  1. Re:Rate of degrading? on Graphene Super Paper Is 10x Stronger Than Steel · · Score: 3, Informative

    My understanding is that pure carbon things sublimate into CO2 over time (including diamonds) when exposed to oxygen.

    I don't disagree that this might happen, but isn't this usually called oxidation and not sublimation? Sublimation refers to a state change (always C), and oxidation is a chemical reaction (C to CO2). If oxidation happens quickly enough, I heard it is called "burning"...

    (ducks)

    At any rate, you are partially correct in that diamond oxidation depends on sublimation occurring:

    The link has NO information.

    The PDF here: has more information about EDGE.

    The basic idea is that CISC/RISC architectures rely on storing intermediate data in registers (or in main memory on old skool CISC). EDGE bypasses registers: the output of one instruction is fed directly to the input of the next. No need to do register allocation while compiling. I'm still reading the PDF, this sounds like a really neat idea, though.

    The only question is, will this be so much better than existing ISA's to eventually replace them? -- even if only for specific applications like high-performance computing.

    I don't think this patents and copyrights are a big issue in this case.

    Many poor countries simply ignore patents and copyrights. Why? Their economies are usually heavy on agriculture, natural resources or low-tech manufacturing, and not so much in knowledge industries. There simply isn't enough supply to warrant having the laws, and in many countries the demand is low enough that it is simply not worthwhile for first world firms to push the issue too hard.

    There is one important caveat to this: sometimes demand for some patented product does skyrocket for whatever reason. One case in point is with AIDS drugs: there is an AIDS epidemic right now in Africa. Don't underestimate how bad it is: the word epidemic is so over used, I don't think it properly describes how widespread AIDS is in some countries. The first world manufacturers only wanted to sell at ridiculously high prices, considering how poor these countries are. Their insistance became moot when an Indian drug manufacturer agreed to sell AIDS drugs closer to the actual cost of manufacturing. The first world firms have since softened their position.

    The situation may change as poor countries develop, but then it will probably happen only because they will have a domestic industry to protect (think India in 20 years).

  8. Re:This is Microsoft Excel's fault on Climate Data Re-examined (updated) · · Score: 1, Redundant

    As I Canadian, I want to add a few comments.

    First, the National Post is noted for having a right-wing bias in its editorial section.

    Second, the piece in the National Post was written by an Earth Sciences professor of a University famously known as "last chance U": Carleton has one of the lowest admission standards in the province of Ontario, which tends to be correlated with the quality of faculty they tend to attract. They have a couple of good programs (such as journalism) but I can't say if the earth science department is very good or not, nor can I speak for the competence of the article's author.

    Third, as other posters have mentioned, the paper wasn't published by people who necessarily understand anything about climate - the work was done by an economist and an "independant consultant". I'm not saying that you need a PhD in earth sciences or meterology to contribute to the debate, but on the other hand, I'd like some reassurances they neither they nor the editors of the journal (how to put this?)... have pointy-hair.

    On the matter of the journal, I think it is a bit of a stretch to say they are "respected". As another poster mentioned, their website implies a slight bias to the warming naysayers crowd, and they are more or less touting this paper for publicity in a manner which verges on editorializing. Respectable journals don't do that.

    Finally, having read some things about the global warming debate, I think looking at historical warming data is interesting, but it might even turn out to be a sideline. What we know without a doubt is that CO_2 concentrations are rising exponentially, and that CO_2 is trapping solar energy. The question of the global warming debate (better expressed, perhaps, as the greenhouse gas debate) isn't "is it happening", but rather, "what will be the outcome", "how soon will we see the outcomes", and "what do we need to do to guard against the outcomes".

  9. Re:Can you imagine not needing software? on Is The Software Industry Dead? · · Score: 5, Insightful

    SO... I think there is a *massive* misunderstanding of what Ellison is trying to say.

    > If so, then can you imagine everyone not needing software?

    OK. Can you imagine everyone not needing salt and spices in their food? No? Now, make the leap - can you imagine the spice trade as a booming business minting new millionaries seemingly without end? Is that last statement too much?

    I hope so -- the spice trade is relatively unimportant in grand economic terms, but it was not this way in the 15th-17th centuries.

    Similarily, there will always be a software industry. But will it command the imagination of a nation? Or will people look to, say, nanotechnology or biotechnology for the next big boom?

    Also, I think Ellison stressed Silicon Valley as well.

    In the 1960's and 70's, led by Shockley, then Fairchild and then finally Intel, Silicon Valley was a thriving centre for chip making. Then chip making became commoditized and by the late 70's - early 80's, Silicon Valley was in a bust due to Japanese competition.

    But it bounced back.

    Then, in the 80's, defence R+D and PC software rose to promenance.

    Only to bust in the 90's.

    Finally, in the late 90's, there was the great internet boom... ...which is now an internet bust.

    So the real question isn't, "software, wherefore art thou?", but really, will the next economic revolution (and yes, the Internet revolution will go down in the history books as matching the industrial revolutions) again be due soley to software? Or will it be something else? And, will the next revolution be centered in Silicon Valley? Or will it be somewhere else?

    Don't think it must be in Silicon Valley - after all, the Internet revolution didn't happen in Manchester and Glasgow - don't expect the center of yesterday's revolution to be the center of tomorrow's.

  11. Re:higher fees will only make it worse on Patent Office Proposes Reform · · Score: 2

    Higher fees are not a solution. They just raise the stakes, so companies will try even harder to win patents.

    This may be the case if price of a patent application is the biggest cost the company has to pay. You could argue this is the situation software companies face, but how is this anything more than a minor annoyance to say, drug companies, who sometimes have to pay billions of dollars to get their (patented) drugs to market?

    Even if the cost of getting a patent examined is the biggest, another poster (Planesdragon) notes how your logic is flawed - you're confusing payoff (revenue) with price (costs).

    These "reforms" will serve only to line the bureaucrats' pockets with the blood of the independent inventor.

    This might be a valid point - it depends how big the fees are. Looking at the article, they mention $1250. Using words like blood for what seems like a modest amount of money does seem a bit harsh.

    This may come out against independent inventors, as you suggest, but I think the idea of one inventor working alone is a bit of a myth. At some point in time, if the idea is really good, you'd need to start a company to market it. And if you can't raise $1250 for a patent application, you wouldn't be able to pay two employees for a week.
