Show HN: TUI-use: Let AI agents control interactive terminal programs

tui-use is an open-source tool that lets AI agents control terminal programs by spawning them in a PTY and rendering the program screen as plain text. It addresses the gap where CLI tools expect human input by enabling automated interaction through commands like start, type, press, snapshot, and wait. Use cases: interactive REPLs, CLI wizards, database CLIs, SSH sessions, and TUI apps. Features include full VT rendering via headless xterm, a snapshot model with highlights for active items, and rich key support. Installation via npm -g tui-use or from source; MIT licensed.

Show HN: BAREmail ʕ·ᴥ·ʔ – minimalist Gmail client for bad WiFi

BAREMAIL is a minimalist, offline‑first Progressive Web App Gmail client that talks directly to the Gmail API from the browser with no backend. The app shell is under 200KB gzipped and cached by a service worker; emails are cached in IndexedDB for offline use. It offers inbox, reader, compose, search, labels, keyboard shortcuts, and background outbox sync. Tech stack: Preact + HTM, TypeScript, esbuild. Setup uses a Google Cloud OAuth wizard; it can be installed as a PWA and deployed to major hosts.

Muse Spark: Scaling Towards Personal Superintelligence

Meta unveils Muse Spark, the first Muse model from Meta Superintelligence Labs: a native multimodal reasoning model with tool-use, visual chain-of-thought, and multi-agent orchestration. It scales toward personal superintelligence, with investments across pretraining, RL, and test-time reasoning, plus Hyperion infrastructure. Available now at meta.ai and the Meta AI app, with an API preview. Contemplating mode enables parallel-agent reasoning, delivering gains of 58% on Humanity’s Last Exam and 38% on FrontierScience. Health applications leverage physician-curated data. Efficiency gains mean similar capabilities use over 10x less compute than Llama 4 Maverick. Safety reviews show refusals in high-risk domains; rollout is gradual.

I Ported Mac OS X to the Nintendo Wii

Ported Mac OS X 10.0 Cheetah to the Nintendo Wii by building a custom bootloader, patching the XNU kernel, and writing drivers for the Wii’s Hollywood/Starlet. Key steps: hardware mapping (PowerPC 750, MEM1/MEM2), a minimal device tree, Mach-O kernel loading, kernel patching (BATs) and a dual-framebuffer to fix colors, a USB OHCI driver via patched IOUSBFamily, and an SD-card driver (MINI) to mount the root filesystem. Bootloader now supports multi-partition boot and loading drivers from a memory-map; drivers are progressively separated from the kernel to simplify maintenance. A long experimental process with milestones.

Virtual Mars Traverse: Every inch of Curiosity rover's path since 2012 landing

Teardown of unreleased LG Rollable shows why rollable phones aren't a thing

Ars Technica reports on a YouTube teardown of LG's unreleased Rollable phone, revealing why rollables never took off. The prototype uses two geared motors and a lattice of arms to unfurl a screen about 40% larger, but its internal complexity, expensive production, potential durability issues, and high price would have made it impractical. LG abandoned smartphones after Wing; other firms likewise demoed rollables but none released. The teardown shows the form factor remained technically impressive but commercially untenable.

Microsoft Abruptly Terminates VeraCrypt Account, Halting Windows Updates

Microsoft terminated the signing account used by VeraCrypt’s developer IDRIX, halting Windows updates and the signing of Windows drivers and the bootloader. Idrassi says he received no prior warning; Microsoft reportedly told him the organization no longer meets verification requirements and that there are no appeals. Linux and macOS updates can still be published, but Windows updates are blocked, a major blow for VeraCrypt’s Windows user base. The issue reportedly affected WireGuard as well; Microsoft did not comment by publication.

The Future of Everything Is Lies, I Guess

Aphyr argues that current AI, especially LLMs, are powerful yet fundamentally flawed “bullshit machines”: they predict text from patterns, lack true memory or understanding, and frequently lie or mislead. They’re not conscious, but humans treat them as intelligence. The piece catalogs confabulation, brittle cognition, and the “jagged technology frontier” where capabilities are uneven; bigger models may not keep delivering. It warns of risks across work, politics, art, and safety, and calls for careful, nuanced scrutiny over boosterism.

Show HN: Go-Bt: Minimalist Behavior Trees for Go

go-bt is a minimalist Behavior Tree library for Go designed for background workers, game AI, and automation. It uses cooperative multitasking: each node Run returns 1 (Success), 0 (Running), or -1 (Failure). Nodes are stateless; runtime state lives in BTContext[T], which embeds context.Context for cancellation and timeouts. Features include composites (Selector, Sequence, MemSequence), decorators (Inverter, Optional, Timeout, Retry, Repeat), leaves (Condition, Action, Sleep). Supports time-travel testing via an injected clock. Quickstart: define a Blackboard, build the tree, and run a background Supervisor that ticks periodically.

Show HN: Explore the Silk Roads through an interactive map

An interactive Silk Roads map by Into Far Lands lets users explore routes, traded goods, resources, and Silk Road outposts. Legend explains finished pages (orange), charted pages in development (black), and unvisited significant outposts (dots). The site chronicles eight years and 30,000 miles of travel and a hand-drawn silk map uniting East and West; visitors can order the map. Sections include Our Silk Road Quest, stories, outposts, kingdoms, Angkor, and more; contact [email protected]. Includes disclaimer/privacy policy.

Show HN: I pipe free sports streams into Jellyfin – no ads, just HLS

Lightweight HLS restream proxy for Jellyfin/Emby/Plex. Injects necessary HTTP headers, rewrites M3U8 playlists, and auto-refreshes tokens so segment requests pass through the proxy. Core tools: hls-proxy.py (HTTP reverse proxy adding headers), refresh-m3u.sh (scrapes pages to extract m3u8 URLs and write stable channel URLs), detect-headers.sh (auto-detects required headers), and channels.conf (channel list). How it works: Jellyfin -> proxy -> upstream HLS -> segments; proxy learns the required Referer, caches URLs (1 hour), and keeps M3U URLs stable. Requires Python 3.8+, bash, curl, grep -P. MIT license.

The Harvard Library Passport

An affectionate, humorous overview of Harvard’s library system framed as a “Library Passport” with stamps at each location. The piece lists numerous libraries—from Widener and Lamont to Houghton, Loeb, and the Yenching Library—rating them on aesthetics, study space, convenience, and quirky traits. It combines playful anecdotes (Remy the Cat, lobster illustrations, underground Kennedy School) with candid judgments, concluding Widener as the best and Ernst Mayr Library as the most underrated, celebrating the sprawling, idiosyncratic campus library culture.

They're Made Out of Meat (1991)

Two alien researchers debate humans after studying Earth. They reveal that humans are sentient but made entirely of meat—brains, thoughts, even songs are meat. Although humans send radio signals, the aliens decide not to contact meat, officially logging all sentient races while unofficially erasing Earth and pretending it’s unoccupied. They hint at other intelligences and the universe’s loneliness. The tale satirizes assumptions about life and intelligence by showing that thinking beings can be meat, too.
