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?)
Every so often I have to restore my gpg keys and I'm never sure how best to do it. So, I've spent some time playing around with the various ways to export/import (backup/restore) keys.

WEBrick is a Ruby library that makes it easy to build an HTTP server with Ruby. | |
It comes with most installations of Ruby by default (it’s part of the standard library), | |
so you can usually create a basic web/HTTP server with only several lines of code. | |
The following code creates a generic WEBrick server on the local machine on port 1234, |
Locate the section for your github remote in the .git/config
file. It looks like this:
[remote "origin"]
fetch = +refs/heads/*:refs/remotes/origin/*
url = git@github.com:joyent/node.git
Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/*
to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:
module ActiveRecord::UnionScope | |
def self.included(base) | |
base.send :extend, ClassMethods | |
end | |
module ClassMethods | |
def union_scope(*scopes) | |
id_column = "#{table_name}.#{primary_key}" | |
sub_query = scopes.map { |s| s.select(id_column).to_sql }.join(" UNION ") | |
where "#{id_column} IN (#{sub_query})" |
