Software Quotes - page 18
The software architecture of a system or a family of systems has one of the most significant impacts on the quality of an organization's enterprise architecture. While the design of software systems concentrates on satisfying the functional requirements for a system, the design of the software architecture for systems concentrates on the nonfunctional or quality requirements for systems. These quality requirements are concerns at the enterprise level. The better an organization specifies and characterizes the software architecture for its systems, the better it can characterize and manage its enterprise architecture. By explicitly defining the systems software architectures, an organization will be better able to reflect the priorities and trade-offs that are important to the organization in the software that it builds.

Ever wish you could draw a few diagrams, press a button, and have a working software system that meets your needs? Sound like magic? Perhaps, but that's a major part of the Executable UML vision. The basic idea is that you will use a CASE tool to develop detailed UML diagrams and then supplement them by specifications written in a formal language, presumably the OMG's Object Constraint Language (OCL). The basic idea behind Executable UML is that systems can be modeled at a higher level of abstraction than source code, simulated to support validation of your efforts, and then translated into efficient code. This higher-level of abstraction should help to avoid premature design, enable you to change your system as your requirements evolve, and to delay implementation decisions until the last minute.

Over the years, many companies have contributed to free software development. Some of these companies primarily developed non-free software, but the two activities were separate; thus, we could ignore their non-free products, and work with them on free software projects. Then we could honestly thank them afterward for their free software contributions, without talking about the rest of what they did.
We cannot do the same with these new companies, because they won't let us. These companies actively invite the public to lump all their activities together; they want us to regard their non-free software as favorably as we would regard a real contribution, although it is not one. They present themselves as "open source companies," hoping that we will get a warm fuzzy feeling about them, and that we will be fuzzy-minded in applying it.
This manipulative practice would be no less harmful if it were done using the term "free software."

GNU, which stands for Gnu's Not Unix, is the name for the complete Unix-compatible software system which I am writing so that I can give it away free to everyone who can use it.
[this document has a footnote mentioning that the word "free" was not used as carefully in this 1985 Manifesto as it should have been].
Richard Stallman
The GNU GPL is not Mr. Nice Guy. It says "no" to some of the things that people sometimes want to do. There are users who say that this is a bad thing - that the GPL "excludes" some proprietary software developers who "need to be brought into the free software community."
But we are not excluding them from our community; they are choosing not to enter. Their decision to make software proprietary is a decision to stay out of our community. Being in our community means joining in cooperation with us; we cannot "bring them into our community" if they don't want to join.
What we can do is offer them an inducement to join. The GNU GPL is designed to make an inducement from our existing software: "If you will make your software free, you can use this code."
Richard Stallman
A hacker is someone who enjoys playful cleverness - not necessarily with computers. The programmers in the old MIT free software community of the 60s and 70s referred to themselves as hackers. Around 1980, journalists who discovered the hacker community mistakenly took the term to mean "security breaker.”.
