• batdoc - cat for Office documents and PDFs - LinuxLinks

  .pptx extracts text from all shapes on each slide. Font size is used to infer heading levels. Hyperlinks on text runs are resolved and rendered as markdown links. Multi-slide decks get ## Slide N headings.

  .pdf extracts text from text-based PDFs using pdf-extract. Multi-page documents get ## Page N headings in markdown mode. Scanned/image-only PDFs that contain no extractable text get a clean error message. Malformed PDFs that would crash the underlying library are caught and reported as errors rather than panics.

  This is free and open source software.

• Codon - extensible Python compiler - LinuxLinks

  Codon is a high-performance Python implementation that compiles to native machine code without any runtime overhead. Typical speedups over vanilla Python are on the order of 10-100x or more, on a single thread. Codon’s performance is typically on par with (and sometimes better than) that of C/C++.

  Unlike Python, Codon supports native multithreading, which can lead to speedups many times higher still.
