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:

God in His infinite mercy has revealed to us a great truth. It is a truth that, when understood by us, gives a new light to our existence and inspires us with the most exalted hopes. That truth is that God is our Father, and we are His children. What a tender relationship! What a feeling of nearness it creates within us! What? God my Father? Am I indeed His son? Am I indeed His daughter? Do I belong to the family of God? Is this literally true? The answer is, ‘Yes.’ God has revealed it, that we are literally His children, His offspring, that we are just as much His children as our offspring are our children, that He begot us, and that we existed with Him in the family relationship as His children.

What an immensity of vision is given to us in this truth! What a field for reflection! And how our hearts should be inspired with great hopes and anticipations to think that the Being under whose direction this earth was organized, who governs the planets and controls the universe, who causes the rotation of the seasons and makes this earth so beautiful and such a delightful place of habitation, is our Father and that we are His children, descended from Him! What illimitable hopes the knowledge of this inspires us with!

Now, this is the truth. We humble people, we who feel ourselves sometimes so worthless, so good-for-nothing, we are not so worthless as we think. There is not one of us but what God’s love has been expended upon. There is not one of us that He has not cared for and caressed. There is not one of us that He has not desired to save and that He has not devised means to save. There is not one of us that He has not given His angels charge concerning. We may be insignificant and contemptible in our own eyes and in the eyes of others, but the truth remains that we are the children of God and that He has actually given His angels — invisible beings of power and might — charge concerning us, and they watch over us and have us in their keeping.

—George Q. Cannon, Gospel Truth, 1:1–2

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. 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.
