Hi! My name is Juan Castro.

  • I don't have social media, just a mastodon account that I don't use very often

Software I use

  • OS: Arch Linux, btw.
  • DE: KDE Plasma 5. When I want to feel like a super hacker, then dwm or herbstluftwm. Recenlty I been trying Sway.

  • Office suite: Libre office, I don't use it very often though

About the site

This webpage is generated with the help of Hugo. Before it was generated from org-mode files thanks to org-publish, but I migrated to Hugo so it's easy to mantain two languages and and RSS feed. The server is a VPS by Vultr running Debian 10, and the site is served by nginx.
