The article argues that evaluating next-generation LLMs is the bottleneck for progress. Benchmarks assume smoother gains and miss qualitative shifts; metrics can mislead (emergent abilities, grokking). We lack order parameters to signal phase transitions, so we’re blind at deployment scale. To fix, invest in predictive, adaptive evals that co-evolve with models: identify order parameters, monitor meta-signals, and build self-evolving tests that generate new cases as capabilities change. Evaluation must precede training to scale safely.

Google is unifying Gemini CLI into Antigravity, a single agent-first platform with a new Antigravity CLI and server-side harness. Core Gemini features—Agent Skills, Hooks, Subagents, and Extensions—continue as Antigravity plugins, with faster Go-based execution, asynchronous multi-agent orchestration, and a shared backend with Antigravity 2.0. Antigravity CLI is available now; on June 18, 2026 Gemini CLI and Gemini Code Assist IDE extensions stop serving requests for Google AI Pro and free tiers. Enterprise access remains; try Antigravity CLI with Google Cloud projects and share feedback.

An exploration of unusual OEIS references in open-source code, especially live-coding music. Two projects—Mercury and ziffers (a Sonic Pi extension)—use OEIS sequences to drive musical decisions. Mercury cites Fibonacci-related sequences (A000045, A006190, A000032, A000129); ziffers includes De Bruijn (A000695), Recamán (A005132), Thue–Morse (A010060), Dress (A001316), and more, plus 10-adic expansions like A225410 and the Inventory Sequence (A342585). The piece questions how such sequences sound as music, notes a Kobo Plato pen-size option using A000041, and mentions a geocaching app with many OEIS formulas. Seeks reader feedback.

Plantin-Moretus houses the world’s two oldest printing presses, dating from around 1600. In Christoffel Plantin’s era the workshop ran about 16 presses and 56 workers, the largest of its kind. Today seven presses remain in the room, five still operational, with the two oldest worn presses at rest. They produced about 1,250 sheets per day on a 14-hour workday. The intact 16th‑century workshop also showcases the museum’s broader heritage, including Rubens portraits and fine furniture.

An in-depth primer on the UNIX/Linux TTY subsystem and why it matters. Traces the history from teletypes to video terminals and explains how a TTY device (the UART driver + line discipline + TTY driver) mediates between a user process and a terminal. It covers session and job control: foreground process groups, signals (SIGHUP, SIGINT, SIGTSTP, SIGCHLD, SIGTTIN, SIGTTOU, SIGWINCH), and how the kernel, via /dev, coordinates editing, echo, and flow control. It explains canonical vs raw modes, pipes, ptys, and how to use tools like stty and ps. Concludes with practical grounding.

Co-Packaged Optics (CPO) integrates the optical engine—InP laser, silicon photonics (SiPh) chiplet, modulators, detectors—directly with the switch ASIC, removing front-panel transceivers’ long electrical traces and lowering power per bit while increasing per-port bandwidth (1.6–6.4T). The four-layer package: InP laser die; hybrid bond to the SiPh chiplet; the SiPh chiplet; and the switch ASIC. Chokepoints: SOITEC, ASML, Sumitomo/IQE, EV Group, TSMC CoWoS, and laser makers (Lumentum/Coherent/Sivers). Broadcom shipped CPO at scale in 2025; NVIDIA/hyperscalers follow in 2026–27. Curated by Leonardo Boquillón.

remove-ai-watermarks is a CLI and Python library to remove both visible (Gemini/Nano Banana) and invisible (SynthID, C2PA, EXIF, XMP) AI watermarks and associated metadata from images. It uses reverse alpha blending for visible watermarks and a diffusion-based pipeline for invisible ones, with optional face protection and an Analog Humanizer to preserve realism. Supports Gemini, DALL-E/ChatGPT, Stable Diffusion, Adobe Firefly, Midjourney and more; offers batch processing and a web service (raiw.cc). Install via pipx or uv; GPU recommended for invisible watermarks. MIT license.

Prosser argues AI leaders suffer from 'Dr. Manhattan Syndrome': they speak in abstraction about 'Humanity' and civilization, while ignoring real people. He points to Greg Brockman’s $25 million gift to MAGA Inc, framed as a mission bigger than companies, to show the disconnect between rhetoric and affected lives (jobs, privacy, homework). The piece links this to nuclear-practice PR, where deficit-model distrust followed public concerns. With AI skepticism rising (Pew data), the fix is to talk to people, name trade-offs, and center individual users—like Jobs’ 'a thousand songs in your pocket'—not grand civilizational myths.

Paul Graham argues Lisp is advantageous for Web-based applications because you control the servers and can write in any language; this freedom requires wise language choice. Lisp supports incremental development, as shown by Viaweb’s growth from 120 lines to 25k without rewrites; its interactive toplevel aids rapid debugging and hot fixes. Macros for HTML and an embedded language called Rtml let templates be high-level, programmable, and easily changeable, providing an upgrade path. Closures simulate subroutine-like control over stateless web flows (continuation-passing style), enabling dynamic, user-driven CGI-like interactions.

Growing Neural Cellular Automata (G-NCA) develop 2D patterns from a single seed using a differentiable, per-cell update rule learned from data. The model perceives neighbors via fixed Sobel gradients and updates cell states with 8,000 parameters; updates can be asynchronous via per-cell dropout. Four experiments explore growth, persistence (attractor dynamics), regeneration after damage, and rotating perception fields. Training with a pool of states and occasional damage yields robust, regenerating patterns and long-term stabilization. The work connects neural networks, cellular automata, morphogenesis, and decentralized self-organization, with implications for regenerative robotics and bio-inspired computation.

Minnesota signed the nation's first law banning prediction-market sites like Kalshi and Polymarket, making it a felony to host or advertise such markets and to use tools that help evade the ban. The law, which takes effect in August, includes a weather-hedging carve-out and other exemptions (for certain contracts). It could force operators to leave the state, while the CFTC and the Trump administration challenge it in court, arguing federal oversight. Supporters say regulation is needed for safety; opponents say it harms competition and innovation. Additional states are considering similar measures.

The Silver Swan is a life-size automaton at The Bowes Museum (Barnard Castle, UK). Originating from James Cox’s London workshop (1773), it was showcased at the 1867 Paris International Exhibition and valued at 50,000 francs before John Bowes bought it in 1873 for 5,000 francs (£200). The swan has 2,000 moving parts and 139 crystal rods, with three clockwork systems—the pool, music, and the head/neck mechanism by John Joseph Merlin. After restoration, it now performs daily at 2pm (plus 11:45am during holidays).
