How to compress PDF using ghostscript

As a developer, it bothers me when someone sends me a large pdf file compared to the number of pages. Recently, I recieved a 12MB scanned document for just one letter-sized page... so I got to googlin, like I usually do, and found ghostscript!

to learn more abot ghostscript (gs): https://www.ghostscript.com/

What we are interested in, is the gs command line tool, which provides many options for manipulating PDF, but we are interested in compressign those large PDF's into small yet legible documents.

How to remote pair, over SSH?

If you are capable of direct access

Just connect; Done;

But… I’m behind NAT, and Firewalls and everything!

I thought so… The internet is not that easy of a place huh?! They told everybody would be connected, and promised again with IPv6, but I’m disgressing.

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

Referências para aprender Python

Me perguntaram dicas sobre como aprender Python para quem nunca programou antes. Não é a minha especialidade, mas graças aos meus amigos no Twitter e no Facebook, consegui juntar uma lista de referências que espero ser útil.

Se alguém tiver mais referências, por favor, deixem comentários ou me mande uma mensagem em @rafaelrosafu.

Technology

Setup Mac OS X

I've done the same process every couple years since 2013 (Mountain Lion, Mavericks, High Sierra, Catalina) and I updated the Gist each time I've done it.

I kinda regret for not using something like Boxen (or anything similar) to automate the process, but TBH I only actually needed to these steps once every couple years...

	https://apple.stackexchange.com/questions/332769/macos-disable-popup-showing-accented-characters-when-holding-down-a-key

	# In macOS, when a key is held down while entering text, a popup is shown which lets one choose between various accented
	# forms of the character. To disable this execute the following command-line in the Terminal.app:

	defaults write -g ApplePressAndHoldEnabled -bool false

	# Now, you'll need to log-out and log back in. This should disable the display of the popup and character typed should
	# start repeating when the key is held down.

	Remove osxfuse if installed via homebrew:
	> brew uninstall osxfuse

	Install osxfuse binary and choose to install the MacFUSE compatibility layer:
	http://sourceforge.net/projects/osxfuse/files/latest/download?source=files

	Reboot (optional but recommended by osxfuse)

	Install ntfs-3g via homebrew:
	> brew update && brew install ntfs-3g
