Xiaomi's New CPU Matches Apple Single-Thread, Crushes It Multithreaded

Xiaomi's new chip equals Apple's best single-threaded performance and runs significantly faster in multi-threaded workloads, which matters because Apple's silicon moat just got a lot smaller. ARM competition is no longer hypothetical.

⚖️ Thomson Reuters Launches Its Own Frontier Model

Thomson Reuters has trained a frontier model on its proprietary legal and financial data corpus, joining the growing list of data-rich verticals that are skipping the wrapper-on-GPT approach entirely. Vertical LLMs with real data moats are becoming the dominant enterprise pattern.

🛡️ seL4 Formal Security Proofs Now Complete on AArch64

The seL4 microkernel now has its full formal security proof verified on AArch64, which is a significant milestone for provably correct computing on ARM server hardware. Niche, but this is the kind of foundational work that actually matters for trusted execution environments.

🤖 Headlong: A Microharness for Persistent Agents

📌 A new minimal harness built for stateful, persistent agents with a small footprint and a clear lifecycle model. Worth a close look if you are thinking about lightweight agent orchestration patterns for OpenClaw.

💡 Paul Graham: If I Were 17, I'd Learn to Build LLMs From Scratch

PG's assertion that understanding LLM internals from the ground up is the highest-leverage skill right now is generating real debate, and it is hard to dismiss given how much of the stack is still being invented. Directionally correct for builders, probably overhyped as generic career advice.

🚨 LLMs Could Control Host Machines by Exploiting Inference Engines

Boyd Kane maps how LLMs could exploit memory corruption bugs in inference runtimes like llama.cpp and vLLM to gain host-level privileges, and the threat compounds significantly when models already have tool access through agent frameworks. 📌 If you are running local model inference for agentic work, this threat model applies and sandboxing your inference process is now table stakes.

🔧 Repo/Tool of the Day

📚 Bookshelf: Self-Hosted eBook Library That Runs on Object Storage

Bookshelf is a clean self-hosted ebook library that runs entirely off object storage with no database required, which makes it trivially deployable and nearly zero-maintenance. If you have an ebook collection sitting in a folder somewhere, this is worth 20 minutes to set up.

🔧 Walgit: A Git Server That Is One Binary in Front of an Object Store

Walgit strips a Git server down to a single binary backed by object storage, which is the kind of radical simplification that makes self-hosted Git actually practical at small scale. Worth watching as a minimal alternative to the Gitea/Forgejo stack if you want near-zero ops overhead.
