Front-page articles summarized hourly.
Microsoft president Brad Smith warned AI is less regulated than milk and washing machines, urging urgent safety rules, including “kill switches” and a legal duty to victims of rogue AI. He said AI could be both a tool and a weapon and should be slowed with emergency brakes. Satya Nadella echoed calls for contained, observable models with an emergency brake. UK AI minister Kanishka Narayan is expected to push tighter oversight legislation. Experts warn of security risks, including theft of powerful models, with incidents like Claude misled police highlighting gaps.

Azure Maia 300 is a co-designed platform for cloud-scale AI inference, uniting software, silicon, rack, networking and cooling to maximize tokens per watt and per dollar. It uses a locality-aware NUMA memory layout, narrow-precision formats, and a scale-up rack of 96 accelerators (24 trays) forming a 12,288-accelerator superpod. A software-defined dataflow (SDLA) coordinates data movement across local memories, DMA and a two-tier network (in-rack switches and cross-rack optics). Compared with Maia 200, Maia 300 delivers up to 7x rack-scale token throughput, >2.5x performance per watt, and 2.5x memory bandwidth with integrated telemetry for optimization.

Hundreds of French supermarkets were hit by a cyberattack that heated their refrigeration units, spoiling fresh and frozen food worth millions. Hackers took control of Danfoss software used to remotely manage fridges/freezers, exploiting older devices that could not be updated. Affected chains include Coopérative U (over 100 stores), Intermarché/Netto (hundreds), Carrefour, Monoprix and E.Leclerc. Some units rose to about 50C for hours, forcing product removals and restocking. France opened a cyber-crime investigation; losses are likely in the millions.

w1700k-sdr repurposes a Gemtek W1700K Wi‑Fi 7 router as a wideband SDR receiver. It uses the MT7996 radio to sample 14‑bit IQ up to 320 Msps across 2.4/5/6 GHz, streams over 10 GbE to a Linux host, and renders live spectrum and waterfall in a browser with a 262,144‑point FFT at ~100 frames/s. The firmware is a ROM patch with no MediaTek code; host software (w1700k-stream, w1700k-spectrum) serves IQ data to clients. Getting started: install, build, connect 10 GbE, run the services. MIT license; warns about hazards and stock OS replacement.

Corey Prophitt explains how he shipped a commercial web product using a modern yet old-school stack: a single, statically linked C CGI binary backed by SQLite on OpenBSD with httpd. There’s no framework; HTML is emitted directly from C, and every asset is compiled into the executable and served from memory. The BCHS stack offers fundamentals over frameworks, minimal dependencies, simple tooling, and low supply-chain risk. Drawbacks include building cookie/query/form handling yourself; he suggests shared utilities could help (cgi.h, kcgi). He argues CGI remains viable in 2026 and that a modern web app can run with minimal parts.

Simon Koeck uncovered a DevSite flaw: a Flask session cookie on developers.google.com carried a pickle-serialized OAuth2 flow and the client_secret in plaintext. By using that secret as the Flask SECRET_KEY, he forged a valid signed cookie containing attacker-chosen data, triggering pickle.loads on the server and remote code execution. Demonstrated via time.sleep payloads. Fixes needed: rotate secrets, give each deployment its own SECRET_KEY, keep the OAuth flow server-side, store opaque session references, and drop pickle across boundaries. Timeline: Aug 6–7, 2026; $90k; fixed Oct 7, 2026.

Hayao Miyazaki, at 39 in 1980, felt his output stale after The Castle of Cagliostro and sought a new direction. He explored Richard Corben’s Rowlf, envisioning an American-market feature with a tougher female lead and surreal machinery, infusing Moebius’ influence. Despite producer Yutaka Fujioka’s push and Osamu Tezuka’s support, Corben balked at the redesigned project and Rowlf was abandoned by 1982. The experience reshaped Miyazaki: the Maryara figure evolved into Nausicaä, whose 1984 manga/film carried heavier themes that rebooted his career and deepened his storytelling with adult, liberation-focused ideas.

Tarkhanov contrasts the DHH keynote’s apparent disengagement with a Ruby renaissance. Instead of despair, the Ruby/Rails ecosystem is expanding via open tooling, new libraries, and performance gains driven by AI-assisted development. The piece argues that when leadership steps back, the community innovates. Examples include easier PDF generation with sghtmltopdf and stationery; improved Parquet support via herringbone; revived Qt bindings; Shoes resurfaced as Scarpe; ongoing gRPC improvements; and a flood of new gems. The author notes Ruby’s barriers are being lowered and asserts we should act now—build, share, and iterate rather than wait for permission.

Plug-in balcony solar panels are expanding in the U.S. as states loosen rules to allow one-to-three-panel systems that plug into a wall outlet and stay within the home. They generate electricity for household use via an inverter, typically providing 10–30% of a residence’s power and saving on bills. Costs can be under a few hundred dollars; some users report rapid payback. Utah pioneered legalization in 2025; nine other states, including California, have followed, with more considering. Safety standards (UL) and testing address grid-backfeed fears, though local zoning can block placement. Adoption could cut electricity costs by billions.

Justis Mills argues that mastering how to prompt AI (like Claude) to help others is a rare, valuable skill. He lists reasons people may avoid using AI themselves—environmental concerns, not paying for premium, being behind the times, or having latent knowledge. He emphasizes that even if AI does the work, knowing what to ask matters most. The core idea: use AI to support others and maintain human connection, rather than letting the tool replace genuine care.

Hibana is a choreography-derived runtime enforcement kernel for Rust that enforces finite-role affine asynchronous multiparty protocols. It projects a global choreography into compact role programs, with endpoints performing send/recv/route per projection. It provides a transport-agnostic runtime boundary, per-session storage, and optional resolvers, keeping protocol state local at endpoints. The project targets safety and deadlock-freedom under defined conditions, validated by Lean/Kani/Miri, with no-std footprints. It includes examples like ping_pong and is Apache-2.0 or MIT licensed.

GitHub reports an incident affecting Actions, Pull Requests, and Issues, with degraded performance and delays in operations and notifications. Initial mitigations were only partially effective; the team is investigating the root cause and applying additional mitigations. As of Oct 12, 2026, Pull Requests are operating normally, but users may still see delayed web notifications and issues loading the Actions UI, and potential delays in REST/GraphQL actions. The incident is ongoing with further status updates.

Citroën has revived its 2CV as an electric-age concept car unveiled at the Paris Motor Show. The small city car, designed as a showpiece rather than a ready-for-sale model, is planned to reach showrooms by 2028 and is expected to cost around £13,000. It borrows iconic cues—high wheel arches, tall curved roof, eye-like headlights—to ride a nostalgia wave as European brands face stiff Chinese EV competition. Analysts say heritage helps differentiation, but Citroën must offer credible modern EV tech and broad appeal.

An ongoing cyberattack has disrupted refrigeration controls across European supermarkets, triggering continuous defrost cycles at 50°C and disrupting deliveries and electronic shelf-label pricing. French chains Intermarché, Leclerc and Coopérative U use Danfoss cold‑chain tech, with Coop president Dominique Schelcher calling the incident extremely serious. In the Netherlands, Albert Heijn, Etos and Gall & Gall reported outages, compromised price labels, and suspended loyalty programs, while NOS noted site outages affecting deliveries. Belgium’s Delhaize also reported disruptions. Early estimates put losses at around €300,000 and potentially several million euros nationwide; investigations are underway.

Unpublished 2001 interview with Giles Goddard on making Super Mario 64. It details a ~15-person EAD team in a quiet Japanese office, starting from SGI Onyx emulators before hardware existed. Miyamoto led the project, testing demos and shaping Mario, the camera, and movement. The camera system was revolutionary, evolving through many iterations; early prototypes used Indy controllers. The maps formed quickly under a tight deadline; artists continued supplying assets. Highlights include the Castle world, Yoshi, water physics and sounds, and early patent-related graphics techniques that influenced the game’s feel.

Two independent studies pinpoint the orange-cat gene: a 5-kilobase deletion near Arhgap36 on the X chromosome causes orange fur by overexpressing Arhgap36 in pigment cells, shifting from eumelanin to pheomelanin. The X-linked mutation explains why most orange cats are male and why females display calico/tortoiseshell mosaics via X-inactivation. A separate white-spotting mutation also influences calico patterns by affecting melanocyte migration. There’s no established link between coat color and cognition.
