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.

Just had a small, probably-never-going-to-happen thought: what if Lobsters implemented ActivityPub? My account there is hongminhee, so I'd get a @hongminhee@lobste.rs actor, and tags like #rust or #programming could be Group actors you could follow from Mastodon or anywhere else. Comments would federate as Notes, so you could boost a thread you found interesting without ever leaving your home instance.

The tricky part is that Lobsters is invite-only by design, and that culture would be hard to reconcile with an open fediverse. You'd probably want to keep writes gated behind a Lobsters account while making reads public. Lemmy did something similar, though it still struggled with spam after federation. Anyway, it's open source, so maybe someone with more time than me will take a crack at it someday.

오 시장이 후보 등록에 나선 것을 두고 당내 압박에 물러선 것이란 평가가 나온다. 이번 재공모가 공천관리위원회의 최후통첩 성격이란 평가가 나오는 데다, 박수민 의원(서울 강남구을)이 이날 서울시장 출마를 선언하며 장동혁 지도부에 ‘플랜 B’가 마련된 게 영향을 미쳤다는 것이다. 장동혁 지도부가 전날 오 시장의 인적 쇄신 요구 대상으로 거론돼온 박민영 미디어대변인 임기 연장을 보류한 만큼 오 시장도 강경 기조를...

‼️ is deprecating the Span Events API.

Our aim is to remove the confusion and duplication caused by having two overlapping ways to emit events: span events and log-based events. New code should write events as logs that are correlated with the current span. The older "span events" style will be phased out over time, but existing data and views that show events on spans will keep working.

Read our latest post to learn more about how you can prepare.

@reiver ⊼ (Charles) :batman: shared the below article:

Native discovery of related tags (fedibuzz/tags.pub)

julian @julian@activitypub.space

<p>I was talking to my marketing guy about integrating a tags-based onboarding workflow for freshly installed forums.</p> <p>The gist of it is, the forum admin adds a couple tags for the forum to globally follow, and achieves this via fedibuzz relay or tags.pub. Auto-categorization rules are automatically added and the forum starts receiving new (highly relevant!) posts through the magic of hashtag+federation ✨</p> <p>He then asked whether it was possible to suggest related tags (e.g. add <code>guitar</code> suggest <code>acousticguitar</code>, <code>electricguitar</code>, etc.) for the admin to also add, to which I replied in the negative "for now".</p> <p>But that got me thinking, is this something fedibuzz or tags.pub could achieve/offer in its API?[...]</p>

Because mastodon is like a 99% male audience, I will say this: if you have an aging mother you are in relationship with and care about, do NOT make her go through medical stuff alone. I am skilled & mean enough to fight through medical stuff and even so you would not believe how bad it is. Just accept that you cannot imagine.

I talk to a lot of people's aging moms and they are abandoned & alone even in nice families. I don't care how awkward it is, you have to try to ask them about it.

I spent the last week or two configuring a CI/CD runner for on , here's how I did it.

I wasn't really finding in-depth documentation and blog posts, and in particular none of the published examples would build container images--the biggest limitation of Codeberg's offering.

So I fixed it.

New blog post introducing the WIP Duranium project (immutable postmarketOS), some of its major features, and explaining why some design decisions were made. :blobcatthink:

> Either the new image works, or the system falls back to the previous one automatically. No partially-applied state. No debugging audio when you need to make a phone call and no fussing with a broken web browser when you just want to doomscroll cat photos. It also means developers can reproduce the exact state of a user's device, making it much easier to track down and fix issues.

After Madblog, how many of you would like #ActivityPub and #Indieweb support to come to GPSTracker too?

This is an idea that I’ve been flirting with for a while.

Like many Millennials, 10-15 years ago I was into the Foursquare-mania. It was the age where pubs would offer discount to their Foursquare mayor and where people used to share their Foursquare stats and compete on how many badges they had collected.

Then Foursquare decided to pivot its platform towards the business-side instead, the check-in app was spun off into Swarm, it gradually lost users but it gained trackers, and by now I think only 1-2 of my contacts (out of >100 in the golden age) still use it.

By now I don’t think anyone has filled that gap; there isn’t any social media built around networks that share and recommend their check-ins.

#GPSTracker already supports a lot of tracking, timeline and check-in features, synchronization of geo events with mobile devices, and even stats with arbitrary aggregations (by country, time range, city, region etc.). Plus some features that Foursquare never implemented (like searching for checkins on the timeline by simply selecting an area on the map).

#Microformats already support location tags through the h-adr class, although they are rarely used. Both #Webmentions and ActivityPub could send check-in activities as permalinks to pages with those tags. And the #OpenStreetMap APIs could do the heavylifting of retrieving POIs in in a certain lat/long box.

The only hurdle would be implementing the protocols under the hood, as both the Webmentions and Pubby libraries are in #Python while #GPSTracker is in #Typescript. But it could be a good chance to start writing multi-language bindings for those libraries.

Let me know if it’s something that you would use, or even self-host, and if you know if there’s anything in the Fediverse that already fills this niche.

Was mich an auch so stört: Die Illusion von Empowerment. »Schau, auch DU kannst programmieren! Hilf dir selbst!«

Nein, es ist kein Empowerment. Es ist eine Illusion, es ist das Gegenteil: Man lernt nichts, man wird abhängig. Man verlernt sogar eher sich selbst zu helfen.

자고로 미남미녀미논 기타 등등의 캐릭터는 당구를 한번쯤 해봐야 한다. 일단 보면 안다. "후우... 해볼까." 하는 긴장과 각오가 섞인 한숨소리를 내뱉은 후 길고 가느다란 당구대를 손끝에 잡고 예뻐보이는 얼굴을 약간 찡그려가며 목표를 조준하려는 그 진지함. 가슴이 풍만할 경우 허리를 굽히고 있을 동안 앞 셔츠 사이에 그 볼륨감이 살짝 보일 것이고 힙 라인은 또 예술인거임. 당구는 진짜 미인들이 하면 좋은 스포츠다. 그러니까 당구 좀 해줘. 당구 좀.
