“The type of fig leaf which each culture employs to cover its social taboos offers a twofold description of its morality. It reveals that certain unacknowledged behavior exists and it suggests the form that such behavior takes.”

“Augmentation, on the other hand, Mr. President, is defined in the GAB as the act of filling up a deficiency in any existing P/A/P of an agency or office from savings in other items of the said agency’s appropriations, and therefore, a non-existent P/A/P cannot be funded by augmentation from savings.”

“In compliance with the Supreme Court ruling on the Disbursement Acceleration Program, a new general provision on the “Meaning of Augmentation” is proposed by your committee in Sec. 69 which states that savings cannot be used to augment a non-existent P/A/P through the use of an appropriation not otherwise authorized by the subject GAA, and that the existence of an appropriation for an allotment class, whether for Personal Services, MOOE, or Capital Outlays, in a P/A/P is necessary for purposes of augmentation.”

“Refactoring is a disciplined technique for restructuring an existing body of code, altering its internal structure without changing its external behavior. Its heart is a series of small behavior preserving transformations. Each transformation (called a 'refactoring') does little, but a sequence of transformations can produce a significant restructuring. Since each refactoring is small, it's less likely to go wrong. The system is also kept fully working after each small refactoring, reducing the chances that a system can get seriously broken during the restructuring.”

Martin Fowler (1963) British programmer
