DRY

“It is tempting, if the only tool you have is a hammer, to treat everything as if it were a nail.” - Abraham Maslow


JRubyJava + Ruby


require 'java' pdf = com.itextpdf.text.Document.new para = com.itextpdf.text.Paragraph.new 'Brought to you by JRuby' file = java.io.FileOutputStream.new 'pdf_demo.pdf' com.itextpdf.text.pdf.PdfWriter.get_instance pdf, file pdf.open pdf.add para pdf.close

“You get true multithreading that can use all your computer’s cores from one process, plus a virtual machine that’s been tuned for a decade and a half.”
