I really disliked the book. Probably one of the worst books I’ve ever read.

Some times HN shows well-written and researched blog pieces about events or characters in scientific history. This book felt like the author read a bunch of these and put them together in a book. Then the reality-fantasy aspect of it makes no sense to me.

Why did you like it?

Re:Julia 1.10 Released on Wednesday December 27, 2023 @04:43PM (#38787118)
I think it’s also the design philosophy. JuMP and ForwardDiff are great success stories and are packages very light on dependencies. I like those.

The DiffEq library seems to pull you towards the SciML ecosystem and that might not be agreeable to everyone.

For instance a known Julia project that simulates diff equations seems to have implemented their own solver

One of the things I don't like about the Julia ecosystem is the monolithic libraries that have tons of dependencies. DiffEq is one of those. I think its fine to write a script but if you want to develop something more sophisticated, you want to keep your dependencies lean.

Im not sure if Julia will ever take off. Right now there are huge investments in the AI space and Julia has no presence in those.

I’m sure this question has been asked plenty of times but what is the best place to start with LLMs (no theory, just installing them locally, fine tuning them, etc)
Is this bad for research?

That part about Gibson doing a documentary is not true. Just Google it.
Publishing is a social activity. And, today, a bad metric to measure research success. It has been hijacked by careerists and mafiosi.

Eropple,

Funny that you cite las Casas as a historical document, when it is well known that his writings were exaggerations

https://en.wikipedia.org/wiki/A_Short_Account_of_the_Destruc...

Re:Inca Child Sacrifice Victims Were Drugged on Saturday October 22, 2022 @04:22PM (#33301842)
There was no genocide of native civilizations.

Its unfortunate that poor historical revisionism is employed in the USA for political purposes and that this becomes the baseline of historical knowledge of the average citizen.

It is one thing to analyze the colonization process outside an Eurocentric perspective (e.g., Conrad's critique of British colonialism in Heart of Darkness). Another is to create a caricature of barbarian Conquerors raping and murdering an entire civilization (or, as the protestant press of the day used to print, eating babies alive).

Genocide is "the deliberate killing of a large number of people from a particular nation or ethnic group with the aim of destroying that nation or group". Compare this with https://en.wikipedia.org/wiki/New_Laws

Re:Inca Child Sacrifice Victims Were Drugged on Saturday October 22, 2022 @04:09PM (#33301724)
Hi again :). We both have an axe to grind.

I was just giving some support to the parent comment about the scale of sacrifices compared with the Spanish inquisition.

Even if the number is 4000, its still quite comparable with the number of executions of the Spanish inquisition over 3 centuries.

About [1], yes, I do not dispute that. But we were comparing different systems and that the Aztec system was much more cruel from a modern standard.

Re:Inca Child Sacrifice Victims Were Drugged on Saturday October 22, 2022 @04:01PM (#33301634)
According to Wikipedia. Spanish Inquisition executed between 3000 and 5000 people over 3 centuries: https://en.m.wikipedia.org/wiki/Spanish_Inquisition

According to this article. “When the Great Pyramid of Tenochtitlan was consecrated in 1487 the Aztecs recorded that 84,000 people were slaughtered in four days”

https://qz.com/374994/aztec-sacrifice-was-real-and-its-not-f...

So, the math checks out.

I do not have nice food at home.

> The "water" moves near light speed effectively

This is not how the hydraulic analogy works. The "speed" of the water is irrelevant. The analogy is used to understand losses, energy balance, energy conservation, reactive power, etc.

The hydraulic analogy is very sound.

Re:Is the smart grid all hot air? on Sunday July 10, 2022 @06:08PM (#32049587)
The water analogy is perfectly fine to use to talk about the bulk AC transmission grid (which is low-frequency alternating current).

photochemsyn speaks about how the hydraulic phenomena is not adequate to describe some electronic aspects (e.g., modeling p-n silicon junctions). These issues are irrelevant to how well the hydraulic analogy works to describe the workings of the AC transmission grid.

Re:Is the smart grid all hot air? on Sunday July 10, 2022 @05:57PM (#32049503)
A load being inductive, capacitive, or reactive has to do with its impedance, which is a concept related to the steady-state analysis of AC networks.

The hydraulic analogy easily extends here - just imagine water flowing back and forth.

This is well studied [1] and power engineering books make use of this analogy.
