Kastor is a declarative language and toolchain for AI agents. It defines agents, tools, and prompts in HCL (.agent, .tool, .prompt) and a Go-based workflow with two paths: kastor build (generates runnable projects for target frameworks) and kastor plan/apply (reconciles long‑lived agents on hosted platforms with state, diffs, and drift detection). It’s an early PoC; current work parses specs, validates references, and generates LangGraph projects (e.g., weather agent). Planned: local state drift and AWS/Azure deployment. Install via Homebrew or install script; SPEC.md is the design source.

Chatto is now Open Source and self-hostable. Quick start via Homebrew or binaries for Linux (x86_64/ARM64), macOS, and Windows. It prioritizes privacy: data at rest encrypted with per-user keys, no federated data or third‑party tracking; each server runs a single community and clients can connect to multiple servers. It includes built‑in voice/video with end‑to‑end encrypted calls. Chatto Cloud will enter public beta in Europe with auto‑scaling, nightly backups, and no lock‑in. Version 0.4 with 1.0 expected in 6–12 months; feedback via the community.

The Atlantic examines a looming 'postliterate' era in which reading declines despite technology abundance. Tracing history from Alexandria to Gutenberg to TV and the internet, it shows Americans read less for pleasure, news, and deep analysis, while exposure to short-form content dulls attention and harms comprehension. Education pushes for excerpts; students struggle with longer texts; cognitive research links reduced reading to weaker reasoning. The piece argues the rise of AI and social media heightens risk to thought, while a committed minority keeps reading as a civic and cultural anchor. The future of literacy hangs in the balance.

CVE-2026-57589: OpenBSD up to 7.9 has a use-after-free in sys/kern/sysv_sem.c enabling local privilege escalation to root via a context-switch use-after-free after tsleep in sys_semget. CVSS v3.1 base score 7.4 HIGH (AV:L/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H). Affected: OpenBSD versions up to 7.9.

Cloudflare's Meerkat is an experimental global consensus service to manage control-plane state across 330+ data centers. It uses QuePaxa, a non-leader, majority-quorum consensus that allows writes from any replica and avoids leader failures that block writes in Raft. Meerkat maintains a common log of events; decided slots ensure linearizable reads/writes for applications like a KV store. QuePaxa offers higher throughput in unreliable networks and hardware faults, addressing wide-area latency issues. It's not production-ready, but proofs-of-concept with up to 50 replicas show resilience; Cloudflare will publish more on architecture, verification, and deployment.

Robostral Navigate is an 8B in-house model enabling autonomous navigation with a single RGB camera in complex environments. It achieves 79.4% seen and 76.6% unseen R2R-CE, outperforming depth- or multi-sensor systems while using no depth data. Trained entirely in simulation with ~400,000 trajectories across 6,000 scenes, it uses prefix-caching for token-efficient supervised training and online RL (CISPO) to improve post-training. Navigation relies on pointing to predict the next image coordinate, with a local-displacement fallback. Generalizes across wheeled, legged, and flying robots; a step toward unified embodied AI with wide applications.

Japan's Hayabusa2 completed a close flyby of asteroid Torifune as part of its Extended Mission, delivering images and confirming mission success. The probe, which carried samples from Ryugu to Earth six years ago, approached within about 800 meters at 5 km/s. Results and photos will be shared at a news conference; the effort aims to refine precise high-speed asteroid flyby navigation and support planetary defense, with a final target asteroid expected in 2031.

The FDA has rejected a petition calling for legally binding PFAS limits in food. The Tucson Environmental Justice Task Force sought thresholds for up to 30 PFAS across produce, seafood, eggs, milk and bread in 2023; it later narrowed to advisory levels for PFOA and PFOS in seafood and milk in 2025. The agency says there’s insufficient evidence for mandatory limits and will instead propose non-binding “action levels.” Independent testing has found PFAS in seafood, milk, meat and produce, sometimes at high levels, underscoring ongoing exposure concerns.

Devon’s Exmouth Leisure Centre is heating its swimming pool with a washing-machine-sized data centre surrounded by oil to about 30C for roughly 60% of the time, saving thousands in energy costs. The “digital boiler” is provided free by Deep Green, which will refund the centre’s electricity costs; seven other England pools have signed up. The system reuses waste heat from data centres via a heat exchanger to warm pool water, addressing soaring energy bills that have shut many pools.

NoiseLang is a probabilistic language where every value is a distribution: constants are Dirac spikes and operators map distributions to distributions. Independent samples use ~, and queries trigger Monte Carlo runs to produce estimates with a standard error. It compiles to a single IR (RvGraph) with three backends—a batch interpreter, Cranelift JIT, and WASM emitter—driving bit-identical results. Performance tricks include kernel fusion, inline trig, and multi-stream RNG for high throughput. It aims for quick probabilistic insight, sitting between NumPy, Stan, and PyMC; runs in the browser at noiselang.com.

European organizations are increasingly banning or restricting personal messaging apps for work to regain control of channels and preserve a verifiable record for compliance and sovereignty. The BirdyChat post catalogs cases from 2013–2026, showing a trend from German factories in 2018 to entire governments by 2026. Examples include Belgian federal government (2026); Scottish Government (2025); UK and French governments (2023); Swiss/Norwegian authorities (2022–2023); German ministries (2020); European Commission/EEAS (2020); and major companies (Volkswagen, BMW, Allianz, Deutsche Bank, NatWest 2024). It invites updates.

Apple unveiled a multiyear deal with Broadcom to design and manufacture custom silicon and wireless components, valued at over $30 billion and delivering more than 15 billion U.S.-made chips. The agreement includes expanding Broadcom’s Fort Collins, Colorado facility with a $1.5 billion investment. As Apple’s largest AMP commitment, it supports hundreds of U.S. jobs and strengthens domestic silicon supply, aligned with Apple’s plan to invest $600 billion in the U.S. economy over four years.

GeoSQL turns Claude/Codex into a geospatial analytics agent for PostGIS, BigQuery, Snowflake, and Wherobots, running locally or self-hosted. It delivers 4x speedups on geospatial tasks via a map-in-the-loop with Dekart as the map backend. Quick start: pip install geosql; install as a Claude/Codex/Copilot plugin; run /geosql prompts in VS Code Copilot or CLI. The agent discovers schema, writes spatial SQL (ST_INTERSECTS, ST_DISTANCE, H3), validates geometry, and renders maps for feedback. Includes an eval suite with 100% pass; MIT license; contributions welcome.

Eve Online's Carbon engine is now open source on GitHub. Most modules are MIT-licensed; spatial audio clustering uses Apache 2.0, while IO is under the Python Software Foundation license. The move aims to build trust and invite community contributions, with PRs already for security fixes and interest in a web app viewer. Governance follows Godot, adopting a plug-in architecture and requiring disclosure for any LLM use. Expect heightened security review and a dedicated test project. Fenris hopes a large Eve-centric community builds infrastructure and tools around the Eve universe within five years.

Carpenter ants (Camponotus fellah) amputate injured legs of nestmates to prevent infection. No specialised medics exist; care is carried out by workers transitioning from brood care to foraging. In six colonies tracked with automated systems, carers were those with indoor–outdoor duties and prior interactions with the wounded ant. Prophylactic amputation boosts survival. The study by Dr. Erik Frank and colleagues was published in PNAS.

Tris Sherliker recounts finding an Easter-egg obfuscated Bash script printed on a Uniqlo x Akamai Peace for All shirt. The back shows a base64 string that decodes to a Bash program animating a sine-wave, color-changing 'PEACE FOR ALL' message in the terminal. OCR and transcription challenges are noted; a related shirt design is incomplete due to truncation. The piece links the design to Akamai’s history and open-source culture, mentions the Consolas font and designer Lucas de Groot, and cites Akamai’s press release about the shirt.
