiency. Perhaps a better way is to analyze power inefficiency (power lost as heat) of supplies. Plotting power lost (in watts) vs. load will enable the builder to directly compare PSUs of different ratings.
Tech Report meanwhile used high-speed video to compare GeForce and Radeon. Some folks are skeptical about whether there's added value to testing with any more granularity than an FPS average would provide. Others have wondered about whether the tool we're using to grab frame time data, Fraps, really captures an accurate reflection of how frames are arriving at the display. There are some interesting questions to explored along those lines, but our intention has always been to illustrate the impact of high-latency frames on animation smoothness visually. And we can do that quite easily.
Mystro1 spotted some overclocked Dell servers. So Dell has cooked up some Linux and BIOS settings that will keep the cores revving at the top Turbo Boost speed as if this was their core frequency – even though it is not.
Lichking noticed some electronic-photonic chips from IBM. IBM has become the first company to integrate electrical and optical components on the same chip, using a standard 90nm semiconductor process. These integrated, monolithic chips will allow for cheap chip-to-chip and computer-to-computer interconnects that are thousands of times faster than current state-of-the-art copper and optical networks. Where current interconnects are generally measured in gigabits per second, IBM’s new chip is already capable of shuttling data around at terabits per second, and should scale to peta- and exabit speeds.
