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?)

Falsehoods programmers believe about prices

You can store a price in a floating point variable.
All currencies are subdivided in 1/100th units (like US dollar/cents, euro/eurocents etc.).
All currencies are subdivided in decimal units (like dinar/fils)
All currencies currently in circulation are subdivided in decimal units. (to exclude shillings, pennies) (counter-example: MGA)
All currencies are subdivided. (counter-examples: KRW, COP, JPY... Or subdivisions can be deprecated.)
Prices can't have more precision than the smaller sub-unit of the currency. (e.g. gas prices)
For any currency you can have a price of 1. (ZWL)
Every country has its own currency. (EUR is the best example, but also Franc CFA, etc.)

How to increase the root partition size on Fedora

Boot up with an Fedora Live USB stick.

Run vgs to check if there's any space:

$ sudo vgs
  VG     #PV #LV #SN Attr   VSize    VFree
  fedora   1   3   0 wz--n- <237.28g    0

	CREATE FUNCTION `lat_lng_distance` (lat1 FLOAT, lng1 FLOAT, lat2 FLOAT, lng2 FLOAT)

	BEGIN
	RETURN 6371 * 2 * ASIN(SQRT(
	POWER(SIN((lat1 - abs(lat2)) * pi()/180 / 2),
	2) + COS(lat1 * pi()/180 ) * COS(abs(lat2) *
	pi()/180) * POWER(SIN((lng1 - lng2) *
	pi()/180 / 2), 2) ));
	END
