Jon Jensen

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:

If you want to build a factory, or fix a motorcycle, or set a nation right without getting stuck, then classical, structured dualistic subject-​object knowledge, although necessary, isn’t enough. You have to have some feeling for the quality of the work. You have to have a sense of what’s good. That is what carries you forward. This sense isn’t just something you’re born with, although you are born with it. It’s also something you can develop. It’s not just “intuition,” not just unexplainable “skill” or “talent.” It’s the direct result of contact with basic reality, Quality, which dualistic reason has in the past tended to conceal.

—Robert M. Pirsig, Zed and the Art of Motorcycle Maintenance, 1974 & 1984, p. 255

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.
