How fast are Linux pipes anyway? (2022) thumbnail

How fast are Linux pipes anyway? (2022)

In this post, we will explore how Unix pipes are implemented in Linux by iteratively optimizing a test program that writes and reads data through a pipe.1 We will begin with a simple program with a throughput of around 3.5GiB/s, and improve its performance twentyfold. The improvements will be informed by profiling the program using

GNOME 42带来新的屏幕截图应用 界面大改 thumbnail

GNOME 42带来新的屏幕截图应用 界面大改

去年Google Summer of Code期间,GNOME开发了一个更新的屏幕截图和屏幕记录器用户界面,这个改进后的截图/截屏用户界面在本周被合并到GNOME 42中。在此之前,GNOME允许屏幕录制,但这是通过组合键来完成而不是通过GNOME Screenshot用户界面。 只有键盘快捷键才能调出的屏幕录制启动很显然对用户不是很友好,不仅如此,GNOME截屏应用还缺乏在替代品中发现的各种功能。GNOME 42的这个新实现能够从一个单一的用户界面提供屏幕截图和屏幕录像,它本身已经是GNOME Shell的一部分。新的屏幕截图界面在代码审查了五个月后于本周被合并,同时也取决于各种Mutter的变化,今天合并的是新用户界面的截屏部分。通过GSoC学生开发者Ivan Molodetskikh的这篇博文,可以了解到更多关于这个新的GNOME屏幕截图界面的细节:https://imolodetskikh.wordpress.com/2021/06/29/gsoc-2021-gnome-shell-screenshot-ui/在即将于3月23日发布的GNOME 42.0中,可以看到这个新的用户界面和许多其他功能。了解更多:https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1954
