Trump floats Apple chairman Tim Cook as Jensen Huang’s successor

Following Nvidia CEO Jensen Huang's resignation on Thursday, U.S. President Donald Trump posted on Truth Social that "only one man" could replace him: Apple's Tim Cook, writing "A Legend replaces a Legend!" Cook stepped down as Apple CEO on September 1, 2026, after 15 years, and is now Executive Chairman of Apple's board; Yale School of Management's Jeffrey Sonnenfeld also suggested Cook as a candidate in a Time op-ed, citing his record of succeeding Steve Jobs.

From prototype to production: Engineering agents with Agent DLC

AWS authors propose the Agent Development Lifecycle (Agent DLC), which ties six activities—Define, Build, Evaluate, Release, Observe, and Feed Back—to an explicit "gold standard" of criteria, thresholds, and approved examples, with an inner loop (score, inspect the path, change one thing, re-evaluate) and an outer loop that updates the standard from production feedback. A reference HR policy assistant shows chunk-level retrieval precision of 1.00 on all three test questions while fact-level precision was 0.59, 0.53, and 0.09, and a prompt-only change improved one question but worsened another, which the authors attribute to missing source coverage. The post also describes a benefits-enrollment answer that scored 0.90 groundedness yet made a false claim about the user's contact preference, and outlines a one-week AWS getting-started plan using Amazon Bedrock AgentCore Evaluations and Observability.

Fine-grained access control for Amazon Bedrock Managed Knowledge Base tools

This post describes an architecture in which all employees share one agent and knowledge base, but each user can search only the documents they are allowed to view, using Amazon Bedrock Managed Knowledge Base ACL awareness exposed as MCP tools through Amazon Bedrock AgentCore Gateway. The design keeps the LLM from deciding who the user is: a request interceptor injects the verified email from the JWT into userContext, Policy in AgentCore checks it against the token's email claim, and a resource-based policy denies searches from principals other than the gateway execution role. It also covers prerequisites, ACL metadata files, tool schema configuration with parameterOverrides, and a verification script that tests each defense.

Build composable, interoperable multi-agent systems with A2A on AWS

This AWS post presents a deployed reference architecture in which a LangChain-based enterprise orchestrator in one AWS account calls a Strands Agents-based compliance SaaS agent in another account using the Agent-to-Agent (A2A) protocol, with neither side depending on the other's framework or SDK. It covers cross-framework interoperability, bidirectional agent-to-agent callbacks, and OAuth authentication in both directions using separate Amazon Cognito user pools, with deployment from three Jupyter notebooks and an end-to-end test.

Migrate to Amazon Bedrock Managed Knowledge Base with your coding agent

AWS added a knowledge base migration guide to the amazon-bedrock skill in the Agent Toolkit for AWS, which lets a coding agent plan a move from a customer-managed knowledge base to Amazon Bedrock Managed Knowledge Base, starting with read-only discovery and a plan you review line by line. On approval, the agent creates the new knowledge base and data sources alongside the original or writes a migrated infrastructure as code template, while ingestion and updating the application's Retrieve calls remain with your team. The post covers why AWS recommends the move, prerequisites, installation, planning, updating retrieval calls, and validating retrieval before cutover.

The Claude Tag guide for startups

Anthropic's guide describes how eight high-growth startups use Claude Tag (beta) in Slack, covering common use cases such as on-call triage, turning threads into pull requests, a company knowledge base, self-serve data questions, and routine reporting. It includes example channels, connectors, starter instructions, and reported results such as a PR opened 21 minutes after a Slack mention and 134 merged PRs at NavigateAI. A getting-started checklist notes Claude Tag is in public beta on Team and Enterprise plans and requires an org Owner and Slack admin to connect.

AI's Threat to Lawyers

The post argues that AI can now produce much of the output of legal expertise that was once scarce and expensive. It says the market may still need lawyers' judgment, but less often, and clients may not want to pay much for it.

Agent-access-review – an access review for AI agents' MCP configs

Agent-access-review is a Python tool that discovers AI agents and MCP servers from Claude Desktop, Cursor and VS Code configs and from agents.yaml manifests, classifies what each can read, write, execute and send, and tests that access against 14 controls mapped to NIST 800-53, SOC 2, NIST AI RMF and the OWASP Top 10 for LLM Applications. It redacts secrets before hashing evidence with SHA-256 and exports a reviewer packet, a Keep/Modify/Revoke CSV and OSCAL 1.1.2 assessment results. A bundled demo reviews five example agents, and the author reports that copying MCP configs from official READMEs yielded 8 of 9 unpinned and 7 of 9 with unreviewed write/send/execute access.

Did it use REA? Checking viral AI reverse-engineering demos

A verification page checks 39 cases described as "built with REA" against each project's README, agent files, author posts or official showcase, finding 26 confirmed, 3 partial, 4 unverified and 6 not REA (mostly Claude Code or Codex with Ghidra or IDA, or manual work). The README column was re-checked on 2026-11-10 with no changes, and X posts could not be opened from the authors' environment. It notes that two small controlled comparisons, rea-lab (482 preregistered runs) and leanrea (36 runs), found no significant gain in solve rate from REA at higher time and cost.

The AI Question

A job candidate recounts a Seoul interview where, after two rivals list their paid AI subscriptions and AI-built projects, he abandons his prepared answers and admits he does not use AI and sees no point in the question, expecting he has failed his sixth interview. On the subway home he watches more interview advice about companies wanting "quiet servants," then searches for the most popular AI tools, noting his stop is sixteen stations away.

Tests as data: Ensuring AI-generated code does what we want

The author reports that developers at Thoughtworks distrust their tests because AI coding agents refactor both code and tests as features are added, and argues AI-generated tests are often voluminous, hard to read, coupled to implementation via mocks, and may confirm current behavior including bugs. He proposes customer tests written as data in a DSL (tables, structured scenarios, textual projections of UI and state) interpreted by a small test runner that AI can generate, drawing on Fit, Specification by Example, Go's tabular tests, and Approval Testing.

The Definitive Fine-Tuning Guide for 3D Generation Models

This blog provides fine-tuning scripts and Docker containers for adapting TRELLIS.2 to custom 3D assets, runnable locally or on Hugging Face Jobs. Using LoRA adapters on only the sparse-structure and shape flow DiTs, trained on 188 GSO footwear objects, the authors report the mean F-score on nine held-out objects rising from 0.276 to 0.803, Chamfer distance falling from 0.174 to 0.033, and normal consistency rising from 0.530 to 0.804. The texture flow DiT is frozen because the dataset lacks the separate material maps that stage requires.

Jensen Huang Resigns as Nvidia CEO: What Happens Next for AI Chips?

Nvidia announced on November 12, 2026 that co-founder Jensen Huang resigned as chief executive, president and director, ending his 33-year tenure, with longtime CFO Colette Kress named interim CEO and former Synopsys chief Harvey Jones appointed board chairman while a permanent search begins. The departure followed a November 8 board announcement of an independent investigation into reports Huang was targeted by a foreign intelligence effort, which the company said gave no reason to believe its secrets or U.S. national security were compromised; Huang acknowledged marital infidelity, while related espionage allegations remain disputed and unproven. Nvidia reported $96.2 billion in fiscal Q2 2027 revenue, including $89.0 billion from Data Center, and its quarterly results call had been scheduled for November 17.

A lawyer used AI to write a report, but billed full time. What should I do?

A client says a lawyer delivered a poor-quality report with a fabricated reference typical of AI hallucination and billed a surprising number of hours, and that a first-level judge rejected the evidence presented. The client says Pangram later flagged about a third of the report as AI-generated, including the hallucinated reference, but the client does not plan to appeal due to cost and risk. The post asks what others would do in this situation.

Smarter AI Product Design Centers the User's Real Needs

In an IEEE Spectrum interview, IDEO industrial design lead Savannah Kunovsky explains how companies pressured to add AI often replace interfaces that already work, citing Humane's AI Pin and knobless cooktops as failures, and argues designers should start from user needs rather than technical feasibility. She describes how generative AI's nondeterminism shifts product definition toward evaluations and constitutions, and why fast, obvious human override is essential to consumer trust.

AI Security Issues Are Social Engineering Issues

The author argues that prompt injection is essentially social engineering applied to silicon, since LLMs, like humans, can be tricked by smuggled instructions that exploit modeled empathy or trust. He contends that capability-based security, which gives each program only the authority it needs, is a necessary but insufficient fix, and notes that projects like CHERI, Fuchsia, Capsicum, Cap'n Proto and Spritely have laid the groundwork. He hopes AI's ability to re-engineer software will help move networks onto this firmer foundation, while stressing that human flaws must also be addressed.

Advanced AI models could infer the activity of the brain

In a telephone interview, Nobel laureate Karl Deisseroth discusses optogenetics, his work on transparent brains via Clarity and StarMap, and clinical trials for autism and schizophrenia inspired by animal research. He says advanced AI models could infer brain activity and must be handled carefully, while doubting AI can capture the subjective experience of the human brain. He also describes the Human Neural Circuitry Program at Stanford and hopes to develop optogenetics treatments deliverable as simple pills.

Integrating SGLang into Spyre in Under a Week with AI

A two-person team used AI coding agents to integrate SGLang with IBM Spyre in under a week, producing a plugin of roughly 1,500 lines built on existing PyTorch Spyre support and SGLang's extension points. SGLang delivered about 3.6× the throughput of the reference PyTorch inference implementation using torch-spyre and was on par with vLLM on the measured workloads for Granite 3.3 8B and Gemma 4 26B A4B. Prefix sharing through RadixCache worked without any Spyre-specific changes.

Kazakhstan-linked hackers used AI agent to spy on Central Asian governments

CloudSEK found an exposed server belonging to the hacking group Silent Lynx containing over a dozen gigabytes of stolen government documents, hacking tools and records showing an operator used the open-source Hermes AI agent, built mainly on DeepSeek models, for reconnaissance, data collection and erasing traces. The group maintained extensive access to Tajikistan's national railway network from at least mid-August to early October and used a single employee's credentials to reach Tajikistan's national electronic document management platform, also compromising a server supporting Uzbekistan's Smart Forestry initiative. CloudSEK assessed with medium confidence that Silent Lynx is tied to Kazakhstan based on Russian-language communications and test connections from a Kazakh residential internet provider, without establishing any link to the Kazakh government.

Writing with AI – Tales and Tips

Researcher Juri Opitz describes how asking ChatGPT or other LLMs for feedback on drafts yields overwhelming lists of issues that recur even after fixes, with some suggestions useful for fluency and grammar but others stripping his natural voice or distorting meaning. He advises writing the first draft without AI, using it in carefully dosed amounts, challenging conceptual critiques by asking what would change the AI's view, and never blindly pasting suggested rewrites, noting human feedback remains most useful.

Don't build your own harness: lessons from building Paywalls AI Editor

RevenueCat describes how its Paywalls AI editor initially manipulated a custom JSON paywall schema through a bespoke harness, producing results that lacked taste despite model, prompt and skill tweaks. The team switched to letting the agent edit a JSX representation of the paywall with familiar Read, Write, Edit and compiler tools, which set a record on their blank-paywalls eval two days after the prototype and let them cut over half the system prompt and almost all skills. After rollout to 100% of users on September 2nd, positive feedback across roughly 46K requests grew 83% and negative feedback fell 40%, with gains concentrated in large edits, new paywall creation and anything requiring taste.

Show HN: AI Red Lines – write down what would make you act on AI

A Show HN project invites people to decide in advance what developments in AI would make them act, and what they would do, then share and commit to those red lines. It cites a 2016 review of 138 trials with 19,951 people finding that tracking a goal helped more when it was public or reported to someone than when private, while noting no one has tested red lines for AI. It also tells the story of Joseph Rotblat, the only scientist known to have left the Manhattan Project on grounds of conscience, after his reason for being there no longer held.
