“ In the beginning, it seemed like a dead end job. But at least I had a job. And frankly, it was easy. After two weeks, I knew all I needed to know, and it freed my mind. The job allowed me to dream about what my life could become. ”

“ If we see a class as a restaurant, your illustration makes sense. But from my point of view, we don’t know the name of the restaurant, nor its menu. We just sit and cry for “Spaghetti!”, and sometimes the
waiter says “I’m sorry”. ”

“ A lot of overengineering has been justified in the name of flexibility. But more often than not, excessive layers of abstraction and indirection get in the way. Look at the design of software that really empowers the people who handle it; you will usually see something simple. Simple is not easy. ”

“ In the technocratically constructed, written, and functionalized space in which the consumers move about, their trajectories form unforeseeable sentences, partly unreadable paths across a space. Although they are composed with the vocabularies of established languages (those of television, newspapers, supermarkets, or museum sequences) and although they remain subordinated to the prescribed syntactical forms (temporal modes of schedules, pardigmatic orders of spaces, etc.), the trajectories trace out the ruses of other interests and desires that are neither determined nor captured by the systems in which they develop. ”

Michel deCerteau

In medicine, the Valsalva maneuver is performed by forcibly exhaling against closed lips and pinched nose, forcing air into the middle ear if the Eustachian tube is open. This maneuver with slight modifications can be used as a test of cardiac function and autonomic nervous control of the heart or to �clear� the ears (equalize pressure) when external pressure increases, as in diving or aviation.
