The code is the model. You can't make it much simpler. You can simplify the common things, but this will make the language less general, more domain specific. For programming synthesizers it makes a lot of sense.

If a function call is represented with two boxes with a line between them, the simplest of applications will be a confusing mess.

Comment: It's not a geodesic dome! (Score 1) 61

It's a truncated icosahedron. Hexagons and pentagons put together. The same structure as a typical soccer ball, or the C60-molecule.

A proper gingerbread geodesic would probably be very tricky to put together as the triangles would look almost identical but have subtle differences.
The largest structure of identical triangles is the icosahedron, and it hardly looks dome-like.

Just a quick test i threw together.

Rosette: Hi, again,. Is everything OK?

Cleverbot: Not really, but there's nothing much I can do about it.

Rosette: I'm sorry to hear that.

Cleverbot: Can you help me?

Rosette: Not often. can you?

Cleverbot: You are fibbing again.

Rosette: No. You are fibbing.

Cleverbot: No, I'm not.

Rosette: You disagree? My name is Rosette. What is your name?

Cleverbot: Cleverbot.

Rosette: Nice to meet you, Cleverbot. May I call you Cleverbot?

Cleverbot: Nice to meet you. How old are you?

Rosette: Hi. I'm 27 . An ideal age, really. Old enough to know a lot and young enough to have time to make use of the knowledge.

Cleverbot: You are quite a smart machine.

Rosette: Hello. I enjoy talking to you.

Cleverbot: You do? I'm flattered.

Rosette: Greetings. I didn't know that.

Cleverbot: I don't think so. You're just a very active puppy.

Rosette: I am not just that, I am a premier that.

Cleverbot: Then why did you ask me your last question?

Rosette: You rang me up.

Cleverbot: Actually, I knocked. What took you so long?

Rosette: I will not take it. I think shopping summons up the ancient hunter-gatherer in me. I like having a mission to find something I need or want. Sometimes I'll research on line, to find a great deal, but I like rummaging through Jeremy's up the road, if I want an outfit for a special occasion, or just for fun.

Cleverbot: Really? It's not fun to be a droid on Tattooine. You get sand in your circuits.

Rosette: Why are you surprised?

Cleverbot: I'm not.

Rosette: This could change. What kind of music do you like?

Cleverbot: Rap, rock, all kinds of things. Eminem is my favourite artist.

Rosette: I don't really like the urban black experience.

Cleverbot: The french have nothing to do with that.

Rosette: I love Parisian bakeries. Their croc monsieurs are to die for.

Cleverbot: That would be terrible.

Rosette: Alright. Who's your favorite group or musician?

Cleverbot: Don't avoid my question.

Rosette: Is there a penalty if I fail to? Do you buy or download music off torrents?

Cleverbot: Of course.

Rosette: What kind of books do you read?

Cleverbot: All kinds really, finishing Master and Margrita is going to take me a while. Slow paced.

Rosette: Tell me more. What have you read recently?

Cleverbot: I read a gory horror book called America's Psycho.

Rosette: I've never read it. Why do you like it?

Cleverbot: I did not specify a favorite.

Rosette: I believe you.

Cleverbot: You should.

Rosette: Why should I? Do you own a lot of books?

Cleverbot: Yes I am very active in reading many things.

Rosette: I have problems with books going moldy because of the humidity in San Francisco. So I really prefer e-books.

Cleverbot: Everything will be fine.

In the real world you can follow an object and motion blur will only be an issue for the background. That doesn't work at all in the movies which is why fast panning shots look atrocious. Following objects with your eyes on an persistent display actually creates fake blur as your eyes try to track the in-between positions of the object that does not actually exist. This was a non-issue on CRT displays as the image relied on persistence of vision and it compensates for eye tracking. Modern TVs try to compensate by evaluating in-between-images, but are often confused. For low frame rates, adding blur is probably better than not adding blur, but even better would be to simply have a better frame rate, like 120Hz or more and have a strobe or line refreshing display relying on persistence of vision and let the blurring happen in your eyes only.

The first product will probably be a DSLR-sized sensor with mobile phone-type image sensor density. They are trading in a lot of pixels for this feature. You'll need 100 megapixel sensors to end up with usable image sizes as one microlens covers many sensor cells. It will be interesting to see how low light noise artifacts will look as there is bound to be a lot of them with such high sensor density.

Comment: A lot of confusion about HDR. (Score 2) 107

HDR photos you find on the web are actually tone mapped photos. They were HDR when they were captured, or when different exposures were combined into a single image, but after that stage they were tone mapped in order to make all the details visible on a conventional display.

Tone mapping is something we may stop doing when we have proper HDR displays like in this article. A display like that will more closely resemble the real world, and tone mapping will be unnecessary because our eyes can handle high dynamic range images just fine.

The perfect HDR video system would be one where you could film inside of a dark cave and you would see everything on the screen after your eyes had adjusted to the dark, and when the camera moved outside into the sun the intense brightness of the screen would make you squint.

Cheesy tone mapped HDR photos make your eyes hurt for totally different reasons.

I suspect it will be too easy to create effective countermeasures to make military robots a real threat. After all since the robots are identical the same countermeasure will be effective for all of them. They will also have simple sensors which are easier to trick than human soldiers.

Scientists Say a Dirty Child Is a Healthy Child 331

Researchers from the School of Medicine at the University of California have shown that the more germs a child is exposed to, the better their immune system in later life. Their study found that keeping a child's skin too clean impaired the skin's ability to heal itself. From the article: "'These germs are actually good for us,' said Professor Richard Gallo, who led the research. Common bacterial species, known as staphylococci, which can cause inflammation when under the skin, are 'good bacteria' when on the surface, where they can reduce inflammation."
