The ability to write code in assembly is essential to achieving the best performance for a GPU program.This post explains how to produce Hsaco from assembly.

Linux系统top命令中的iowait究竟是什么意思？发表于 2019-08-08 21:08:56 | 已被 访问: 1,487 次 | 分类于: Linux笔记最近在做连续数据流的缓冲系统，C语言代码实现后，粗略测试了下，功能上应该没有问题。那么，…

请注意本文并不是推荐读者使用 Xen 作为虚拟化方案，相反，KVM 才是目前更合适大部分读者的方案。 简介 由于工作需要，最近我需要搞一个 Xen PV 来进行测试，在此之前我一直使用 qemu/KVM，只是听说 Xen 是 KVM 之前流行过的虚拟化方案。比起几乎什么都不需要做交给 libvirt 包办就可以的 KVM，Xen 的设置相对要复杂一点。

若存在，请举例说明；若不存在，该如何证明？

slirp4netns provides user-mode networking (“slirp”) for unprivileged network namespaces. This is heavily used in rootless-containers.

I couldn't find in google any safe way to clear systemd journal. Do anyone know any safe and reliable way to do so?

背景 我们一般会使用 fail2ban 来保护暴露到公网的提供密码登录的 ssh 连接等。 但使用 frp 穿透后所有的从外网访问都会变成 127.0.0.1 进入的，原本能用 fail2ban 保护的如 ssh 服务将无法使用。 因此 fail2ban 应该放到 frps 服务器上。但 frps

Is there a tool (or an algorithm) to convert a finite state machine into a regular expression?

(not the other way around, that would be easy).

Fsm2Regex is a Web application for transforming finite state machines to regular expressions and regexes to FSMs.

Converting regular expressions into (minimal) NFA that accept the same language is easy with standard algorithms, e.g. Thompson's algorithm. The other direction seems to be more tedious, though, and

GCC, MSVC, LLVM, and probably other toolchains have support for link-time (whole program) optimization to allow optimization of calls among compilation units.

Is there a reason not to enable this ...

I have a dd image of disk, which is a LUKS container containing a filesystme, and which I can loop mount and unlock to access the files. The filesystem in the container is only about 1/4 full. Wh...
