Gram newton-schulz is based on the theorem that when $alpha > 1$, it is cheaper. for a typical muon application ($t=5, alpha = 4$), it saves 55% of the flops used by standard newton schul s with symmetric gemms, or 68% compared to an unsymmetric implementation. in the previous section, we showed that

What about OpenCL and CUDA C++ alternatives?

OpenCL, a GPU programming model, failed to become the dominant AI compute platform due to its slow committee-driven evolution, fragmentation, and inability to meet the evolving requirements of AI. Its failure highlights the importance of a reference implementation, rapid evolution, and avoiding fragmentation in achieving industry-wide adoption and unifying AI compute.

A new musical road on Route 66 in Springfield, Missouri, plays "America the Beautiful" when driven at 30 miles per hour. The road features 2,309 precisely placed thermoplastic strips that produce a 19.45-second rendition of the song.

How we run untrusted customer code at scale

Nango built a platform to run untrusted customer code securely, initially using a Node.js sandbox, then switching to AWS Lambda for better isolation. They now use Lambda with per-customer functions and periodic no-op invocations to keep functions warm, addressing security and performance trade-offs.

Claude Fable 5 is a Mythos-level model for ambitious coding projects, priced at $10 per million input tokens and $50 per million output tokens. It handles complex knowledge work with minimal oversight, including large migrations, complex implementations, and multi-day autonomous sessions.

A game's homemade crypto fell to a DIY supercomputer

https://www.ud2.rip/og/towerunite.png
A 509-bit RSA key in the Tower Unite game was factored using a weekend supercomputer and cado-nfs, allowing the decryption of the entire backend protocol. The game's developers, Pixeltail, replaced the homemade crypto with secp256k1 and libsodium in two weeks, but left server authentication vulnerable to an active man-in-the-middle attack.

Show HN: Open-source version of Anthropic's internal analytics engine

https://raw.githubusercontent.com/Kaelio/ktx/main/docs-site/public/images/ingestion-flow-transparent.svg
ktx is a self-improving context layer that teaches agents to query warehouses accurately. It learns from company knowledge, maps the data stack, and builds a semantic layer for agents like Claude Code.

A worm in my Erlang cluster, and adventures in microfluidics

The user is working on a project to create a tool that maps the topology of an Erlang cluster from a single node without shipping code to other nodes, and they have made progress in creating a pastable module that gives access to object code. The next steps involve implementing a graph traversal utility, tracking visited nodes, and shipping the probe module to each node in the cluster to ...

The Conductor Rewrite: What They Changed to Make It Fast

https://media.performance.dev/cdn-cgi/image/width=893,quality=100,format=auto,fit=scale-down/posts/p_XLCa4kktg-DT/6nEbe2vtQv2M.jpg
Conductor rebuilt its app from scratch to improve performance, focusing on local-first architecture, Tauri, and React optimizations. The team used profiling tools and libraries like TanStack Router and Virtuoso to identify and fix bottlenecks, resulting in significant speed gains.
