This article introduces Logstash as an open‑source data‑pipeline tool, explains why it simplifies data ingestion, filtering and output, walks through installation and a first‑pipeline example, and provides a comprehensive overview of its input, filter, and output plugins with configuration snippets.
This article describes the two‑generation evolution of Youpai Image Manager's billion‑scale image search system, explaining the mathematical representation of images, the limitations of MD5, the first‑generation pHash‑ElasticSearch solution, and the second‑generation CNN‑Milvus approach for robust, large‑scale visual similarity search.
This article walks through the complete engineering workflow for building an image‑search system, covering CNN‑based feature extraction with VGG16, vector normalization, image preprocessing, black‑edge removal, and practical deployment of the Milvus vector database including hardware requirements, capacity planning, collection/partition design, and search result handling.
This article explains the fundamentals of building an image‑by‑image search system, covering image feature extraction methods such as hashing, traditional descriptors, CNN‑based vectors, and the use of vector search engines like Milvus for similarity retrieval.
This guide explains GitHub Actions, covering its core concepts, how to configure workflow files, define jobs and steps, use actions, set environment variables, apply conditional execution, and leverage matrix strategies for CI/CD automation across multiple platforms and runtimes.
This guide shows how to generate GitHub badges with shields.io, write unit tests using AVA, measure coverage with nyc, report results to Codecov, and automate the whole process with Travis CI, providing a complete CI/CD workflow for Node.js projects.
This article explains how to use Makefiles to create custom build commands, define variables, handle recursive targets, incorporate shell output, add conditional checks, and generate help messages, providing practical examples for Go projects and general build automation.
This tutorial walks through creating a lightweight Memcached client in Node.js, covering cluster routing with consistent hashing, low‑level TCP communication, a reusable connection‑pool implementation, and a custom protocol for get operations, complete with practical code examples.
To mitigate the inherent single‑point‑failure risk of the open‑source InfluxDB community edition, the article proposes deploying multiple InfluxDB instances with concurrent client writes, tracking failed writes, temporarily storing them, and using custom workers to replay data, while addressing timeout, data consistency, and storage considerations.
This article explains InfluxDB's Continuous Queries feature, covering configuration settings, basic and advanced syntax, execution timing, data range handling, result storage, and the use of RESAMPLE clauses with practical examples and code snippets.
