[EN] Finance Education Considered... Dubious

I stumbled upon this comment about a month ago in a discussion about the big blackout on the Iberian Peninsula.
I can't verify it but it sounds uncomfortably plausible.

Quoting in full:

I am an ex-scientist and an engineer and had a look at the books of my son who studies finance in the best finance school in the world (I am saying this to highlight that he will be one of the perpetrators, possibly with influence, of this mess)

The things in there are crazy. There are whole blocks that are obvious but made to sound complicated. I spent some time on a graph just to realize that they ultimately talk about solving a set of two linear equations (middle school level).

Some pieces were not comprehensible because they did not make sense.

And then bam! A random differential equation and explanation as it was the answer to the universe. With an incorrect interpretation.

And then there are statistics that would make "sociology science" blush. Yes, they are so bad that even the, ahem, experts who do stats in sociology would be ashamed (no hate for sociology, everyone needs to eat, it is just that I was several times reviewer of thesises there and I have trauma afterwards).

The fact that finance works is because we have some kind of magical "local minimum of finance energy" from which the Trumps of this world somehow did not [manage] to break from (fingers crossed) by disrupting the world too much.

May 24, Day of Letters
celebrating Cyrillic writing,
used since the 9th century in Bulgaria
and later in Russia, Serbia and others.
_________
Pictured:
Cyrillic letters
A, Be, Ve,
Ghe, De,
Ie, Zhe
(Unicode: from U+0410).

The sequence of the first seven Cyrillic letters has stayed the same since the first version of the alphabet.
The two sequences of seven Bulgarian words above are, first, my modernization and, second, the beginning of the traditional mnemonic for memorizing the alphabet.

[EN] Struckly Typed; or, We Don't Need No Stinkin' Static Checks

A simple example.
Trivial, actually.
A multi-module Python program without type annotations.
Several classes used pervasively, each with an attribute foo_bar.
Rename the latter to baz_quux in exactly one of those classes.
So sift through many occurrences of foo_bar, figuring out which few of them become baz_quux.
No help from the compiler.

Not stringly-typed, but struckly-typed, to coin a portmanteau of "strong" and "duck"...
