So you want to modify the text of a PDF by hand...

If you, like me, resent every dollar spent on commercial PDF tools, you might want to know how to change the text content of a PDF without having to pay for Adobe Acrobat or another PDF tool. I didn't see an obvious open-source tool that lets you dig into PDF internals, but I did discover a few useful facts about how PDFs are structured that I think may prove useful to others (or myself) in the future. They are recorded here. They are surely not universally applicable --
the PDF standard is truly Byzantine -- but they worked for my case.

A Markdown/Makefile/Vim Notetaking Solution

If you're anything like me, you have a hard time taking notes on your computer. I would prefer to type all my notes in Vim but when it comes to reading, I'd much rather see a PDF. Hence the need for a better note taking system. My requirements for the tool were as follows:

1. I should be able to store my Markdown in a different directory than the compiled output to help with tab completion.
2. I should be able to compile all of my Markdown notes into PDFs separately and only and only when sources have been updated.
3. I want to be able to preview what the PDF will look like while taking notes, without exiting Vim.

In the end, my solution contained a Makefile, a Python compilation script, and an additional command in my .vimrc file:

# Reference: https://www.exclamationlabs.com/blog/continuous-deployment-to-npm-using-gitlab-ci/

# GitLab uses docker in the background, so we need to specify the 
# image versions. This is useful because we're freely to use
# multiple node versions to work with it. They come from the docker
# repo.
# Uses NodeJS V 9.4.0
image: node:9.4.0

# And to cache them as well.

If you are getting this in gdb on macOS while trying to run a program:

Unable to find Mach task port for process-id 57573: (os/kern) failure (0x5).
 (please check gdb is codesigned - see taskgated(8))

1. Open Keychain Access
2. In menu, open Keychain Access > Certificate Assistant > Create a certificate
3. Give it a name (e.g. gdbc)
