Diffing contents of docker containers

Recently I worked on a project where a large refactor had taken place but I wanted to ensure that there was no changes to the built output of the docker container. So while the diff in Github was quite large with many files moved around the output should remain almost identical aside from a few extra files removed.

Export PDFs to PNGs

Ever want to convert a Google Slides presentation to images without having to save each one manually?

  1. Export from Google Slides to PDF. File > Download > PDF This will let us download all the images at once.
  2. Using the imagemagickBig nix package or installing with instructions from here you can then run the following command in the CLI:

convert -density 300 -quality 100 my-download.{pdf,png}

This will then convert the PDF to a series of images at 300 DPI.

fish shell script for quick access: pdf-to-png ./my-pdf-file.pdf
