Indeed children do have a great ability learning new things, however, they often lack the level of abstract thinking needed for doing some real programming. But how many people grasp the difference between a set and a list? And how many people confuse concepts like "object" with "class", or understand the "pointer-to-pointer" concepts?
Although I have a M.Sc. in Computer Science and taught myself LISP in 1979, I could not make sense of Squeak after I downloaded it. Yes, I could play around with it, but I failed to figure out how to write a program using it. I wonder how this can be the ideal programming environment for children.
Squeak/Smalltalk is just another programming language and can hardly be seen as something that would revolutionize PC use. I agree with the observation that the current state of computing has not improved much in the past twenty years. And I too think it is due to how it has been commercialized. But I do not know an easy way out.
Thanks for the clarification of my slightly complex sentense, but really it does not state that Brinkhorst and Bolkestein belong to the same party. It states that all parties voted against, except one (VDD, where Bolkestein belongs to), and that the party (D'66) that Brinkhorts belongs to voted against. So it must be clear that they do not belong to the same party. Please note that the sentense starting with "except" is between comma's, and is thus an intermediate sentense.
It still might be miles long, and have considerable weight. If someone would walk against it while it was laying on the ground, there must be some tention, even if you assume that the thing has almost no friction. As an experiment you could roll out the contents of a case tape and drap it along a road and see what happens when you pull it away in the middle.
Minster Brinkhorst does not feel obliged to changes his 'yes'-vote into an abstination", according to Joop Nijssen, spokesman of the Dutch EU-representation in Brussel. This against the desire of the Dutch parlement. The minister is still seeking way to implement the degree that was filed by the parlement to withdraw the 'Yes'-vote. The degree is supported by all parties, except the party the Mr. Bolkestein belongs to, thus also the party that Minister Brinkhorst belongs to.
So far, I have not heard any report in the normal media about this political conflict which has been ongoing for some months now. Appearantly, the normal media does not consider it as news, probably because they do not understand the issue.
Which is a very sad things.
And what if the tether breaks and drops on Earth: a wire so small you can almost not see it, but stronger than any other material. It will acts as a knife and cut through almost everything. A sweeping tether could make a whole area unhabitual. Very dangerous stuff.
The best solution, also with respect to scalability, is to implement an application server, which might run on the same machine for that matter as the database server. Go for a three-tier solution. Implementing business logic at the client is a bad idea. Implementing it as stored procedures is a less good idea.
The only reason we program is because performance is an issue. If we would have automatic systems for making specification executable, we would not have to write programs. One of the reasons, I believe, that we do not have such automatic systems is that they would not perform. We need human optimizers, people like you and me, that can before the necessary optimizations. The von-neuman computer architecture is rather slow, it is only because of the memory piramide that it is able to perform reasonable. 90% of code is dealing with moving data around different types of memory (registers, cache, RAM, hard-disk, network) and doing differentials queries, e.g. changing the result of the query when the underlying data has been modified. The screen for example, is not completely computed when we move the mouse around, or with every keyboard hit. Only the area that is changed is refreshed. And this is just one of the examples. My conclusion is that the only reason we program (and not write specifications) is because performance is an issue.
I too cannot force myself to believe something that I know cannot exist, or is a logical contradition. And I agree with you that it is impossible to proof through science or philosophy that God exists or not. But there are things, like my awareness, for which I so far have not found convincing scientifical explaination. Note that I am talking about awareness, not about consciousness. I would describe consciousness of the consistent model that we have of (possible external) world. Awareness is the sense of being aware of it. I believe it is possible that you can have consciousness without awareness, and that I do not have a scientifical method to proof that anybody else outside myself is aware or not.
This problem of awareness really bugs me, and I believe that it reason for me to accept the possibility that there is something outside the physical world as we precieve it, and that it possible that some God does exist. I have come to the conclusion that I am a skeptical theist. I also believe that I am not the only one. I also have discovered that not all atheist are skeptics and that believing atheist exist.
If you want to have your own "real" random number source (not pseudo-random), have a look at LavaRND, which make use of a simple webcam as a random noise source.
The whole idea of Load and Save is from stems from a time where loading and saving took considerable amouth of time. Why do I have to press "Save" all the time. Why can't my edits be persistent right on. Save and load should be replaced by open and close together with a undo function. Normally you want to save your changes, and only in case of an error you want to undo your mistakes.
We live in a society where the lack of social skills has a much greater impact than the lack of technical skills. When we all were still farmers we had to plan, count, learn how to do things in order to survive. But now it are the managers, the advisors, the marketeers and the sales people who earn more than people with technical skills. Furthermore, we live in a highly individualized society where an individual without the proper social skills is easily going to lose from those that do have these.
I get the impression it is about the same you can do with a cheap webcam at the same focus distance. I took some interesting pictures of bugs with a Philips webcam that can focus at about an inch.
In a sense I am a great fan of the idea of a semantic web. But I am affraid that it does not work in reality. As soons as it gains some momentum it will be hyjacked by large companies (MS, Yahoo) trying to commercialize it and by small companies trying to misuse it (spam).
A struct is exactly like a class, except that a class starts with private, and a struct with public. "struct{" is thus equivalent with "class{public:".
It seems NASA themselves are also getting lousy with putting all the raw images on the website. I get the feeling that some are missing. Are they affraid of others putting the color images together before they do themselves?
This argument is completely of the mark. The brains does contain specialized areas for detecting the delay. For low tones the spikes produced by the detecting hair cell, match the wave front. These are than transported to an area in the brain where there is a line of cells where the signals from both ears are at opposite ends. The cells where the signals arrive at the same time (depending on the delay caused by the spike to travel through that cell in the line) produce the strongest response and determine the direction from which the sound originates.
I agree with you that most object models are crippled. But I was speaking of a "solid object model with a clearly defined semantics". Most common used object models lack clearly defined semantics in terms of mathematics. Please read my Object-Oriented Considered Harmful and my article on Art of Programming.
...that are designed from the bottom-up, instead of top-down. Whether a OS makes us of a file-system or a relational database to store data, is really not interesting from the perspective of the end-user (application programs). The same is true for so many OS related design decisions.
If you want to be truely revolutionary, you should take the top-down approach and start with a solid object-model (with a clearly defined semantics), and only then start thinking about how to implement the rest.
Distance actually does not matter with respect to the method used to measure the temperature, as long as you have enough light, and there is no disturbing medium in between. Both conditions seems to be met.
So the real bad thing is that the president of the United States has too much economical power, and that the people of the United States appearantly do not elect a president on the basis of his abilities with respect to economics but on some other grounds.
Personally, I think the whole problem comes from the way votes are counted by district (state), which leads to a two party system.

Maybe the should have included an online encyclopedia, such as Wikipedia, in the investigation as well.

Really interesting invention, but this was already mentioned in "Dune" by Frank Herbert where it talks about oil-lenses, if I am not mistaken.
Launch has been delayed to strong winds at high altitudes.

Due to it large unpopulated areas, the only suitable means of transportation is often to fly by plain instead of driving by car.
