Marcin Dudek details a WordPress site flooded by 288,493 POST requests to /xmlrpc.php in 24 hours from a Singapore DigitalOcean IP, using system.multicall to try hundreds of credentials per request. Cloudflare cache hit rate collapsed to 0.8% (dynamic, uncached requests). The attack was stealthy because it didn’t spike uptime; cache rate is a better alarm. Fixes: block /xmlrpc.php at the edge with a Cloudflare WAF rule, and disable xmlrpc in WordPress (e.g., WP Multitool Frontend Optimizer or code). XMLRPC is largely unnecessary in 2026; use REST and restrict if Jetpack is used. Proactive monitoring recommended.

BBC Eye's undercover film at THQ Taunsa Hospital shows syringe reuse, unsafe injections, and injections without gloves, with shared vials. Some 331 children in Taunsa tested HIV between Nov 2024–Oct 2025; many cases list contaminated needles as the transmission mode. Although the hospital superintendent was suspended in March 2025, footage suggests unsafe practices continued eight months later. UNICEF/WHO mission found infection-control failures; officials say evidence linking THQ Taunsa to the outbreak isn't conclusive. Systemic pressures—high demand for injections and shortages—drive risk, echoing Ratodero and Karachi outbreaks.

Lucas Gerads describes experiments using Claude Code for hardware development. Prompting Claude to design circuits in natural language works only for simple designs; the model benefits from immediate feedback when given access to a SPICE simulator and an oscilloscope. This enables effective validation of circuits and data analysis, especially after tedious normalization and alignment. A simple demo illustrates the approach and its scalability. Key lessons: Claude can't infer your physical connections; avoid stale data; save data to files; provide explicit pinout maps and a Makefile with build/flash/ping/erase commands for Claude to reuse. Repos include lecroy-mcp, spicelib-mcp, rc-filter-demo-files.

TechCrunch writer Amanda Silberling examines how hype around Geese and other artists is manufactured, revealing Geese worked with Chaotic Good to create fake social accounts and campaigns to simulate a trending song. The piece argues that marketing tactics—creator farms, mass posting, and coordinated comment fleets—are widespread in music and startups (e.g., Phia) and reflect a broader trend of engineered virality. It also notes industry plants like Katseye and documentaries about PR in pop. The piece questions authenticity, ethics, and where fans draw the line between organic hype and manipulation.

“Wretches, Speak Evil of Me”: Goethe and Schiller’s Xenions recounts the 1797 joint verse attack by Goethe and Schiller on their critics in Xenions, published in Schiller’s Musen-Almanach. In 675 distichs (mixed hexameter and pentameter), they lampoon Enlightenment defender Nicolai, Fichte, and other opponents, while also reflecting on Romanticism’s artistic and moral challenges. The English edition (Paul Carus, 1896) selects notable pieces; backlash followed with counter-Xenions and later parodies, including Faust’s “Proktophantasmist.” The essay situates Xenions within Balladenjahr and Romantic polemics.

The Passive Income trap argues that a generation of would-be entrepreneurs bought into a salvation narrative of passive income, fueling a vast ecosystem of dropshippers, affiliate sites, and online courses that prioritized the dream over real value. Using Jade Roller Guy as a cautionary example, Westenberg shows how chasing 'systems' that earn money while you sleep detaches from actual customer needs, flooding the internet with low-quality content and failed ventures. Real money comes from solving real problems, delivering value, and persisting—work, care, and time—not passivity.

Open Culture argues Orwell’s 1984 envisioned a mechanized ‘versifier’ in the Ministry of Truth that churns out prole entertainment—dull newspapers, cheap novellas, sex-soaked films, and sentimental songs crafted by a kaleidoscopic machine. Winston even overhears a hit song produced without human input. The piece then links this to today’s AI‑generated ‘slop’: high‑volume, low‑effort content that floods the internet because it’s popular. It suggests Orwell was prescient about mass culture’s direction, even as real AI breakthroughs came decades later.

Newly unsealed records in California’s 2022 antitrust case allege Amazon used price-tracking tools and Buy Box suppression to pressure independent sellers to keep prices higher than competitors, masking higher overall prices. The documents—emails, depositions, and presentations—show cases where sellers lost Buy Box or faced suppressed listings when undercut elsewhere (even by a penny, against Walmart), and where prices on other sites like Temu rose as a result. Amazon denies wrongdoing, claiming it promotes low prices. The trial is set for January 2027; Amazon remains the dominant U.S. online retailer.

CBP will launch CAPE, a phased refund system for roughly $166 billion in tariffs the Supreme Court ruled unlawful, consolidating refunds into one electronic payment with interest. The initial phase covers recent imports; rollout will proceed in stages. As of April 9, about 56,500 importers had filed for refunds totaling about $127 billion. A $2.9 billion subset may be processed manually to avoid overload. Over 330,000 importers paid tariffs on about 53 million shipments. Small importers fear refunds may not justify costs; Trump denounced the ruling and separately imposed a temporary global tariff now under court challenge.

At Duke's new Masters in Game Design, Development, and Innovation, instructors pair Unreal Engine lessons with Playdate, Panic’s tiny handheld, to accelerate hands-on learning. The Playdate’s simple, portable hardware—1‑bit display, crank controller, free SDK, browser-based Pulp builder, and a simulator—lets beginners prototype playable games within hours. Intro classes produced titles like Owl Invasion and Owlphabet Soup, built around the crank. More than 50 Playdates have been issued, and Duke’s experience helped launch Playdate for Education to broaden access.

AutoProber is a self-contained, source-available stack for agent-driven flying-probe automation. It coordinates a GRBL-based CNC, USB microscope, oscilloscope, and optical endstop to map targets, stitch frames into a target map, and present probe targets for approval before bounded probe motions. The web dashboard and Python apps control hardware and review probes. Safety is central: Channel 4 monitoring, no automatic recovery, and strict lab-use guidelines. The repo includes apps, dashboard, CAD/docs, and licenses (PolyForm Noncommercial 1.0.0). Intended for authorized, safety-conscious lab experiments.

AI infrastructure faces scarcity as GPU rents rise (Nvidia Blackwell at $4.08/hr, +48% in 2 months). CoreWeave hikes prices 20% and extends minimum contracts 1→3 years. Anthropic limits its newest model to about 40 organizations. Access to bleeding edge is gated by capacity and security. Five hallmarks: relationship-based selling, AI to the highest bidder, availability but slow, inflationary commodity, procurement/margin discipline; plus forced diversification to smaller models or on‑prem. The age of abundant AI is over and will be for years.
