called HECS.

It began in the 1990's and was developed by the economist Bruce Chapman.

It is a great success in Australia. I graduated under the system. It was perfect for me, because I had no money to study but made some after and payed the loans through my taxes.

I work in an area where most of the top journals are owned by Elsevier. Also most of my publications are with Elsevier and I'm on several editorial boards for Elsevier journals.. I've been thinking of resigning from editorial boards on Elsevier journals and starting new arxiv based journals because of the cost of journals. This breaks the camel's back. Elsevier can bite me.

shares in a remittance company that is likely to take Western Union to Blockbuster territory. But valuing these assumes you are buying shares that will eventually pay dividends, and when not paying dividends will appreciate because profit was is reinvested.

But Bitcoins are not shares. When you buy a Bitcoin you are not buying equity in the Bitcoin environment. Wonder what model BoA valuers have in mind for this. It weirds me out.

RMS, I watched the interview on youtube, and I don't think that he understood the anonymity issues of Bitcoin. He's not on top of the issues or the technology.

He has in mind markets with one-sided-anonymity in which the seller is known (a big cooperation) to the buyer while the buyer is anonymous to the seller. Basically he's thinking about online shopping with Walmart on one side and an anonymous buyer on the buyers side. Bitcoin provides anonymity in both directions seller-buyer, which he did not seem to appreciate. Bitcoin allows for anonymous markets and not simply anonymous buying. Bitcoin has the potential to change how we conduct commerce and not simply to facilitate privacy in exiting market structures.

Also, I simply could not understand his statement that "we have had the anonymity technology (his kind of anonymity) for decades". I really don't think that he was thinking of zerocoin.

and "complete" solutions have been around for more than a decade.

The question that may be interesting, is why have people not adopted niche complete hosting providers. I don't know, but to tell the truth I need to wake up each morning knowing that my information is reliably accessible _me_, my credit card numbers haven't been sold, and that if my provider goes down I can read about it in the NYTIMES, that's all slightly more important to me than my worry that the US/German/French governments can read my crap.

When did China become an enemy of the US? As far as I know it's a competitor, it is a steadily growing economic giant. Yes, but hardly an enemy. Unless, of course, we're back to 1972 when everyone not in the English speaking world that is not a CIA run dictator is an enemy. Frankly, the US is too small and becoming too irrelevant to safely classify the large chunk of humanity called China as an enemy.

western expats or the Saudi nationals. They are worried about the millions of Asian workers, maids, drivers, cleaners who are treated like slaves. You don't have effective control over slaves if you let them communicate with their family whenever they want. Saudi Arabia is a hell hole for millions of people who have sold themselves into effective slavery, and the US government treats the place like its main ally in the region. Something about American history tells me it's a natural alliance.

The notion that consumers will one day be able to customise 3D designs on their computer screen and print them at home is fanciful. Anyone who has tried to teach/learn three dimensional geometry can tell you that 3D hurts the brain. We don't even see in 3D. The retina is 2D and we have some vague conception of 3D. Close your eyes and consider for example the intersection of two ice cream cones. What does this look like? Is it ever an ice cream cone? Going beyond this, there are geometric phenomena in 3D that have no analog in 2D, which we don't naturally perceive, The problem is that we design in 2D, our mind's eye is 2D, our experiential perspective is 2D, and our design technology is 2D. Our perception of 3D are essentially some sort of projections of 3D Objects. It took painters centuries to even conceive of this. (Of course, you can train your 2D mind to design 3D objects , but basically you've got to be a specialist. For these designers, why would they choose 3D printing, it looks like a lathe tool to me but you are restricted to the material you can use. )
