Jon Jensen

I live in Provo, Utah and work at End Point Dev on various Internet-related projects: web applications, databases, e-commerce, scalability, system administration, and security, and occasionally, Android app 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 quotation

We have heard men who hold the priesthood remark that they would do
anything they were told to do by those who preside over them — even if
they knew it was wrong. But such obedience as this is worse than folly
to us. It is slavery in the extreme. The man who would thus willingly
degrade himself should not claim a rank among intelligent beings until
he turns from his folly.
        A man of God would despise this idea. Others, in the extreme
exercise of their almighty authority have taught that such obedience was
necessary, and that no matter what the Saints were told to do by their
presidents, they should do it without any questions.
        When Elders of Israel will so far indulge in these extreme notions
of obedience as to teach them to the people, it is generally because
they have it in their hearts to do wrong themselves.

—Joseph Smith, Millennial Star, vol. 14, number 38, p. 593–595

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″).

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