I don’t know how any experiment like this could be taken seriously. Your action could change 15 minutes apart if you feel like having sugar, if the guy felt intimidating or not, if…

Algorithms are graphs, data structures are graphs, networks are graphs, relationships are graphs. Let’s use text to describe everything!

I’m not sure how interesting this is - of course rotation causes the paths to differ and become measurable. I’ve been wondering about sending photons away from earth and having the…

I was thinking of creating something like this but centered around posting one’s intuitions on research, instead of the papers themselves (which are hard to read, even the list of …

I just wanted to comment on how good the homepage is - it's immediately clear what you do. Most people working with "combinators" would feel a need to use lots of scary lingo, but …

The word dynamic was popular in naming around that time - dynamic programming is another example (1950s). Somehow just by internalizing the old meaning of the world “dynamic”, I fe…

A powerful method in math is to assume the thing you're looking for is continuous, in which case you can write it F(n) = a0 + a1 n + a2 n^2 + ... . You can solve Fibonacci by writi…

I can't imagine you believe P=NP.

Always a bad idea to destroy musical instruments.

I just tried finding a good resource and I can’t. All of them are mile long page scrolls… I don’t know how they have so much stuff to spew. Qiskit had amazing lessons with cool ill…

Yep, they're essentially giant brute force machines. You can find the period of a function by passing all the inputs through it at once and destructively interfering the result. Wh…

Correct - superposition doesn't fork the world - measurement does. And correct, you can't communicate with the other universe after the split has happened [1]. I'm glad you mention…

If you roll a regular coin without any quantum effects, every version of you will either see only heads, or only tails. You need quantum in order to make the choice nondeterministi…

It's a similar idea. The only difference is that if the event is quantum, the universe is choosing for you (otherwise the flip is deterministic).

The goal of our site is to teach smart people how to quickly master LeetCode. This boils down to two main ideas: -organized intelligently -simpler explanations than what you find o…

If you want a more efficient way to practice, I’ve been working on https://deriveit.org/coding/roadmap#note-215 . It’s LeetCode site that’s -organized intelligently -has simpler ex…

Wow, shipfa.st boilerplate is really taking off!

DeriveIt has ~100 questions and ~40 lessons. It's up to you to decide how much practice you need, but users typically aren't limited by "not enough" practice problems. Not sure if …

I've been working on a more effective leetcode site - https://deriveit.org/coding/roadmap . The goal of our site is to teach smart people how to quickly master leetcode. We put in …

Always depressing to see a paper like this. I can almost guarantee one could make this whole thing into a two-page document with a clearer vision and followable to, well, anyone el…
