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!

On last Saturday (Sep 21), the Software Freedom Day Activity at Tsinghua University was held. It was hosted by Tsinghua University Network Administrators (TUNA) with the assistance of Beijing GNOME User Group (BJGUG). There were more than 60 attendees. The onsite registration began at about 2 pm, and it was done on a laptop computer running LibreOffice Calc. The spreadsheet would be used by the lucky draw in the end. We prepared CDs, stickers, and posters, which were readily available for every registrants.

The formal event started at about 2:30 pm with the welcome speech by me (alick). I introduced what software freedom day (SFD) is and what free software is. I also introduced the event host and sponsors. This event was sponsored by Mozilla, COPU, GitCafe, CodeWeavers, Linux Deepin, and Fedora community. They provided many kinds of swag as gifts. Besides Mozilla also covered the cost of SFD posters and so on. I also introduced the NITE-LPI certificate program supported by COPU.

Following was three speeches. The first one was “GNOME Shell” by Li Bin, the current BJGUG leader. He talked about components of GNOME Shell and its flexible and powerful extension capability, and then demonstrated the development of GNOME Shell extensions. gnome-tweak-tool and https://extensions.gnome.org/ was introduced during the talk. The main programming language used to develop a GNOME Shell extension is Javascript. With the help of gnome-shell-extension-tool, an extension can be created rapidly.

Next was the talk “Firefox & Firefox OS” by Yuan Xulei, who is an engineer from Mozilla. He introduced the features of Firefox, and explained in details how to use addon to customize Firefox and improve the web browsing experience. Later on he talked about Firefox OS, a new open source mobile operating system by Mozilla based on Linux and Gecko technologies.

After a short break, Zhou Jianfeng, a teacher from Center for Astrophysics, Tsinghua University, gave the speech titled “Airelinux”. He first introduced Astrophysical Integrated Research Environment (AIRE), and then talked about the goal and plan of Airelinux project. Airelinux is a new Linux distribution targeted to high performance computing in astrophysics. Please join it if you are an enthusiastic astronomer, or active in the community of free software (esp. Debian), or an artist who can help with the artwork design!

There was five minutes QA for each talk. Gifts such as Firefox toys, notebooks, cups, and mouse pads were distributed.

After the speeches was the parallel demo, Hackfest and Installfest session. Small groups were formed and there were face to face talks. There were two demonstrations. One is brought by Fedora community, where Gerard, a Fedora ambassador, talked with people and encouraged them to join Fedora project. Three Fedora T-shirts were distributed. Another demo was for LPI certificate program, where Wang Yun, the country manager of LPI, explained it to interested people. The hackfest was an software defined radio experiment conducted by Wang Kang (scateu), where data was transmitted between the audio interface, and gMFSK was used to modulate/demodulate on the PC. It was quite attractive to the audience.

At about five o’clock, we had the lucky draw. It was a cute web interface, implemented in Python by Justin Wong (bigeagle). In the lucky draw 3 T-shirts and 5 CrossOver license codes were distributed. At last we had group photos.

上周六(9 月 21 日)北京天气晴好,由清华大学学生网管会 (TUNA) 主办,并由北京 GNOME 用户组 (BJGUG) 协办的自由软件日清华站活动顺利举行。活动有超过 60 人参加。接近下午两点时开始现场注册,这次活动的注册为电子注册,每个人在注册电脑上的 LibreOffice 表格中填写各自的信息,这个表格会被最后幸运抽奖的程序直接读取。我们准备了光盘、贴纸与宣传海报,注册后每人都可以领取。

活动正式开始于大约两点半。开场时由我(赵涛)致欢迎辞。我在欢迎辞中介绍了什么是自由软件日活动、什么是自由软件,此外介绍了活动的主办方和赞助单位。本次活动得到了谋智网络 (Mozilla)、中国开源软件推进联盟 (COPU)、GitCafe、CodeWeavers、深度 Linux、Fedora 社区等的大力支持,他们为本次活动提供了丰富多样的礼品,其中 Mozilla 还对活动宣传品等的开销提供支持。我还对 COPU 支持的 NITE-LPI 联合认证项目做了介绍。

之后便开始了主题演讲环节。第一个演讲由 BJGUG 主席李彬带来,题为“GNOME Shell”。李彬在演讲中介绍了 GNOME Shell 的组成,灵活强大的扩展 (extension) 机制,还现场演示了扩展开发。演讲中推荐了 gnome-tweak-tool 和 https://extensions.gnome.org/ 网站。GNOME Shell 扩展开发主要使用 Javascript,借助于已有的扩展框架生成工具 gnome-shell-extension-tool,扩展可以很快捷地被开发出来。

每个演讲最后都留有大约五分钟时间进行问答,问答互动环节的奖励有火狐玩偶、笔记本、塑料杯、鼠标垫等。

主题演讲环节之后,是并行的展台展示、Hackfest、Installfest 环节,这个环节大家分成若干小组,进行面对面的交流。展台有两个,其一是 Fedora 社区的展示,Fedora 大使吉拉德 (gbraad) 在现场和大家做了深入交流,鼓励大家加入 Fedora 项目,并送出了 3 件 Fedora T 恤。另外一个展台是对 LPI 认证项目的介绍,LPI 中国区经理王雲老师为大家做了答疑解惑,她表示今后会在高校做更多的活动介绍 LPI 项目。Hackfest 则是有王康带来的软件无线电实验。这个实验用声卡进行信息传输,在电脑上用 gMFSK 做调制解调,使现场同学领略到了软件无线电的魅力。

五点左右时,活动来到了最后的幸运抽奖环节,抽奖程序是一个卖萌的网页界面,主体逻辑由 Python 语言实现,作者是 Justin Wong (bigeagle)。我们抽奖送出了 3 件 T 恤衫和 5 个 CrossOver 正版序列号,其中序列号在活动后邮件送出。活动最后大家合影留念。

整个活动过程中也遇到了一些问题。一是筹备期间教室借下来的时间较晚,海报宣传时间不足一周,又恰逢中秋放假,使得线下宣传力度不够。微博大屏幕、人人活动墙的想法没有及时提出,未能实现。二是在开场前注册所用电脑到的较晚,加上电子注册、输入法的问题等,使得注册缓慢,活动比预计推迟了约半个小时正式开始。第三是礼品发放有些混乱,部分礼品被热情的在场同学一抢而空,大概是因为没有明确说明中场休息时只有提问的同学可以上台领取礼品。给今后活动的启示是:早借教室早宣传,注册工作要做好准备尽早到位,礼品发放必须说明规则避免混乱。
