True redaction removes the text and images from the file — not a black box on top. Plus real in-place text editing, fill + sign, reorder pages, and OCR.
LaunchEdit text in place, sign, redact, fill forms, and reorganize PDF files in your browser — all on your device. No upload, no subscription.
Drop two versions of a contract or drawing set. Moved notes read as moves, changed values light up digit by digit, and hidden text is named.
LaunchSide-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.
Drop a Gerber ZIP, an ODB++ .tgz or an IPC-2581 .xml and inspect every layer — compare revisions, snap-to-pad measure, run DRC and preview the board in 3D.
LaunchOpen Gerber, Excellon, ODB++ and IPC-2581 PCB files. Inspect layers, measure traces, run DRC, export to PNG / SVG / DXF.
Open a .step / .stp part and it measures itself: volume, thinnest wall, draft and undercuts on load, and a hole list with a BOM in one click. Measure, section, export STL.

Alcoholic drinks from Central Highlands
Rượu cần is a rice wine of Vietnam's upland peoples that is not distilled. Cooked rice or maize is mixed with rice husk and a leaf starter (men lá), packed into an earthenware jar and sealed for a month or more. At a gathering, water is poured into the jar and people drink in turn through long bamboo tubes.
A short entry: the sources we found record only what is said here about Rượu cần itself.
| Rice or freshly pounded maize | Cooked until just done, then cooled[hue2024][vnn2026] |
| Rice husk | Mixed into the cooked grain[hue2024] |
| Men lá (leaf starter cake), crushed to powder | Each people uses its own plants, for example Đòng and Me kà zút among the K'Ho, and galangal with forest leaves and roots among the M'Nông[hue2024][vnn2026] |
| Spring water or cooled boiled water | Poured into the jar only when the wine is served[vnn2026] |
| Starter | koji/qu/mold-starter (men lá, a leaf starter cake) |
Total time across the recorded steps: 2.1 months
What changes: Rice and pounded forest plants are rolled into balls and dried over the fire
Glutinous rice is soaked for two nights and pounded before mixing. The M'Nông add dried galangal and rice husk and dry the cakes over the fire; a good cake is light and porous. Output: dry starter cakes.

Rượu cần is a rice wine of Vietnam's upland peoples that is not distilled. Cooked rice or maize is mixed with rice husk and a leaf starter (men lá), packed into an earthenware jar and sealed for a month or more. At a gathering, water is poured into the jar and people drink in turn through long bamboo tubes. Made in 6 steps over 2.1 months. The longest step, make the leaf starter (men lá), takes 33 days (Nguyễn Văn Huế 2024). Yeasts and Moulds do most of the fermenting.

The same leaf-starter mash, when distilled, gives a clear rice spirit; left undistilled in its jar it is rượu cần. The mash stays in the jar and water is added only when it is served, so the wine is drunk on the spot through tubes and only the liquid is taken.
No safety limits specific to rượu cần were found. As a home ferment, its alcohol and hygiene may vary from jar to jar.
Every number is labelled with how it is known. How this atlas is made
Rượu cần is made for festivals and rituals, and the order of drinking follows age and custom.
