Oxford economist Olivier Sterck proposes 'average poverty': the average time to earn $1 in international dollars. By this measure, the US has more poverty than Europe. In 2025, it takes 63 minutes in the US versus 26 minutes in Germany and about 31–34 minutes in France and the UK—a gap driven by rising US inequality. Since 1990, US inequality outpaced income growth, while poverty declined in most high‑income European countries. Mississippi’s 2024 GDP per capita is close to Germany’s, illustrating deep pockets of poverty within the US.

Zerobox is a lightweight, cross-platform sandboxing tool to run commands with strict file, network, and credential controls. It denies writes, outbound network, and most env vars by default, while supporting per-host secrets via a proxy that injects placeholders. It offers granular flags for reads/writes, networks, env vars, and secrets, plus a TypeScript SDK. Platform: macOS/Linux (Windows planned); ~10 ms overhead. Install via curl | sh or npm. Examples show sandboxed runs with restricted writes and networks.

Meta launches BOxCrete, an AI model for designing US-made concrete mixes, with foundational data open-sourced under MIT on GitHub. Using Bayesian optimization and adaptive experimentation, it speeds mix discovery, compares US-made versus foreign materials, and respects technical constraints. In Rosemount, MN, an AI-optimized mix with domestically sourced materials achieved full structural strength 43% faster and reduced cracking risk by ~10%, now qualified for broader use. Partnerships with Amrize, UIUC, and Quadrel drive domestic cement adoption. Meta aims an industry-wide shift to sustainable, U.S.-made concrete.

An engineer tries Microsoft Copilot and, despite initial reluctance, automates tedious tasks (scrum ceremonies, BRD reviews, email writing) and drafts weekly reports. He discovers Copilot exists in many forms—Microsoft 365 Copilot, Windows Copilot, GitHub Copilot, and Copilot Chat—leading to confusion about what is what. A coworker who inspired the experiment reveals he meant ‘Copilot’ as a generic AI helper, later correcting himself to Cursor, not Copilot. The piece concludes the Copilot ecosystem is sprawling and confusing, but AI tools can still be worth embracing if clarified and integrated thoughtfully.

Ars Technica revisits Wolfenstein 3D in 2026, noting its blocky 3D spaces, no in-game map, and archaic level/enemy design compared with modern shooters. While its level geometry and hit-scan enemies feel dated, the author highlights how well the game translates to one-handed mouse controls: moving with the mouse, left click to shoot, right-click to strafe, middle to open doors, enabling full one-handed play and faster traversal. The review also covers rough difficulty balance, score/lives system, and save mechanics that clash with modern expectations, but finds value in the historical significance and early FPS design seeds.

An apparent Persian-language numbers station began broadcasting on Feb 28, shortly after U.S.-Israel strikes on Iran. A man reads random numbers in Persian, followed by “tavajjoh” three times. The signal, which uses shortwave, drew amateur radio sleuths who debated its purpose and origin. On March 4 it was jammed by a bubble jammer, and the transmission moved frequencies. Analysts suggest it could be a Cold War–style numbers station using a one-time pad; theories point to the United States, Iran, Israel, or a psychological operation. Priyom traced the transmitter area to parts of Western Europe; origins remain unclear.

Agents Observe provides real-time observability of Claude Code sessions and multi-agent activity. It uses Claude Code hooks to capture events (tool use, prompts, subagents), streams them to a local/remote server (Docker or standalone), stores in SQLite, and serves a live React dashboard showing the full agent hierarchy, events, tool calls, and payloads. Install via Claude Marketplace or run standalone with Docker; start the server and view at http://localhost:4981 (or dev at 5174). It enables time-travel debugging, filtering, and historical session browsing.

Apple removed the Anything vibe‑coding app from the App Store and had previously blocked vibe‑coding apps like Replit and Vibecode, citing Guideline 2.5.2 that apps be self-contained and not download or execute code that changes features or functionality of other apps. Supporters say vibe coding lets users generate and debug apps on-device with AI, but Apple says it’s enforcing rules, not targeting a category. Xcode has begun offering autonomous coding features via Claude and Codex.

Collabora Productivity publishes a provocative post alleging The Document Foundation ejects Collabora staff and partners over governance concerns, naming several former and current contributors. After acknowledging the claim as an April Fool, the piece sets out Collabora’s plans: develop a lighter Collabora Office, keep Classic supported, move to self-hosted FOSS tooling with a new Gerrit, and keep contributing to LibreOffice where feasible. It invites developers to join and signals a renewed focus on digital sovereignty and FLOSS.

Tracing Apple’s randomness landscape from rand/random/rand48 to modern APIs, the post argues for prioritizing robust kernel- and library-backed RNGs. Old APIs are deprecated; /dev/random and /dev/urandom tie to Fortuna in XNU and aren’t as flexible. arc4random(3) uses corecrypto RNG (ccrng) and is fast, but can be kernel-privileged. getentropy(2) taps the kernel RNG directly (max 256 bytes) and is slow; CCRandomGenerateBytes (Common Crypto) provides a simple, cryptographically strong in-process RNG seeded by the kernel. SecRandomCopyBytes wraps CCRandomGenerateBytes. For non-cryptographic use, seed a local RNG with getentropy(2) or CCRandomGenerateBytes; for cryptographic needs, prefer CCRandomGenerateBytes (arc4random as alternative with caveats).

War on Iran fuels a renewables boom as Europe faces higher oil/gas prices and supply fears. Brent crude jumps over 50% to about $116/bbl, with the Strait of Hormuz closure and soaring European gas prices pushing households toward green energy. Across Europe, demand for solar, heat pumps, and EVs surges: UK heat pumps up 51%, solar +54%, EV chargers +20%; EV inquiries rise in France, Romania, Portugal, Poland; Norway EVs now outsell diesels. Analysts say renewables cut bills and boost energy security, even as some push North Sea drilling.

David Futrelle critiques Marc Andreessen for declaring “zero introspection,” arguing the stance erases conscience from his war- and surveillance-focused investments. Tracing self-examination back to ancient philosophy and biology, the piece contends introspection aids judgment and empathy. It flags Andreessen’s defense portfolio—Anduril, Shield AI, and American Dynamism—as evidence of a business model profiting from militarized tech, including deals with the UAE and Israel. The author portrays this as a calculated branding move that absolves accountability and reshapes Silicon Valley ethics.

AI has suddenly become more useful to open-source developers, helping to clean up legacy code, maintain abandoned projects, and modernize codebases. Experts like Linux kernel maintainer Greg Kroah-Hartman report higher-quality AI-generated reports and code assistance; tools such as ATLAS illustrate AI-assisted modernization. However, major legal and quality concerns loom: potential licensing issues when AI-modified code is released, AI 'slop' that can derail projects, and risk of drown in AI-generated spam PRs, with Linus Torvalds warning AI isn’t a substitute for understanding code. OpenSSF plans to support maintainers; by year’s end tools should be more reliable.
