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.

RE: mastodon.online/@mastodonmigra

Oh boy, here we go again. The claims in this thread have been debunked a *lot*.

Yes, if you want to run a full-network appview as Bluesky scale, then that means you're run a social platform for 42 million users, processing billions of events.

HOWEVER, there are smart was to scale down what the Bluesky AppView does, to smaller scales which make sense for your community.

A fantastic example of this is RedDwarf, which skips all the relays, and interacts directly with PDSes. That does come with some trade-offs, but shows that you can do things at a different scale with different trade-offs.

All ActivityPub servers *can* rely on expensive network resources: hosting an entire copy of the Mastodon networks' data for a large instance is complicated, as is storage a copy of (in a cache) of all the posts and media attachments. (for instance, mstdn.ca said today that their database is 450GB, and they're the 53 most active server on the network).

It's been a long pain point that operating Mastodon requires storing a copy of all remote media attachments, which has lead to proposals for shared media infrastructure. Having to provide CDN infrastructure for all that media is also really expensive.

Scaling compute to handle sudden influxes of activity, especially in mastodon, often means significantly over provisioning infrastructure. It's not super easy to auto-scale sidekiq workers (possible, but requires engineering).

Depending on who's on your server, you can also have some truly horrifically expensive write paths: one post published by Mastodon Migration *could* result in up to 34,000 outbound HTTP requests. Sure we have sharedInbox that can get that number down to unique shared inboxes across all a users' followers. This is even called out in the spec: w3.org/TR/activitypub/#shared-

So does Mastodon scale up? If Bluesky doesn't scale down, we can certainly ask the same questions of Mastodon in the inverse direction.

I don't know about Mastodon Migration, but I've been on the infrastructure team for a large mastodon server (Hachyderm), and the amount of stuff we needed to do to ensure up time and low response times, and quick processing of inbound activities was a *lot*.

メタプログラミングって言い方は大仰で、要は問題領域の事象を記述するのに都合のいい語彙や文法を定義して、そのDSLを使えば解決しやすく便利ってことなので、それはエンジニアリング手法として、物理や数学はもちろん哲学や法学でもやっていることだと思うのよな。

Private equity only bought into housing as a growth asset because (1) we stopped building housing where jobs are and (2) your parents shacked their retirement to house prices going to the moon. The best way to get PE out of housing is to build a shit ton of housing so it becomes uninteresting.

周一(23日)上午11時許,警方接獲位於旺角彌敦道673號的滙豐銀行職員報案,指一名男子懷疑在櫃檯企圖存入一張面值1億港元的懷疑偽鈔,職員察覺有異後報警求助。

警員接報趕至現場,於該名57歲、姓陳、持雙程證的內地男子身上,檢獲該張1億元懷疑偽鈔。進一步搜查時,人員再發現一張面值5億元的假鈔,以及兩張面值100萬元的所謂「回歸紀念鈔」。據了解,涉案偽鈔當中包括標示為「債券」的假紙幣。

陳男涉嫌「行使偽製紙幣」及「管有偽製紙幣」兩項罪名被捕,現正被扣留調查。案件交由旺角警區刑事調查隊第二隊跟進。

테슬라 FSD에 대해서 일부 사람들이 하는 말이 “나 운전 잘 못 하니까 FSD가 해주면 짱이겠다”인데, 사실 굉장히 위험한 생각이다. 그만큼 FSD 시스템이 예상치 못한 행동을 할 때 대처가 훨씬 미흡할 것이라는 뜻이기 때문. 반응 속도도 느릴 것이고, 대처 방식도 문제일 것이고.

운전 미흡한 분이 자율주행에 차를 믿고 맡길 수 있는 건 최소 레벨 3은 되어야 하지 않을까. (FSD는 레벨 2임)

아. 연합보다 매일하고 천지일보가 더 먼저 올렸네요. 전한길, 김현태를 가장 먼저 취재하는 매체라는게 의미하는게 뭐겠어요. 진짜 한심해서 참을 수가 없다...

Steve Klabnik also had an interview on lobste.rs. There's a lot in it! It's a cool read! alexalejandre.com/programming/

And then it gets to the AI part and he's just like "oh I don't write code anymore".

And notably Steve Klabnik has a lot to say about code, but it's *all in the past*.

Lots of brilliant people are becoming non-practitioners.

@cwebberChristine Lemmer-Webber What's telling, I think, is that all these people go on about how much they're doing and how great AI is to help them build more *but there's no actual demonstrable stuff being done.* I mean, if AI was some kind of Nx multiplier you'd think we'd be getting N times more actual functionality out of software but mostly it seems like the N multiplier only applies to blog posts about how AI multiplies their programming.
