Documentation Samples

Here are some samples of my technical writings to give some glimpse into my skills in that area. Included are some documents in differing styles, such as: instruction, proposal, planning, and thoughts on the responsibility of an IT organization to the system it maintains.


  • dbcluster/

    Implementation of a highly available PostgreSQL cluster using DRBD on RHEL5.

    Thoughts on the ethical obligations of IT to the company at large. IT enjoys a unique position of responsibility within a company.
