The venerable master Qc Na was walking with his student, Anton. Hoping to prompt the master into a discussion, Anton said "Master, I have heard that objects are a very good thing - is this true?" Qc Na looked pityingly at his student and replied, "Foolish pupil - objects are merely a poor man's closures." Chastised, Anton took his leave from his master and returned to his cell, intent on studying closures. He carefully read the entire "Lambda: The Ultimate..." series of papers and its cousins, and implemented a small Scheme interpreter with a closure-based object system. He learned much, and looked forward to informing his master of his progress. On his next walk with Qc Na, Anton attempted to impress his master by saying "Master, I have diligently studied the matter, and now understand that objects are truly a poor man's closures." Qc Na responded by hitting Anton with his stick, saying "When will you learn? Closures are a poor man's object." At that moment, Anton became enlightened. -- Anton van Straaten (Na = Norman Adams, Qa = Christian Queinnec)
Let me try to get this straight: Lisp is a language for describing algorithms. This was JohnMcCarthy's original purpose, anyway: to build something more convenient than a Turing machine. Lisp is not about file, socket or GUI programming - Lisp is about expressive power. (For example, you can design multiple object systems for Lisp, in Lisp. Or implement the now-fashionable AOP. Or do arbitrary transformations on parsed source code.) If you don't value expressive power, Lisp ain't for you. I, personally, would prefer Lisp to not become mainstream: this would necessarily involve a dumbing down. -- VladimirSlepnev
The only constant in the world of hi-tech is change. -- Mark Ward
Being a programmer is the same way. The only way to be a good programmer is to write code. When you realize you haven't been writing much code lately, and it seems like all you do is brag about code you wrote in the past, and people start looking at you funny while you're shooting your mouth off, realize it's because they know. They might not even know they know, but they know. So, yes, doing what you love brings success, and by all means, throw yourself a nice big party, buy yourself a nice car, soak up the adulation of an adoring crowd. Then shut the fuck up and get back to work. -- Sincerity Theory
C++ is history repeated as tragedy. Java is history repeated as farce. -- Scott McKay
Luck is where preparation meets opportunity. -- Randy Pausch
When one door of happiness closes, another opens, but often we look so long at the closed door that we do not see the one that has been opened for us. –Helen Keller
You can’t connect the dots looking forward; you can only connect them looking backwards. So you have to trust that the dots will somehow connect in your future. You have to trust in something - your gut, destiny, life, karma, whatever. This approach has never let me down, and it has made all the difference in my life. ~Steve Jobs
We can easily forgive a child who is afraid of the dark; the real tragedy of life is when men are afraid of the light. –Plato
The two most important days in your life are the day you are born and the day you find out why. –Mark Twain
