XFOIL is an interactive program for the design and analysis of subsonic isolated airfoils. It consists of a collection of menu-driven routines which perform various useful functions such as:

• Viscous (or inviscid) analysis of an existing airfoil

• Airfoil design and redesign by interactive modification of surface speed distributions

• Airfoil redesign by interactive modification of geometric parameters

• Blending of airfoils

• Writing and reading of airfoil coordinates and polar save files

• Plotting of geometry, pressure distributions, and multiple polars

Iaito is the official graphical interface for radare2, a libre reverse engineering framework. Iaito focuses on simplicity, parity with commands, features, and keybindings.

Inspekt3d is a lightweight 3D viewer for Libfive written in Guile Scheme. The viewer can be used interactively with a REPL (for example Geiser in Emacs).

Meep is a finite-difference time-domain (FDTD) simulation software package developed at MIT to model electromagnetic systems.

This package includes simulation models for an induction motor, a synchronous reluctance motor, and a permanent-magnet synchronous motor. The motor models are simulated in the continuous-time domain while the control algorithms run in discrete time. The default solver is the explicit Runge-Kutta method of order 5(4) from scipy.integrate.solve_ivp.

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.

mbpoll is a command line utility to communicate with ModBus slave (RTU or TCP).

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.

This package provides a C++ library for handling of multiple co-processes in cadabra.

Capstone is a lightweight multi-platform, multi-architecture disassembly framework. Capstone can disassemble machine code for many supported architectures such as x86, x86_64, arm, arm64, mips, ppc, sparc, sysz and xcore. It provides bindings for Python, Java, OCaml and more.

GrblHAL CNC command sender, autoleveler, g-code editor, digitizer, CAM and swiss army knife for all your CNC needs. The sender is robust and fast able to work nicely with old or slow hardware.

QElectroTech, or QET in short, is a desktop application to create diagrams and schematics. The software is primarily intended to create electrical documentation but it can also be used to draw any kinds of diagrams, such as those made in pneumatics, hydraulics, process industries, electronics, and others.

GNU PCB is an interactive tool for editing printed circuit board layouts. It features a rats-nest implementation, schematic/netlist import, and design rule checking. It also includes an autorouter and a trace optimizer; and it can produce photorealistic and design review images.

LinSmith is a Smith Charting program, mainly designed for educational use. As such, there is an emphasis on capabilities that improve the 'showing the effect of'-style of operation.

Rizin is a reverse engineering framework and a set of small command-line utilities, providing a complete binary analysis experience with features like disassembler, hexadecimal editor, emulation, binary inspection, debugger, and more.

ASCO brings circuit optimization capabilities to existing SPICE simulators using a high-performance parallel differential evolution (DE) optimization algorithm.

Lib3ds is a toolkit for handling the 3DS format for 3D model files. Its main goal is to simplify the creation of 3DS import and export filters.

This package provides an OPC UA / IEC 62541 client and server for Python and pypy3.

Lepton EDA ia an electronic design automation (EDA) tool set forked from gEDA/gaf in late 2016. EDA tools are used for electrical circuit design, schematic capture, simulation, prototyping, and production. Lepton EDA includes tools for schematic capture, attribute management, bill of materials (BOM) generation, netlisting into over 20 netlist formats, analog and digital simulation, and printed circuit board (PCB) layout, and many other features.

ADMS is a code generator that converts electrical compact device models specified in high-level description language into ready-to-compile C code for the API of spice simulators. Based on transformations specified in XML language, ADMS transforms Verilog-AMS code into other target languages.

Lib3MF is a C++ implementation of the 3D Manufacturing Format (3MF) file standard. It offers a way to integrate 3MF reading and writing capabilities, as well as conversion and validation tools for input and output data. The specification can be downloaded at http://3mf.io/specification/.

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.

The purpose of the MED module is to provide a standard for storing and recovering computer data associated to numerical meshes and fields, and to facilitate the exchange between codes and solvers.

The persistent data storage is based upon HDF format (like CGNS, a standard developed by Boeing and NASA in the area of Computational Fluid Dynamic).

MED also provides structures to hold data on meshes and fields. These structures are exchanged between solvers, hide the communication level (CORBA or MPI), and offer persistence (read/write in .med files).

The main benefit of a common exchange format is reduced complexity of code coupling. It also allows sharing such high level functionalities as computation of nodal connectivity of sub-elements (faces and edges), arithmetic operations on fields, entity location functionalities, and interpolation toolkit.
