Freedom to Love or Not

From an email by Fred Rogers written on 25 Oct 1998, quoted in Tom Junod's December 2019 article "My Friend Mister Rogers" in The Atlantic:

God's nature has grown and grown and grown all through the ages. Yet at the heart of the original creation is that Word (call it Love, call it Grace, call it Peace ...), that essence which is lodged somewhere within each of us that longs for ultimate expression. If we choose to allow it to grow we'll be given help. If we choose otherwise we won't be forced. If there is such a thing as a "dark corner" of God's nature then I think it's God's refusal to go back on the promise of "the creation's freedom to love or not."

(cf 2018-09-10 - Thank You, Mr Rogers, 143 (2019-11-28), 2, 3 (2020-01-04), Love Abounds (2020-01-06), Mantra - Greater Love (2020-02-21), ...)

Regex vs HTML

So much fun, that philosophers and programmers (and other Picky Persons) can have quibbling over definitions and trivia ... for example, from some years ago an argument over whether (and when, and why, and why not) a regular expression ("regex") can recognize or parse HTML ("HyperText Markup Language") — from [1] in 2009:

You can't parse [X]HTML with regex. Because HTML can't be parsed by regex. Regex is not a tool that can be used to correctly parse HTML. As I have answered in HTML-and-regex questions here so many times before, the use of regex will not allow you to consume HTML. Regular expressions are a tool that is insufficiently sophisticated to understand the constructs employed by HTML. HTML is not a regular language and hence cannot be parsed by regular expressions. Regex queries are not equipped to break down HTML into its meaningful parts. so many times but it is not getting to me. Even enhanced irregular regular expressions as used by Perl are not up to the task of parsing HTML. You will never make me crack. HTML is a language of sufficient complexity that it cannot be parsed by regular expressions. Even Jon Skeet cannot parse HTML using regular expressions. Every time you attempt to parse HTML with regular expressions, the unholy child weeps the blood of virgins, and Russian hackers pwn your webapp. Parsing HTML with regex summons tainted souls into the realm of the living. HTML and regex go together like love, marriage, and ritual infanticide. The <center> cannot hold it is too late. The force of regex and HTML together in the same conceptual space will destroy your mind like so much watery putty. If you parse HTML with regex you are giving in to Them and their blasphemous ways which doom us all to inhuman toil for the One whose Name cannot be expressed in the Basic Multilingual Plane, he comes. HTML-plus-regexp will liquify the n​erves of the sentient whilst you observe, your psyche withering in the onslaught of horror. Rege̿̔̉x-based HTML parsers are the cancer that is killing StackOverflow it is too late it is too late we cannot be saved the trangession of a chi͡ld ensures regex will consume all living tissue (except for HTML which it cannot, as previously prophesied) dear lord help us how can anyone survive this scourge using regex to parse HTML has doomed humanity to an eternity of dread torture and security holes using regex as a tool to process HTML establishes a breach between this world and the dread realm of c͒ͪo͛ͫrrupt entities (like SGML entities, but more corrupt) a mere glimpse of the world of reg​ex parsers for HTML will ins​tantly transport a programmer's consciousness into a world of ceaseless screaming, he comes, the pestilent slithy regex-infection wil​l devour your HT​ML parser, application and existence for all time like Visual Basic only worse he comes he comes do not fi​ght he com̡e̶s, ̕h̵i​s un̨ho͞ly radiańc destro҉ying all enli̍̈́̂̈́ghtenment, HTML tags lea͠ki̧n͘g fr̶ǫm ̡yo​͟ur eye͢s̸ ̛l̕ik͏e liq​uid pain, the song of re̸gular exp​ression parsing will exti​nguish the voices of mor​tal man from the sp​here I can see it can you see ̲͚̖͔̙̩́t̲͎̩̱͔́̋̀ it is beautiful t​he final snuffing of the lie​s of Man ALL IS LOŚ͖̩͇̗̪̏̈́T ALL I​S LOST the pon̷y he comes he c̶̮omes he comes the ich​or permeates all MY FACE MY FACE ᵒh god no NO NOO̼O​O NΘ stop the an​*̶͑̾̾​̅ͫ͏̙̤g͇̫͛͆̾ͫ̑͆l͖͉̗̩̳̟̍ͫͥͨe̠̅s ͎a̧͈͖r̽̾̈́͒͑e n​ot ȓͧ̌aͨl̘̝̙̃ͤ͂̾̆ ZA̡͊͠͝LGΌ ISͮ̂҉̯͈͕̹̘̱ TO͇̹̺ͅƝ̴ȳ̳ TH̘͖́̉ ͠P̯͍̭O̚​N̐Y̡ H̸̡̪̯ͨ͊̽̅̾̎Ȩ̬̩̾͛ͪ̈́̀́͘ ̶̧̨̱̹̭̯ͧ̾ͬC̷̙̲̝͖ͭ̏ͥͮ͟Oͮ͏̮̪̝͍M̲̖͊̒ͪͩͬ̚̚͜Ȇ̴̟̟͙̞ͩ͌͝S̨̥̫͎̭ͯ̿̔̀ͅ

Have you tried using an XML parser instead?

... see [2] by the author — and for even more fun, the Chomsky Hierarchy of languages, and the fact that strictly-and-narrowly defined regular expressions aren't able to parse context-free grammars like HTML — yet extended regex's can parse HTML — and contrapositively (?!) true regex's can parse selected subsets of HTML.

So it's really all just a matter of definitions and (mis)understandings and parody ...

Mantra - Give Instead of Giving Up

Don't Give Up
    — Give!

Be positive! Rather than making a sacrifice and feeling the negative, try to see the situation from another perspective and find the plus side — the gift, the gain, the benefit. As Margaret Renkl says at the end of her essay "One Tiny Beautiful Thing":

Instead of giving up something for Lent, I'm planning to make a heartfelt offering. In times like these, it makes more sense to seek out daily causes for praise than daily reminders of lack. So here is my resolution: to find as many ordinary miracles as a waterlogged winter can put forth, as many resurrections as an eerily early springtime will allow. Tiny beautiful things are bursting forth in the darkest places, in the smallest nooks and deepest cracks of the hidden world, and I am going to keep looking every single day until I find one.

... and yes, it's so tough sometimes to make that inversion — and so wonderful when it somehow succeeds ...

Mark Jason Dominus

A thoughtful person who has been keeping an online journal (aka "blog") longer than the ZhurnalyWiki!Mark Jason Dominus wrote a book (2005) titled Higher-Order Perl, about the meta-activity of "Transforming Programs with Programs". He also composed the insightful "How Regexes Work" (cf Reg Explanations (2003-12-03)) and described the Pollyanna-like game "Advocacy" (cf Worse Is Better (2003-12-23)). And as of 2020 he's still posting with good humor and style. Bravo, Sir!

Small Eyes Notation

Adapted from the preface of "Coend Calculus", a paper on category theory by Fosco Loregian:

http://zhurnaly.com/images/eyes-wide-with-fear.png"Some of the exercises are marked with a symbol <<eyes wide with fear>> — this means they are more difficult and less well-posed questions than the others. This can happen on purpose (and thus part of the exercise is understanding what the question is) or not (and thus the question and its answer are not completely clear even to the author). In this second case, it is likely that a complete answer might result in new Mathematics that we'd be happy to expand with the solvers."
http://zhurnaly.com/images/eyes-looking-up.png"Other kinds of 'small eyes' are present along the book: the paragraphs decorated with <<eyes looking up>> contain material that can be skipped at first reading, or material that deepens a prior topic in a not-so-interesting detour."
http://zhurnaly.com/images/eyes-looking-right.png"<<eyes looking right>> is used to signal key remarks and more generally important material that we ask the reader to digest properly and analyse in full detail. "

Loregian comments:

The author learned this funny notation during his freshman year, when he was handed [a text by G. De Marco] for the first time; the "small-eyes" notation accompanied me throughout all my mathematical life until today. In [De Marco] this notation has the following meaning: various facial expressions explain the different ways the reader is supposed to behave when they meet them: <<eyes looking up>>, abstract material; <<eyes looking down>>, standard exercises; <<eyes looking right>>, material that you are supposed to meditate a lot; <<eyes wide open>>, shattering exercises.

Mantra - Greater Love

    You are loved
with a greater love
than anyone could
      ever imagine

... words in an email from Fred Rogers to Tom Junod, from Junod's article "What Would Mister Rogers Do?" (The Atlantic, December 2019):

... as a correspondent he was emotionally forthcoming and intimate, closing often with the assurance that he kept me in his thoughts and his prayers—"And, I guess you know, each morning I pray for you; I really do"—and sometimes with ministerial ardor. "You are loved with a greater love than anyone could ever imagine, Tom. I trust that you'll never ever forget that. ..."

Cryptomnesia

As defined in Wikipedia, Cryptomnesia "... occurs when a forgotten memory returns without its being recognized as such by the subject, who believes it is something new and original. It is a memory bias whereby a person may falsely recall generating a thought, an idea, a tune, a name, or a joke, not deliberately engaging in plagiarism but rather experiencing a memory as if it were a new inspiration."

The "Futility Closet" tells (29 Dec 2013)) of two famous literary examples:

Several years after publishing Treasure Island, Robert Louis Stevenson was abashed to discover that he had drawn much of the story from Washington Irving's 1824 book Tales of a Traveller, which he had read many years earlier and forgotten.

"I believe plagiarism was rarely carried farther," he wrote later. "The book flew up and struck me: Billy Bones, his chest, the company in the parlour, the whole inner spirit, and a good deal of the material detail of my first chapters ? all were there, all were the property of Washington Irving. But I had no guess of it then as I sat writing by the fireside, in what seemed the spring-tides of a somewhat pedestrian inspiration; nor yet day by day, after lunch, as I read aloud my morning's work to the family."

This is an instance of cryptomnesia, the mistaking of a forgotten memory for an original idea. Stevenson charged himself with plagiarism, but he had honestly believed he was writing a new story: "It seemed to me original as sin; it seemed to belong to me like my right eye." In reading Nietzsche's Thus Spake Zarathustra, Carl Jung was surprised to discover "almost word for word" an incident reported in a ship's log in 1686. Jung recognized the passage from a book published around 1835, about 50 years before Nietzsche was writing. He contacted the philosopher's sister, who confirmed that the two of them had read the book when Nietzsche was 11 years old.

"I think, from the context, it is inconceivable that Nietzsche had any idea that he was plagiarizing this story," Jung wrote. "I believe that fifty years later it had unexpectedly slipped into focus in his conscious mind."

... famous company for today's inadvertent mental glitches!

Individuation

A new-ish word from comrade B-ff's "Strengthsfinder" list of pop-psych talents is Individuation. The quasi-official definition, recast as "Individualization":

Your Individualization theme leads you to be intrigued by the unique qualities of each person. You are impatient with generalizations or "types" because you don't want to obscure what is special and distinct about each person. Instead, you focus on the differences between individuals.

You instinctively observe each person's style, each person's motivation, how each thinks, and how each builds relationships. You hear the one-of-a-kind stories in each person's life. This theme explains why you pick your friends just the right birthday gift, why you know that one person prefers praise in public and another detests it, and why you tailor your teaching style to accommodate one person's need to be shown and another's desire to "figure it out as I go."

Because you are such a keen observer of other people's strengths, you can draw out the best in each person. This Individualization theme also helps you build productive teams. While some search for the perfect team "structure" or "process," you know instinctively that the secret to great teams is casting by individual strengths so that everyone can do a lot of what they do well.

... sounds sweet, and of course is impossible to argue with. Who could be against empathy, insight, caring?

But contrariwise it might be fun to invert and describe "Individuation" in terms of its negatives — e.g., "you don't rise above the trees to see the forest", or "you pour vast amounts of time into one-off customizations that cannot scale", or "you fail to find evidence-based statistically-sound conclusions that apply across multiple cases". Hmmmm, that way it sounds like less of an astrology reading!

Mantra - Let Somebody Else Be the Hero

Omne Trium Perfectum

Latin for "All Threes are Perfect" — in writing, art, music (and countless other æsthetic and mnemonic endeavors) as per the Rule of Three. In Greek the "Hendiatris" is a triplet-based figure of speech, like the tricolon. And in politics/philosophy, a troika-triumvirate-tripartite arrangement seems to be an optimum combination of functionality, stability, and efficiency. Coincidence?

(should the Latin word be "Trinum" or "Trium"?; cf Toposes, Triples and Theories by Michael Barr and Charles Wells, There Are Three Points (2012-05-06), Big Ideas (2012-05-20), Think Better - Three Keys (2019-06-05), Three Things Tactic (2019-09-03), Creative Threes (2020-01-10), Clearly, Dearly, Nearly (2020-02-05), ...)

Stocks and Flows and Causal Loops

Simple stuff:

"Stock and Flow" and "Causal Loop" graphs look somewhat similar and are easily confused. Key to good understanding and Systems Thinking is to distinguish them and use each in its proper place. Economist Michal Kalecki joked that "Economics is the science of confusing stocks with flows." Don't do that!

There Is Nothing Wrong with You

From the idiosyncratic book There is Nothing Wrong with You:

  We are responsible
        for being
the person we've always wanted
        to find.

We must become our own best friend.

    We must learn
  to give to ourselves
        and
  to receive from ourselves
unconditional love and acceptance.

It is not selfish.
It is the first
GIANT STEP
toward
selfLESSness.
