The fundamental problem with program maintenance is that fixing a defect has a substantial (20-50 percent) chance of introducing another. So the whole process is two steps forward and one step back.
Testing is the process of comparing the invisible to the ambiguous, so as to avoid the unthinkable happening to the anonymous.
A good threat is worth a thousand tests.
If you can't test it, don't build it. If you don't test it, rip it out.
Bugs lurk in corners and congregate at boundaries.
I find that writing unit tests actually increases my programming speed
There is a construct in computer programming called 'the infinite loop' which enables a computer to do what no other physical machine can do - to operate in perpetuity without tiring. In the same way it doesn't know exhaustion, it doesn't know when it's wrong and it can keep doing the wrong thing over and over without tiring.
Children's programming in America, I think it's pretty shoddy in terms of lack of diversity. It's pretty much cartoons and Disney sort of shows. I don't find any of that stimulating for children.
The whole cable-TV original programming just changed the nature of television.
Programming in machine code is like eating with a toothpick
I hope to see Ruby help every programmer in the world to be productive, and to enjoy programming, and to be happy. That is the primary purpose of Ruby language.
I believe that the purpose of life is, at least in part, to be happy. Based on this belief, Ruby is designed to make programming not only easy but also fun. It allows you to concentrate on the creative side of programming, with less stress.
Often people, especially computer engineers, focus on the machines. But in fact we need to focus on humans, on how humans care about doing programming or operating the application of the machines.
I don't know how to stop it, there was never any intent to write a programming language [...] I have absolutely no idea how to write a programming language, I just kept adding the next logical step on the way.
Just as someone who's been interested in radio and programming for so long, I can usually tell when an interviewer is doing a segment just to fill a programming slot. They ask questions, but they don't care about the answers.
It's never too late to change the programming imprinted in childhood, carried in our genes or derived from previous lives; the solution is mindfulness in the present moment.
You are being programmed all day, every day. You can't stop it, but you can determine if the programming is positive or negative.
AMC is a fantastic network that does diverse programming, and does it at a really good level and of great quality.
If they can shut down ABC News and ABC network programming just because they don't agree on something, it makes you wonder
Your choice of programming model also is your choice of programming model, so to speak.
New management at Nine has launched a concerted attack on its cost base in order to restore margins through eliminating waste, improving efficiency and lowering programming costs.
A programming language that is sort of like Pascal except more like assembly except that it isn't very much like either one, or anything else. It is either the best language available to the art today, or it isn't.
The reason why people think of programming as being hard is because you're writing down a general rule which is going to be used for lots of instances that a particular instance must process correctly.
[A]ll the categories of creatures act individually as special-case and may be linearly analyzed; retrospectively, it is discoverable that inadvertently they are all interaffecting one another synergetically as a spherical, interprecessionally regenerative, tensegrity spherical integrity. Geodesic spheres demonstrate the compressionally discontinuous--tensionally continuous integrity. Ecology is tensegrity geodesic spherical programming.
When we had no computers, we had no programming problem either. When we had a few computers, we had a mild programming problem. Confronted with machines a million times as powerful, we are faced with a gigantic programming problem.
