In Praise of Observational Evidence

The essay argues that while randomized controlled trials (RCTs) are the medical gold standard, observational evidence can rival them when analyzed with modern causal methods. It traces the history of controlled trials from ancient to modern, explains biases and ethical limits of RCTs in public health, and advocates target trial emulation, inverse probability weighting, and double machine learning to adjust for confounding. With large datasets like PMA and VA Million Veterans Program, observational data can inform policy and practice, sometimes more cheaply and quickly than RCTs.

Microsoft Can Track Users via a Windows Device ID

PCMag reports that the FBI used a Microsoft 'Global Device ID' (GDID) to link a 19-year-old hacker, Peter Stokes, to alleged hacks, highlighting potential Windows-level surveillance. The GDID is a persistent, device-wide identifier that can be tied to third-party services and timing, potentially tracking a user's online activity without cookies. It can be reset by users, but is hard to manage; it remains after OS updates and reinstalling Windows can yield a new GDID. Privacy experts warn of abuse and note it may not be unique to Microsoft; experts suggest privacy measures and alternatives like Linux or proxies.

Dolosse – a South African invention used over the world

Dolosse are large South African–made concrete blocks used worldwide to protect coasts and breakwaters by dissipating wave energy while letting water flow through. In Port Elizabeth’s Coega harbour, about 30,000 dolosse (≈30 tons each) form the upper layer of a 2.5 km breakwater; blocks can weigh up to 80 tons. They can be placed randomly or neatly stacked. The invention arose from South African Railway & Harbour Services workers, who received no payment or patent, with inspirations linked to knucklebones or similar games.

Tiny-C Reference Manual Excerpt

Tiny-c is a small, portable language and toolchain inspired by BASIC and C. It provides a structured environment: a language, standard library, and a program preparation system, letting you write, edit, save, and reload programs offline. It is OS-independent and can interface with your system's I/O and even call machine-language subroutines. It supports if-then-else, while loops, functions, global and local variables, pointers and arrays, with an emphasis on readability via compound statements. The sample guess-the-number walk-through covers modular design and local/global scope.

I created a free tool that pairs your Nasic and past performance to win contract

FedFinder is a private federal-contract intelligence platform offering federal, state/local, and commercial coverage. It surfaces pre‑RFP forecasts (sources-sought, industry days, appropriations) by aggregating SAM.gov, USAspending, and other public sources, with fit scoring and an AI operator to suggest bids and assess competition. It links to contracting officers and program leads, grounding answers in public sources. Not a government site. Plans include a 14‑day trial (no card) and a 30‑day money-back guarantee; add‑ons exist; pricing per organization.

Strata – An app that talks me out of dying outdoors

Strata is an iOS backcountry planning app that reads avalanche bulletins, slope angle, aspect, and live weather to deliver one plain-English verdict on a route—go, watch, or avoid. It pairs smart route discovery with a multi-day planner, live crew positions, SOS sharing, and off-grid operation with offline maps and no ads. A 9-tile conditions ribbon shows current safety signals at a glance, while Claude-based analysis justifies the verdict. Pro unlocks snap-to-trail routing, offline map packs, unlimited saved routes, and trip reports. Privacy: location used for mapping and live sharing; data processed by Claude; no ads or cookies.

Small AI Models Gain Traction In places with unreliable networks

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 – A Standard ML Implementation

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.

How to sequence your own DNA at home

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.
