What I bring to you today is [Operation Practice of Ukylin Open Source Community]. First of all, I will introduce myself. I am Liu Min, from Kylin Software Co., Ltd., and I am mainly responsible for the operation of Ukylin community. The topic of my speech today is mainly from the following four aspects: What is Ukylin, the development and operation model of our Ukylin open source community, the introduction of our community platform operation, and the case sharing of our community activities.

First of all, I will introduce you to the Unikylin open source community. is an open source desktop operating system based on Ubuntu, mainly a global open source project led by CCN Open Source Innovation Joint Laboratory and Kylin Software Co., Ltd. CCN mainly represents the Software and Integrated Circuit Promotion Center of the Ministry of Industry and Information Technology and Canonical, which is the parent company of Ubuntu; and our NUDT, which is the National University of Defense Technology.

We have officially become the official derivative version of Ubuntu from version 13.04, and the version we release every year is also released globally simultaneously with the upstream. The development goal of our Ukylin open source operating system is to be the world's best Linux open source desktop operating system. Our version design concept is mainly to provide users with more concise, superior, comprehensive, and intelligent products, in order to provide users with a better user experience, better product quality, and better hardware adaptation, software compatibility and The Linux operating system of the ecological environment provides users with a more community-based and more international development participation model. Our community goal is to spread open source in China and spread China to the world.

Up to now, our Unikylin community has released a total of 17 versions, including four long-term support versions. We release one version every six months and one long-term support version every two years. Up to now, our official website has accumulated more than 35 million downloads, excluding the Ubuntu official website, etc., our active fans have exceeded 200,000, and our open source projects have exceeded 68. We have contributed to the upstream More than 7000 commits have been received. At the same time, our Unikylin operating system is also an open source operating system recognized by the international community. We have contributed more than 3 million lines of code to the open source community. At the same time, our Kirin team is also the world's first open source operating system release that supports the ARM desktop, and is also the only Chinese operating system team invited to join the Linaro community.

In addition, our Unikylin Club has also made great efforts in campus promotion and the integration of production and education. At present, there are more than 50 domestic colleges and universities that have established long-term cooperation with our Unikylin community, and our Unikylin open source operating system has also entered The teaching classroom and curriculum practice of many colleges and universities. In addition, the Ukylin community has also actively participated in the open source work of China, Japan and South Korea, and served as the head of the Chinese enterprise of the Three-Country Open Source Reform Committee. At the same time, Unikylin also won the "Excellent Open Source Project in China" and the "First Prize of Science and Technology Progress of China Computer Association". In 2016, Kylin Software officially joined the Linux Foundation and became a full member of the foundation.

Next is an introduction to our community development and operation. All of our main code repositories are on our intranet GitLab, but we will synchronize all the codes to GitHub, Gitee and Launchpad three external fan development platforms in real time. Fans can use external platforms, such as Speaking of GitHub, Gitee and Launchpad, they contribute to our open source projects, and the code received by us will also be synchronized to the main repository of Gitlab on our intranet. This is the address of our Ubuntu Kylin project on GitHub. All of our operating system codes including application software are open source, so if you are interested in our project, you can download our code for reference.

We currently have 68 public projects and 213 development contributors. The following are our PR numbers and fork numbers last year. This is our UKUI project. UKUI is a desktop development environment based on Linux operating system developed by our Kylin team. It is integrated in our Kylin open source operating system by default. At the same time, it is also integrated in our winning Kylin and In the commercial release of Galaxy Kylin. Currently Ukui has 40 public sub-projects and 174 development contributors.

Our Unikylin community not only accepts contributions from the community, but also actively participates in the contributions of upstream communities, such as the Gnome community, KDE, Qt, and Linux kernel, etc. At present, we have contributed more than 7000 patches; at the same time, we are self-developed The project has also been accepted by the upstream community such as OpenStack and Centos and other open source projects.

We currently have a total of 15 core contributors to the upstream community, including our kernel community, OpenStack community, Debian community, and Ubuntu community. We have three core code reviewers in the OpenStack community, which includes 4 official projects and 50 package review permissions. This is some of our contributions to the Linux kernel community. We have a copyright@kylin module in the Linux kernel community; and our contribution to the OpenStack community. Since version F, we have contributed more than 100,000 lines of code to the OpenStack community. Among our contributions to the T version in 2019 and the U version in 2020, KylinCloud's contribution volume ranks first in China and fourth in the world. This is a contribution to the Debian community. We participated in the completion of the world's first officially released ARM64 release, and we are also the only Chinese representative among the main participants of this project. This is our contribution to the Ubuntu community. We have open sourced and included 56 open source projects in Debian and Ubuntu, including applications for system installation, input method framework, control panel, and file manager. All of our These projects received upstream have also been merged into the Ubuntu distribution.

introduced some of the contributions of our community, we found that in the development of the community, in addition to the exchange of code, the most important thing is communication. In addition to the several developer platforms mentioned above-GitHub, Code Cloud, and launchpad, we also have IRC channels that are often used by developers, and our developers will also be in it; there are also mailing lists and us Regular IRC online meetings and Google Meeting online meetings, as well as occasional offline meetings.

In addition, we also have an active testing platform. Our system testing includes the entire ISO image integration test, as well as software package testing and hardware testing. In addition to our official daily version testing, we will also hold regular meetings with other releases. Testing activities, including testing week activities with Ubuntu and Kubuntu. In addition, in the documentation and translation platform, we have contributed to the upstream translation of more than 30,000 terms and more than 100 open source technical documents. This is a translation platform of Ubuntu, and everyone can participate in all translation contributions of Ubuntu. In addition to using Ubuntu's translation platform, we have also built our own translation platform Weblate, which can work well with Github and Gitlab; currently we have received contributions from many foreign users on the weblate translation platform. There are 105 languages for translation, including English, French, Portuguese, Arabic, Polish and our minority Tibetan.

Next is an introduction to the operation of our community platform. We currently operate more than 20 official account platforms. Through the different user groups of each operating platform, we have divided the positioning of each platform, including official media information platforms, code hosting platforms, experience sharing platforms, and video sharing and Interactive communication platform.

First of all, I would like to introduce you to our official website of Unikylin.
