Backend tech guide and AI engineering practice covering fundamentals, databases, distributed systems, high concurrency, system design, plus AI agents and large-model engineering.
RustFS, a Rust-written S3-compatible distributed object storage, hits GA with 32.5K GitHub stars, offering MinIO migration paths including on-demand data migration, versioning, erasure coding, and storage pool scaling, plus a Docker quick-start for production evaluation.
The author empirically tests viral claims that OpenAI secretly degrades Codex for relay accounts, analyzing two benchmark tasks — a candy probability puzzle and an SVG pelican animation — finding local Codex passes both, while clarifying OpenAI's documented temporary downgrades target suspicious login activity, not relay usage specifically.
The article reviews OpenAI's new guide for GPT-6 Astra, showing how to narrow Skill trigger conditions, use progressive disclosure in SKILL.md, make AGENTS.md document reads task-specific, and clarify completion criteria; the author demonstrates a practical audit of their interview-guide project where Codex caught a rate-limiting documentation mismatch.
OpenHands provides a self‑hosted Agent Canvas that consolidates multiple AI coding agents such as Codex, Claude Code, Gemini CLI and DeepSeek Harness into a single web UI, supporting customizable backends, automation via GitHub and Slack, and extensible MCP/Skills for seamless development workflows.
The article recounts a massive GitHub outage, then details Cursor's early‑beta Origin platform—its features, GitHub‑mirroring workflow, integration with Cloud Agent and Automations, performance claims, current limitations, and practical guidance for developers considering a switch.
The article explains how developers can leverage AI coding agents to accelerate routine tasks while still needing human oversight for requirement clarification, verification, and risk management, and offers concrete interview advice on framing this reality to hiring managers.
DeepSeek V4‑Pro‑0813 and Grok 4.6 were released simultaneously, with Grok achieving a 65.9% DeepSWE score and low $2/$6 API pricing, while DeepSeek’s V4‑Pro scores 62.7% on DeepSWE, adds a Responses API for Codex, and hints at an upcoming Harness internal test.
The article explains why, with stronger models like GPT‑5.6, many traditional coding Skills become redundant, outlines the progressive‑disclosure mechanism, highlights token and security costs, and provides concrete criteria and examples for deciding which Skills to retain or discard.
OpenHands is a self‑hosted coding‑agent console that lets multiple agents run across local machines, Docker, VMs or the cloud, integrates Claude Code, Codex and Gemini via ACP, supports automated workflows, and includes detailed installation and security guidance for safe long‑term use.
After Kimi K3’s official launch, the author evaluates its 2.8 T‑parameter, 1 M‑context, multimodal coding agent across three real‑world scenarios—a full‑stack hotspot‑tracking MVP, a Java project refactor fixing stock‑search encoding, and a 3A‑style game demo—detailing setup, performance, and limitations.
