I recieved this error when trying to sign up for coinbase and transfer my uBTC there:

You don't have that much - please visit the Buy/Sell page to add more funds to your account..

Any Suggestions?

Paypal or Bitcoin - though only a small number of businesses accept Bitcoin as payment.

Efficiency as well as integration with the native OS's style & interface.

HTML/CSS/JS + JQuery on the Front-end with Perl and my own custom Web package using XML files for data storage on the backend.

I have always liked the web as a platform because I can build something once and have it work across many operating systems/browsers/etc... and because the web is built on open standards.

One criticism people have of this approach to application development is that web apps aren't as efficient as native apps.

This pro/con discussion of web vs native apps reminds me of the C programming language, why it was created and what for.

The C Programming language was designed to be a portable language, meaning that it can be compiled on virtually any platform, any operating system. Yet C was also designed to constitute the minimum abstraction away from a given platforms native assembly language.

Thus a program written in C can be compiled on almost any machine, and run as efficiently or nearly as efficiently on that machine as a program written in that machine's native assembly language.

So perhaps we could use something like the C programming language for the web. A technology which allows us as developers to write our applications once in a portable open format, without needing to sacrifice in terms of performance.

Any thoughts?

> It's inextricable from cultural bias, though the physics obviously plays some role.

Of course, as you say, our cultural biases/values play a role in how we create music and what music we appreciate with how much consonance/dissonance.

But the fact that certain musical intervals sound more harmonious or more dissonant seems to be a result of the human ear's response to the physical nature of the frequency of the sound waves, and thus a response that is shared across cultures.

> The ratios for a tritone, major 7th, etc. are more complex

Yeah, I guess that's true that the ratios between those 12 frequencies aren't the 12 simplest, but they can be derived by following the simplest non-octave ratio - 3:2 or a perfect fifth - starting from a root note and moving up one perfect fifth 12 times.

Thus if you start from C: C - G - D - A - E - B - F# - C# - G# - D# - A#/Bb - F and that's all 12 notes. I guess I thought that because of that pattern those were the twelve simplest ratios. Thanks for the heads up.

And yes this principle applies to the Just tempered Scale not the even-tempered scale.

As to why some sets of notes sound good or harmonious and others sound "bad" or dissonant, we find that frequencies with the simplest mathematical ratios tend to sound the most harmonious, while frequencies with more complex ratios sound more dissonant.

So for example the simplest ratio 2:1 corresponds to an octave interval. Notes which are an octave apart sound so similar that we describe them with same letter. So concert A is 440Hz and the "A" note one octave higher is 880Hz.

The next simplest ratio, 3:2 corresponds to the interval known as a perfect fifth. So given the example of concert A at 440Hz again, one perfect fifth above concert A is the note E which has a frequency of 660Hz as (440 * 3) / 2 = 660.

We find the simplest ratios of frequency intervals present in music from cultures the world over. The traditional classical Western twelve-note scale consists of the 12 simplest frequency ratios. In some Eastern music we hear a pentatonic or five note scale, which consists of the five simplest frequency ratios.

So this aspect of music we can attribute to innate psycho-acoustics or even physics rather than cultural bias.

The model described here in this post sounds like a good start-up idea itself. Although you would need a fair amount of capital to mitigate the risk of company ideas that may fail.
