Lessons learned from past counterinsurgencies [pdf]

It's a lot easier to read if you paste the following into your linux terminal.

    wget http://www.princeton.edu/~ppns/papers/counterinsurgency.pdf
    cat << '    EOF' | sed 's/^    //' > pdfun2up
    #!/usr/bin/env python
    import copy, sys
    from pyPdf import PdfFileWriter, PdfFileReader
    input = PdfFileReader(sys.stdin)
    output = PdfFileWriter()
    for p in [input.getPage(i) for i in range(0,input.getNumPages())]:
        q = copy.copy(p)
        (w, h) = p.mediaBox.upperRight
        if w > h :
            p.mediaBox.upperRight = (w/2, h)
            q.mediaBox.upperLeft = (w/2, h)
            output.addPage(p)
            output.addPage(q)
        else :
            output.addPage(p)
    output.write(sys.stdout)
    EOF
