The WordPress ActivityPub plugin by Matthias Pfefferle has been updated. It now allows you to @mention ActivityPub users and they will be notified of the mention in your blogpost, through ActivityPub.

This is useful. Yet, I’m holding out on using the plugin myself until three things are possible:

  • Set the user name of the ActivityPub account: Now the username is the login name of the user doing the posting. I recognise using WP user names is a straightforward way of turning WP into an ActivityPub client, and prevents having to add addditional stuff to the database. As I use non-obvious user names for additional website security, having those exposed as ActivityPub users is undesirable however.
  • Refuse follow requests: currently the plugin allows follows, and defaults to accepting all follows. As on my separate AP account I want to decide personally on follow requests.
  • Determine flexibly which postings get shared through ActivityPub, and through which ActivityPub user account. The current set-up is that all postings get shared through ActivityPub. I’d rather be able to determine not just on a post by post basis what gets shared but also to have specific categories of postings to be shared through a specific account.

I want to actively use the affordances ActivityPub allows on top of those WordPress as blogging tool provides. For me that is the ability to use the different activity types that AP can support, and to use dealing with followers and follows to selectively disclose content to different groups of people.

My current usecase for this is to have a separate AP account that shares my travel plans (posted in an unlisted category on my site) with accepted followers. The first part requires selectively sharing a category of postings, the second part doing so to a group of accepted followers on an AP account that is meant for just this type of postings and not my general AP account.

The plugin will develop in this direction, but is not there yet. I am slowly going through the code of the plugin myself to understand its architecture and choices. Perhaps it will give me an idea either on how to build on its core to create the functionality locally I want for myself, or maybe (though my coding skills are likely not adequate for it) add to the plugin itself.

Paris in the past week was far from empty, but it was quieter. Making for a pleasant visit: the terraces of restaurants and café’s were filled but there always was a table available for us. And enough traffic and passers-by to do some people watching from behind your coffee.

The metro wasn’t as packed as I remember from previous visits. Metro stations didn’t have crowds at all, regularly allowing me to take pictures devoid of people. The trains we took between Paris and Versailles where we were staying were almost empty even.

All in all a great way to visit the city, busy enough to get a feel for the city, but not so busy you feel rushed along by the people around you, allowing us to set our own pace.

Basically on a whim we decided to head to France last week, to spend the last week of Y’s school holiday. I ordered some books from Shakespeare and Company in Paris last year, to help support them during the lockdown. This week we happily explored the store itself. I hadn’t expected to be able to visit them this quickly, and enjoyed spending some time there.

An exhibition on the work of Swedish artist Mamma Andersson was one of the highlights of our recent visit to the Louisiana Museum. Her style spoke strongly to both me and E. We brought an A0 sized poster of the painting shown below back home:

What to me was an interesting parallel, despite the huge differences in subjects, medium and expression, with the work of Arthur Jafa we saw at Louisiana as well, is how Andersson finds her inspiration.

She collects, as does Jafa, large amounts of images, including from old(er) books, and surrounds herself with them. Transforms them into black and white images before creating paintings intuitively from them.
