The USPS delivers mail in the United States. A key part of this delivery system are systems which read handwritten and printed addresses on envelopes, use optical character recognition (OCR) to convert them to text, and extract routing information from them. These systems now consist of 5 Linux computers per unit.

There are now over 6000 Linux computers deployed throughout the U.S. reading the mail.

Note: the contact (John Taves) is not a USPS employee, but was involved in designing this system. He is an independent consultant.

• X-Windows:

  • X-Windows server (runs applications, possibly exports display)
• Office productivity software:
