Rising to 634.0 metres (2,080 ft), it is the second-tallest structure in the world, after the Burj Khalifa. Completion was delayed two months due to the effects of the 2011 Japanese earthquake and tsunami."
dtmos writes "The ARRL is reporting that "delegates attending the 2012 World Radiocommunication Conference (WRC-12) in Geneva have approved a new 7-kilohertz-wide secondary allocation between 472-479 kHz for the Amateur Radio Service." This band, below the AM broadcast band, will retain its primary ship-to-shore and radionavigation beacon allocation. Due to the unique propagation characteristics of this part of the spectrum, an allocation has long been desired by the amateur radio community. Much as moonbounce and meteor scatter have produced their own amateur digital communication protocols (OSS under the Gnu GPL, of course), I expect the unique channel impairments of this band will lead to the development of dedicated digital communication schemes (beyond QRSS)."
dtmos writes "Spaceweather reports "A coronal mass ejection (CME) hit Earth on Oct. 24th at approximately 1800 UT (2:00 pm EDT). The impact strongly compressed Earth's magnetic field, directly exposing geosynchronous satellites to solar wind plasma, and sparked an intense geomagnetic storm. As night fell over North America, auroras spilled across the Canadian border into the contiguous United States." Aurora were seen as far south as Baileyton, Alabama."Link to Original Source

dtmos writes "This summer, 'Starcraft II' has become the newest barroom spectator sport. Fans organize so-called Barcraft events, taking over pubs and bistros from Honolulu to Florida and switching big-screen TV sets to Internet broadcasts of professional game matches.
As they root for their on-screen superstars, "Starcraft" enthusiasts can sow confusion among regular patrons ... But for sports-bar owners, "Starcraft" viewers represent a key new source of revenue from a demographic—self-described geeks—they hadn't attracted before."Link to Original Source
dtmos writes "The U.S. Defense Advanced Research Projects Agency (DARPA) has announced that its Falcon Hypersonic Technology Vehicle 2 (HTV-2) flight on Thursday, 11 August, "experienced a flight anomaly post perigee and into the vehicle’s climb. The anomaly prompted the vehicle’s autonomous flight safety system to use the craft’s aerodynamic systems to make a controlled descent and splash down into the ocean."
“According to a preliminary review of the data collected prior to the anomaly encountered by the HTV-2 during its second test flight,” said DARPA Director Regina Dugan, “HTV-2 demonstrated stable aerodynamically controlled Mach 20 hypersonic flight for approximately three minutes. It appears that the engineering changes put into place following the vehicle’s first flight test in April 2010 were effective. We do not yet know the cause of the anomaly for Flight 2.”"Link to Original Source

The number RSA-768 was taken from the now obsolete RSA Challenge list as a representative 768-bit RSA modulus. This result is a record for factoring general integers. Factoring a 1024-bit RSA modulus would be about a thousand times harder, and a 768-bit RSA modulus is several thousands times harder to factor than a 512-bit one. Because the first factorization of a 512-bit RSA modulus was reported only a decade ago it is not unreasonable to expect that 1024-bit RSA moduli can be factored well within the next decade by an academic effort such as ours . . . . Thus, it would be prudent to phase out usage of 1024-bit RSA within the next three to four years.
