Despite complaints about spam, the author extols email as magical and empowering. Sending quick notes to people who created things on the web leads to appreciation, clarifications, and meaningful exchanges. Receiving replies can feel like a global superpower—being able to reach anyone, anywhere, by mail. She prizes email’s simplicity and universality: plain text, personal font choices, and independent conversations. The piece ends by encouraging readers to email open-source projects or curious creators, which can spark conversations and brighten someone’s day.

WIRED reports Grammarly, now rebranded under Superhuman, offers an “Expert Review” AI that simulates input from living and deceased writers and scholars (e.g., Stephen King, Carl Sagan, William Zinsser) without their consent. The so‑called experts aren’t involved; a disclaimer says no endorsement. The tool appears to draw on their works, raising copyright and ethics concerns and prompting scholars to call it dehumanizing and unethical, akin to “reanimating” dead authors. Critics worry it misleads students and undercuts real expertise, amid Grammarly’s broader AI toolkit.

After four Tehran oil depots were struck, thick smoke and toxic air blanketed a city of about 10 million as flames burned overnight. Authorities warned to stay indoors, guard food, and avoid air-conditioning after rainfall due to acid rain fears. Residents described apocalyptic scenes—coughing, burning eyes, scarce masks, and soaring prices with fuel and basic goods in short supply. Some tried to flee; others stayed, feeling abandoned by the regime as the city faced health risks and potential water contamination amid ongoing strikes.

Grammarly’s “Expert Review” AI offers feedback “inspired by” industry experts, including Verge editors. The Verge tested it and found AI suggestions sometimes appeared as edits from editors like Nilay Patel or Sean Hollister without their permission. Some named experts had outdated titles; sources linked to spam copies or unrelated pages, and the UI could mislead by mimicking real comments. Grammarly says the feature provides suggestions inspired by experts, not endorsements, and directs users to their work. The Verge questions permission and accuracy in citing living or deceased figures.

mcp2cli turns an MCP server or OpenAPI spec into a runtime CLI with zero codegen. It discovers tools on demand, reducing token usage by avoiding full schemas in the LLM context (up to ~95% savings in tests). It supports MCP over HTTP/SSE and OpenAPI specs (JSON/YAML), with local caching, TTL, refresh, and CLI-like commands (--list, --help, --spec/--mcp, --pretty, --raw, --toon). It builds a uniform CommandDef, generates an argparse-based CLI, and dispatches HTTP requests or MCP tool calls. Works with any LLM, updates automatically when APIs change, no rebuild required.

Kawasaki Robotics has pursued humanoid development since 2015 with Kaleido, aiming for two‑legged, two‑armed work companions. Early prototypes faced leg rigidity, torsion, and heavy controllers; switching from E- to F‑controllers enabled a leaner humanoid. Kaleido debuted publicly in 2017 at iREX, then became fully untethered in 2019 with onboard batteries and weight‑reduction through magnesium, 3D‑printed parts, and in‑house resin components, plus custom light 6‑axis force/torque sensors for walking. In 2021, the Friends series offered a slimmer, home/care‑friendly design with AI conversational/gestural interaction. By 2023, real-time footstep adjustment improved stability. Future aims include remote operation and disaster response.

Piotr Migdał details reviving Chromatron, a 20-year-old laser-puzzle game, from WinXP/PowerPC to Apple Silicon and WASM using Ghidra and AI. After trying Claude Code/Opus 4.5, m2c, GPT-5.2/5.3-Codex, and PyGhidra, he rebuilt it in Rust with Opus 4.6 (Winit/softbuffer) for a near pixel-perfect result. The final build runs on Windows, Linux, and WASM; 307,199 of 307,200 pixels match; the last difference is a render-order edge and the font VGASYS. Lessons: model strengths, guardrails, references, and when to restart. Playable online now.

The article argues that AI-generated content has flooded social media, eroding authenticity and trust as algorithms chase engagement. Human voices are drowned by repetitive, shallow posts. RSS is proposed as a remedy: a decentralized, algorithm-free feed system enabling subscriptions to human-created sources, with content delivered directly and ad-free. Feeder is highlighted as a strong, open-source option; other readers like Feedly and Inoreader are also mentioned. The author envisions a future where self-curated RSS feeds decenter platforms and reclaim authentic information.

Dr. Drang analyzes UK Lotto odds (6/59 with a bonus ball) and explains you can’t simply multiply separate lottery odds. He derives: 6 matches ≈ 1 in 45,057,474; 5 matches ≈ 1 in 141,690; 4 matches ≈ 1 in 2,180; 3 matches ≈ 1 in 96; 2 matches ≈ 1 in 10.3. With the bonus ball, 5 matches + bonus ≈ 1 in 7,509,579; 5 matches only ≈ 1 in 144,415. Odds vary with tickets sold and prize structure; notes tools like binomial formulas in Mathematica and Python.

An extensive compilation of last statements by Texas death row inmates (1990s-2020s), listing dozens of individuals along with year of execution and their final remarks. The statements commonly express remorse, forgiveness, and faith in God or Allah, often addressing victims' families and loved ones; several inmates claim innocence or protest injustices in the conviction system; many invoke scripture or religious phrases; in some cases they address fellow inmates or staff; the piece documents the human, spiritual, and emotional dimensions surrounding capital punishment.

Lynn Fisher’s 2025 refresh journals a playful, low‑stress redesign of lynnandtonic.com that experiments with a fixed‑width content area (436px) scaled in real time as the browser resizes. Using a ResizeObserver, the site applies a dynamic scaleX transform based on the width change, clamped to avoid flips, and resets to its original width when resizing stops, with a subtle bounce transition. The effect works best around 436px and below 500px the layout becomes normal responsive again. The piece also covers typography, textures, focus styles, and reflections on annual refreshes.

The Mojave Phone Booth, a derelict payphone in the desert that sparked online fascination after a 1997 article and was shut down by PacBell in 2000, has been revived. Hacker Jered Morgan (Lucky225) announced that the number 760-733-9969 now works as a VoIP conference line, routed through an Asterisk server. There’s no practical caller limit beyond bandwidth; the number was legally ported to a CLEC after PacBell retired it. The revival honors the old social‑connectivity legend while enabling modern group calls.

The article explains /proc/self/mem’s “punch-through” writes, which can modify unwritable user memory and even executable code, used by tools like Julia JIT and rr. It analyzes hardware protections (CR0.WP and CR4.SMAP) and shows the kernel can bypass them by a software page walk: mem_rw uses get_user_pages_remote with FOLL_FORCE to find the backing frames, kmap maps them RW into the kernel, and copy_to_user_page writes data. Thus, memory permissions apply to virtual addresses, not physical frames, revealing how the kernel can override user-space protections.

AngstromIO-devboard is a tiny devboard (8.9×9 mm) based on the Attiny1616 (16 KB flash) with USB‑C power, I2C lines, and UPDI programming. It exposes SCL, SDA, PB2 (TX), PA3, +5V, GND, and UPDI. A dual CH340E programmer/debugger board provides UPDI programming and USB‑UART debugging; two USB‑C ports supply data and 5V. A CH32V003-based breadboard-friendly board adds a 4×5 charlieplexed LED matrix. Designs are panelized on EasyEDA; AngstromIO software is Arduino‑compatible, with libraries from SpenceKonde megaTinyCore.

Wall Street veteran Jim Paulsen argues that most of the US economy is already in recession, with GDP gains mainly powered by “new era” tech spending (AI, information processing equipment) while the “old era” economy struggles. Excluding new era investment, private real GDP rose only about 1% and created few jobs. New era spending grew ~14% in 2025 and dominates growth, widening the gap with traditional sectors. The contrast mirrors a Magnificent Seven vs. rest, suggesting GDP looks okay but 89% of the economy is not.

Azure WAF in Detection mode logs but does not block; requests reach backend. Defaults to Detection on new policies; tuning can take weeks, and many never exit, yielding a false sense of protection and alerts treated as noise. To fix: inventory modes with Resource Graph, enforce Prevention via Azure Policy, set a 2–4 week tuning window, codify exclusions in code, and switch to Prevention with a runbook. After switching, expect some legitimate blocks; Detection is not protection.
