make your own mopp

If you
want to make your own ‘My Online Publications Page’ (MOPP) similar
to mine here’s what you have to do :

  1. in case you are running
    Linux, all you need is the mopp package and
    follow the instruction on this page.
  2. if you are onto Mac OSX you have to get and compile a few more
    packages. To start, go to the BibTeX bibliography tools page and
    download the bibclean file. Go to
    the directory, do a ./configure and a
    make and copy the resulting executable bibclean to the
    bibtools/bin folder of your mopp-folder (see first
    step).
  3. get the latest gawk package. Do a
    ./configure, then a make and a
    sudo make install and gawk gets installed at
    /usr/local/bin/gawk. Make a symbolic link (or use a
    bruteforce copy) to /usr/bin/gawk.
  4. Make a
    symbolic link or a bruteforce sudo cp /bin/ksh
    /usr/bin/ksh
    .
  5. If you are using only scanned
    pdf-files it is sufficient to get DjVu-versions of them using the Any2DjVu service. If you want
    to do the conversion from Pdflatex-files yourself, get the DjVuLibre package, configure,
    make and install it as before. All programs get installed under
    /usr/local/bin, write down the files in the
    djvu/bin folder of the mopp-folder, remove them and
    copy your compiled version of them from /usr/local/bin to the djvu/bin
    directory.
  6. Open the work/mopp.sh script of
    the mopp-folder in an editor, comment out the recode
    line and change the awk line into
    awk -v
    THENAME=”$MOPP_NAME” -v
    THELOGO=”$MOPP_LOGO” -f bib2html.awk \
    (that is
    add a space after the two -v options).
  7. You should now be
    able to follow the remaining instruction from the How to make “My
    Online Publications Page” page
    to get a mopp-page which looks
    roughly like this one.
  8. If you want to change the layout of that page, you should
    modify the work/bibtex2html.awk file to fit your taste.
    If you want to have a layout similar to mine email me and I’ll send you my bibtex2html.awk file.

MyLife@300dpi

Three years ago I did spend three weeks next to my Canonscan, painstakingly scanning all individual pages of every preprint I ever wrote. Next, I converted every page to PDF, resized it (in order to control the size) and bundled them into PDF-files. A typical preprint would take me roughly three quarters of an hour and the final result was mediocre. For example, here a blown-up sample from the original 1992 ‘Moduli
spaces of right ideals of the Weyl algebra’ -preprint, resulting in a 1.7Mb PDF-file

Recentlty, the department bought a Ricoh-copier which makes scanning a lot more fun. To scan a preprint at 300dpi and convert it into a single PDF-file takes under a minute (actually, downloading the file using a web-interface takes longer…). For this particular preprint, the resulting PDF-file took up 1.2Mb and looks a lot nicer

Still, 1.2Mb is a huge file but converting it to a DjVu-file (DjVu=deja vu) using the handy Any2DjVu Service gives us a mere 236Kb file which comes a lot closer to the filesize of a PDFLaTeX-file and the output is still very legible

So, I decided to rescan my entire life at 300dpi and convert it into DjVu. Next, I got the MOPP-package (MOPP = My Online Publications Page) working using the instructions from this page and some obvious MacOSX-modifications (if I can do it, so can you but perhaps I’ll write up the details in another post, just to remind myself). You can see the result at my homepage. I’ll update the latter one regularly (there are still some preprints missing, as are all my courses etc. and cross-references) and only afterwards I’ll update my homepage again. So far there is 250Mb to download (including all versions of the noncommutative geometry@n book, including the published ones…) so this should keep you busy for a while…
