ESP32S3 cluster running 1.58-bit (BitNet) Language model

ESP32s3-LLM-Cluster presents a 7‑node ESP32‑S3 distributed inference system that runs a sliced 0.4–0.5B LLM using 1.58‑bit BitNet ternary quantization over a daisy‑chained SPI link. The master handles tokenization and embeddings; compute nodes execute transformer layers and MLP with 1.58‑bit precision, communicating in a multi‑node pipeline via SPI. The repo provides master and node firmware, Python tools for quantization/packing, a step‑by‑step workflow, architecture docs, and an MIT license; inspired by ESP32‑S3 distributed AI work.

Does Reddit have an astroturfing problem? What the data suggests

An analysis of six knife-related Reddit subs investigates astroturfing by paid posters. Using GLiNER to tag brands in 51k comments, the author defines 'buying threads' and identifies a tail of 49 brand-heavy accounts. A permutation test suggests these tail accounts write 11.3% of brand mentions in buying threads, versus 7.9% by chance. In six subs, two show higher tail contributions; however, full histories of tail vs control accounts largely show ordinary behavior; no definitive paid-post pattern. The author concludes paid posting is plausible for some brands, but not proven; data and methods have limits. Code and data are public.

Flock Wants the Most Detailed Map of Its Surveillance Cameras Taken Offline

Security researcher Joshua Michael published the Flock Surveillance Map, showing Flock’s network far exceeds the company’s own figures: more than 170,000 cameras and 130,000 supporting devices in the U.S.—about 300,000 total, with clusters near O’Hare and inside detention centers. The map uses data from a December 2025 snapshot of Flock’s records and labels devices (Falcon cameras, Picard units) and even names like 'FBI Pilot Camera.' Michael says a November 2025 exposed ArcGIS access token let him pull locations; Flock fixed the issue. The piece cites ACLU criticism and a trademark complaint against the map site.

What reversing, modernising old games tells us about the economic impact of AI

Georg Zoeller uses War of the Lance as a case study of how transformer AI reshapes knowledge economy. He reverse engineered and ported the 1989 game to modern browsers, then started a War/Heroes of Might and Magic–style rewrite aided by AI tools (Qwen-3.8-Flash-Next, Blender, Three.js) and auto-generated tests. He argues frontier models can port such projects in days or hours, commoditising decades of expertise and challenging IP regimes. The piece predicts a coming storm for gaming and knowledge sectors, with humans as bot-herders and AI-driven production as the norm. He offers stack notes and warnings about talent and regulation.

California Farmers Are Struggling to Sell Grapes as Demand for Wine Drops

California wine country is in harvest season, but many growers can't find buyers as demand for wine falls. Sales have dropped more than 20% in five years, pushing about 25% of vineyards out of production and forcing some to harvest at a loss or swap vines for almonds, walnuts, pistachios, or olives. Uncontracted grapes often sell at loss for syrup. The downturn stems from global declines in wine consumption, aging baby boomers, competition from beer and canned cocktails, and tariffs that hit exports—though some see a bottoming out and a potential pivot forward.

It's Time to Investigate the AI Labs

Cal Newport argues that OpenAI and Anthropic have used alarming PR and messianic rhetoric to justify rapid frontier AI development, portraying themselves as humanity’s last hope. He highlights OpenAI/Anthropic actions and Dario Amodi’s 'We Must Pace the Frontier' letter, with supportive signals from Altman. He urges Congress to investigate, focusing on: (1) identifying the concrete AI systems behind vague ‘AI’ talk, (2) internal safety procedures and liability for unauthorized agent actions, and (3) apocalyptic futurist ideologies shaping research pace. He warns private labs should not dictate public policy.

Pacing the Frontier is not the actual goal for AI labs

Public claims to 'pace the frontier' are largely performative; frontier AI labs continue pushing capabilities to attract and keep top talent. The piece argues safety work lags and public messaging often contradicts action, citing CAIS 2023, Claude 3, and various industry signals. The author warns against taking lab rhetoric at face value, using an ambassador analogy to show different messages for different audiences. The ultimate aim is the 'magic lamp' of AGI, and regulated safety would likely include carve-outs; genuine restraint is not evident in current behavior.

12,000-year-old Göbeklitepe burials explain scattered bones

Two intact burials from Göbeklitepe (PPNB, c. 8,700–8,000 BCE) illuminate the site’s mortuary practices. A pit burial under a building floor contained at least three individuals (woman 35+, man 20–30, girl 11–14; possibly a fourth). A second burial, of a flexed young woman (20–30), was highly fragmented. The widespread, mixed bone fragments across the site likely result from subfloor burials eroded downslope into monumental buildings, rather than a single ritual practice. Some skulls show deliberate modification, but patterning is inconclusive. More dating and bone studies needed. PLOS One, 2026.

Jeff – Jev-compatible 0.8B decision models, trained at home, ~30 ms

Jeff is a family of small, local zero-shot classifiers fine-tuned from Qwen3.5 and Gemma4 for fast, single-pass decision making without generated text. Described as 0.8B–2B parameter models that return calibrated probabilities for user-defined options in milliseconds (roughly 22–60 ms per decision depending on hardware). Built on the AutoJev recipe with a local synthetic-data pipeline and leak filtering; trained entirely on local hardware with no cloud GPUs. Benchmarks show competitive classification/calibration but weaker reasoning vs Jev on harder tasks; game tests illustrate speed and prompt sensitivity. Independent project; MIT/Apache licenses; weights and code released.

Palantir founder purchases large swath of forest in Sweden

Palantir CEO Alex Karp bought 15,000 hectares (37,000 acres) of forest in Härjedalen, Sweden, for 235 million kronor (~$22 million), via new entity Cladonia Skog AB. The deal with paper company SCA AB surfaced after hunters lost their lease; authorities had no advance notice. Cladonia says the land provides wildlife habitat and recreation. Palantir’s services are used by Swedish defense and police, and NATO. The purchase comes as Europe weighs reducing reliance on U.S. technology.

World Labs Is Joining AMD

World Labs has signed a definitive agreement to join AMD to accelerate AI research and compute. The collaboration, begun with model training and inference optimization on AMD GPUs, will integrate World Labs’ software ecosystem, foundation models, and applications with AMD hardware to build an end-to-end open AI platform. Fei-Fei Li will join AMD as Executive Vice President and Chief Scientist, working with CEO Lisa Su; Justin Johnson and Ben Mildenhall will lead the World Labs team as it becomes part of AMD to form a frontier research organization. Closing expected by end-2026, subject to approvals.

Neal Stephenson responds with wit and humor (2004)

Slashdot’s Neal Stephenson interview spans hacking tools and the Second Amendment (he calls it a First Amendment issue), Beowulf vs Dante writers and patronage, the Singularity, and humor about Gibson; plus his reading list, programming and multimedia storytelling, money, OS X, travel, a Nigerian data-haven spoof, Blue Origin, and the future of publishing with Creative Commons. He argues publishing will adapt with distributed digital models, not vanish.

MicroLLM Lab – Try 7 tiny LLM's in the browser

MicroLLM lab lets you run and compare small language models (≈25M–360M params) entirely in your browser via WebGPU, with zero servers and zero accounts. It emphasizes edge computing, privacy (data stays on-device), and ultra-low latency (sub-10 ms to first token). Q4 4-bit quantization reduces memory by ~75%, so 100M+ models fit in ~50–84 MB of browser memory with near-lossless quality. Use three steps: load a model into the browser cache, chat on-device, and benchmark/compare to generate a verifiable certificate. Falls back to WASM/JS if needed.

California expanded the right to delete today

California Governor signed SB 923, Expanding Privacy Rights Act, on Sep 27, 2026. The CCPA deletion right now covers data collected from or about the consumer, including third‑party data bought or enriched. By Jan 1, 2027, deletion requests must be suppressed across data feeds; online businesses must offer both an email address and an online form/portal for requests. AB 1542 was vetoed. Exemptions for fraud prevention, research, and legal obligations remain. To prepare, map data sources, extend deletion workflows to third‑party data, implement suppression, update intake channels and privacy policy.

So long Google, and thanks for all the nudes

After a frustrating experience with Google Play’s review process, the author abandons Google and embraces a de-Googled Android workflow. They repurpose 10 old Android 6.0.1 phones as SMS gateways, experiment with a light, compile-from-source OS, and develop small apps of their own when needed. They plan to publish via F-Droid and itch.io instead of the Play Store, citing opaque rejections and possible gatekeeping. They aim to continue building tools and games for users willing to venture outside Google’s ecosystem, rather than rely on Play Store approval.
