A discussion around Herb Sutter’s piece on the rift between C++’s creator and its stewards highlights growing doubts about C++’s future, with commenters citing memory safety, AI-assisted rewrites, and weak safe-concurrency support as reasons legacy C++ may be increasingly hard to defend. Others credit Sutter and the C++ committee for foundational work on concurrency and memory models, while debating whether those efforts made parallel programming meaningfully easier.

A security flaw allows any car from a specific brand to be unlocked across most of the world, according to a new disclosure. The author, a longtime owner of the brand who bought a new SUV in 2023, highlights the widespread automotive security risk.

Researchers have turned silicon wafers into flat ultraviolet focusing mirrors by patterning them with air holes, using metasurface-style phase control. The approach could enable compact UV imaging, spectroscopy, and sensing systems while addressing the strong UV absorption that limits many metasurface materials.

In Cormac McCarthy’s essay “The Kekulé Problem,” he asks where language came from and argues that it likely arose from the unconscious mind rather than conscious invention, using Kekulé’s dream of the benzene ring as an analogy. McCarthy suggests language is a problem solved beneath conscious awareness, leaving its ultimate origins mysterious.

Nvidia’s board is launching an independent investigation after recent reports that founder and CEO Jensen Huang was the target of a foreign intelligence effort. A board committee is overseeing the probe.

Goldman Sachs is withdrawing Claude Code from its bankers and traders and handing AI coding agents back to its engineers under new internal guidance. The reversal comes after its tech chief praised trader-built AI tools in July and just weeks before Goldman takes Anthropic public.

Nvidia CEO Jensen Huang’s letter to staff about an affair has sparked discussion after one report described the woman as a suspected Chinese spy, while Nvidia’s official message focuses on national security concerns and does not confirm the spy allegation. Readers noted that the relationship and the espionage question are separate issues and debated the security risks facing powerful executives, including honey traps and the need for safeguards.

OpenAI has raised $11 billion at a $1.25 trillion valuation, though not on the terms it wanted. The gap between its growth story and investor appetite is now hitting two giants, with one facing a bookkeeping hit and the other becoming more dependent on the funding flow.

U.S.-based Ornadyne’s bird-mimicking drones evaded detection during an Air Force technology exercise. The drones are designed to resemble birds found in any region of the world.

GitHub users reported another frustrating outage, with some unable to download Linux distros and tools while the official status page showed everything as operational. Commenters criticized GitHub’s reliability and status-page transparency, noting that incidents often go unlisted and that outages tend to hit during peak demand. Some suggested third-party uptime trackers, though even those were questioned as the incident unfolded.

A UIST 2026 Best Paper introduces declarative dragging, a technique that lets interface authors make an element draggable by specifying which future model states should be reachable through dragging. The approach shifts drag behavior from imperative event handling toward declaring accessible states.

GitHub has launched a public preview of a new pull request overview page designed to make long PRs easier to navigate. The page surfaces merge status and blocking issues without forcing users to scroll through comments and timeline events to reach the merge box.

A new project, llama-modchip, demonstrates running a 284B DeepSeek-V4-Flash model and 30B mixture-of-experts models entirely on a 64GB CPU with no GPU. It reports under 59GiB RAM use, 256K context, and throughput of 9.1–14.7 tok/s for the 284B model and 25–111 tok/s for the 30B MoEs.

In the November 2026 Ask HN thread, developers shared a wide range of side projects and tools, including a YouTube pitch-shifting extension, a Google Local Service Ads-integrated CRM for field-service businesses, a singing-training app, and a macOS document library that indexes files in place. Other highlights included open-source public transit software used by major cities, LLM-powered sunset alerts for San Francisco, real-time meeting speech feedback, an AI loan-servicing platform, and a fresh attempt at the Netflix Prize using LLMs.

SpaceX is planning Starship Flight 15 for November 13, with the ambitious goal of catching both the Super Heavy booster and the Starship upper stage. The attempt would mark a major step toward fully reusable rocket operations.

A Linux script called RAM Altman is meant to email Sam Altman every day with a report on how much unused RAM the user’s PC has. Readers also discussed invasive anti-ad-blocker modals and compute centralization, with one noting the script isn’t configured to actually email Altman by default.

Since November 5, Outlook.com and Hotmail have been bouncing email from domains that lack a DMARC record, affecting even small senders. Senders now need to publish a DMARC record to avoid delivery failures. The suggested fix is a single DMARC DNS record.

Agent memory tools each use their own formats and cannot read one another, creating the same fragmentation observability once faced. The piece argues agent memory needs an OpenTelemetry-style shared data model, surveying existing formats and proposals. It also outlines what such a common spec could look like.

Drugmaker CEOs are skeptical of Silicon Valley’s promise that AI will cure disease, with reader discussion questioning how many concrete life-saving breakthroughs AI has delivered so far—AlphaFold is often cited, but commenters say the evidence remains limited. Readers argue AI can still help by improving diagnosis, analyzing research and patient data, and matching treatments without needing to cure disease outright. They also warn that AI could accelerate pharma work but may amplify centralized reasoning, political bias, and research monoculture.

Ad data collected by popular apps is giving police a powerful surveillance tool, with commenters arguing Google is failing to enforce its own Play Store policies against selling sensitive user data through third-party SDKs. They advise users to restrict location permissions, be wary of apps like weather services that request background location, and prefer browsers with ad blockers, though app-first services make that difficult for ordinary users.

PacketHound is a free outbound firewall for Windows that watches apps’ internet access. The first time an app tries to connect, it asks users whether to allow or block it.

A new approach brings just-in-time bitmap text rendering to microcontrollers, generating glyph bitmaps on demand to reduce memory use and support flexible fonts on constrained hardware. It targets embedded displays where storage and compute resources are limited.

Mizu introduces zero-copy parallel and asynchronous execution between R and Python over shared memory, aiming for thread-speed performance. The shikokuchuo/pymizu project provides tooling for running Python workloads alongside R without copying data across process boundaries.

Dux is a free, open-source Wayland desktop shell offering a modern Linux desktop suite with file management, theming, widgets, and powerful monitoring. It is optimized for compositors including niri, Hyprland, mangowm, Sway, and Miracle WM.

The “Goodbye Claude, Hello Pi” post centers on a developer moving from Claude Code to Pi, a coding-agent harness that supports OpenAI Codex out of the box with basic integration and optional extensions for usage tracking. Discussion around it covers frustrations with Claude Code, such as errors tied to simple shell aliases, and comparisons between Pi, opencode, and local-model workflows. The author is identified as a Salesforce developer, suggesting the piece is a personal migration account rather than a formal product announcement.

Paul Ford argues that modern web browsers are capable enough to support incredibly rich app development, making dedicated native apps less necessary. He notes that building these experiences on the web is now radically easier than it used to be.

A new approach to reconstructing torn documents uses computational analysis of fragments to automate matching and reassembly. The technique could speed restoration of damaged archives and help recover information from shredded or torn records.

A new open field guide catalogs 39 types of CAPTCHA, detailing identification signals and methods for breaking them. It covers free and open-source bypass techniques along with paid alternatives, and includes a searchable web version.
