how to install Okular viewer on macOS Big Sur, using M1/Apple Silicon/arm64
  1. Install homebrew from https://brew.sh/ (follow the instructions there)
  2. tap the https://invent.kde.org/packaging/homebrew-kde/ repo, brew tap kde-mac/kde https://invent.kde.org/packaging/homebrew-kde.git
  3. brew edit okular, workaround now is to comment out or delete the line depends_on "chmlib" (won't compile on macos arm64 for now as of 2021-08-18), then save (if using vim you need to first press i to insert/type, when saving then <esc> then :wq then <enter>.
  4. brew install okular, wait for stuff to compile and/or install
  5. It may ask for keychain credentials (to sign the binaries? because of mac arm64 security policy https://eclecticlight.co/2021/01/26/when-you-dont-have-permission-to-run-an-app-on-an-m1-mac/)
  6. $(brew --repo kde-mac/kde)/tools/do-caveats.sh
  7. Now okular is in your $HOME/Applications/KDE folder, and will show up in Launchpad! You can view pdf, djvu, etc documents.

Programmer's Links: Basics

Floating Point Numbers
They are very useful but often used in situations where they simply don’t suit the solution the programmer is attempting to write. The following links should provide some background and info on where they are not so useful, what the pitfalls are and sometimes even how to avoid them.
