I've seen a lot of academic resistance to the Kahn Academy. I want to take a brief moment to respond to a large portion of it. I'm sure that those making such studied arguments are familiar with the second chapter of "To Kill A Mocking Bird." The critiques coming from this corner of academia sound just like Miss Caroline denouncing Scout because she has learned to read in an "unapproved" way.
IMO this video might be fine as a supplement for a student who has poor problem-solving skills and needs to see some very explicit step-by-step remedial instruction in how to solve a plug-in problem, but it would be disastrous for a student to get her first introduction to gravity from this lecture. The lecture just presents a formula and plugs in numbers. There is almost no intellectual content there, just some calculations being cranked out using a formula that pops up mysteriously out of nowhere.
Have you been to a high school physics class recently? This is exactly how high school student are taught physics. At least here it is done without an additional 20 minutes of "classroom management" getting in th way.
This is the third time I read a link to this article and there are far too many college prof's who think that there is some magical great education going on in k-12. If your objection to the Khan academy is that is is substandard learning, please know that it is far better then what actually happens in a lot of real classrooms.
Neither the US nor any other country should phase out nuclear power until there is a firm policy on how to deal with the nuclear waist.
When the US started the first large scale use of nuclear fission, it created an obligation to either store or otherwise render safe the resulting spent fuel. At the time it was believed that technological advances would eventually render the fuel safe. In the ensuing 50 years this has been shown not to be the case. One then might ask why we should continue to produce this spent fuel given that we have no way to deal with it.
The reason is that the spent fuel problem does not scale with the amount. The danger of storing 25 dry casks and 500 is approximately the same. For example it is not more difficult to keep a potential terrorist away form a sight with 500 dry casks then it is for a single cask. The issue then becomes keeping constant watch over this spent fuel. So long as a plant continues to operate, its operators will have financial incentive to maintain its spent fuel storage facilities. Once a plant is shut down it reverts to the public or becomes a mandate to a company who no longer has any interest in doing more then appeasing a regulatory body.
In addition, an operating plant has use and value, but once it is closed, a large portion reverts to nuclear waist. It is in everyones best interest to operate plants as long as can be done safely so as to maximize the value of to society of the waist they will inevitably produce. Closing a plant with 20 years of life does not reduce the amount of clean-up required to close the site.
The reality of the situation is that for the foreseeable future the only two options for current nuclear sites is to continue to operate a nuclear facility in the safest manner possible or turn the site into heavily secured nuclear dump.
Some final perspective, if Romulus and Remus had build a nuclear plant at the founding of Rome in 753 BC and somehow kept managed to keep the waist safe from war, natural disaster, and neglect to the present day, we would still be less then half way to "safe levels" of decay.
If you didn't want universities to become trade schools, why did you academics spend the last 60 years trying to devalue a trade school degree. Please don't act so shocked that there are people trying to learn a professional skill in your Ivory Towers when it was those Ivroy Towers that propagated the myth that only there degrees would do for a professional.
I don't think either of those would be a good place to cut, but I'd agree to it in order to get a similar sized cut was made to the Department of Corrections.
Very similar concerns were voiced by first the Railroad then the Trucking industry before Time On Duty limits were implemented. Given proper rules and enforcements, hospitals and surgical teams will adapt there lives to fit. In the Parent example, Seven person groups would keep On-Call and O.R. schedules in sync and non-conflicting.
Why teach the applications practical to 95% of white collar jobs instead of programming, which most kids won't be interested in, fewer will 'get' and hardly any will ever do professionally?
Because by the time students reach Jr. High where a dedicated course in computers can be taught, the ones who are interested in such a course already know spreadsheets, word processors and PowerPoint -- often in more depth then the teacher. The correct solution seems to be to teach a business applications course to those who need it and still offer a Computer science class for those who have enough brains to learn business applications on their own.
What you say about unlawful enemy combatants is true assuming the following: * you are not a US citizen * you were captured outside the US * you are not a member of any nations uniformed military services (you would then become a POW instead) * you were not arrested by civilian law enforcement (including the FBI, ICE, or Border Patrol) * no charges were presented against you in a civilian court
And sense the election of Pres. Obama: * there is no country to which you can be safely repatriated
NY to LA would be nice but not the intent of high speed rail; SF to LA is. Or maybe NY to DC.
For both of these flights, passengers spend more time moving through airport security theater and check-in/baggage claim then they do in the air. HSR will go city center to city center with faster door-to-door times cheaper costs, more leg room, and most importantly add 25% more capacity to LAX and SFO for NY to LA and NY to HK.
Please remember that high speed rail is competing with commuter air services not morning commuters. How far is it from your work to the nearest commercially served air port?
News publication should remain a for prophet business. Only the gathering editing of news is a public service. Particularly, local news gathering should be able to be done by not-for-profit corporations.
If what you suggest were actually done, you might have a point, but all the EMR software I've seen has a nightmare interface, numerous features disabled (and done on paper instead) because they don't comply with the law, and a security model that is modeled after having physical access to a terminal because that is how the paper charts are secured!
Honestly the current software out there makes Diebold look like a secure and competent vendor.
Keep your code and use Rack to factor out the last 5%. You can keep you code base, and still get your performance. Merb is a an excellent tool for this. It is similar enough to rails to be easy to pick up, but it is light weight and has the ability to run a small application in a single file.
Without knowing how tightly coupled that 5% is it is hard to be more specific, but definatly look into Rack.
This means no loops! Most algorithms that are stated in imperative form take a non-trivial amount of effort to restate in functional form. The only saving grace is that the opposite is true as well, and a lot of things are hard in imperative languages become ridiculously easy in functional ones. The bad news: q-sorts and Fibonacci become easy while User Interface gets a lot harder.
...but "Family Physicians" are paid far, far below the rate of the rest of the medical world. Could you include -for example- Emergency Medical Doctor which is where 32.7% of folks in my state get primary care?

Ok, I'm impressed - where do you keep your infinitely large memory tape?

Let's rephrase the question then: Can we expect to observe Betelgeuse going supernove in our lifetimes?

No, I don't, but it is against the la for a Taxi Driver to drive drunk. OTOH there is nothing legally preventing a doctor from Operating without sleep

There are some number of modern works that are for some reason cataloged at the turn of the last century. Try Internet for similar results.

The HVAC system is required by building codes otherwise some companies would not provide it. Scary I know.
