Side-by-side or overlay PDF diff driven by one engine that reads each file into a structured model — text, vector geometry, images, form fields, annotations — and compares the models. Moves show as moves, edits show only where they happened, and any PDF type works without picking a mode.
Open a STEP / STP part and it measures itself — volume, thinnest wall, draft and undercut checks on load, plus hole detection with a BOM. Measure, section, export STL. Rust + WASM B-rep kernel, runs in your browser.
White, creamy, sour 'cereal yoghurt' drunk as a thirst-quencher. Made in 5 steps over 3.5 days – 13 days. The longest step, store and sell, takes 2–7 days (Sacca C 2012). Lactobacillus fermentum, L. plantarum and Candida krusei do most of the fermenting.

Variants
Akpan from kneaded sorghum flour (solid-state)Dry-milled flour kneaded with water and fermented 18-24 h as a dough, then slurried and cooked. Made by about 10% of producers.

Safety
Short shelf life: it keeps souring after it is made.
Survey of 145 producers and 607 consumers in Benin (Sacca et al. 2012). A WUR and UAC project has worked on a defined starter and a powder that can be made up with water.
