Projects and Links

The PFCS team is involved in our own commercial offerings as well as a number of other technical projects and non-profit works:

PFCS Corporation’s Unix MUMPS

MUMPS is a powerful string manipulation language with an embedded database. It is best suited for applications that store and access large, random databases and capable of providing arbitrary precision arithmetic, unlimited subscript, data, and variable storage. PFCS Corporation’s Unix MUMPS is a high-performance, well-integrated MUMPS implementation for Unix that exceeds the ANSI X11.1-1990 MUMPS Standard.

Industry- and task-relevant applications of Unix MUMPS include:  health care, accounting and finance, manufacturing and inventory control, telemarketing, shipping, publications libraries, law enforcement, facilities management, office automation, human resources management, full-text search and retrieval, sales management and order tracking, and computer-based instruction.

Unix MUMPS has its own project page.

Other Projects

Network Time Protocol

PFCS Corporation’s owner, Harlan Stenn, is the primary maintainer of the open source Network Time Protocol project, as well as the Program Manager of the NTP Support Project. He has brought his many years of programming and software engineering experience to move the project forward.


The PIKT project offers a toolset that supports global-view, site-at-a-time system and network administration.


The Arusha Project (ARK) provides a framework for collaborative system administration of multi-platform Unix sites with many dozens of machines.

Environment Modules

The Environment Modules package provides for the dynamic modification of a user’s environment via module files.

Modules makes it easy to provide each process with specific versions of every software tool it needs.

Interesting links

Here are some links to a few places we like:

  • Wings Seminars
    offers (spectacular, in Harlan’s opinion) personal growth educational seminars.
  • The Gigapxl Project
    defines the upper-limit of large-format photography, digital scanning, and image processing.
