useful programs:

Eve-MEEP is the host for a wide array of tools that provide the
vital calculations necessary for any serious industrialist. These tools take advantage of data accumulated by Eve-MEEP via the Eve-Online API to help with everything
from production to mining to trade.

EveHQ is an extensible character application for use in conjunction with Eve-Online.
Initially starting out as a character monitor and skill planner, EveHQ adopted a plug-in system where additional modules could be created independently of the main application which would extend the functionality of the program as a whole.

EVEMon is a lightweight, easy-to-use standalone Windows application designed to assist you in keeping track of your EVE Online character progression. You can view your current skills and attributes, what you're currently training, and your ISK balance. EVEMon can track multiple characters across multiple accounts, so all your alts can be monitored through the same, simple interface.
