krop: A tool to crop the pages of PDF files
krop is free software, released under GPLv3+ in the sole hope that you or someone else may find it useful. It is written in Python and relies on PyQT, python-poppler-qt4 and pyPDF for its functionality. A unique feature of krop is its ability to automatically split pages into subpages to fit the limited screen size of devices such as eReaders. This is particularly useful, if your eReader does not support convenient scrolling. | |

LsToLi: Evaluating log-sine integrals
This computer algebra package for evaluating log-sine integrals in polylogarithmic terms accompanies the paper Special values of generalized log-sine integrals. Implementations for Mathematica as well as, less complete, for Sage are available. | |

PSLQ: A gentle introduction and implementation
The PSLQ algorithm finds integer relations among a set of real numbers. This is an introduction suitable for advanced undergraduate students. A very basic and naive implementation for Mathematica is also included. |
