Submission + - All Flags on the Moon Have Turned White (spaceindustrynews.com)

An anonymous reader writes: Since the United States landed on the Moon on July 20th 1969, there has been an American flag standing on its surface. While 5 out of the 6 flags still stand (Neil Armstrong reported that Apollo 11s flag was knocked over by engine thrust), the colors of Old Glory have faded due to the Suns harsh radiation.

Submission + - Lawmakers of both parties voice doubts about NSA surveillance programs (metasploit.it)

anontoworld writes: Washington Post: Cole said the programs are legal and overseen by the Foreign Intelligence Surveillance Court. He also said the programs “achieved the right balance” between protecting Americans’ safety and their privacy.

“Both programs are conducted under laws passed by Congress,” Cole said.

The 11 judges on the secret FISA court that approves surveillance “are far from rubber stamps,” he said. “They don’t sign off until they are satisfied that we have met all statutory and constitutional requirements.”

But some lawmakers were not swayed by Cole’s explanation.

Submission + - Evolution of interplanetary trajectories reaches human-competitive levels (esa.int)

LFSim writes: It's not the Turing test just yet, but in one more domain, AI is becoming increasingly competitive with humans. This time around, it's in interplanetary trajectory optimization.

From the European Space Agency comes the news that researchers from its Advanced Concepts Team have recently won the Gold "Humies" award for their use of Evolutionary Algorithms to design a spacecraft’s trajectory for exploring the Galilean moons of Jupiter (Io, Europa, Ganymede and Callisto).

The problem addressed in the awarded article was put forward by NASA/JPL in the latest edition of the Global Trajectory Optimization Competition. The team from ESA was able to automatically evolve a solution that outperforms all the entries submitted to the competition by human experts from across the world.

Interestingly, as noted in the presentation to the award's jury, the team conducted their work on top of open-source tools (PaGMO / PyGMO and PyKEP).

Submission + - Ask Slashdot: What Is The Most Painless Intro To GPU Programming? 3

dryriver writes: Dear Slashdotters. I am an intermediate level programmer who works mostly in C# NET. I have a couple of image/video processing algorithms that are highly parallelizable — running them on a GPU instead of a CPU should result in a considerable speedup (anywhere from 10x times to perhaps 30x or 40x times speedup, depending on the quality of the implementation). Now here is my question: What, currently, is the most painless way to start playing with GPU programming? Do I have to learn CUDA/OpenCL — which seems a daunting task to me — or is there a simpler way? Perhaps a Visual Programming Language or "VPL" that lets you connect boxes/nodes and access the GPU very simply? I should mention that I am on Windows, and that the GPU computing prototypes I want to build should be able to run on Windows. Surely there must a be a "relatively painless" way out there, with which one can begin to learn how to harness the GPU?

Submission + - Ask Slashdot: Scientific Research Positions for Programmers?

An anonymous reader writes: I recently (within the past couple years) graduated from college with a bachelor's degree in Computer Science and currently work as a programmer for a large software consulting firm. However, I've become gradually disillusioned with the financial-obsession of the business world and would like to work for the overall betterment of humanity instead. With that in mind, I'm looking to shift my career more toward the scientific research side of things. My interest in computer science always stemmed more from a desire to use it toward a fascinating end — such as modeling or analyzing scientific data — than from a love of business or programming itself. My background is mostly Java, with some experience in C++ and a little C. I have worked extensively with software analyzing big data for clients. My sole research experience comes from developing data analysis software for a geologic research project for a group of grad students; I was a volunteer but have co-authorship on their paper, which is pending publication.

Is it realistic to be looking for a position as a programmer at a research institution with my current skills and experiences? Do such jobs even exist for non-graduate students? I'm willing to go to grad school (probably for geology) if necessary. Grad school aside, what specific technologies should I learn in order to gain an edge? Although if I went back to school I'd focus on geology, I'm otherwise open to working as a programmer for any researchers in the natural sciences who will take me.

Comment Re:Personally, I don't see a conflict (Score 1) 1774

The problem is that that approach only works if you take a very metaphorical interpretation of the bible.

With regards to evolution, if you accept it as true, then Adam and Eve in the Garden of Eden could not have happened. There were no "first humans," as there was no solid dividing line between our apelike ancestors and modern humans. If there was no Garden of Eden, then there was no original sin, which means that Jesus dying for our sins was pointless, unless God intentionally created as as inherently sinful creatures and then decided that we should be tortured eternally.

Well, to address at least that one point, one model I've heard from some Christian evolutionary biologists which seems to fit the data utilizes the Upper Paleolitic Revolution as a possible point in time at which humankind first became "spiritual" and therefore capable of sin. To quickly summarize the Upper Paleolithic Revolution (though I am not a bioligist/archaeologist/what-have-you; mere computer scientist and mathemetician by training), "anatomically modern humans" - ie, humans that look like you and me - have been found as far back as about 195 thousand years in the fossil record. But it wasn't until about 50 thousand years ago that we begin to see them exhibiting modern behavioral traits such as the creation of more advanced tools than they'd been using for 145 thousand years, accelerated language development, and the first evidence of religion. This sudden revolution occurred in East Africa or the Middle East and spread from there across the globe to anatomically human populations on other continents. It's been suggested by some Christian evolutionary biologists that this revolution represents the first moment in time in which God "breathed spirit" into humans, making them moral and creative beings, and from them it spread to others or their offspring. It could've begun with just two - who rebelled against God, making for original sin - and spread into the rest of the heretofore unspiritual, anatomical human population.

This solves at least two major issues. First, it allows for original sin. Second, it fits our genetic data which suggests that the genetic human population could never have been fewer than 10 thousand at any point in history; the unspritual population provides genetic diversity for the expansion of the spiritual population - or even become spriritual themselves through cultural interactions.

Comment Re:Fucking windows key (Score 1) 364

Seriously, you only found one shortcut for the Windows key? I find that surprising. There are quite a few more: Win+Arrow Keys can be used for window management (only in 7, to my knowledge), Win+R opens a run dialog, Win+D takes you to the desktop, Win+F opens a search window for the system, Win+E opens an Explorer window, Win+Break opens System Properties, Win+Spacebar peaks at the desktop (only in 7, to my knowledge), and Win+L locks the currently logged in account (useful if you live in a dorm or other environment where people like to mess with your system when you step away for a moment). There are many others, but these are the ones I find most useful. YMMV. I'm not sure what other simple key combinations could be used for the same functionality. And if you're using Mac OS or Linux with that Windows keyboard, it works as the command key or super key. So yeah, I'd say it can be quite useful.

Comment Starships (Score 1) 722

I name all of my computers after classes of starship from Star Trek. The netbook is called Nova (small, slow, but for short-term missions/computing only), the desktop-replacement laptop I just sold was called Prometheus (had a lot of power; that's about it), and the desktop I just built is the Dauntless (really crazy fast).

Of course, Nova only applies to the Linux partition on my netbook. Since its Windows install was originally a Chinese version which I converted over to English, some text still pops up in Chinese once in a long while (and usually just with error messages, almost like it's swearing at me in Chinese). I therefore break with tradition and call it Serenity when booted into Windows.

Comment Please Don't Mix Systems of Measurement (Score 0) 86

""With her most recent drive of 482 feet on June 1, 2011 (Sol 2614), NASA's Opportunity Mars Rover has zoomed past the unimaginable 30 kilometer mark in total odometry since safely landing on Mars nearly seven and one half years ago on Jan 24, 2004. That's 50 times beyond the roughly quarter-mile of roving distance initially foreseen"

Dear Universe Today source article,
For the future, can we NOT mix our systems of measurement, please? Seriously, I don't know if I should be thinking in feet, kilometers, miles, or cubits right now. Please please please just choose metric or, if you must, US units. But whichever you choose, stick with one or the other when discussing one topic. Don't switch back and forth. It makes it impossible to get a good mental picture of what you're talking about in terms of scale.
Sincerely,
Self-righteous Complainer (but you left me no choice)

Comment Re:Americans are Clever Enough to Know... (Score 1) 2288

.. that if they give 'em an inch, they'll take a kilometer.

And that would just confuse us Americans.

Fixed that for ya.

Actually, I live in the US and went to public school here, and they taught us both metric and imperial measurements from elementary through high school. I'm very comfortable using either, and usually think of distance in terms of meters and temperature in terms of Celsius. Admittedly, I'm in college studying CS (formerly with a focus in Electrical Engineering) at an engineering school so I probably have more exposure to metric than the average American. But if my public school education is at least any indication of my generation's comfort level with metric, it doesn't seem there would be too much backlash from the public if we were to switch to an entirely metric system within the next twenty or so years.

Of course, there's still the big issue of industries that are built around the imperial system, but if the people are at least comfortable with metric then that's one major hurdle that's already been overcome in my generation.

Comment Re:Wouldn't mining the moon be a bad idea? (Score 4, Funny) 421

This is a great discovery, but what are we going to do with it? The obvious thing is to mine it out, but wouldn't lightening the mass of the moon have a (probably quite bad) effect on it's tidal effects to the earth?

The mass of whatever rare elements we pull off the moon would probably be negligible compared to its overall mass. I would be more worried about the seemingly permanent change in appearance the moon would suffer with mining operations running on it. Without something like an atmosphere, any changes we make will be there for eons. I guess there's no practical reason for it, but I kind of like looking up into the sky and seeing a pristine lunar landscape. Maybe if they only mined the dark side of the moon....
