I'll do my best to sum up what I do. I've never put this in words before.

My modus operandi involves building a mental model of what the student knows, doesn't know, and how they think about the problem in question. Usually I do this through targeted questioning, and watching faces for signs of confusion in a group session. e.g. let's say we're working on Newtonian physics. I might take a model car with occupants, roll it along a table, and ask what happens when the car hits something. From this I can judge whether the students understand momentum.

If their mental model is wrong, next you have to break it down. How to do this varies based on how committed they are to their model -- if you challenge their views in too dramatic a manner you can lose their trust and frustrate future lessons. For students whom are less committed to their incorrect model, it suffices to demonstrate a counterexample. Those who are more commited can require several weeks to shake their beliefs.

Actually teaching involves three parts: definitions, questioning, and experience. Definitions are KEY. You can build an entire lesson around a solid definition. For example: "speed is how far something travels every second" (or "in a certain amount of time" for the ones able to handle abstraction). Keep definitions few and far betweens and simple. Refer back to them often.

Next follow up with questioning: how can we measure speed? do we know how to measure the things in the definition? if something moved ten meters in five seconds, how many meters did it move every second? This has been covered elsewhere in depth. Don't overdo it though, some kids hate questioning. Just tell them facts.

Oh, be consistent. Use vocabulary consistently, don't throw around new terms, stick to one system of units, etc. Minimize distraction and confusion.

Experience is key to solidifying rules deduced from questioning. Roll that cart down the hill. Practice those factoring problems. Not everyone needs experience but most do. Experience can help break down incorrect mental models. As with definitions, minimize distraction. Experience one thing at a time until it is understood.

Finally, don't be afraid to go off on tangents. If a kid expresses interest in something, that means they will be focused and eager to learn it. You can teach almost anything to a student who wants to learn it. Motivation is everything.

I hope this helps. It's early in the morning and I'm writing this on my Kindle so it's probably rambly and missing things. I'll try to remedy that throughout the day.
When you think of the phenomenal potential of the human mind to feel, explore and create (at whatever level the individual is capable of) the idea that most of us should spend most of our time doing things we dislike is pretty ridiculous.

My least favourite modern concept is the idea that everyone must have a job, and that the most mind-numbing job is better than any alternative.

The most dull and incapable human is still able to feel joy, wonder and excitement as powerfully as anyone else. Not all of us could spend our technologically-driven retirement writing like Shakespeare, painting like Monet and exploring like Richard Branson, but our average quality of life has a very long way to go.

There's some residual puritanical disgust at the idea of living mostly without work, but it's clearly going to become technologically possible in some number of years. This post-scarcity world is when we're going to really be able to shine as a species, even if our society will be radically restructured in the process. Radical restructuring can be a positive thing - think of how much the life of a woman has changed in the past 100 years.
The idea had apparently been around for a while, since 2008 or so, there were other, similar studies. I don't know if they were similarly flawed or not though.

I also would not completely dismiss the premise - trees are probably very good at converting solar energy.

And to add to that, I don't buy the counter argument that a tree arrangement can't be better than a flat panel - why not? The sun moves around so the flat panel might be optimal at one point in the day, but will certainly be sub-optimal at other times. This isn't a clear cut argument at all. There are many variables in play. Cloud cover; seasons; etc. Keep in mind the experiment was done in a cold climate.
FrOSCon is a quite nice conference. Been there since the first year.
You have no idea what the relevant numbers are. The estimated loss of life during the Crusades ranges from 3-10 million lives. Current estimates place the Russian loss of life alone from WWII at 19.5 million.
Ok let's say they don't re-train. Let's say they just go out and try to find a job as phone sales people (yes, every single person replaced by technology decides to become a sales rep. Bare with me.)

What would that do?

It would drive down the salaries of sales reps by 2%. That's it. That's the magic of the market economy. That money saved by replacing people with software goes back into the economy and creates demand for more goods (which needs to be pushed by sales reps, for example.)

And by the way, I would argue that electrification and the industrial revolution were far more disruptive (and happened damn fast) than online shopping and bookkeeping software.
You missed the point of what I am saying, if you are debating on this minutiae.
What are the healthcare startups he's invested in?
You're right. We should allow companies as big and potentially malicious as Google to build the biggest walled gardens they can afford to support.

The constitution MacArthur oversaw specifically forbids a military[1] and despite recent attempts to amend the constitution this has not happened. However, the limit on a military force was later interpreted as provisioning a self-defense force, ergo SDF. It was intentionally limited so as to prevent Japan from immediately rising as a military power but to not require longterm occupation of Japan by U.S. forces[2][3].

So, like I said in the post (but perhaps didn't make clear enough) is that there are plenty of options for when scaling isn't too much of an issue. But you take a look at Twitter (Ruby/rails and now scala, I think? which kinda goes towards my point) and facebook (hacked up php and made it compile). My thoughts were focused on a language that you could start something small in (aka easy enough to use), but that could scale up reasonably well.
So what another 10 people will now have WP7 phone for a total of about 12 people (including Steve Ballmer and one mate of mine)?

Right on. I'm not sure I'd go so far as wanting the language to be as strict/typesafe as those (also calling Haskell an ML derivative is kind of funny, but I know what you mean)
I'm not clear on why, as a rational software developer, you find this chilling. If our economic system of choice depends on there being work for everyone, our economic system will need to be changed. This can be as gradual a process as anything else, but it is already happening. Welfare didn't exist in the US 100 years ago. Far fewer people went through higher education, and there was less spare money for scholarships.

Our efficiency as a species is increasing. This means that we will produce the same amount of work with less effort. If our distribution methods mean that this will cause poverty, we need to fix our distribution methods.
Regardless of Aiden's findings about solar energy his ability to see a pattern in tree branches and ten to attempt to answer the question why is impressive in my books.

With the wide media coverage this article received, it's fair to say at least 100,000 people saw the headline or read the article. Most of these people took the 'discovery' at face value.

It's conceivable that a tech writer at CNN, New York Times, or some other more mainstream news outlet was getting ready to hit the send button to their editor.

This post was credible, timely, and well reasoned. Whether he had second thoughts or not, I think the good done by combating misinformation outweighs whatever reason he had for taking down the article. Though I would have preferred to have linked to the original post.
Only if you don't change the single line of code it takes to not append the bundle identifier.
Perhaps? It's unclear that a JIT with type inference will give you better performance than compiling (especially if you were to do profile guided optimization) (sidethought: not sure if llvm has support for PGO).

Also, if most of your types are static anyway (which in my middling amount of experience, they tend to be), I personally would rather get compile time errors rather than runtime errors. But maybe thats just me.
>First note that the childless already massively subsidize parents through taxes that pay for education. Also note that I am considering replacement levels of fertility desirable.

This isn't as simple as that. The tax revenue used for education in Texas comes from property taxes. The majority of that is from homeowners. The overwhelming majority of homeowners have or had children in the home at some point. Aside from those facts, would you like to live in a society where the children were not educated? I think you would find that the reduction in crime and the boost to the cheap labor force would be worth the investment.

The most important point this should make is: all of these things are fabulously complicated and interrelated.
I blast put the most bogus half-witted garbage that could possibly half work, train of thought style. It just embarrassingly bad. I go back and clean it up almost immediately while it's still fresh in the mind.

The upside is that I usually find I need only 1/3 of what I thought I needed. It doesn't feel quite so bad to throw out huge chunks of stuff I know is so bad I wouldn't want anyone to see it anyway. The worst thing in a project is something I think is really clever but just not needed. I become irrationally attached.
My theory is:

- In 20 years, 80% of the people in will be kept alive by welfare, supplemented by their hourly job. Enough to get a small apartment, utilities, cell phone, cheap but unhealthy food, and shopping at the dollar store. And free tv/movie/music/book/sports entertainment via the internet.

- 15% will be the middlemen, extracting value from the others via service or thievery. They will be the new middle class. They can afford the sometimes luxury.

- the other 5.5% will be specialized knowledge workers. They will be the one maintaining the software/hardware to make sure nothing goes wrong. They can afford lots of luxury, but will be taxed heavily, as they are the only workhorse left in the society.

- 0.1% will be entertainers. They will make sure that people are entertained well enough not to riot.

- and the 0.4% will rule everyone.
The notion that using "real names" improves the quality of communication is not just wrong, it's utterly ridiculous. What it impels is that the (best? fastest? surest?) way get "better" conversations is to make sure that everyone is afraid of some sort of retribution for what they say. As far as I can see, that is the only thing "real names" achieve. After that, you can coat it any rhetoric you want, it still remain an ugly idea.
What I took away is the owner makes more money as she improves her workflow. And now that workflow is all haphazardly integrated software.
What if traditional brick-and-mortars business eventually turn to business models we frequently see on the web? What if robots drive costs down so low that you can have free hamburgers sponsored by some luxury product? Once you cut down human labor costs entirely, all that is left is natural resources costs. I'm just throwing out some ideas, perhaps someone with a better understanding of economics can elaborate or criticize...
> Browsr main objective is to make the browsers that default place to keep user data. Instead of you social connections being on Facebook's server or Google's server, it should be on your PC.

This. You describe browsr as being "like an operating system" in the post, but I think what you've said here is way closer to what you are demonstrating.

Also, I like this concept.

I doubt it. While it may limit your parent's capability (if he thought of it as a second language), I think it would a little presumptuous for him to imply it limits yours.

The Fed is not entirely independent of "dumb politicians" since it targets both inflation/deflation and unemployment. When politicians make exceptionally stupid decisions, such as borrowing too much money which results in a bubble of productive overcapacity that then pops and produces excess unemployment, then the Fed has to react by devaluing the dollar to bring unemployment under control. It would be preferable for it to have an adversarial relationship with the politicians in which it would raise interest rates when fiscal policy starts to get out of control in order to make sovereign borrowing too painful past a certain predefined level (such as a percentage of GDP) but this seems unlikely given that politicians are responsible for nominating and confirming Fed governors.
"When the rebuttal to your argument is The Federalist Papers, generally that means that you've lost the argument."

That is one of the golden lines of the article and so true. This quest for better targeting of ads is painful.

Also, I cannot wait until some of the folks on the reservations start getting flagged by Google. Many of the names people are know by violate Google's naming policy.
When I learned that, I found it extremely humorous. What was even funnier was that the extra U's showed up as Britain attempted to be more French-like. Isn't that a slap in the face today!
Analogies limp:

A few centuries ago, someone may well have remarked that many of the best businesses in many industries, were moving into office buildings, an invention that was only a few decades old at the time, and that office buildings were eating the world.

1. They would have been right.

2. Moving into an office building would mean that a business was keeping up, not that it was necessarily a good business with respect to other businesses.

3. It would have been a good time to be building office buildings.
That only eliminates the first two outside forces (investors, angels) in the list. You still have to deal with customers and employees - in other words, the market.
But a lot of companies don't need phone sales representatives anymore. They can do nearly the same thing with Adwords account and a decent landing page. Both of which can be setup for less than a days pay of a phone representative.

Pick another position that scales with production or demand and you'll invariably find similar automation that has been introduced in the past ten years.
To be honest, I'm rather interested in trying out a WP7 phone. The problem that I have is the fact that it's a huge barrier to entry to dish out hundreds of dollars just to test out a small device. I'm not in a position to be able to just dish money out like that, and I assume there are many people in the same boat as me. I guess that's the greatest burden to anyone trying to break into this market - everyone questions why they should dish out the same amount of money for x phone, when they could just get an iPhone for approximately the same amount of money - they already know everyone loves the iphone.

With that being said, I think Brandon Watson is doing his job extremely well - he is eliminating that barrier to entry and getting hackers using WP7 devices. Perhaps creating evangelists.

On a side note, Windows 7 has got me to switch back to a Windows OS, from Debian, that I had been running as my main OS since Vista came out. I'm just one guy, but Microsoft is doing some things right. Maybe they can make WP7 work?
I had a friend mention this to me before I wrote this, and it does seem pretty neat.

That said, I think it's big shortcoming to me (havent spent much time with it, spent ~10 minutes going through some of the demos) is that its a functional language. Personally, I don't mind haskell/sml/their ilk, but since I was trying to conceive of a language that people would actually use/adopt, it needs to be imperative and probably resemble something along the lines of C/php/python.

You need to work together with Google to gain access to the whole ecosystem, but nothing prevents you from having your own market and it may make sense in some verticals (like B&N does)
The article makes an interesting, but flawed point: The US is freaking out simply at the mention of socialized healthcare, socialized work would be dead on arrival...Ford’s solution requires that the wealthy consent to (or that the public impose) increased taxes to avoid economic ruin.

The flaw is the assumption that taxes would need to be increased. In the hypothetical world being described, humans have been more or less completely replaced by robots. This is a world of staggeringly high productivity.

It's likely that in such a world tax rates could be extremely low, and nevertheless the "virtual jobs" could provide enough revenue for all the virtual job holders to have very high standards of living.

Similarly, the 2011 USA could easily provide large numbers of people with a 1911 standard of living even if tax rates were much lower than they are today.

The argument of "mission critical" was once given for trains and planes and each had their bubble.

It was clear that the technology itself would succeed. This was the "core of truth" at the heart of each bubble.

The mistake was taking this to mean that one should invest in businesses pursuing those technologies.

In fact, the thing to do would have been to supply those industries, see general stores and the gold rush.

"free hamburgers...luxury product"

"As I look around, I see mass, systemic unemployment taking hold."

Only because we are paying people to not work, and because fair pay is illegal under a certain rate. Consequence is that work worth less than minimum wage cannot, by law, be given to people - and so automation moves in.

Stop paying people to not work and they'll find or make work. (There is a difference between a safety net and making lack of arbitrary wealth illegal.)

And "the poor", for most practical purposes, does not exist in the US. If you are living on more - a lot more - than the world median income, if you are flushing your toilet with drinking water, if you have a TV & car & cell phone & AC & thermostat heating & >1000 sq ft housing & ..., if you have over $1/meal/person/day[1], and etc you're not poor.

And still, in terms of competition for the "smartphone" customer, it was essentially only competing with the iPhone, and losing on everything but price. It took a couple of years to be comparable in "attractiveness" (features+look+easy of use .. the mix that customers want). The W7 mobile phones are losing on everything including price to both iPhone and Android. That's a much harder fight.

Microsoft might still be a contender in this game -- they spent some $5B and managed to attain that position in gaming despite a very late start (compared to Sony and Nintendo). Though you should remember Sony were resting on their PS2 laurels, and Nintendo were licking their wounds at the time. Both Apple and Google are still with a cut-throat we-have-to-win-this attitude, and they are strong opponents.
