Submission + - Using Pulsars As GPS - A Space Navigation System Fit For A Starship? (sciencecodex.com)

cold fjord writes: Science Codex reports, "CSIRO scientists have written software that could guide spacecraft to Alpha Centauri, ... Dr George Hobbs (CSIRO) and his colleagues study pulsars — small spinning stars that deliver regular 'blips' or 'pulses' of radio waves and, sometimes, X-rays. Usually the astronomers are interested in measuring, very precisely, when the pulsar pulses arrive in the solar system. Slight deviations from the expected arrival times can give clues about the behaviour of a pulsar itself, ... "But we can also work backwards," said Dr Hobbs. "We can use information from pulsars to very precisely determine the position of our telescopes." "If the telescopes were on board a spacecraft, then we could get the position of the spacecraft." Observations of at least four pulsars, every seven days, would be required. ... A paper (paywalled) describing in detail how the system would work has been accepted for publication by the journal Advances in Space Research." Related story.

Submission + - Move Over Samsung Galaxy Gear, Omate TrueSmart Watch Is Here (gizmobeast.com)

jarold writes: Move over Samsung Galaxy Gear, Omate TrueSmart watch is here. Dubbed as the world’s first standalone smartwatch, it can work independently from smartphone. Omate TrueSmart has started production after raising more than $100,000 through Kickstarter crowdfunding.
The biggest selling point for Omate TrueSmart is its ability to make voice calls, text and social media messaging without a smartphone or tablet. As with other smartwatches in the market, it can be paired with a smartphone for notifications, access to apps and more. The developers even suggested it can work with Google glass to optimize smart wearable technology experience.

Elaborate. There has never been a difference. If the NSA overhears you talking about buying a brick of weed, they send that to the DEA, who does some parallel construction to find another reason to pull you over. Why wouldn't they cooperate? Do you have any reason to think that they didn't in the past?

Perhaps a better question is, if the FBI obtains a warrant to "wiretap" would that give them justification to do a narrow search on the pool of data already collected. Probably true that the collected data couldn't be used to initiate an investigation, but if the investigation is initiated through other means, what does that mean?

That's not exactly true. You might get a single scan or two, but large services who have farms can easily have a firewall that interconnects an array of different IP's. When a syn is left hanging an IPS can easily craft a rule to block further connections from that address. So you'll get a few replies, but you'll miss the rest. Likewise, there are services out there (ISC?) that track such activities and site block abusive IP's based on netflows. If someone employed this scanner, they'll likely hit the radar. But a good question is what happens when a few hundred thousand people hit this, or folks who come off of major proxy servers that are normally whitelisted... Oh yes, much interestingness can develop from this tool...

I'm not questioning the rightness or wrongness of the program. That's still very much up for debate, both through official channels and the general public, and no doubt and in no small part on Slashdot. That was the whole intent of why Snowden did what he did. But what I am mentioning is that the reason the program was classified as Top Secret is because releasing the information (which Snowden did) would cause exceptional harm to the US. ... $160B in damage in my book is definitely exceptional.
