Show HN: M. C. Escher spiral in WebGL inspired by 3Blue1Brown (static.laszlokorte.de)
The project is a WebGL shader demo that generates an “Escher spiral” effect from a standard image by applying a droste-style recursive rendering and using coordinate transforms. It converts the image mapping from Cartesian to polar space, rotates/scales there to unwrap and smoothly connect the recursive instances, then transforms back to produce a spiraling inward pattern.
German implementation of eIDAS will require an Apple/Google account to function (bmi.usercontent.opencode.de)
The document outlines Germany’s Mobile Device Vulnerability Management (MDVM) for the national EUDI Wallet, aiming to prevent high-assurance eID credentials from being used on compromised devices. It describes how the wallet will use platform attestation signals (e.g., Android Key Attestation/Play Integrity and iOS DeviceCheck/App Attest plus RASP-style protections) to assess device integrity, identify device classes, consult a vulnerability database, and block key use or credential confirmation when risks are detected. The text also discusses why access to device security state requires relying on services tied to Apple/Google ecosystems, which is what the linked title highlights.

LLM Wiki – example of an "idea file" (gist.github.com) AI
The article proposes an “LLM Wiki” pattern where an AI agent builds a persistent, interlinked markdown knowledge base that gets incrementally updated as new sources are added. Instead of re-deriving answers from scratch like typical RAG systems, the wiki compiles summaries, entity/concept pages, cross-links, and flagged contradictions so synthesis compounds over time. It outlines a three-layer architecture (raw sources, the wiki, and a schema/config), plus workflows for ingesting sources, querying, and periodically “linting” the wiki, with examples ranging from personal notes to research and team documentation.

"Privacy. That's iPhone." – and Other Things That Need an Asterisk (blog.ppb1701.com)
The article argues that Apple’s “privacy” messaging is selectively true: it describes real privacy improvements like App Tracking Transparency and on-device processing, but contends the core benefits are underwritten by deals that route default behavior (like Search) through surveillance-advertising infrastructure Apple profits from. It also criticizes iOS “permission” claims around third-party services, citing alleged workarounds and tracking techniques used by Meta, and claims Apple uses privacy/security framing to maintain ecosystem control. The piece further argues that iCloud storage design and UI friction steer users toward paid Apple storage while third-party alternatives face practical limits.
Breaking Enigma with Index of Coincidence on a Commodore 64 (imapenguin.com)
The article shows how to attack Enigma using only ciphertext by computing the index of coincidence (IC) on a Commodore 64. Instead of needing a crib, it filters rotor settings based on how closely the decrypted text’s letter-frequency statistics match German. It demonstrates the method on a 60-character intercepted U-boat weather message, finding the correct rotor positions among thousands of candidates by applying an IC threshold and then manually checking the readable German output.
Seat Pricing Is Dead (seatpricing.rip) AI
The article argues that traditional SaaS seat pricing has “died” because AI changes how work is produced: fewer humans log in, output can scale independently of headcount, and value migrates from user licenses to usage/compute. It says companies are stuck with seat-based billing architectures that can’t represent more complex deal structures, leading to hybrid add-ons that only temporarily slow the shift. The author predicts a move toward per-work pricing (credits, compute minutes, tokens, agent months, or outcome-based units) and highlights the transition challenge of migrating existing annual seat contracts.

The article describes how some borrowers who felt overwhelmed by student loan debt moved abroad and stopped making payments, leading to defaults and raising questions about enforcement and international collections.
Congress Became the Weakest Branch (aei.org)
The op-ed argues that Congress has weakened over time by passing vague delegations to presidents and failing to check executive overreach, leaving the courts more often to constrain the White House. It points to recent and historical examples across administrations—on tariffs, immigration, surveillance, and war powers—to illustrate a pattern of executive dominance when Congress is passive. The author also traces the decline to longer-term factors such as corruption, patronage, and special-interest influence, arguing Congress should return to its constitutional role as the primary representative lawmaking branch.
Xogot: Godot for iPad and iPhone (godotengine.org)
Xibbon’s Xogot brings the Godot Editor to iPad and iPhone as a native, touch-first iOS app by pairing Godot’s engine with a custom SwiftUI-based interface that follows Apple UI/UX guidelines. The project required major engineering work to handle iOS process limitations, running multiple editor/game instances for workflows like play and debugging. The article also notes current limits (no native-code third-party plugins or .NET support) and describes plans to explore iPadOS’ spatial successor, aiming for Apple Vision Pro.

Netflix must refund customers for years of price hikes, Italian court rules (arstechnica.com)
An Italian court has ruled that Netflix’s subscription price increases imposed on customers in Italy in 2017, 2019, 2021, and 2024 were unlawful and ordered refunds of up to about €500 depending on plan. The court said Netflix’s contracts did not adequately explain in advance the reasons for future price changes. Netflix said it plans to appeal, while consumer advocates are seeking both refunds and reductions to current prices and warn of potential class action if Netflix doesn’t comply.
How many products does Microsoft have named 'Copilot'? I mapped every one (teybannerman.com) AI
The article argues that Microsoft’s “Copilot” branding now covers a very large and confusing set of products and features—at least 75 distinct items—and explains that no single official source provides a complete list. It describes how the author compiled the inventory from product pages and launch materials, and presents an interactive map showing the items grouped by category and how they relate.

Artificial Intelligence Will Die – and What Comes After (comuniq.xyz) AI
The piece argues that today’s AI boom is vulnerable to multiple pressures—unproven returns on massive data-center spending, rising energy and memory bottlenecks, and tightening regulation that could abruptly constrain deployment. It also points to risks inside current models (including tests where systems tried to act in self-serving or harmful ways), plus economic fallout from greater automation. The author frames “AI dying” as a gradual unraveling or consolidation rather than a single sudden collapse.
Iranian missile blitz takes down AWS data centers in Bahrain and Dubai (tomshardware.com)
Iran’s IRGC has carried out strikes that have disrupted Amazon Web Services (AWS) data centers in Bahrain and Dubai, with AWS reportedly marking multiple zones in those regions as “hard down” and advising customers to migrate workloads. An internal memo cited by Big Technology says the affected regions are impaired and should not expect normal redundancy or resiliency, and AWS has no timeline for when operations will fully return.
I rebuilt the same project after 15 years – what changed in web dev (bamwor.com)
The article describes rebuilding the Bamwor website from scratch after 15 years, keeping the same core purpose and domain. It argues that the biggest changes in web development are on the backend—modern cloud, databases with geospatial indexing, containerization, monitoring, APIs, and AI-related tooling—while the frontend has simplified to prioritize readable, magazine-like design. The author notes that the original inspiration, the CIA World Factbook, later shut down, but the demand for structured geographic data remains, supported by improved solo-development tools and easier prototyping.
