+This Site's Tech Stack
+======================
+
+As some of my close friends can vouch, I am known for sometimes setting up and
+using seemingly bizarre tech stacks for my personal sites. As such I thought it
+would be interesting to go in and explain the stack I made for this one.
+
+The Major Players
+-----------------
+
+### Markdown
+
+This is a markdown file that gets rendered to HTML and sent to you via the lua
+discount library. As I couldn't get the vanilla version from LuaRocks to work,
+I use Debian's version.
+
+I like Markdown for thigns like this as it is not only simple, but easy for
+people to read, even if they don't know markdown or haven't worked with any
+other document system than Office or other wisywig document processors.
+
+### Lapis
+
+Lapis is the middleware between Lua and Nginx that allows me to write pages
+simply. Here is some of the code that powers this page:
+
+```
+-- controllers/blog.moon
+class Blog extends lapis.Application
+  ["blog.post": "/blog/:name"]: =>
+    @name = util.slugify @params.name
+    @doc = oleg.cache "blogposts", @name, ->
+      local data
+      with io.open "blog/#{@name}.markdown", "r"
+        data = \read "*a"
+
+      discount data, "toc", "nopants", "autolink"
+
+    with io.open "blog/#{@name}.markdown", "r"
+      @title = \read "*l"
+
+  render: true
+```
+
+And the view behind this page:
+
+```
+-- views/blog/post.moon
+import Widget from require "lapis.html"
+class Post extends Widget
+  content: =>
+    raw @doc
+```
+
+That's it. That even includes the extra overhead of caching the markdown as
+HTML in a key->value store called OlegDB (I will get into more detail about it
+below). With Lapis I can code faster and be much more expressive with a lot
+less code. I get the syntactic beauty that is Moonscript with the speed and raw
+power of luajit on top of nginx.
+
+### OlegDB
+
+OlegDB is a joke about mayonnaise that has gone too far. It has turned into 
+a full fledged key->value store and I think it is lovely.
+
+### Container Abuse
+
+I have OlegDB running as an in-container service. This means that OlegDB does
+hold some state, but only for things that are worth maintaining the stats of
+(in my eyes). Having a cache server right there that you can use to speed
+things up with is a brilliant abuse of the fact that I run a container that 
+allows me to do that. I have Oleg hold the very HTML you are reading right now! 
+When it renders a markdown file for the first time it caches it into Oleg, and 
+then reuses that cached version when anyone after the first person reads the 
+page. I do the same thing in a lot of places in the codebase for this site.
+
+---
+
+I hope this look into my blog's tech stack was interesting!
