I live in Provo, Utah and work with Internet-related projects: web applications, databases, scalability, system administration, and security, and in the past, ecommerce and Android app development. I’m a radio amateur (“ham”) with call sign KG7TXN.
I sometimes write on Somusing, the blog of my wife, Erin, and wrote a lot on the End Point blog when I worked there.

[quotation #807 of collection of 885 · previous · next · another random quotation]
What guarantees the objectivity of the world in which we live is that this world is common to us with other thinking beings. Through the communications that we have with other men we receive from them ready-made harmonious reasonings. We know that these reasonings do not come from us and at the same time we recognize in them, because of their harmony, the work of reasonable beings like ourselves. And as these reasonings appear to fit the world of our sensations, we think we may infer that these reasonable beings have seen the same thing as we; thus it is that we know we haven’t been dreaming. It is this harmony, this quality if you will, that is the sole basis for the only reality we can ever know.A map of the route my son & I took on our 2019 trip to Armenia, Georgia, Ukraine, and Moldova: Jon and Seth itinerary in June 2019.

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″).
