I've noticed other photos from my side of the country look similar to my own ones. I assume this is due to the light reflecting off the sea, the angle of the sun, and the cloud cover. The colour of the grass is also duller than many places.
Sourcehut: minimal (non-github) interface, very modular, email workflow.
Cgit / Gitweb / etc.: just a git interface, no specific workflow.
If you're not using any of the additional features, cgit should be enough. If you're planning on collaborating with others, probably Forgejo would be better.
You can also use individual components of sourcehut, if you want a git web interface with just issue tracking, ci, or wiki, for example.
I assumed it was communication between cats. Mine do it to eachother, usually when they get home. Sometimes they do it to me as well. They also do it if they see something out of the window though.

When you install whatsapp, if you deny it permission to access your phone number, or if it doesn't find one, it allows you to enter a phone number manually. It then sends a confirmation text with a code to verify the number, just like any other website.
I used an old (non-smart) phone with a burner sim to receive the confirmation text.
The first thing I do is navigate to addons.mozilla.org. It's usually listed somewhere on the homepage.
