Open source programs are made available with their source code, or basic underlying instructions, available for anyone to read, modify or copy.
The term stands for both an iconoclastic philosophy and a software development model: software is distributed free and its "source code," or underlying instructions, are published openly so that other programmers can study, share and modify the author's work.
The 47-year-old Mr. O'Reilly, who studied classics as an undergraduate at Harvard, is also an outspoken advocate of open-source software, which is distributed free and whose underlying instructions, or source code, are published openly rather than guarded as a company's property.
In these days, every new added hardware feature must not change the underlying Instruction Set Architecture (ISA), in order to avoid adaptation or recompilation of existing code.
This is a decentralised form of production in which the underlying programming instructions, or "source code", for a given piece of software are made freely available.
In China, South Korea, India, Brazil and other countries, governments are promoting the use of such software which, unlike the proprietary kind, allows users to inspect, modify and freely redistribute its underlying programming instructions.
Open source code -- free distribution of the underlying program instructions for software, so that other programmers can pursue further development -- is one of the basic principles behind the open or free software movement that Mozilla and, even more important, Linux, came to represent.
The basis for the performance of ACES III resides in the underlying super instruction architecture (SIA), which is a framework for parallel programming.
The firm hires the most driven programmers, pays them a lot in share options, works them hard and then sells the product in a form that customers can use, but not change (because it comes without the "source code", the set of computer instructions underlying a program).
This algorithm converts the latency bounded computations to throughput oriented ones, and maximizes the utilization of the pipelined hardware that underlies the instruction, achieving speedup of a factor of almost 3.
It refers to any mechanism that underlies the instruction to either imagine-oneself in the situation of the other and to imagine how one would then feel or to imagine-the-other in his situation and to imagine how he would feel (Stotland 1969, 292); or what Hoffman calls self-focused and other-focused role-taking (Hoffman 2000).
