Cura is a slicing software from Ultimaker. A slicer generates G-Code for 3D printers.

MIT Photonic-Bands (MPB) computes definite-frequency eigenstates (harmonic modes) of Maxwell's equations in periodic dielectric structures for arbitrary wavevectors, using fully-vectorial and three-dimensional methods.

Valeronoi (Valetudo + Voronoi) is a companion for Valetudo for generating WiFi signal strength maps. It visualizes them using a Voronoi diagram.

This package contains all part definitions that are required for Fritzing app.

The OndselSolver library for assembly constraints and multibody dynamics is used by FreeCAD 1.0.0 for its new Assembly workbench.

Radare2 is a complete framework for reverse-engineering, debugging, and analyzing binaries. It is composed of a set of small utilities that can be used together or independently from the command line.

Radare2 is built around a scriptable disassembler and hexadecimal editor that support a variety of executable formats for different processors and operating systems, through multiple back ends for local and remote files and disk images.

It can also compare (diff) binaries with graphs and extract information like relocation symbols. It is able to deal with malformed binaries, making it suitable for security research and analysis.

PyVISA is a Python package for support of the VISA, in order to control measurement devices and test equipment via GPIB, RS232, Ethernet or USB.

Scikit-rf, or skrf, is a Python package for RF and Microwave engineering.

A C++ library for rigid body kinematics calculations and representations for kinematic structures and their inverse and forward kinematics solvers.

GNU poke is an interactive, extensible editor for binary data. Not limited to editing basic entities such as bits and bytes, it provides a full-fledged procedural, interactive programming language designed to describe data structures and to operate on them.

GNUcap is a circuit analysis package. It offers a general purpose circuit simulator and can perform DC and transient analyses, fourier analysis and AC analysis. The engine is designed to do true mixed-mode simulation.

The Fritzing application is Electronic Design Automation (EDA) software with a low entry barrier, suited for the needs of makers and hobbyists. It offers a unique real-life "breadboard" view, and a parts library with many commonly used high-level components. Fritzing makes it very easy to communicate about circuits, as well as to turn them into PCB layouts ready for production.

GNU LibreDWG is a C library to handle DWG files. It aims to be a free replacement for the OpenDWG libraries.

Fastcap is a capacitance extraction program based on a multipole-accelerated algorithm.

Gerbv is a viewer for files in the Gerber format (RS-274X only), which is commonly used to represent printed circuit board (PCB) layouts. Gerbv lets you load several files on top of each other, do measurements on the displayed image, etc. Besides viewing Gerbers, you may also view Excellon drill files as well as pick-place files.

Zydis is a decoder and disassembler library with the following features:

• Support for all x86 and AMD64 instructions and extensions

• Optimization for high performance

• No dynamic memory allocation

• Thread-safe by design

• Smaller file-size overhead compared to other common disassembler libraries

The system call intercepting library provides a low-level interface for hooking Linux system calls in user space. This is achieved by hot-patching the machine code of the standard C library in the memory of a process.

This package provides a computer algebra system geared towards field theory. This package is mostly meant to be used by texmacs and mogan.

Libnest2D is a library and framework for the 2D bin packaging problem. It was inspired from the SVGNest Javascript library.

Udis86 is a disassembler for the x86 and x86-64 class of instruction set architectures. It consists of a C library called libudis86 which provides a clean and simple interface to decode and inspect a stream of raw binary data as disassembled instructions in a structured manner, and a command line tool called udcli that incorporates the library.

VOLK contains procedures with machine-specific optimizations for mathematical functions. It also provides a machine-independent interface to select the best such procedures to use on a given system.

SOLVESPACE is a parametric 3D CAD tool. Applications include:

• modeling 3D parts — draw with extrudes, revolves, helixes and Boolean (union / difference / intersection) operations

• modeling 2D parts — draw the part as a single section, and export DXF, PDF, SVG; use 3D assembly to verify fit

• 3D-printed parts — export the STL or other triangle mesh expected by most 3D printers

• preparing CAM data — export 2D vector art for a waterjet machine or laser cutter; or generate STEP or STL, for import into third-party CAM software for machining

• mechanism design — use the constraint solver to simulate planar or spatial linkages, with pin, ball, or slide joints

• plane and solid geometry — replace hand-solved trigonometry and spreadsheets with a live dimensioned drawing

Lcapy is a Python package for linear circuit analysis. It uses SymPy for symbolic mathematics.

Lcapy can symbolically analyse circuits described with netlists or by series/parallel combinations of components. It can also manipulate ontinuous-time and discret-time expressions.

Microcom is a minimalistic terminal program for accessing devices via a serial connection. It features connection via RS232 serial interfaces (including setting of transfer rates) as well as in telnetmode as specified in rfc2217 and a (Linux specific) CAN mode.
