The Art Institute of Chicago’s public API defines a boolean field named **has_not_been_viewed_much** for each artwork record. According to the source code, the field is set to true when the artwork has been viewed fewer than 200 times on the museum’s website since January 1 2010; otherwise it is false. This metric provides a simple indicator of low online engagement for individual pieces, allowing developers or analysts to filter or flag artworks that receive minimal visitor attention. No additional criteria or context for the low view count is supplied beyond the numeric threshold.

Organic Maps is an open‑source, privacy‑focused offline mapping and GPS application built on OpenStreetMap data, created by the developers of Maps.Me and released under the Apache License 2.0. As of December 2025 the app has achieved 6 million installs. It provides fully functional offline maps for hiking, cycling, walking and driving, including contour lines, elevation profiles, peaks, slopes, and metro/subway layouts. Core navigation features comprise turn‑by‑turn routing with voice guidance, CarPlay/Android Auto support, fast offline search, and import/export of bookmarks in KML/KMZ, GPX, and GeoJSON formats. The app offers dark mode, Wikipedia snippets for notable locations, and small storage footprints per region. Privacy claims include the absence of ads, tracking, data collection, registration, push notifications, or “phoning home,” and verification by Exodus Privacy and TrackerControl. Funding is community‑driven; donations and institutional grants support development. Distribution channels cover major app stores (App Store, Google Play, Huawei AppGallery) and F‑Droid/Obtainium for open‑source releases.

The author describes how Castro’s attempt to differentiate via personalized, human support proved ineffective. Support requests fall into several categories: pricing complaints, which rarely improve sentiment despite explanations or extended trials; bug reports, ranging from reproducible issues to vague “it doesn’t work” messages, where most replies are unsatisfying and telemetry provides better data; nuanced questions (e.g., App Store or subscription edge cases) that constitute less than 1 % of emails but can be resolved quickly; repeated confusion about podcasts, platforms, or system behavior, leading to “pathological” customers who demand disproportionate attention without increasing revenue; and feature requests, which often reflect a vocal minority and risk alienating broader users if implemented. The conclusion is that extensive, individualized support does not build loyalty and can be counter‑productive. Castro now limits responses to brief acknowledgments and focuses resources on product improvements, following the standard industry practice of prioritizing tangible fixes over extensive personal interaction.

The paper “Does Code Cleanliness Affect Coding Agents? A Controlled Minimal‑Pair Study” investigates whether the cleanliness of source code—its formatting, naming conventions, and structural organization—has measurable effects on the performance of automated coding agents. It employs a controlled experimental design in which code snippets are presented in carefully constructed minimal pairs that differ only in cleanliness attributes, allowing isolation of the variable under study. The methodology includes quantitative evaluation of agent outputs, error rates, and processing efficiency across the paired conditions. Results are reported in terms of statistical significance and effect size, indicating the degree to which code cleanliness influences agent behavior. The study contributes empirical evidence to discussions on best practices for code preparation when interacting with automated programming tools.

The post notes that while software personalization is common, hardware personalization is lagging: manufacturers ship sealed devices despite the rise of inexpensive, mass‑produced wearables and microcontrollers (e.g., ESP32 boards at ~$7, 600 M+ wearables annually). Emerging agents require direct sensor access (camera, microphone, motion, location), which resides on edge devices rather than in browsers, creating demand for bespoke software on many single‑purpose gadgets. Current open‑source initiatives (Pebble, Meta, Mentra, Google XR Blocks) expose device platforms via web technologies, but developing for embedded hardware still requires C++, SDKs, manual drivers, and complex toolchains. GEA proposes raising the software abstraction layer: a single codebase written with web‑style practices is compiled ahead‑of‑time to native code for microcontrollers, embedded Linux, phones, or desktops, eliminating the need for deep firmware expertise. The author stresses that hardware manufacturing, certification, and supply‑chain challenges remain, but the software barrier can be lowered, allowing more developers to write applications for personalized hardware.

- In September 2022 the author enrolled in the University of London’s fully‑remote BSc Computer Science delivered via Coursera; admission was through Performance‑Based Admission (pass Intro to Programming I and a math module). - Tuition is paid per module (£823 ≈ A$1,600); total cost ≈ £17 k (A$33 k) over 3.5 years, with some modules replaced via Coursera‑recognised prior‑learning certificates, reducing time and expense. - The program requires up to four modules per session, completed within six years; the author averaged three–four modules per session, finishing in about 3 years, with intensive periods of midterm and exam work. - Assessments consist of mandatory assignments and proctored exams (Inspera); grade turnaround can take up to three months, and resits may be delayed up to a year. - Coursework covers typical CS topics (programming, OOP, software design, signal processing, ML) with projects such as audio visualisers, JavaScript games, a JUCE DJ simulator, evolutionary algorithms, and a breast‑cancer detection classifier on Apple Silicon. - Student community interaction occurs mainly via a Coursera Slack workspace; peer support and shared resources (notes repos, difficulty spreadsheets) are common. - The university’s AI policy (2025) classifies undisclosed LLM‑generated work as contract cheating, defining three levels of permissible AI use in assessments. - Key practical tips: start assignments early, use iterative submissions, maintain a checklist for uploads, prioritize “blocker” subjects, and follow Slack pins for procedural guidance.

Homegames is a free, open‑source browser‑based game platform that lets users play, create, and share games without needing an account. Key features include a built‑in code editor, live multiplayer preview for testing changes, and an asset manager for uploading or creating files directly within the studio. Games can be published publicly or kept private. All components—platform code, games, and website—are released under GPL‑v3, allowing anyone to read, fork, or self‑host the entire stack, including the API. The project emphasizes preservation by ensuring games remain accessible even if the original site disappears. Development began in 2018 as a largely solo side project and continues under the same open‑source licensing model.

The post discusses Sony’s plan to stop producing physical game discs after January 2028, arguing that the issue is not the loss of disks but the erosion of ownership rights. It outlines three dimensions of ownership: - **Tradeability:** Physical copies allow resale, lending, and swapping, which digital licenses prohibit; the author cites past consumer backlash against Xbox One’s online‑verification model. - **Preservation:** Physical media enable users to archive and emulate games, protecting titles from delisting, store closures, or future hardware that blocks dumping. The author warns that a disk‑free, highly secured console could render pre‑2024 games inaccessible. - **Consumer options:** Physical games provide price flexibility, rentals, and used‑market purchases, whereas a digital‑only ecosystem confines buyers to a single storefront’s pricing and policies. The article contrasts consoles with PC, noting that PC users can obtain DRM‑free copies from multiple stores (e.g., GOG, itch.io) and retain the ability to back up, modify, and run games offline. It predicts a shift toward subscription‑only models similar to Netflix, urging support for DRM‑free and preservation initiatives.
