An update to Mond's MOND←TECH MAGAZINE piece on Rust micro-optimizations, titled 'How many options fit into a boolean?'. It explains why a Result<bool, bool> cannot be compressed beyond a byte due to needing a valid memory representation, discusses size_of and the turbofish syntax, and notes the challenges of embedding a PDF. The post also includes updates about the author's life—planning a move from Central Europe to Seattle to work in AI—and reflections on writing, enthusiasm for contributing to Paged Out!, and other tech musings.

David Noel Ng describes LLM Neuroanatomy: topping the HuggingFace Open LLM Leaderboard by duplicating middle transformer layers rather than training. He posits a functional anatomy for Transformers: early layers encode, late layers decode, middle layers form reusable circuits. He created a ‘brain scanner’ heatmap testing (i, j) configurations on 72B models, using two orthogonal probes (hard math and EQ) and a scoring method based on digit-distribution expectations. The optimal config (45,52) duplicates seven middle layers, boosting RYS-XLarge to #1 across five benchmarks with no weight updates. This suggests circuit-like middle layers and orthogonality to fine-tuning.

RFC 454545 proposes the Human Em Dash (HED), a Unicode character (U+10EAD) visually identical to the em dash but distinct, paired with a Human Attestation Mark (HAM, e.g., U+10EAC) to signal human authorship. Rendering remains the same; automated systems must not emit HAM. Conforming implementations verify evidence of hesitation (delays, backspaces, cursor movement). The concept, called Human Cognitive Proof-of-Work (HCPoW), aims to combat Dash Authenticity Collapse by differentiating human from AI-produced punctuation. Legacy em dashes remain valid; backward compatibility noted. Security, policy, and IANA considerations discussed; examples provided.

Debian has not decided on AI-generated contributions. A draft General Resolution by Lucas Nussbaum would allow AI-assisted contributions with safeguards: disclose substantial tool-generated content, label it [AI-Generated], and hold contributors accountable for merit, security, and licenses. Debate covered terminology (AI vs. specific LLMs) and uses (review, prototypes, production code). On onboarding, costs, ethics, and copyright, some urged tighter limits or bans. No vote; decisions remain case-by-case under current rules.

Tony Hoare (1934-2026), Turing Award winner and CS luminary known for quicksort, ALGOL, and Hoare logic, died at 92. Lance Fortnow shares personal reflections from Cambridge, including Hoare’s famous quicksort wager (paid when proved faster) and his understated professionalism, plus anecdotes about cinema outings during his Microsoft Cambridge days. The piece sketches Hoare’s varied background (classics/philosophy, Russian training) and his tempered views on future tech and government access, noting the online quotes attributed to him may be misattributed.

DD Photos is a photo‑album site generator and SvelteKit viewer. It converts exported photo folders into a fast static site: a Go photogen tool resizes JPEGs to WebP (grid 600px, full 1600px), extracts EXIF data, and writes JSON indexes (albums.json and per‑album index.json) plus a sitemap.xml. The frontend is prebuilt and served statically; no server code or database. Albums are defined in albums.yaml, with optional descriptions.txt and per‑photo captions in photogen.txt. Workflow: export photos, run photogen, build, and deploy to Apache or S3. Features include dark/light theme, lightbox, captions, permalinks, OpenGraph, keyboard navigation. AGPLv3.

Tutorial to run a minimal REST API for sending XMPP messages over HTTP with Prosody and the mod_post_msg module. Requires a Debian-like system and a domain; install prosody, prosody-modules, lua-unbound, liblua5.4-dev, certbot; install the post_msg module via prosodyctl; create a lean Prosody config with http/tls/post_msg enabled; obtain certificates with certbot; verify config and start Prosody. Send your first message by creating a user (e.g., [email protected]) and curling to https://your-domain:5281/msg/<recipient> with -u <sender>:<pass> and the message body; multiple users supported; JSON payloads available; can run behind a reverse proxy.

Intel’s Heracles chip accelerates fully homomorphic encryption (FHE) by up to 5,000× versus top Xeon CPUs. Built on a 3-nm FinFET process with 64 SIMD tile-pair cores (8×8 grid), it uses 48 GB of high-bandwidth memory (two 24-GB HBM chips) and a 9.6 TB/s fabric, plus 64 MB cache. Operating at 1.2 GHz, it completes FHE’s core transform in about 39 μs, far faster than CPUs (≈15 ms). Across seven operations, speedups range 1,074–5,547×. Competing startups pursue FHE accelerators; Intel aims for scale with upcoming commercialization, including potential photonic approaches.

The article argues Magit’s rebasing is best learned via its interactive log. By opening Magit (F3) and using lL you get a discoverable, hint-driven log to filter by author (-A), date (=u), show a graph (-s), limit to tests (-- tests), and view all branches (b). To rebase, switch to profiling-of-test-suite, then rebase onto optimise-company-name-generation using re (with elsewhere). An interactive rebase shows editable commits and keys like k, f, w, s. The $ command log reveals exact git commands, including --autostash by default, illustrating Magit’s transparency and educational value versus other UIs.

EVi is a hard fork of Vim v9.1.2073 (Jan 2026) designed to avoid AI taint while extending Vim’s foundations. It retains Vi compatibility and adds features such as multi-level undo, syntax highlighting, command history, online help, spell checking, filename completion, block operations, and a GUI. Distribution is from Codeberg. The README for version 10.0 covers installation, documentation, and licensing (charityware, GPL-compatible); contributions are welcome. The project continues Bram Moolenaar’s Vim legacy with no AI integration.

Practical Guide to Bare Metal C++ explains how to use modern C++ (C++11) for embedded bare‑metal development, focusing on soft real‑time systems without heavy RTOS. It argues why C++ can outperform C via templates and code reuse, but warns about overhead from exceptions, RTTI and the standard library. It outlines a Device–Driver–Component architecture and an EventLoop model to handle interrupts and non‑interrupt contexts, with templates for generic peripherals, custom allocators, and logging. It also documents embxx/embxx_on_rpi libraries and concrete peripheral examples (UART, Timer, GPIO, I2C, SPI), startup/linker considerations, and offline builds.
