Can complexity emerge from lower levels of simplicity?
‘Is there really a Universe that is not designed from the top downwards but from the bottom upwards? Can complexity emerge from lower levels of simplicity?’ It has always struck me as being bizarre that the idea of God as a creator was considered sufficient explanation for the complexity we see around us, because it… Continue reading Can complexity emerge from lower levels of simplicity?

Using anonymous functions and closures for user-defined array sorting
Anonymous functions and closures are relatively new in PHP, but they’re extremely welcome. Whenever you need to sort an array with a custom order (that is, with a user-defined comparison function such as usort, uasort or uksort) you can use anonymous functions and closures in an easy and very straight-forward way.
