The author argues against banning social media for under-16s, noting that harm claims rely on correlational evidence and lack clear proof of greater harm to children versus adults. They question replacement activities, impulse control, and brain development uncertainty, and point out that many harms affect adults too. They compare to bans on gambling and junk food that don’t target children exclusively. Regulation is portrayed as insufficient and a child-specific ban as politically convenient. If banning, it should be universal, not just for children.

Impeccable adds a frontend-design skill with typography, color, layout, motion patterns and 17 commands (e.g., /polish, /audit, /simplify) to turn AI output into refined designs. It bundles curated patterns and anti-patterns, a 3-part framework, and real examples (landing page, form UX, dashboard) showing before/after results. It includes cross-tool integrations (Claude Code, Cursor, Gemini CLI, Codex CLI) with step-by-step setup, cheatsheets, and FAQ guidance for installation and troubleshooting. The project is independently maintained by Paul Bakaus with voluntary donations.

Sean Barrett recounts the 1998 Looking Glass Thief software renderer, developed before hardware acceleration. The engine uses portal-and-cell visibility (no grid), with a BFS traversal of cells and portals; visibility is clipped to per-cell bounding octagons to reduce overdraw. It avoids a z-buffer, uses painter's algorithm with interleaved world and object rendering, and includes a BSP-based sort and a complex, temporal CSG model using sequential brush operations. Texturing uses a custom perspective mapper with 8-pixel spans and multiple mappers, plus clut-based portal coloring for effects like water. Object skinning was external; hardware acceleration was added later.

The article debunks Nvidia’s claim that a 1 GW data center’s rack busbars could need up to half a million tons of copper. With about 200 kg of copper per MW, a 1 GW rack would require roughly 200 metric tons, not 500,000. The figure likely meant half a million pounds (~226 tons) or is a unit error. While copper demand from data centers, grids, and EVs could rise 400k–800k tons per year, the “copper apocalypse” is an overblown headline. Long mine-build timelines support demand, but the 500k-ton number is a typo.

tprof is a Python 3.12+ targeting profiler that timestamps only user-specified functions, avoiding the overhead of profiling the whole program. Built on sys.monitoring with C timing, it adds no overhead to unmonitored code. It offers a comparison mode that prints deltas against a baseline, and a Python API (context manager/decorator tprof) to profile specific blocks. Install from PyPI; examples show before/after benchmarks and delta percentages.

Test and [ are tied to the same test(1) utility. [ is a separate executable that calls test and enforces a closing ] when invoked as [. FreeBSD showed explicit closing-bracket checking; GNU coreutils often builds /bin/test and /bin/[ as distinct programs with similar logic but different flags. On modern systems they may not be identical, yet the behavior is effectively the same. The takeaway: [ ... ] is a convenient alias for test, but be aware of implementation differences that can affect scripts or exams.

San Remo's packaging features a built-in pasta measurer integrated into the box, providing a one-serving portion to guide cooking, reduce waste, and eliminate the need for external measuring tools. Designed by Ian Lim, the "one box, one tool" concept simplifies dinner with no guesswork.

China’s wind and solar expansion is occurring at an enormous scale. The Yale Environment 360 piece notes that last year China installed more than half of the world’s new wind and solar capacity, and in May alone added enough renewable energy to power Poland, with solar panels rising at about 100 per second. Photographer Weimin Chu used drones to document the nationwide buildout—from crowded eastern cities with rooftop solar to vast western deserts—drawing on traditional ink‑painting aesthetics. The selection includes photos of solar and wind sites across Sichuan, Qinghai, Inner Mongolia, and more.

Z80 Membership Card is a pocket-sized, two-board microcomputer kit (in an Altoids tin) that lets hobbyists build a complete Z80/CP/M-80 computer. The Z80 Membership Card provides the CPU, 64K memory, monitor, and BASIC for standalone use; the Front Panel adds a hex keypad, 7-seg display, and serial I/O; the optional Z80-SIO card adds RAM up to 512K, a real UART, and an SD-card disk emulator. Includes CP/M-80 OS and disk images. Sold as bare boards or complete kits (around $80 for the full kit, $50 for Z80-SIO), with manuals and SD-card files.

Dylan Araps, the open‑source coder behind Neofetch, explains his abrupt internet disappearance and pivot to farming. After years of a sedentary, high‑tempo tech life, burnout and health decline pushed him away from the screen. A spiritual awakening sparked by reading the Bible led him to abandon vice, adopt a plant‑based, local, seasonal diet, and train physically, restoring his vitality. He and his family moved to Amphithea, Euboea, Greece, bought a small estate, and launched WILD, a natural farming venture. He also announces WILD.gr.

Raspberry Pi unveiled the AI HAT+2 ($130), with 8GB LPDDR4X RAM and a Hailo 10H, enabling standalone LLM inference while freeing the Pi’s CPU. It draws ~3W and delivers up to 40 TOPS INT8 (26 TOPS INT4 CV). In practice, the Pi CPU with 8–16GB RAM often outperforms the Hailo for LLM tasks, and RAM isn’t upgradeable on the Pi. The HAT’s strongest use is vision processing or as a development kit, not a primary LLM solution. Mixed-model inference is experimental and unstable.

Chrome 144 introduces the <geolocation> HTML element, a capability-specific, user-initiated way to obtain location data that replaces most JavaScript Geolocation API prompts. As a data mediator, it signals intent via a browser-controlled button, reducing boilerplate and avoiding silent blocks. It supports autolocate, accuracymode, and watch with an onlocation event, and degrades gracefully in unsupported browsers. The feature follows earlier <permission> experiments and will be followed by a dedicated <usermedia> element; fallback to the legacy API is possible if needed.

Tutorial on writing a bare-metal RISC-V program for QEMU virt. Explains boot flow (ZSBL, OpenSBI), 0x80000000 as entry, ELF use with -bios, and differences with -kernel. Demonstrates building a small program that writes 'hello' to UART at 0x10000000, using a linker script to place code at 0x80000000, and running via qemu-system-riscv64 -machine virt -bios hello. Shows simple, OS-free I/O and verification of output.

Rast is a system for detecting orthographical errors in Central Kurdish (Sorani). It uses K8, an 8‑bit Kurdish encoding designed to be efficient for non‑ASCII characters, with an optional footer for backward compatibility. K8 is used in Rast’s URL state and in the transport protocol. The transport streams errors as a header with error and detail counts, error positions, and then detail headers with title and description plus indexes mapping to errors. The title/description may be a cache index or human‑readable data already sent on the connection. Bit‑streaming was forgone for cost reasons; updates may follow.

Simon Willison previews Claude Cowork, Anthropic’s general agent UI built on Claude Code with a filesystem sandbox, showing end‑to‑end workflows and warning about prompt injections and sandbox security. He also covers Fly.io’s Sprites.dev, which combines developer sandboxes with a sandbox API for untrusted code: persistent VMs, checkpoints, SSH access, port forwarding, public URLs, and scale-to-zero billing, plus Skills integration. The newsletter includes his answers to questions about porting open‑source code with LLMs—ethical, legal, and licensing considerations—and reflections on how AI‑assisted development could reshape open source and tooling.
