Your benchmark only shows that Fortran computes the square root faster... I'd be happy to see a more complete benchmark though. Also could you post the code for this one?
@Hubie and @gunksta you should really try reSTructrured text as I suggested in my previous post. One of the reasons I like it is that you can convert the source to odt and odp, which can then be...
You could also use reStructuredText http://docutils.sourceforge.net/rst.html. It is a markup language that can be converted to latex, html, pdf, odp and odt documents.
It is not as versatile as...
That's a good point! A lot of the security problems occur when the user does something stupid then it doesn't help even if the OS is secure. So Ubuntu doesn't save you from e.g Phishing.
If you...
I don't think there is a real reason why you should learn bash instead of python. I'd recommend going straight with Python and if you do need bash then it is easy to pick up. A lot of Python packages...
You can do what you want quite easily with Qtimer: http://www.riverbankcomputing.co.uk/static/Docs/PyQt4/html/qtimer.html. Here is a quick example...
There are some video tutoriala available here: http://vcasmo.com/user/drewconway. Have fun with learning R!
I'd suggest that you use Python with SciPy for this. Here is a simple example of filter design: http://mpastell.com/2010/01/18/fir-with-scipy/. Not hard at all!
Academic Earth has load of good algebra lectures: http://academicearth.org/subjects/mathematics
I'm not sure that this gives you all that you wan't, but you could use restructured text to take notes and convert it to a website with rest2web.

I'd suggest using GNU screen: http://www.gnu.org/software/screen/
screen
matlab -nodisplay -nodesktop -nojvm -nosplash

OpenCV is a good library for machine vision, but you'll have to know how to program http://opencv.willowgarage.com/wiki/. It has good examples to get you started and there are also python bindings...
Looks very interesting, I'm going to try it straight away! At least for the Mac version would be very useful :)
@engelp I prefer to use an IDE for interactive data analysis before I make a script out of the whole thing. Or if I just wan't to do some exploratory plotting etc. Of course don't need to use and IDE...
Interesting discussion everyone!
As I see r-recommended contains the recommended packages that come with R-source and are installed in all platforms. If we wan't to add Rcmdr to r-recommended...
I don't think it is not possible to port the win or mac version to Linux, so achieving a similar GUI would require writing a native Linux app using either Qt or GTK. And ideally get it included in...
Its good that you brought this up and thanks for the long post. Having a menu entry for R would definetly be a good idea for newbies.
Given that the tkGUI is really limited I would rather add a...
I haven't actually used either, but from what I have read they seem intresting. From what I read reStructuredText can be used to write a whole book with bibliography, tables and images and you can...
Have you tried using restructured text or markdown? Their idea is a bit similar to latex, but both offer conversion to odt and latex.
I had the same behavior with matplotlib 0.91.2, but was able to fix it by upgrading to the newest version 0.99.1. It is easy to install from source.
I second Latex. It takes care of numbering of headings, figures etc. automatically so its really easy to move your bits of text. The only problem for me is that not all Ag journals accept Latex...
I came across some interesting use of the twitteR-package http://www.drewconway.com/zia/?p=1471 :) I found the link From Twitter of course..
I have started to follow R posts on Twitter and found some nice links that I never knew about. I highly recommend it to all R's friends :)

You could also use Matplotlib to get better Latex output:
