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.
A big round of congratulations and thanks to 
@teamtootTîm Tŵt Staff and 
@newsmastNewsmast Foundation for the launch of the new Tŵt Wales app. Focusing on community is how we build the Fediverse.

Does anybody know what web sites I could go to to find some sloppy hot takes about current events? Because Mastodon and the entire concept of the fediverse is magically impervious to those on principle, I'm going through a lot of withdrawal today. It's like a desert out here!

Before going to bed last night, a friend told me they were already hearing bombs dropping (in the Middle East, but not in Iran or Israel). Their flights back to the US got cancelled.
Millions of people who don't want a war dragged into it anyways. I'm praying for the living and mourning the dead.

Next up 
@michaelMichael Foster is up talking about the launch of the Qlub app and the Tŵt app, and how US tech giants don't share the same community values of the towns and communities we live in. #TootWales
Next up is @newsmastNewsmast Foundation to share more about their Apps For Change program which the new #TootWales app is a part of.
We've loved working with them just as much as they have with us. Team work to make the Social Web accessible for more people.

My mastodon stream ranges from complaints that AI is slavery to lectures on how we need to stop using words like "think" to describe them. Chains of transformers have really made people lose their minds.

Heading to the #TwtCymru event or only able to join us in spirit? If you see something that evokes "toot", "tŵt", "dwti" or anything Welsh, send something to today's FediWall with the hashtag #TootWales
And follow along with this self-updating wall of toots: https://fediwall.social/?servers=mastodon.social&tags=tootwales,twtcymru,pethaubychain,littlethings,bettersocial,defaidodon,cymru,cymraeg&accounts=teamtoot@toot.wales&hide=nsfw,boosts,bots&ban=pubeurope.com&title=T%C5%B5t++Cymru+%7C+Toot+Wales+Fediwall&theme=light&interval=30
Ultimately I try to be grateful for the duality that I can see and feel because I think that navigating this requires having compassion for all these sides of ourselves. Being an ambitious person, with many years of skills, who gets joy out of creating, but also being a person in a world that is very happy to take advantage of creative and ambitious people past their limits. Knowing it is true that collectively my beautiful queer household starts further back always, this is just reality.
You have to find ways to fight that aren't grinding. You have to find paths to work hard that feel meaningful, like the rewards flow back to you and not to everyone else. You have to take the world as it is yet continually and always expect it to be far better than you have experienced. It is a lifelong challenge.

Big thank you to Elena for her hard work on the video.
I don’t know what the hell ICE / CBP / FBI?? / other feds are up to, but we’ve had several •huge• swarms of federal vehicles rolling out these last few days.

You're here because you care, or you really like pies!
@jazjaz and the Team Twt staff care too.
If #TootWales or the broader open social web gives you what you need, provides you with connections that are meaningful to you, or brings you joy - tell your friends!

Today 
@kopperkopper 
shared a post on the fediverse titled how to not regret c2s, and I found it genuinely interesting to read, even if I'm not sure its proposed architecture actually solves what it sets out to solve.
The author's frustration with naïve #C2S implementations is well-founded. Slapping an #ActivityPub facade onto an existing Mastodon-like server and calling it C2S doesn't buy you much—you end up with the rigidity of a bespoke API without any of the interoperability C2S is supposed to offer. The “JSON-LD flavored Mastodon API” framing is apt.
The proposed solution is to split responsibility more aggressively: the C2S server should be nearly stateless and dumb, storing ActivityPub objects without interpreting them, while a separate “client” layer handles indexing, timelines, moderation, and exposes its own API to the frontend running on the user's device. It's a clean separation of concerns on paper.
But here's what bothers me. When you map this architecture onto familiar terms, it looks roughly like this:
That's not a new architecture. That's just the current architecture with the labels shifted. The interesting question is which interface gets standardized, and the author's answer is the one between the C2S server and the “client” layer—the bottom boundary.
The problem is that what people actually want from C2S is to connect any frontend to any server. The portability they're after lives at the top boundary, between the frontend and whatever is behind it. But the author explicitly argues against standardizing that layer: “we don't really need a standardized api,” they write, leaving each client free to expose whatever API it likes.
Which means frontends remain locked to specific clients, just as Mastodon apps are locked to the Mastodon API today. The interoperability promise of C2S—log in to any server with any app—isn't actually delivered. It's been pushed one layer down, out of reach of the end user.
There's real value in the post's thinking about data hosting vs. interpretation, and about the security implications of servers that understand too much. But as an answer to the question C2S is supposed to answer, I'm not convinced.
One of these days, I won't be able to keep up with the amazing 
@astro community... but I live to fight another month!
