hey I''m trying to find a way to convert images that were uploaded using file_column *before* file_column generates a thumb and copies them to the final dir - this because 50x50 is pretty small and png would be a much better format (in smaller dimensions) than jpg or gif. This is what i have in my model (using rmagick for the conversion): file_column :image, :magick => {:versions => { "thumb" => "50x50" }} before_validation :convert_to_png...

I use AfterStep on Linux. I made an R.xpm file (attached) and put this icon in the "wharf". To invoke R I click on the R icon. I did not find an offical R.xpm, and so I am submitting this one for your collective consideration.... The idea behind the icon is that it looks like a scatterplot, which is "statistical". My main beefs with my R.xpm are that it doesn't have a

Is someone working on a 3d vizualisation set of functions ? I read dream dream dream in PROJECTS about 3D GRAPHICS. When I want to visualize 3d data, I use Geomview but with a dataset greater than 50x50 that's too hard for my poor computer.
