埃隆·马斯克： “普通人生活中几乎所有的不幸，都是由精确性的丧失开始的。”
现在的年轻人可能已经无法想象：有人能把阅读几千字高密度文字，当作刷短视频一样轻松。这是一种被系统训练出来的能力。…
优质信息正在越来越难获取。
valgrind 或者 asan 这些，都只能在程序结束时生成一份报告，对于长时间运行，无法轻易结束的服务程序并不友好，而且有时候不是要差泄漏，而是要差那么多内存用到哪里去了，用量分析，这时候更好用的工具就是 gperftools 的 HeapProfiler 可以中途开启，手动按需导出占用报告共你对比分析，还有调用栈

同样是采访，出自传统财经媒体 (比如 CNBC) 的专业人士制作的访谈节目，尤其是那种把时间压力当成职业习惯的人，感觉特别肤浅和让人不舒服，这体现于两点： 1.…

#工程师学习 看到一本不错的在线版本的书籍「深入架构原理与落地实践」，较完整地介绍了架构体系，贯穿 underlay网络、容器与云原生网络、网关实践、微服务与分布式、云原生、质量监测以及成本管理方面的主题，帮助工程师快速理解架构体系全貌，可以周末来看看。 🤖️thebyte.com.cn
再次推荐这本书: Unit Testing, Principles, Practices, and Patterns 它在工程角度非常好的指引了 Unit Testing (领域逻辑) 和Integration Testing(带有外部依赖)怎么实践 🔥

最近一直在学 Rust，发现一个比较好的材料 github.com/kaist-cp/cs431 专门用 Rust 讲并发编程的。老师也是 crossbeam 的主要维护者之一。讲了各种锁、无锁数据结构的实现，作业里也需要动手实现各种无锁数据结构。非常棒！
@pshufb I might ask them how a linker works. Pay attention to name mangling, how symbol overloads are dealt with, the role of external and static, one definition rule, inline keyword, forward declaration of template instantiation, there’s scope in there to discover ecosystem knowledge.
这篇VLDB的文章描绘了斯坦福、MIT、Google和VMware的一些工程师的野望：使用分布式OLTP数据库构建下一代云操作系统。其目标是从UNIX“万物皆文件”的理念进化到“万物皆表”。这个想法听起来比较超脱，但是也有很多情理之中的点：数据库本身就喜欢自己实现系统服务，内核bypass也是最近研究的热点
