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.

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.

Alcoholic drinks from Kilimanjaro Region, northeastern Tanzania
Mbege is the banana and finger-millet beer of the Chagga people on the slopes of Kilimanjaro. Ripe bananas are cooked into a porridge called nyalu and left to ferment, often with msesewe bark, while sprouted finger millet is cooked into a sweet porridge called mso. The two are mixed, and within about six hours the mix has become a mildly alcoholic, sour beer.
A short entry: the sources we found record only what is said here about Mbege itself.
| Ripe bananas | Cooked into the fermented porridge nyalu, which supplies the yeasts[kubo2016] |
| Finger millet, germinated | Cooked into the sweet porridge mso, which supplies the fermentable sugar[kubo2016] |
| Msesewe bark (Rauvolfia caffra stem bark) | Added to the nyalu; it speeds up its fermentation[kubo2016] |
| Starter | the fermented banana porridge (nyalu) is the source of yeasts |
Total time across the recorded steps: 6 h
What changes: Ripe bananas cook down into a thick porridge
Output: banana porridge.

Mbege is the banana and finger-millet beer of the Chagga people on the slopes of Kilimanjaro. Ripe bananas are cooked into a porridge called nyalu and left to ferment, often with msesewe bark, while sprouted finger millet is cooked into a sweet porridge called mso. The two are mixed, and within about six hours the mix has become a mildly alcoholic, sour beer. Made in 6 steps over 6 h. The longest step, mix nyalu and mso and ferment, takes 6 h (Kubo R 2016). Saccharomyces cerevisiae and Lactobacilli do most of the fermenting.

Mbege takes its yeast and its sugar from two separate porridges, a fermented banana porridge and a sweet sprouted-millet porridge, and mixes them only at the end. Orubisi, the Haya banana beer of northwestern Tanzania, is made from bananas and sorghum and is thinner.
Mbege keeps fermenting after it is made, so it is drunk within one or two days.
Every number is labelled with how it is known. How this atlas is made
Kubo and Kilasara (2016) call mbege the most popular indigenous alcoholic beverage in northeastern Tanzania, important to the economy of the region. Temba and colleagues (2025) call it the Chagga tribe's heritage beer.
