LangChain is an innovative framework that is revolutionizing how we develop applications powered by language models. By introducing advanced principles, LangChain is redefining the limits of what traditional APIs can achieve. Moreover, LangChain applications feature intelligent agents, enabling lang...

Spring Session offers extensive customization options for Redis-backed HTTP sessions. This article explores key configuration aspects including serialization strategies, namespace management, repository selection, and event handling mechanisms. JSON Serialization Configuration By default, Spring Ses...
Counting Employees Meeting Target Hours This problem requires counting employees whose work hours meet or exceed a target value. A simple linear scan suffices. class Solution { public: int numberOfEmployeesWhoMetTarget(vector<int>& hours, int target) { int count = 0; for (int h : hours) {...

Inheritance and Class Hierarchies Inheritance is a fundamental pillar of Object-Oriented Programming (OOP) that allows a class (derived or child class) to acquire the members of another class (base or parent class), with the exception of private members. This mechanism promotes code reusability and...
Actor Model Overview ArkTS utilizes the Acter model for concurrent execution. In this architecture, computation is divided into independent actors. Each actor encapsulates its own state and behavior, communicating exclusively through asynchronous message passing. This isolation eliminates shared mem...
When Spring encounters a class with multiple constructors and needs to instantiate an object, it employs a sophisticated strategy to determine the most suitable constructor. This process is primarily handled by the autowireConstructor method within Spring's bean factory. The core logic of autowireCo...
Prometheus natively supports scraping metrics from services that expose a /metrics HTTP endpoint—typically in Prometheus exposition format. Etcd is one such service, exposnig its telemetry over HTTPS on port 2379. Integrating it into a Kubernetes-based Prometheus stack (e.g., using the Prometheus Op...
Self-QA Technology Overview Motivation for Self-QA Implementation The need for generating question-answer pairs stems from training large language models using business-related problems, materials, and documents. Previously, we extracted QA pairs by segmenting and tokenizing structured texts like en...
