I have not looked at the patent application, but based on the description, it appears to me that Apple is trying to patent something similar to what WiTricity is doing, rather than what Tesla has demonstrated. From the WiTricity wiki:

Unlike the far field wireless power transmission systems based on traveling electro-magnetic waves, WiTricity employs near field resonant inductive coupling through magnetic fields similar to those found in transformers except that the primary coil and secondary winding are physically separated, and tuned to resonate to increase their magnetic coupling. These tuned magnetic fields generated by the primary coil can be arranged to interact vigorously with matched secondary windings in distant equipment but far more weakly with any surrounding objects or materials such as radio signals or biological tissue.

Ok. I am not going to start refuting the details as this is not the forum for that. Let me just summarize what you are saying: Austrian economics predicts that inflation will rise eventually.
You see, this is not a testable prediction. It can be said for _anything_ that will happen eventually and that would be almost certainly correct. The question is what would happen now and in the next few years at most.

In the case of inflation Austrians started predicting that inflation would rise substantially about 2 years ago and many people made big noises about it 1 year ago saying that it would happen imminently. Result? The inflation is now _lower_ than it was back then.
This is sufficiently long time to test the validity of the predictions. Again, only the liquidity trap theory predicted _exactly_ that. The current budget impasse will likely muddle the waters and the effects are hard to predict in detail, but the situation will probably not change significantly soon in terms of inflation.

Ah. You study at the University of Chicago or something, I guess? Such opinion is extreme ideology and is hard to take seriously. For example:

> Government spending does not "stimulate" the economy.
I see. I suppose that is why the major banks downgrade their GDP estimates as a result of the prospects of decreased government spending? And why the UK economy nose dived as a result of the austerity package?

> The value of a theory is measured by its ability to predict... yet Keynesians have never predicted any major economic events... even though Monetarist and Austrian economists have.

Heh.
Monetarism quite correctly predicted the stagflation. It is failing miserably in the current situation of liquidity trap, however. It predicted that Japan will recover 10 years ago after increasing the money supply, for example. Nothing happened. The effects of QE2 were far smaller than predicted, etc.
Austrians: Even Milton Friedman did not think that theory had much to do with reality.

Also, all of those theories were predicting massive increase in inflation and/or long term interest rates due to the economic policy in the past two years. What happened? The interest rates are at historic lows instead. That's a massive failure of the predictions.
Only the liquidity trap theory predicted what happens accurately. And it is a consequence of the Keynesian theory.

The way to fix the economy in a normal, non-liquidity trap situation (i.e. almost always) is through monetary policy exclusively, no question about that.
Monetary policy does _not_ work well at this very moment, however. A fiscal stimulation is needed to get the economy out of the swamp and get the interest rates above 0%. After that we can revert to monetary policy again.

During 2001 the IPCC made a number of predictions as to what would happen as a result of the climate change. At the time their results were widely mocked and ignored by the "climate change deniers" circles.

It now turns out that the actual effects measured today are _worse_ than what was predicted. For example, the rise of the ocean level is 80% greater.

I think people should concentrate on the larger picture -- the predicted effects are happening. The whole CRU emails issue is peanuts and only diverts the attention from the real issue, even if we assume that everything that is being claimed there is true.

Comment: vCloud API Standard -- ability to move elsewhere (Score 1) 250

by Mindbridge (#29654427) Attached to: Is Cloud Computing the Hotel California of Tech?

The vCloud API (http://www.vmware.com/solutions/cloud-computing/vcloud-api.html) is a protocol for placing VMs into a cloud, managing them, and downloading them back when needed. It was published at the last VMworld using a very liberal license and has been submitted to DMTF for standardization. While it has been initiated by VMware, the vCloud API has been designed to be implementation-agnostic and could be implemented over Xen or other hypervisors.

The whole idea is for people to be able to download the data/VMs that they have in one cloud and move it easily to another if they desire to do so. In short, this is the opposite of Hotel California.

Heh. I have awards from both IOI and ACM (gold medals, etc) and have significant industry experience, so I feel that I know what I am talking about :)

Most programmers apparently believe that the best way to make a scalable application is to (re)write it in assembler. The responses to my post seem to prove that point. Perhaps architecture/design competition is more necessary than I thought.

Comment: Testing architecture and design (Score 2, Insightful) 74

Software Development consists of several relatively independent skills:
    - programming (knowing how to use the tools)
    - algorithms
    - architecture and design
    - knowledge of processes (development methodologies, etc)
    - enabling teamwork (allowing many developers to work together)
etc.

The IOI competition is for high-school students and tests mainly the 'algorithms' aspect.
The ACM competition is for college students and tests mainly the programming aspect. (strange, one would think that the aims of those two would be reversed)

There does not seem to be a big competition for testing the architecture and design abilities, although arguably they are even more important (unless you count the Real World competition). Part of the difficulty perhaps is that it is tricky to come up with an objective measurement. An approach that I have been using is the following:
- give a task and provide plenty of time
- at 50% of the time change the requirements of the task slightly
- at 90% of the time change the requirements significantly
If proper design has been used, then making appropriate modifications would be easy and the task would be accomplished in time. This closely mirrors the situations in reality.

FOSS Development As Economic Stimulus 365

Posted by kdawson
from the piece-of-the-action dept.
heybus writes "Economist Dean Baker, best known for calling the housing bust and warning of the ensuing economic collapse, has just published his recommendations for how to allocate President-elect Obama's estimated $800 billion economic stimulus plan. Among other things, Baker calls for juicing the economy with $2 billion worth of government spending to support the development of free and open source software. Baker's idea is similar to the New Deal federal arts and writers' projects: the government would fund projects as long as they produce freely available code. In addition to employing programmers, 'the savings [to consumers] in the United States alone could easily exceed the cost of supporting software development.'"

If it survives its first test flight, the Terrafugia Transition, which can transform itself from a two-seater road car to a plane in 15 seconds, is expected to land in showrooms in about 18 months' time. Terrafugia claims it will be able to fly up to 500 miles on a single tank of unleaded petrol at a cruising speed of 115mph. Even at $200,000 per automobile, they have already received 40 orders."

ReadWriteWeb writes "Climate Counts, which launched on June 19th, is a non-profit website that rates corporations based on their environmental impact. They use a 22-item scorecard that asks questions like "Is there top-level support for climate change action?" and "Does the company require suppliers to take climate change action or give preference to those that do?"

It would seem that web companies (at least large corporations involved in the web) mostly have a long way to go toward helping clean up the environment. Only News Corp., Yahoo! and Microsoft on this list scored favorable ratings. Google scored a rating of "Starting," meaning that they are heading in the right direction but have a long way to go. Also scoring poorly was Apple, which has come under fire for their environmental track record before. This is disappointing, especially given that former US Vice President Al Gore, one of the world's most prominent environmental activists, sits on Apple's Board of Directors."
