PS, if quantum photon tangler re-danglers are activated, let me know which light on the server indicates this and how i can check to make sure the tangler is launching fresh photons.

Well, we have designed it so that the photons will automatically light up. I am particularly proud of that design.
Unfortunately, we have not exposed them outside the box so you will not be able to see them from the outside.
However, we are working on software that will represent their state in a meaningful fashion.

  • [1.] A detection of thrust that scaled with input power: the greater the power, the greater the thrust, in a predictable relationship.
  • [2.] A thrust that was at least many standard deviations above the measurement error.
  • [3.] An isolated environment, where atmospheric, gravitational and electromagnetic effects were all removed.
  • [4.] A reproducible setup and a transparent device design, so that other, independent teams can further test and validate the device/investigate the mechanism.
  • [5.] And finally, a detailed results report with the submission of an accompanying paper to peer review, and acceptance by the journal in question.

Your caveats generally cover it for me. IANAS. Perhaps I see the world through too much of a programmer perspective but #4 is the only one that I care about.
If the results are consistent and repeatable by independent groups, does anything else matter?
It depends on what you mean by "...that this is real".
If you mean, "Can I build a propulsion drive based on this principle alone?", then I would need more.
If you mean, "This demonstrates that there is a something we don't currently understand that requires further investigation", just #4.
If you mean, "Can we use this to calculate the exact improbability of this being real?" then we could feed this into a finite improbability generator (still working on it) and use it to create an Infinite Improbability Drive. Then we wouldn't need all that tedious mucking about in hyperspace.

Comment Re:without the need for doping (Score 1) 38

When a graphene sheet was placed on top of an atomically smooth sheet of yttrium iron garnet, the graphene borrowed the magnetic properties from the yttrium iron garnet and became magnetized without the need for doping.

I agree. I have had enough of hearing about all the doping scandals.
The last thing I need is news that my writing instrument is high on who-knows-what.
I can't wait to buy a pencil that will stick to my fridge without having to glue a magnet to it.
...and with two sheets built in, I won't have to hunt for paper!

Submission + - Groupon backs down on use of GNOME trademark (gnome.org)

Inzkeeper writes: The Gnome Foundation started raising funds for a court challenge after Groupon tried to register several trademarks around the name "GNOME". After an outpouring of outrage from the open source community, Groupon decided to choose a different name.

Comment Re:The film sucked; the miniseries before it was g (Score 3, Informative) 39

Each mediam was made with the author who was well aware that they are different mediums, so the stories were adapted to each medium.

Bah! You are all wrong! For the REAL die-hard fan, get a hold of the radio scripts. They add a lot of commentary on how different things came about, how he was busy scribbling details right until air time, how he grabbed the janitor at the last second to play a part he just added in. The commentary is almost as funny as the script itself.
It describes how, at the end of one episode, he threw our heros out of a space lock and had the floating in open space with seconds to live.
He then goes on the discuss how he struggled for that next week trying to decide how to free them. Anything he came up with seemed to highly improbable.
So... he came up with the Improbability Drive (tm Sirius Cybernetics).

BTW: I agree, each medium was adapted as necessary. I enjoyed all of them. At first, the movie seemed a little too slapstick for my tastes, but it quickly grew on me. I think Douglas would have approved.

User Journal

Journal Journal: Strange place

Even after 10 years of being on Slashdot, I am left to wonder what the point of a Slashdot journal is.
Who would ever look here and why?
Perhaps if this was the graveyard of rejected submissions but otherwise...?

Its stale. I've got news for you Google Street View and Satellite images can be years old. If I were relying on it for up to date information then I'd be mistaken. My house on street view was taken in 2010. A lot has changed since then.

That may be true but...
This is a logical starting point:

1. The drone snaps pictures of undocumented development.
2. Now they send in an inspector to verify and, having done so, start the process of reassessing the property.
3. Send new taxation notice
4. PROFIT!!!


Euclideon Teases Photorealistic Voxel-Based Game Engine 134

MojoKid writes Not many would argue that current console and PC graphics technologies still haven't reached a level of "photo-realism." However, a company by the name of Euclideon is claiming to be preparing to deliver that holy grail based on laser scanning and voxel engine-based technologies. The company has put together a six-minute video clip of its new engine, and its genuinely impressive. There's a supposed-to-be-impressive unveil around the two minute mark where the announcer declares he's showing us computer-generated graphics rather than a digital photo — something you'll probably have figured out long before that point. Euclideon's proprietary design purportedly uses a laser scanner to create a point cloud model of a real-world area. That area can then be translated into a voxel renderer and drawn by a standard GPU. Supposedly this can be done so efficiently and with such speed that there's no need for conventional load screens or enormous amounts of texture memory but rather by simply streaming data off conventional hard drives. Previously, critiques have pointed to animation as one area where the company's technique might struggle. Given the ongoing lack of a demonstrated solution for animation, it's fair to assume this would-be game-changer has some challenges still to solve. That said, some of the renderings are impressive.

Submission + - Fuel Cell Innovations

Inzkeeper writes: I remember years ago when I first ready about fuel cells as a possible alternative energy source.
This sounded great: using hydrogen to generate electricity without combustion. The exhaust is pure water. I was excited ...until I started reading about the drawbacks. Hydrogen is not easy to produce, store, distribute, etc. The cathode is made from platinum making it expensive.

Years after losing interest, I decided to check on recent developments in the field.
I discovered that research into the use of fuel cells is alive and well.
This may very well become the disruptive technology that we hope it could be.
Here are some of the many recent innovations out there:

April 9 2013: Burn scrap paper and aluminum, add cheap catalyst and water: "cheap" hydrogen on demand

Nov 25, 2013: CellEra creates a catalyst free of rare earth metals.

April 29, 2014: Lawrence Berkeley and Argonne National Labs create a process that uses 85% less platinum and has more the 30 times the catalytic activity.

June 24, 2014: UK's Science and Technology Facilities Council experiments with ammonia as a source fuel.
It is relatively easy to store, "cheap" to make, and can be stored at low preassure.

July 2014: GE has developed a process that uses stainless steel as a catalyst instead of platinum.
The fuel is natural gas instead of pure hydrogen. The exhaust, a mixture of hydrogen
and carbon, is then put through a combustion engine for further efficiency.

August 4, 2014: Anglo American Platinum is funding a study into the use of liquid organic hydrogen carrier (LOHC) technology
as a means of storing hydrogen.

August 22, 2014: Stanford has developed an process for producing hydrogen from water using inexpensive materials and relatively little energy.
