A simple Ghostscript command to merge two PDFs in a single file is shown below:

gs -dNOPAUSE -sDEVICE=pdfwrite -sOUTPUTFILE=combine.pdf -dBATCH 1.pdf 2.pdf

Install Ghostscript:

Type the command sudo apt-get install ghostscript to download and install the ghostscript package and all of the packages it depends on.

Guidelines for contribution

This document described guidelines for contributions for projects led by members of the [Poisot lab of computational ecology][pl], Université de Montréal. It should be followed by lab members (at all times), as well as people with suggested added features, or willing to contribute enhancement or bug fixes.

Authorship

Any contribution to the code of a software grants authorship on the next paper

Starting at the beginning:

Let's just assume you're using an Ubuntu-ish distro of Linux. In some ways that makes this a little more complicated, but on the other hand, it lets me assume you have experience with other package managers. So the big thing here is that conda is it's own little scientific apt-get (python packages, GIS tools, R + R packages, gcc, etc) that goes off and builds sandboxes contained in individual rooms. Then there's pip. Pip is specifically for python packages only and in my opinion, should only be used when the conda package isn't available.

Back to conda: conda is a package manager that depends on python, but is not per se an installation of python. So:

Don't use VPN services.

No, seriously, don't. You're probably reading this because you've asked what VPN service to use, and this is the answer.

Note: The content in this post does not apply to using VPN for their intended purpose; that is, as a virtual private (internal) network. It only applies to using it as a glorified proxy, which is what every third-party "VPN provider" does.

There's also this article about VPN services, which is honestly better written (and has more cat pictures!) than my article.
