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 lot of Fediverse software has a HEALTH-CHECK URL.
But not all Fediverse does.
It would be better if ALL Fediverse software had a HEALTH-CHECK URL.
...
A HEALTH-CHECK URL is a special URL that tell others if the system is running properly.
It would return "200 OK" if everything is fine. And return "500 Internal Server Error" if there is a problem
...
A HEALTH-CHECK URL is important to those who actual run and administrate Fediverse servers
@reiver@reiver ⊼ (Charles) 
it would be a useful check for all servers. /.well-known/hostmeta.json per RFC 6415 is probably a good candidate, but /.well-known/health or something similar could also work.
I've been reflecting lately on projects like 
, and 
@botkitBotKit by Fedify 
. Sometimes I wonder if I'm solving problems that very few people actually need solved. How many developers truly want to build their own #ActivityPub server from scratch?
It feels a bit like inventing shoes that let people walk on their hands all day. Would there be a viable market? How many would actually buy them?
That's the sense I get with these projects. They do have users who find them tremendously valuable, but the total user base is inherently limited. The tools serve an important function for a small audience of specialized developers.
There are moments when my motivation wavers. When the user community consists of just a handful of enthusiastic supporters, it's sometimes difficult to maintain momentum and justify the ongoing investment of time and energy.
And yet, there's something meaningful about creating specialized tools that solve complex problems well, even if they're only used by a few. Perhaps that's enough.

The men who have been subject to Trump's version of extraordinary rendition must be returned to the U.S. - period. This action was UNCONSTITUTIONAL and violated domestic and international laws. It is a human rights abuse, perpetrated by the US gov't.
It doesn't matter if they are "innocent" or "guilty" - EVERYONE on US soil is subject to the laws of the land - including the right to Due Process.

현재의 이른바 “에이전틱” 코딩 어시스턴트들은 종래의 정적 분석 기술을 활용하지 못하는데, 아마도 머지 않은 미래에 둘이 결합될 날이 올 것 같긴 하다. 다시 말해, 애초에 LLM이 컴파일조차 안 되는 코드를 뱉지는 못하게 할 수 있을 거라고 생각한다. 그 때가 되면 정말 평균적인 사람 프로그래머가 이룰 수 있는 품질의 코드를 내놓을 수 있지 않을까? 컴파일도 되고, 겉보기에는 잘 돌아가지만, 몇몇 코너 케이스에서는 여전히 깨지는… 그럼 그때는 또 LLM이 QA도 하고 코드 리뷰도 해서 고치는 미래가…!?

He fabricated evidence.
While this is a big deal, even if the evidence were valid, being a member of an organization is not a valid reason to lock them up. You have to actually prove that he committed a crime. This is constitutional rights 101.
It's certainly not a valid reason to extract them to a death camp on foreign soil.

is it more environmentally responsible to do sudoku on the computer (power draw, the infrastructural cost of the internet) or on paper (single-use synthetic rubber used for pencil eraser, production of pencil lead, paper use)
genuinely this one is starting to wonder. (assuming that it uses a computer it already owns and thus does not cause production of computers in order to do sudoku)

Building ActivityPub @index@activitypub.ghost.org
We've been shipping hard in the last week, and we've got more ActivityPub updates to share for those of you who are trying out the beta!
Last week, we recapped the top feedback we've received so far around what's working well about ActivityPub; and what isn't. This week, we're addressing the request that has been sitting firmly in the number one spot.
Up until now, all users of ActivityPub in Ghost had a simple, fixed username of @index@domain.com. And, if your domain included www then the username would be @index@www.domain.com.
Now, the www prefix has been automatically removed from all usernames, and you can customize the @index part to anything you like!
This a first step to give you more control how people see and interact with your profile in the Fediverse, and you can expect more settings like this to be added as we go.
One of the other common questions we've had lately is whether Ghost will allow multiple staff users within a website to have separate usernames. The answer to that is: Yes, that's that plan. But we're not there yet.
Eventually, we're hoping to make it so that you can have a publication-level profile like @index@404media.co that contains all posts, from anyone on the site — as well as staff user profiles like @jason@404media.co and @sam@404media.co that represent posts and interactions from those individual authors.
This part, though, is still a way off.
Making it possible to support multiple users within a single Ghost install is a significant piece of work, and there are many other things we're hoping to get working first. Like, for instance, support for @mentions and being able to add images to replies! (Foreshadowing)
