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.

Someone brought up the issue of running out of space on btrfs and not being able to delete stuff. There are posts about this from years ago, but I wanted to see if it's still a problem.

The answer is... kind of, if you try hard enough and do absolutely unhinged things. I had to create a snapshot of a tiny (4GB) but full (data + metadata) filesystem with hundreds of thousands of files (with data, with xattrs, and empty to fill everything up) and then delete files without deleting the snapshot, retrying when I got an error and sync()ing the filesystem every time. At one point I managed to make the FS go read-only, and then remounting again and trying more torture in parallel shells eventually got it wedged into a state where it couldn't mount R/W at all (cannot do orphan cleanup due to -ENOSPC).

Even then, the FS was still mountable R/O (so all the data was recoverable). And even then, I found a way out: although you can't add a device to a FS that isn't mounted R/W, you can expand the base device with btrfs filesystem resize --offline, and you can use dm to glue two devices together temporarily for this purpose. I was able to mount R/W then, delete stuff the "proper" way (snapshots first), shrink again, and completely fix the situation.

So yeah, I don't think this is really a problem any more, more specific bugs notwithstanding. You have to try really really hard to cause the issue and even then there's still a way out.

MS가 윈도를 구독 기반으로 이전하고 싶어한 건 꽤 오래 전이긴 한데, OEM도 있고 해서 추가하는 정도에 그칠 것.

오히려 길게 준비한 모듈러 윈도가 기대된다. 이건 진짜 10년은 넘게 준비한 플젝인데 드디어 릴리즈인가.

난 내 자캐가 5명 정도 있어도 "와 많다" 라고 생각하면서 배부른데
이미 자캐가 100명 넘는 사람들은 어떻게 감당하는거지...
난... 다 챙겨주지 못할 것 같아 미아내 얘들아

It’s great to see Microsoft trying so hard to make this year the year of Linux on the desktop

Edit: article was retracted, so it seems we will have to wait to see what horrors Microsoft has in store ☺️

@ada I mean… hardly love. More like a one-week crush after which I found out that I was barking up the wrong tree and moved on. We were just friends after that and that’s fine. It’s just weird to find out that it wasn’t the wrong tree after all 🤷‍♀️

Czy Twoje teksty pisane przez AI brzmią jak... AI? 🤖

Samo "wypluwanie" treści to za mało. Prawdziwa moc drzemie w strategii. Na moim szkoleniu "AI Copywriting" uczę, jak połączyć klasyczne modele (AIDA, PAS, BAB) z najnowszymi modelami językowymi.

Piszesz szybciej, ale przede wszystkim – skuteczniej. Budujesz markę, która sprzedaje, a nie tylko wypełnia feed.

最近CWT場次有噁男用紙條讀心術(Billet technic)去強迫要別人女生的電話的fb投訴,本來以為是動漫圈裡面哪個不檢點的男生騷擾,但是好死不死這件事就是被身為魔術師的我看到:

1、一般正常的魔術表演者都會事前告知「僅限表演用途使用」,並徵取觀眾同意,使用表演完之後也會將有記錄的個人資料當面銷毀或交給觀眾(包括在撲克牌上簽名的牌),會違反你觀眾意願的就有問題。

2、我根據匿名投訴推測,該位噁男使用的是最古典的紙條讀心術版本,該版本發明於1920年,故已進入公領域之公共財,為了讓各位學習戲法自娛娛人,也為了反制騷擾,我將釋出兩個版本:

a、Billet technic 1920 version :古典版本的表演法。

b、,我研究出這個版本是為了反制騷擾,如果對方真的是為了純粹表演的話,請手下留情。

3、根據投訴的對話內容應該是某個PUA 戀愛家教班,這剛好踩到我的地雷,,你死定了。

該電子報將於3/15釋出,請繼續關注。

Wchodzę od rana na Masto, a tu Windows 12 nadchodzi.

1. AI jako fundamentalna część systemu.
2. System modularny.
3. Wymóg posiadania w kompie specjalnego modułu NPU.
4. Zaawansowane opcje AI za subskrypcją.
5. Odświeżony wygląd.

Rozłóżmy to na czynniki pierwsze, bo mamy tu istny festiwal wszelkich zapalników do wielkiego wybuchu:

1. Widzieliśmy już jakość AI od Microsoftu. Nie jest kiepska - jest zła, najgorsza na rynku mimo tego, że ich CoPilot używa pod maską Chatu GPT. Skąd ta różnica w jakości? Ano powiem Wam skąd - MS oszczędza nie tylko na ludziach, ale też na AI obcinając sztucznie okienko kontekstowe Chatu GPT. To dzięki temu może oferować nadal AI za darmo ale też utrzymywać konkurencyjną cenę $10 za Github Copilota (który swoją drogą też jest najgorszy na rynku XD).
2. O tym to ja już słyszę od chyba jeszcze czasów Windowsa 8. Normalnie to bym się cieszył, ale znając ich partactwo to nie ma z czego.
3. Biorąc pod uwagę, że obecne modele lokalne nawet z modułem NPU działają raczej słabo i nadają się do niewielu sensownych zastosowań widzę w tym raczej coś pokroju modułu TPM - wymuszenie na ludziach by wymienili swoje sprzęty, a AI i tak będzie w 90% działać w chmurze.
4. Tego wszyscy powinniśmy się spodziewać, bo to jest naturalna kolej rzeczy. AI jest piekielnie drogie i ceny, które mamy do płacenia w tej chwili za subskrypcje narzędzi LLM są i tak niskie.
5. MS już kombinował ze zmienianiem wyglądu Windowsów (8, 8.1, 11) i zawsze kończyło się to wkurwieniem użytkowników. Najgorzej było z Windows 8, bo tam zdecydowano się na rewolucję, co jest niedopuszczalne w przypadku użytkowego UI, do którego przywykły miliardy użytkowników przez lata. Teraz niby zmiany mają być mniej rewolucyjne, ale wciąż będą wymagały zmiany przyzwyczajeń.

Odpływ użytkowników do Linuksa i macOS będzie trwał, a po premierze tego ustrojstwa pewnie przyspieszy.

android drama

@keepandroidopen@techhub.social

also you make it appear as the mentions of the "advanced flow" only appear on that random year old article, but in fact it is explicitly mentioned on the main FAQ and it also
EXPLICITLY states that installs through adb won't be affected at all.

...we plan to offer two paths for experienced users to install unverified apps:

Android Debug Bridge (ADB): Developers and power users can still use Android Debug Bridge (ADB) to build, test, and install modified or unverified apps on their own devices, which remains the standard method for development work.

Advanced flow: We are building a flow that allows experienced users to proceed with installing an unverified app after going through a series of clear warnings. This new mode is designed to resist social engineering, helping users fully understand the risks, but ultimately gives experienced users the choice to accept the heightened security risk and install the software. We are gathering early feedback on the design of this feature now and will share more details in the coming months.
this (again, very explicitly) covers both unverified and modified apps.

also there are couple moe exceptions:
Apps distributed through your organization’s store, on managed devices, won't need to complete the verification requirements
