After reading through the first section and exercises, and having zero interest in game theory, I must say this is really well done. All mathematical subjects should aim towards teaching clearly step by step like this, with a ton of well formed and worked out excercoses, instead of just drowning the reading in notation.

My whole PDF library is exactly this.

As a sidenote, isn't this pretty much why the PDF remains so popular as a format, at least in science - you get a typeset copy with no worry you'll ever lose access or not be able to read it... you just need that spare hour or two... :)

Yesterday, this occurred to me. I quickly forget which pdf I have downloaded. I was searching for an application who is basically a to do list for pdf (a "pocket" for pdf).

Does anyone have an application like that?

Mendeley or Zotero's tagging might work well for this. Both are more commonly used for organizing bibliographies in science, but should work here as well.

I store PDFs in Google Drive by quarter (e.g. ~/content/2015Q4/), and generally try to add a few relevant terms in the title. The only thing that bothers me is that I have to go through and specifically mark the files as available offline.

That actually sounds like a really good idea. Right now the only thing I for this is keeping a folder on my desktop titled "Reading Queue", and I drop symlinks in there to docs that I want to read sooner than later.

I upload to slack or evernote under different categories.

Well, there are at least 40, if not 500 years ahead of me.

That's like every text I own... FeelsBadMan
