Richard Stallman, Software libre y Licencia GNU: ética, inteligencia y comunidad

Como colofón al III congreso Hispalinux, el día 12 de noviembre, en el campus de Leganés de la universidad Carlos III de Madrid, se celebró la extraordinaria conferencia El movimiento de software libre y el desarrollo del sistema operativo libre GNU/Linux a cargo de Richard Stallman, conocido como RMS, a la sazón el creador y más importante impulsor de ambas realidades.

Practical real-time computing system for biomedical experiment interface.

Many biomedical experiments require a precisely timed real-time (RT) computer interface. Because commonly used desktop operating systems are inherently non-real-time, real-time laboratory computer systems are often based on outdated DOS software or expensive proprietary real-time operating systems. Here we discuss a real-time computing system, based on the free RT-LINUX operating system, which we have developed for adaptive pacing control in a clinical cardiac electrophysiology laboratory. This powerful, flexible, and inexpensive system demonstrates that RT-LINUX is well suited for real-time biomedical experiment interface.

Linux. A Free Operating System for Computer Users.

Linux. A Free Operating System for Computer Users.

From Army of Hackers, an Upstart Operating System

COMPUTER SCIENCEThanks to a massive and largely unpaid effort by programmers around the world, a free computer operating system called Linux, a simpler-to-use variant of UNIX, is currently poised to compete with Microsoft's Windows. Already, Linux is the operating system of choice for Internet servers, the computers that route Internet traffic and host sites on the World Wide Web, and its use is growing rapidly for small-sized servers on local area networks. It also serves as the operating system on a cut-rate supercomputer at Los Alamos National Laboratory that has been running for many months now without crashing, reliability that is almost unheard of in the supercomputer world.

A flexible graphical user interface for embedding heterogeneous neural network simulators

A graphical user interface (GUI) for heterogeneous neural network simulators proposed in this article is intended to be of use both for the novice and for the experienced neural network user. For the novice, it provides an easy-to-use neural network simulation package that insulates the user from the requirements of knowing the simulator implementation details or the configuration file syntax. For the experienced neural network professional it provides an interface that is easily extensible to include any additional neural network simulator in its binary form. To satisfy both academic and personal computer environments, the GUI has been developed by using the free TCL/TK software package, available on workstations running Unix and on PCs running the free Linux operating system. Although the GUI and the embedded simulators have been successfully tested both in neural network research and training programs, a more extensive testing in undergraduate and graduate level classes is in progress.

The Linux operating system

The enormous consumer market for IBM PCs and compatibles has made them affordable. Now, with a free operating system called Linux, these inexpensive machines can be converted into powerful workstations for teaching, research and software development. For professionals who use Unix-based workstations at work, Linux permits virtually identical working environments on their personal home machines. For cost-conscious educational institutions-especially in developing nations-Linux can create world-class computing environments from inexpensive, easily maintained PC clones. And for university students-especially in science and engineering-Linux provides an essentially cost-free path into Unix and X Windows.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
