So I feel like I finally made a hands-on contribution to a #FreeSoftware project:
https://gitlab.archlinux.org/archlinux/packaging/packages/dillo/-/issues/3
I found out that #dillo in Arch Linux can't browse IPv6 sites as the support is not explicitly compiled in. Rather than discussing it here, I decided to go straight to the maintainer's repo with the fix.
I feel happy, even if a little silly for some reason. I never did a technical commentary like this before, and if it gets merged it's my first real contribution to a project!
