As suggested by proponentsof the DRYprinciple (don'tRepeatYourself), whenelements that are logicallyrelateddon't changetogetheruniformly, keepingthem in synccan be problematic.
DRY (Don ' t RepeatYourself,不要做重复的工作)原则的支持者建议,当逻辑相关的元素没有被同时统一改变的话,很难保持他们的同步。
Though Microsoft, Intel and other vendors have greatly improved universal plug 'n' play compatibility, it's still not easy to sync the diverse combination of elements.
