“"You can never be too safe." Yes, you can. How many of us bother to inspect the hydraulic brake lines in our cars before we start the engine and head off to work? Doing so would be safer than simply assuming that the lines were intact and driving off. After all, prior to launching a space vehicle, the people at NASA make no similar assumptions. They go through a countdown of all systems, taking nothing for granted. Erring on the side of over-caution is costly, and so is erring on the side of under-caution, though for a given choice, one might be costlier than the other.”

“We're adding a triple sign-off for all work done on the launch pad, on flight components, and flight critical GSE. You have a technician, a responsible engineer, and then quality assurance will sign the final, record all information, and take photographs of all the work that was done, and then make sure that all information is put into our quality assurance database, which is reviewed prior to launch.”

“I'm fed up with this Scottish waving of nationalism when it suits them. Alright, they're devolved, but I think they did this just to show the rest of us oh, that we are independent, we make our own decisions, and it's been very embarrassing for the rest of us. And it started me thinking along these lines, if Scotland wants to be independent, OK, be my guest, go ahead, do what you want and [Applause] please take back with you all the Scottish politicians - there's so many of them - you know - starting with Blair and Brown and Campbell, take them all back, and off you go, and go off on your own, because actually, we're all subsidising them I think, by way of benefits and all sorts of reasons, and if they want to show how independent they are, OK, thank you and goodbye.”

“Unix was small, and you could go through it line by line and understand exactly how it worked. That was the origin of the so-called Unix culture.”

Ken Thompson (1943) American computer scientist, creator of the Unix operating system

"Unix and Beyond: An Interview with Ken Thompson," 1999
Context: Unix was a very small, understandable OS, so people could change it at their will. It would run itself—you could type "go" and in a few minutes it would recompile itself. You had total control over the whole system. So it was very beneficial to a lot of people, especially at universities, because it was very hard to teach computing from an IBM end-user point of view.
