Source code

I’m a programmer who believes in Free Software, that’s why I release my programs under Free/Libre licenses. You can check out those programs on my sourcehut account

This site’s source code, along with the articles in Markdown can be found there too, at https://git.sr.ht/~arielcostas/website.

RSS

I don’t want to maintain a newsletter, having to write an email every day to my subscribers and get a whole bunch of addresses just for you to follow my content.

RSS is Really Simple Syndication, a feed system that allows users to subscribe to websites in a standarized format. You can use a Free Software aggregator like Thunderbird or via emacs' GnusRss, among others.
