Preface

Together with HellMood we won this year's (2016) JS1K competition and thought this might be a good opportunity to write about the development process and my motivation behind it. If you're already familiar with JS1K, feel free to skip the next two paragraphs.

Reference: RFC 2616 - HTTP Status Code Definitions

General

400 BAD REQUEST: The request was invalid or cannot be otherwise served. An accompanying error message will explain further. For security reasons, requests without authentication are considered invalid and will yield this response.
401 UNAUTHORIZED: The authentication credentials are missing, or if supplied are not valid or not sufficient to access the resource.
403 FORBIDDEN: The request has been refused. See the accompanying message for the specific reason (most likely for exceeding rate limit).
404 NOT FOUND: The URI requested is invalid or the resource requested does not exists.
406 NOT ACCEPTABLE: The request specified an invalid format.

RFC 1345 Compose Keys

The notion of Compose keys are brilliant. I really like the notion of pressing a key, typing a sequence of characters, and out pops a pretty Unicode character. However, the default sequences in X are immensely silly, and in any case, there's already an RFC for this.

RFC 1345 exists to specify a simple way of entering Unicode characters, and it's a crying shame that Compose keys don't use it,
