Since this is on Hacker News and reddit...

• No, I don't distribute my résumé like this. A friend of mine made a joke about me being the kind of person who would do this, so I did (the link on that page was added later). My actual résumé is a good bit crazier.
• I apologize for the use of _t in my types. I spend a lot of time at a level where I can do that; "reserved for system libraries? I am the system libraries".
• Since people kept complaining, I've fixed the assignments of string literals to non-const char *s.
• My use of type * name, however, is entirely intentional.
• If you're using an older compiler, you might have trouble with the anonymous unions and the designated initializers - I think gcc 4.4 requires some extra braces to get them working together. Anything reasonably recent should work fine. Clang and gcc (newer than 4.4, at le

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.

12 Years of ToaruOS

This is a repost and update to an imgur album with screenshots of ToaruOS throughout its development, as imgur is no longer a viable platform for maintaining this collection.

Early Development

My first commit in the ToaruOS repository, ecd4fe2bc170b01ad700ff76c16da96993805355, was made on January 15th, 2011. This date has become ToaruOS's "birthday". It would be another six years and two weeks before ToaruOS's first real release, 1.0.
