* [爭取屬於自己的舞台](https://www.facebook.com/groups/ncku.embedded2015/permalink/677685349044620/)
  - [Open Projects](/embedded/openprojects): 展開幾項有特色的專案，希望一面培養學生的實做訓練，一面提昇在國際上的能見度 

* [PyCON Taiwan 議程徵稿最後一天](https://www.facebook.com/groups/ncku.embedded2015/permalink/678446135635208/)
* 今晚沒有安排 Lab，但請在 4 月 6 日前確認 [Lab 38](/embedded/Lab38), [Lab 39](/embedded/Lab39), [Lab 40](/embedded/Lab40), [Lab 41](/embedded/Lab41) 均充分完成
  - 依據 GitHub / Hackpad 上教師提供的建議去改進

* 可預約一對一輔導
