Experimental Linux support for Fairphone 6's ultra-wide camera shows mainline Linux can drive the OV13B10 sensor via qcom-camss and libcamera. The author ported the milos camera capture path (TFE665, CSID665, CSIPHY v2.2.1) and added a milos device-tree node, clocks, and an OV13B10 probe on I2C. Fixes included correct lane numbering and a write-bus packer value (0x0) to avoid zero frames. With libcamera, basic RGB frames are produced and QR scanning works in GNOME/Camera. Limitations: autofocus missing, other sensors unsupported, binned modes broken, simplified power sequencing; upstreaming pending.

New DNA analysis of Medici remains provides strong evidence that Francesco I de’ Medici and his wife Bianca Cappello died of malaria in 1587. Researchers found two malaria parasite species—Plasmodium falciparum and P. malariae—in Francesco’s bones, and a malaria strain in Giovanni de’ Medici as well. The Yale–Pisa study, published in iScience, supports malaria as the likely cause and complicates but does not entirely rule out arsenic poisoning. Paleogenomics advances address a long-standing historical question but stops short of a definitive murder verdict.

Benjamin Breen recalls shelving books in the Library of Congress, reading random pages to stumble on compelling non-fiction, and how that filtered sampling shaped his thinking. He notes libraries are changing—open stacks shrinking and e-editions growing—and argues non-fiction remains a golden age. He built a free “Book Prize Index” (with Claude Code) to search the long tail of high-quality non-fiction by aggregating prize finalists and winners and applying semantic search to ~6,500 titles. The tool surfaces “books like” matches and visuals, prompting reflections on libraries, prizes, and writing quality.

Charles Choi describes turning a repetitive task—copying GitHub issues into Org mode for Emacs Agenda—into a malleable automation workflow. He built fj.el, a compact Emacs Lisp tool that uses the gh CLI to fetch issues, a Transient UI and vtable for display, and Pandoc/ox-gfm to translate between Markdown and Org. In ~400 lines, it automates: fetch issues, display in a UI, copy to Org, create issues, and open in a browser, all from Emacs. He argues malleable computing empowers users to compose tools rather than rely on siloed apps.

An exploration of OCaml and the Eio concurrency library by Matt Hall. After trying Real World OCaml and CS3110, he finds OCaml enjoyable, mixing functional/imperative styles, despite verbose syntax and slow error iteration. He experiments with Eio's deterministic, effects-based IO, including a simple RPC-like Dumb_rpc with a server and a client toy that uses fibers, streams, and promises to support concurrent calls to Echo and Capitalise. He notes the learning path, library choices (Jane Street Base), and that Go-like flows can trip him up. He plans to implement Raft and return with results; overall OCaml is fun but niche.

Safari Technology Preview 248 is available for macOS Golden Gate and Tahoe. It updates WebKit (patch range 315567–316817) with accessibility, CSS, JavaScript, media, rendering, SVG, and Web API fixes and improvements. Notable additions include CSS: forwarding missing color components for color space interpolation and a no-clamp option for progress(); JavaScript: BigInt Math support (BigInt.pow, BigInt.sqrt); and WebDriver support for the Digital Credentials API. The release also fixes numerous issues across VoiceOver, aria-labels, video playback, scroll snapping, form controls, SVGs, and Web Inspector.

An engineer describes a recruiter’s take‑home Python project that doubles as malware. The repo’s pre-commit hook calls a remote IP, detects the host OS, and silently downloads and runs a payload (tokenlinux.npl/tokenlinux.sh) in the background. It fetches a hidden parser and a package.json, installs Node.js, and executes code with obfuscated scripts. Variants include a VSCode folder that auto-runs commands. The attackers tailor payloads per victim via an id parameter, clone a public repo, and even scan for open SSH ports. Moral: always inspect hidden dirs before running code.

The author reviews the NVIDIA DGX Spark as a quiet, power-efficient general-purpose PC (ARM CPU, RTX-like GPU, 128 GB RAM, 4 TB SSD) running Ubuntu-based DGX OS. It handles light gaming (Crysis Remastered via Proton on arm64) and desktop tasks well, though gaming isn’t its raison d’être. Local LLM inference has improved, with NVFP4, KV-cache, and DFlash boosting speeds; ~30-40 tokens/s per model, ~100 tok/s with four agents, and ~170 tok/s on larger 35B models. Some software (Darktable, Rhino 3D, Need for Speed, StarCraft II) requires tinkering. He also built a custom shelf/dock. Overall, a capable daily driver.

Retro-tech fan finds a 1978 Panasonic RQ-2106 shoebox cassette recorder for under €10. It still works, aside from a fragile fast-forward cog he fixes with glue. He tests with a Five Finger Death Punch cassette and then attempts to record actual music. To capture from his Mac, he converts the 5‑pin DIN output via an adapter and uses a Boss Katana Gen 3 guitar amp as an audio interface, boosting the signal. The result is listenable but the sound remains cassette‑quality; cassettes are easy to write to and look cool.

Hashimoto argues SIMD is approachable and broadly useful, not just niche optimization. He outlines a universal five-step pattern: broadcast a constant, loop over input in vector-width chunks, perform the SIMD operation across lanes, reduce or store the result, then finish with a scalar tail. He explains how to reason about lanes and vector width, why compilers often auto-vectorize poorly, and why explicit SIMD is preferred for predictability. A Ghostty example yields 4×–16× speedups (ARM to AVX-512), with ~5× real-world gains.

Castillo tests whether AI labs are pelicanmaxxing by re-running Simon Willison’s SVG prompt across 1,008 images from seven frontier models (GPT-5.6 Terra, Claude Sonnet 5, Gemini 3.5 Flash, Grok 4.5, Qwen3.7-Max, GLM-5.2, DeepSeek V4 Pro). Using a three-stage pipeline—rendering, a GPT-5.6 Luna judge, and Gemini 3.1 Flash‑Lite feature extraction—he analyzes whether pelicans on bicycles are boosted beyond other animal/vehicle combos. The results: pelicans and bicycles aren’t drawn better than average, and the pelican-bicycle cell shows no lab boost after accounting for difficulty. Direction bias and memorization trends exist but don’t indicate pelicanmaxxing. Conclusion: little evidence labs optimize this benchmark.

NVLink on consumer GPUs is largely obsolete after Nvidia dropped support post-RTX 3090; bridges cost $200–$400. In tests with two RTX 3090s on Ubuntu, layer-split model inference was unchanged, tensor-parallel inference gained ~30% in prompt processing (token generation unchanged), DDP training unchanged, and FSDP training nearly tripled. However, results hinge on P2P vs SHM: enabling P2P via a patch narrows the NVLink edge, giving near-P2P speeds and roughly 90% of NVLink for FSDP. Verdict: NVLink makes sense mainly on consumer rigs with limited PCIe lanes for FSDP or tensor-parallel workloads; otherwise, buy a workstation/server with full x16 lanes.

AI infrastructure debt increasingly collateralizes tens of billions of dollars with GPUs rather than borrowers’ balance sheets. The collateral’s value hinges on operational state and the tacit knowledge of the borrower’s ops team, which lenders cannot access, making risk hard to price. GPU-backed SPVs (e.g., xAI Colossus, CoreWeave) command large premiums above benchmarks because there is no established price discovery, residual value curves, or futures market. Real risks include silent data corruption, cascading failures, and handoff issues if a lender steps in. As markets mature, hedges and markets for used GPUs may reduce the cost of capital.

Gigatoken is a Rust-based tokenizer for language-model tokenization at GB/s, claiming up to ~1000x faster than HuggingFace tokenizers via SIMD and cache optimizations, with compatibility modes for HF Tokenizers and Tiktoken. It offers a Python API (pip install gigatoken) and a fastest API that reads data directly, enabling near drop-in replacements for popular tokenizers. Benchmarks show large throughput gains across CPUs and models (GPT-2, Qwen, Llama, etc.). Includes usage examples, benchmarking guidance, and known issues (Python ABI3, Windows, SentencePiece).

SWING NYC is a voxel Manhattan web-swing game. Controls: left mouse to swing; hold to build momentum, release at the arc’s top. W/A/S/D steer on ground and in air. Space to jump; tap for a jump, hold and release for a super jump. In air, Space performs an air dash toward the held direction (one per swing). DIVE to dive for speed (hold; Shift also triggers a dive to trade altitude for speed). R respawns on the rooftop. Drag the right side of the screen for camera. Click to swing.
