Construction needs cloud flexibility
Australia’s embattled construction sector could benefit from cloud based information systems that can be switched on and off in lockstep with individual projects – with the exception of those organisations based in remote areas like the Kimberleys.

NASA wisely lets all see images of entire sky

The WISE mission by NASA completed a full map of the entire sky over the past year. Now, NASA is releasing about half of the images sent back from the spacecraft - all for you to see.
It photographed the full sky one and one-half times over the course of its 14-month mission.
It was decommissioned on February 17, 2011, after a 10-month (cool) mission using its hydrogen coolant followed by a four-month secondary (warm) mission after the coolant ran out. The cryogenic coolant allows many of the instruments onboard to operate.
In all, over 2.7 million images were taken by WISE, including 154,000 objects within our Solar System and over 33,500 new asteroids and comets.
Out of these new asteroids and comets, 19 potentially hazardous asteroids (PHA) were discovered.
These asteroids are near-Earth asteroids (NEAs), but in addition are potentially hazardous in that they are more likely to collide with Earth (then NEAs) at some time in the future.
Page two shows where to find these images from NASA's WISE spacecraft.

Think again. Most businesses only have PART of a DR plan - and this spells business disaster in the event of an IT disaster.
