- PDF/PNG Astrological Chart Service
This form generates nice-looking astrological charts in PDF or PNG format. It's
mostly a demonstration of my horoscop and
starfont astrological typesetting packages for LaTeX, but the hope is
that the charts will also be useful for general purposes even for non-users
of horoscop. They compare favorably to those generated by the other free
online chart systems I'm aware of. This system does not provide any
interpretation; for that you'll have to look elsewhere. See the FAQ for
instructions, privacy and other notices, and other information.

- How to concatenate PDFs without pain
- In my work I recently had a situation where I needed to concatenate several PDF files into one big PDF file. That turns out to be a much harder problem than it sounds, and the Web isn't as helpful in solving it as should be the case. Here's a summary of what I've discovered on the subject, so that someone else who wants to append PDF files on a real computer won't have to go through what I went through. This page covers only software that will run under Linux and similar FLOSS environments. (9 January 2007)
- Postscript and PDF tricks for free software users
- My PDF concatenation page is quite popular, and I recently had occasion (while publishing a book through Lulu) to need a couple of other hard-to-find Postscript and PDF-related techniques, so I'm recording them here in case they're useful to others. (22 June 2006)
