Comment Re:Frame of Reference Problem (Score 1) 454

well, the fact that you need to reach 88mph suggests that whatever mechanism is being used for this time travel is somehow intrinsically linked to the earth's gravitational field.
We know that there is a relationship between space-time and gravity so it is fairly reasonable to presume that gravity fields might be a significant factor in a time travel device's operation... it would also explain the 'spatial problem' of the earth being in a different location at different times. If the nearest significant gravitational space-time distortion is a kind of axis around which a device could swing through time....
I mean... something has to be the base spatial reference... since there is no universal spatial reference point it makes a lot sense to use the closest gravity well.

Recommendations For Home Virtualization? 384

An anonymous reader writes "I'll have to upgrade my home computers sometime in the next few months and I'm thinking it's time to swallow the virtualization pill. Besides the ease of switching between Windows and Ubuntu, I'm looking mainly for the ability to save machine state in order to be able to revert to a known working state. Googling turns up mostly guides from 2009 and earlier. Is VMWare ESX pretty much the way to go? Performance does matter — not for gaming but I am heavily into photography, so apps like Lightroom and Photoshop need to run well. Thanks for any insight."

*sigh*
It *is* a very reasonable point that he is making.
The growing significance of virtual domains and the significance of the relationships we develop there is a big and growing issue.
It is something we should be thinking about if we want to help shape our future instead of simply going with the flow.

Sadly I doubt the slashdot crowd will be able to get over the ridiculousness of the pope saying this.

Many More Android Apps Leaking User Data 299

eldavojohn writes "After developing and using TaintDroid, several universities found that of 30 popular free Android apps, half were sharing GPS data and phone numbers with advertisers and remote servers. A few months ago, one app was sending phone numbers to a remote server in China but today the situation looks a lot more pervasive. In their paper (PDF), the researchers blasted Google saying 'Android's coarse grained access control provides insufficient protection against third-party applications seeking to collect sensitive data.' Google's response: 'Android has taken steps to inform users of this trust relationship and to limit the amount of trust a user must grant to any given application developer. We also provide developers with best practices about how to handle user data. We consistently advise users to only install apps they trust.'"
