FurtherAI built self-correcting AI agents to extract loss runs for commercial insurance. Loss runs vary in format across carriers, with about 30 fields per claim; initial extractions produced duplicates or missing claims (38 extracted vs. 35 stated). They shifted from prompt-based extraction to a non-prescriptive task with a validation tool, enabling the agent to iteratively extract, inspect pages, and validate totals against the document summaries. The agent checks its output and fixes mismatches until counts and dollars align. Four keys: agentic loops, validation tools, flexible success criteria, and rigorous evals. Result: high accuracy and speed.

Iranian strikes have left two AWS availability zones in Dubai and Bahrain “hard down,” with outages expected to last an extended period. An internal AWS memo directs deprioritizing these regions and running workloads with a minimal footprint while migrating customers to other regions. AWS says it’s helping affected customers migrate and that many already operate from elsewhere. Bahrain and Dubai facilities have suffered multiple hits, and IRGC threats loom over other tech giants; no timeline for return to normal operations.

Paula Maddox's DCJ11HackPlus project shares DCJ11-based boards (main CPU, RAM/ROM/text display) with KiCAD schematics, PAL files, and a backplane. It includes a 16x16 dot-matrix display, a 16-bit word-only memory map, and test/code examples. Code samples (Hello World, Knight Rider, terminal tester) are in .asm and .oct; designed for PDP-11 assembly and tested with a PDP-11 simulator; default baud is 115200. A hobbyist project leveraging backplane expansion, it has moved from GitHub to Codeberg.

PIGuard introduces a lightweight prompt-guard against injection attacks and NotInject, a dataset to measure over-defense. NotInject contains 339 benign sentences with trigger words common in prompt injections, showing current guardrails exhibit over-defense and drop to ~60% accuracy. PIGuard employs Mitigating Over-defense for Free (MOF) training to reduce trigger-word bias, achieving state-of-the-art results on NotInject and other benchmarks, and surpassing PromptGuard, ProtectAIv2, and LakeraAI by ~30.8%. NotInject was built by identifying trigger words via frequency differences, filtering with LLMs and humans, and generating diverse sentences with 1–3 trigger words. PIGuard is 184MB and open-source.

RepoProver is a multi-agent framework to automatically formalize mathematics textbooks in Lean. It coordinates sketcher, prover, maintainer, and reviewer agents that collaborate in a shared Lean project, using a lightweight, filesystem-based issue tracker and a merge queue to keep the main branch building. It supports Lean projects with Mathlib, LaTeX sources organized by chapters, and manifests mapping chapters to target theorems. It includes a toy example, SLURM-enabled multi-node runs, and trajectory tooling for monitoring agent progress.

Oracle filed over 3,100 H-1B petitions in FY2025–FY2026 (2,690 in 2025 and 436 so far in 2026) while laying off thousands of U.S. workers in a major restructuring. The filings spur questions about using H-1B visas to replace American workers and the program’s impact, with Oracle offering no public comment.

Seven changes turn a multi-homed Linux host into a WiFi router: enable IP forwarding; create br0 bridging eth0 and wlan0; set nftables rules for forwarding; use conntrack for stateful firewalling; NAT with masquerade on outbound; dnsmasq for DHCP/DNS on br0; and hostapd to run WLAN as an AP on the bridge. The article ties these steps to kernel hooks, bridge operation, and practical inspection commands (ip_forward, brctl, nft list ruleset, conntrack -L, iw).

NASA's Artemis II crew released high-res Earth images from the Orion capsule as they head toward Moon. Commander Reid Wiseman captured 'Hello, World,' showing the Atlantic, a thin atmospheric glow and polar auroras, with Earth upside down and Venus bright at the bottom-right. A second image, 'Artemis II Looking Back at Earth,' shows the day–night terminator across the planet. The photos follow a trans-lunar injection burn that sent the four-astronaut crew on a looping path around the Moon—the first such journey since 1972—with return to Earth on April 10. No Moon landing this flight; a 2028 landing is hoped.

Via Licensing Alliance restructured H.264/AVC streaming licenses, scrapping the $100k cap in favor of tiered fees up to $4.5M/year for the biggest platforms. New terms apply to unlicensed licenses issued in 2026+; existing licenses stay under old terms. Tiering targets OTT, FAST, social media, and cloud gaming, with Tier 1 at $4.5M, Tier 2 $3.375M, Tier 3 $2.25M; small/nascent platforms keep $100k. The move follows steep HEVC/H.265 fee hikes and augments broader royalty pushes on HEVC, VVC, VP9, AV1 that could push platforms toward nine-figure costs.

Waymo’s Austin self-driving cars repeatedly passed school buses with flashing lights and stop arms, despite a December recall and AISD’s bus-signal data collection. At least 19 alleged violations prompted NHTSA and NTSB investigations. Even after software updates, incidents persisted into January; one case involved a remote assistant misreading a bus, and a later Santa Monica incident underscored risk. Experts say teaching AI to handle subtle, context-dependent cues like school buses is extremely hard, and Waymo should limit school-area testing until fixes are proven.

DIY guide to a vertical sliding, self-locking, predator-proof chicken coop door. The door uses shelf-track guides on a 2×4 frame and a pull string from outside; a counterweight and latch let it self-lock as it lowers, preventing predator access. Includes materials and nine steps—from outlining the opening to installing the latch, counterweight, and pull handle—with notes on variations (spring hinge or no counterweight).

DBOS explains that durable Python workflows must be deterministic for replay-based recovery, but async patterns like asyncio.gather complicate order due to concurrent tasks. The Python event loop is single-threaded; tasks are scheduled in FIFO order, but their execution order is non-deterministic. The solution is to assign deterministic step IDs before awaiting, e.g., via a @Step decorator, ensuring step one, two, etc., while still enabling concurrency. Understanding asyncio internals is crucial to build simple, concurrent yet safe durable workflows.

An overview of the 1930s technocracy movement led by Howard Scott, which envisioned a centralized state—the Technate—run by engineers via energy accounting and social engineering. It peaked in 1933 but faded after critique and credential gaps. The piece argues that many core ideas persist in today’s tech elites, who pursue data-driven social prediction and control, treating technology as a revolutionary agent. It links calls to “exit democracy” and surveillant capitalism with Ellul’s concept of the “technique”—an unstoppable pursuit of efficiency that erodes autonomy.

Young audiences (18–24) are now 'social-first' news consumers, primarily getting news on TikTok, YouTube and Instagram, with direct access to publisher sites fading (14% main access; around 64% read daily vs 87% of 55+). They prefer audiovisual formats, value entertainment and personal relevance, and are more open to using AI and following individual creators. Trust and impartiality are similar to older groups but slightly lower for youth. For publishers, pathways, formats and definitions of news must adapt—emphasizing short-form video, audio, AI summaries, and collaboration with creators.

TinyGo is a Go compiler based on LLVM that brings the Go language to embedded systems and the modern web. It targets over 100 microcontroller boards—from BBC micro:bit and Arduino Uno to Nordic Semiconductor and ST Microelectronics—and can also produce WebAssembly (WASM) code for web browsers and WASI-enabled servers and edge environments. The site provides getting-started guides and examples (Hello world, blinking LED, RGB LEDs, Display) plus a TinyGo Playground, GitHub, and community links.

RAG limitations spurred a filesystem-like doc interface. Real sandboxes were too slow and costly, so Mintlify built ChromaFs, a virtual filesystem that maps UNIX calls to Chroma DB queries via just-bash. It boots from a gzipped path tree, builds in-memory file sets, and enforces per-user RBAC by pruning before building. Pages split into chunks and reassembled on access; large specs are lazy-loaded from S3. Grep is accelerated with a coarse Chroma filter plus in-memory regex. Result: instant session creation (~100 ms), near-zero marginal cost, and scalable access for hundreds of thousands of users across 30k+ conversations.
