Beware of bugs in the above code; I have only proved it correct, not tried it. — © Donald Knuth
Beware of bugs in the above code; I have only proved it correct, not tried it.
The real value of tests is not that they detect bugs in the code but that they detect inadequacies in the methods, concentration, and skills of those who design and produce the code.
After my son died, I went to a psychiatrist. He proved - or I proved - that Sigmund Freud was correct when he said that the Irish are impervious to psychoanalysis.
It's true, I had hacked into a lot of companies, and took copies of the source code to analyze it for security bugs. If I could locate security bugs, I could become better at hacking into their systems. It was all towards becoming a better hacker.
Beware, my body and my soul, beware above all of crossing your arms and assuming the sterile attitude of the spectator, for life is not a spectacle, a sea of griefs is not a proscenium, and a man who wails is not a dancing bear.
Loving if the answering breast Seem not to be thus possessed, Still in hoping have a care; If it do, beware, beware! But if in yourself you find it, Above all things mind it, mind it!
The four cautions: Beware a woman in front of you, beware a horse behind of you, beware a cart beside of you, and beware a priest every which way.
The genetic code is not a binary code as in computers, nor an eight-level code as in some telephone systems, but a quaternary code with four symbols. The machine code of the genes is uncannily computerlike.
I always tried to be correct, not politically correct.
Beware Okonkwo!" she warned. "Beware of exchanging words with Agbala. Does a man speak when a god speaks? Beware!
What we have to understand that we have to believe into things which can be proved. Now the time has come that Divine itself has to be proved. That God Almighty has to be proved. That Christ as a son of God has to be proved, that His birth as immaculate conception has to be proved. Not by argument, not by reasoning, nor by blind faith but by actualization on your central nervous system.
The more you believe it, the more it starts to become real for you. This is why it is so very important to believe in positive things, rather than negative things. Whatever you believe, you will find that you are correct. The universe has a way of presenting to you exactly what you believe. If you think life is great, you are correct. If you think life is tough, you will be proved correct too.
When young, beware of fighting; when strong, beware of sex; and when old, beware of possession.
Beware of the dogs, beware of the evil workers, beware of those who mutilate the flesh!
I went back into politics only when it was clear that things weren't going as they should have in my party. I was always arguing, I argued with everyone - with my father, with the leaders I had known since I was a child...and one day, it was in 1955, one of them exclaimed, 'You do nothing but criticize! If you think you can correct things, correct them. Go ahead, why don't you try?' Well, I could never resist a challenge, so I tried.
Perhaps we could write code to optimize code, then run that code through the code optimizer?
It was a rather extraordinary conversation if you think about it -- both of us speaking in code. But not military code, not Intelligence or Resistance code -- just feminine code.
