Sharing practical vivo Internet technology insights and salon events, plus the latest industry news and hot conferences.
This guide walks Android developers through the concepts, tools, and step‑by‑step code needed to render video frames with OpenGL ES, apply custom shaders, and optionally build a custom FFmpeg‑based player for advanced animation effects.
This article explains the evolution of Vivo's real‑time recommendation feature‑concatenation architecture, compares hour‑level, Redis‑streaming and RocksDB state‑backend solutions, and details the memory, performance, startup and HDFS RPC problems encountered along with the concrete fixes applied.
The 20th China Linux Kernel Developers Conference, hosted by vivo, presented eleven technical talks covering AI‑driven kernel challenges, memory‑compression techniques, heterogeneous compression, async file‑cache management, uncached I/O, direct I/O for compressed files, parallel writeback, host‑initiated defragmentation, zoned storage, energy‑efficient I/O, and eBPF‑based CPU idle policies, each with concrete performance results and implementation details.
This tutorial walks you through the entire process of creating a browser‑based AI version of the classic "draw‑and‑guess" game, covering model selection, dataset preparation, CNN training with TensorFlow.js, model integration into a Vue front‑end, performance optimizations, and deployment steps.
This article analyzes a production incident where Redis failed to retrieve keys at 2 AM, tracing the root cause to a short‑term memory write‑full condition caused by massive GET request bursts that overflowed client output buffers, and outlines both emergency fixes and long‑term mitigations.
The 2025 Vivo Developer Conference showcased cutting‑edge advances in traffic‑driven growth, microservice and Dubbo performance tuning, full‑link multi‑version environment automation, and GPU‑container AI training platforms, highlighting how these innovations boost efficiency, reliability, and cost‑effectiveness across Vivo’s internet services.
This article details how Vivo Browser's welfare center was re‑engineered—splitting services, sharding databases, adding arbitration and soft‑transaction mechanisms—to overcome traffic, I/O, and data‑consistency challenges, enabling stable operation at tens of millions of daily active users while reducing storage costs.
This article compares Three.js and Galacean Web 3D engines, explains performance bottlenecks of Three.js, showcases Galacean's core advantages, and provides a step‑by‑step migration guide with code examples for initializing, loading models, replacing assets, and handling animations.
This article presents a training‑free, architecture‑agnostic method that leverages LaTeX‑style structured inputs to preserve document hierarchy and spatial relationships, thereby improving multimodal large language model performance on document question answering tasks across multiple benchmarks.
In an interview, Vivo’s BlueOS team explains why they built their operating system with Rust, detailing the language’s safety and performance benefits, the challenges of adoption, the measurable gains in reliability and maintenance, and the learning curve developers faced.
