The Ledger

Every statement that passed quotation and attribution checks. Mix any filter with any other: certainty 1/5, debate potential 5/5, or both at once.

clear all ✕

why aren't all 10 resolved? a statement only gets an assessment when the public record can support or contradict it. opinions and what-ifs never can, and 1 checkable ones are still open, waiting for their date. predictions held up or didn't; assertions are supported or contradicted. on every card: ▮▮▮▮▮ certainty · ▮▮▮▮▮ debate potential. speakers are clickable

Hong: Lean and Rust yield superior reinforcement learning convergence over Python
“If you want proof to be informal math, It's very annoying, because then that's, like, just makes objective function. Your code is something like Python, your proof is, say, natural language, math proof. You will not have very strong RL kind of performance, rig…”

Lattner says Mojo is 10,000x faster than Python and beats Rust
“Mojo is not just a little faster than Python, it's faster than Rust. So it's like tens of thousands of times faster than Python, and it's in the Python family.”

Fredrikson: Formal software verification takes 10 to 20 times longer than Python
“The reason people don't do it is that it's not easy and it's not fun, right? It takes you like 10 or 20 times as long to like fight with the type checker, which is essentially like proving that you don't have a vulnerability as if, as it would if you just like…”

Colvin: Rust-native data storage could yield 3x to 5x Pydantic speedup
“We have plans to move some of the, basically store the data in rust types after validation. Not convert to Python types. So then if you were doing like validation and then serialization, you would never have to go via a Python type. We reckon that can give us …”

Zach Lloyd: Warp relies on over one million lines of Rust code
“Warp is over a million lines of Rust code, and this is like, up until very recently, this type of agentic stuff just did not work in Warp because it's not built on any public UI framework, like we have our own internal UI framework, and so it really needs to u…”
