Small AI models, a few billion parameters, can run on low-power devices, enabling life-saving services where connectivity is scarce. Examples: RxScanner on smartphones in Africa for drug authentication; on-device disease detection in India; mosquito surveillance; Arduino-based ECGs in Brazil. Pruning and distillation adapt large models for edge use. Hardware advances and open-weight models (Gemma 4, Qwen 3.5) boost on-device AI. The World Bank and governments fund small-AI programs (e.g., Rwanda), but reliable power, supply chains, and education remain essential; large models are still needed to build these systems.

Poly/ML is a fast Standard ML implementation with a conservative language subset, a parallel garbage collector, and a thread library. It includes a rich Basis library and a foreign-function interface to load C/C++ libraries. It targets large projects such as Isabelle and HOL, supports i386 and ARM64 natively (with a bytecode interpreter on other architectures), and is available on GitHub under LGPL-2.1.

Daniel introduces the Acronym Fatigue Series (AFS) to explain why he’s wary of acronyms. He attributes this to cultural differences and pervasive marketing that uses in-group signaling. The four-part series will cover: Part 1 CAP/ACID; Part 2 DRY/KISS; Part 3 OLAP/OLTP vs ELT/ETL. He contrasts his humanities background with English-dominated CS, noting acronyms are rarer in humanities. He cautions that meme-like acronyms can overshadow ideas (SOLID cited). He mentions webmentions as his comment mechanism.

An individual documents sequencing their own genome five times at home using an Oxford Nanopore MinION, from cheek swabs to end-to-end data analysis. The piece outlines turning raw DNA into a genome-ready dataset and querying variants with tools such as VEP, ClinVar, gnomAD, PharmGKB, and Claude, then annotating and interpreting results with emphasis that findings are not diagnostic. It discusses equipment, consumables, and costs, plus a thorough DIY protocol, and foresees future affordable, AI-assisted genomic insight while cautioning against DIY gene edits.

Not everything should cost a token argues that routing every task through an LLM inflates costs and bloats context. It distinguishes probabilistic work (the agent) from deterministic work (the app). Let judgment and interpretation live with the agent; move scheduled tasks, data pulls, transforms, and API calls to the app layer; store structured data in a real database; keep unstructured context in notes. Vybe’s pattern merges reasoning and execution: deterministic plumbing runs behind the scenes, while the model handles only judgment. This separation cuts costs and preserves quality.

Ternlight provides a small, CPU-only embedding model that runs entirely in the browser with no API calls. The 7 MB engine (5 MB mini variant) embeds text in ~5 ms on CPU and ships as a single npm package (@ternlight/base or @ternlight/mini) with no model download. It enables client-side semantic search (embed and similar) and is demonstrated on React docs. MIT license; once loaded, assets are cached.

Outlines λFS, a finite-functional approach where relations are finite functions represented by a table of their support. Nontermination raises evaluation-order issues, illustrated by R, S, and test, where termination depends on evaluation order. Proposes three forward semantic directions for recursion in λFS: (1) left-to-right evaluation with a simple cost model; (2) nondeterministic evaluation order for declarative optimizations; (3) parallel-and to regain determinism, with implementation trade-offs. Also discusses recursion types and join behavior.

riddle is a diary app for the reMarkable Paper Pro that writes back in ink as you handwrite Tom Riddle’s diary. It runs on-device with an LLM backend: an OpenAI-compatible API or a local pi process, streaming replies as you write. It intercepts the vendor display to render instant ink, with two build modes—Windowed (AppLoad) and Takeover (instant ink). Install via a prebuilt bundle or build from source, requiring developer mode and AppLoad. Tested on reMarkable Paper Pro (OS 3.26–3.27), not affiliated with reMarkable. MIT license.

Martin Alderson argues that AI margins hinge on inference costs, not upfront training, since training is fixed while inference scales with demand. He reviews GLM 5.2 from Z.ai as a competitive open-weight rival to Opus and GPT, with about $4.40/MTok and easy migration, but it lacks vision and strong web search, hindering interactive use. Open-weight paradigms ease switching, while frontier labs rely on training amortized over expensive inference. Data privacy/on‑prem options exist, and costs should fall with optimization and hardware improvements. Part 2 will examine how a margin collapse reshapes winners and losers.

M/PC is a concatenative, postfix OS for Varvara inspired by OpenFirmware that manages files without a graphical browser. It uses stack-based postfix commands; files can store command sequences and tilde-prefixed lines include file content. The single-prompt interface supports keyboard-free navigation to folders and ROMs, and can boot as a BIOS ROM (uxnemu m_pc.rom orca.rom). On boot it draws a wallpaper ICN. Primitives cover file ops (dir, mov, now, run, icn, txt, len, put, get, cpy, era, ren) and stack/arithmetic/logical ops (pop, dup, ovr, swp, rot, add, sub, dec, hex, cat, cmp, and, ora, rsz, out, bye).

AI: The ROI Runway Could Be Long Outside the Tech Sector argues that profits from AI may take longer to materialize outside tech. While some firms can integrate AI quickly, many sectors—health care, banking and insurance, energy and utilities, defense and aerospace, manufacturing, transportation and logistics, construction and real estate, education, legal, and the public sector—face slow productivity gains due to process re-engineering and data governance. If token costs fall toward zero, AI revenue may be constrained, risking a repricing of valuations tied to future earnings. The key question is how long the ROI runway will be, and its implications for AI company valuations.
