There is this new and very promising package that adds interactivity to plotnine graphs https://y-sunflower.github.io/ninejs/.

Sorry for the confusion. Though, it is a mango tree in a mango garden! The continued development and maintenance of plotnine is supported by Posit, PBC, the same company behind the Tidyverse.

If you already use plotnine, or if this has piqued your interest, the next release (v0.16.0) will bring nice capabilities.

You can get a sneak peek by installing the pre-release:

pip install --pre plotnine

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

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

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.

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%.

"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.

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?

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

I have been through this path of trying to figure out why pandas Groupby is slow. It is a big bottleneck when building packages on top of pandas.

Water is a good insulator, but not a perfect insulator. If the temperature difference between the bottom and top changes so does the heat transfer and given time the effects will spread. But most important is, warm water/moisture is less dense than cooler water, that means large heat transfer by convection currents in addition to the low conduction (inverse of insulation).

Good curiosity, but they would have to put out atleast an equal amount of heat into the atmosphere! (2nd law of thermodynamics).

has2k1 — Thu, 09 Jan 2020 00:20:53 +0000

It seems unethical if you do it by gene drive. But what if you add some natural randomness to the process and other desirable objectives. Imagine a dating service with a DNA database and you can match up people whose offspring could potentially be very subservient.

What if the full effect is expected after matching 5 generations of people?

What if the real goal is to create a fraction of people more attentive to minding about the environment and total blissful subservience is just a bi-product? For the good of the human race!

Thank you, very interesting geography. Any theories on how the river broke through the mountain range, i.e. the timeline for the erosion?

From my speculative chair, it looks like the river existed before the ranges.
