Open source is a development methodology; free software is a social movement.
So, make a real effort to avoid getting sucked into all the expensive lifestyle habits of typical Americans. Because if you do that, then people with the money will dictate what you do with your life.
Programming is not a science. Programming is a craft.
Prior art is as effective as US soldiers in Iraq: They control the ground they stand on, and nothing more. I used to say Vietnam, but, well, you know...
Idiots can be defeated but they never admit it.
In terms of effect on the world, it’s very good that I’ve lived. And so I guess, if I could go back in time and prevent my birth, I wouldn’t do it. But I sure wish I hadn’t had so much pain.
I’m the last survivor of a dead culture. And I don’t really belong in the world anymore. And in some ways I feel I ought to be dead.
My favorite programming languages are Lisp and C. However, since around 1992 I have worked mainly on free software activism, which means I am too busy to do much programming. Around 2008 I stopped doing programming projects.
To be able to choose between proprietary software packages is to be able to choose your master. Freedom means not having a master. And in the area of computing, freedom means not using proprietary software.
The paradigm of competition is a race: by rewarding the winner, we encourage everyone to run faster. When capitalism really works this way, it does a good job; but its defenders are wrong in assuming it always works this way.
Copying all or parts of a program is as natural to a programmer as breathing, and as productive. It ought to be as free.
Think ‘free speech,’ not ‘free beer.’
Odious ideas are not entitled to hide from criticism behind the human shield of their believers feelings.
The idea that laws decide what is right or wrong is mistaken in general. Laws are, at their best, an attempt to achieve justice; to say that laws define justice or ethical conduct is turning things upside down.
Also, because schools must teach the spirit of goodwill, the habit of helping others around you, every class should have this rule: students, if you bring software to class you may not keep it for yourself.
Sharing knowledge is the most fundamental act of friendship. Because it is a way you can give something without losing something.
Once GNU is written, everyone will be able to obtain good system software free, just like air.
Without absolute certainty, what do we do? We do the best we can. Injustice is happening now; suffering is happening now. We have choices to make now. To insist on absolute certainty before starting to apply ethics to life decisions is a way of choosing to be amoral.
I consider that the Golden Rule requires that if I like a program I must share it with other people who like it. Software sellers want to divide the users and conquer them, making each user agree not to share with others. I refuse to break solidarity with other users in this way.
The principal lesson of Emacs is that a language for extensions should not be a mere “extension language”. It should be a real programming language, designed for writing and maintaining substantial programs. Because people will want to do that!
A commune is where people join together to share their lack of wealth.
