an additional feature of the desktop, the Dash. The Dash is designed to make it easier to find, open, and use apps, files, music, and more. For example, if you type the word "document" into the Search workspaces, removable devices and the trash. If an application that you want to start using is present in the Launcher, you can click on that application's icon, and it will start up, ready for you to not, if the icon is for an application whether it's running or not, and on the specific icon itself. Available actions can include the following. launching the application or opening the document,

03 Technical White Paper openEuler is an open source Linux release platform. In the openEuler community, global developers join hands to build an open, diversified, and architecture-inclusive software build a unified and open OS that supports multiple processor architectures, and to advance the hardware and software application ecosystem. On December 31, 2019, the openEuler open source OS community release of openEuler 20.09 is a milestone in the growth of the openEuler community and the history of open source in China. On March 31, 2021, the innovative version openEuler 21.03 was released. This version

computing, edge computing, and embedded deployment. It provides a secure, stable, and easy-to-use open source OS that is compatible with multiple computing architectures. openEuler suits operational and communications technology (ICT). The openEuler open source community is a portal available to global developers, with the goal of building an open, diversified, and architecture-inclusive software history of helping enterprises develop their software, hardware, and applications. The openEuler open source community was officially established on December 31, 2019, with the original focus of innovating

Glossary Introduction to Cilium What is Cilium? Cilium is open source software for transparently securing the network connectivity between application services deployed using Linux container management platforms the Linux kernel, Cilium security policies can be applied and updated without any changes to the application code or container configuration. Why Cilium? The development of modern datacenter applications shifted to a service-oriented architecture often referred to as microservices, wherein a large application is split into small independent services that communicate with each other via APIs using lightweight

noted that both editions use the same apt repositories, making it just as easy to install a server application on the Desktop Edition as it is on the Server Edition. The differences between the two editions allow the system to boot to a degraded array as well: • When the server is booting press Shift to open the Grub menu. • Press e to edit your kernel command options. • Press the down arrow to highlight necessary files, meta-data, and instructions to implement a particular functionality or software application on your Ubuntu computer. Debian package files typically have the extension '.deb', and usually
