I don't have the math handy but I've worked it out before -- when various groups send 'messages' into space from earth --- there's no realistic expectation another species will be able to receive it...we have trouble receiving massive, massive, EM sources that are millions of gigawatts at that range. We typically only do these' transmissions at thousands of watts at most..
They just hope that the alien species has some kind of super advanced receiving method....but most likely to receive a transmission from earth at that range would require a collection area like a parabolic dish the size of a planet.
So even communication is unlikely.
Yes, your example with three strings is better.
Thank you, Thief.
Using the StringBuilder class is better again if you need to dynamically build large strings of course..
But this discussion over String.Format proves my point...There's a very large amount of 'best practice' that goes along with any language. The longer you've been using a language, the more of these you're aware of.
Teaching mainstream languages would make it a bit smoother to enter employment, no doubt.
What's the big deal? One programming language is like the other, at least within the same paradigm. If you can program in Pascal, you can program in C. If you can't you learned a syntax and not "how to program". Basically, when I was a computer science student, we got one language taught for the concepts and the rest was just "swim or sink". That's the way it should be. I really have a problem with programmers who have problems switching from their preferred-language to another because it's unfamiliar. Well, no, it's not... It's the damned same thing with diverging syntax.
Basically, the premise of the Exam Board is quite right: the goal of programming is to have problem solving skills. Whatever language conveys that is completely uninteresting to me.
Oh, and just for the record: programming is just a small part of the computer science curriculum... or at least it should be.
There's a lot more that goes along with a language
Sure, if you know how to code OO, use iterators, understand switch statements and other language-related elements you can change languages and write an algorithm or two
But
Do I know best practice for everything?
If I'm a c# programmer. Do I know important differences between Ruby 1.7, 1.8. 1.9?
Do I know what the best inversion of control framework is? Or what the best ORM to use is? Am I familiar with how to use it?
If I'm a Ruby developer am I aware that in a.NET language if I add two strings together in c# "Hello" + "World" It constructs a new immutable string. But if I do String.Format("{0}{1}","Hello","World" it is much faster and uses less memory?
Will I know all the proper coding conventions, casing, tabbing, indenting styles.
There are hundreds if not thousands of useful pieces of language, compiler, and environment specific knowledge which is useful and can be pretty obvious if you do not have it.
I've been playing with c#, ruby, gcc. For around ten years commercially and I still need to invest significant re-education if I swap from say ruby to gcc or ruby to c# after a year..
There is a reason that people tend to stick with one or two primary languages.
I looked up phase interferometry and it was very interesting, thank you.
If you've got it patented. That means the detail is public anyhow right?
Why not just link us to the patent and/or go into detail?
Are you sure his measurements are good?
At the very limit to get 1mm accuracy you'll need wavelength 1mm or less.
Some quick calculations suggests 1mm wavelength = 299792458000Hz
Or roughly 300Ghz
This doesn't sound like something an 'amateur' could build on a weekend.
Unless you're claiming some magical way a wave can contain more information than its wavelength would allow
And the linux version is so much better
man launch
launch -[tc] -g [coordinates]
-t
Select thermonuclear warhead
-c
Select conventional warhead
-g
Change from lat/long to grid coordinates
[coordinates]
Grid coordinates. Just guess a few times and you'll get the format correct.
At first I was pleased with my new sight. I could finally see such beautiful landscapes and visages again...But why, why is everyone sitting around watching the text "Unlicenced Broadcast" on black monitors for an hour and a half?
In the traditional double slit experiment. We see interference if the particle may have past between one slit or the other. And we have no way of telling which. This creates interference between the two (possible?) waveforms the photon (may) have taken.
In this case. The two paths are. 1.) The photon was created by the first maxima 2.) The photon was created by the second maxima.
I'm not sure why which maxima created the particle is indeterminate. (Maybe because it happens too fast compared to the photons frequency.)
But the interference pattern generated is interference between those two possibilities. Ie I believe it's being suggested that the two possible waveforms of the two events are interfering across a small gap in time.

Sorry. I meant 1.) The /electron/ was created by the first maxima
2.) The /electron/was created by the second maxima.
Must of had photons on the brain.
