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?)

While permanently null fields and large unwieldy tables are conceptually ugly, they generally don't actually cause any real inefficiency. The extra space used by null fields is not an important consideration for most systems, and the query speed will not be slower if you set up your indexes well.

And the benefits of STI are often worthwhile (database efficiency by minimizing joins, and shared code simplicity and DRYness). So if you are going to use a traditional SQL system, just learn to ignore the conceptual ugliness and use STI. Your use case is what STI was designed for.

That said, if you are not too deep in your development cycle for this project to be attached to your database system (and it sounds like you're not), and you are willing to invest some time to research/learning, you really might want to consider an alternative to SQL (there are many good ones out there). Currently the most popular alternative (and my personal favorite) is MongoDB.

MongoDB is document-based rather than schema-based. This

find the file pg_hba.conf - it may be located, for example in /etc/postgresql-9.1/pg_hba.conf.

cd /etc/postgresql-9.1/

Back it up

cp pg_hba.conf pg_hba.conf-backup

place the following line (as either the first uncommented line, or as the only one):
