It's a great point: people who don't have an emotional investment in the Department of X can easily see that the people who make up the Department only care only for improving their own power and financial position, and are making X even worse both by getting in the way and also by consuming valuable resources that could be used to actually provide X instead.

The difficult part is realizing this is true for all X, even the ones which are your personal favorites.

Ripple is a debt accounting system.

You can send Dollars or gold over Ripple - you can transfer promissory nodes for those things.

The difference between a promissory note and the value the note represents is something that Ripple should be trying to clarify - instead they seek to obscure it.

Because they try to pretend that promissory notes are equal to underlying assets, they don't include any features that would act like leverage limits. There is no ability to deal with counterparty risk rationally in their system, since trust in a counterpary is binary.

In real world, liabilities of different entities are discounted by a value that reflects their credit risk. Ripple does not permit this operation. You either value liabilities at par or not at all.

As others have mentioned, their consensus system is neither distributed nor trustless. It's a centralized, badly-designed, debt accounting system trying to pretend it's a trustless cryptocurrency.

Actually, it's going to work just as well with real world services and goods.

they can simply catch you at the payment


or make a take down on your server on non compliance

You do know there is an entire planet where servers can be hosted, right?

Also, have you ever heard of "peer to peer networks"? I hear they are making waves these days.

And frankly as a customer there ARE some law i want respected, no matter what you young guys think of them

That's wonderful. You will always be perfectly free to choose taxi server providers which meet the standards you want.

As long as you don't try to interfere with the choices of other customers then there is no problem.

Whatever you call the generation of people between 25 and 35 learned the Napster vs Bittorrent lesson very well.

Uber and Lyft may die, but they'll just be replaced with entirely P2P systems.

Sting operations give us both an incentive and the opportunity to develop trust network that optimize for protecting sellers from malicious customers. Once developer, the applications for such trust networks will be quite broad.

The era in which one group of people will be able to control the commercial activities of third parties is coming to a close. Deal with it.

And you really really needs carbs to live. What is your point?

You need carbs to live, but it's fine for as little as 0% of those carbs to come from your diet. Your body can manufacture all the glucose it needs given the right protein and fat supplies.

+ - fMRI Data Reveals the Number of Parallel Processes Running in the Brain->

Submitted by xgeorgio
xgeorgio (1179155) writes "From MIT Technology Review — Emerging Technology From the arXiv (5-Nov-2014):

The human brain carries out many tasks at the same time, but how many? Now fMRI data has revealed just how parallel gray matter is...
...The results make for interesting reading. Although the analysis is complex, the outcome is simple to state. Georgiou says that independent component analysis reveals that about 50 independent processes are at work in human brains performing the complex visuo-motor tasks of indicating the presence of green and red boxes. However, the brain uses fewer processes when carrying out simple tasks, like visual recognition.
That’s a fascinating result that has important implications for the way computer scientists should design chips intended to mimic human performance. It implies that parallelism in the brain does not occur on the level of individual neurons but on a much higher structural and functional level, and that there are about 50 of these.
“This means that, in theory, an artificial equivalent of a brain-like cognitive structure may not require a massively parallel architecture at the level of single neurons, but rather a properly designed set of limited processes that run in parallel on a much lower scale,” he concludes..."
