An ideal blogging framework for me

What is this? I am trying out a blog.

 I have been wanting to put out a blog for myself and my family, yet I am looking for a blogging framework that are more amenable to systematic programming. Being a command-line and Linux addict, I would require the following from my ideal blogging enviroment:

1) text-based entries, somewhat like Wiki or ReST or Asciidoc.
2) easy programming API for interacting with the blog system in the "cloud"

In this way, I can also store a copy of my own blog in my own computer, under SCM control (such as git). Growing up in an era where internet was not existent, I do not take internet from granted. Especially I do not want to put out a material which I do not have a personal copy of in my own computer.

Also, the framework should include the opportunity to upload files (i.e. some audio, video, or photo files) and possibly other files (.tar archive, etc).
