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
A lightbulb is not an idea An Article by Ralph Ammer ralphammer.com With conventional placeholders, such as words, we can describe patterns for a large number of situations. On the other hand it is easy to fool yourself (and others) with words, since you can avoid to be specific. Any business meeting can confirm this. When you draw something you are forced to be specific — and honest. Our illustration of an “idea” from above is unconventional in the sense that it conveys specific original thoughts of what an idea is. It adds value to the words. And that is the catch: The drawing must be unconventional to support the conventional words. We have to make sure not to use “words in disguise”. Take a common illustration for “idea” for example, which haunts flip charts all over the world: the lightbulb. The lightbulb image works on a purely symbolic level, it only replaces the word “idea”. This image of a household item contains no original thought about what an idea is. While symbols like these work well as international replacements for words or icons to indicate a light switch for instance, they convey no nutritional value as illustrations — they are empty. wordsideassymbolsdrawing
