Ummm guys when we talk about memory access in theory can we just be rigorous and talk about the computational model? The real RAM model “in theory” tells me that memory access is O(1). Of course real RAM is a spherical cow but like we could

Yea experience is very useful (it is very hard to exert influence without power and be the tech lead of a team unless you have some corporate experience) but at some point one needs to realize that if someone was writing Haskell at the age

Python types - all the onus of static types, with none of the power of calculus of constructions. /s

sure of course one does not need types to do natural deduction… if you throw what you showed me to your average maths undergrad in the US they will get confused — I truly don’t see how proofs are simple

> How proofs work is really simple idgi. If you do your 101 logic class often you learn natural deduction, and how do you formalize natural deduction in a computer system? (Hint: type theory is "natural" for this). Also how pro

idgi tho. The average working mathematician seldomly thinks about proof theory or how proofs "work". Proof theory if must be put in a single box it is an logician's art, and at that point it is niche enough in both CS and mat

ZF(w or w/o C)/type theory/other foundations of maths are "equally" right? My argument is that even if we are trying to build PAs from scratch, type theory provides tangible benefits to the working mathematician bec

by runeblaze 1y ago
I mean sure we can do ZFC or ZF as the foundation, and I am sure with enough effort we can make metamath or some modern derivative great again. At some point though I like having years of type-directed program synthesis research helping me

That story reads like what happens when the average senior engineer tries to do a hardish usaco problem; turns out algorithm engineering is different from your average enterprise engineering; turns out there are people in both camps

The coin problem is like the intro to it. Try some of the codeforces one :skull:

Technically Koka checks your box. You also get algebraic effects in the same bundle

For these unfortunately you should dump most of the guide/docs into its context

Yep also people with differences in sexual development ("intersex", sometimes) are also overrepresented in trans people for obvious reasons. It is like extremely murky

I literally don't even write proofs in my head. Every time I write algo I just ask Cursor for a Lean/Rocq proof of correctness. No tests. No test coverage. The sheer power of type theory

Same here. Turns out writing too much code for RPG Maker XP when young ruins one’s perception of Ruby forever

I mean tbh industry research labs pump out a lot of good research due to them being intern projects (as in you have an army of passionate interns)

I mean we don't really talk about the accuracy of generative models. It is more of a discriminative model thing. But besides this, the current gen of models still, like, hallucinates more than many would like

It is weird to be honest. I first learned Coq and then started taking upper level maths classes. My group theory proofs were panned by my TAs as overly verbose, very precise, and I was specializing on H_1 and H_2s everywhere and having IHns

there kind of is, but also note we are talking about the exceptional talent here. I don’t think Meta is mass poaching the pure engineer types at OpenAI either

It has obvious pros, but since you asked about the cons —- anonymity brings the worst out of people; TC chasing leads to a reductionist view of people’s values and skills. For example unlike HN you don’t often do technical discussions on bl

I am sure as ideation devices these can work fine. I treat this more like basic infra. I would absolutely love the future where most phones have some small LLM built in, kind of like a base layer of infra

Tbh this is exactly how I felt in my algebraic geometry class. I still remember the fear I had when reading this from the blackboard Defn. f: X → Y is flat ⇔ O_{Y,f(x)} → O_{X,x} flat ∀ x. Then immediately I dropped that class. Tur

My opinion is that at least (safe, not spiro) anti-androgens should be able to be bought OTC. If some people want to place blockers on themselves they should be allowed to. I mean if you don't allow them to they DIY

Yeah like I very much respect their work, and there is some genuine beauty in having this policy such as "have access to > 100k USD in the last 365 days, this tier is for you" or the fact that they seem dedicated to also suppor

Yeah probably if they were writing a paper, encoding `.raw` files would have served them better (for being more convincing)

1. You are right 2. My guess: even among people who code professionally (e.g. data scientists), the same applies

To be honest I am pretty sure 95% of the people like play games and ride bike more than just coding.
