The article explains why process memory overflows are a critical issue in server operations and provides a step‑by‑step guide on using Linux cgroups to set precise memory limits, monitor usage, and avoid OOM crashes, illustrated with real‑world examples and troubleshooting tips.
The article analyzes the limitations of RTOS—such as weak file‑system support, constrained networking, and lack of process isolation—and explains why complex UI, multimedia, AI, and multi‑process requirements force developers to adopt embedded Linux, often in a hybrid architecture.
The article explains the design of Hermes' terminal UI gateway, detailing why the TUI does not import the Agent directly, how JSON‑RPC over stdio or WebSocket enables local and remote modes, and how slash commands are processed through a two‑layer routing system with a dedicated _SlashWorker subprocess and a pure‑function crash‑recovery plan.
The article explains why excessive conditional logic harms maintainability, introduces a flow‑engine and plugin‑extension architecture to isolate business code, demonstrates configuration and execution with Java examples from the open‑source MemberClub project, and lists the surrounding tech stack for practical learning.
This article describes the four-stage evolution of the Lego client‑side logging system—covering its initial zero‑to‑one architecture, the separation of business and technical logs, real‑time reporting improvements, and the latest architecture redesign that boosts performance, reduces overhead, and provides a safe migration path.
This article explains how isolating resources such as CPU, network, and disk through thread, process, cluster, and other techniques improves utilization, prevents cascading failures, and enhances stability in distributed backend architectures, illustrated with Netty, Dubbo, Tomcat, and Hystrix examples.
This article examines the importance of resource isolation in distributed systems, covering thread, process, cluster, data‑read/write, static, and crawler isolation, and illustrates practical implementations with Netty, Dubbo, Tomcat, and Hystrix, including code snippets and configuration tips.
This article explains how isolating resources such as threads, processes, clusters, and data centers improves efficiency, prevents cascading failures, and enhances fault tolerance in distributed backend systems, providing practical examples with Netty, Dubbo, Tomcat, and Hystrix.
The article explains the importance of isolating resources such as CPU, network, and disk in distributed architectures, describes thread, process, cluster, data‑read/write, static, and crawler isolation methods, and provides concrete code examples and best‑practice recommendations for backend developers.
The article explains why resource isolation is essential for distributed architectures, describes common isolation methods such as thread, process, cluster, data, static and crawler isolation, and provides concrete examples and code snippets for Netty, Dubbo, Tomcat, and Hystrix to illustrate practical implementations.
This article explains why resource isolation is essential in distributed architectures and details various isolation techniques—including thread, process, cluster, data‑read/write, static, and crawler isolation—illustrated with Netty, Dubbo, and Tomcat examples, code snippets, and practical recommendations.
This article explains the necessity of virtual memory in modern operating systems, covering its role as an abstraction layer, caching benefits, memory protection, multi‑level page tables, process isolation, and how these mechanisms improve performance, security, and resource utilization.
