The Comedi project develops open-source drivers, tools, and libraries for data acquisition.
Comedi is a collection of drivers for a variety of common data acquisition plug-in boards. The drivers are implemented as a core Linux kernel module providing common functionality and individual low-level driver modules.
Comedilib is a user-space library that provides a developer-friendly interface to Comedi devices. Included in the Comedilib distribution is documentation, configuration and calibration utilities, and demonstration programs.
Kcomedilib is a Linux kernel module (distributed with Comedi) that provides the same interface as Comedilib in kernel space, suitable for real-time tasks. It is effectively a “kernel library” for using Comedi from real-time tasks.
Features
* Integrated real-time support for most hardware
* High-level library (comedilib)
* Application-level device independence
* Requires a Linux 2.6 kernel.
I was in a mistake programming with non standard language code. I moved to free world by move to GNU/Linux. I used Borland C++ and now I use ISO/ANSI C++ with the GNU project tools (gcc, gdb, emacs, BASH, etc).
Firstly, you should read about ISO and ANSI C++, it is more commonly use ANSI C++, but ISO C++ is the correct.
It is easy, special for new programmers, that Borland C++ IDE guide you through bad programming practices. It is very easy to make a windows application with Borland C++ but is very easy to use bad and ugly programming practices too.
The principal bad programming practices usually made with C++ IDEs are:
1. Use C code instead of C++.
2. Do not use POO, or use only the classes integrated with your IDE.
2. Use IDEs’ owner libraries instead of standards.
3. Do merge the own code with GUI code.
To learn ISO/ANSI C++ from scratch or from C knowledge I recommend you to read: “C++ For Dummiesby: Stephen Randy Davis ISBN: 0764568523″, it is cheap. If you prefere you can download the Free Electronic Book: “Thinking in C++” 2nd Edition by Bruce Eckel.
One important thing to know is the STL (Standard Template Library). This library compliance with the ISO/ANSI C++. You should read about in [1].
Lets see and equivalence table between Borland C++ functions and STL functions. Note. This is only a guide, you should not use directly the “replace function” of your text application, in some case, when you had understand about, you can use it, but in others no.
Glosary:
ANSI: American National Standard Organization.
IDE: Integrated Development Environment.
ISO: International Standard Organization.
GUI: Graphical User Interface.
OOP: Object Oriented Programming.

FreeCAD is a general purpose 3D CAD modeler. The development is completely Open Source (GPL & LGPL License). FreeCAD is aimed directly at mechanical engineering and product design but also fits in a wider range of uses around engineering, such as architecture or other engineering specialties.
FreeCAD features tools similar to Catia, SolidWorks or Solid Edge, and therefore also falls into the category of MCAD, PLM, CAx and CAE. It will be a feature based parametric modeler with a modular software architecture which makes it easy to provide additional functionality without modifying the core system.
The Navy OA is a systems-design approach supported by verifiable governmental testing platforms, such as the OACE, that seeks to implement open specifications for interfaces, services and supporting formats. It enables software components to work across a range of systems and interoperate with other software components on local and remote systems.
The Navy OA promotes interaction between designers, suppliers and end users that facilitates portability. Through OA, common standards and products are employed in the areas of frameworks, middleware, resource management and operating systems, utilizing established and evolving industry standards.
OACE is a compatible set of largely standards-based COTS computing infrastructure components (hardware and software) that provides the computational framework upon which tactical and support applications are built under the guidelines of OA. The scope of OACE includes technical architecture, standards and products.
Key Open Architecture principles include:
Modular design and design disclosure
Reusable application software
Interoperable joint warfighting applications and secure information exchange
Life-cycle affordability
Encouraging competition and collaboration through development of alternative solutions and sources
The LynxOS® RTOS is the only POSIX®-conformant RTOS that is Linux ABI-compatible and it has been certified as Navy Open Architecture Computing Environment (OACE) Category 3 compliant.
An open-standards operating system such as the LynxOS RTOS must be used as the operating system in all new U.S. Navy systems, according to the Navy Open Architecture (OA)—to ensure future system interoperability and to support software reuse
Given the fierce competition in the market of the tablets where all the big companies in the sector: Apple, Google and Microsoft have an alternative in the market or in development, a Spanish company presents after Apple a cheapest option, based on free software.
On February 4 will be presented, the iFreeTablet, capping more than 20 years of research of EATCO Group at the University of Cordoba in the field of usability, ergonomics and adaptive devices as an alternative to the new Apple tablet.
iFreeTablet is one of the Orvita2 project star devices and one of the products resulting from the IPTVMunicipal Avanza project. Professor Carlos de Castro Lozano, director of the EATCO research group will make the presentation of this solution in the rectory of the University of Cordoba.
The iFreeTablet is intended as a bridge to break the digital divide between advanced users, Web 2.0 enthusiasts and those who have never used a personal computer. Advanced functionality is combined with a highly intuitive interface to achieve that goal.
The iFreeTablet, unlike the Apple tablet priced output estimated around 600 €, moves around 300-400 € and software features can evolve with the help of the free software comunity developers.
Tekkotsu is a software package for robotics aims to give you a structure on which to build, handling routine tasks so that you can focus on higher level programming.
Tekkotsu uses an object-oriented and event-passing architecture, making full use of the template and inheritance features of standard C++. It run on a variety of different robots.
We have developed this software as a means to handle tough research problems — performance and low overhead are important design considerations.
Tekkotsu is an open source, free software project that builds on several third party libraries, such as
NEWMAT (matrix operations),
libjpeg,
libpng,
libxml2, and
zlib.
Tekkotsu uses the CMVision package by Jim Bruce for color segmentation and region grouping, as well as the Aibo walk engine from Manuela Veloso’s 2002 RoboSoccer entry, CMPack’02. These latter two packages are licensed under the GPL, however Tekkotsu itself and the other libraries are licensed under the more permissive LGPL.
Technical support is provided as well as a skilled consulting service from company headquarters located in Bergamo.
Starting from version 4.0 KaeilOS is based on OpenEmbedded building system and uses the latest kernel 2.6. It supports all x86 and ARM family processors including the newer OMAP.
