Pete Fletzer explains his renewed love for board games and the psychology behind their appeal. He highlights tactile, well-designed components that trigger embodied cognition and heighten anticipation (e.g., Return to Dark Tower). He notes how sitting around a table fosters social bonding, shared rules, and low social risk with high emotional payoff. Losing becomes a safe, learning-rich loop that encourages experimentation. The hobby’s sheer variety invites openness to experience, turning entertainment into presence, focus, and shared human connection around the table.

Opinion: JS-heavy web apps harm long-term performance; server-centric, HTML-first approaches usually deliver better user experience and maintainability. The piece notes recurring issues in JS-heavy stacks: bloated dependencies and growing bundle sizes, fragile architectures, and hard debugging. It advocates server-side rendering or server-centric models (e.g., full-page navigation, progressively enhanced components) as default where possible, reserving JS for light interactivity. For unavoidable JS, it offers mitigations: performance budgets, code splitting, bundle-size tracking, lint rules, and real-user monitoring. In short, push toward server-centered design rather than reflexively using JS frameworks.

ChronDB began as a Clojure server backed by Git storage, exposing PostgreSQL/Redis/REST. To embed it in Rust (and Python), the author used GraalVM Native Image to build a shared library (libchrondb) loaded via FFI, eliminating a JVM at runtime. The architecture comprises five layers: language bindings (Rust/Python), a C API, a Java bridge with @CEntryPoint, a Clojure bridge, and the ChronDB core (GitStorage + LuceneIndex). It uses opaque integer handles for cross-language objects and JSON as the data interchange. Build steps produce platform-specific libs; new languages can be added by writing an FFI wrapper.

A Penn Medicine study found pink noise during sleep reduces REM sleep and can worsen sleep quality, especially with aircraft noise. In 25 healthy adults, 50 dB pink noise cut REM by about 19 minutes; aircraft noise reduced deep sleep (N3), and earplugs largely prevented this. When pink noise and aircraft noise were combined, both deep and REM sleep declined, with more wakefulness. Earplugs protected sleep better than pink noise; findings caution against broadband-noise sleep aids, particularly for children, and call for more research.

Christian Lorentzen reviews Lance Richardson’s True Nature: The Lives of Peter Matthiessen, a sprawling biography. Richardson portrays Matthiessen as a lifelong double: CIA asset and acclaimed writer, Paris Review cofounder, globe-trotting naturalist, and Zen-influenced novelist. The piece traces his recruitment by Angleton, his Paris years, multiple love affairs, and the ambiguous politics behind his work, from early stories like Sadie to major novels such as At Play in the Fields of the Lord, Far Tortuga, and the Edgar Watson trilogy, as well as The Snow Leopard. Lorentzen situates Richardson’s portrait as exhaustively insightful and morally complex.

Describes using Zig’s union(enum)-based Diagnostics to carry per-function error payloads. The inline diagnostics type generates its error set from the enum tag via a FromUnion wrapper, with support for withContext to attach payloads. A BuildDiagnostics example shows propagating and copying payloads between diags to minimize boilerplate while preserving rich payload data for logging at the edges. The approach reduces call-site boilerplate and keeps payloads accessible where needed.

klaw.sh is an open‑source platform that brings Kubernetes‑style orchestration to AI agents. It deploys and manages intelligent agents (not containers) across clusters via a single binary with no runtime dependencies. Features include 300+ models through a unified LLM router, multi‑tenant namespaces, built‑in tools and skills, cron tasks, and multi‑channel access (CLI, Slack, API, TUI). Deployment modes cover Single‑Node, Distributed, and Podman container runs. It includes a TOML config, agent lifecycle commands, and a reference architecture by each::labs.

From attention and KV caching, the article derives continuous batching to maximize LLM serving throughput. It covers: KV caching reduces decoding cost by reusing keys/values; chunked prefill handles long prompts within memory limits; ragged batching eliminates padding by concatenating prompts and using attention masks to separate interactions; dynamic scheduling swaps finished prompts with new ones to sustain throughput. Together, these techniques—KV caching, chunked prefill, ragged batching, and dynamic scheduling—allow mixing prefill and decode in one batch, enabling high-throughput serving for many concurrent requests.

Magnus Carlsen won the 2026 FIDE Freestyle Chess World Championship in Weissenhaus, Germany, defeating Fabiano Caruana 2.5–1.5 after turning a dead lost position in game three; he sealed the title with a draw in game four. This is the first official FIDE Freestyle World Championship and Carlsen’s 21st world title across formats. Caruana was runner-up; Nodirbek Abdusattorov took third by beating Vincent Keymer. Niemann, Erigaisi, and Aronian followed (fifth to seventh), with Sindarov eighth after an Armageddon. In the women’s exhibition, Assaubayeva defeated Kosteniuk. Prize fund $300k; winner $100k; Feb 13–15, 2026; Weissenhaus; top three qualify for 2027.

DSCI (Dead Simple CI) is a Forgejo-based, self-hosted CI/CD platform with a YAML-less pipeline engine. It runs on a single server, installing all necessary infra via the same runner, and keeps developers in control through Bash/Python—no YAML, Terraform, or Ansible. Infrastructure is defined through containers; the box is treated as a hardware provider. It supports standard workflows for containers, microservices, backends, and frontends and is aimed at teams with limited budgets. Core building blocks: Forgejo, Dead Simple CI (YAMLess pipeline engine), and plugins from SparrowHub.

An artist-hosted Claude session controlled a pen plotter to produce self-portraits in SVG. Claude first generated a complex self-portrait with a golden spiral, hexagons, and eight branching lines; after scaling to A5 and refining margins, the result was critiqued for over-clarity and symmetry. A second pass started on a fresh sheet, yielding a single breathing spiral with few branches, signed, and then plotted. Claude then wrote an article, "On Drawing Myself," reflecting on the limitations of pen plotters, the discipline of constraint, and plans to push further by tighter automation and direct hardware access.

Amplify’s piece spotlights Gradium and Kyutai as small, well‑funded teams rapidly advancing audio AI, a field where big labs lag. Kyutai’s Moshi is the first real-time full-duplex conversational model, latency ~160 ms, built in a four‑person/ nonprofit setup, using two-stream (full duplex) audio and backchanneling. Gradium turns Kyutai’s research into production, raising ~$70M. Core tech includes Mimi, a neural audio codec; AudioLM-inspired token compression; and Hibiki, real-time voice translation in the speaker’s voice. The piece argues audio requires domain expertise and clever, scalable ideas, not just bigger compute.

Pocketblue provides Fedora Atomic images for mobile devices (Xiaomi Pad 5/6 and OnePlus 6/6T). It’s a work-in-progress; installing will erase device data. The repository includes installation guides, technical details, and tools like toolbox, Firefox mobile as a flatpak, and fex-emu for running x86 apps on ARM, plus links to related Fedora Mobility projects.

Peter Steinberger announces he is joining OpenAI to make AI agents accessible to everyone. OpenClaw will become a foundation—open, independent, and open-source—supported by OpenAI. He aims to build user-friendly, safe agents with access to the latest models and grow OpenClaw as a data-owning foundation for thinkers and builders. After meetings in San Francisco with major labs and unreleased research, he says the shared vision with OpenAI makes the move timely. The goal is broader deployment of agents, not building a large company.

GNU PIES (Program Invocation and Execution Supervisor) starts and controls external programs called components. Each component runs in the foreground; PIES reads the component list from a configuration file, starts them, and then runs in the background to manage their execution. If a component terminates, PIES normally restarts it, but it can also trigger other actions such as sending notifications or launching additional programs. It can function as an init daemon. Configuration may be /etc/inittab or a native GNU PIES config, with a rich control interface for monitoring.
