Comment Re:Ship landing? (Score 1) 115

The point is to recover the stage for easy future use. How easy will it be to reuse a stage which has been floating in the sea for several hours (minimum).

Also, a longer term plan is to be able to touch down on land, the sea provides a good environment to practice soft landings because when you fail you are a really long way from any people/infrastructure and because with the motion of the landing ship, once you can reliably do sea landings, surface landings should be relatively easy

Also the reason for an ocean based landing is so the booster does not have to do a U turn to come back to the take off location. This means that Space-X can launch a larger payload because they don't need as much fuel for the return. Or do it cheaper.

Submission + - Ask Slashdot: How to improve today's standard protocols?

An anonymous reader writes: I have an idea for an improvement for the BitTorrent protocol that I call "metatorrents" and basically involves torrents "borrowing" files and seeds from other, better seeded torrents. I probably could implement it myself for one of the popular clients, but it's a lot of work and I don't even really know if it would take on. How could I get help changing something in the Internet's core?

Submission + - Ansel Adams Act Would Allow Photographs in Public Spaces (congress.gov) 1

davidannis writes: Photographers have been harassed for taking pictures in public places since 9/11. One was arrested for participating in an Amtrak contest. The park service is charging fees. Representative Steve Stockman (R, Texas) addresses the problem with the Ansel Adams Act which he introduced today. It says "It is contrary to the public policy of the United States to prohibit or restrict photography in public spaces, whether for private, news media, or commercial use." The act prohibits government agencies from prohibiting photography for National Security Reasons without a court order, from charging photographers fees, and prohibits equipment from being confiscated.

Federal law enforcement officers or private contractors shall not seize any photographic equipment or their contents or memory cards or film, and shall not order a photographer to erase the contents of a camera or memory card or film.


Submission + - Ford touts self-driving car, launches global mobility experiments

An anonymous reader writes: Ford showcased the semi-autonomous vehicles it has on the road at CES and gave attendees a glimpse into fully autonomous vehicles now in development. The carmaker also announced a series of experiments with drivers around the globe to test its vehicle-to-vehicle connectivity, autonomous cars and the use of big data collected from vehicles. The company said a fully autonomous Ford Fusion Hybrid research vehicle is undergoing road testing now. The vehicle relies on the same semi-autonomous technology used in Ford vehicles today, while adding four LiDAR (light, radar) sensors to generate a real-time 3D map of the surrounding environment.

Submission + - mathematical universe and the hard problem of consciousness (wordpress.com)

An anonymous reader writes: In the beautiful words of David Chalmers – consciousness poses the most baffling problem in science. There is nothing that we know more intimately than conscious experience, but there is nothing that is harder to explain. All sorts of phenomena have yielded to scientific investigation in recent years, but consciousness has stubbornly resisted. Many have tried to explain it, but the explanations always seem to fall short of the target. Some have been led to suppose that the problem is intractable, and that no good explanation can be given.

I am sorry — the article is not very short, so please go to the source http://theproblemofconsciousne...

Submission + - How many habitable planets are in our galaxy?

StartsWithABang writes: For the past three years, Kepler has been looking at 150,000 stars, searching for planetary transits. The science haul has been huge, but mostly larger planets close in to their parent stars. Nevertheless, a few rocky, habitable-zone planets have been discovered. Whether we take optimistic or pessimistic estimates, what do we expect for the rest of the galaxy? At minimum, some 6 billion habitable-zone, rocky planets. And likely many more!

Submission + - Hecker: The real threat from North Korea: not cyber attack, but nuclear bombs (thebulletin.org)

Lasrick writes: Sig Hecker is director emeritus of the Los Alamos National Laboratory, where he served as director from 1986 to 1997 and as senior fellow until July 2005. He has traveled to North Korea seven times over the last decade, and is one of the only scientists to have seen their nuclear facilities first-hand. He describes the trajectory of North Korea's nuclear program since the Reagan administration, and points out that the real threat from DPRK remains its nuclear arsenal: 'The absurdities in The Interview, North Korea’s alleged retaliatory cyber-attack on Sony Pictures Entertainment, and US counter-threats and sanctions may be worthy of analysis, but when it comes to the real threat that Pyongyang poses to the world, they amount to no more than a giant distraction.' Terrific read.

It is possible, and it has been done. But it takes a specialized organism (bacteria, maybe frogs, some insects) or some way to prevent ice crystal formation... And a mammoth dis not have this advantage. Your references require some quite advanced technology that was not around (that I know of) 43000 years ago. A nicely frozen steak is not viable tissue.
