摘要: 清宵的第83行代码来自这个简单的Life模型,非项目非社区贡献,纯业余时间自娱自乐。看了《药神》之后,对人生的感悟加深。回来没有写什么观后感,却是随便写了一段代码,构造一个极其简单的人生模型,算作总结思考了。

在中国程序媛中,他们的代码有什么样的魅力,Aone联合云栖社区、饿了么、钉钉、阿里云、天猫、口碑发起首届程序媛比码活动——不秀大长腿,秀高智商;不秀美图照,秀代码图,参与晒码互动游戏赢“83行代码”T恤!

我们来说说这群女工程师的第83行代码及代码背后的故事:

清宵:人生如码

我的第83行代码来自这个简单的Life模型,非项目非社区贡献,纯业余时间自娱自乐。
看了《药神》之后,对人生的感悟加深。回来没有写什么观后感,却是随便写了一段代码,构造一个极其简单的人生模型,算作总结思考了。
人生如码,以梦为马。珍惜所爱,精彩过好每一天!
