When AI Starts to Act, Security Issues Arise I recently attended a lecture on AI security, presented by Dawn Song from Berkeley. I found it quite enlightening; I used to think of AI as just a chatting tool, but now I realize that once AI is tasked with real actions, the security issues become significantly … Read more
Introduction When you open the Rust standard library documentation to view the definition of <span>Vec<T></span>, have you noticed that mysterious line <span>{ /* private fields */ }</span>? As Rust developers, we use Vec every day, but what exactly is hidden inside? Today, let’s dive deep into the source code of the Rust standard library, peeling … Read more
The standard library type vector represents a collection of objects, all of the same type. Each object in the collection has a corresponding index, which is used to access the object. Because vector contains other objects, it is also referred to as a container. 1.<span>vector</span> Basics 1.1 <span>vector</span> Overview: Core Features <span>vector</span> (commonly translated as … Read more
Today we begin learning about the main feature of C++, the STL. In fact, some readers have previously asked me when I would write about STL. However, since I am learning C++ while writing for this public account, I am not a C++ veteran. I can only organize and document what I have learned to … Read more
std::vector is one of the most commonly used data structures in C++. Compared to regular arrays/std::array, it supports dynamic capacity expansion, making it more flexible. Unlike raw pointers that require manual memory management, it automatically manages memory. It is contiguous in memory, supporting O(1) time complexity for random access. It seamlessly integrates with algorithms in … Read more
1. Core Differences: Memory Structure Determines Performance CharacteristicsVector uses a contiguous memory layout, with elements arranged neatly like soldiers, supporting O(1) complexity for random access, but insertion and deletion require moving subsequent elements. List, on the other hand, resembles a pearl necklace, with each node connected by pointers, supporting O(1) complexity for insertion and deletion … Read more
Part01 Exploitation Trend Escalation Recent monitoring by global cybersecurity teams has detected a significant increase in activities where attackers exploit vulnerabilities in Windows and Linux systems to conduct complex attacks aimed at gaining unauthorized system access. These attacks typically begin with phishing emails or malicious web content, deploying weaponized documents to initiate the attack. When … Read more
list (Doubly Linked List) <span>list</span> is a doubly linked list where elements are connected through pointers and does not support random access.Features: Elements are not contiguous in memory High efficiency for insertion/deletion at any position (O(1)) No support for random access (no [] operator) Additional storage for pointer information, resulting in higher memory overhead Defining … Read more
