d-Matrix presented Raptor 3D-DRAM, a compute-on-DRAM 3D-DRAM accelerator for generative inference at Hot Chips 2026. It addresses memory-bound decode in LLMs by stacking logic on DRAM dies; challenges include bank-channel mapping, I/O power, and thermal reliability, mitigated by stream-blocking, stream-flipping DBI, thermal-aware ECC, and bank chaining. Reported results: ~32.6 GB/s/mm2 vs 1.5 GB/s for HBM4; ~2.96 mW/GB/s (≈13.5x efficiency); ~100 TB/s bandwidth with 72 spare banks; 1 Hi 32GB card ≈1000 tokens/s for a 3T model with 1M context; scalable to multi-rack. Could reshape AI memory bandwidth vs capacity tradeoffs.

Pete Warden argues software engineering should face regulation akin to civil engineering due to safety and ethical risks from software and AI. Barriers include many self-taught engineers, global, iterative work, diffuse ownership, and a culture of speed. He proposes concrete steps: mandatory ethics training in CS degrees; a professional accreditation (e.g., through ACM); start with regulated sectors like health and transport; appoint a single project owner with veto power over safety; an anonymous safety-incident system similar to aviation’s ASRS; and a broad political push via industry coalitions to set norms before outsiders intervene.

Nick Poole chronicles building a directly heated vacuum diode for Make: Magazine, focusing on pinch-seal base fabrication using tungsten pins and nickel wiring, a glass flare, and careful heating to seal. The active elements are a tungsten filament and a nickel-formed plate coil, with a getter. After evacuating to ~10^-5 mbar, the tube is neck-sealed and the getter fired. The diode glows and tests, with Poole noting a destructive filament test for photos and plans to build a curve tracer.

Trump’s 2025 financial disclosure reports over $1.4 billion in crypto income and proceeds. Reuters’ broader estimate puts Trump family crypto profits at least $2.3 billion from mid-2024 to April 2026. A line‑by‑line reconstruction of the 2025 filing yields about $1.436 billion, split about 44% from CIC Digital licensing/crypto yield (~$636.1M) and 56% from World Liberty/DT Marks Defi and the stablecoin structure (~$799.5M). The article stresses this is income and proceeds, not personal wallet value, and explains differences in scope between the filing and Reuters’ family-profit estimate, plus governance details and conflicts questions.

Preston Byrne critiques Anthropic CEO Dario Amodei's essay advocating a global, regulated pacing of frontier AI. He outlines three elements: Embedded Evaluators (third-party verifiers inside teams); Democratic Coordination (coordinating safety standards via regulation, risking antitrust exemptions and First Amendment concerns); Global Coordination (harmonizing rules with allied and authoritarian states). Byrne warns such regimes resemble a censorship-industrial complex, citing the UK Online Safety Act and Ofcom’s SaSu case, showing regulators bow to political pressure. He argues US constitutional protections clash with speed limits on development and urges a swift, organized counter-movement against AI censorship agendas.

Pkgsrc is NetBSD’s package manager, portable to Linux, macOS, and Solaris; it can install binaries or build from source. It uses Makefiles for each package, downloads distfiles from various upstream sites, and is decentralized. Packages install under /usr/pkg by default (keeping the base system clean) and can run unprivileged in ~/pkg. It works on Debian too. The author uses it to install software locally without sudo and to build offline via a local distfile mirror; NASA reportedly uses it; more posts are planned.

OpenArch is a PyTorch-based collection of hand-written, readable implementations of modern open-source LLM architectures (Llama, Qwen, DeepSeek, Gemma, GPT-OSS, Kimi, etc.), inspired by Raschka's LLM Architecture Gallery. Each model lives in its own folder with model.py and a short README; the project prioritizes clarity over production speed. Models include GPT-2 XL, Llama 2/3, Mistral, Llama 4 Maverick, Qwen 3, Kimi K2, GLM 4.5, GPT-OSS, and more (some under construction). It invites contributions, shows repo layout, acknowledgments, and uses Apache 2.0 license.

Compression is prediction, but only after fixing the coding problem: what objects are represented, how they’re serialized, what the decoder and encoder share, and what operations are supported. In that setting, the ideal payload length under a model Q equals the cumulative log-loss. A code induces a distribution Q_C(x) ∝ 2^{-ℓ_C(x)} with S_C = sum 2^{-ℓ_C(x)} and ℓ_C(x) = -log2 Q_C(x) - log2 S_C. Conversely, a decoder’s prefixes define conditional distributions and KL penalties. If the source is unknown, empirical entropy H0 or higher-order Hk approximate the cost asymptotically. So: the equivalence holds within fixed framing, not universally.

Three reflections on the nature of dance. I) The foot as a surface shaping stability; underuse yields a line or point, so training aims to restore the surface. II) Learning differences and proprioception—clumsiness may be developmental or traumatic; teaching must address inner control and feedback, not just imitation. III) Connection—in partner work, a physicalist view prevails, using slow, granular analysis and emphasizing emotional openness and compatibility, while acknowledging great dances can come from unlikely pairings.

EuroBirdPortal offers live bird occurrence maps and a comprehensive species list, aggregating data from multiple portals (e.g., eBird, Tiira, Artportalen). LIVE maps cover the last 52 weeks with daily updates, though some portals update less frequently, leaving gaps in the most recent weeks. The viewer supports time modes (LIVE, calendar year, split year), a timeline, and data-availability indicators, along with notes on data validation and potential erroneous observations. A browser alert recommends updating to enable full features.

ScreenSize.net's Viewport Statistics Report presents anonymous aggregate viewport measurements from browser sessions, with description of methodology and privacy. Currently there is no reporting period and aggregate data is temporarily unavailable; the viewport tools continue to work. Data are collected per session and rounded into monthly buckets; no IP addresses, user IDs, precise timestamps, or full user-agent strings are stored, and Global Privacy Control/Do Not Track signals are honored. Measurements exclude viewports wider than 6,000 CSS pixels or taller than 4,000. Historical DPR values are normalized; device class is inferred locally. Audit shows zero raw samples.

bnb-side, a six-room B&B on Portland’s Isle, is fighting Airbnb’s bid to block its use of 'bnb' tied to the b-side festival. Airbnb says the branding could confuse customers and damage its brand; bnb-side says 'bnb' is just bed-and-breakfast shorthand. A ruling could force changes to signage and marketing and threaten the festival’s income, since the B&B accounts for about half of the festival’s £250,000 turnover. The case is ongoing; experts say "'bnb' is a common descriptive term," making a monopoly unlikely and possibly backfiring on Airbnb.

Calif researcher Lukas Maar outlines a generic OEM-specific root chain for unprivileged Android apps by exploiting a page-use-after-free in an OEM kernel driver, reached via an OEM sandbox escape if SELinux blocks direct access. The approach targets OEM code (Samsung, Xiaomi, Oppo/Realme/OnePlus) rather than generic Linux or chipset drivers, aiming for reliability, portability, and device coverage. Three chains cover Samsung flagships, much of Xiaomi's lineup, and recent Oppo/OnePlus/Realme flagships. Stage 1 escapes the sandbox; Stage 2 exploits the page UAF to gain kernel access. Defenses should gate such drivers behind SELinux and audit OEM IPC surfaces.

This post critiques three kinds of benchmarks—napkin-math style estimates, AI eval suites (DeepSWE, Senior SWE-Bench), and tire tests—arguing their numbers often mislead. Napkin-math uses latency-like labels for parallel memory/SSD operations, leading to single figures distorted by caching, OS tricks, and VM specifics. AI benchmarks suffer from small task sets, discontinuous scoring, and high grader variance, making results unrepresentative of real coding work. Disk benchmarks face similar issues; test code and hardware quirks skew results. The author concludes benchmarks are useful for intuition only when tied to derivation, context, and representative workloads, not memorized numbers. Appendix with expert commentary.
