Jon C. Jensen

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.

A quotation

[quotation #821 of collection of 885 · previous · next · another random quotation]

Fundamentalists are not always the type who seize you by the throat with one fist while thumping the table with the other. There are plenty of soft-spoken, self-effacing examples of the species. It isn’t a question of style. Nor is the opposite of fundamentalism lukewarmness, or the tiresome liberal prejudice that the truth always lies somewhere in the middle. Tolerance and partisanship are not incompatible. Anti-fundamentalists are not people without passionate beliefs; they are people who number among their passionate beliefs the conviction that you have as much right to your opinion as they have. And for this, some of them are certainly prepared to die. The historian AJP Taylor was once asked at an interview for an Oxford fellowship whether it was true that he held extreme political beliefs, to which he replied that it was, but that he held them moderately. He may have been hinting that he was a secret sceptic, but he probably just meant that he did not agree with forcing his beliefs on others.

The word “fundamentalism” was first used in the early years of the last century by anti-liberal US Christians, who singled out seven supposed fundamentals of their faith. The word, then, is not one of those derogatory terms that only other people use about you, like “fatso”. It began life as a proud self-description. The first of the seven fundamentals was a belief in the literal truth of the Bible; and this is probably the best definition of fundamentalism there is. It is basically a textual affair. Fundamentalists are those who believe that our linguistic currency is trustworthy only if it is backed by the gold standard of the Word of Words. They see God as copperfastening human meaning. Fundamentalism means sticking strictly to the script, which in turn means being deeply fearful of the improvised, ambiguous or indeterminate.

Fundamentalists, however, fail to realise that the phrase “sacred text” is self-contradictory. Since writing is meaning that can be handled by anybody, any time, it is always profane and promiscuous. Meaning that has been written down is bound to be unhygienic. Words that could only ever mean one thing would not be words. Fundamentalism is the paranoid condition of those who do not see that roughness is not a defect of human existence, but what makes it work. For them, it is as though we have to measure Everest down to the last millimetre if we are not to be completely stumped about how high it is. It is not surprising that fundamentalism abhors sexuality and the body, since in one sense all flesh is rough, and all sex is rough trade. …

Fundamentalists are really necrophiliacs, in love with a dead letter. The letter of the sacred text must be rigidly embalmed if it is to imbue life with the certitude and finality of death. Matthew’s gospel, in a moment of carelessness, presents Jesus as riding into Jerusalem on both a colt and an ass—in which case, for the fundamentalist, the Son of God must indeed have had one leg thrown over each.

The fundamentalist is a more diseased version of the argument-from-the-floodgates type of conservative. Once you allow one motorist to throw up out of the car window without imposing a lengthy prison sentence, then before you know where you are, every motorist will be throwing up out of the window all the time, and the roads will become impassable. It is this kind of pathological anxiety, pressed to an extreme, which drove the religious police in Mecca early last year to send fleeing schoolgirls back into their burning school because they were not wearing their robes and head dresses, and which inspires family-loving US pro-lifers eager to incinerate Iraq to gun down doctors who terminate pregnancies. To read the world literally is a kind of insanity.

Work talks

Presentation slides from talks I have given at technical conferences and company-wide meetings are available.

Free software

I support free software and open source. Don’t be a sharecropper!

I am on GitHub as jonjensen and have contributed to projects including PostgreSQL, Interchange, DevCamps, and Bucardo. I also keep old miscellaneous scripts around.

Other free software I work most often with: awesome, alacritty, kitty, tmux, Screen, zsh, bash, Firefox, Chromium, Vim, Git, Rust, Go, Perl, Python, Ruby, PHP, PostgreSQL, Linux (mostly Red Hat/CentOS, Fedora, Ubuntu, Debian), Android, OpenBSD, OpenSSH, Apache httpd, nginx, Postfix, Dovecot, Pine (now Alpine), Signal, GnuPG, Standard Notes, Zulip, MediaWiki, VLC, rsync, ripgrep, mtr, and Nmap, just as a sampling. Thanks to all free software developers for your time and efforts!

Once upon a time I created some RPM packages of free software for use on Fedora Linux. The source RPMs may still prove useful for building on a newer version.

Human languages

Some Unicode things I keep handy:

Language family maps for reference:

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″).

Writing

Some of my free verse:

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

Good causes

A few organizations I support:

Religion

Links about religion:

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!

Hymns:

Liberty

Miscellany

mod.zayda.net is a collection of old Amiga-era music “modules”, including the whole U4ia and F8 collection by Jim Young, mostly created on his Amiga.
