+This website is running as a *Mirage unikernel*.
+A traditional application is one or more programs that run in an operating system on a computer alongside other programs.
+A *unikernel* is a program that is also an operating system.
+That sounds boring -- an operating system where only one program ever runs?!
+And that is correct, this is often not what you want.
+Luckily, modern machines have the capability to run many *virtual machines*.
+This provides some benefits:
+
+- A virtual machine is well isolated from other virtual machines.
+  You don't have to worry about one application messing with the files of another,
+  or a malicious application sending the private bits from another application somewhere where it doesn't belong.
+
+- You know what your application needs from the operating system, so you can leave out the things that are not needed.
+  This simplifies things, makes the operating system much smaller.
+  Furthermore, it's a big security benefit - every bit of code is a potential security issue.
+  Only a few years ago it was a huge problem for many people because their virtual machine had a vulnerability in the virtual floppy drive!
+
+- The program is self-contained.
+  All that it needs is packaged up in the unikernel.
+  In traditional software you often have a number of dependencies that you need on your computer in order to run the application, and they all need to have a compatible version.
+
+This website is using a *library* called [Canopy](https://github.com/Engil/Canopy) that a guy I met in Morocco and later Leipzig wrote.
+The first thing it does when it starts is to fetch files that are under *version control*.
+This means the files have a log of what was done, and every change is tracked.
+You can go back in time if you regret a change!
+I made the files public on a website hosted by my friends [data.coop](https://data.coop/).
+Whenever I push new changes there Canopy makes sure to get the latest updates.
+You are welcome to take a look at the history: [https://git.data.coop/reynir/frontloberne](https://git.data.coop/reynir/frontloberne)
+Canopy knows how to make the simple text files look pretty in your web browser.
+
+On the same machine I run another Canopy instance which serves a technical blog at [blog.mirage.reyn.ir](https://blog.mirage.reyn.ir/).
+At the moment I'm only running a few other things, but I could easily run 100s of instances.

+Open source is a philosophy of sharing knowledge and know-how.
+You share how things work, be it software, beer recipes or how to grow oyster mushrooms from spent coffee grounds.
+You are free to read, inspect and modify the code (recipe) in any way you like.
+In some cases, extra conditions apply such as you have to share back any changes or improvements you have made if you're not using it just for personal purposes.
+In other cases no conditions apply.
+
+Pretty much all my work is released as open source.
+It is something I believe in.
