comment Can't type in notebook in version 10
The same thing happened to me a couple of times (also on OS X). Quitting Mathematica and restarting it fixed it both times. Interestingly, when I quit, it put up a dialog to save a few of the notebooks, and there I could interact with it (to click on yes or no). Very strange.

comment Integral of x^p
Oh right that's why it doesn't work in mathematica. Oops, pattern recognised the wrong thing, I'm an idiot sorry.

comment Integral of x^p
Actually the log is recovered in the limit. It's just that mathematica doesn't recover it correctly.

comment Integral of x^p
Well, $\lim_{p\rightarrow -1} \frac{x^{p+1}}{p+1}=\ln(x)$. Not that mathematica knows this, though (try Limit[x^(1 + p)/(1 + p), p -> -1])

comment What are the best tips in Michael Trott's beer/whiskey Wolfram Blog post?
@Artes While I meant my question as a joke (you were completely direct, the "joke" was to ask for elaboration on something completely explicit), I agree with the overall sentiment.

comment ToExpression from commandline
I think it is a bug, in the sense that eg Plot[Sin[x],{x,-5,5}] doesn't cause mma to hang. So, while I agree that the fact that it fails is not a bug, that it hangs seems to be. Or am I missing something?

comment Importing multiple images for machine learning classification
something like Import[#] & /@ FileNames["folder/*.jpg"] is what you want. Mathematica has about 3 gigabytes of documentation.

comment Finding average error of the data
@Mike a) that code doesn't work unless I know temp, b) is it too much to ask what doesn't work with LinearModelFit or the NonlinearModelFit example I gave?

comment Finding average error of the data
If, for example, dat = Table[{x, Sin[x] + RandomReal[{-.2, .2}]}, {x, 0, 10, .1}]; (because the code you gave needs a location and other parameters and I don't know, nor want to learn, how to set that) then eg mdl = NonlinearModelFit[dat, a*Sin[b*x] + c, {a, b, c}, x] finds a model and you can find for example the variance like so Variance[dat[[All, 2]] - mdl /@ dat[[All, 1]]].

@Mr.Wizard OK, as you can see I did not vote for it to be closed. Maybe you're right.

comment Test a wooden board's vibration mode
@Mr.Wizard Also, it's not that unreasonable to expect that the answer to this could be modified to apply here. Does it? Does it not? Why not? We're not told.
