Overview of maze-generation algorithms and variants, with notes on performance and tunability. The article lists common methods: Recursive Backtracking (and a parallel-seeds variant), Eller's, Kruskal's, Prim's, Recursive Division (including “Blobby” subdivision), and various thresholds. It then covers Aldous-Broder and Wilson's algorithms, plus Houston's hybrid (faster but not perfectly uniform). Also includes Hunt-and-Kill, Growing Tree and Growing Binary Tree with tunable parameters (random/newest/oldest/middle), Binary Tree, and Sidewinder. A link to Mazes for Programmers and the GitHub demos is provided; changes require a reset.

Rahim Alwer narrates a six-year journey from Vime to Vidstack, building a modular video-player stack that moved from widgets to web components and then a Radix-like component library. Despite early success (9B CDN requests, 7M npm downloads, 6.2k GitHub stars, 200+ releases), friction—state bloat, cross-framework maintenance, and web component limits—blocked progress. In 2025 he joined Mux, and Video.js v10 is the convergence: framework-native, composable APIs, and a compiler that outputs to multiple frameworks with modular skins. It promises a true, scalable, reusable video platform; alpha arrives early February.

Recall.ai describes diagnosing and fixing a rare segfault in its meeting-bot audio pipeline caused by an old VisualOn AAC encoder (voAACEnc) in libvo-aacenc. The crash occurred in pow2_xy during fixed-point math when avgEn could dip below minEn due to precision loss in Div_32/mul. The team captured core dumps, reproduced the state, and traced the root cause to a bug that upstream fixed over a decade ago but which wasn’t released to the GStreamer plugin. They patched with a guard: after computing avgEn, clamp to minEn. They recommend replacing the encoder with a modern alternative.

Microsoft confirmed to Forbes that it will provide the FBI access to BitLocker encryption keys stored in its cloud if a valid legal order is issued. Windows 11’s mandatory Microsoft Account backs up BitLocker keys to the cloud by default, a feature that helped law enforcement in Guam in 2025. Keys are sometimes unencrypted in the cloud; users can disable cloud backup and keep keys locally. Microsoft receives about 20 FBI key requests annually; privacy advocates warn this creates a potential backdoor. Users can check and delete keys via their Microsoft Account page.

Estimating software work is largely futile because most work is unknown and only known work can be estimated; estimates are political tools for management, not engineers. Instead of asking how long something will take, assume the deadline the organization wants, then explore which approaches fit that window and what risks matter. The author outlines a practical method: gather political context, consider multiple approaches that meet the time box, present a risk-based plan rather than a single duration, and only declare impossibility when the effort is truly unattainable. Trust is essential for this approach.

Open source 'Just Fork It' is a critique: while forking OSS is technically trivial, sustaining a project is social work—trust, governance, maintenance. Forking fragments communities, duplicates effort, and erodes value and history; many forks fail not due to code but social surface area. The term can mask power dynamics and shield maintainers from accountability. A healthier path is inclusive collaboration, conversations with dissenters, and stewardship of shared infrastructure—incremental changes over dramatic exits. Forks have a place as a last resort, not default.

World Air Quality Index provides a real-time, global map of air quality (AQI) for more than 100 countries, with categories from Good to Hazardous. It aggregates data from hundreds of stations, offers forecasts, historical data, and an API, and supports region- and language-based views. The platform encourages user-contributed GAIA monitors. Data are unvalidated at publication and may be amended; sources include OpenWeatherMap, MaxMind, GeoNames, Copernicus, and OpenStreetMap.

I’ve been using GitLab for my private projects for years after it offered free private repos when GitHub charged. The workflow is built around GitLab: built-in Container Registry for images (no Docker Hub), and CI/CD via .gitlab-ci.yml with versioned pipelines and optional manual deploys. Shared runners cover most needs, with easy options to run a private runner. Docs are extensive but sometimes overwhelming. Speed in the UI is not great and there’s feature overload, yet many features are handy. I keep private work on GitLab and public work on GitHub.

SQLite can efficiently handle both large, complex queries and many small ones since it runs in-process, avoiding IPC overhead. The article argues N+1 queries are not a problem for SQLite and can aid maintainability. Using Fossil’s timeline as an example, a page may run a single large timeline query plus dozens of per-item queries; overall latency for a 50-entry page is typically under 25 ms. Applications can choose either approach as appropriate.

Firebase and Google Cloud unveil Firestore's new Pipeline operations and a reworked, more expressive query engine in Firestore Enterprise edition. The engine supports over a hundred new features, including multi-stage queries, arbitrary aggregations, array unnesting, map operations, and regex matching, with optional indexes. A recipe-tag example shows unnesting tags to compute popular tags. Pipeline ops are available now in Android, iOS, web, and Admin SDKs; Flutter/Unity/C++ coming. Enterprise edition offers configurable indexing, different pricing (data chunks for reads/writes; free write tier), and export/import migration from Standard edition. Standard edition remains, but lacks Pipeline support.

modetc is a Linux kernel module that transparently rewrites file paths so programs can access relocated dotfiles while keeping their original paths. Example: ~/.ssh can be redirected to ~/var/lib/ssh. Configurable via module parameters (homedir, default_rule, rules_file, debug) and a rules file with tab-separated match/replacement lines (up to 16 rules; comments allowed). Runtime control via /proc/modetc (e.g., pause). Built with Nix (nix-build), loaded with insmod; testable in a VM. Uses kprobes in the VFS to modify kernel-space path arguments. Linux-only, GPL-3.0. Latest v0.1.3 (2026-01-23).

Cosmic Odometer is a client-side Space Travel Calculator that sums motion from Earth's rotation, Earth's orbit around the Sun, the Sun's motion around the Milky Way, and the Galaxy's motion relative to the cosmic background to estimate total distance since birth. It shows current totals, straight-line displacement, Moon trips, solar-system laps, and progress toward 1 light year. Speeds: rotation ~1,600 km/h; Earth around Sun ~107,000 km/h; Sun around Galaxy ~792,000 km/h; Galaxy relative to CMB ~2.1 million km/h. Privacy: calculations stay on-device. Created by @nemo7299.
