Fedora Activity Day (FAD) China 2014 was successfully held at Park Plaza of Beijing Science Park, Beijing on Mar 30 (Sunday). It was organized by Fedora Zhongwen User Group with the help of CSDN. It was under the umbrella of Open Source Technology Conference (OSTC) 2014 initiated by CSDN, being one of three parallel sessions in the afternoon. There were around 600 attendees in total, and about 200 in the FAD session.

I arrived at the venue in the morning with more than 100 Live DVDs and 500 stickers. We distributed them during the Red Hat booth as well as the afternoon session. In the morning there were several keynote speeches and one panel discussion. More details can be found in the CSDN news report.

The afternoon session began at 1:30 pm. Thomas Yao and I served as the hosts of FAD. The first talk was “About Those Python Asynchronous Concurrency Frameworks” by Fantix King, CTO at FlowForge Games, Archlinux x32 committer, and Python programmer. He introduced the concept of concurrency, compared Tornado, Twisted, and Gevent, and then introduced asyncio, the newly available framework in Python 3.4.0.

The next talk was “Reform the Toolbox: From Open Source Software to Open Source Service” by Daobing Li, the chief architect of Qiniu, who is also a Debian developer. He talked about the achievements of open source cloud service, and shared his vision of future cloud service – cloud in computer room. He also gave suggestions on how developers treat cloud services.

Next Emily Chen, GNOME.Asia founder, senior software engineer in Oracle, gave the talk “Bringing More Women to Free and Open Source Software”. She introduced the Outreach Program for Women initiated by GNOME, talked about how it increases the women participation in open source projects. The annual program provides prize for women participants in similar way with GSoC, but it does not require the applicants to be students, and applicants does not need to write code in the program.

The following talk was “Operation and Management of SHLUG” by Thomas Yao, leader of Shanghai Linux User Group (SHLUG), founder of GitCafe.com. Thomas gave an impressive speech without any slides. He talked about the history of SHLUG and shared the experience. He pointed out the pioneering effort of building the first open source mirror site in China, Geekbone, and the importance of keeping the community focus on technique rather than commercial activities. He also shared the interesting stories of Hacking Thursday and Rails Girls.

At last, Martin, leader of Beijing Linux User Group (BLUG) gave a lightining speech of introducing BLUG and its activities. Everyone is welcomed and should not worry about their English since there are actually many Chinese there. And it is quite easy to join the event by registering on BLUG website or joining discussion in mailing list.

At night there is the Open Source Night, a social event for free face-to-face discussions. Unfortunately I didn’t attend it. I had dinner with FUDCon and GNOME.Asia organizers and discussed current progress and following tasks.

Overall it is a very good event in my mind. If I have to point out some issues, I’d say there might be too many talks and no time for tea or coffee in between! Besides, my own talk was prepared in a bit hurry, and not practised well beforehand.

The slides links is available on CSDN news. They also provide a Chinese report for FAD. There is a great minute for the meeting by Bojie Li from USTC LUG. The videos and various other materials can be found at this link.

Happy new year everyone!

The Fedora 20 Release Party in Beijing was successfully held at Turing Office last Wednesday (Dec 25). It was organized by Fedora Zhongwen User Group with the help of Beijing GNOME User Group. There were 22 registrants on site, which is comparatively fewer than previous due to the time arrangement.

The release party began at 6 pm. (I was late for about 10 minutes.) We conducted the registration on a computer: We opened a LibreOffice Calc spreadsheet filled with pre-registrants’ information so that they can just type 1 to register. As for others we required them to type their names and email addresses. As usual, every attendee can pick a Live DVD and a sticker. We prepared 50 Fedora 20 DVDs. Each of them has a label with Fedora 10th anniversary icon, and is 64bit with either GNOME or KDE. The stickers are from Fedora, GitCafe, and CSDN CODE.

The party entered pizza time at around 6:30 pm. We had ordered seven pizzas, 5 large and 2 small. Along with drinks and snacks sponsored by CSDN, they more or less met the requirement of everyone’s supper. While supper we managed to collect four topics for the talk.

The talk session started from 7:30 pm. In the opening address, I welcomed everyone, and introduced the features (changes) of Fedora 20 and the 10 year history of Fedora project briefly. Then it came to the first talk, which was "systemd Introduction" by Robin Lee, an active Fedora packager, FZUG member, and skilled programmer. He talked about the origin, main concepts, and core implementation of systemd as well as its impact on application development. There were in depth discussions about the implementation details and comparison with other competitors in and after the talk.

Then there were three short talks. The first one was "Open Source Strategies of CSDN" by Orson Zhai. He pointed out that CSDN has set open source as one focus, and CSDN CODE is striving to provide a better collaboration platform for open source projects in China. Then David Liang from SUSE talked about the state and progress of "Automatic Testing for GUI". Currently there is no mature tool for automatic GUI testing to increase the efficiency of desktop testing. Projects such as openQA aim at building such tools and are being developed. The last talk was an introduction to Fedora.next by Robin Lee. Fedora.next is a plan being carried to improve the current release practice of Fedora. Based on the reflections of the existing practice, Fedora.next tries to replace the single repository with four rings of packages. Each ring can has its packaging polices. Besides, multiple working groups with possibly different release strategies are formed to build multiple products. In summary Fedora.next aims at better integration of Fedora and the overall open source ecosystem, and more involvement and contribution from more people.

We prepared several GitCafe cups, and Turing generously provided some Linux books. They were distributed as gifts for questioners. CSDN brought gifts for speakers too. Then after all the talks, at around 9:30 pm, we took a group photo.

It is worth pointing out several issues for the event. The pizzas was sent earlier than the registration, without receipts. The number of attendees is small since it was arranged at weekday night. The discussions were more abroad than expected and led to overtime. So to avoid the issues:

  • When ordering takeout, specify both the earliest and latest time.
  • To attract more people, make the event happen on weekend day (afternoon) at easily findable venue.
  • Prepare for overtime, and put the start time as early as possible.

The slides links is available on the wiki page. The photos can be found on G+. Don’t forget to take the post-event survey before Jan 11! You feedback is appreciated!

先给各位朋友道声新年快乐!

上周三(12 月 25 日)晚上在立水桥南附近的图灵办公室,由 Fedora 中文用户组主办,北京 GNOME 用户组协办,并由 CSDN 赞助的 Fedora 20 发行派对北京站活动顺利举行。由于时间是在工作日,恰逢圣诞,又是晚间活动,到场人数与以往相比偏少,最终注册了 22 人。

活动开始时间是下午六点,我迟到了十多分钟。这次注册为电子注册:在 Fedora 电脑上开一个 LibreOffice 电子表格,预报名过的人可以直接填 1 进行签到,现场报名的只需填上自己的名字和邮箱。照惯例,注册后每人可以领取一张 Live 光盘和一枚贴纸。我们准备了 50 张 Fedora 20 光盘,盘贴上有 Fedora 10 周年纪念字样,光盘有 GNOME 64 位以及 KDE 64 位两种以供选择。这次的贴纸不仅有 Fedora 的金属图标,还有 GitCafe 贴纸和 CSDN CODE 带来的 Git 主题贴纸。

大约六点半时,活动进入比萨时间。我们预订了五大两小共七个外卖比萨,加上 CSDN 赞助的零食饮品等,比较好地满足了大家的晚餐需求。在晚餐闲聊环节,我们征集到了一大三小共四个主题演讲。

演讲从七点半开始。在各个主题演讲之前,我对大家的到来表示欢迎,并简单介绍了 Fedora 20 新特性以及 Fedora 项目 10 周年的历史。之后便开始了第一个主题演讲。演讲是活跃的社区成员、Fedora 打包者李瑞彬带来的“systemd 简介”。他介绍了 systemd 的历史缘起、主要思想、实现核心,以及对程序开发的影响。大家在演讲中和演讲后对 systemd 的实现细节、与竞争者的对比等方面进行了深入的讨论。

之后是三个较短的演讲。首先是 CSDN CODE 的翟京介绍了 CSDN 的开源策略。开源已成为 CSDN 的一个重心,其推出的 CODE 平台将力图为国内开源项目提供更好的协作平台。然后是 SUSE 的 David Liang 介绍了图形界面自动化测试的现状和发展。图形界面程序的自动化测试可以极大提高图形界面测试工作的效率,但目前尚无成熟工具,OpenQA 等项目在力图打造优秀的图形界面自动化测试工具。最后一个演讲是李瑞彬对 Fedora.next 的简要介绍。Fedora.next 是 Fedora 现有发行模式的改进计划。它基于对现有模式的反思,将单一的软件仓库分为四个环 (Ring),不同环可以采取不同的打包策略,另外组建多个工作组 (Working Group),打造多个产品,不同组可以有不同的发布策略。总体上力图让 Fedora 和开源生态更好地融合,让更多人可以参与到 Fedora 项目当中。

我们事先准备了若干杯子,图灵提供了若干 Linux 图书,在问答互动环节作为奖励进行了分发。最后九点三十许,大家合影留念。

这次活动也呈现出一些问题与不足:比萨送餐人员比预定时间提前半个小时把比萨送到了,先于不少参加活动人员的到场时间,而且没有现场给发票。因为是工作日晚上,加上场地位置在五环外对于其他区的人来说相对偏远,最终现场参与的人数偏少。虽然人不多,但大家讨论交流的比较深入广泛,时间控制得不太好,最终活动结束比预定晚了半个小时。总结出来的经验教训是:

  • 外卖订餐不仅需要指定不晚于的时间,还要指定不早于的时间。记得要发票。
  • 要想让活动参与人多,最好在周末白天(下午),场地交通要方便且易找到。
  • 要有超时的准备,开始时间应尽量往前赶。

本次活动演讲的幻灯片链接可以在维基页面看到。活动照片可以在 G+ 上看到。最后,参加了活动的朋友请记得在 1 月 11 日之前填下反馈调查问卷!欢迎您对活动留下宝贵意见!
