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)
Some may say Ruby is a bad rip-off of Lisp or Smalltalk, and I admit that. But it is nicer to ordinary people. -- Matz, LL2
What do Americans look for in a car? I've heard many answers when I've asked this question. The answers include excellent safety ratings, great gas mileage, handling, and cornering ability, among others. I don't believe any of these. That's because the first principle of the Culture Code is that the only effective way to understand what people truly mean is to ignore what they say. This is not to suggest that people intentionally lie or misrepresent themselves. What it means is that, when asked direct questions about their interests and preferences, people tend to give answers they believe the questioner wants to hear. Again, this is not because they intend to mislead. It is because people respond to these questions with their cortexes, the parts of their brains that control intelligence rather than emotion or instinct. They ponder a question, they process a question, and when they deliver an answer, it is the product of deliberation. They believe they are telling the truth. A lie detector would confirm this. In most cases, however, they aren't saying what they mean. -- The culture code.
All non-trivial abstractions, to some degree, are leaky. -- Joel Spolsky (The Law of Leaky Abstractions)
You think you know when you learn, are more sure when you can write, even more when you can teach, but certain when you can program. -- Alan J. Perlis (Epigrams in programming)
If there is a will, there is a way. -- unknown
