Physicists detect elusive orbiton by 'splitting' electron->

Submitted by ananyo
ananyo writes "Condensed-matter physicists have managed to detect the third constituent of an electron — its 'orbiton'.
Isolated electrons cannot be split into smaller components, earning them the designation of a fundamental particle. But in the 1980s, physicists predicted that electrons in a one-dimensional chain of atoms could be split into three quasiparticles: a ‘holon’ carrying the electron’s charge, a ‘spinon’ carrying its spin and an ‘orbiton’ carrying its orbital location.
In 1996, physicists split an electron into a holon and spinon. Now, van den Brink and his colleagues have broken an electron into an orbiton and a spinon (abstract).
Orbitons could also aid the quest to build a quantum computer — one stumbling block has been that quantum effects are typically destroyed before calculations can be performed. But as orbital transitions are extremely fast, encoding information in orbitons could be one way to overcome that hurdle."

Twitter plans to give control of their patents to their engineers->

Submitted by Acapulco
Acapulco writes ""With the IPA (Innovator's Patent Agreement) employees can be assured that their patents will only be used as a shield rather than as a weapon." Said Twitter's Engineering VP.

In the blog he also said "Like many companies, we apply for patents on a bunch of these inventions. However, we also think a lot about how those patents may be used in the future; we sometimes worry that they may be used to impede the innovation of others. For that reason, we are publishing a draft of the Innovator’s Patent Agreement, which we informally call the “IPA”."

The BBC has other details on the story."

Point well taken. But how about (and I have absolutely no idea if these companies you mentioned tried anything liked thir or not), releasing "version lines", so you actively maintain and fix bugs for v1 line, and sell v2. Or maybe as another poster said, which I know would amount to crippleware to some extent, but that's another discussion, have some "freemium" approach in that v1 is the same as v2 bugs-wise, but not feature-wise. So you backport to v1 all the bug fixes you...uhmm..fix.. in v2, except of course those which have something to do with an unsupported feature.

Of course this means solving a host of other problems, considering you have to keep two similar-yet-different codebases, still, I'm interested in what you think of this. Maybe as you say, him alone could not handle it, but may be a small team could?

I mean, there *must* be some way of satisfying both needs of what I would say is a big group of developers, wanting to contribute their grain of salt but not completely ready to embrace full-blown oper-source models. Or are we coming to a point where you basically have no real choice (regarding successful penetration in the market) between going RH style open source or traditional closed source? is there really no other viable way of doing this? (and I ask sincerely, no sacarsm intended)

I believe parent has nailed it.

Ethically you want to do what is closest to your heart if you will, but unfortunately you need to eat, and usually this involves doing the opposite of ethical (or at least far from what the ideal-ethics tell you)

So I propose this. How about you release version 1.0 and 1.5 for example (or 1.0 and 2.0 or something) as regular closed-source software, and then when the next version comes out, you release the previous one as open source (e.g. release 1.0 and 2.0 for pay, when you release 3.0 for licensing you release at the same time v1.0 as open source)

Of course this would mean that you would have to have a road map for what you plan to introduce to your software along the years, so its easier to establish which version is to be safely released as open source without it hurting your paying customers. So, I think you would have to make significant changes and upgrades along the life of your software so it stays competitive and entices costumers to keep upgrading instead of waiting for the open source version, or in the case where the user doesn't really need the "greatest and latest" he could fallback to v1.0.

Disclaimer: I haven't actually put to work something like this, and actually this is an idea I believe I read here on Slashdot as it is, but I think, if not directly useful to you, could give you an idea of a "hybrid" approach, where certain functionality is still closed source as it requires the most of your time (so it costs more) but you still have the open version to maybe encourage some devs to take interest in this framework, or at least show your clientele that you really care about open source however economically infeasible it is for you.

I would say its on the same line of thought as "pay-what-you-think-its-worth" for games like World of Goo and such. You could effectively buy it for 1 dollar, but like me, a lot of people thought it was really nice of them to do this and since I actually enjoyed the game a lot, I payed like 15 or 20 USD (the original price). And even use that as a marketing tool.

Just my 2 bytes...I mean cents.

Is it just me or does anyone else think congress people spend way too much tax-payers money coming up with these bill names.

I mean, come on: PROTECT IP, PRECISE, etc etc. It almost seems as if they would get together to discuss the naming instead of the actual bill content.

No?

Beyond the obvious fact that we will never know for sure who actually created it, it seems pretty naive to think a US 'cyber analyst' would say or even think anything different. After all Israel is a close US ally so it isn't like they would be interested in "telling the truth". It's like the boy who punches the other boy behind the teacher's back, of course he is not going to rat itself.

So how is this a credible source? Maybe if it came from a team of international security researchers with evidence or something I would deem it a valuable piece of analysis.

I kinda see this "research" as the ones conducted by Microsoft to evaluate IE, or Google to do so with Chrome and, oh surprise, they always come ahead. More like a political thing to say than any actual useful information or analysis being brought to light.

Building Robot Sailboats to Suck Up Oil Spills->

Submitted by
CoveredTrax
CoveredTrax writes "After visiting the BP oil spill in the Gulf of Mexico, in June of 2010, the young engineer, Cesar Harada decided to leave MIT in Boston to develop the open source oil spill cleaning robot, Protei. Our current array of oil spill skimming technologies — mostly private boats retrofitted with skimming equipment and skimmers maintained by the U.S. Coast Guard — are only able to collect 3 percent of the oil in the Gulf of Mexico and carry health risks to humans and heavy economic costs. Protei is unmanned, autonomous, relatively inexpensive and open hardware (anybody can use, modify and distribute its designs), making it a potentially powerful weapon in the battle to clean up the Gulf, while preserving the safety of the workers who would otherwise be exposed to the toxic mess. Already Harada imagines other uses for the sailboat drone, like oceanography and surveillance."
