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.

I'm so fed up* with articles about the widespread use of LLM chatbots by university students that only interview students who use them intensively and teachers who have no idea how to encourage students to think by themselves.

Aren't there any stories out there of students who refuse to use them because they realize how detrimental to learning this can be (I'm less interested in those who refuse out of ethical/environmental/geopolitical concerns, not that those aren't valid) or of educators who have found how to effectively encourage students to do their own work, because the point is not the final product but the process?

(Yeah, my Introduction to Data Science course is starting in a few weeks and I'm not looking forward to the time we're going to waste on grading projects written by an algorithm.)

* by which I mean, excessively upset and having difficulty sleeping at night. The despair they induce has even been seeping into some of my dreams.

Just rolled out some fediverse-related improvements:

- Now you can follow Write.as blogs from Ghost! There was a tiny bug with this that we just fixed. (WriteFreely PR: writefreely.org/pull/1373)

- We now support the `preview` property as a fallback for Articles. This will make your posts look much nicer as more platforms support it! (WriteFreely PR: writefreely.org/pull/1374)

"Who Broke the Internet?" is a new podcast from CBC Understood that I host and co-wrote - it's a four-part series that explains how the enshitternet came about, and, more importantly, what we can do about it. Episode one is out this week:

I'm glad to announce the release of version 2.76 of , the simple, minimalistic instance server written in C. It includes the following changes:

Added Webmention support for links (Markdown-style or direct) written in a post.

Added new command-line options for list maintenance.

Display custom emoji in more places (contributed by dandelions).

Mastodon API: fixed infinite scroll in many clients (thanks to cheeaun for giving me the clue), added /api/v1/accounts/.../lists endpoint (contributed by dandelions).

Email notifications can now be sent via libcurl SMTP instead of spawning the /usr/sbin/sendmail program. To use this new feature, some additional server configuration is needed, see snac(8) (contributed by shtrophic).

Do you know why most sysadmins & experienced DevOps folks like to use ? It's because learning all of Vim's (A-Z) commands actually grants the user temporary telepathic abilities. You see it all the time. All hardcore Vim users, like those sysadmins, often seem to anticipate your needs before you even type them. They can practically fix server /cloud issues by editing text config files or deploy Ansible playbook before they even happen! Vim gives them superpower. I have spoken

We're excited to announce that we've implemented RFC 9421 (HTTP Message Signatures) in , complete with our double-knocking mechanism to maintain backward compatibility with the draft cavage version.

This implementation includes both signature generation and verification, meaning is used when both sending and receiving activities. While we haven't merged the RFC 9421 implementation branch yet, we're currently conducting interoperability tests with development versions of Mastodon and other implementations. Once these tests confirm compatibility, we'll proceed with the merge.

As noted in the attached docs, although RFC 9421 is the final and official standard for HTTP Signatures, the draft cavage version remains widely used across the . Our double-knocking mechanism ensures maximum compatibility by trying the RFC 9421 version first, then falling back to draft cavage if needed.

Currently, we support RSA-PKCS-v1.5 key pairs for generating HTTP Message Signatures, with plans to expand to other signature types in future releases.

We look forward to contributing to a more standardized and secure fediverse!

HTTP Message Signatures

This API is available since Fedify 1.6.0.

RFC 9421, also known as HTTP Message Signatures, is the final revision of the HTTP Signatures specification. Although it is the official standard, it is not widely used in the fediverse yet. As of May 2025, major ActivityPub implementations, such as Mastodon, et al., still rely on the draft cavage version of HTTP Signatures for signing portable activities.

Fedify automatically signs activities with the sender's private key if the actor keys dispatcher is set and the actor has any RSA-PKCS#1-v1.5 key pair. If there are multiple key pairs, Fedify selects the first RSA-PKCS#1-v1.5 key pair among them.

NOTE

Although HTTP Message Signatures support other than RSA-PKCS#1-v1.5, Fedify currently supports only RSA-PKCS#1-v1.5 key pairs for generating HTTP Message Signatures. This limitation will be lifted in the future releases.Double-knocking HTTP Signatures

This API is available since Fedify 1.6.0.

As you read above, there are two revisions of HTTP Signatures: the draft cavage version and the RFC 9421 version. The draft cavage version is declared as obsolete, but it is still widely used in the fediverse, and many ActivityPub implementations still rely on it. On the other hand, the RFC 9421 version is the official standard, but it is not widely used yet.

To support both versions of HTTP Signatures, Fedify uses the double-knocking mechanism: trying one version, then falling back to another if rejected. If it's the first encounter with the recipient server, Fedify tries the RFC 9421 version first, and if it fails, it falls back to the draft cavage version. If the recipient server accepts the RFC 9421 version, Fedify remembers it and uses the RFC 9421 version for the next time. If the recipient server rejects the RFC 9421 version, Fedify falls back to the draft cavage version and remembers it for the next time.
