Enter Integrant: A Micro-framework for Data-Driven Architecture -> 心得

Integrant 是什麼？解決了什麼問題？

  • integrant 是 micro-framework ，處理類似 component, mount 在處理的問題。

比較競品

component 與 mount：

功能是讓 application 裡頭含有 app state 的部分與 code 分開，可以獨立地重新載入。

Transparency through Data --- James Reeves

  1. Transparency -> understanding -> prediction

  2. Constraints narrow down possibilities.

    • static types
    • immutability
    • pure function

  3. 以搜尋字串來舉例，看看下列的實作，哪一個比較容易預測？哪一個容易理解？

    • clojure 的實作：不保証程式會停。
    • re-find 的實作：保証一定會停。
  • RE2/J 的實作：會停而且只使用 linear 的時間。

Effective communications

Effective communications

  • Communication -> Effective process -> Results
  • The four principles
  • The tool set
  • The five essential questions

The four principles

  1. Communication is perception
    • It is the recipient who commuicates.
  • It is experience, not logic. One cannot communicate a word; the whole man always comes with it.
