# http://askubuntu.com/questions/27097/how-to-print-a-regular-file-to-pdf-from-command-line
# Dependencies: pdftk, tesseract, imagemagick, enscript, ps2pdf
# Would be nice to use hocr2pdf instead so that the text lines up with the PDF image.

Unfollow all on Facebook

Facebook: Unfollow people and pages

See comments section for more up-to-date versions of the script. The original script is from 2014 and will not work as is.

  1. Open news feed preferences on your Facebook menu (browser)
  2. Click people or pages
  3. Scroll down (or click see more) until your full list is loaded
  4. Run the script in your browser console

Facebook will block this feature for you while you use it, depending on how much entities you try to unfollow. It automatically unblocks in a couple of hours and you will be able to continue.

Orthodox C++

Orthodox C++

What is Orthodox C++?

Orthodox C++ (sometimes referred as C+) is minimal subset of C++ that improves C, but avoids all unnecessary things from so called Modern C++. It's exactly opposite of what Modern C++ suppose to be.

Why not Modern C++?

How to generate and apply patches with git?

It sometimes happen you need change code on a machine from which you cannot push to the repo. You’re ready to copy/paste what diff outputs to your local working copy.

You think there must be a better way to proceed and you’re right. It’s a simple 2 steps process:

1. Generate the patch:

git diff &gt; some-changes.patch
