The losing side of World War II was pretty nasty, including the third worst mass-murderer in history, but it’s amazing how many people seem to have forgotten that the winning side included the second-worst mass-murderer in history (who was an early supporter of the first-worst).

“You think Paul Graham, one of the most successful, most experienced investors in history, is secretly a midwit dilettante who coined ‘founder mode’ without knowing exactly what he was doing, and your plan is to try to dunk on this person? Good luck!”

Unless you are very unusual, everything you know about World War II comes from Allied historians and their intellectual descendants. This doesn’t mean the Axis powers weren’t the “bad guys”, but it does mean you should question everything you think you know about the “good guys”.

This is one reason why companies get paranoid about IP assignment paperwork, and draft that paperwork to be extremely comprehensive (often in ways which do not strike employees or advocates as being fair).

The Hawk Tuah girl has parlayed her 15 minutes of fame with such incredible skill that I’m beginning to think she’s an op.

The RPS discussion has served as an amazing honeypot for developers with no conception of the difference between returning a hello world json string and rendering a complete HTML page for an app like Basecamp to tell on themselves. Amazing resource for prospective employers 😄

Why do so many people struggle with higher math? One reason is that higher math textbooks & classes are typically not aligned with (and are often in direct opposition to) decades of research into the cognitive science of learning. Not saying that higher math would be “easy” if

The other day I saw someone say that the single greatest tool for improving metabolic health is the continuous glucose monitor. I have to disagree. There’s definitely utility in lowering excess carbohydrate intake. Most people eat too many carbs for the amount of hard physical

Not all conspiracy theories are true, of course, but any serious student of history knows that conspiracies are not the exception but the rule.

Hal Finney believed there was a good reason for bitcoin banks that could issue their own digital cash currency to exist. In this post, he paints a picture of a hyperbitcoinsed world with: - Paper bitcoin - Barely any self-custody - Fractional and fully reserved banks

A new study may explain the mysterious "Wow signal" from 1977. The bad news: nope, not aliens. The good news: something else very cool -- an enormous natural space laser! (Technically a space *maser*, but it's the same concept.) phl.upr.edu/wow/summary

I have reflected on, in the context of AI, what the subjective experience of encountering much stronger intelligence must be like. We all have some insight if we remember our early childhood! The experience is confusion and frustration. Our internal models predict the world
