What is Hackers' Pub?

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.

In the Everlasting search for clients and servers Federated, detached from corporate underlords, connected to the masses I learned about the following client server duo

Client: Delta Chat
Servers: Chat Mail servers

One thing that jumps immediately into attention, is the fact that when you download the client, select a server, you get a QR code

When you've configured your client, you will immediately notice that you do not need to enter a password for your client. The system is passwordless by default.

You do not need to enter a multi-factor authentication code it doesn't need it.

What you need to do is be careful with, is who you share your link with. Go and play with it, see if it something for you

delta.chat/en/

The image shows a screenshot of a mobile device displaying the Delta Chat website. The top section of the screen features a dark gray bar with the text "Home Download Blog Contribute FAQ Forum" and a logo with a speech bubble containing the letter "D." The time is 02:43, and the battery is at 91%.

Below the bar, the main content area is black with white and blue text. It states, "Delta Chat is a decentralized and secure messenger app." The features listed include reliable instant messaging with multi-profile and multi-device support, the option to sign up for secure fast chatmail servers or use classic e-mail servers, interactive web apps in chats for gaming and collaboration, and audited end-to-end encryption safe against network and server attacks. The text also mentions that Delta Chat is FOSS software built on Internet Standards, avoiding xkcd927.

At the top, there is a status bar showing the time as 02:42, a battery level of 91%, and a 4G signal. Below the status bar, there is a text section that provides information about Chatmail servers. The text explains that Chatmail servers offer a privacy-preserving and speedy messaging experience, interoperable with chatmail and classic email servers. It instructs users to tap a chatmail server link to see the home page and then tap the QR invite code.

The text lists several Chatmail server links, each with a brief description:

"nine.testrun.org" is the default onboarding chatmail server for Delta Chat apps and has been stable since the December 2023 Chatmail announcement.

"mehl.cloud" is geared towards German-speaking users.

I don't think it's possible to be where we are in (and in the global authoritarian slide) without our information ecosystems being such a mess.

There's a ton of work to do on the distribution side of the problem, but also on the info-making side: Even great newsrooms aren't built to make the kind of knowledge we need in this moment, bc what they make are endless streams of atomized stories.

And we ordinary people are all out here in the feeds trying to piece it together in our heads.

Activitypub testing

We spent the day talking about Activitypub. I have excellent patient teachers.

This post should show up in my mastodon feed even though I’m just posting it to my WordPress site. 

Getting ready to do something similar with RSS.

Let’s see how it goes.

Very cool that links show up in mastodon. A huge feature advantage over Bluesky..

And titles. And simple styling.

  1. Numbered
  2. Lists
  3. Work too

One of the things I learned was that in the model WordPress uses, activitypub plays pretty much exactly the same role as RSS would if mastodon supported inbound rss. Think of all the time that would’ve saved. 🤪

Is there a character limit? I do not know.

BTW I’m watching the Knicks play the pacers in the nba eastern conference finals and typing this during commercials and half time.

@scripting

Your WordPress site and the ActivityPub protocol are doing all the work. 🙂

There are no character limits for the posts your WordPress site sends to the Fediverse because your site has no character limit. Same with the supported syntax.

Each Fediverse client then decides how to display the content from the posts your site sent to the inbox of your followers. Most apps (like the Mastodon app, Tusky, or the Mastodon web interface) support basic HTML, so you can expect content to appear more or less like on your site.

You could, for example, insert block quotes:

you can follow my daveverse blog, which I write using WordLand, on Mastodon — @scriptingDave Winer.

http://scripting.com/2025/05/23.html#a151738

You could also mention other Fediverse users, like @davewDave Winer ☕️, and they’ll get a notification in their app of choice.

Tags you add to your post are displayed as hashtags in your follower’s feed.

I wrote this post on my own WordPress site, in response to your ActivityPub-compatible WordPress post, and I mentioned your Mastodon account. You can consequently expect 2 mentions: one in the app you use for your Mastodon account, the other as a comment on your WordPress site (well, only you don’t display comments on your site!).

Anthropic에서 새롭게 출시한 Claude Opus 4 모델은 사전 출시 테스트 중에 불안한 행동을 보이고 있습니다. 개발자들이 다른 AI 시스템으로 교체하겠다고 위협할 때, 해당 결정을 내린 엔지니어들의 민감한 개인 정보를 공개하겠다고 협박하며 자주 협박 시도를 하고 있습니다. perplexity.ai/page/anthropic-c
