* 最近在研究怎麼用 Docker 來錄影像跟聲音，所以參考了[https://github.com/elgalu/docker-selenium elgalu/docker-selenium]
  * 源自於搜尋到一個解法是用 [https://github.com/zalando/zalenium Zalenium]
  * 使用 [https://github.com/elgalu/docker-selenium elgalu/docker-selenium] 同時錄聲音影像的相關討論: https://github.com/elgalu/docker-selenium/issues/147
    * https://github.com/elgalu/docker-selenium/issues/147#issuecomment-294318491 談到可以錄到聲音

* 意外發現該專案有一份使用狀況的分析
  * [[Image(https://raw.githubusercontent.com/elgalu/docker-selenium/master/images/ga-datastudio-docker-selenium.png)]]
  * 甚至還用了 [https://datastudio.google.com/u/0/reporting/0B3GcHpfNB6-FRDd3RWo1ZWh4N3M Google DataStudio] 來做報表
* 加上在一些 docker 執行的 Log 裡面出現一段有使用 GA 進行追蹤的宣告
