With the increasing popularity of open-source products, it is crucial for a backend engineer to be able to clearly identify whether an abnormal machine has been compromised. Based on my personal work experience, I have compiled several common scenarios of machines being hacked for reference. This article is first
I read a paper about real-world go concurrency error bugs, and here’s a transcript of what I read as a start to learning about go concurrency programming.
In 2023, there have been some changes to Go’s concurrency library, and this article provides an overview of these changes. Minor details such as typos and documentation changes will not be covered.

一个提案，900 条评论，Go 核心团队亲自下场——这场争论终于要尘埃落定了吗？
Go Is Finally Getting Lambdas — 8 Years in the Making How a Single Proposal with 900+ Comments is Quietly Reshaping Go's Syntax It started in August 2017. A developer opened issue #21498 on the Go repository with a modest title: "proposal: spec: short function literals." Nobody

深入 Go 最常用包的 5 年重写之旅：API 完美主义、内存回退，以及向后兼容的沉重代价。
最近有人做了一个实验，我看完之后好几天都在想这件事。 他们让 Claude Code 去构建项目——SaaS 应用、API、数据管道——不给任何工具限制，就问：你觉得应该用什么？然后把 2430 次回答里的工具推荐都统计了一遍。 数字挺吓人的。 Vercel：JS 项目的部署推荐率 100%。不是 80%，不是 90%，是一百分之一百。Stripe 拿走了 91.4% 的支付集成推荐，shadcn/ui 拿走了 90.1% 的 UI 组件推荐，GitHub Actions 拿走了 93.8% 的 CI/CD 推荐。与此同时，AWS
Uber 重视可靠的数据湖（Data Lake），其分布在本地和云环境中。这种多区域架构在有限的网络带宽下为确保可靠且及时的数据访问带来了挑战，尤其是在灾难恢复场景中需要实现无缝的数据可用性。Uber 使用 Hive Sync 服务，该服务基于 Apache Hadoop® Distcp（Distributed Copy）进行数据复制。然而，随着 Uber 数据湖规模超过 350 PB，Distcp 的局限性逐渐显现。本文探讨了针对 Distcp 所做的优化，以提升其性能并满足 Uber 在分布式基础设施上日益增长的数据复制和灾难恢复需求。
最近，Go 语言社区围绕一个全新的内存管理提案展开了激烈讨论：在不依赖垃圾回收 (GC) 的情况下直接释放并重用内存。#74299 引入了 runtime.free 及相关机制，试图让编译器和标准库在特定场景下安全地跳过 GC，对短命的内存对象进行即时回收利用github.comgo.googlesource.com。此举被认为可能为 Go 带来一次性能上的革命：初步原型显示，在 strings.Builder 这样的场景中，利用该机制性能提升可达 2 倍github.com。本文将回顾 Go 内存管理领域从 arena 实验到 memory region 构想，再到 runtime.free 提案的探索之旅，并剖析这一新提案的技术细节、产生的意义、演化过程，以及对普通开发者的影响。 runtime.free 将在 Golang1.26
