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.
LaunchOpen 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.

Fish and seafood from Russia
Among the Itelmen of Kamchatka, fish was kept in two ways, as dried yukola and as fish seasoned in pits (Shnirelman, as summarised on Wikipedia). At home the dogs were fed soup made from the fermented fish. No source opened in this round describes the method or gives any numbers, so the one step here is an outline only.
A short entry: the sources we found record only what is said here about Kamchatka pit-fermented fish itself. Its own sources do not record how it is made, so the steps and scenes below are those of Tepa (stinkheads), the closest documented fish and seafood ferment, shown as a guide to the method, not as a record of Kamchatka pit-fermented fish.

Among the Itelmen of Kamchatka, fish was kept in two ways, as dried yukola and as fish seasoned in pits (Shnirelman, as summarised on Wikipedia). At home the dogs were fed soup made from the fermented fish. No source opened in this round describes the method or gives any numbers, so the one step here is an outline only.
This page outlines a traditional practice; it is not a recipe to follow. No source we found tests this method for safety. The closest studied case is Alaskan pit-aged fish (see tepa), where fermented fish and other aquatic animals caused most foodborne botulism (CDC), and WHO lists fermented fish among the foods that have carried the toxin, which can kill. The toxin cannot be seen, smelled or tasted. CDC advises boiling home-fermented Alaska Native foods for 10 minutes before eating; that advice was not written for Kamchatka fish.
Every number is labelled with how it is known. How this atlas is made
Shnirelman, as summarised on Wikipedia, describes two Itelmen ways of keeping fish, yukola (dried fish) and fish seasoned in pits; at home the dogs were fed soup made from the fermented fish.
