mat~wiki is the Wiki you are currently visting. I realised that, with the way my actual website is managed and written, I couldn't just drop in random stuff. Then I remembered about vimwiki. This plugin is quite convenient to write down ideas and stuff, and also has a quite powerful HTML converter!
I needed a place to publish notes and write a diary. Some of the resources are password-protected because I do not wish anyone to read these. But most of the resources are publicly available to share my knowledge, to share my interests, to share my projects.
This place will also now host the documentation of my future projects.
If you want to host a website like mine, I suggest you to take a look at /prog/vimwiki. It shows you how the infrastructure has been made and how to host it yourself using NGINX, vimwiki and OpenSSH.
