Engineers build Raspberry Pi supercomputer

(Phys.org)—Computational Engineers at the University of Southampton have built a supercomputer from 64 Raspberry Pi computers and Lego.

New data reveals climate change might be more rapid than predicted

About 30 massive, intricate computer networks serve the scientists who stand at the forefront of climate change research. Each network runs a software program comprised of millions of lines of code. These programs are computational ...

Google Go gets going (w/ Video)

(PhysOrg.com) -- Google has introduced its new experimental programming language Go, which aims to combine speedy application development through simplified coding with high-speed program execution.

Visualize sounds and tune instruments precisely and intuitively

A novel process for analyzing and visualizing sound has been designed by the Laboratoire Sciences et Technologies de la Musique et du Son (CNRS/IRCAM/French Ministry of Culture and Communication/UPMC). The SnailAnalyser-Tuner ...

Physicists describe new type of aurora

For millennia, humans in the high latitudes have been enthralled by auroras—the northern and southern lights. Yet even after all that time, it appears the ethereal, dancing ribbons of light above Earth still hold some secrets.

An oracle for object-oriented programmers

In the last 40 years, the major innovation in software engineering has been the development of what are called object-oriented programming languages. “Objects” are, effectively, repositories for the computational ...

Endless original, copyright-free music

A group of researchers from the University of Granada has developed Inmamusys, a software program that can create music in response to emotions that arise in the listener. By using Artificial Intelligence techniques, the ...

Computer program

Computer programs (also software programs, or just programs) are instructions for a computer. A computer requires programs to function, typically executing the program's instructions in a central processor. The program has an executable form that the computer can use directly to execute the instructions. The same program in its human-readable source code form, from which executable programs are derived (e.g., compiled), enables a programmer to study and develop the algorithm.

Computer source code is often written by professional computer programmers. Source code is written in a programming language that usually follows one of two main paradigms: imperative or declarative programming. Source code may be converted into an executable file (sometimes called an executable program or a binary) by a compiler. Alternatively, computer programs may be executed by a central processing unit with the aid of an interpreter, or may be embedded directly into hardware (in which case it is more widely known under the term 'firmware', as something 'between' software and hardware).

Computer programs may be categorized along functional lines: system software and application software. And many computer programs may run simultaneously on a single computer, a process known as multitasking.
