comment Fibonacci Sequence Generator
Recursion, like you used in your first solution, may look like the most natural solution, but in practice its performance is just horrible. This is easy to see, as calculating f[n-1] implies calculating f[n-2], which you do again later on. Computing f[50] takes over 12 billion additions, compared to 50 when calculating iteratively. Fibonacci numbers are probably the best example where a perfect recursive definition is not a good idea to implement.

comment Mathematica ignores image orientation
Yeah, I haven't been there in years. (Too) busy with other things. However, every now and again I get an electronics question via my site (it's on my profile), and I still try to help people out.

comment Mathematica ignores image orientation
Thanks, Wizard (again! :-)). Works in version 9 too, but I couldn't find any of this information in the help system.

comment Artistic image vectorization
@Szabolcs - BTW, the word is search by image. There's a Firefox plug-in which I use almost daily.

comment Mathematica doesn't read .mat file
@Szabolcs - No, I don't have MATLAB. I have Mathematica, and my pockets aren't that deep :-).

comment Automatically zoom-out on ListPlot?
Should have added that I'm still on version 9 :-)

comment Automatically zoom-out on ListPlot?
It seems the "Axes->False" isn't required; apparently the Frame parameter switches off axes automagically.

comment Automatically zoom-out on ListPlot?
Fine, thanks. Not very much mathematica for the moment, and active in electronics, but not on stackexchange for the moment. Olin must have taken my #1 position long ago already :-)

Clever! Thanks a bunch. (I knew you would be here :-))

comment Automatically zoom-out on ListPlot?
@kguler - I almost felt embarrassed that I didn't find that, but it doesn't do the trick: the points remain on the axes. Oddly, in the help file example it does exactly what I want. Thanks for your reply, anyway.

comment How to set an absolute path name using SetDirectory?
@seism - 'fraid not. I didn't do anything to make it work, I just noticed it does! :-)

comment Kernel crash after idle in version 10.0
This is at least the third different crash report of version 10 here in the last 8 hours alone. I think I'll postpone my upgrade until 10.1 :-(

comment How to set an absolute path name using SetDirectory?
@seism - I tried it with a single backslash, and it also works. No error, no warning, no prompt.

comment Can I change the font of all elements in my barchart with one property?
Thanks a bunch. I presume the "14" is supposed to change the font size, but it doesn't do anything, not even when I add "FontSize->" in front of it. This did work for the BaseStyle solution you suggested in comment.

@MikeHoneychurch - This doesn't seem to change the font for the legends.

@MikeHoneychurch - Thanks again. Not sure about merging; the data is the same, but here it's about the font globally, which wasn't in the other question.

@magma - Apparently not, but I saw them in a notebook I got from WRI, and I sticked to it.

Did you know there's a mathematica.stackexchange? I've flagged for migrating it there.

comment Have the Random functions changed?
@Artes - Thanks, I'll look at it. Any reason why it's better than Partition (which works now)?
