#+TITLE: Nebula: a remote filesystem idea

* Introduction

  I need a project to play around with the practicals of Racket. To

  me, practical uses are why I choose a given programming language

  mostly, and in this case, what I want to do intersects my systems

  and networking background. This idea is inspired by a talk from Joe

  Armstrong, from some previous ideas I've hacked on, and from talking

  on the tyrfingr IRC channel.

  The basic idea is a file storage system, available via a network

  connection. Files are identified by a SHA256 hash, preferably with

  some metadata associated (such as creation time). A file is

  immutable; once entered, it doesn't change.

* Basic idea

  The user can upload a stream of bytes (the file); the server will

  perform a SHA256 hash of the file and return this to the user. The

  file will be stored on disk in a file// directory.

  For example, the file containing

 

#+BEGIN_EXAMPLE

Hello, world.

#+END_EXAMPLE

  would be stored in

#+BEGIN_EXAMPLE

files/23eb/efdbe49a24e4bb9e243f649b3606c9241871a02d6122831d3cb7b2d6760~

#+END_EXAMPLE

  Some metadata might be entered in

#+BEGIN_EXAMPLE

meta/23eb/7efdbe49a24e4bb9e243f649b3606c9241871a02d6122831d3cb7b2d6760

#+END_EXAMPLE

* API

  This could be accomplished via either a TCP interface (using binary

  commands) or a REST API.

* Extending

  + ACL

  + Encryption

  + File lineage (i.e. what's the parent's hash, allows pruning the tree)

  + Is there a way to work garbage collection into this?
