comment Decomposing a large text file, with alternating headers and text, into an array of headers and an array of text segments
best do StringSplit[.., StartOfLine ~~ "^"] in case the comment token happens to occur elsewhere.

you might want to put the comment mark back ie :> "^"<>title, then you could easily segregate them out with StringCases

comment curve on the surface
nice, but a bit of work to go if the curve is itself a 2d bezier you need to map the one parameter space onto the other.

comment curve on the surface
edit the question if you have information to add, but the is just a table of 2d points, not a surface

comment Fitting a numerical integral via NonLinearModelFit to magnetic data
the "no points satisfy" error comes from starting with w=.3 which conflicts with w>.3. By the way you can do one statement eg 20200 > Ms > 20000 instead of 20200 > Ms && Ms > 20000. Its not wrong as you have it but its a bit cumbersome to read.

comment Monte Carlo integration with random numbers generated from a Gaussian distribution
why don't you implement it yourself? There is a mathematica example on the wiki page by the way en.wikipedia.org/wiki/Monte_Carlo_integration. (I didn't study it but it looks like a good start )

comment DateList does not output the correct time, but Date does
So it looks like its giving you the standard time. Should be reported as a bug I'd say.

do this Read["!date","String"] then Close["!date"] I'm guessing its something to do with daylight savings time, but lets see how the sys clock is set in any case.
