LSE1234

I am a web developer...learning Russian online, may study some FORTRAN since I have some interest in scientific programming, what you recommend to do (what version study, what study?)? I have an old schaums FORTRAN 77 textbook 1995(c)....

I read many from IPad (PDF, html pages - Online material etc), and also have PHP, Java (SE/EE) and jQuery skills...

you know any site with free FORTRAN programs open source?
