Hackers' Pub is a place for software engineers to share their knowledge and experience with each other. It's also an ActivityPub-enabled social network, so you can follow your favorite hackers in the fediverse and get their latest posts in your feed.
Within the context of threaded discussions, contexts (aka "topics", "posts", "threads", etc.) are associated with an audience (aka "forum", "category", "community", etc.).
What happens currently when a context is moved from one audience to another? How does ActivityPub enabled software communicate this?
I recently moved this topic from one category to another, and in doing so, realized that I have absolutely no idea what happens to the group association as seen by other software.
@rimu@piefed.social also said in the other thread:
Also moving what NodeBB calls a topic (a post in Lemmy/PieFed) from what NodeBB calls a category (community in Lemmy/PieFed) into a different category (without spawning a new topic or leaving the old copy behind) is much needed but not implemented in Lemmy/PieFed/Mbin.
One solution would be to federate an Update activity, though this is problematic because audience, the relevant field in question, is on its way out.
Another solution would involve the Move activity, which would be an explicit signal that something moved somewhere. In this case, the Move would indicate the context moved to the new audience, or in AP software that have not implemented FEP 7888, then the top-level object will have moved to the new audience.

….MATH, people, MATH. With THAC0 you had to do actual math every time you took a swing at Ettin or something and every time they swung back at you. No more. Now it’s de-mathed. It’s making our children and odd adults stupider. Now, let me move on to Blibdoolpoolp: hot or not?

Huge respect for 
@j12tJohannes Ernst for cancelling #fediforum and taking time to reflect, listen and learn. I'm really sad that we didn't get the event this time, but there has been a good discussion around the issues and future opportunities.

高くなったのはDBの金額とかオブジェクトストレージですね。
長く利用されたいのであればDBの従量課金は洒落にならんです。
ちなみに、3年前は$15(1500円)くらいでした
3年くらい雑に構築したおひとり専用インスタンスを維持すると5000円くらい月にかかります。
最適化してないし、自分の快適のためなので払います。

Our #cat has three modes: sleeping, eating, and looking at me until I give her food.
If any of that annoys you, then look to the #MirrorPrinciple and ask yourself what the cat has in abundance and which you lack. Self-esteem? Love of self? Full enough of love to give generously? Too little I-don't- give-a-eff?

Many speculated that #Betula can be turned into a microblogging server easily. It's true, one only has to hide the bookmarked URL, writing the text in the bookmark description.
Paying attention to the rising popularity of microblogs around the world, we've decided to make Betula into such an application. The next version, v2.0.0, will be the start of the new era. We'll focus on compatibility with the leading platforms such as #honk and #snac2 first.

Most people know that you use a leading, upside-down question mark before the question in Spanish:
¿Me puedes traer el yoyó?
…and the same for exclamations:
¡Rompiste mi yoyó!
…but many people forget that if you have a sentence that ends with an emoji, you also need to use an upside-down version of the emoji before the sentence:
🙃 Me gusta tu yoyó rosa 🙂
So, I went to #Lyon. It was great. I rode bikes, the family came with me. They want to get there quickly. I want to go on trains. Classic compromise. We’ll fly out together, and I can get the train back if I like. Ok then. 1/n
The Viewsonic 5k monitor has gone up in price by $100? That's really weird.

So the cishets are trying to cancel Chappel Roan again and saying she needs media training and to be nicer.
Fuck that, I think she needs to be meaner and more unfiltered.
It's a simple joy, but I do love the ability in mutt(1) to use `#` and `&` to repair broken message-threading. Something that is nigh impossible in most other MUAs.

The sensors framework can now output JSON. No, this is not an April Fools joke.
I kinda don't like how my personal site uses GitHub pages which uses Ruby and Jekyll, and I have no idea really what it's doing 
it would be nice to use my own web framework library to generate static sites
