Mathematician: Is Our Universe a Simulation?

Rothron the Wise Maybe it's better not to find out... (745 comments)

If we find out it's just a simulation, it might ruin whatever result the simulator is looking for, and we'll get shut down!

Has Flow-Based Programming's Time Arrived?

Rothron the Wise The Code is the Model (268 comments)

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.

Cloud Computing Democratizes Digital Animation

Rothron the Wise Re:a bit naive (167 comments)

Also, CPUs are so fast that Pixar is mostly IO-bound, which is something the cloud won't solve for you.

Geodesic Gingerbread House Template For the Holidays

Rothron the Wise It's not a geodesic dome! (61 comments)

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.

Rosette Wins Loebner Prize 2011

Rothron the Wise Rosette speaks with to Cleverbot (57 comments)

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.

FPS Benchmarks No More? New Methods Reveal Deeper GPU Issues

Rothron the Wise Re:Feel of a given fps value (125 comments)

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.

Camera Lets You Shift Focus After Shooting

Rothron the Wise Big tradeoff (155 comments)

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.

World's First Full HDR Video System Unveiled

Rothron the Wise A lot of confusion about HDR. (107 comments)

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.

Why Special Effects No Longer Impress

Rothron the Wise CGI getting better (532 comments)

But kinetics are still off when motion capture isn't being used. We need tools that limit the animator to work within the acceleration limitations of what's being animated. Too fast acceleration is usually what gives a CGI shot away. It robs objects of their weight.

Toshiba To Launch No-Glasses 3D TV This Year

Lenticular lens 3D is pretty awful to look at, with artefacts galore. I'd wanna see this TV before I buy.

Robotics Prof Fears Rise of Military Robots

Rothron the Wise I have doubts (258 comments)

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.

Hubble Releases First Post-Upgrade Images

Rothron the Wise Re:Colors in photographs (129 comments)

Sometimes they are false colors, often they are not. However, a telescope is vastly larger than your eyes. They gather a lot more light, even considering how much the image has been magnified.

I've watched the ring nebula through a 11 inch only to see it in black and white, yet fixed a camera to the very same telescope and gotten color pictures. There simply isn't enough light for my eyes to detect the color. Perhaps with an even larger telescope I could have.

So no, the spectacular nebula might not even be visible to the human eye in your parked space ship, but you certainly could take a long exposure with a very sensitive camera and get awesome colors.

The Orion nebula is large/close enough to be seen without any telescope, but too faint to see without.

Artificial Brain '10 Years Away'

Rothron the Wise Does a human brain a human make? (539 comments)

Babies don't do a whole lot after they are born. Perhaps they can model an adult brain from the start, but I doubt it will act very human without years of experiencing the sensory
input of a human body. The way the human senses are wired to the brain I suspect has a lot to do with how the brain is segmented into areas with specific tasks. What a human brain-like lump of simulated neurons will be able to do is anyones guess. I'm sure looking forward to any experiments, even though this opens up a pandora's box of ethical dilemmas.
Will the simulated brain feel pain? Have fears?

Henry Markram seems too optimistic, but if he's right then this might be the starting shot for the singularity.

Black Holes From the LHC Could Last For Minutes

18% of Consumers Can't Tell HD From SD

Rothron the Wise Re:Motion blur (603 comments)

Actually, PAL is usually 50fps. Films on PAL are shown in 25fps, slightly faster than in a theatre, but not enough to notice unless there's a side by side comparison.

This also means that movies on DVD differ in runtimes depending on the zone.

18% of Consumers Can't Tell HD From SD

Rothron the Wise Re:Frame rate (603 comments)

Some high end TVs can be set to detect motion vectors between frames and create new in-between frames.

This doesn't work perfectly however, and may in some cases cause disturbing artifacts. Sony calls their technology MotionFlow and I usually turn it on when playing PS3-games.

MotionFlow does a few other things aswell like reverse 3-2 pulldown, but that's pretty irrelevant for me since we have 50Hz TVs over here.
