We’re opening a research preview of Claude Duet, a new app where Claude works as a proactive agent. It comes to you with what needs your attention, completes tasks you ask of it, keeps working when you step away, and checks with you before it acts on your behalf.

Hardware looks scary until you break it down into small steps. So I built an app that takes you through Arduino one circuit at a time. Made with Opus 5.5 learn-arduino-red.vercel.app

我女朋友问我天天抱着手机干啥 我说我在创业 她问创啥业 我说：涨粉，目标50万曝光 她说：那不就是玩手机吗 我说：你不懂，这叫内容创业 她说：哦，那一个月赚多少 我说：目前还在投入阶段😭

un tipo vibecodeó su TV con Claude y le sacó todo el bloatware y los anuncios... recreó la interfaz inspirada en Apple TV de 282 MB a 96 MB de RAM. 3x más rápida. cero anuncios recomendaciones de pelis, clima, precios de crypto y se oscurece sola al atardecer el repo está abierto y funciona en Google TV, LG y Samsung te lo dejo en comentarios

Lands tomorrow before 10am PST.

Gemini 4 Argon combined three open-source datasets to build an interactive 3D visualization of human anatomy. Toggle different layers in motion, isolate muscles, or zoom inside a beating heart.

Pro tip for Rust on Linux: give your build cache its own drive. I moved mine to a second NVMe (TLC with DRAM, XFS, no compression), and my desktop no longer freezes when agents run builds in parallel. Builds go through mbx by @jdxcode, so every worktree shares one cache.

Over the past year, the Discovery team at @GoogleDeepMind, in a project led by student researcher @dsantosmarco, has made new discoveries in one of the most beautiful open problems at the edge of computation: Finding the 6th Busy Beaver (BB) number. While most AI math systems solve human-generated problems, like theorems, this work tackles a different aspect of mathematical creativity: Discovering hidden problems. For years, the BB Community has pursued one of theoretical computer science’s most captivating collaborative quests: finding the simplest programs that run the longest before halting. Because determining whether these programs ever stop is uncomputable, no universal algorithm can solve it, meaning new mathematical techniques need to be found and invented to make progress. In this way, the BB challenge serves as an open ended domain for mathematical creativity and, in particular, a generator of hard math problems called Cryptids. These are tiny programs whose halting behavior is governed by and equivalent to deep, unsolved math problems in number theory, similar to the Collatz or Goldbach conjectures. Historically, the BB community had recognized ~20 Cryptids in BB(6), and the best problems were selected for the Busy Math Olympiad (BMO). Building on their work, Marco built a pipeline powered by Gemini 4 Argon that: 1️⃣ Simulates raw Turing machine traces to compress recurring patterns. 2️⃣ Conjectures mathematical transition rules & runs synthetic experiments to test edge cases. 3️⃣ Proves the equivalence formally in Lean 4.

Using this pipeline, Marco and the team discovered 20 new potential Cryptids and verified 33 more machines previously studied in the BB community. All the proofs were open sourced and shared in the community discord channel and we hope that they will help the community to make progress towards resolving BB(6). We also contributed related halting/non-halting proofs directly to the community GitHub repository. Finding these Cryptids shows hidden links between simple programs and number theory, and helps mathematicians map the limits of computation. I'm also excited about Gemini 4 Argon's ability to help researchers both solve hard problems and accelerate scientific discoveries, of which Busy Beaver is just one example. Work led by our student researcher @dsantosmarco with paper contributions from @vivek_veeriah, @Dahoas1 , Andrew Bolt, @zuza777 , Satinder Singh, and myself with additional contributions from Hussain Masoom, @maxencefaldor , @MoritzFirsching and Petar Sirkovic.

Today at Resend Forward, we're introducing two new products. ▪️ Inboxes: shared inboxes for agents and humans ▪️ Forge: Resend's new sending infrastructure, fully controlled by us Here's what's new 👇

As traffic grew exponentially, we moved 99.99999% of GitHub's Git repos to Azure. A new write path moves the last, busiest repos, keeps cross-region round trips from capping throughput, and enables stateless Azure Blob Storage replicas.
