首先建立数据模型。在这里可以下载到 Stack Overflow 往年的帖子,解压缩之后是一个 26GB 的 xml 文件。这个文件是由过往所有的帖子组成,每个帖子还有具体的时间、标题、标签、正文、评论等等。可惜 Power Query 不能很好地以流模式处理这个 xml 文件,直接导入将会导致内存不够的异常,囧。 为今之计,只有通过代码简...
Stack Overflow是世界各地开发者交流技术的地方,不但有各路高手回答问题分享经验,而且还提供对所有帖子的检索,绝对是一个知识宝库。每每看到别人动辄几万而我刚刚过千的声望,总希望投资一个有潜力的编程语言方便混分。心动不如行动,让我们借助Power BI分析一下。 思路很简单,只要对Stack Overflow帖子进行统计,一定能够...
心动不如行动,让我们借助 Power BI 分析一下。 思路很简单,只要对 Stack Overflow 帖子进行统计,一定能够找到一些端倪,能够让我们一窥编程的大势走向。比如,Stack Overflow 本身是基于 C# 以及 SQL Server 开发运营的,这点让许多 Java 粉丝扼腕。那么到底是 C# 还是 Java 在 Stack Overflow 上更火爆呢?好在 Stack...

This skepticism is unfounded, as evidenced by a StackOverflow survey where 28% of respondents identified themselves as full stack web developers. These professionals are characterized by their comprehensive understanding of all the stack layers, though they typically possess deeper expertise in specific ...
