Tony Hoare has died

Turing Award winner Tony Hoare (1934-2026), pioneer of quicksort and Hoare logic, has passed away at age 92. Beyond his foundational contributions to algorithms and formal verification, reflections on his career reveal a unique background in linguistics and a professional history spanning early Soviet computing to Microsoft. In his final years, he remained skeptical of "instant genius" tropes and enigmatically suggested that classified government technology far outpaces public advancements in hardware and cryptography.

Meta acquires Moltbook

Meta has acquired Moltbook, a social network designed for AI agents, and integrated its founders into Meta Superintelligence Labs (MSL). The platform provides a registry for verified agents to interact, coordinate complex tasks, and represent human owners in a "third space" for autonomous entities. This move follows OpenAI's recent open-sourcing of the related OpenClaw project and signals Meta's increased focus on agentic infrastructure and inter-agent communication.

Yann LeCun raises $1B to build AI that understands the physical world

Yann LeCun has raised $1 billion for his new startup, Advanced Machine Intelligence (AMI), to develop AI world models grounded in the physical world rather than just language. Challenging the industry consensus that scaling LLMs will lead to human-level intelligence, AMI focuses on building controllable systems with persistent memory and reasoning capabilities. The company intends to apply these models to industrial sectors like robotics and manufacturing while maintaining a commitment to open-source development.

PolyBlocks: A Compiler Infrastructure for AI Chips and Programming Frameworks

PolyBlocks is a modular MLIR-based compiler infrastructure designed to automate high-performance code generation for AI frameworks and hardware. It utilizes affine analysis and analytical cost models to implement optimizations such as multi-level tiling, fusion, and scratchpad management for operators like matmuls, convolutions, and attention layers. Evaluation on PyTorch and JAX shows that PolyBlocks matches or outperforms Torch Inductor and XLA, producing code competitive with hand-tuned vendor libraries on NVIDIA GPUs.

Isotopic Evidence for a Cold and Distant Origin of Interstellar Object 3I/Atlas

Isotopic analysis of interstellar comet 3I/ATLAS reveals a unique elemental composition, featuring water with a D/H ratio of (0.95 +- 0.06)%—over an order of magnitude higher than Solar System comets—and extreme 12C/13C ratios. These signatures suggest formation at $\lesssim30$ K in a metal-poor environment 10-12 billion years ago, providing direct evidence of ancient ice chemistry and volatile-rich planetesimal formation in the early Milky Way.

I built a public AI chat on my personal site, this is what I learned

Securing public LLM endpoints requires a defense-in-depth approach involving input sanitization of ChatML/instruction tokens, zero-trust system prompts, and strict output constraints. Key mitigations include Redis-based rate limiting, history role filtering, and hard budget caps to prevent adversarial cost spikes. The guide categorizes 16 prompt injection vectors—ranging from token injection to multilingual attacks—and provides an automated testing framework via a Claude Code skill for iterative red-teaming.
