本文永久链接 – https://tonybai.com/2025/09/30/good-taste-in-software-engineering 大家好，我是Tony Bai。 在软件工程领域，我们习惯于用“技术能力”（Technical Skill）来衡量一位工程师的优劣。他是否精通并发模型？能否写出高性能的代码？对底层原理的理解有多深？这些能力可以通过学习和重复练习来获得，是我们评价体系中的“硬通货”。 然而，github工程师Sean Goedecke在他最新的博文...| Tony Bai

Operating systems expose a wall clock that can leap or slew with NTP and a monotonic clock that never runs backward.

In high-performance applications, managing tasks concurrently can help maximize efficiency and reduce execution time. One common concurrency pattern for task processing is the Worker Pool.

They present an easy way to insert pieces of code in the kernel which are compiled to opcodes which are guaranteed to not crash it: The instructions allowed are limited, backward jumps are not allowed (so no indefinite looping!) and you can’t dereference pointers, but can instead do checked reads from pointers which can fail without panicking the entire system. You can attach an eBPF to thousands of hooks in the Linux kernel - uprobes, kprobes, tracepoints, even things like p...| nikofil’s blog
