• Researchers say the approach could influence future alloy design across aerospace, energy, and other manufacturing sectors.

The Economics of Recursive Self-Improvement [pdf]

Key Points

• The paper analyzes when AI improving AI research could lead to self-sustaining acceleration in capabilities.
• It defines a core feedback loop linking current capability gains to improvements in the next generation of models.
• It argues that automated AI R&D alone does not guarantee an intelligence explosion because bottlenecks and diminishing returns may apply.

Show HN: MemStitch – Zero-copy context bridging for vLLM (25x TTFT speedup)

Key Points

• The article describes a cache-sharing gateway for multi-agent LLM workflows on shared long documents.
• It reports benchmark gains of 25.0x lower TTFT prefill latency and 43.4% fewer GPU cache blocks versus vLLM cold prefill.
• It provides local deployment instructions plus Python SDK and OpenAI-compatible API integration options.

Fundamentals of Wireless Communication

Key Points

• The textbook covers major wireless communication topics including MIMO, OFDM, CDMA, space-time coding, and opportunistic communication.
• It links theory to implementation using examples from real wireless systems such as GSM, IS-95, IS-856, Flash OFDM, and ArrayComm SDMA.
• The book is positioned for graduate engineering education and professional use, with instructor materials and a related short course available.

Is x86 ready to ACE it?

Key Points

• ACE is a new AMX-based x86 accelerator specification introduced by the x86 Ecosystem Advisory Group.
• ACE uses fixed-size tiles and outer-product instructions, while AMX TMUL uses configurable tiles and inner-product instructions.
• The article compares ACE with Arm SME/SME2, emphasizing differences in register storage size and vector-length design.

Satellite Tracker – Live Map of Starlink and 30k Satellites

Key Points

• The page is a live tracker for Starlink and approximately 30,000 satellites.
• Starlink is organized into multiple selectable shell categories.
• The interface includes a dedicated option to open a fuller Starlink view.

What will be left for us to work on?

Key Points

• The keynote argues that AI should be treated as a normal technology in the medium term unless a major discontinuity occurs.
• The article says no single AI lab milestone will suddenly eliminate jobs; workforce change will require adaptation over time.
• The speaker advocates building human skills that complement AI, while researching deployment-focused AI evaluation beyond benchmark scores.

Japan develops a method to recover up to 90% of lithium from used EV batteries

Key Points

• A Japan-based recycling method reportedly recovers about 90% of lithium from used EV batteries.
• The article says the process uses recovered lithium hydroxide instead of sodium hydroxide and could cut carbon emissions by about 40%.
• Scaling the impact will require better battery collection, since only about 14% of used lithium-ion batteries in Japan currently enter official recycling channels.

Agents.md – Dumb Human

Key Points

• The file tells an AI agent to distrust unverified user assumptions and inspect the repository first.
• It prioritizes simple, robust solutions and allows replacing poor proposed implementations.
• It requires validation through builds, tests, linters, and other checks instead of claiming unverified success.

Our Amish Language

Key Points

• The Libby Amish community was founded in 1992 in Montana with Pennsylvania Dutch as its main language.
• The community gradually modernized as members adopted cars, contemporary clothing, and more contact with non-Amish society.
• English use increased alongside Pennsylvania Dutch through church interaction, business, and shared media.

How to build a circular LCD clock

Key Points

• The clock is built with a 7-inch circular 1080 × 1080 LCD and a Raspberry Pi running Raspberry Pi OS.
• A Raspberry Pi 3B+ is said to be sufficient for simple animations, while a Raspberry Pi Zero 2 lacked enough RAM for a modern browser.
• The article explains setup details including VNC remote access, touchscreen gesture support, and hardware brightness and touch-rotation controls.

YouTrackDB is a general-use object-oriented graph database

Key Points

• JetBrains-backed YouTrackDB is described as a production-used object-oriented graph database.
• It supports TinkerPop, Gremlin, and a SQL-based graph query language called YQL, with GQL support in progress.
• The article includes practical setup paths for Docker, embedded Java use, and server deployment, with JDK 21 required.

Writing a bindless GPU abstraction layer

Key Points

• Loon GPU is an experimental abstraction layer inspired by “No Graphics API” and currently targets Vulkan 1.3 and Metal 4.
• Its API uses GPU pointers, bindless textures, and vertex pulling instead of traditional buffer objects, bind groups, and vertex buffers.
• The implementation still relies on backend-specific objects such as VkBuffer and MTLHeap, with future Vulkan extensions potentially simplifying pointer mapping.

Australia is offering free daytime electricity

Key Points

• The Solar Sharer Offer starts 1 July 2026 in NSW, South Australia, and South-East Queensland.
• Households need a smart meter and must opt in through their retailer to receive the free daytime electricity.
• The policy is intended to pass through the value of excess midday rooftop solar generation that depresses wholesale prices.
