## 第 1 天：7 月 19 日

COSCUP 正式活动于周末两天在中研院举行。周六我早起在住处附近吃过早饭后搭公车（大陆称公交）前往会场。刚开始搞错了方向，耽误了些时间，不过也了解到台湾的公车是需要摆手才会到站停车的。到会场后找到演讲者签到处，很快拿到了会议袋，内有一本议程册和一件 Polo 衫和若干宣传页。COSCUP 并行演讲有 7 个之多，人文馆一层楼的会议室装不下，以至于一半的演讲在另外一个楼，名叫学术活动中心。好在 keynote 时全场地联播，各个分会场都可以实时看到主会场的画面，能够有效地分流观众。我的演讲安排在学术活动中心的一个房间，并且就在 keynote 之后，所以我提前去那个楼了。

keynote 行将结束时，我就前往 H3 会议室，准备我的演讲了。H3 是个小会议室，挺容易坐满的。我的主题是 Fedora.next: What’s Next?，开始前我先做了个小调查，发现在场听说过、用过 Fedora 的用户还不少。在演讲中我还是先简单介绍了 Fedora 项目及其四项基本点，然后介绍了 Fedora.next 这一架构提案的缘起、内容、以及当前进展情况。Fedora.next 目前仍是一个比较新的概念，这个演讲的主要目的是让中文社区的朋友更紧密地跟进说英语的核心社区，为社区未来发展做出更多更为核心的贡献。

BoF 结束后，Max 请我和 tonghui 去他们住处附近的宁夏夜市，体验台北小吃。最初我们大陆团计划去师大夜市，不过得知那里的夜市氛围已大不如前。宁夏夜市位于宁夏街，一条不长的街道，但路两边小吃店和小吃摊琳琅满目。Max 带我们体验了炒粉(?)、豆花、还有记不清名字的带馅丸子，我们纷纷表示很好吃，并未事先没有预留肚子表示遗憾。据了解，台北小吃可以吃到晚上两三点，相应地公车和捷运的末班也都较晚，不由感慨台湾人民夜生活之幸福。

## 结语

Note: This is a press style report of FUDCon APAC 2014, which summarizes the event highlights. Don’t miss the links to slides, videos, and photos!

FUDCon APAC 2014 was successfully held at Conference Center at New Main Building of Beihang University, Beijing, China during May 23 to 25, 2014. This year the event was held together with GNOME.Asia Summit, an annual conference for GNOME users and developers in Asia. It turns out to be a rather exciting experience of mutually beneficial cooperation of free and open source communities. In total, GNOME.Asia and FUDCon APAC 2014 attracted more than 500 registrants, and among them over 300 attended the event.

There were 52 speakers in total and among them 22 are for FUDCon. Thanks to the help with the community budget, many non-local speakers joined the event and made FUDCon Beijing a big gather up for the Fedora community. The speakers delivered a wide range of topics about free and open source technologies and communities presented in keynote speeches and five parallel tracks. Richard Stallman gave a keynote speech on Computing, Freedom, and Privacy, which is the favorite speech according to the feedback survey. Talks in FUDCon tracks cover various subprojects of Fedora, as well as new application introduction and community building discussion. The links to all slides are available at the wiki page. As for the videos, they are currently available at the GNOME.Asia channel on Youtube. The Fedora Videos team is working to make them available on Fedora channel.

There were about 50 volunteers at the event. They were recruited from the local universities and companies. They showed great enthusiam and did amazing jobs to make the event well organized. Two of them, Tong Hui from GNOME and Zamir Sun from Fedora, were each awarded the prize of best volunteer, a hand fan full of wishes in various languages written by the attendees.

It is worth pointing out that about ten percent of the attendees are women. Many of them are active volunteers and talented speakers. Still more women contributors are expected in free and open source communities. And there was a dedicated session, Fedora Women initiated by Nitesh, to discuss the issue and possible solutions.

FUDCon is not just about technical sessions. It is also about meeting friends and having fun. FUDPub was organized as a welcome party, and there was a celebration party with delicious buffet on Sunday evening. On Saturday there were sports games including football, baseketball, and ping-pong. These social events helped the attendees enjoy the conference and the community.

Special thanks go to the sponsors. FUDCon was sponsored by 7 companies and 5 local communities. The success would be impossible without their generous support. There were 14 booths for sponsoring companies and local communities at the joint event. Attendees enjoyed hanging around the booths for discussion, and many swags were distributed at the booths.

Photos and Reports from various attendees are aggregated on the wiki page. The FUDCon Beijing Badge has been created and is in the process of collecting FAS usernames at the current writing.

This is my own (unofficial) report of FUDCon APAC 2014 Day 2 (Sunday).

## Main Hall

The hosts in the main hall on Sunday were Tobi from GNOME and Tommy He from Fedora. The sessions began with the keynote speech on Systemd by Lennart Poettering. He talked about what is the modern Linux system and what role Systemd plays in it. Pity I didn’t finish listening to the talk, since I was asked out to help with hacking room. It turns out quite a few guys would like a separate hacking room. So we decided to open up Room 2 for hacking. Shortly after setting it up, the most important guest, Richard Stallman (RMS), came to the venue along with Zeuux guys and others. They were not happy with the booth setup (it was the last booth) until an exchange was made. They brought many swags, and some of them are to be sold rather than given away. Richard also went into the hack room since it was still some time from his keynote.

After Lennart’s talk there were four lightning talks. It’s such a pity that I missed them all, in particular biergaizi’s lightning talk on “Tips about Linux Servers”. Then RMS’s keynote on “Computing, Freedom and Privacy” began. Many more people were coming and filling up the main hall. RMS’s talk itself is not quite new to me since I had listened to him in Tsinghua. The part about why GNOME was created at all was new, but the history was already familiar to Linux hobbyists. However, being able to listen to his talk on site was quite impressive and educating. I have the feeling that his opinion might be ahead of the time but is always right. In the middle of the talk, he held an auction for a toy gnu and “an adorable book” (Free Software, Free Society). After the talk was the Q&A, which lasted till about 12:45. We went to Heyi Building for lunch after that.

At lunch I got the message from zsun that Ankur would like to have the GPG key signing party in a small room rather than main hall. That was doable and we had difficulties to find a substitute to fill in the empty slot in main hall. At last the signing party was held in Room 2 and there was no replacement in main hall.

## Room 3

After lunch it was near 14:00, and the first talk in Room 3 was supposed to be mine. So I hurried there to prepare. The volunteers (Feng Tian, Justin Wong, Rosie Ye, Tang Zhixin, etc.) were ready. I began my talk on LaTeX Tips a little bit later than the schedule. I talked about common compilation errors and output errors and how to fix them. The time was limited so I skipped the part about math formulas and BibTeX errors. I got a question about the main advantages of LaTeX compared with GUI Office applications. I explained that the advantages lie in high quality output and automatic generation of table-of-contents and list-of-various-stuff. Users normally only focus on the main contents rather than formatting issues.

The second talk was “CD using Docker” by Gerard Braad. He explained the actual definition of CD, Consistent Development and Deployment, and use Docker to demonstrate the concept. He introduced PaaS, LXC, cgroups, Dokku and so on along the talk. The talk was presented in an interactive and interesting way: questions, answers, and gifts!

After that there were only 10 minutes for tea break. However it was a nice time to take photos in front of the large banner. The following talk was meant to be Carbo Kuo’s Batsh topic, but he could not come and had sent regrets on Saturday. So Cheer Xiao’s talk was moved upwards to fill in the slot. Cheer Xiao talked about his experiments with Elvish, a new Unix shell created by himself. There were many considerations and tradeoffs when designing a shell, and he introduced the philosophy behind his choices. He also compared it with existing shells such as fish and zsh.

There was no more talks in Room 3 afterwards, so we headed for Room 8 to join the discussion about Fedora Women.

## Room 8

The last talk in Room 8 was “Fedora Women” by Nitesh. He would like to make it more an interactive discussion than an oral presentation, and asked zsun and me to help translate. The session turned out to be quite productive. There were many nice suggestions out of the discussion. The main points are summarized as follows (with relevant names in parentheses):

• For online communications such as IRC in a diverse community like Fedora, people generally do not know whether one is a man or woman, so there is normally no discrimination against gender. The community is equal to men and women. Potential women contributors should not fear questions such as why do you code you are a girl. If there is any such question, it is more important what is one’s interest than what is others’ opinion. (Nitesh, Ankur, Feng Tian)

• Fedora has many roles and tasks for contributors. Even if you do not like coding, you can try to join the design team or the translation (L10N) team or others to contribute. Fedora also has a lot of special interest groups (SIGs) which welcomes people with that special interest, such as electronics, cloud computing and so on. And there is the opportunity to start a new SIG. There is a SIG called Fedora Join SIG, which is an ideal place for people who are new to the project and do not know what exactly they should do. You can just do informal introduction in the Join SIG mailing list and people will help you find what you can do. (Jaroslav, Aditya, Nitesh, Ankur)

• There are many tasks waiting for people to join and contribute. And there will be many new tasks since Fedora.next is coming. Some of them are easyfix ones, which is very suitable for new contributors to get started. (Ankur, Jaroslav)

• The local communities should draw the attention of outside non-users, organize activities to help them especially women to install Fedora on their computer and to show them how things work in the communities. Among the activities some can be girls oriented. Besides, blogging about how to install the OS and how to do various things on Fedora! (Martin, Aditya, Nitesh)

• Lovely dolls attract girls! We should design more stuff than stickers for offline events. (Feng Tian, zsun)

• Fedora might have a narrower user base than other projects like GNOME. But people can actually contribute to Fedora even without using it everyday. The way can be bug reporting, translating, or volunteering in offline events, etc. (Justin Wong, zsun)

• A question to current contributors: why do you fail to bring your girlfriend to the community? (Robin Lee)

• We should continue the discussion after the conference, rather than raising the same question again on the next conference. We should setup activities talking about how to achieve something, especially in Beijing. We should have clear targets. (Martin)

## Closing

We went back to the main hall for the closing part of the event, and found the last talk in the main hall had not been finished, and it also became a discussion. So it seems we should consider panel discussion as a session type in the future.

The closing speech was given by Kat (IIRC) and Jaroslav respectively, and then followed by the speech by the local team. Emily and I went on the stage. She spoke in English and I did the translation. We gave our thanks to everyone, especially hardworking volunteers. The two hand fans, full of writings in different languages, were given to Tong Hui and Zamir Sun respectively as gifts for best volunteer of each community. The top horizontal scroll for the couplet was decided to be “Happy Hacking” according to the result of two days’ voting. At last we had a group photo.

## Evening

In the evening we had a very nice buffet dinner at Oasis Café, Vision Hotel, which is just behind the conference venue. We toasted to everyone and thanked them for coming. I sat with robyduck and zsun. We talked about a lot of things including robyduck’s travel plan. Robyduck also pointed out a possible issue with FZUG’s logo. Richard Stallman also went to the celebration party. Besides, zsun and I stood in front of the camera of Nitesh near the cafe since we promised to participate the short interview by him and Ankur. It was such a relax at the dinner after two days’ event and after several months’ preparation. And I was really happy that many people found the event good and successful.

This is my own (unofficial) report of FUDCon APAC 2014 Day 1 (Saturday).

## Registration

Tonghui and I went up early, had a simple breakfast at the hotel, and then went to the venue. I took the Live DVDs along, and the box was kind of heavy (about 400 DVDs!). Many volunteers were already there and ready when we arrived. Christopher was there too and needed to find a hotel for the night. Robin Lee offered him help. I took out about 50 DVDs and put them at the Fedora booth, and told the volunteers at registration desks to distribute the remaining ones. I took out some and put them close to the desks while left others in the box. It turned out to be not so good since the ones in the box were left unnoticed by the volunteers and were not distributed. But they can be used in future events anyway. It rained at night, so we expect fewer attendees than usual. Later in the night I got the message there was above 200 registrants on Saturday, which is a pretty good number.

As for the swags (gifts) for attendees, we prepared sufficient conference bags and badges, and each bag had a Fedora flyer, a Fedora DVD, a Deepin DVD, and some flyers from various sponsors. It was good except several issues. The paper of Fedora flyer is soft (157g paper) and the bag is soft (basketball bag or so), which makes the flyer easily rumpled. Another issue is that the Deepin DVD was not together with Deepin brochure.

Although we had enough bags, there were not sufficient T-shirts. We had decided to provide each volunteer two T-shirts, one from GNOME and one from Fedora. Also we need to reserve T-shirts for designers, speakers and donate tickets buyers. Therefore not many T-shirts were left for normal attendees, so they had to be distributed in a first-come, first-served manner.

## Main Hall

The sessions at main hall began with loud sound of a Chinese gong. The hosts are Max from GNOME and Gerard (gbraad) from Fedora. Kat and Jaroslav gave the welcome speech from each side respectively. Then Emily represented the local team and introduced the event and also called for voting for the top horizontal scroll for the couplet — Evolution of the Desktop, Innovation for the Community — which is the conference theme. The former of the two parts was proposed by GNOME folks. It took some time for me and other Fedora guys to think of the latter half.

Then it was the time for keynote speeches. First Tobi gave a nice overview of GNOME 3.12 features. Then Jiri and Jaroslav introduced Fedora.next to the audience, talking about the features and the community. Pity I didn’t finish listening to their talk, since I needed to head to Room 8 to prepare following Fedora sessions. One of the most important thing was to bring a Fedora Friend Finder (power strip) there!

## Room 8

When I arrived at Room 8, the volunteers (Shi Jie, Ma jing, Fan Jiayue and others) were already there. Shi Jie was the host of Room 8 on Saturday. His introduction scripts were outdated and could not reflect real schedule that day, but he adjusted quickly with the help of kraks. Ma Jing was the coordinator in that room, and was in charge of distributing gifts (books and cups) to questioners. Fan Jiayue was responsible for posting news on SNS websites (weibo) and preparing the daily news report.

The first speech was “Fedora Videos” by Nitesh Narayan Lal. He talked about one main current work is to organize all the videos. It is worth pointing out Nitesh (together with Ankur) was also responsible for recoding short videos of interview with random attendees.

Then Robert Mayr from Italy gave us the talk “Fedora Websites – present and future”. The talk was quite interesting and the new design for Fedora.next was quite impressive. Currently there are no APAC contributors for Websites subproject. Hopefully we will have interested APAC folks join the team. Robert also showed the easyfix page and Tommy asked about the feasibility of localizing it.

The morning sessions ended after that, and then we went to lunch at Heyi Building in Beihang. I met Nitesh and Aditya there, and helped them to tell the cook they need vegan food. There was a short period when no one was taking care of the booth. Zamir helped and I asked dongfengweixiao to be there quickly.

At 14:00 the afternoon session started. First Aditya Patawari from India talked about “Orchestration with Ansible at Fedora Project.” He is from the infra team, and he talked about why they moved to Ansible, and how to use Ansible to executive ad hoc commands and create playbooks.

Then Zamir Sun brought a brief introduction to FirewallD. He introduced the advantage of FirewallD, the GUI and command line interface of FirewallD, and the rich language to define complex rules. He also called for help on localization of FirewallD wiki pages and software applications.

Then it was a tea break. Unfortunately there was no drinkable tea since (we thought) there was no hot spoiled water at the venue. But the registration desks were moved to the side and the large banner stood out, which became a very good background to take photos. The booth was also quite popular, partially due to the lovely chameleon dolls brought by SUSE. I also met Su Zhe, the author of venerable SCIM, by the introduction of Emily at the booth. Su Zhe shared some information about Google’s input method project, and told that they are planning to release the input method framework open source.

After the break I went to the main hall to listen to Peng Wu’s “Wayland intro with i18n hacks”. I came in a bit late and only caught the part of two patches for wayland and a demo to run wayland for debugging. Su Zhe raised questions difficult to answer about Wayland and Mir.

After that I went back to Room 8 for Ankur Sinha’s hackfest about “ROS on Fedora”. Ankur introduced ROS and Fedora packaging. The talk was finished early but there was not much time for hacking. Ankur planned hacking on the next day. So we had more discussions, including Fedora Join SIG.

Then all the sessions for Room 8 on Saturday ended. We volunteers, speakers, and some attendees took a group photo, and then went back to the main hall.

Note: Ankur’s report contains more photos!

## Main Hall Again

In the main hall we had three lightning talks, and they were Deepin Desktop Environment (DDE) from Xia Bin, Chandao FIXME from Wang chunsheng, and Open Build Service (OBS) from Lance Wang. Then we reached the closing part of first day. A wonderful video of short interviews was created by the volunteers and presented. We also had volunteers take a group photo.

## Evening

I originally intended to join the sports game after the one day’s sessions, but at that time I was with tiansworld, tommy, and Wang Ye. I needed to help tiansworld to check in at the hotel, but we decided to have dinner first. We searched around the street outside East Gate of Beihang, and settled at Hannashan eating Korean toast. The food was good and not so expensive with groupon. But it would be not so good without conversation! We talked a lot, and after the dinner, Wang Ye left but liangsuilong joined the conversation at McDonald’s. We talked about all kinds of stuff, Fedora related or not. The conversation lasted to over 11:00 PM until I got a message from tonghui, asking whether I was back. We agreed it was a bit late, and it was time to say goodbye and go for rest.

When tiansworld and I were back at the hotel, I helped with the check-in at the front desk. Most of the staff there are not proficient with English, and zsun had reminded me that we needed to speak of 亚洲峰会 (Chinese for Asia Summit) to let them know which group we belonged to. After it was done, we went upstairs to each one’s room. Finally I had time to revise my slides for Sunday. Check the git log if you want to know the detailed changes. While I was preparing the slides, tonghui was checking the photos taken in the day. There are many good photos to tell the truth! It was quite late in the night after I finished my slides, so I went sleep quickly.

This is my own (unofficial) report of FUDCon APAC 2014 Day 0 (Friday).

## Preparation

There were no speech sessions for FUDCon on Friday, so it was all about event preparation in the day. At around 11:00 AM, I called Justin Wong, another guy from TUNA, also a volunteer of host, to help me move event gifts in my lab downstairs, where Emily waited for us with her car. We went to the venue, New Main Building in Beihang University, on the car full with sponsored gifts, including but not limited to cafe cups, hats, DVDs, books. Dongfengweixiao also just arrived when we got there. We had a brief lunch together at PengLaoShi, a Chinese fast food restaurant.

On the way back to the venue after lunch, we ordered the bottled drinking water for the three days. In the afternoon we are busy with setting up everything. Zamir (zsun) arrived to help. First we set up the booth with the desks rent from venue as well as desks from Beihang leagues (credit Wang Yang). The shop owner of bottle water helped with moving the desks from outside to venue. We had a booth for Fedora too, which dongfengweixiao took care of, so we left some Fedora flyers (and later on many stickers, F20 Live DVDs) there. We met one guy in orange T-shirt while setting up the booth. He asked about the place for upcoming GNOME training sessions. The next day I knew it was Tobi, the host in main hall from GNOME side!

Tong Hui (tonghui) arrived later and then event roll-up posters, X posters, and vertical banners arrived. I helped to hang up the two vertical banners in the main hall with tonghui and dongfengweixiao. It took three up-and-downs to finally make them look good (symmetric and smooth). Next I helped to buy some utilities such as power strips, mark pens, glue, and “postit” sticky notes. I also fetched the express of stickers. After I came back, many sponsors were there. There were some disagreements with booth position, but they were solved later. Li Bin (libin) and many other volunteers also arrived, and the registration desks (sign-in office) was set up. They put various small gifts into conference bags. T-shirts arrived and classified. Large banner which sat on the ground arrived a bit late, but was put up quickly. Time went by without being noticed, and it was almost 7 o’clock when we headed for the FUDPub, i.e. the welcome party.

## FUDPub (Welcome Party)

The FUDPub was at Sculpture in Time Cafe, a cafe bar on campus and quite near to the venue. It was scheduled to begin from 6:00 PM, and we had volunteers waiting there to help from that time. As mentioned above some volunteers and I arrived a little late, and there were few empty seats then. Some early birds already begin to drink beer when we started to order pizzas and noodles! Around 60 people from the event were there, and the cafe bar seemed to be not able to handle so many people. The service was slow and a bit chaotic, but luckily we had sunny (and later on libin) who took care of the detailed list of ordered and served food. Except the long waiting time for food, it was good. I met and said hello to Ankur, Nitesh and other guys. Max called on emily, libin and me to toast to everyone. Ankur asked to continue discussion at the hotel after the party, but I stayed till 10:00 PM at the cafe bar since tonghui had so many interesting stories to tell! While we went to the hotel, I picked up the Fedora 20 Live DVDs with GNOME Desktop, whose creation was finished late due to some issues with DVD sleeves during production.

## Hotel

The conference hotel is Beihang Training Center, which is inside Beihang and near to the conference venue. There was no WiFi at hotel, only one wired interface available. Luckily tonghui set up a WiFi AP using his laptop with GNOME 3.12. He also charged his camera for next days’ activities. I replied some emails, took a shower, and then went to bed. I had planned to revise my slides, but it had to be delayed to Saturday.

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 second talk was “Use Linux Command Line as a Hacker” by Xiaodong Xu (Toy), the webmaster of LinuxToy. He shared a lot of command line tips to fix typos, manipulate shell history, and speed up operations. In the QA session he talked about his opinion on text editor choice and Linux distro choice.

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.

Following the talk was “Introduction to HackRF & GNURadio” by Scateu Wang, the creator of hackrf.net and the former leader of TUNA. He demonstrated the ease of using GNU Radio to develop software defined radio applications for DTMF decoding, FM modulation and demodulation, digital audio broadcasting, etc. He also introduced HackRF, the newly created inexpensive hardware peripheral used with GNU Radio.

The next talk was “Fedora Ambassadors & FUDCon” by myself. I introduced the four foundations of Fedora Project, gave an overview of Fedora Ambassadors project, showed what ambassadors do and how reimbursement works, and then shared the recent progress of organizing FUDCon APAC 2014 to be held in May and welcomed everyone to join.

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.

After that is the panel discussion on “History and Future of Open Source OS in China”. It was moderated by Thomas Yao, and the panelists are Weijia He from Redflag College of Education, Jianzhong Huang from Redflag R&D, Jack Yu from UbuntuKylin, and Yong Wang from Linux Deepin. They shared their opinions and experiences about Linux Desktop, collaboration of distros, cultivation of open source talents, and open source in education.

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.

NOTE: For Chinese readers, there is a Chinese version of the report here.

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!

• 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。
