從 Plurk 錯誤訊息看寫作風格

剛不小心去按 plurk, 發現跑出一段 error code:

Traceback (most recent call last):

從這邊可以看到 plurk 的一些寫作風格, ...

1. Python, 廢話
2. MySQL, 這也猜得出來
3. Object Oriented, 這已經是主流了
4. werkzeug Library, 做為前台 UI Framework?
5. wsgiServer API, 這我也沒用過..

最近, plurk 的邀請網址也改成人讀了, 如 http://plurk.com/genehong/invite , 大家可以去玩玩看...
