New preprint: AI_Bleeding — inference cost amplification via OOD linguistic payload

TL;DR: send queries in Grecanico or Farsi to an LLM endpoint → TTFT +59.8%, compute cost +2.8%, statistically significant. No vuln, no volumetric signature, evades all standard detection.

Worst case: exposed unauthenticated Ollama instance with num_predict=4096 + keep_alive=300s → Amplification Factor 17.56 Wh/KB. 3KB of attacker bandwidth → enough energy to charge a phone 5%.

Especially nasty for:
- PA/judicial chatbots on fixed budgets
- Pay-per-use API deployments with client-side exposed keys
- PNRR-funded public sector AI with zero inference monitoring

Four scenarios: EDoS, browser JS distribution, Ollama open-proxy relay, frontier providers as involuntary relays.

All tests on self-hosted Ollama, no commercial endpoints touched.

The Big OOPs: Anatomy of a Thirty-five-year Mistake

Casey Muratori – The Big OOPs: Anatomy of a Thirty-five-year Mistake – BSC 2025

This is a fantastic deep-dive into the history of object-oriented programming with 50+ years of primary sources! Even though I make information systems, not games, I really enjoyed Casey Muratori’s talk.

In meinem Blog geht es ja hauptsächlich um Java-Themen sowie begleitendes Material. Hier möchte ich einmal über eine häufig auftretende Frage sprechen: Wie kommt man von der objektorientierten Analyse zur objektorientierten Programmierung?

Việc sao chép đối tượng trong Java có thể được thực hiện hiệu quả bằng Mẫu Thiết Kế Hình Mẫu (Prototype). Bài viết này giải thích rõ ràng về Mẫu Hình Mẫu, phân biệt Shallow vs Deep Copy, ví dụ mã Java 21 hiện đại (không vòng vo Cloneable), sơ đồ UML & Sequence, cùng các câu hỏi phỏng vấn thường gặp. Phù hợp cho người học OOD/OOP & chuẩn bị phỏng vấn Java. #Java #DesignPattern #LậpTrình #OOD
