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.

돈 좀 버니까 다이소에서 천원 주고 한두달 쓰다 망가져서 버리고 새로 사는 짓 좀 그만 두고 비싸더라도 제대로 만든 제품으로 사서 반영구적 못해도 몇 년 단위로 쓰고 싶음 혹시 이런 제품들 좀 추천해주실 수 있으실까요? 정말 별거 아닌 제품이라도 괜찮습니다 샤워타올 케이블 등등...

Some posts about Mozilla employees and AI are being widely reshared around fedi today. Metaphors of bodily autonomy and consent are being applied to whether Mozilla puts AI in their products

I’ve worked on products with extremely passionate early communities for decades now and this kind of interaction always makes me sad.

Some people make your software part of their identity and you will never please them. But more broadly we have no institutional structure for software that users can trust

What about non-profits?

My partner works in non-profits, and always emphasizes, they are designed to be controlled by their funders. Not the people they serve.

It’s a form designed for tax sheltering, for social control, for wielding influence, for indoctrination, for giving spouses of the elite something to do without meaningful power

If you have radical beliefs in your mission statement you’re merely hoping your board is extremely tolerant of undermining their own power

i was a bit curious about the actual transfer size impact of json-ld, and what would happen if you replaced json-ld with simply explicitly repeating the namespaces. so i threw a few payloads, both compacted and expanded, into lynn.github.io/flateview/ at gzip level 6

my actor, compacted - 1855 bytes gzip'd
my actor, expanded - 1877 bytes gzip'd
my actor, compacted with no context - 1793 bytes gzip'd

quoted post, compacted - 2024 bytes gzip'd
quoted post, expanded - 2033 bytes gzip'd
quoted post, compacted with no context - 1985 bytes gzip'd

mastodon.social instance actor, compacted - 2761 bytes gzip'd
mastodon.social instance actor, compacted, with unused context values removed - 644 bytes gzip'd
mastodon.social instance actor, expanded - 707 bytes gzip'd
mastodon.social instance actor, compacted, with no context - 667 bytes gzip'd

new from me: FR#152 - The DSA Needs Big Tech

The panel at FOSDEM with @alexandrageese and @mellifluousboxFelix Hlatky about the DSA and the fediverse showed a deep structural tension: the DSA's power depends on Big Tech platforms existing, and the fediverse is a network specifically designed they won't

I have deeply mixed feelings about 's adoption of JSON-LD, as someone who's spent way too long dealing with it while building .

Part of me wishes it had never happened. A lot of developers jump into ActivityPub development without really understanding JSON-LD, and honestly, can you blame them? The result is a growing number of implementations producing technically invalid JSON-LD. It works, sort of, because everyone's just pattern-matching against what Mastodon does, but it's not correct. And even developers who do take the time to understand JSON-LD often end up hardcoding their documents anyway, because proper JSON-LD processor libraries simply don't exist for many languages. No safety net, no validation, just vibes and hoping you got the @context right. Naturally, mistakes creep in.

But then the other part of me thinks: well, we're stuck with JSON-LD now. There's no going back. So wouldn't it be nice if people actually used it properly? Process the documents, normalize them, do the compaction and expansion dance the way the spec intended. That's what Fedify does.

Here's the part that really gets to me, though. Because Fedify actually processes JSON-LD correctly, it's more likely to break when talking to implementations that produce malformed documents. From the end user's perspective, Fedify looks like the fragile one. “Why can't I follow this person?” Well, because their server is emitting garbage JSON-LD that happens to work with implementations that just treat it as a regular JSON blob. Every time I get one of these bug reports, I feel a certain injustice. Like being the only person in the group project who actually read the assignment.

To be fair, there are real practical reasons why most people don't bother with proper JSON-LD processing. Implementing a full processor is genuinely a lot of work. It leans on the entire Linked Data stack, which is bigger than most people expect going in. And the performance cost isn't trivial either. Fedify uses some tricks to keep things fast, and I'll be honest, that code isn't my proudest work.

Anyway, none of this is going anywhere. Just me grumbling into the void. If you're building an ActivityPub implementation, maybe consider using a JSON-LD processor if one's available for your language. And if you're not going to, at least test your output against implementations that do.

도서관 관련 아시는 분들께 여쭙습니다. 1) 희망도서신청 거부사유로 ‘정치적’인 경우가 무엇을 말하는지 알고 싶습니다. 2) 현역시장의 도서들이 지방선거를 앞두고 지역도서관에 들어온 경우 이른바 어른의 사정이 있겠지만 문제 없는지요? 시장의 도서기증이어도, 도서관에서 돈주고 샀어도, 누군가의 희망도서신청이었어도 정치적인 것 같습니다만. 지역 도서관에 문제 제기하기 전에 관련 정보들을 알고 싶습니다.

井関源二 中野区議会議員 れいわ新選組 (@isekigenji) on X
漫画家やアニメーターや声優の方々が一斉に政治的発言をしてくれるのはありがたいし、嬉しいんだけど、山本直樹さんや新井英樹さん並みに普段からして欲しいなぁ。

政治的発言が普通になれば、そんな勇気もいらなくなるよ。 x.com/i/status/202035965745865
自民党勝利良かった!って言ってるクリエイターの人いたし、その人インボイスについても言ってた気がするね
