Ornith-1.5 extends Ornith-1.0's self-scaffolding into a self-improvement loop where the model generates tasks, builds task-specific scaffolds, and produces solution rollouts for reinforcement learning. It operates at 397B MoE, 35B MoE, and 9B dense, delivering state-of-the-art open-source performance on reasoning, coding, and agentic benchmarks, rivaling Claude Opus 4.8 on key tests. The training cycle has three stages: task proposal, scaffold construction, rollout, with rewards based on validity, frontier difficulty, and novelty. A harness and GRPO optimize the three stages jointly, creating a self-upgrading curriculum.

A study of 7,704 employees at a large healthcare organization found that fully remote workers reported the highest well-being, hybrid workers next, and onsite workers the lowest. Remote employees also reported similar or better perceptions of teamwork and inclusion, suggesting they feel connected. Turnover one year later was lower among those with higher well-being; location itself was not a strong turnover predictor. Autonomy and reduced daily stressors likely boost well-being, indicating flexibility is beneficial and in-person time remains valuable mainly for onboarding and relationship-building.

microGPT-C is a pure-C, dependency-free GPT implementation: a character‑level transformer with forward pass, backprop, Adam and sampling in a single C file requiring only libc. It trains on about 32k names in seconds and can generate new ones. Build with make run or run ./microgpt data/names.txt. It runs on macOS, Linux and Windows (MSYS2), with ARM64 NEON and x86‑64 AVX2 support. The model has 4192 parameters; trained on 20k of 32k+ names, achieving roughly 2.20 nats/char. Training/inference use separate forward passes; MIT licensed.

Notes on repairing a Nikon F100 film camera (for-parts repair). The author emphasizes scarce documentation and outlines a hands-on teardown, corrosion cleaning, and reassembly. Symptoms traced to battery corrosion caused dead/erratic operation; cleaning used distilled water and isopropyl alcohol, with grip and FPC protection. Missing parts are common (eyepiece, battery cartridge, focusing screen, film door), with fixes from eBay or 3D-printed parts. The guide highlights challenges like stripped screws and damaged screw bosses, recommending heat inserts and epoxy, and stresses meticulous screw management per the repair manual.

taffy is a high-performance, cross-platform UI layout library in Rust implementing CSS Block, Flexbox, and CSS Grid. It’s meant as a dependency for other UI/GUI libraries and currently powers Servo, Blitz, Bevy, Takumi, iocraft, Slint, and more. The README shows building a layout tree with TaffyTree, adding nodes with Style sizing, running compute_layout, and verifying results. It emphasizes faithful Flexbox/Grid specs, learning resources, benchmarks vs Yoga, and community contributions.

Moderna and Merck announced positive Phase 3 results for intismeran autogene, an individualized neoantigen mRNA therapy, in combination with KEYTRUDA, for completely resected stage IIB-IV melanoma. The trial met its primary endpoint of recurrence-free survival and a key secondary endpoint of distant metastasis-free survival, marking the first positive Phase 3 for an individualized neoantigen therapy and for an mRNA cancer therapy. Noubar Afeyan notes Moderna’s pioneering history, thanks the patients, and applauds the collaboration with Merck and investigators, while acknowledging more work ahead.

From a joke domain redirect in 2018, SondeHub grew from an amateur radiosonde tracker into a data platform that ingested, opened, and predicted balloon data. The author built reverse-predictions to estimate launch sites, mapped military vessels and sensitive installations, and drew increasing attention from government and military users, including the US Office of the Secretary of War, NTSB, and FAA, especially after the 2023 China spy balloon incident. Attempts to curb abuse included local predictors and AWS coordination. The project raised ethical and legal questions about data use and potential civilian/military misuse.

PostgreSQL is framed as the universal database: rock-solid, easy to install and scale, and extendable to cover many roles. The article argues you can replace Solr/Elastic for full-text search, MongoDB with JSON support, Kafka/RabbitMQ as a queue, Clickhouse with Timescale for time-series, and Redis for caching (using UNLOGGED tables). It also covers using LTREE for graphs, JSON APIs for microservices, and pgvector for AI/vector workloads via Timescale. Real-world validation comes from Contentful, Instacart, and others. The message: ask, can PostgreSQL do it before chasing new tech.

While implementing Knuth’s Algorithm D for long division, the author discovers a subtle D3–D4 bug: the trial quotient bound can fail when q̂ reaches or exceeds the base, due to a mismatch between TAOCP’s text, division definitions, and later errata. The smallest counterexample occurs at base 3: u=(1,2,0,0)3, v=(1,2,1)3. The bug lingered because the 1995 errata updated the text but not the theorems; LLVM’s APInt.cpp shows the same issue. A non-functional-change PR aligned the code with the corrected text; errata appeared 2026-06-09. The post also outlines faster/divisionless approaches and notes AI-finding attempts.

An OSINT writeup shows geolocating a tropical island resort from a drone photo using a geometry-based fingerprint and CUDA GPU search. It builds a 3-point fingerprint from three landmasses, then filters OpenStreetMap polygons to tropical, low-density clusters, generates triplets, and tests 80,690,777 triples in parallel. After deduplication, open-water and coral-cay shape checks, 213 candidates remain; NDVI vegetation and Copernicus DEM elevation checks shrink to a final set. Final results identify the resort as Oan, at 7°21′48.4″N 151°45′20.7″E (7.363444°, 151.755750°); camera facing NW.

WinV is a GNOME Shell extension that adds a local-only Win+V-like clipboard history to Ubuntu 26.04 (GNOME Shell 50, Wayland) without daemons, telemetry, or network services. It stores in-memory clipboard history for text and images (PNG/JPEG/WebP), with optional pinned items saved locally, and a private mode. Features include offline emoji/unicode pickers, keyboard navigation, pinning, editing, bounded history, and optional Super+V shortcut. History can be pasted back; selection can request Mutter to send Ctrl+V. No network usage; data remains on-device. Install via GitHub repo; MIT license.

Air Theremin is a mid-air musical controller with two input modes: HANDS and GYRO. HANDS uses a webcam to control volume (spread hands), pitch (raise hands), and silence (palms together); lean back for a mellower tone and keep hands in frame. GYRO uses a phone’s tilt to set volume (left-right) and pitch (forward-back); the range stays inside the frame, tilting outside cuts sound. If no camera or gyroscope, the mouse can drive it. Press START to calibrate. Created by Pavel Gurov; based on theremin.site.

An essay presenting activation energy as a general model for motivation and behavior. It argues that initial costs to start an action are higher than keeping it going, with analogies from neurons firing, static vs kinetic friction, and momentum in friendships. It applies the idea to conversations, exercise, and habit formation, suggesting small interventions (eg, cookies out of reach, visible exercise bike) to lower thresholds. It notes energy sources vary by person—introverts, hunger, and forward-looking goals—and urges mindful attention to activation-energy costs.

Ars Technica reports that under RFK Jr.’s tenure as HHS secretary, the Agency for Healthcare Research and Quality (AHRQ) faces collapse threats: ~75% of staff cut, about 150 grants canceled totaling over $250 million, and only a small portion of a $345 million 2026 appropriation spent ($15 million). Experts call the agency “on the brink” and worry it may not survive a second term. Thirty Democratic senators deem the moves “sabotage,” demanding rescission. The agency funds research on patient safety, care quality, rural health, autism screening, and reducing opioid reliance.
