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.

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…… :blackcat_11128:

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":"w3.org/ns/activitystreams",
"name":"New Note",
"type":"Note",
"id":"critters.jpleite.eu/posts/1",
"attributedTo":"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."

@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.

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) :QueerCat_Lesbian: 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.

@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.

photo of a round sign with a blue background and a white drawing of a bicycle in a white circleA black & white New Yorker style single-panel comic, showing two women riding bicycles along a dedicated bicycle path (corrected signage) over a canal that is bordered by trees and walking paths beside buildings.

The woman in front is looking back toward the woman behind, and the caption says "If anyone proposed this in my town I'd kill them."

국내만 해도 수백만 MAU를 달성하는 서비스가 여럿이고, 엄청나게 많은 인원이 엄청나게 많은 가설을 세우면서 실험을 하고 있는데, 그 많은 실험이 기록으로 정리되지 않고 프로덕트의 피처로 환원되는게 좀 아쉽다. 실험이 누적되면 꽤 의미있는 인사이트를 얻을 수 있을 것 같은데.

At my previous full-time role I worked on a simulator for just these sorts of black start events. The US has come very close to having regional outages of this scale several times in the last decade, and our black start capability is largely untested to my knowledge (by which I mean largely untested in real-world scenarios).

Spain is about to face the challenge of a “black start”

"Open source AI models are more likely to recommend men than women for jobs, particularly the high-paying ones, a new study has found"

"We find that most models reproduce stereotypical gender associations and systematically recommend equally qualified women for lower-wage roles...These biases stem from entrenched gender patterns in the training data as well as from an agreeableness bias induced during the reinforcement learning from human feedback stage"

The fact that NWS field offices are not able to operate 24/7 anymore in growing number of locations, & that offices servicing major population centers no longer have supervisory meteorologists in charge, & that radar techs are becoming unavailable, is highly alarming.
