+% General Architecture of this "Blogging" System
+
+The main idea behind this system is that my site is supposed to consist of
+*posts* which are organized into *lists of posts*. This mapping is not assumed
+to be injective, i.e. a post may be a member of many lists. In fact, this is how
+the list [All Posts](/lists/zz_all.html) is made: every post is supposed to be
+linked into it.
+
+To keep order in this mess of data, I have decided to map it into the file
+system. I have a folder `posts` which contains all posts and a folder `lists`
+with all the lists. Every list is a folder with symbolic links to posts:
+
+    blog
+    ├── lists
+    │   ├── all
+    │   │   ├── 001 -> ../../posts/hello-world.md
+    │   │   └── title
+    │   ├── blog
+    │   │   └── title
+    └── posts
+        └── hello-world.md
+
+As you can see, I have added a special file to each list folder named `title`
+which contains the title of the list (as you might have guessed).
+
+Posts are written as [Markdown](http://en.wikipedia.org/wiki/Markdown) files and
+converted to HTML with [Pandoc](http://en.wikipedia.org/wiki/Pandoc). Pandoc
+handles this conversion almost perfectly, but I had one small issue with
+it. Namely, I want to be able to write mathematics and hence translate
+TeX--snippets into something that your browser can display.
+
+Pandoc has several builtin methods to do this, but most of them either rely on a
+specialised TeX--parser or JavaScript. Both were deemed too ugly to use. So I
+wrote a filter around Pandoc to extract TeX-snippets and compile them with my
+regular LaTeX distribution into SVG. This seems to work quite nicely.
+
+The next issue was keeping this mess of posts and lists and Markdown files under
+control. Traditionally, I would have used a Makefile for that but I wanted
+something a little nicer this time. I turned to an old idea of
+[Dan Bernstein's](http://cr.yp.to/djb.html):
+[Redo](http://cr.yp.to/redo.html). There are several implementations of Redo out
+there; eventually I plan to write my own, just as practice. For now, I use a
+very minimal implementation in shell script from
+<https://github.com/apenwarr/redo>.
+
+More on how exactly the conversion from Markdown to HTML and all the associated
+ecosystem works will appear in a later post.
