Michael O. Rabin, co-recipient of the 1976 Turing Award and a giant in computer science, has died at 94. His foundational work on nondeterministic finite automata and the Miller-Rabin primality test fundamentally shaped the trajectory of computational complexity theory and modern public-key cryptography.

Rewriting Every Syscall in a Linux Binary at Load Time Instead of relying on ptrace or seccomp, this author built a hypervisor shim that replaces the 0F 05 syscall instruction with an INT3 trap right at load time. It’s a brilliantly unhinged but practical approach to sandboxing untrusted AI agent code with sub-microsecond overhead, gaining full execution control without a kernel module.

Family members of a two-year-old who was shot and killed in Federal Way are expressing outrage after a judge allowed the murder suspect to leave jail for a day to attend his mother’s funeral. Eighteen-year-old Jayson Jack is currently awaiting trial for the first-degree murder of toddler Synsyr Lewis, who was killed in an IHOP parking lot in April 2024.

Signal of the Day#

Figma’s implementation of the Model Context Protocol (MCP) demonstrates that reliable LLM-driven features require exposing strict, deterministic APIs for state extraction rather than relying on generative guessing. By injecting capture scripts to extract running DOM data and programmatically mapping it to native canvas layers, they solved the chronic fragility of code-to-design pipelines.

The US government is actively seeking access to Anthropic’s highly sophisticated ‘Mythos’ AI model to bolster its cybersecurity defenses, reflecting a frantic geopolitical race to harness AI for national security. Despite Anthropic currently battling the Trump administration in court, top officials recognize that ignoring the AI’s ability to autonomously identify and exploit zero-day vulnerabilities would be a massive strategic misstep.

The Chinese AI landscape is experiencing significant tremors as DeepSeek reportedly seeks its first external funding at a valuation of over $10 billion. Facing mounting compute costs and a fierce talent war that recently saw core contributors to its V3 model poached by Xiaomi and ByteDance, founder Liang Wenfeng is shifting the previously self-funded strategy to fuel the delayed V4 model.

Engineering & Dev#

The C++ ecosystem is gearing up for what is being called the most important update in a decade, as the C++26 standard draft is now complete. Led by Herb Sutter, the update introduces powerful reflection capabilities without runtime overhead, memory safety enhancements that have already prevented thousands of bugs at Google, and a new std::execution framework for concurrency. In the open-source AI sphere, Google has released the Gemma 4 model family under the Apache 2.0 license, featuring edge-friendly sizes and a 31B dense model that punches above its weight class with native multimodal and agentic workflows. Domestic AI developers are also pushing agent capabilities forward, with Zhipu launching a self-evolution mechanism for its AutoClaw agent to solve the common “amnesia” problem by learning from user corrections and persisting memory. On the security front, developers using Tiandy’s surveillance systems should note a critical Easy7 SQL injection vulnerability found in its REST API, which allows attackers to execute arbitrary SQL commands and potentially tamper with databases.

Tensions in the Middle East reached a new peak after the US Navy forcibly seized an Iranian-flagged cargo ship in the Gulf of Oman, blowing a hole in its engine room. The dramatic escalation prompted Iranian authorities to shut down the Strait of Hormuz to commercial shipping after a brief reopening, sending oil and gasoline prices surging and reviving broad global market volatility.

The weekend’s most consequential development is the rapid re-escalation of the U.S.-Iran conflict following a brief period of ceasefire optimism. The U.S. Navy fired upon and seized the Iranian-flagged cargo ship Touska in the Gulf of Oman, while Iran’s Revolutionary Guard attacked commercial vessels and reiterated its intent to restrict traffic in the Strait of Hormuz. The deteriorating situation has sidelined planned peace talks in Pakistan and threatens to severely disrupt global energy supply chains.

According to a cnbeta report, NVIDIA CEO Jensen Huang strongly criticized US AI chip export bans on China, calling the assumption that American companies will inevitably lose market share to local Chinese competitors a “loser mentality”. Huang argued that isolating China will force it to develop an entirely separate technology stack, fundamentally harming the global reach of the US tech ecosystem and warning that AI innovation should not be artificially fractured.

Zero-Copy GPU Inference from WebAssembly on Apple Silicon On Apple Silicon, you can share a WebAssembly module’s linear memory directly with the GPU—meaning zero copies, no serialization, and no intermediate buffers. By composing mmap, Metal buffers, and Wasmtime’s custom memory allocator, the author ran a 1B parameter Llama model entirely from a Wasm guest with zero-copy overhead. This is pure, hardware-sympathetic engineering, proving that sandboxed runtimes don’t have to ruin performance if you just leverage the underlying physics of the chip.
