    Sam Newman 谈构建弹性系统:微服务是最后手段

    《Building Microservices》作者 Sam Newman 在 Pragmatic Engineer 播客中称微服务是架构的"最后手段",并给出分布式系统三条规则:信息传输需要时间、资源可能离线、资源并非无限,其中资源耗尽导致的故障最多。他还谈到幂等性的两种实现方式——幂等键(idempotency keys)与指纹(fingerprints),以及 AI 如何改变软件开发,带来认知债务与认知投降等问题。

    什么是 Codemode:Armin Ronacher 谈 Pi 1.0 的 MCP 支持

    Armin Ronacher 撰文解释 Pi 1.0 新增的 Codemode:它让 LLM 在 harness 侧用 JavaScript 编排工具调用,而非把自定义工具塞进上下文。Codemode 运行在 QuickJS 的 WASM 沙箱中,无网络、无文件系统、无定时器且内存受限,只能通过调用更多工具与外界交互。它默认仅在启用 MCP 时开启,也可在设置中用 "defaultTools": ["+codemode"] 打开。

    ut rather than making a bespoke tool available, Codemode just allows the agent to reach into the AI SDK and invoke those directly. Here you can see how Jev is used to mass process GitHub issues for a quick sentiment analysis: Note how in that above example we also call store() which dumps the result of that execution into the session transcript. A future invocation of Codemode can thus read back that result if it wants to. The Promise.all here is fine, because Pi limits the total number of concu
