Submission + - MIT team invents efficient shockwave-based process for desalination of water. (

An anonymous reader writes: As the availability of clean, potable water becomes an increasingly urgent issue in many parts of the world, researchers are searching for new ways to treat salty, brackish or contaminated water to make it usable. Now a team at MIT has come up with an innovative approach that, unlike most traditional desalination systems, does not separate ions or water molecules with filters, which can become clogged, or boiling, which consumes great amounts of energy.

Instead, the system uses an electrically driven shockwave within a stream of flowing water, which pushes salty water to one side of the flow and fresh water to the other, allowing easy separation of the two streams.

According to the researchers, this approach is a fundamentally new and different separation system. Unlike most other approaches to desalination or water purification, this one performs a “membraneless separation” of ions and particles.

Membranes in traditional desalination systems, such as those that use reverse osmosis or electrodialysis, are “selective barriers”.

They allow molecules of water to pass through, but block the larger sodium and chlorine atoms of salt. Compared to conventional electrodialysis, “This process looks similar, but it’s fundamentally different,”

In the new process, called shock electrodialysis, water flows through a porous material —in this case, made of tiny glass particles, called a frit — with membranes or electrodes sandwiching the porous material on each side. When an electric current flows through the system, the salty water divides into regions where the salt concentration is either depleted or enriched. When that current is increased to a certain point, it generates a shockwave between these two zones, sharply dividing the streams and allowing the fresh and salty regions to be separated by a simple physical barrier at the center of the flow.

Submission + - Nokia Deal Proves Steve Perlman's pCell "Isn't Another Cold Fusion" (

Tekla Perry writes: Nokia Networks has agreed to deploy Artemis' pCell technology in its equipment, and a tier-one communications company will start real-world testing in early 2016. Widespread national deployment in the United States could happen in as soon as a year, Perlman said. “Doing a deployment in a city could take just a few months,” he said, “because we don’t need to be on towers, our antennas can be on rooftops or in windows. They don’t need to be aimed, because they are just tossing around interference.” The technology, which embraces rather than avoids interference and increases capacity of a network by a factor of 50, preventing the dramatic drop in cellular data rates typically experienced by users in crowded environments, has faced much skepticism since its unveiling nearly two years ago.

Submission + - Don't Let Final Fantasy V Happen to You - Do HD Remakes the Right Way (

lars_doucet writes: Final Fantasy V just came out on Steam — a beloved classic game — only to showcase an art-style that fans and developers alike are criticizing for being rushed and sloppy.

It's not just a matter of questionable taste — the new game engine is a veritable laundry list of glaring technical flaws such as an awkward base resolution, tiling artifacts, and grossly mismatched art styles.

In response, game developer Lars Doucet lays out a lengthy and detailed list of best (and worst!) practices for "HD remakes":

Submission + - Open Hardware Team successfully replicating Tesla inventions (

lkcl writes: A small team has successfully overcome the usual barrier to replicating one of Tesla's inventions (death threats and intimidation) by following Open Hardware development practices, encouraging other teams world-wide to replicate their work. Their FAQ and several other reports help explain that the key is Schumann resonance: "tuning" the device to the earth's own EM field and harvesting it as useful electricity. Whilst it looks like it's going mainstream, the real question is: why has it taken this long, and why has an Open Hardware approach succeeded where other efforts have not?

Submission + - Ask Slashdot: Personal source control options?

McLae writes: I am looking for personal source control options. Here are the constraints:

Must run on Windows PC. Not server, just regular PC. Win 7 or win 8+.

Low cost or free. ( less than $100) (Rules out VSS)

Easy to install. No need to configure ports or firewall settings.

Self contained. No server or network access required.

Must include database. (Like Darby?) No separate database install.

I had an application like this 20 years ago that ran on DOS. What are the current options?

Submission + - There Is No Honeybee Crisis ( 1

iONiUM writes: An article today claims that there is no longer any Honeybee crises, and that the deaths of the Honeybees previously was a one-off, or possibly non-cyclical occurance (caused by neonics or nature — the debate is still out). The data used is that from Stats Canada which claims "the number of honeybee colonies is at a record high [in Canada]." Globally, the UN’s Food and Agricultural Organization says that "worldwide bee populations have rebounded to a record high." However, many corporations and pro-environment groups have much to gain by creating a panic about Honeybee deaths, and as such continue to publish stories claiming the situation is dire.

Only the 2nd should be illegal. There is an increasing trend (decades I mean, if not longer) to criminalize what "might" occur, rather than just criminalizing actual harm. Here's a summary of what I "think" should be the laws: Shooting somebody - illegal Just carrying a gun, openly or not - not illegal. Recklessly shooting into the woods - maybe The last one's the hard part, but it slips so easily into "pre-crime" that it gets weird, and makes people afraid to do anything that "might" end up being a crime, though nobody was hurt. Thus this issue: Putting a gun on a drone - legal Shooting somebody with a gun on a drone - DEFINITELY ILLEGAL All IMO.

Submission + - Meet MUMPS, the Programming Language for Healthcare (

citadrianne writes: An ICU patient is monitored and assessed according to 12 different variables. These include such measurements as body temperature, heart rate, blood oxygenation, blood pH, and others. Together, they're used to formulate a quantitative answer to the question, "How bad is it, doc?" Many of these physiological signs are measured in real-time via electrodes and like a billion different varieties of catheter. Add to it barrages of lab tests done multiple times per day per patient and the need for 20 or so clinicians (per patient) to have access to all of this data, and the result is very a deep data problem.

Multiply that data problem by hundreds of thousands of patients.

This is the fundamental problem that the programming language MUMPS (sometimes called just "M"), or the Massachusetts General Hospital Utility Multi-Programming System, aims to solve. To its proponents, MUMPS allows for a one of a kind synthesis of programming and database management, while to to its detractors, it's a bizarre anachronism with little connection to the evolution and innovation taking place elsewhere in programming. Probably to most people that do things with computers, MUMPS/M is poorly understood, at best, and more likely to be completely unknown.

Submission + - Faith-Based Intellectual Property

An anonymous reader writes: A new article by Mark Lemley (a law professor at Stanford) makes the case that today's intellectual property law is based on quasi-religious beliefs rather than factual data. From the abstract: "The traditional justification for intellectual property (IP) rights has been utilitarian. We grant exclusive rights because we think the world will be a better place as a result. But what evidence we have doesn’t justify IP rights. Rather than following the evidence and questioning strong IP rights, more and more scholars have begun to retreat from evidence toward what I call faith-based IP, justifying IP as a moral end in itself rather than on the basis of how it affects the world. I argue that these moral claims are ultimately unpersuasive and a step backward in a rational society." It's a very interesting read free from legal jargon, but citing a lot of studies about what is actually known of the effects of intellectual property laws on creative production.

Submission + - Seed from ancient extinct plant planted and brought back to life

schwit1 writes: Israeli scientists have successfully gotten a 2000-year-old seed of an extinct date plant to grow and now reproduce.

Methuselah sprouted back in 2005, when agriculture expert Solowey germinated his antique seed. It had been pulled from the remains of Masada, an ancient fortification perched on a rock plateau in southern Israel, and at the time, no one could be sure that the plant would thrive. But he has, and his recent reproductive feat helps prove just how well he’s doing.

For a while, the Judean date palm was the sole representative of his kind: Methuselah’s variety was reportedly wiped out around 500 A.D. But Solowey has continued to grow date palms from ancient seeds discovered in the region, and she tells National Geographic that she is “trying to figure out how to plant an ancient date grove.” Doing so would allow researchers to better understand exactly what earlier peoples of the region were eating and how it tasted.

I agree, find SOME way to get that onto a local network, and that will be BY FAR the easiest way to do things. Maybe dig up an old ISA 10Mbps card on Ebay or something, as the original poster suggested if you can't find a suitable PCMCIA card.

And combining with something said above, it's not difficult to find a usb->serial port device/cable (it's not just pin-out, so it's a device, not merely a cable). Pretty cheap. Same with a null-modem cable. Both together should run you in the range of $20-$40 or less. Then hook it directly up to whatever computer you want that has a USB cable, and get a terminal emulator (plenty available) and transfer.

It CAN be done, but I'm with the parent that windows file sharing via ethernet is going to be the fastest by far.
