For conventional fuel resources estimates vary from 670 years, to 160,000 years, and higher. For other reactors/elements, five billion years. Yes I know that number sounds insane: https://en.wikipedia.org/wiki/Nuclear_power#Conventional_fue...

When fusion arrives in the next 40 years: "Lithium from sea water would last 60 million years, however, and a more complicated fusion process using only deuterium would have fuel for 150 billion years." [calculated at 1995 global power output]

Any reason why you went with the "P"100 (resistant to oils) instead of the regular "N"100?

justQandA··on Ask HN: Have you picked up any new skill from scratch in your 40s or later?
Very cool. What DAW did you end up choosing? Did you stick with the first one you tried, or did you try several before picking?

This was amazingly helpful. Thank you!
justQandA··on Understanding Statistical Power and Significance Testing
This looks really neat but I unfortunately don't have the necessary background knowledge to understand what this is even visualizing. Is there a tutorial to help acquire the necessary math/background knowledge to be able to comprehend what's being modeled?

For example, what are "Power", "Alpha", "n", and "d"?

Also "Type I" and "Type II" errors? What's the intuition as to how these all relate each other?

Is there a blog post, chapter, that explains all of this? Or would this require significant learning i.e. a full semester course or a textbook.

This is an interesting angle.

Did you move from software development to sales?

Is this technical sales, "Sales engineer", or something different?

I'm curious how one transitions without any sales experience.

Does anyone know if the GeForce GTX 1650 SUPER, combined with a 3600x, is able to power a 4k monitor at 60hz?

Note: this is NOT for gaming. Just everyday workflow and dev environments in 4k, 60hz.
