I used to have a monolithic html page for blog posts at /blog, but it was neither practical nor sustainable.

I am now using Jekyll, a tool that allows me to separate posts in different Markdown files. For those who are interested in learning more about Jekyll, this blog post was helpful to me.

As a consequence, for those who used the previous version of this blog, you now have:

A main page, listing all the posts, sorted by date of publication
When you click on a link on that page, you have access to the requested post’s page
