Simple Currency Monitor (SDK for Google App. Engine):
The system is tested in simple enviroment by using notebook and WIFI with 2 second interval automation job. It's not built up with multi-threading.
The sparking error message and alert are the indicators of the crashing between the operational command (from end user) and the automation command (in server). No matter how many crashes happened, correct information will show finally.
聲明：
本人絕對不建議求職者以代碼或習題去換取入職機會。今次我接受某公司的入職習題測試，只是因為我認為該公司裡已有比我的習題更複習、有趣的系統，及我太無聊和有新事物接觸而已。
90%以上的情況我都是不做入職習題，60%以上不做面試的Paper Test。多數埋位就吹水，唔啱Feel咪Bye咯~ 哈哈~
