Alexa, build me an app

Building an Amazon Echo (Alexa) skill is extremely simple, if a bit cumbersome. If you're not familiar, the Echo is an always-on home automation unit with built-in support for things like playing streaming music, getting weather information, and even turning on your wifi-connected lights. Amazon also allows developers to extend the Echo's functionality with custom "skills". These skills get the benefit of Amazon's full speech analysis engine and works through a simple JSON web API. In this talk we'll cover how we can use Node.js to write a simple skill and what else we need to do to get up and running. You'll learn how to test your new skill with a real voice interface and the basics of the cumbersome setup process on Amazon's developer portal along with some best practices. You don't need to own an Echo to write a skill... although they sure are fun to play with!

JavaScript file size validation for HTML 5, using jQuery Tools validation and Parsley validation. (Additionally, extended modernizer for HTML5 File API.). The 'data-filemaxsize' attribute should be set in megabytes.

Business models based on the compiled list at http://news.ycombinator.com/item?id=4924647. I find the link very hard to browse, so I made a simple version in Markdown instead.

It's a résumé, as a readable and compilable C source file. Since Hacker News got here, this has been updated to be most of my actual résumé. This isn't a serious document, just a concept to annoy people who talk about recruiting and the formats they accept résumés in. It's also relatively representative of my coding style.

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
