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.
Clear rice wine, about 15 % alcohol after dilution; undiluted genshu is 17–20 %. Made in 13 steps over 7.6 months – 14 months. The longest step, mature, takes 6–12 months (Japan Sake and Shochu Makers Association and…) and runs at 10–15 °C (Japan Sake and Shochu Makers Association and…). Aspergillus oryzae and Saccharomyces cerevisiae sake strains do most of the fermenting.

Sake probably dates from the Nara period (710–794). In the Muromachi period Shōryaku-ji (Nara) used polished rice, three-stage brewing, bodaimoto and pasteurisation. Winter-only brewing was ordered in 1673. The national brewing institute (now NRIB) was founded in 1904, Brewing Society (Kyokai) yeasts have been sent out since 1906, yamahai-moto and sokujo-moto were invented in 1909, and the first national new-sake competition ran in 1911.
