Answer by Jim Dennis on Stack Overflow question http://stackoverflow.com/questions/1218390/what-is-your-most-productive-shortcut-with-vim/1220118#1220118

Your problem with Vim is that you don't grok vi.

You mention cutting with yy and complain that you almost never want to cut whole lines. In fact programmers, editing source code, very often want to work on whole lines, ranges of lines and blocks of code. However, yy is only one of many way to yank text into the anonymous copy buffer (or "register" as it's called in vi).

The "Zen" of vi is that you're speaking a language. The initial y is a verb. The statement yy is a simple statement which is, essentially, an abbreviation for 0 y$:

0 go to the beginning of this line. y yank from here (up to where?)

If you were to give recommendations to your "little brother/sister" on things that they need to do to become a data scientist, what would those things be?

I think the "Data Science Venn Diagram" (http://drewconway.com/zia/2013/3/26/the-data-science-venn-diagram) is a great place to start. You need three things to be a good data scientist:

• Statistical knowledge
• Programming/hacking skills
• Domain expertise

Statistical knowledge
