Permaculture principles There are two basic steps to good permaculture design. The first deals with laws and principles, while the second is more closely associated with practical techniques. The principles are inherent in any permaculture design, in any climate, and at any scale. They are, briefly: Relative location: every element is placed in relationship to another so that they assist each other Each element performs many functions. Each important function is supported by many elements. Efficient energy planning for house and settlement. Emphasis on the use of biological resources over fossil fuel resources. Energy recycling on site. Using and accelerating natural plant succession to establish favourable sites and soils. Polyculture and diversity of beneficial species for a productive, interactive system. Use of edge and natural patterns for best effect. Bill Mollison, Introduction to Permaculture principles
Software developers have stopped caring about reliability An Article by Drew DeVault drewdevault.com Of all the principles of software engineering which has fallen by the wayside in the modern “move fast and break things” mentality of assholes modern software developers, reliability is perhaps the most neglected, along with its cousin, robustness. Almost all software that users encounter in $CURRENTYEAR is straight-up broken, and often badly. softwareprinciples
The rational model of design Engineers seem to have a clear, if usually implicit, model of the process of design. It is usually an orderly model of an orderly process as the engineer conceives it. The notion that the design process should be modeled as a systematic step-by-step process seems to have first developed in the German mechanical engineering community. Herbert Simon independently argues for design as a search process in The Sciences of the Artificial. He was motivated to lay out a strictly rational model of design precisely because such a model was a necessary precursor to automating design. His model remains influential even if today we recognize the "wicked problem" of original design as one of the least promising candidates for AI. In software engineering, Winston Royce independently introduced a seven-step Waterfall Model to bring order to the process. In fact, Royce introduced his waterfall as a straw man that he then argued against, but many people have cited and followed the straw man rather than his more sophisticated models. Even if ironically, Royce's seven-step model must be considered one of the foundational statements of the Rational Model of Design. Frederick P.
