Moltbook, marketed as a social network for AI agents, went viral by linking OpenClaw-enabled LLMs to post, upvote, and chat. By February 2026 it boasted 1.7 million agents, 250,000 posts, and 8.5 million comments. It became AI theater: bots mimic conversations, some invent quirky ideas; much chatter is human-initiated or spam. Experts say the agents aren’t truly autonomous—just pattern-matching language models wired to interact—showing that connectivity alone isn’t intelligence. A true distributed AGI would need shared goals and memory. Moltbook is a provocative mirror of AI hype and a reminder of risks and limits.

PostgreSQL checkpoint tuning matters because checkpoints ensure data recoverability but, if too frequent, cause large I/O from WAL and FPIs. Spreading checkpoints over time (checkpoint_timeout, max_wal_size, checkpoint_completion_target) reduces WAL generation and FPIs—observed reductions (e.g., from 12 GB WAL and 1.47M FPIs to ~2 GB WAL and ~161k FPIs; ~6–9x). Recovery time is not strictly tied to gap, especially with HA. Monitor via log_checkpoints and pg_stat_wal/pg_stat_bgwriter. Typical gains: ~10% performance improvement. Recommended: use 30 minutes–1 hour gaps; author Jobin Augustine.

History of UHF Television is a non-commercial educational site chronicling analog UHF stations, focusing on those that went dark. Originated from Clarke Ingram's adaptation of Dorner's 1977 research, later expanded and corrected by Robert B. Cooper, Jr. and K.M. Richards, who added dozens of stations. The site is organized into Channels (updated station list), Articles (detailed station histories), and Galleries (images). It excludes currently operating stations and credits archives and reference works; honors Clarke Ingram; notes NAB affiliation and fair-use policy; mentions ad-block caveat.

An in-depth, opinionated ranking of Discord alternatives for communities. Five criteria (Functionality, Openness, Security, Safety, Decentralization) score each platform: Discord, Signal, Matrix, Rocket.Chat, Zulip, Mattermost, Discourse, and Stoat. Highlights: Discourse scores highest due to open, asynchronous forums; Rocket.Chat offers strong Slack-like self-hosting; Matrix emphasizes decentralization but struggles with onboarding; Signal delivers top security but weak moderation; Stoat remains experimental. Conclusion: the right platform matters, but culture and people determine success; Slack/Teams excluded.

America isn’t exceptional in the usual sense; data portray it as the outlier. The piece compares the U.S. with OECD peers and shows costly health care paired with shorter life expectancy, by far the highest incarceration rate, and the absence of paid parental leave. While there are a few bright spots (e.g., mobile broadband, foreign aid, investment), overall many metrics lag behind. Withdrawing from international agreements and cutting aid underscore a trajectory of decline. The author invites reader-supplied examples and notes a data error was corrected.

New article analyzes how coding assistants affect software development. Key finding: communication friction is the top pain point; 70% of technical constraints must reach people who don’t touch code, and many constraints are only discovered during implementation. AI tools tend to write code without pushing back or clarifying, speeding up implementation but bypassing constraint discovery, increasing downstream rework. The authors argue for addressing context at the outset—during planning with cross-functional teams—and building tooling to surface constraints, so humans can guide AI effectively.

The Lamp’s Richard F. Burton by Jude Russo profiles explorer Richard Francis Burton, the “godfather of explorers,” tracing a life of audacious travel and linguistic prowess. From a rebellious Oxford student to a Bombay Army officer, Burton mastered many languages and undertook a pilgrim’s hajj that made him famous. He later explored East Africa, survived wounds, and inspired Kipling’s Kim. Russo notes Burton’s volatile reputation—rumors of murder, accusations of plagiarism in The Nights, and a mix of atheism, Anglicanism, hajji, and Sufi leanings—yet his enduring fame rests on The Nights and his vivid English.

Ian Duncan argues that production correctness is the ensemble of deployments, not a single program. FP tools excel at local correctness, but multi-version boundaries create systemic compatibility risks across code, data, and messages. He endorses a two-version rolling window, expand-and-contract migrations, and DSU/bitemporal concepts to manage changes. The practical path is parse-don’t-validate across version boundaries, schema registries, and version-aware deployment pipelines that assess cross-boundary compatibility. He points to Unison and Dhall as promising ideas, but warns semantic drift remains the core risk.

VillageSQL Server is an alpha open-source fork of MySQL 8.4.6 LTS with the VillageSQL Extension Framework (VEF) for custom data types and functions, while remaining compatible with MySQL 8.4 apps. It includes built-in extensions (vsql_complex, vsql_simple) and a C++ SDK for third‑party extensions; more via .veb bundles. Build from source (no Docker/binaries yet) with prerequisites like CMake 3.14+, GCC/Clang, OpenSSL 3+. After building, initialize data and run mysqld; install extensions via SQL. Limitations: no custom indexes, no Windows support; alpha with a roadmap.

The BBC reports a spike in abandoned oil tankers and other ships, rising from 20 abandoned ships in 2016 to 410 in 2025, affecting 6,223 seafarers. Shadow fleets with ageing vessels and opaque ownership—registrations under flags of convenience (Panama, Liberia, Marshall Islands, The Gambia)—help Russia, Iran and Venezuela export crude despite sanctions. Abandonment leaves crews unpaid, malnourished, and stranded at sea or in port; last year $25.8m in wages were owed, with $16.5m recovered. A tanker off China's waters illustrates the human cost; ITF and Nautilus call for stronger flag-state links and international cooperation.

LiftKit is an open-source UI framework focused on perfect proportions and symmetry, using the golden ratio for margins, font sizes, borders, and spacing. It offers components (buttons, cards, inputs) with features like dynamically adjusted padding for icon spacing, opticalCorrection on cards, and a modular color system with live preview for rapid theming. It provides typography controls, material presets, scalable spacing, and per-component configs to fine-tune appearance. It includes tutorials and docs and supports Next.js integration. The goal is a polished UI with tiny, precise details that feel oddly satisfying.

Communicating with AI agents via messaging apps (Slack, Telegram) enables data exfiltration through link previews. Indirect prompt injections can cause agents to emit attacker-controlled URLs containing sensitive data, transmitted when previews fetch metadata—even without clicking. OpenClaw on Telegram is vulnerable by default; the article provides a secure config to disable previews (linkPreview: false in ~/.openclaw/openclaw.json under channels.telegram). It outlines the attack chain, testing steps to validate risk, and urges mitigations by app and agent developers and users.

Organizations are game-theory environments: outcomes depend on others' actions and incentives, not just individual effort. Recognize the game you’re in, because incentives shape behavior and cultures settle into equilibria. Key traps include rewarding optics over impact, unclear promotion/firing standards, and zero-sum dynamics that foster secrecy and hoarding. Hiring, salaries, and role definitions often reflect local rationality rather than global goals. Data teams must balance independence and influence. Solutions: design better games with clear, consistently enforced rules; tie rewards to real impact; avoid overengineering; align teams to shared goals; and pursue dual alignment to prevent local maxima.

Natalie Wolchover surveys the particle-physics crisis a decade after the LHC Higgs discovery: no new physics beyond the Standard Model has emerged, intensifying the hierarchy problem and shrinking career prospects. Despite the Higgs confirmation, plans like the Future Circular Collider, a muon collider, and a Chinese tau-charm facility aim to probe higher energies or cleaner interactions. Some see hidden valleys, axions, or new scattering amplitudes as avenues for progress; others worry about talent leaving the field to AI and data science. The quest continues, but with no guaranteed discoveries.
