Index compression script generation
I wrote a script to generate script for non-clustered index page compression in SQL Server. I’ve since made improvements and here it is. Highlights: This script generates index compression script on a partition by partition basis, if the underlying index is partitioned; Like the previous version, it still works for non-partitioned indexes; Like the previous […]

Yanking and sorting lines matching a pattern
One of the best investments I’ve ever made is to be proficient with a good cross-platform editor, in my case Vim. It took me a good few months before I really became comfortable with it, but those few months’ struggle yielded huge dividend since then! So after years of Vim usage, I consider myself a […]

建立中文版Linux虚拟机
最近在几个QQ和微信IT群里灌水，注意到不少同学在大学或工作中没接触过Linux。而很多IT项目如大数据、机器学习、服务器等都需要Linux技能，所以很多人想开始接触、学习Linux。我就动手做了以下视频给初学者，希望能有帮助。这是我第一次做screencast，很希望能听到你的批评和建议。 更新：视频上传到优酷后，效果并不理想。我又尝试了其它视频分享网站如乐视、QQ视频、新浪视频、和土豆。乐视的上传网页没有上传渠道，或许因为我的IP地址在国外？我在新浪视频网页也碰到同样问题。QQ视频倒是允许上传，但最终告诉我“您的视频可能包含有相关主管机关明确规定不能出现的违规内容，因此无法通过审核。请修改后再重新上传。”，真是令人匪夷所思。 最后上传到土豆，效果还可以。我是把几个小视频合并到一个文件，但由于操作错误，我没有把一开始介绍VirtualBox软件的那部分合并进去。你只要记得VirtualBox在Windows、Linux、Mac上都可以免费运行并去下载安装就可以啦。

Convert Excel file with hyperlinks to CSV

According to CSV wikipedia page, IBM Fortran started supporting this format in 1967, before many of us were born.
