pdfsandwich generates "sandwich" OCR pdf files, i.e. pdf files which contain only images (but no editable text) will be processed by optical character recognition (OCR) and the text will be added to each page invisibly "behind" the images. pdfsandwich is a command line tool which is supposed to be useful to OCR scanned books or journals. It is able to recognize the page layout even for multicolumn text. Essentially, pdfsandwich is a wrapper script which calls the following binaries: convert, unpaper, tesseract, gs, and hocr2pdf (if tesseract < 3.03). It is known to run on Unix systems and has been tested on Linux and MacOS X. It supports parallel processing on multiprocessor systems. In contrast to most competing sandwich programs, it performs preprocessing of the scanned images, such as de-skewing or removal of dark edges etc. For further information please read the manual: http://www.tobias-elze.de/pdfsandwich/index.html

Vouch
A community trust management system based on explicit vouches
Vouch is an open-source community trust management system that introduces an explicit vouching model to govern who is allowed to contribute to a project’s critical interactions, such as opening issues or submitting pull requests. Traditional open source has relied on implicit trust earned through effort, but the advent of AI-generated low-quality contributions has made maintainers seek more intentional vetting processes. With Vouch, existing trusted contributors explicitly “vouch” for new community members before they can participate in selected parts of the project, and they can also “denounce” users to block them should they act in bad faith. The system stores trust decisions in a simple flat file format that integrates easily with version control and can be parsed using standard tools, making the trust layer lightweight and transparent. -
