Crush’s agentic fetch tool is cool: it reduces context for the main agent and becomes a whole mini web search situation ✦*⋆˚。⋆

first try of the new Cursor Composer model (btw I'm still a DAU of Cursor! @smol_ai is entirely a Cursor vibecode) one impressive example - Composer 1 finished 2 rounds of human feedback and debugging with me and got me what I wanted, while Sonnet 4.5 was still working on its…

yes Aether is a biglab model, no its not a llama one thing i learned from the inside is that all code ide model strings are combinations of models combined with prompts and toolcalls for the model. so no you wont feel like it is “raw” matching what youd find in the normal chat.…

{highly anticipated model} is coming sooner than all of you anons have been speculating. can try all 3 sizes now in @windsurf Next and see if you can figure it out :)

Copy-pasting PyTorch code is fast — using an AI coding model is even faster — but both skip the learning. That's why I asked my students to write by hand ✍️. 🔽 Download: byhand.ai/pytorch After the exercise, my students can understand what every line really does and…

There are plenty of valid things to critique about Rust but the anti-Rust takes I see on this site are so weird and lowbrow. Totally detached from what it's actually like to write Rust day-in day-out (and why it's been so successful).

The second point made by @eliasbareinboim is important. We rarely have a completely specified SCM on our hand. The purpose of Causal Analysis is the tell us whether the little we know about the SCM behind the data is sufficient for estimating our query of interest. Luckily, it…

Hi Boris, thank you for the note -- I’d just like to clarify two small points that often cause confusion. Regarding your first point, this is not rhetorical or anyone’s opinion -- it’s a proposition known as the Causal Hierarchy Theorem (CHT), first stated as Theorem 1 in the…

It's a while since my last YT video upload. Nothing is happening, I am busy working on the next one. Just taking longer than expected (been very busy recent weekends). Will be on connections between Riemann zeta and Brownian motion. ETA a few days to a week.

libghostty can now encode terminal contents as HTML. On the left is an example program that reads stdin, loads it in a terminal, and encodes to HTML. On the right, an example of `fastfetch` encoded to the browser. Coming soon to Ghostty clipboard ops automatically.

Two reasons why 0 × ∞ = 0 when doing measure theory 1) product of measures μ, ν μ×ν(A×B) = μ(A)ν(B) holds even when A or B have infinite measure 2) expected values/integrals: functions take infinite values (e.g., expected rolls to get a 6), but with zero probability, so cancel

0 × ∞ = 0 e.g., a line has width 0, length ∞, and area 0

My NixOS configurations for my dev VM setup are finally sanitized and open source. They work for both Intel and Apple Silicon. And I put together a video showing how I setup a new machine! Repo: github.com/mitchellh/nixo… Video: youtube.com/watch?v=ubDMLo…

Let X = exp(A²/2) and Y=exp(B²/2) where A,B are joint normal with mean 0, variance 1, and correlation ρ (between 0 and 1). Then, E[X|Y] = Y/ρ > Y E[Y|X] = X/ρ > X So X is greater than Y 'on average', and Y is greater than X on average. Here's a proof of that

Let X = exp(U²/2) and Y=exp(V²/2) where U,V are joint normal with mean 0, variance 1, and 50% correlation. Then, E[X|Y] = 2Y E[Y|X] = 2X They are each, on average, twice as big as the other!

The usual confusion about "reasoning" is the process vs. product confusion. In particular the following are both true --> LLMs/LRMs can correctly (and usefully) answer problems that would normally require "reasoning process" --> LLMs/LRMs don't necessarily use what might be…

Usually I am on team “current AI models are so smart, bro you have no idea”, but in this case I think @MLStreetTalk is right (echoing @GaryMarcus, @rao2z, etc.): current AI models *are* still oddly *weak* at “true reasoning” (in the sense of William James), compared to intuition.

.@GroqInc has introduced prompt caching for the SOTA open-source coding model, Kimi-k2. What does this mean for you? Significantly reduced costs with Kimi-k2 on its fastest provider. Check the price: left side without prompt caching, right side with prompt caching.

🚀 We just released Zed v0.200! In a previous release, we added the `--diff` flag to the Zed CLI. Now, you can compare two files directly from the project panel, via `Compare marked files`.
