The discipline of programming is most like sorcery. Both use precise language to instruct inanimate objects to do our bidding. Small mistakes in programs or spells can lead to completely unforseen behavior: e.g., see the story, "The Sorcerer's Apprentice". Neither study is easy: "...her [Galinda's] early appetite for sorcery had waned once she'd heard what a grind it was to learn spells and, worse, to understand them." from the book "Wicked" by G. Maguire.
In Buddhism, both learning and practice are extremely important, and they must go hand in hand. Without knowledge, just to rely on faith, faith, and more faith is good but not sufficient. So the intellectual part must definitely be present. At the same time, strictly intellectual development without faith and practice, is also of no use. It is necessary to combine knowledge born from study with sincere practice in our daily lives. These two must go together.
When certain concepts of TeX are introduced informally, general rules will be stated; afterwards you will find that the rules aren't strictly true. In general, the later chapters contain more reliable information than the earlier ones do. The author feels that this technique of deliberate lying will actually make it easier for you to learn the ideas. Once you understand a simple but false rule, it will not be hard to supplement that rule with its exceptions.
Be careful what you say. It comes true. It comes true. I had to leave home in order to see the world logically, logic the new way of seeing. I learned to think that mysteries are for explanation. I enjoy the simplicity. Concrete pours out of my mouth to cover the forests with freeways and sidewalks. Give me plastics, periodical tables, TV dinners with vegetables no more complex than peas mixed with diced carrots. Shine floodlights into dark corners: no ghosts.
Our intellectual powers are rather geared to master static relations and that our powers to visualize processes evolving in time are relatively poorly developed. For that reason we should do (as wise programmers aware of our limitations) our utmost to shorten the conceptual gap between the static program and the dynamic process, to make the correspondence between the program (spread out in text space) and the process (spread out in time) as trivial as possible.
They say for every light on Broadway there is a broken heart, an unrealized dream. And that’s the same in any profession. So you have to want it more than anyone else, and you have to be your own champion, be your own superstar, blaze your own path, say yes to opportunity, follow your instincts, be eager, and passionate, keep learning, nurture your real, lasting relationships, don’t be a jerk, and free your imagination so you can become all that you want to be.
A man only begins to be a man when he ceases to whine and revile, and commences to search for the hidden justice which regulates his life. And he adapts his mind to that regulating factor, he ceases to accuse others as the cause of his condition, and builds himself up in strong and noble thoughts; ceases to kick against circumstances, but begins to use them as aids to his more rapid progress, and as a means of the hidden powers and possibilities within himself.
EMACS could not have been reached by a process of careful design, because such processes arrive only at goals which are visible at the outset, and whose desirability is established on the bottom line at the outset. Neither I nor anyone else visualized an extensible editor until I had made one, nor appreciated its value until he had experienced it. EMACS exists because I felt free to make individually useful small improvements on a path whose end was not in sight.
Beauty is more important in computing than anywhere else in technology because software is so complicated. Beauty is the ultimate defense against complexity. ... The geniuses of the computer field, on the the other hand, are the people with the keenest aesthetic senses, the ones who are capable of creating beauty. Beauty is decisive at every level: the most important interfaces, the most important programming languages, the winning algorithms are the beautiful ones.
Life . . . is a joyful expression of love, praise and thanksgiving instead of a hopeless struggle which eventually ends in death. Giving thanks in every circumstance, we forego the logic and reason which asks, "Why me?" and open our hearts and learn to trust. Every obstacle becomes an occasion for rejoicing. We put love at the center of our universe and we are lifted beyond the world of limitation, doubt, and fear into the realm of love, hope, and eternal happiness.
To be free one needs constant and unrelenting vigilance over one's weaknesses. A vigilance which requires a moral energy most of us are incapable of manufacturing. We relax back into the moulds of habit. They are secure, they bind us and keep us contained at the expense of freedom. To break the moulds, to be heedless of the seductions of security is an impossible struggle, but one of the few that count. To be free is to learn, to test yourself constantly, to gamble.
My key to living an inspired life involves Embracing my history, Understanding the function of expectations and gently learning to have none; Recognizing the power of attentive and conscious choices. In all circumstances I acknowledge this, IN ALL THINGS AND ALL WAYS, I HAVE CHOICE. My choice resides in my perspective. While I certainly do not control climate and markets and roadways and others, I do control myself and my response to all those circumstances. I do indeed.
The advances of biology during the past 20 years have been breathtaking, particularly in cracking the mystery of heredity. Nevertheless, the greatest and most difficult problems still lie ahead. The discoveries of the 1970's about the chemical roots of memory in nerve cells or the basis of learning, about the complex behavior of man and animals, the nature of growth, development, disease and aging will be at least as fundamental and spectacular as those of the recent past.
When I heard the learn’d astronomer; When the proofs, the figures, were ranged in columns before me; When I was shown the charts and the diagrams, to add, divide, and measure them; When I, sitting, heard the astronomer, where he lectured with much applause in the lecture-room, How soon, unaccountable, I became tired and sick; Till rising and gliding out, I wander’d off by myself, In the mystical moist night-air, and from time to time, Look’d up in perfect silence at the stars.
Any piece of knowledge which the pupil has himself acquired- any problem which he has himself solved, becomes, by virtue of the conquest, much more thoroughly his than it could else be. The preliminary activity of mind which his success implies, the concentration of thought necessary to it, and the excitement consequent on his triumph, conspire to register the facts in his memory in a way that no mere information heard from a teacher, or read in a schoolbook, can be registered.
One is constantly reminded of the infinite lavishness and fertility of Nature-inexhaustible abundance amid what seems enormous waste. And yet when we look into any of her operations that lie within reach of our minds, we learn that no particle of her material is wasted or worn out. It is eternally flowing from use to use, beauty to yet higher beauty; and we soon cease to lament waste and death, and rather rejoice and exult in the imperishable, unspendable wealth of the universe.
Instruction, and advice, and commands will profit little, unless they are backed up by the pattern of your own life. Your children will never believe you are in earnest, and really wish them to obey you, so long as your actions contradict your counsel... Think not your children will practise what they do not see you do. You are their model picture, and they will copy what you are... will seldom learn habits which they see you despise, or walk in paths in which you do not walk yourself.
I learned a lot of different things from different schools. MIT is a very good place…. It has developed for itself a spirit, so that every member of the whole place thinks that it’s the most wonderful place in the world—it’s the center, somehow, of scientific and technological development in the United States, if not the world … and while you don’t get a good sense of proportion there, you do get an excellent sense of being with it and in it, and having motivation and desire to keep on
Complexity has and will maintain a strong fascination for many people. It is true that we live in a complex world and strive to solve inherently complex problems, which often do require complex mechanisms. However, this should not diminish our desire for elegant solutions, which convince by their clarity and effectiveness. Simple, elegant solutions are more effective, but they are harder to find than complex ones, and they require more time, which we too often believe to be unaffordable
Motive is also important in our quest for knowledge and in the questioning that accompanies it. In commenting on our duty to educate for eternity, Eugene England writes: Teaching or learning - with the Spirit of God simply means (though it is not simple) that we are doing so with an eye single to eternal, not worldly, values, with an eye single to lasting development of the mind and spirit and to useful service to others, especially to aid in their lasting development of mind and spirit.
...methods are more important than facts. The educational value of a problem given to a student depends mostly on how often the thought processes that are invoked to solve it will be helpful in later situations. It has little to do with how useful the answer to the problem may be. On the other hand, a good problem must also motivate the students; they should be interested in seeing the answer. Since students differ so greatly, I cannot expect everyone to like the problems that please me.
If they think they are doing something new, they ought to do what I do every day - spend at least two hours every day listening to Johann Sebastian Bach and, man, it's all there. If they want to improvise around a theme,which is the essence of jazz, they should learn from the master. He never wastes a note, and he knows where every note is going and when to bring it back. Some of these cats go way out and forget where they began or what they started to do. Bach will clear it up for them.
We're different, we're the same. You thought you'd never find a word to say to a woman who didn't fly airplanes. I couldn't imagine myself spending time with a man who didn't love music. Could it be it's not as important to be alike as it is to be curious? Because we're different, we can have the fun of exchanging worlds, giving our loves and excitements to each other. You can learn music, I can learn flying. And that's only the beginning. I think it would go on for us as long as we live.
It takes more time and effort and delicacy to learn the silence of a people than to learn its sounds. Some people have a special gift for this. Perhaps this explains why some missionaries, notwithstanding their efforts, never come to speak properly, to communicate delicately through silences. Although they "speak with the accent of natives" they remain forever thousands of miles away. The learning of the grammar of silence is an art much more difficult to learn than the grammar of sounds.
There are for man only two principles available for a mental grasp of reality, namely, those of teleology and causality. What cannot be brought under either of these categories is absolutely hidden to the human mind. An event not open to an interpretation by one of these two principles is for man inconceivable and mysterious. Change can be conceived as the outcome either of the operation of mechanistic causality or of purposeful behavior; for the human mind there is no third way available.
Love of goodness without love of learning degenerates into simple-mindedness. Love of knowledge without love of learning degenerates into utter lack of principle. Love of faithfulness without love of learning degenerates into injurious disregard of consequences. Love of uprightness without love of learning degenerates into harshness. Love of courage without love of learning degenerates into insubordination. Love of strong character without love of learning degenerates into mere recklessness.
Most people have learned to live in the moment. The argument goes that if the past has uncertain effect on the present, there is no need to dwell on the past. And if the present has little effect on the future, present actions need not be weighed for their consequence. Rather, each act is an island in time, to be judged on its own. ... It is a world of impulse. It is a world of sincerity. It is a world in which every word spoken speaks just to that moment, every glance given has only one meaning.
It is by discourse that men associate, and words are imposed according to the apprehension of the vulgar. And therefore the ill and unfit choice of words wonderfully obsesses the understanding. Nor do the definitions or explanations wherewith in some things learned men are wont to guard and defend themselves, by any means set the matter right. But words plainly force and overrule the understanding, and throw all into confusion, and lead men away into innumerable and inane controversies and fancies.
There is a race between the increasing complexity of the systems we build and our ability to develop intellectual tools for understanding their complexity. If the race is won by our tools, then systems will eventually become easier to use and more reliable. If not, they will continue to become harder to use and less reliable for all but a relatively small set of common tasks. Given how hard thinking is, if those intellectual tools are to succeed, they will have to substitute calculation for thought.
As soon as the circumstances of an experiment are well known, we stop gathering statistics. ... The effect will occur always without exception, because the cause of the phenomena is accurately defined. Only when a phenomenon includes conditions as yet undefined,Only when a phenomenon includes conditions as yet undefined, can we compile statistics. ... we must learn therefore that we compile statistics only when we cannot possibly help it; for in my opinion, statistics can never yield scientific truth.
I immediately cotton on to the fact that intelligence thus lightly used, and one-upmanshipishly displayed, is a birthmark giving me a two-coloured face, is a goitre, a hump on the back, webbed toes, and makes me stink like the night-man. Once again I learn what I knew on my very first day at Kensington School, and have carelessly forgotten, that it is more intelligent to appear less intelligent. I henceforth rein myself in, and publicly give back only what I have been given - fifty-six for seven- eights.
It is not knowledge, but the act of learning, not possession but the act of getting there, which grants the greatest enjoyment. When I have clarified and exhausted a subject, then I turn away from it, in order to go into darkness again; the never-satisfied man is so strange if he has completed a structure, then it is not in order to dwell in it peacefully,but in order to begin another. I imagine the world conqueror must feel thus, who, after one kingdom is scarcely conquered, stretches out his arms for others.
Knowledge about yourself binds, weighs, ties you down; there is no freedom to move, and you act and move within the limits of thatknowledge. Learning about yourself is never the same as accumulating knowledge about yourself. Learning is active present and knowledge is the past; if you are learning to accumulate, it ceases to be learning; knowledge is static, more can be added to it or taken away from it, but learning is active, nothing can be added or taken away from it for there is no accumulation at any time.
The important point is that the cost of adding a feature isn't just the time it takes to code it. The cost also includes the addition of an obstacle to future expansion. Sure, any given feature list can be implemented, given enough coding time. But in addition to coming out late, you will usually wind up with a codebase that is so fragile that new ideas that should be dead-simple wind up taking longer and longer to work into the tangled existing web. The trick is to pick the features that don't fight each other.
Barry Jones once said that Australia is the only country where the word 'academic' is a pejorative. The academic sector has a vibrant and practical role to play in this complex world of ours. Higher education and research are worthy of your much closer attention. Yes, we can be and should be the clever country. Our progress can be within the highest ethical and moral framework. But this will only happen if we place appropriate emphasis on education, research and innovation within a truly international framework.
The best results are achieved by using the right amount of effort in the right place at the right time. And this right amount is usually less than we think we need. In other words, the less unnecessary effort you put into learning, the more successful you'll be... the key to faster learning is to use appropriate effort. Greater effort can exacerbate faulty patterns of action. Doing the wrong thing with more intensity rarely improves the situation. Learning something new often requires us to unlearn something old.
When building a complex system, having crackerjack programmers (who can make any design work, even a bad one) can be a liability. The result, after lots of effort, is a working system that cannot be easily maintained or upgraded. Good -but not great- programmers would fail early, causing a realization that the system must be redesigned, and then reimplemented. The extra cost is paid once, early in the system's cycle (when it is cheap), instead of repeatedly paid late in the system's cycle (when it is more expensive).
What I must do is all that concerns me, not what people think. This rule,equally arduous in actual and intellectual life, may serve for the whole distinction between greatness and meanness. It is the harder, because you will always find those who think they know what is your duty better than you know it. It is easy in the world to live after the world's opinion; it is easy in solitude to live after our own; but the great man is he who in the midst of the crowd keeps with perfect sweetness the independence of solitude.
The Commonwealth of Learning is not at this time without Master-Builders, whose mighty Designs, in advancing the Sciences, will leave lasting Monuments to the Admiration of Posterity; But every one must not hope to be a Boyle, or a Sydenham; and in an Age that produces such Masters, as the Great-Huygenius, and the incomparable Mr. Newton, with some other of that Strain; 'tis Ambition enough to be employed as an Under-Labourer in clearing Ground a little, and removing some of the Rubbish, that lies in the way to Knowledge.
We thus begin to see that the institutionalized practice of citations and references in the sphere of learning is not a trivial matter. While many a general reader-that is, the lay reader located outside the domain of science and scholarship-may regard the lowly footnote or the remote endnote or the bibliographic parenthesis as a dispensable nuisance, it can be argued that these are in truth central to the incentive system and an underlying sense of distributive justice that do much to energize the advancement of knowledge.
Another effective [debugging] technique is to explain your code to someone else. This will often cause you to explain the bug to yourself. Sometimes it takes no more than a few sentences, followed by an embarrassed "Never mind, I see what's wrong. Sorry to bother you." This works remarkably well; you can even use non-programmers as listeners. One university computer center kept a teddy bear near the help desk. Students with mysterious bugs were required to explain them to the bear before they could speak to a human counselor.
At first I hoped that such a technically unsound project would collapse but I soon realized it was doomed to success. Almost anything in software can be implemented, sold, and even used given enough determination. There is nothing a mere scientist can say that will stand against the flood of a hundred million dollars. But there is one quality that cannot be purchased in this way - and that is reliability. The price of reliability is the pursuit of the utmost simplicity. It is a price which the very rich find most hard to pay.
Consider prejudice. Once a person begins to accept a stereotype of a particular group, that "thought" becomes an active agent, "participating" in shaping how he or she interacts with another person who falls in that stereotyped class. In turn, the tone of their interaction influences the other person's behaviour. The prejudiced person can't see how his prejudice shapes what he "sees" and how he acts. In some sense, if he did, he would no longer be prejudiced. To operate, the "thought" of prejudice must remain hidden to its holder
One of the most difficult problems of our age is that leaders, and perhaps academics as well, cannot readily admit that things are out of control and that we do not know what to do. We have too much information, limited cognitive abilities to think in systemic terms and an unwillingness to appear to be in control and to have solutions for our problems. We are afraid that if we admit to our confusion, we will make our followers and students anxious and disillusioned. We know we must learn how to learn, but we are afraid to admit it.
We do not need to invent sustainable human communities. We can learn from societies that have lived sustainably for centuries. We can also model communities after nature's ecosystems, which are sustainable communities of plants, animals, and microorganisms. Since the outstanding characteristic of the biosphere is its inherent ability to sustain life, a sustainable human community must be designed in such a manner that its technologies and social institutions honor, support, and cooperate with nature's inherent ability to sustain life.
There is plenty of room left for exact experiment in art, and the gate has been opened for some time. What had been accomplished in music by the end of the eighteenth century has only begun in the fine arts. Mathematics and physics have given us a clue in the form of rules to be strictly observed or departed from, as the case may be. Here salutary discipline is come to grips first of all with the function of forms, and not with form as the final result … in this way we learn how to look beyond the surface and get to the root of things.
A learned parson, rusting in his cell at Oxford or Cambridge, will reason admirably well upon the nature of man; will profoundly analyze the head, the heart, the reason, the will, the passions, the senses, the sentiments, and all those subdivisions of we know not what ; and yet, unfortunately, he knows nothing of man... He views man as he does colours in Sir Isaac Newton's prism, where only the capital ones are seen; but an experienced dyer knows all their various shades and gradations, together with the result of their several mixtures.
Science only means knowledge; and for [Greek] ancients it did only mean knowledge. Thus the favorite science of the Greeks was Astronomy, because it was as abstract as Algebra. ... We may say that the great Greek ideal was to have no use for useful things. The Slave was he who learned useful things; the Freeman was he who learned useless things. This still remains the ideal of many noble men of science, in the sense they do desire truth as the great Greeks desired it; and their attitude is an external protest against vulgarity of utilitarianism.
I'm focussing on what I haven't attained, not what I have. A lot has come to me early. I don't want to get consumed with that. Winners live in the present tense. People who come up short are consumed with future or past. I want to be living in the now. My goal is to play one full game in the now, but I haven't even gotten past the first inning yet. I start thinking about where my mom is or if my dogs have been fed. The average human has 2,000 thoughts a day. The really accomplished have 1,500 because you can focus longer. I need to learn how to focus longer.
I believe that we learn by practice. Whether it means to learn to dance by practicing dancing or to learn to live by practicing living, the principles are the same. In each, it is the performance of a dedicated precise set of acts, physical or intellectual, from which comes shape of achievement, a sense of one's being, a satisfaction of spirit. One becomes, in some area, an athlete of God. Practice means to perform, over and over again in the face of all obstacles, some act of vision, of faith, of desire. Practice is a means of inviting the perfection desired.
