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.

외국어 해석/해설은 제미나이가 잘 하고, 사진 크리틱이나 추천은 chatgpt가 잘 한다. 후자는 환각과 어우려져서 번지르르 문장만 좋은 건가 싶기도 하지만 건지는 것도 있으니까. 🤣😇

English speakers of the fedi. In a software with the interface in English, Reading a menu with verbs such as Save, Open, Close, Edit, Format etc., do you read them as imperative (an order: "do this") or as an infinitive (the "base form" of the verb, like "to do this")?

Are you a native speaker or have English as a second language?

@: 러시아가 미군 기지 정보를 제공했는데 제재를 왜 해제하냐는 말에 위트코프는 트럼프가 러시아(푸틴)한테 물어봤는데 자기들은 안했다고 한다. 우리는 그들의 말을 믿는다. 라고 답변해 논란

근데 요새 소프트웨어 기업들 주가 떨어지는것 보면 좀 웃픔 사실 AGI가 점점 가까워지니 소프트웨어 개발 비용이 크게 하락하는것 같으니 역설적으로 그동안 각종 테크 기업들이 만든 해자 자체가 무너지는 현상이 발생하고 있으므로... 어찌보면 업보빔 맞고 스스로 무너지는 느낌;; 즉 앞으로는 모델을 스스로 개발하고 변경 및 운영가능한 회사와 그렇지 못한 회사로 나뉠것 같습니다 전자가 돈을 쓸어담겠지 싶고... 후자는 망하거나 완전 레드오션일듯.

나도 어제 저 생각했는데 이미 언어모델 요새 나오는거보면 AGI(?)에 도달해있지만 메모리 구조의 한계와 업데이트가 힘든 관계로 제한적으로 쓰인다고 생각함 그리고 이런 문제가 해결되면 아마 직업이 슬그머니 사라지긴할텐데 아직은 아니고요... 다만 10년내에는 되지 않을까 예상해봅니다.

“Our work demonstrates that 𝑃ℎ𝑜𝑡𝑜𝐷𝑁𝐴 is unreliable for the detection of illicit content: it is easy to incriminate someone by sending them false content with a hash value close to illicit content (a false positive) and to avoid detection of illicit content with minimal modifications to an image (a false negative)”

White-Box Attacks on PhotoDNA Perceptual Hash Function

𝑃ℎ𝑜𝑡𝑜𝐷𝑁𝐴 is a widely deployed perceptual hash function used for the detection of illicit content such as Child Sexual Abuse Material (CSAM). This paper presents the first mathematical description of 𝐴𝑙𝑙𝑒𝑔𝑒𝑑 𝑃ℎ𝑜𝑡𝑜𝐷𝑁𝐴, a new function which has identical outputs to that of 𝑃ℎ𝑜𝑡𝑜𝐷𝑁𝐴 for a large database of test images. From this description, several design weaknesses are identified: the algorithm is piece-wise linear and differentiable, the hash value only depends on the sum of the RGB values of each pixel, and it is trivial to find images with hash value equal to all zeroes. The paper further demonstrates that gradient-based optimization techniques and quadratic programming can exploit the mathematical weaknesses of 𝐴𝑙𝑙𝑒𝑔𝑒𝑑 𝑃ℎ𝑜𝑡𝑜𝐷𝑁𝐴 and 𝑃ℎ𝑜𝑡𝑜𝐷𝑁𝐴 to produce visually appealing exact collisions and second preimages; for near-collisions and near-second-preimages the image quality can be further improved. The same techniques can be used to recover the rough shapes of an image from its hash value, disproving the claim from the designer that 𝑃ℎ𝑜𝑡𝑜𝐷𝑁𝐴 is irreversible. Finally, it is also shown that it is easy to produce high-quality perceptually identical images with a hash value that is far from the original image allowing to avoid detection. We have implemented our attacks on a large set of varied images and we have tested them on both 𝐴𝑙𝑙𝑒𝑔𝑒𝑑 𝑃ℎ𝑜𝑡𝑜𝐷𝑁𝐴 and 𝑃ℎ𝑜𝑡𝑜𝐷𝑁𝐴. Our attacks have success rates close or equal to 100% and run in seconds or minutes on a personal laptop; they present a substantial improvement over earlier work that requires hours on parallel machines and that results only in near-collisions. We believe that with additional optimization of the parameters, the image quality and/or the attack performance can be further improved. Our work demonstrates that 𝑃ℎ𝑜𝑡𝑜𝐷𝑁𝐴 is unreliable for the detection of illicit content: it is easy to incriminate someone by sending them false content with a hash value close to illicit content (a false positive) and to avoid detection of illicit content with minimal modifications to an image (a false negative). False positives and leakage of information are particularly problematic in a Client Side Scanning (CSS) scenario as envisaged by several countries, where large hash databases would be stored on every user device and billions of images would be hashed with 𝑃ℎ𝑜𝑡𝑜𝐷𝑁𝐴 every day. Overall, our research cast serious doubts on the suitability of 𝑃ℎ𝑜𝑡𝑜𝐷𝑁𝐴for the large-scale detection of illicit content.

🤘 New episode of Changelog News!

This week's been wild — Iran bombed AWS data centers to take down Claude, OpenAI dropped GPT-5.4 (and it's seriously good for coding), and living brain cells are literally playing DOOM. We've also got a heartfelt take on what it feels like to be a 10x engineer in the age of AI, plus some cool new tools like Handy for speech-to-text and web haptics. Oh, and new MacBook Pros with M5 Pro and M5 Max are up for pre-o...

그러니까 민주당을 "온건좌파"로 보고. 그래서 한국의 게임 개발자는 민주당 지지자가 많으니 좌파적이다... 라는 이야기 읽는 중

일본 탐라에 블루아카가 한국 좌파적인 작품이라는 의견들이 있다고 해서 굳ㄱ이 ㅋㅋㅋ 또 그걸 찾아봤습니다. 몇 년 된 걸 보니 의외로 종종 나오는 이야기인가 봐요. 일본 남성 게이머 기준으론 작중에서 소재나 이야기 흐름 자체가 한국 정치사회가 반영된 것 아니냐던가, 꽤 진보적이거나 또는 급진적ㅋㅋㅋ으로 느껴지는 부분이 있다고. 전공투와 소녀혁명 우테나의 나라에서 도대체 뭔 소릴 하는걸까...

처음부터 "이란의 미사일 기술이 고도화 되고 있고, 드론은 대량 생산되어 우크라이나 전쟁에서 사용되고 있다." 라고 말하고 그것만 했으면 면피라도 가능하지, 이란 최고지도자를 죽여버리고 "우리의 공습에는 레짐 체인지를 할 의도가 없었다." 라고 말하면 그게 말입니까 방구입니까.
