Since gravity is the curvature of spacetime, quantizing gravity would mean quantizing spacetime (or quantizing geometry) also, which would lead to their being smallest units of space and time, perhaps somewhere around the Planck length and

Lying to local (and state?) police is legal (I think). Lying to federal LEOs is a crime.

The cost of Rust's abstractions are largely at compile time, not at runtime. For example, see https://idursun.com/posts/rust_zero_cost_abstractions_in_act... or https://carette.xyz/posts/zero_

This reminds me a bit of a Clojure library called Plumbing (formerly Graph): https://github.com/plumatic/plumbing . It also let you create a DAG for structured computation. It was used for a web service, at that time.

It wasn't a foreign agent being used for spying. It was software the government paid for.

Checkout Datomic. It’s a temporal database that uses datalog as it’s query language. There’s also Datascript, which does the same thing.

Research into belief perseverance shows that even when people are shown overwhelming evidence contradicting one of their beliefs that they dig in their heels and stick to the belief anyway. [1] There's also Frank Lunz's observatio

Libraries like this enable differentiable programming, which lets you backprop through more than just neural networks. For instance, people have built a differentiable raytracer and plugged a physics engine into reinforcement learning to ac

Rust can use reference counting though, in addition to borrow checking.

This is true for me also. It's much easier for me to make connections between things when I have information about them in my head already.

About a month ago, Open AI demoed a language model that does python code generation, using a natural language prompt. It was trained on Github repos. https://news.ycombinator.com/item?id=23250379

There were only two professors I was on a first name basis with in college. One was my advisor, I also worked in his lab for two years. The other was another professor in the department. It was different in grad school. It was first names f

I'm hoping the SwiftUI updates will include a TextView that can handle attributed strings.

> The current way to get a lot of efficient computation on a modern computer is to engage the GPU of said machine. This means that any language hosted on the CPU is going to be at a disadvantage. That's only true if your calculation

It seems like the author is wrong about the weak Sapir-Whorf hypothesis not applying to programming languages. This is anecdotal, but once I learned Clojure, some things about the way I thought about problems changed. I didn't think ab

Since TFHE does the encryption at the binary level, it looks like it would need to also work on the float level to be useful for a lot of data science/machine learning use cases. I could be wrong though.

I'd be surprised if it's dead. At least two of the people on the Swift for Tensorflow team were building a deep learning library in Swift before Swift for Tensorflow was a thing. Much of their work is a part of Swift for Tensorflo

I've not heard of Pointing and Calling before, but this perhaps explains what I do to keep from forgetting my wallet or phone when leaving the house. I pat my pockets before I exit and say "wallet" or "phone" as I p

It looks like the main differences are the bidirectional links and the automated creation of those links.
