软件开发从业者寻食记

关键字：软件开发 python google appengine 好吃 便宜 打折 信用卡

每天到了晚上就在想去哪儿吃饭呢？能打折，便宜。 每次坐电梯和收到信用卡账单的时候都能看到一大批打折饭店的信息。折扣力度还很大，都是5折，可就是每家饭店都有固定的打折日期，每周轮一回，譬如周一哪家店，周二哪家店。

信息来源好多地方都有，电梯里分众的广告，信用卡DM的广告，网站。可是忽然要用的时候却很难找到，不知道分类信息网站现在活的怎么样，要是能够查到就好了。

等别人做还不如自己做呢，google appengine那么敏捷。

域名是在google domain里申请的，绑定了appengine
