Making a PDF + Bootable ISO Hybrid Polyglot

If you've not seen my résumé, that is what this post is about, and you should probably look at it first to get an idea of what's happening.

A Tale of Two Files

PDF and ISO9660 are two very different file formats. PDF is actually a surprisingly human-readable (but, sadly, not very human-writable) plain-text format, technically descended from PostScript. PDF is not very forgiving on changes, as it stores tables of offsets to various elements, so it is very difficult to insert or remove content manually without going through a robust PDF manipulation library.

ISO9660 is a disk filesystem, meant to be written once and read many times on many different kinds of hardware. As it is sector-based, it expects data structures to be at particular absolute offsets.

The introduction to Reactive Programming you've been missing

(by @andrestaltz)

So you're curious in learning this new thing called Reactive Programming, particularly its variant comprising of Rx, Bacon.js, RAC, and others.

Learning it is hard, even harder by the lack of good material. When I started, I tried looking for tutorials. I found only a handful of practical guides, but they just scratched the surface and never tackled the challenge of building the whole architecture around it. Library documentations often don't help when you're trying to understand some function. I mean, honestly, look at this:

Rx.Observable.prototype.flatMapLatest(selector, [thisArg])

Projects each element of an observable sequence into a new sequence of observable sequences by incorporating the element's index and then transforms an observable sequence of observable sequences into an observable sequence producing values only from the most recent observable sequence.
