Wcalc is a powerful arbitrary-precision calculator. It has standard functions (sin, asinh, logtwo, floor, etc), many pre-defined constants (pi, e, c, etc.), variables, "active" variables, command history, and hex/octal/binary i/o, conversions, and more
Arbitrary-precision CRC calculator and algorithm finder
CRC RevEng is a portable, arbitrary-precision CRC calculator and algorithm finder. It calculates CRCs using any of the 113 preset algorithms, or a user-specified algorithm to any width. It calculates reversed CRCs to give the bit pattern that produces a desired forward CRC. CRC RevEng also reverse-engineers any CRC algorithm from sufficient correctly formatted message-CRC pairs and optional known parameters. It comprises powerful input interpretation options. Compliant with Ross Williams'...

galculator is a scientific calculator in algebraic mode and RPN
galculator is a GTK 2 / GTK 3 based scientific calculator supporting algebraic mode as well as RPN. Features include arithmetic precedence handling, mathematical functions, different number bases (DEC, HEX, BIN, OCT) and angle bases (radiant, degree, and grad).
Please note: This project page at sf.net reflects the state of the project up to August 2015. Beginning in September 2015, the project homepage was moved to http://galculator.mnim.org, with the source code repositories and issue trackers hosted at https://github.com/galculator/galculator.
...It uses geometrically-based "turtle graphics" (well known from Logo) but is completely immediate and programmed using single keypresses (like Delta Drawing). No knowledge of the editor is necessary.
FElt is an open source system for finite element analysis, primarily for mechanical problems. FElt includes command line tools, an X11 interface for pre- and post-processing, and a Windows editor interface with some post-processing capabilities.
LaTeX Editor based on Bluefish (http://bluefish.sf.net). Main Features: (1) Autotext, Auto-Completion, Function References, Syntax highlight (2) External Tools (customizable) (3) UTF8 support. Winefish is a GTK+ application, released under GPL License.
