This can reduce files to ~15% of their size (2.3M to 345K, in one case) with no obvious degradation of quality.

ghostscript -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dPDFSETTINGS=/printer -dNOPAUSE -dQUIET -dBATCH -sOutputFile=output.pdf input.pdf

Other options for PDFSETTINGS:

/screen selects low-resolution output similar to the Acrobat Distiller "Screen Optimized" setting.
/ebook selects medium-resolution output similar to the Acrobat Distiller "eBook" setting.
/printer selects output similar to the Acrobat Distiller "Print Optimized" setting.
/prepress selects output similar to Acrobat Distiller "Prepress Optimized" setting.

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

Deploying a subfolder to GitHub Pages

Sometimes you want to have a subdirectory on the master branch be the root directory of a repository’s gh-pages branch. This is useful for things like sites developed with Yeoman, or if you have a Jekyll site contained in the master branch alongside the rest of your code.

For the sake of this example, let’s pretend the subfolder containing your site is named dist.

Step 1

Remove the dist directory from the project’s .gitignore file (it’s ignored by default by Yeoman).

	;; evil-emacs-state is annoying, the following function and hook automatically
	;; switch back to evil-normal-state whenever the evil-emacs-state is entered.
	;; It allows a more consistent navigation experience among all mode maps.
	;; To enter special commands of custom mode maps, just enter the insert mode :-)
	(defun evil-emacs-state-2-evil-normal-state ()
	(evil-normal-state)
	(remove-hook 'post-command-hook 'evil-emacs-state-2-evil-normal-state))
	(add-hook 'evil-emacs-state-entry-hook
	(lambda ()
	(add-hook 'post-command-hook 'evil-emacs-state-2-evil-normal-state)))
