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.

The postmortem OpenAI just shared on their ChatGPT sycophancy behavioral bug - a change they had to roll back - is fascinating! My notes here: https://simonwillison.net/2025/May/2/what-we-missed-with-sycophancy/
@hugh In addition to the concerns expressed here, I argue in my book that Mastodon's status as the single largest ActivityPub implementer back in 2017 is a factor -- after all, Mastodon had an API at that point. People making clients chose to make them compatible with Mastodon's API instead of redoing everything for the then-new C2S spec.
@rwgRobert W. Gehl @hugh Pragmatically speaking, that's true because people needed to build/show something. But there are gaps in the specs such that broad interop is technically not possible as it stands ( https://w3c.social/@csarven/114178482096355457 ). I'm not saying this to dismiss any work (especially one I was involved in since the days of Laconica/StatusNet). I'm coming from the perspective of how different classes of products can interoperate, regardless of the umbrella or spec "camp" they're part of on the web platform.

@hugh According to one dev for GoToSocial:
"Implementing the C2S API is, I'm afraid, really out of the question, as it's totally underdefined, relies on the client to do almost everything, and would be an absolute nightmare project for us. That's a non-starter."
https://codeberg.org/superseriousbusiness/gotosocial/issues/3846#issuecomment-4018586
@skyfallerNelson @hugh relying on the client IS the point. It gives people sovereignty over their Fedi presence, and leaves the processing and other server things for the server.

If you write code to make websites (HTML, CSS, JS, Web API, Media) and you get frustrated trying to wrangle your code to work in Safari, which bugs are blocking you? Which existing features would you most like to see improved? If you got a chance to order priorities which effort would you put first?

又到了五月，各家廠商都開始為了母親節拼一波優惠，感覺從今年才開始出現「母檔」這種奇怪的用語，不知道是不是又是中國用語入侵？
但比起什麼母檔我更討厭那種奇怪的撰寫母親有多偉大的煽情文，譬如我買過的襪子廠商：
「早就習慣了，她會記得我們所有的小事，
我們的「沒空管」，她一一收拾好；
忘了的瑣碎日常，她從不漏接。
永遠知道襪子放哪、藥膏收哪、什麼該洗、什麼該曬，只靠幾乎是本能的母愛，無私的為我們打理生活。
但我們從沒想過，這世界上，有誰記得她的小事？」
………我真的沒有這種媽媽耶？那不知道是誰的媽媽？總不會只有我沒有這種媽媽吧……

Hey fedi, I need some help!
I am trying to connect an application I am making with the Fediverse. When I search for an actor I am successfully able to get to the profile (yay) but when I search for a post I cannot find it.
I am receiving the GET request and am sending the response with the content type ("application/activity+json") (for example):
{
"@context":"https://www.w3.org/ns/activitystreams",
"name":"New Note",
"type":"Note",
"id":"https://critters.jpleite.eu/posts/1",
"attributedTo":"https://critters.jpleite.eu/users/1",
"content":"Hello there!",
"to":[]
}
Why would Mastodon not display the post?
The on Mastodon’s side is returning 403 action not allowed.
Thank you

"Sinclair in his quest for miniaturisation, to produce a true pocket calculator, wanted to use button cells rather than normal batteries, but these would be drained in minutes by the chip and the LED display. However, Chris Curry and Jim Westwood...found that the power to the chip did not have to be on continuously, it could be pulsed and the internal capacitance of the chip would store enough electrical charge to keep it working till the next power pulse. Power pulses lasting 1.7 microseconds are used, at a frequency of 200 KHz during calculations and 15KHz between each operation, reducing the power consumption to 25 to 30 mW. Texas Instruments did not recommend operating in this way, but it allows the Executive to get about 20 hours continuous operation from 3 small mercury button cells."

@naturzukunft
> rdf-pub.org is providing c2s
Awesome, so that's at least 3 server packages to test clients against. Pleroma, Epicyon, and rdf-pub.org.
@smallcirclesjust small circles 🕊 @skyfallerNelson @hugh @bob
@strypey@mastodon.nzoss.nz @naturzukunft @smallcirclesjust small circles 🕊 @skyfallerNelson @hugh @bob There are other servers that implement C2S support (ActivityPods, Vocata, onepage.pub, ...). Lack of servers implementing C2S is not the problem. See the many other issues described in this thread for examples of why one can't built an *interoperable* AP C2S client with features a typical user would expect.

@smallcirclesjust small circles 🕊 @skyfallerNelson @hugh @bob
@strypey@mastodon.nzoss.nz fwiw I'm thinking that C2S might be applicable in an S2S-like setting where a user "logs in" to instance B using instance A's credentials, and B can do limited actions as the user on A. Essentially A would act as the server, B is the "client".
Can't wait to get some “Your IP Address has changed notifications”!

@mariusormarius no problem. Thank you so much for taking time to help <3
PS. You can use https://browser.pub/ to debug your activitypub objects. It's a very useful tool developed by a community member. On a first glance your note looks fine through it. :)

Just read a saucy article on dbushell.com by David Bushell, 
@dbDavid Bushell 🥐, about the decline of Deno, and found the "alternate version for non-hominids" quite entertaining. From there I found llmstxt.org, an ad-hoc standard for ... helping large language models read your website, and llmstxt.site, a list of sites which are ... trying to make things easier for LLMs. It seems that a human reviews submissions there, so I don't suppose the list is ... polluted by folks trying to gum things up. I doubt, for example, that that guy the other day who put zip bombs on his website would make it through such a review. But it's important to ... advance human knowledge ... by giving the LLMs plenty to read, isn't it?

@AnxiousBadgerDani(ela) 
on a first look I would skip encoding the properties which are null like InReplyTo, CC, Summary and Tag.
But I don't really know much about the mastodon code-base to be certain about that being the problem.
Another thing, which I had trouble with myself on my projects, is the date representation, Mastodon can't handle (or couldn't at some point) dates with below second precision. Try to use a more common date format, and also include a timezone.

@The_TimTim Ellis 🦝 I feel like the real joke is that the sign says "forbidden for bicycles" :)
@mariusormarius Having not been to Europe myself I assumed (as I'm guessing the artist did) that it would need a line through it to indicate forbidden. I have now looked this up and realized that white background, red circle = forbidden, while blue background, white circle = only this type allowed.
Guess the artist should have inverted the sign. Here, I fixed it.
