Is sequential IO dead in the era of the NVMe drive?

Is sequential IO dead in the era of the NVMe drive? — Jack Vanlightly
Two systems I know pretty well, Apache BookKeeper and Apache Kafka, were designed in the era of the spinning disk, the hard-drive or HDD. Hard-drives are good at sequential IO but not so good at random IO because of the relatively high seek times. No wonder…

The New Clang _ExtInt Feature Provides Exact Bitwidth Integer Types
Author: Erich Keane, Compiler Frontend Engineer, Intel Corporation
Earlier this month I finally committed a patch to implement the extended-integer type class, _ExtInt after nearly two and a half years of design and implementation.

Most C++ constructors should be explicit
All your constructors should be explicit by default.
Non-explicit constructors are for special cases.

A Linux kernel without struct buffer_head https://lwn.net/SubscriberLink/930173/c1a1f68dc4e20191/

A kernel without buffer heads
No data structures found in the Linux kernel — at least, in any version
that escaped from Linus Torvalds's development machine — are older than the
buffer head. Like many other legacies from the early days of Linux, buffer
heads have been targeted for removal…

虽然以前好像喷过，但我今天还要喷一下。

我愿称 libxdc 为学术开源屎山的典范：

没有文档；README 一大半在吹自己在某个野生 benchmark 上的高性能；代码风格混乱不统一，编辑器里面按一下保存能自动多出来几十个 change（自动删除行尾空格），缩进不统一；随处都是被注释掉的调试代码；在软件功能并不需要依赖于特定编译器或特定平台的情况下代码却大量使用 gcc 扩展特性强行依赖 gcc；作为一个 2020s 年代的新库，构建系统还在用纯手写的 Makefile；依赖管理混乱，需要用户自己把依赖预先安装在全局，且没有版本检查；没有完善的测试体系，所谓的测试就是手写的一个 main 函数随便糊弄了一下，测试覆盖率基本和 0 没差别。

总之，从软件工程角度讲，完全就是一个没有受过基本的软件工程训练的团队或个人的粗制劣造产物。而这样的库已经是学术界的优秀成果了，实在是一件非常悲哀的事情。
