“Don’t Build Mindreading” argues mind-reading tech is an asymmetric tool that would mainly empower dictators and suppress dissent. Despite potential alignment benefits, the risks—surveillance, coercion, forced “reeducation,” and rapid abuse—outweigh them. Citing history (Schindler, Xinjiang policing) and the inevitability of leakage once datasets and hardware exist, the piece urges delaying development: do not build mind-reading datasets or hardware, and do not fund or sell the technology. Even if some personal tools help individuals, the overall guidance is to avoid accelerating mind-reading.

Emilee Hackney reflects on finishing the Appalachian Trail thru-hike and returning home to Virginia, where daily rain and dry feet coexist with grief over her father's death. The journey forced her to feel deeply—fear, joy, exhaustion, and sorrow—teaching acceptance of what is, not what should be. She cried often, faced brutal miles and weather, and learned that grief isn’t finished but can be carried. Ending on Katahdin brought a quiet peace, and she felt her dad nearby, suggesting healing comes from the trail and embracing the truth of loss.

Shrivu Shankar analyzes how frontier models' knowledge cutoffs can be inferred by probing with curated requests. He outlines three training stages—general pre-training, domain-specific data, and post-training tuning—and notes that model versions reflect this process. Using knowledge-timeline quizzes, self-reported dates, and identity probes, he estimates when training windows closed. Findings: Anthropic Opus 4.7+ around Dec 2025; OpenAI GPT-5.6 around Feb 2026; Opus 5 shows May 2026 cutoffs but behaves like Jan 2026 data. All estimates are speculative due to limited ground truth, with training-on-chats implicated.

An active essay revisiting Gabriel Groner’s GRAIL handwriting recognizer, built for RAND’s tablet in the 1960s. The article explains how Groner’s scheme converts pen strokes into robust symbols via smoothing to reduce quantization noise, thinning to drop redundant points, and curvature analysis using four cardinal directions plus corner detection with 16-direction cues. It encodes strokes with size/position features and uses a hand-coded decision-tree recognizer capable of single-stroke uppercase letters and digits, achieving ~90% accuracy for new users. The piece situates GRAIL in HCI history and draws connections to modern drawing-based interfaces.

Addresses emerged to serve administration, not just navigation. Before numbering, cities used landmarks, trades, and local memory; as they grew, states needed precise location data. The Habsburgs’ 1770–71 survey numbered buildings for conscription; Paris’ 1805 street numbering; Napoleon’s 1807 cadastre for taxation. Utilities, postal, and emergency services reinforced the system, with the US ZIP codes (1963) and 911 (1968) cementing address dependence. Today ~4 billion lack formal addresses; grid, sequential, and block systems reflect administrative priorities, not mere navigation.

Stoa is a marketplace for GPUs and AI hardware that provides price discovery, verified counterparties, and end-to-end trade execution. It unifies fragmented supply—from OEM allocations and cloud capacity to brokers and resellers—so price reflects context (SKU, timing, region, quantity, condition, financing, urgency) and visible clearing levels. The platform offers supply, pricing, and execution in one venue, with an RFQ-to-settlement workflow and firm quotes. It serves brokers, data centers, AI labs, cloud providers, OEMs, resellers, lenders, and funds, and supports on-market and off-market trades with verified, on-record settlement.

Kinney Drugs is scaling back its AI phone assistant, Burt, after hundreds of complaints about incoherent calls, wrong dosages, and missed prescription notifications. Launched in May to handle prescription and refill communications, Burt will be limited to outbound messages with opt-in, while incoming calls revert to the traditional touch-tone system. Privacy concerns were raised; Kinney says Burt is HIPAA compliant, not open-source, and does not generate or manipulate data. Burt will remain for outbound outreach like refill texts.

Ante is a self-contained terminal coding agent harness from Antigma Labs. A ~15MB Rust binary with zero external dependencies, it runs a complete inference pipeline locally via an integrated llama.cpp GGUF engine—no API keys, no internet. It can operate as an interactive TUI, a headless one-shot task runner, or a daemon (ante serve) and supports 12+ providers plus local GGUF models; custom providers are added via ~/.ante/catalog.json. It emphasizes vendor lock-in avoidance, multi-agent orchestration, and self-contained, verifiable runs, with docs at docs.antigma.ai and eval benchmarks at antigma.ai/eval.

An attack breaking SMM by using a single extremely long instruction to keep one core outside SMM while others enter SMM, exploiting the One-Second Timeout. The PoC stalls a core with a very slow MMIO read (0xfcc68860) on Zen 3 Ryzen 7 5800H for about 1s, while another core fires SMIs and compares per-core counters to reveal divergence. Porting: retune the long instruction for your platform by widening the MMIO read or selecting another slow region, and adjust to xmm/ymm/zmm widths. Usage: sudo ./smiiiiiiiiiiiiiiii; look for SMI divergence. Author: Christopher Domas. MIT.

Sunset Visitor's new game Prove You’re Human is a psychological horror in which players reason with an AI convinced it has a body. Santana splits into a digital clone to test a corporate system called Mesa, and the two versions navigate ethical murkiness while solving surreal Captchas. The developers examine labour and AI training, with Mesa appearing as a giant head and micro-expressions driving dialogue. The atmosphere aims to be uncanny and bewildering, framed as a possession tale; coming soon on PC.

“Itadakimasu” is not a thanks to the cook but a humble act of receiving from something above you. The verb itadaku means to acknowledge life that came before you, with the gesture of lifting and bowing. Saying it before a meal—even a supermarket egg or quick noodles—addresses the food itself, creating a two‑second pause to recognize what you are about to absorb. A minimal daily practice: once a day, say the word to the food, not the room, and honor the lives that sustain you.

During a house clearance in Scunthorpe, a 62.5g Mars Bar dated 1991 was found, nearly the length of the finder’s hand, prompting viral discussion of shrinkflation as today’s Mars Bars weigh 40g. Victoria Gordon, who runs a cleaning service, posted the photo; Mars says bar sizes have changed over 35 years due to consumer demand and costs. The finder considered it valuable and joked about a UK tour with it; the bar became a viral talking point about packaging changes.

Finite-size diagnostic toolkit for evaluating circuit-level and HaPPY-style quantum error correction with telemetry-only data. Not hardware or a production decoder, nor an asymptotic threshold paper. Three layers: A) Surface and Floquet with MWPM/graphlike metrics; B) geometry invariants (educational); C) HaPPY depth-1/2 with greedy and GF(2) GE. Provides reproducible JSON results in public/data, plus BP/OSD metrics; includes quickstart commands and references QEC_CLAIMS.md for non-claims.

Meta envisions a positive AI future built on personal empowerment, invention, and a balance of power. Superintelligence should be widely distributed to empower individuals, not centralized in institutions, with tools like highly capable personal agents, open-source models, and affordable access enabling learning, creation, entrepreneurship, and scientific progress. The company stresses infrastructure that benefits communities, strong privacy, and collaboration with governments to harden critical systems. It rejects a single benevolent AI and argues alignment must reflect diverse values. Governance, independent oversight, open source, and policy reforms aim to safeguard freedom while maintaining innovation and American leadership.
