Cardputer uLisp Machine is a handheld Lisp computer (ESP32-S3) with a 240x135 display, 56-key keyboard, SD card, and 1.5 MB flash for Lisp workspace. It runs uLisp (a subset of Common Lisp) with ~200 functions, supporting integers, floats, strings, lists, graphics, and simple extensions. The editor has parentheses matching and autocomplete. Firmware is installed via the M5Stack core in the Arduino IDE; Mac USB boot issues are noted. Cardputer-specific extensions include get-key, read-pixel, and save-bmp; source is on GitHub.

Facing AI overload, a growing movement seeks an analog lifestyle to slow down and reclaim tangible tasks. Offline hobbies are booming: Michaels reports 136% more searches for analog crafts and an 86% rise in guided craft kits in 2025, with yarn kits up 1,200%. CNN's Ramishah Maruf tries living like the '90s for 48 hours, ditching devices, using a landline and film photos, and joining knitting circles. Proponents say going analog cuts doomscrolling and data exposure, not technology, while many still keep some digital habits. It’s a broader cultural shift toward mindful, hands-on living.

Stirling Cycle Machine Analysis is a self-contained learning resource by Israel Urieli offering MATLAB-based simulations for single-phase piston/cylinder Stirling machines. It extends the 1984 Stirling Cycle Engine Analysis book with updated MATLAB m-files (from FORTRAN) for thermodynamics, heat transfer, and friction, including ideal isothermal and adiabatic analyses and a simplified heat-exchanger model. It covers Alpha machines (Sinusoidal drive, Ross Yoke/Rocker-V), various heat exchanger types (tubular, annular gap, slot) and regenerator matrices (screen mesh, rolled foil), and working gases (air, helium, hydrogen).

Laland contends evolutionary biology is not being overturned but broadened by the extended evolutionary synthesis (EES). Epigenetic inheritance demonstrates acquired traits can pass between generations; culture and social learning affect fitness and drive evolutionary change across animals and humans; developmental processes can bias variation and steer evolution, not just selection. The EES treats inheritance as multi-layered (genes, epigenetic marks, culture, parental effects) and aims to generate new hypotheses, not spark a revolution. Kuhn/Popper debates aside, the field evolves through pluralism and revised research programs, while media hype exaggerates upheaval.

Echo Chess is a single-player, chess-inspired puzzle where capturing pieces reshapes the maze as you play. The author added Classic and Endless modes, with procedural level generation and a compoundFEN encoding for states with obstacles. To ensure solvable mazes, a data-driven predictor was built from 5.5k+ labeled levels, testing multiple models (Random Forest, Balanced RF, XGBoost, CNN) and using oversampling and data augmentation. Threshold-tuned ensembles yield high precision with few false positives. In production, Endless mode samples 50 candidates and uses majority voting to deliver solvable levels at ~99%+, while other ideas include NLP/LLM-based approaches.

HTTP headers carry metadata for requests and responses, guiding content type, caching, authentication, security, and how web apps and APIs behave. Understanding and manipulating headers helps optimize performance, reliability, and security. Common header groups include: Cache headers (cache-control, expires, last-modified, etag); Content headers (content-type, content-length, content-encoding, transfer-encoding); Security headers (content-security-policy, x-frame-options, x-xss-protection, x-content-type-options). They enable efficient API integrations and safer, faster web applications.

Lume is an open-source macOS VM runtime/framework for building AI agents, automating macOS tasks, and running CI/CD on Apple Silicon. It uses Apple’s Virtualization Framework to run macOS and Linux VMs at near-native speed via a single binary with a CLI and an HTTP API (lume serve). Features include native speed, paravirtualized graphics, sparse disks, Rosetta 2 support, automated golden images, and registry support. Use cases: cross-version macOS testing, automated setups, local CI, sandboxing risky code, and AI agent development via the Cua Computer SDK. Not for Intel Macs. MIT licensed.

Flux 2 klein-4B is a pure-C inference implementation for text-to-image generation, using the Flux.2-klein-4B model. The project provides a C library (libflux) with no external dependencies beyond the C standard library; optional BLAS or Apple Metal acceleration for speed. It supports text-to-image and image-to-image generation, with an integrated Qwen3-4B text encoder and memory-efficient operation (encoder released after encoding, peak ~16GB). The repository includes examples, API references, and build targets (make generic/blas/mps). Model files (~16GB) downloaded via HuggingFace. MIT licensed.

Argues that MySQL is not truly open source under Oracle, citing reduced development activity, closed processes, and numerous 2025 CVEs; contrasts this with MariaDB’s open, actively developed community and transparent issue tracking; warns that Oracle’s approach prioritizes closed services like Heatwave and poses security risks; recommends migrating to MariaDB as the easiest path, with PostgreSQL, Percona, or TiDB as alternatives, noting WordPress sites commonly run MariaDB.

Humans establish a ground presence on Chelicer 14d to harvest a unique crop tended by the Chelicer 'Farmers' (Species 11). When giant death-fleas attack, the crew fights back, but the corporate brain (the Concern) pushes to wipe out the fleas with hunter drones, prioritizing resource revenue over ecology. Biologist FenJuan hints at deep, interconnected genetics and life-cycle shifts the world is undergoing. The cull eliminates the fleas, but the Chelicer ecosystem begins to transform and then collapse—species metamorphose into others, then vanish. A mass extinction ends life on Chelicer; the last elevator takes the biologists away as dust remains.

Hotness = - (base + order × sign + age); posts sorted by increasing hotness. Base sums tag hotness_mods and a small boost for self-authored links; some tags are penalized. Order is logarithmic in score with a cap from non-submitter upvotes. Sign is -1, 0, or +1 by score. Age grows with time (created_at / hotness_window ~22h), so newer posts need more upvotes to stay visible. Mindful participation matters.

A$AP Rocky's Helicopter music video uses volumetric capture and Gaussian splatting radiance fields to render most performances as dynamic splats, enabling radical post-production freedom. Evercoast captured with 56 RGB-D cameras in LA; performers were suspended and shot stunts, yielding over 10 TB of raw data and roughly 30 minutes of final splatted footage (~1 TB of PLYs). The team used Houdini with GSOPs and OctaneRender, plus Blender for planning, enabling relighting and a 3D look. The footage is not AI-generated; all stunts were physically performed, continuing Rocky’s history with radiance-field tech.
