a professor at Illinois got frustrated with existing systems programming textbooks

so he started a wikibook project and had students help write it

it covers C, processes, threads, synchronization, memory allocation, networking, filesystems, scheduling and security

Introduction to Parallel Algorithms

[Vivek Galatage @vivekgalatage]

One of the best free courses on low-level performance programming - Aalto University's Programming Parallel Computers covers SIMD, pipelining, cache optimization, and more.

If you care about squeezing CPU cycles, this is definitely worth taking up.

If you want to actually understand memory allocation, read this by @TheGingerBill.

A series so damn good.

If you're making technical decisions that shape a system, you're already doing software architecture.

The difference is whether you're doing it intentionally.

In Grokking Software Architecture, @codeliftsleep gives developers the vocabulary, frameworks, and thinking process needed to make better long-term technical decisions.

In this CppCon 2022 presentation, Jan Bielak discusses strategies for writing efficient C++ programs - a good talk.

[swar09 @swarnitghule]

spend time on learning cache memory today

1. L1i, L1d,L2, L3 cache
2.SRAM VS DRAM
3.cache locality
4.cache miss/hit rate
5.cache lines
6.false sharing
7.cache line bouncing
8.cache thrashing , LRU, P-LRU, random, LFU etc

tomorrow i will start simd and os internals.

If you've ever wanted to understand how debuggers work under the hood with a deep dive, this blog series is for you.

"Writing a Debugger From Scratch" by @timmisiak - 8 parts covering everything from attaching to a process all the way to source and symbols.

[tetsuo @tetsuoai]

char (*(*x[3])(void))[5];

If reading that took you more than a few seconds, you want the right-left rule from Peter van der Linden's Expert C Programming.

Start at the name, look right, then left. When parentheses block you, pop out and keep going.

x
right: [3] → array of 3
left: * → pointers to
right: (void) → functions (no args) returning
left: * → pointers to
right: [5] → arrays of 5
left: char → char

So:

x is an array of 3 pointers to functions returning pointers to arrays of 5 char.

C declarations are weird. This book teaches you how to read them.

即使现在看 Netflix 的这篇文章，还是觉得 Troubleshooting 最有意思了。

从 Docker 到 containerd，频繁的 bind mount 为每层做 idmap，导致系统死锁或者超时。最后定位到了与 CPU 架构还有关系，在 m7i 和 m7a 实例上出现了显著的性能差异，最后还给上游提交了 PR 解决
