Computer Algebra System written in Common Lisp
Maxima is a computer algebra system comparable to commercial systems like Mathematica and Maple. It emphasizes symbolic mathematical computation: algebra, trigonometry, calculus, and much more. For example, Maxima solves x^2-r*x-s^2-r*s=0 giving the symbolic results [x=r+s, x=-s]. Maxima can calculate with exact integers and fractions, native floating-point and high-precision big floats. Maxima has user-friendly front-ends, an on-line manual, plotting commands, and numerical libraries. Users can write programs in its native programming language, and many have contributed useful packages in a variety of areas over the decades. Maxima is GPL-licensed and largely written in Common Lisp. Executables can be downloaded for Windows, Mac, Linux, and Android; source code is also available. An active community maintains and extends the system. Maxima is widely used: annual direct downloads exceed 300,000. Many other users receive it through secondary distribution.

Extract text from corrupt DOCX files where Word itself fails.
Previously known as Damaged DOCX2TXT, this GUI program will extract text from damaged/corrupted Word 2007 - 2013 DOCX format documents. DOCX files are actually zipped collections of mostly XML files. The main text in docx files is found in document.xml file in the collection. Corrupt DOCX Salvager uses 7Zip, an unzipper that sometimes unzips partially corrupt document.xml files despite reporting an error. XML as a format is unforgiving of data corruption but Corrupt DOCX Salvager uses a Perl routine used to extract the text from the document.xml file which doesn't care about well-formed XML, a recovery stumbling block for Microsoft Word. Recent changes include the pretreatment of docx files with InfoZip's zip.exe -FF repair command, improving success rates. Also added are links to other solutions. If you are unsatisfied with the results, try my other corrupt Word recovery capable programs here on Sourceforge, S2 Recovery Tools for Word and Savvy DOCX Recovery.

A GUI for the 'pacman' package manager of Arch Linux
tkPacman is a lightweight graphical user interface for 'pacman', the package manager of Arch Linux. It is built with Tcl/Tk. As such it is compatible with all window managers and desktop environments. It only interacts with the package database via the CLI of 'pacman'. So, installing and removing packages with tkPacman or with pacman leads to exactly the same result. tkPacman is started using your normal (unprivileged) user account. You can browse through available and installed packages as a normal user. Anytime, you perform an action that requires 'root' privileges, you are asked to authenticate. tkPacman can use 'su', 'sudo', 'gksu' or 'kdesu'.
