Turn on FileVault to encrypt the drive. Set a firmware password. Make sure there are no guest accounts. See and . Turn off iCloud and don't enter an AppleID. Use an encrypted text editor on top of this with a 3rd password. This won't stop the NSA, but will stop most hack attempts. Putting documents on an encrypted SD card is not a bad idea.

Submission + - The scandal of fiddled global warming data: US has been cooling since the 30s (

schwit1 writes: When future generations try to understand how the world got carried away around the end of the 20th century by the panic over global warming, few things will amaze them more than the part played in stoking up the scare by the fiddling of official temperature data. There was already much evidence of this seven years ago, when I was writing my history of the scare, The Real Global Warming Disaster. But now another damning example has been uncovered by Steven Goddard’s US blog Real Science, showing how shamelessly manipulated has been one of the world’s most influential climate records, the graph of US surface temperature records published by the National Oceanic and Atmospheric Administration (NOAA).

Goddard shows how, in recent years, NOAA’s US Historical Climatology Network (USHCN) has been “adjusting” its record by replacing real temperatures with data “fabricated” by computer models. The effect of this has been to downgrade earlier temperatures and to exaggerate those from recent decades, to give the impression that the Earth has been warming up much more than is justified by the actual data. In several posts headed “Data tampering at USHCN/GISS”, Goddard compares the currently published temperature graphs with those based only on temperatures measured at the time. These show that the US has actually been cooling since the Thirties, the hottest decade on record; whereas the latest graph, nearly half of it based on “fabricated” data, shows it to have been warming at a rate equivalent to more than 3 degrees centigrade per century.

Comment Signal jamming, friend or foe (Score 2) 622

Drones can be hacked. Their signals jammed or spoofed. Their satellites destroyed. Their home bases attacked or infiltrated. They work very well against low tech enemies like Iraq and Afghanistan. Against the Russians or Chinese it would be a different matter, especially when the chips in a drone originate in China. War is an ever-changing game where every move has a countermove. The nice thing about human pilots is that they understand their orders and the underlying reasons for those orders. They can change their minds quickly and use situational information that drones would lack.

I'm not sure that g-force matters all that much in an era of smarter, faster missiles. When was the last real movie-style dogfight?

On the other hand, there is no question that drones are useful and will continue to improve at a rapid pace. Eventually they will replace most of our planes. With longer flight times we might be able to replace half of our aircraft carriers with land-based drones, but the inevitable cost overruns won't magically disappear.
