Show HN: Low-latency local LLM runner via OpenJDK Panama FFM (Java 22)

libargus.cc is an ultra-lean, zero-allocation native AI runtime for Java 22+ (Project Panama FFM). It unifies LLM text generation, Whisper ASR, TTS, and multimodal vision/audio pipelines in one process. Built on GGML/llama.cpp, it exposes a stable C API and Java bindings to enable zero-copy, off-heap inference with GPU acceleration. Core ideas: single process backend, decoupled weights and contexts, frame-by-frame video streaming, multimodal projection, embeddings, and metadata introspection; zero-allocation memory, lock-free reads, and project-Panama integration. MIT license; designed as Layer 0 core for low-latency JVM workloads; build with CMake.

Grok Build

Grok Build is SpaceXAI's terminal-based AI coding agent with a fullscreen, mouse-enabled TUI and an extensible runtime. It understands your codebase, edits files, runs shell commands, searches the web, and manages long‑running tasks, usable interactively or headlessly for scripting/CI, and embeddable via the Agent Client Protocol. The Rust-based CLI/TUI is distributed as prebuilt binaries or built from source; first launch authenticates via browser. Documentation and user guide explain setup, keyboard shortcuts, commands, theming, MCP servers, skills, plugins, and sandboxing. The repo includes crates for pager, shell, workspace, tools, and third-party notices.

Book Prizes Don't Work How You Think

Major prizes aren’t decided by the awarding bodies but by small panels of judges who read hundreds of books. Eligibility screening is handled by the organization; outcomes hinge on individual tastes, moment, and panel dynamics, with randomness: one judge’s preferences can vault or sink a title. Submissions vary widely; fees and outreach affect what gets considered, and many strong books are overlooked. Diversity isn’t cronyism; the Pulitzer process includes a secret fourth finalist and a live final decision. Despite flaws, judging expands readers’ horizons, challenges biases, and can launch authors’ careers.

Designing APIs for Agents

The article argues that designing APIs for agents differs from human-centric design. AI agents read entire docs and generate code, so APIs must be crystal-clear, explicit, and deterministic. Defaults and forgiving error handling hinder agents; avoid coalescing and ambiguity. Use precise field names (avoid generic “name”; prefer displayName, externalId, etc.) and expose factual, verifiable states rather than extra utilities. Errors should reveal misconceptions and guide recovery. Rely on guides over bulky SDKs; keep primitives minimal and composable, letting agents adapt code to project norms. Freestyle illustrates a guide-first, agent-friendly approach.

MITS: Rockets, Calculators, and Personal Computers

Henry Ed Roberts, an Air Force electronics hobbyist turned entrepreneur, co-founded MITS to build rocket telemetry and calculators. After early products, MITS created the Altair 8800, whose Popular Electronics article in January 1975 spurred massive orders. Microsoft (Gates and Allen) wrote Altair BASIC, jumpstarting both companies; the Altair popularized the S-100 bus and led to 4K/8K BASIC, CP/M-era software, and related machines (Altair 680). MITS was sold to Pertec in 1977; Roberts left to farm and practice medicine, while the Altair influenced the modern PC era.

Brainless: Shadcn components that look like Claude Code, Codex and Grok

Workflow shows adding a "brainless" pricing block to a site. Steps: insert the pricing block into the landing page, update app/page.tsx to render <Features /> and <Pricing tiers={TIERS} />, and edit components/pricing.tsx. Run a build to verify. Then plan to place the pricing block on the marketing page (app/(marketing)/page.tsx) and rebuild. The log also notes Grok 4.21, UI tips, and session controls.

Who Is America's Homer?

This Plough feature lists essays from ten poets asking who could be America’s Homer. Each contributor weighs what an American epic poet would need—foundational status, poetic excellence, thematic depth, versatility, and historical precedence—and whether any American figure has achieved that role. While voices praise Whitman, Frost, Crane, Williams, Dickinson, Wilder, and others as possible candidates, they argue that America’s youth, diversity, and fractured mythos keep us from a single national epic. The upshot: there may be no American Homer yet; Frost comes closest, but a true national epic remains elusive.

Show HN: Capn-hook for coding agents – don't grep the same mystery twice

capn-hook provides dynamic, persistent memory for coding agents by caching the files needed to answer questions and deleting cached answers when backing files change. It cut token use by 77% on repeat questions across 5 codebases. Working with Claude Code and Codex, it uses a local .capn/ memory and a three-step loop: ask before searching, chart discoveries with capn chart (files + details), then unchart if stale. Memory is local and gitignored; charts are atomic and rebuilt if needed. Key commands: capn init, capn ask, capn chart, capn unchart, capn prune, capn list.

Duskers, the scary command line game, is getting a sequel

Misfits Attic announced Duskers 2.0 at PC Gaming Show, funded by Max McGuire’s Stray Signal project fund. A teaser trailer premiered as Tim presented the sequel, with Max signing the deal two weeks later. The post recalls Misfits Attic’s EGG funding history and prototypes (Below the Crown, Scheme) and explains Duskers 2.0’s core: a persistent, multi-dimensional loop—Explore, Adapt, Revive—balancing salvage with rescuing humanity. The piece frames the sequel within indie funding shifts and Tim’s design ethos.

Editing React components that never rendered

CrossUI Studio is a visual IDE for React built on static AST analysis rather than runtime inspection. It lets you edit components that never render by parsing sources, extracting JSX inside map callbacks, and rendering previews with mock data—without running the app. It follows imports, shows a dependency graph, and provides a canvas, prop editor, and diffs as views over the AST. Tradeoffs: dynamic imports may not resolve; config (tsconfig/jsconfig) helps. It runs in the browser with two-way sync to your repo.

Why I Left Google DeepMind

Alex Turner, a Google DeepMind researcher, explains why he left after opposing Google’s DoD and DHS contracts. He recounts trying to mobilize AI luminaries (Dean, Russell, Bengio, Hinton) and a DM employee petition to reject an 'all lawful use' deal risk‑lining lethal autonomous weapons and mass surveillance. He drafted an Oversight Framework for human control, bans on untargeted profiling, and a Defense AI Review Body. Google nonetheless signed the classified deal with weak, non-binding terms. Turner argues DeepMind’s governance failed and ethics were overridden by profit, forcing his departure.

Inkling: Our Open-Weights Model

Inkling is Thinking Machines’ open-weights, 975B total parameters (41B active) Mixture-of-Experts transformer with up to 1M token context, trained on 45 trillion multimodal tokens (text, images, audio, video). It’s released for customization on Tinker, alongside Inkling-Small (276B total, 12B active). Inkling reasons multimodally, supports agentic coding and tool use, and can generate cohesive artifacts and interactive apps. It emphasizes calibrated safety and robust epistemics, trained with RL at scale and strong safeguards. Full weights are on Hugging Face; Playground enables experimentation and fine-tuning, with API availability through partners.

Show HN: Painterly – Turn pictures into digital paintings without generative AI

Painterly is a desktop app that turns images into digital paintings using a greedy, non-AI brush-stroke algorithm. It progressively adds strokes (about 51,750) that improve resemblance to the source image, with rendering times ranging from minutes to hours depending on image size and detail. It’s in early access; users can buy or download a demo, consult documentation, and follow the roadmap and changelog. The project emphasizes no AI and invites contributions and issue reports.

Today I Rescued 7,234 Old GIFs

Dan Q recounts rescuing 7,234 GIFs from the Ibiblio Icon Browser, which used server-side imagemaps. By modeling each 72×89 icon in an 8×8 grid, he inferred the mapping from coordinates to image URLs, performed HEAD requests to uncover redirects, and used wget to download all icons. He built a Ruby-based static gallery with search and pagination and published it at ibiblio-icon-archive.danq.dev to preserve and modernize the collection.
