comment Test on classical guitar sound board vibrations of different brace pattern
If STL is plain text and not too large pastebin.com could be a choice. Otherwise, dropbox and thelikes.

You have to provide the STL on some third party site. You can't upload it on Stackexchange.

comment How can I write a function whose argument is a date, and whose output is the average temperature for the day?
I'm afraid that if you want to learn programming in Mathematica you have to read the documentation. In addition to the links above try this as well. This site is not meant to do your homework for you, but we can help when you get stuck.

Have you seen WeatherData? If you just want to write your own function have a look at this.

comment Why does Mathematica simplify $x/x\to1$?
My V10 (Win7-64) also returns Sign[x]. Perhaps you should restart.

comment Communication between local kernels
In V10 you could perhaps use the cloud (using CloudPut and CloudGet) to share values. Of course, this is useful only if the calculations are expensive compared to communication.

comment Problem with cross product of two columns
Your problem is that you think of column and row vectors. Mathematica doesn't have (and doesn't need) such a concept. I wrote a bit about this in this answer.

comment Convert spectral distribution to RGB color
@AlexeyPopkov I forgot to copy the line of code that gives the downloaded wavelengths the proper size (nm). Added now; thanks for pointing this out.

I don't see this in 9.0.1 Win7-64 either

That's all in the documentation, you just have to read it.

comment Convert spectral distribution to RGB color
@mr.wizard. The question isnt really that complicated. If there aren't any answers by tonight I'll give it a try. Shouldn't take more than 15 minutes.

comment Test a wooden board's vibration mode
At the least the OP could provide (links to) the equations describing the vibration, or do we have to do the whole (home)work ourselves?

comment Median of Dataset in Mathematica 10
Looks like a bug to me. Have you reported this to support@wolfram.com?

comment Export dataset to JSON
The JSON doc page says: Export["file.json", expr] exports a list of rules to JSON. Clearly, a Dataset is no such thing. Your "workaround" does the required conversion to this list of rules in a straightforward manner. I wouldn't call it a workaround, as there is no bug to work around.

comment Computing and plotting a spectrogram in Mathematica
@xslittlegrass Right. BTW version 9 has more tools for making these kinds of plots (see Spectrogram and Periodigram).
