A Quote by Edsger Dijkstra
Progress is possible only if we train ourselves to think about programs without thinking of them as pieces of executable code.

Don't worry over what other people are thinking about you. They're too busy worrying over what you are thinking about them. If one dream should fall and break into a thousand pieces, never be afraid to pick one of those pieces up and begin again.
We may make progress only by freeing ourselves from the rut of the past, but without this rut an orderly society would hardly be possible in the first place.
When we are not engaged in thinking about some definite problem, we usually spend about 95 percent of our time thinking about ourselves. Now, if we stop thinking about ourselves for a while and begin to think of the other person's good points, we won't have to resort to flattery so cheap and false that it can be spotted almost before it is out of the mouth.
Python is executable pseudocode. Perl is executable line noise.
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.
The time I like listening to music most on headphones is, I have a game I play with my brother, he's a musician as well.And he sends me MIDI files of keyboard pieces. So, these are pieces where I just get a MIDI file; I don't know what instrument he was playing them on; I know nothing about his section of the sound of the piece, and then when I'm sitting on trains I do a lot of train travel I turn them into pieces of music. And I love to do that; it's my favorite hobby.
We should think more about it, and accustom ourselves to the thought of death. We can't allow the fear of death to creep up on us unexpectedly. We have to make the fear familiar, and one way is to write about it. I don't think writing and thinking about death is characteristic only of old men. I think that if people began thinking about death sooner, they'd make fewer foolish mistakes.
We are trying to prove ourselves wrong as quickly as possible, because only in that way can we find progress.
Simply put, when you have very large pieces of software, most of the tools look at the individual lines of code as text. It is often extremely powerful to look not at individual pieces of code but at a system as a whole.
I’m a big believer in starting with high standards and raising them. We make progress only when we push ourselves to the highest level. If we don’t progress, we backslide into bad habits, laziness and poor attitude.
Pride is a terrible and dangerous thing. It can take so many forms; it can even assume the appearance of humility. Pride can lead not only to self-exaltation, but also to self-abasement. The key to battling pride is not found in struggling against thinking too highly of ourselves or in striving to think of ourselves as lowly. The key is found in simply not thinking about ourselves at all, but setting our minds on Christ and the needs of others.
The trick generally is to break programs into pieces and have those pieces be individually testable and so then when you move on to the other pieces you treat it as a black box knowing that it either works or doesn't work.
There's a definite sense this morning on the part of the Kerry voters that perhaps this is code, 'moral values,' is code for something else. It's code for taking a different position about gays in America, an exclusionary position, a code about abortion, code about imposing Christianity over other faiths.
A programming language is for thinking about programs, not for expressing programs you've already thought of. It should be a pencil, not a pen.
You know, there's a real irony in U.S. assistance programs. First of all, I think it's misnamed. We're not so much trying to help people as we're trying to help ourselves. So let's be clear about this. So these are - in my view, they're cold calculations of national security and not aid programs.
It is a mistake to think that programmers wares are programs. Programmers have to produce trustworthy solutions and present it in the form of cogent arguments. Programs source code is just the accompanying material to which these arguments are to be applied to.
