I live in Teton Valley, Idaho (near Yellowstone National Park) and work at End Point Corporation on various Internet-related projects: web applications, databases, e-commerce, scalability, system administration, and security, and occasionally, Android application development. I’m a radio amateur (“ham”) with call sign KG7TXN.

I write on the End Point blog and Somusing, blog of my wife, Erin.

A random quotation from my collection:

Furthermore, in spite of modern efficiency and resource substitution, the
per capita use of resources is extravagant and still growing to the point
where it is more accurate to say that we are living in a hyperindustrial
rather than a postindustrial age. Though they may use very little energy
while on the job [certainly not the case —JCJ], white-collar workers
who drive automobiles in long commutes use more energy getting to and
from work than their nineteenth-century counterparts used in order
to get the job done. One need only add to this the enormous resources
that are used for endless conferences and conventions attended by great
numbers of privileged bureaucrats, consultants and academics, so many of
which serve only as paid mini-vacations for those attending and produce,
for all the energy entailed, far less intellectual payoff than a good
correspondence or reading a good book, and the picture of the resource
profligacy of the so-called post-industrial world is complete.

—Max Dublin, Futurehype (1992)

More about some of my interests:

I support free software and open source. Don’t be a sharecropper! I contribute to projects including Interchange, DevCamps, and Bucardo, and keep some old scripts around.

Some Unicode things I keep handy:

Other free software I work most often with: Vim, GNU Screen, tmux, awesome window manager, Signal private messenger, Git, Perl, Ruby, Python, Go, Android, PHP, PostgreSQL, Linux (mostly Red Hat/Fedora, Ubuntu, Debian), OpenBSD, OpenSSH, Alpine, Postfix, Dovecot, GnuPG, rsync, mtr, and Nmap, just as a sampling. Thanks to all free software developers for your time and efforts!

Johann Sebastian Bach composed some of my favorite music. See these freely redistributable Bach sheet music PDFs and the James Kibbie complete Bach organ works recordings. Mutopia collects freely usable music scores. Thanks to those who typeset the music and gave it away!

Several years ago, a tree fell on our car, so I wrote up the story to share.

My novice linguistics research: I wrote a paper for Linguistics 490 (senior seminar) taught by John Robertson, winter semester 1998 at Brigham Young University. It examines how Hebrew verb patterns (binyanim) may be semantically grouped using C.S. Peirce’s universal categories. The paper: Hebrew Verb Pattern Tendencies Clarified by Peirce’s Universal Categories (8.5" x 11"). Reference chart: Roots in various binyanim chart (11" x 17").

Some of my writing I’m putting online for longevity’s sake: You never told me.

Links about liberty: is a collection of old Amiga-era music “modules”, including the whole U4ia and F8 collection by Jim Young, mostly created on his Amiga.
