八. Distributed & concurrent
What to concurrent
Scalability
Stretch key dimensions to see what breaks
九. languages
Ruby
Erlang
assemble
C
C++

Python
Scala
Be ware of different program paradigms.
十. Performance
Minimize remote calls and other I/O
Speed-up data conversion
release resource as soon as possible
十一. architectures' future
軟件設計思想的發展邏輯，大致是提高抽象程度 ，separation of concern 程度。
fn(design )= fn1(abstraction )+ fn2(separation of concern).
由于大規模數據處理時代的來臨，下一代設計范式的重點：
1. 將是如何提高distributed(--concurrent) programing 的抽象程度 和 separation of concern 程度。
2. dsl ，按照以上的公式，也確實是一個好的方向。
