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.

컴퓨터공학과 취업률이 하락세인데도

한국의 오픈소스에 불이 붙지 않는게 의아함.

러시아, 우크라이나, 중국 애들이 왜 오픈소스 열심히 하는 줄 암?

미국과 이런저런 이유로 등을 지는 국가들로서, 미국의 견제라는 큰 장벽까지 넘어서는 수단이 오픈소스이기 때문임.

우리나라는 뭐가 잘나서 안함?

One thing I love about being involved in my College is I get a direct line on what young people are thinking.

In my circle of 30-50-somethings, it's taken for granted that "AI" is changing everything. Some people express caution that we shouldn't even take any position on software engineering education because it will be out of date within a week.

Meanwhile, my students are telling me that in their cohort, everyone is tired of AI and wants to learn proper software engineering.

One lesson here is: do you remember how clueless your boss was about everything? Recognise when you are in the "boss" demographic, and that your breathless enthusiasm and concern may be equally misinformed.

minor tr(1) gotcha I encountered recently: It does NOT use regex-style "[a-z]" notation for a character class. One might do something like

$ echo 'abcd123' | tr -d '[a-c]'
d123

which does what's expected. But then put a "[" or "]" in the input:

$ echo '[abcd123]' | tr -d '[a-c]'
d123

The "[" and "]" are treated as literal characters and get deleted/translated too. You can use class-names with them though:

$ echo '[abcd123]' | tr -d '[:alpha:]'
[123]

랩 혹은 파일럿 단계에서는 즉각적인 수리 및 개조(+디지털 노이즈 배제)가 가능하도록 바로 아날로그 부품 갖다 꽂고 거의 패키징을 안하는데 모든 기계를 상용화<한다고 하면 일반인들이 부품을 잘 건들 수 없움+오염에 강하도록 아예 다 막아버리는게 기술적으로도 편햐긴혀 저도 장치개발하는 사람이라...메카조형적인 부분이 밖으로 전혀 드러나지 않고 유저인터페이스만 갖춰진 디자인을 좋은 디자인이라고 보는게 요즘 트렌드라 생각함요(메론머스크의 테슬라) 이제 연구소에서 디자인은 매끈하게하고 그림그릴땐 반대로 개번잡하게 그림 쩔수업다 취향이다

I've always wanted better tools to read and navigate—not edit!—source code.

For example, it's incredible to me that there is no iPad app that does LSP features plus bookmarks, navigation tree, etc.

Maybe now that LLMs made it more people's job to read code, we'll get good code reading tools?

Loops.Video could be the ’s breakout moment because is where habits already live.

If it matches the swipe-speed joy of mainstream apps while keeping open follows, portable identity, and community moderation, get reach without lock-in.

One viral template or creator wave can turn from concept into daily routine: and that’s how ecosystems tip.

key: frictionless onboarding, fast discovery, and easy cross-posting to other servers.

"Broadcasters do not operate in a vacuum; they operate inside regulatory environments, political climates and corporate risk calculations. When presidents and their allies openly threaten or target networks, it is naive to pretend that has no downstream effect on editorial choices – especially in high-stakes live broadcasts tied to billion-dollar rights deals.

"But there is a difference between contextual pressure and visible reality distortion. When global audiences can compare feeds in real time, the latter begins to resemble something else entirely: not editorial judgment, but narrative management. Which is why comparisons to Soviet-style state-controlled broadcasting models – once breathless rhetorical exaggerations – are starting to feel less hyperbolic."

選挙結果の如何を問わず、私は私なりに平和を希求し続けるのみ。やれ少数派だ負け組だと、笑いたければ笑えばいい。そんなことで私の「信」は揺るがないから。

This experiment (authored by several well-known mathematicians) revives an archaic practice (last seen in the era of Gauss) of posting encrypted proofs before revealing them: arxiv.org/abs/2602.05192 . Here, the challenge is to see whether 10 research-level problems (that arose in the course of the authors research) are amenable to modern AI tools within a fixed time period (until Feb 13).

The problems appear to be out of reach of current "one-shot" AI prompts, but were solved by human domain experts, and would presumably a fair fraction would also be solvable by other domain experts equipped with AI tools. They are technical enough that a non-domain-expert would struggle to verify any AI-generated output on these problems, so it seems quite challenging to me to have such a non-expert solve any of these problems, but one could always be surprised. It will be interesting to see if there were any notable outcomes to this experiment by the expiration of the time linit.

古董 上电后毫无反应。我准备好万用表、示波器准备到处戳一戳,抓抓波形,结果发现是 DC 连接器 GND 焊盘铜箔断裂,10 秒飞线解决(搭接到了旁边的手柄接口焊盘,两者共用 copper pour)。但是这个手边仅有的古董黑白电视不能正常 VSYNC,只能看出有一个“小霸王”商标。这说明 CPU/PPU 能运行了,估计已经修好了,等待采集卡到来再试。

I've been participating in online discussions for a long time, but I'm still not able to understand people that receive constructive replies to their posts and just leave them on read...

I'm unable to do that myself. I feel I owe the person that took time of their day to say something to me to acknowledge their reply somehow. Either as a like, or a "thanx", or anything but silence...

Saying something constructive to someone and receiving no reaction back from them is quite unpleasant to me. :)

PS. This is not targeted any anyone here. This happens a lot in other fora.
