It is a summary of a rather well known book of the same title.

Thanks. I know the book.

That’s not a summary. To me at least.

It says “Outline and Study Guide” near the top. So I guess it’s the Cliff’s Notes version.

Thanks, I didn’t see that. Not sure, how useful this is for a student.

I don't know for a student but given the density of the primary text (okay, I read that long ago, but that's what I remember anyways) it seems to me to be a pretty good condensate.

See this [1] article by Martin Fowler. UML promised and pushed for more control over how much of the program it could sketch/model.

I'm missing "UML as a satelite map of the wilderness"

It depends on how many decimal places you are printing

    >>> f'{b:.54f}'
    0.299999999999999988897769753748434595763683319091796875
    >>> f'{x:.16g}'
    0.3
    >>> f'{x:.17g}'
    0.29999999999999999

Plotnine uses other packages in the scientific Python ecosystem. That is probably where the abbreviations that irk you come from. In some cases those "abbreviations" have roots 20 years deep!

There is geothermal energy if it has a molten core.

An interesting note is, the footprints where formed on the supercontinent Pangea.

I think it would be helpful for discourse if you read the article in full.

"One of history’s fews iron laws is that luxuries tend to become necessities and to spawn new obligations." Sapiens, By Yuval Noah Harari

This quote stood out for me when I read Sapiens.

It's a little strange to use the phrases "tend to" and "iron law" in the same sentence.

> It's a little strange to use the phrases "tend to" and "iron law" in the same sentence.

Not really. Tendency denotes a general inclination, such as objects tending to move toward the centre of mass. Tectonic plates tend to shift slowly. In both cases these are very solid and reliable predictions which are almost certainly true in a vast majority of cases.

I would not agree with the statement vis-a-vis luxury items and necessity (fur coats, diamond rings, harems, are not demanded by all), but there is a tendency for certain classes of items to be considered "essential" over time.

With a sufficiently hot take, iron laws become malleable.

May be strange at a first glance but binary/boolean logic/reasoning/quantification is just a special case of probability theory. This is covered exhaustively in Probability Theory: The Logic Science, by E.T Jaynes.

And so "tend" and "iron law" are interpreted as assertions of different levels of certainty, where "tend" implies a certainty greater than 50% and "iron law" a certainty closer to 100%.

A tendency can be shown to be present in all known categories of samples (justifying 'Iron') , while not occuring in every single sample, making it a tendency.

Separately, tendency can mean a type of outcome is more likely, or that there is an underlying force acting in a direction, regardless of whether that force is cancelled by other forces.

Gravity is a tendency for things to fall back to earth. But somethings can escape it.

Huh I wonder what he would have said about access to clean air, water, and land.

What context is this in? Some people who are religious break this rule. The amish aswell are an extreme example.

Given that Chroloquine has been around for a long time and that it is well studied, is there any merit to assume that using it was not a random idea and that it works against some other known RNA viruses?

Apparently the possible utility of chloroquine was discovered because SLE patients on it in China weren't getting Covid-19 during the outbreak [0].

It is know to be a zinc ionophore so I would not call it random. That said, it is known to have some side effects. [1] My concern around its use is that it requires a prescription. People won't likely be using this until a doctor prescribes it. By the time a person has gone to a doctor, the virus has likely already replicated quite extensively. Zinc ionophores would be most beneficial if taken very early on after initial infection.

Chloroquine was discovered effective against SARS-coronavirus following the 2003 outbreak.

It is not straight forward but look into the Second-Digit Benford's Law (2BL-test).
