A Quote by Edsger Dijkstra
If you want more effective programmers, you will discover that they should not waste their time debugging, they should not introduce the bugs to start with.

Programmers waste enormous amounts of time thinking about, or worrying about, the speed of noncritical parts of their programs, and these attempts at efficiency actually have a strong negative impact when debugging and maintenance are considered. We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil. Yet we should not pass up our opportunities in that critical 3%.
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.
We hope that there will be nothing that conflicts with anybody's religion or faith. We would never say a person's religion is not effective. We say, 'Would you be interested in something more effective?' We always put things in an optimistic, progressive perspective. 'Do you want to make your prayers more effective? Not that they are not effective, but do you want to help them become more effective?'
I think we should stop asking people in their 20s what they 'want to do' and start asking them what they don't want to do. Instead of asking students to 'declare their major' we should ask students to 'list what they will do anything to avoid.' It just makes a lot more sense.
When you use Google, do you get more than one answer? Of course you do. Well, that's a bug. We have more bugs per second in the world. We should be able to give you the right answer just once. We should know what you meant.
There are a couple of people in the world who can really program in C or FØRTRAN. They write more code in less time than it takes for other programmers. Most programmers aren't that good. The problem is that those few programmers who crank out code aren't interested in maintaining it.
Gentlemen should not waste their time on trivial games -- they should play go[3]
Waste no more time arguing what a good man should be. Be one.
I believe when you say you're going to start a race at 2 p.m. then you should stick to that and start the race at 2 p.m. There's no maybe, could be or should be. You start the race on time. It's very simple.
Major league baseball players and owners should meet immediately to enact the standards that apply to the minor leagues, and if they don't, I will have to introduce legislation that says professional sports will have minimum standards for testing. I'll give them until January, and then I'll introduce legislation.
Waste no more time arguing about what a good man should be. Be one.
Paper should be edible, nutritious. Inks used for printing or writing should have delicious flavors. Magazines or newspapers read at breakfast should be eaten for lunch. Instead of throwing one's mail in the waste-basket, it should be saved for the dinner guests.
If you want to be an actor, you should just get out there and do it. I don't go for the approach of first getting photos and an agent. I think you should start with the work, and the other stuff will follow. As with 'opportunity knocks,' you have to be ready.
Our time on this earth is sacred, and we should celebrate every moment.
The importance of this has been completely forgotten: even religious holidays have been transformed into opportunities to go to the beach or the park or skiing. There are no more rituals. Ordinary actions can no longer be transformed into manifestations of the sacred. We cook and complain that it's a waste of time, when we should be pouring our love into making that food. We work and believe it's a divine curse, when we should be using our skills to bring pleasure and to spread the energy of the Mother.
Vexation of spirit is a waste of time Negative thinking, don't you waste your thoughts Verbal conflict is a waste of word Physical conflict is a waste of flesh People will always be who they want And that's what really makes the world go round Unconditional love is scarce.
All should be taught that the highest ambition is to be happy, and to add to the well-being of others; that place and power are not necessary to success; that the desire to acquire great wealth is a kind of insanity. They should be taught that it is a waste of energy, a waste of thought, a waste of life, to acquire what you do not need and what you do not really use for the benefit of yourself or others.
