.self: A new top-level domain designed to support self-hosting – The Human-Centered Computing Foundation (HCCF) announces its campaign to secure a .self TLD through ICANN’s Applicant Support Program, aiming to create an ethical, human-centered web architecture. The initiative focuses on reclaiming digital autonomy from big tech by enabling self-hosting and privacy-respecting services. Some commenters criticize the use of PDF format for the proposal, calling it ironic for a “human-centered” organization. The article outlines a vision for a TLD that resists data extraction and attention exploitation.
Free the Icons (290 points by zdw)
Free the Icons – Rogue Amoeba’s blog post argues that Apple should allow third-party app icons on macOS to have distinct shapes, rather than forcing a uniform squircle design. It critiques Apple’s “Liquid Glass” icons introduced in macOS 26 Tahoe, which were blurry and regressive, and praises improvements in macOS 27 Golden Gate but still calls for ending the shape prohibition. The author contends that unique icon shapes help users distinguish apps and restore visual diversity.
Memory Safe Context Switching (longjmp, setjmp) in Fil-C (51 points by modeless)
Memory Safe Context Switching (longjmp, setjmp) in Fil-C – Fil-C introduces memory-safe implementations of the setjmp/longjmp and ucontext APIs, preventing stack corruption and capability model violations. It explains the difficulty of making such context-switching operations safe, especially when saved contexts reference frames that may become invalid after function return or thread exit. The project targets C/C++ programs that rely on these APIs for exceptions, coroutines, and fibers, offering a robust solution for memory safety.

LongCat-2.0, a large-scale MoE model with 1.6T total and 48B Active – LongCat-2.0 is a massive mixture-of-experts (MoE) language model with 1.6 trillion total parameters and only 48 billion active per inference step. This architecture allows high capacity while keeping computational costs manageable. The model is positioned as a competitive open-source alternative for tasks requiring deep reasoning and long context.
Exploring PDP-1 Lisp (1960) (28 points by ozymandiax)
Exploring PDP-1 Lisp (1960) – A hands-on guide to the PDP-1 implementation of Lisp, created by 14-year-old Peter Deutsch in 1960. This version introduced the read–eval–print loop (REPL), the first interactive programming environment, transforming Lisp from a theoretical punch-card language into a practical tool. The article provides quick-start instructions and highlights the historical significance of this minimalist Lisp for early AI research.

Rocketlab acquires Iridium – Rocket Lab announces a historic deal to acquire Iridium, the satellite communications company. The acquisition creates a fully integrated space company combining launch services with a global satellite constellation. Financial and strategic details are not provided in the preview, but the move signals consolidation in the space industry.
Scientists find molecular-level evidence for two structures in liquid water (80 points by wglb)
Scientists find molecular-level evidence for two structures in liquid water – Researchers present new evidence at the molecular scale supporting the existence of two distinct structural arrangements in liquid water. This finding challenges the long-held view of water as a uniform fluid and could have implications for understanding its anomalous properties. The work uses advanced spectroscopic techniques to differentiate between high-density and low-density liquid forms.
Ornith-1.0: self-improving open-source models for agentic coding (172 points by danboarder)
Ornith-1.0: self-improving open-source models for agentic coding – Ornith-1.0 is a family of open-source coding agents available in sizes from 9B to 397B parameters (dense and MoE variants). It uses reinforcement learning to jointly optimize the code-generation scaffold and the solution rollouts, enabling the model to self-improve by discovering better search trajectories. The model achieves state-of-the-art performance on benchmarks like SWE-Bench and Terminal-Bench, and is MIT-licensed.
30-year sentence for transporting zines is a five-alarm fire for free speech (398 points by xrd)
30-year sentence for transporting zines is a five-alarm fire for free speech – Daniel Sanchez Estrada received a 30-year federal prison sentence for transporting a box of anarchist zines under the Trump administration’s counterterrorism memorandum (NSPM-7). The case marks the first prison sentences against alleged “antifa” under that framework, with eight defendants receiving a combined 450 years. The article argues this is a severe attack on free speech and political dissent, going far beyond typical prosecutions.
Local LLMs cross the usability threshold – The excitement around Qwen 3.6 27B and its “sweet spot” for local development signals that open-weight models have reached a point where they are genuinely useful as general AI assistants on consumer hardware. This trend accelerates the shift away from cloud-dependent AI, enabling privacy, offline use, and lower costs. Developers should invest in local inference infrastructure and model quantization techniques.
Mixture-of-Experts (MoE) becomes the dominant architecture for scaling – Both Qwen 3.6 (35B A3B) and LongCat-2.0 (1.6T total, 48B active) leverage MoE to balance capability and efficiency. This architecture allows models to grow to trillions of parameters while keeping per-token compute manageable. The implication is that future frontier models will increasingly adopt MoE, and practitioners need to learn routing, load balancing, and sparse inference optimization.
Self-improving AI agents through reinforcement learning – Ornith-1.0 explicitly uses RL to jointly optimize its coding scaffold and solution outputs, demonstrating a path toward autonomous model improvement. This “self-improving” paradigm could reduce reliance on human-labeled data and manual prompt engineering. Expect more frameworks that combine search, retrieval, and RL to create agents that learn from their own execution traces.
Open-source models are closing the gap on proprietary systems – Ornith-1.0 achieves state-of-the-art performance on coding benchmarks while being MIT-licensed, and LongCat-2.0 offers massive scale openly. The release of high-quality, permissively licensed models enables startups, researchers, and self-hosters to compete with big labs. A key actionable is to prioritize models that are both performant and legally unrestricted to avoid vendor lock-in.
Memory safety concerns in AI/ML infrastructure remain critical – The Fil-C project’s work on memory-safe context switching for C programs (used in many AI runtimes) highlights ongoing security and stability challenges. As AI systems grow in complexity, the underlying C/C++ codebases (e.g., PyTorch, LLVM, CUDA) need memory-safe implementations to prevent crashes and exploits. This trend may push more adoption of Rust or formal verification tools in AI engineering.
Historical AI/ML innovation cycles echo in modern tools – The PDP-1 Lisp article shows how early interactive programming (REPL) and symbolic AI laid foundations for today’s auto-regressive models. Recognizing that core concepts like recursion, symbolic reasoning, and REPL-driven development are being rediscovered in LLM agent loops (e.g., chain-of-thought, code interpreters) is valuable. Studying historical innovations can inform novel architectures for reasoning and interactivity.
Ethical and regulatory pressures are reshaping AI deployment – The .self TLD initiative and the harsh sentence in the zines case both reflect growing tensions around digital rights, censorship, and ownership. As AI models become capable of generating and distributing content, similar free-speech and surveillance issues will intensify. AI developers must design systems with privacy, transparency, and copyright considerations baked in, and engage with policy debates around algorithmic accountability.
