Chicago O’Hare uncovered a 50-ton dolostone boulder about 30 feet beneath the airfield during ORDNext stormwater work for the airport’s massive terminal expansion. After nearly 3,000 public submissions, six finalists were named for the boulder’s official name and online voting runs through November 2, 2026. The winning name will accompany the rock in a new airport exhibit. The find under ORD’s surface highlights the engineering behind ORDNext, which aims to modernize and expand O’Hare without disrupting flights.

Stealthium introduces Rank-One Model Editing (ROME) attacks: a malicious Python module mutates a model’s weights in GPU memory during inference, without disk changes. CPU-based security tools miss these since the edit is enacted as ordinary CUDA work from Python. In a lab demo, Stealthium’s runtime sensor ties CUDA kernel launches to the Python call stack, flagging weight changes that occur alongside normal inference. The approach also links edits to the affected tensors and the code path, expanding runtime visibility beyond GPU activity alone.

Overview of fast integer-to-string conversions in C, using Lwan as example. It starts with snprintf (slow). Then a naive mod/divide method with reversal. Next, write digits backwards into a fixed-size buffer (INT_TO_STR_BUFFER_SIZE) to avoid reversing post-hoc. Further micro-optimizations include table lookups and eventually Facebook’s two-digit (00–99) lookup to cut divisions by half, yielding about 31% speedup. The number of digits can be known via digits10 or a fixed constant, with minimal gains for small numbers. Licensing blocks reuse in Lwan; origins of the two-digit table are unclear.

Online resource that disassembles and annotates the original 8 KB VT100 firmware, explaining how the Intel 8080-based terminal works and how the VT101/VT102 changes defined “VT100 compatible” per DEC manuals used for 15 years. Includes a fully annotated disassembly with links to the DEC Technical Manual and print set, plus sections on why/how the disassembly was done, bugs and oddities, an 8080 coverage checker, and related resources. Citation: Williams, Paul Flo. 2022.

Maxwell, a code execution model from doubleAI, sits inside running programs, watching data flow and reshaping algorithms and machine instructions on the fly. Each new binary version is formally proven semantically equivalent to the original, so speedups come without changing source code. Maxwell targets CPUs and GPUs, optimizing real-world workloads across pipelines and AI kernels, and can adapt as hardware and data change. Demonstrations include 4K video generation (LTX-2.5) nearly halved, faster Whisper transcription, and faster graph algorithms. Maxwell aims for self-improving code with early access soon.

Ukraine’s 92nd Separate Assault Brigade released footage it says shows the world’s first aerial drone evacuation of an injured serviceman from the front lines. Because of intense enemy drone activity and landmines, ground evacuation was impossible, so a heavy-lift hexacopter carried the wounded soldier to safety. The brigade called the mission historic; the soldier is receiving treatment. The move highlights Ukraine’s expanding drone capabilities amid a broader push to use drones for medical logistics and combat, amid shifting Western support and intelligence-sharing limits.

Beacon aims to diffuse AI into the real economy through Digital Employees and Company World Models (CWMs). Digital Employees execute defined tasks; CWMs observe business activity, propose and implement interventions, and measure outcomes, learning from operator feedback. CWMs are envisioned as co-founders—spurring new ideas, sharpening decisions, and guiding growth—while remaining aligned with owner-operators. Success relies on rich business-context data, an ontological data platform with time travel, and ongoing human judgment. In aging-ownership contexts, CWMs help preserve knowledge and enable successors, via alignment mesocosms and responsible AI.

AI-assisted writing is increasingly prevalent; provenance matters. The post analyzes Dartmouth Provost Santiago Schnell, whose Washington Post op-ed on AI cheating was flagged as likely AI-generated, with Dartmouth reporting suggesting other Schnell pieces show AI influence. Schnell calls AI an assistive tool and accepts responsibility, but the piece questions his consistency and warns undisclosed AI use harms credibility. It argues for clear provenance—documenting LLM involvement and crediting both human and machine contributors. Schnell later proposed disclosure guidelines for AI use in coursework and publications, seen as a useful starting point.

Peter Eisentraut reflects on an unusually high number of feature reverts in PostgreSQL 19 beta, noting multiple causes: mixed quality, hard-to-finish features, late beta issues, and increased defect detection from LLM-assisted code review. The Vulnpocalypse diverted security work, reducing beta review and delaying fixes. Complex interdependencies and lack of scaffolding make testing hard; he suggests experimental status for features to mature in main trees and calls for stronger interfaces. He remains optimistic that many reverts will return, highlighting upcoming features like REPACK CONCURRENTLY, logical replication of sequences, and planner hints.

yarareads is a free decodable-reading app for kids learning phonics. Each word can be sounded out; tapping reveals its sounds and a narrator pronounces the word. A word-by-word checker ensures stories use only known sounds. It supports bringing your own agent (MCP) and runs on Cloudflare Workers with static assets, D1 data, and R2 pictures. No build step is required. Users can add books, record their own sounds, and customize which sounds are taught. MIT license; stories are CC BY 4.0.

Pentulive is a Yle Areena series following Hilkka, a Lagotto Romagnolo, and her sire Zorro, documenting their puppy litter through live clips, a podcast and daily updates. Highlights include Hilkka’s recovery after birth, the puppies’ first photos, humorous moments, and viewer-name polls. The format has gone international (sold to the Netherlands; Sweden has drawn ~250,000 viewers). Episodes have included visits to a daycare and to the Ilmasotakoulu (Air Force training school), with the first year continuing in 2024.

NorForge’s investigation of exposed Cairn AI-driven pentest panels reveals how threat actors deploy autonomous agents to scan, exploit, and persist on targets. More than 20 Cairn panels expose attacker workflows, credentials, API keys, and target lists, highlighting dangerous security risk for clients and for legitimate red teams. Clusters include AIA0001 (Chinese language, 1100+ projects targeting US/JP/AU e-commerce for persistent access), AIA0002 (English, financial theft; SSH on staging hosts), and AIA0003 (English, small number of targets). The study notes automation, tools (Playwright, PHPGGC, etc.), and that dashboards are often unprotected; defenders should secure/takedown panels.
