„Even perfect program verification can only establish that a program meets its specification. [… ] Much of the essence of building a program is in fact the debugging of the specification.“

„One can even conjecture that Lisp owes its survival specifically to the fact that its programs are lists, which everyone, including me, has regarded as a disadvantage.“

„Word and Excel and PowerPoint and other Microsoft programs have intimate — one might say promiscuous — knowledge of each others' internals. In Unix, one tries to design programs to operate not specifically with each other, but with programs as yet unthought of.“

„Power in Russia today is the power that's established, mounted. It arises anew and it's authoritarian in its technology, but not in its program. It doesn't know which one it wants to be and can be — this depends on its future programming by people, i. e. you.“

—  Gleb Pavlovsky Russian political scientist 1951

"Сегодня власть в России — власть устанавливаемая, учредительная власть. Она возникает заново и авторитарна по технологии, но не по своей программе. Она еще не знает, какой хочет и может быть, — это зависит от будущего ее программирования людьми, то есть вами."

„If the users don't control the program, the program controls the users. With proprietary software, there is always some entity, the "owner" of the program, that controls the program—and through it, exercises power over its users. A nonfree program is a yoke, an instrument of unjust power.“

—  Richard Stallman American software freedom activist, short story writer and computer programmer, founder of the GNU project 1953

A Conversation with Ward Cunningham (2003), Exploring with Wiki
Contexto: My specific purpose for the first wiki was to create an environment where we might link together each other's experience to discover the pattern language of programming. I had previously worked with a HyperCard stack that was set up to achieve the same kind of goal. I knew people liked to read and author in that HyperCard stack, but it was single user.

“Special Forces” Innovation: How DARPA Attacks Problems (2013)
Contexto: Over the past 50 years, the Pentagon’s Defense Advanced Research Projects Agency (DARPA) has produced an unparalleled number of breakthroughs. Arguably, it has the longest-standing, most consistent track record of radical invention in history. Its innovations include the internet; RISC computing; global positioning satellites; stealth technology; unmanned aerial vehicles, or “drones”; and micro-electro-mechanical systems (MEMS), which are now used in everything from air bags to ink-jet printers to video games like the Wii. Though the U. S. military was the original customer for DARPA’s applications, the agency’s advances have played a central role in creating a host of multibillion-dollar industries.
What makes DARPA’s long list of accomplishments even more impressive is the agency’s swiftness, relatively tiny organization, and comparatively modest budget. Its programs last, on average, only three to five years.
