comment Error importing MBOX file
ram is not the only factor that limits sizes of things. use python to create some smaller files and see if you can import those. In the end Import is a black box and when it doesn't work there isn't much to do about it, but it would be useful to identify exactly what the limitation is. 2147483647 is the max for signed short integer just by the way.

comment Why is BinaryReadList faster than BinaryRead?
Having confirmed what you say, I think that may be considered a bug (or at least a documentation bug) that BinaryReadList[filename] reads from the beginning and does not change StreamPosition in the case where the named file is already open. (So far as I know all other low level i/o functions can use the stream object or name interchangeably )

comment converting Matlab program to Mathematica code
the only thing preventing your revised code from working is you need to initialize minfind and y1 as empty lists.

comment How to rasterize a Graphics3D expression into an Image3D?
good question , but I think the answer is hold your breath for wolfram to implement rasterize3d. (assuming you need a general solution.. if your graphics3d contains only simple objects there may be ways)

comment Error importing MBOX file
I suspect you need to look at external ulilities to see if they can parse it.

comment ODE of an eccentric circle
It seems like you know the expected solution. Can you plug it in the formula to check? Otherwise what makes you think the solution should have a simple form?

comment Scatter plot with smooth lines
you might want to give ListLinePlot the option InterpolationOrder -> 3 to mimic excel's "smooth line". (personally I would never use that for "data" )

Interpreter seems to give the ColorData["HTML"]["SeaGreen"] result..

comment Inverse of Interpreter[“Color”]: Convert a RGBColor to a natural language color name
This seems not so much a coding question as 'where do i get an appropriate training set'. Do you want to distill the answer down to a handful of basic colors (how many?), or do you want to feed it thousands of examples and likely get answers like "Crayola PinkSherbert". For the record I didn't downvote and I do think whoever did ought to explain.

comment Varying results from the Round function
do you still have a question? Note besides the floating point issue, Round rounds an exact .5 to the nearest even value, so the right answer one might expect mathematically here is {6.,6.,6.,6.}

comment Evaluation stops, no error
I believe for this case you will get better results if you treat it as nested 1d integrals, NIntegrate[ NIntegrate[ , {phi} ] , {X}]
