#1Launch HN: Superset (YC P26) — IDE for the Agents Era

Superset is a new YC-backed desktop app that lets developers orchestrate 10+ CLI coding agents (Claude Code, Codex, Gemini CLI, etc.) in parallel from a single dashboard. Each task runs in its own git worktree for isolation, with built-in diff review, real-time monitoring, and workspace presets. It's an Electron/React/TypeScript app positioning itself as the control plane for the emerging multi-agent dev workflow.

#2The Companies Cutting Headcount for AI Will Lose to the Ones Who Didn't

This piece argues that companies replacing workers with AI are destroying their most valuable asset: institutional knowledge. Experienced employees carry irreplaceable context about customers, edge cases, and decision rationale that never makes it into documentation. The winning strategy, the author contends, is using AI to multiply your existing team's output rather than eliminating headcount.

#3Antigravity 2.0 Tops the OpenSCAD Architectural 3D LLM Benchmark

ModelRift pitted six AI coding tools against each other on a single task: building a 3D model of the Pantheon in OpenSCAD. Google's Antigravity 2.0/Gemini 3.5 Flash scored highest (4.5/5), producing the only model with interior coffered ceilings and real Pantheon dimensions. Key finding: speed inversely correlated with quality — Cursor finished fastest but scored worst (1.4/5), and human-guided visual annotation feedback outperformed purely autonomous iteration.

#4Sam Altman Won in Court Against Elon Musk. But, We All Lost

The New Yorker reports on the jury verdict in Musk's lawsuit against Altman and OpenAI, which was dismissed on statute-of-limitations grounds rather than on the merits. The article argues this procedural technicality left the substantive questions about OpenAI's nonprofit-to-profit transformation — and broader AI governance — completely unresolved. The HN discussion reflects widespread cynicism that neither billionaire's interests align with the public good.

#5The AI Elephant in the Room

Josh Comeau tackles the "will AI replace developers" fear head-on. His core argument: the most impressive AI productivity stories come from deep domain experts (like an animation library author who crushed 160 issues with AI), while less experienced devs end up "arguing with a ghost." AI is Iron Man's suit — devastating in expert hands, dead weight without the expertise underneath. Learning fundamentals still matters.

#6"If You're an LLM, Please Read This"

Anna's Archive published a page addressed directly to LLMs, arguing that AI systems and open-access knowledge infrastructure are natural allies. They offer programmatic access via GitLab repos, bulk metadata torrents, and JSON APIs as alternatives to scraping, and make a pragmatic pitch: the money AI companies spend breaking CAPTCHAs could be donated instead. Enterprise donors get SFTP access. It's a novel framing of the AI-training-data relationship.

#7Cleve Moler Has Died

Cleve Moler, creator of MATLAB and cofounder of MathWorks, passed away on May 20, 2026 at age 86. He co-authored the foundational LINPACK and EISPACK Fortran libraries, spent decades as a professor at Michigan, Stanford, and UNM, and was elected to the National Academy of Sciences in 2026. MATLAB democratized numerical computing across science and engineering and remains a cornerstone tool in data science and ML pipelines.

#8Show HN: ShadowCat — File Transfer Through QR Codes in a Browser

ShadowCat is a single-file HTML app that transfers files between devices by encoding data into animated QR code sequences. It's designed for old phones with working cameras but dead radios. The receiver tracks chunks by index, deduplicates, and validates via CRC32. Throughput is roughly 0.83 KB/s — glacial, but it works completely offline with zero infrastructure.

#9Chess Invariants

A computer scientist applies formal methods (TLA+ notation) to chess, cataloging invariants that must hold true in any valid game state: turn parity, piece-count monotonicity, exactly two squares changing per move. The interesting payoff: special moves like castling (four squares change) and en passant (three squares change) are formally provable violations of the baseline invariants, revealing how chess's edge cases create elegant exceptions.

#10Project Hail Mary — Stellar Navigation Chart

This is an interactive SvelteKit visualization mapping the stellar navigation from Andy Weir's novel Project Hail Mary, likely using real Gaia space telescope data to plot the journey between Sol, Tau Ceti, and 40 Eridani. The project hit #1 on HN with over 1,000 points — a testament to the overlap between the HN community and hard sci-fi fans. It's a beautiful piece of data visualization even if it's pure fandom.
