Last week, I was very honored to get sponsored to participate the Hanoi SFD 2014. I joined the Fedora meetup on Friday and gave a talk on Saturday. Below is the full report.

Day 0 (2014-09-18): Arrival Day

I left Beijing early in the morning and in the afternoon stayed in Hong Kong Airport to transfer. The flight to Hanoi was a bit late, and I arrived at the Hanoi Airport at around 8:00 PM (local time, 9:00 PM in Beijing time). The weather was wet and hot, but the people are nice. It took me some time to find a large shuttle bus, rather than the minibus. On the bus I met a Japanese guy, and it turned out he lived in a hotel not far from mine. So after getting off the bus, we walked to our hotels together most of the way.

It was about 10:00 PM when I arrived at the hotel. I shared a room with Sarup (banas), and he told me they (Thang, Somvannda, Tuan and others) would like to have me together go out for beer. I was a bit tired after the long trip, but after ten minutes’ rest, I joined them. Thang carried me on his motorbike to a street corner nearby, and I met Tuan (for the first time) and Somvannda (for the second time). I was surprised to find many people are there on the street at first. But I soon realized having cool beer outside is the best way to pass the hot night. By cool I mean not only temperature (ice beer), but also the taste (nice beer).

Day 1 (2014-09-19): Fedora Meetup

On Friday morning we went to the VAIP office and had a Fedora APAC ambassador meetup the whole day. The meetup was set up for APAC ambassadors to discuss critical tasks. EMEA has had a lot of similar meetups, but for APAC, it was the first to my knowledge. (It was at least the first in this year.) To include remote participants who cannot make it at Hanoi, we also joined the #fedora-apac IRC channel. There we met gnokii, kushal, FranciscoD, etc. We also set up a pad on PiratePad.

In the morning, we discussed many issues including the budget status, current issues and so on. It seems the major issue is that not many APAC ambassadors are active, and people do not regularly attend meetings. In China, the state is somewhat better: we do have a few active contributors and we managed to have regular IRC meetings and offline activities (release parties every release, yearly FAD, and FUDCon Beijing). In India there is another problem: there might be too many ambassadors and some people tend to use Fedora as a travel agency. We agreed that people need actively participate biweekly meetings and mailing list discussions to get their tickets approved easily, and to be considered as active, one ambassador needs to organize (or help organize) at least one event per year.

We also talked about the FAD Phnom Penh under planning and the ambassador Polo shirts. The FAD planning is generally in good shape. I saw no Taiwan ambassador registered the event but I think they should consider. Regarding the Polo shirts, unfortunately the Fedora logo on the sample shirt is incorrect and needs to be fixed. And the quality of the shirt is not quite high. I am supposed to ask local vendors in China to see if we can get better ones within a reasonable price. We went on to discuss general swag production issues. gnokii suggested that good quality can be produced in Europe for both EMEA and APAC regions. Besides, China can be one good candidate among the locations to store the swag.

I also learned from Tuan about why we APAC folks lose some money when getting reimbursed by paypal while Americans not. The reason is that US paypal accounts have the option to cover the transaction fee by the sender, while other accounts do not. So the fee is charged at the receiver side, causing the loss. To walk around the issue, we might let APAC CC holder izhar set up a US paypal account.

In the afternoon, after a short pizza lunch, we carried on remaining tasks. We spent quite some time in summarizing the budget usage in previous quarters. It was sad to find that none of the planned events in Q2 happened at last. To solve the budget problem, we adjusted the budget allocation for the remaining quarters, and came up with ideas of possible events. After that, we talked about Fedora sessions for the SFD next day. At last, Somvannda asked us to share stories of being an Fedora ambassador. For me, it was the simple idea of organizing regular events to gather existing contributors and attract newcomers, and the idea of starting something by oneself when no one else has started it.

In the evening, we went to see the water puppet show, which is fun and amazing. At dinner we had delicious dishes and noodles, and Saigon beer! But we did not stay up too late at night, since we felt quite tired after one day’s meeting, and we need to prepare for SFD in the next day.

Day 2 (2014-09-20): Hanoi SFD 2014

Saturday was the Software Freedom Day (SFD), a global event to celebrate Free and Open Source Software (FOSS). I organized SFD in Tsinghua University last year, and it is lucky for me to be part of SFD Hanoi this year. Hanoi SFD is organized by VFOSSA, the FOSS association in Vietnam. Fedora was one main sponsor of the event. It was a whole day event held in a university. So many volunteers are students and employees of the university. It was fun that the event begins with volunteers dancing, both in the morning and in the afternoon, and they are so good at it!

In the morning are welcome and keynote sessions in one large lecture hall. Sarup, Somvannda, and I are honored to be introduced as special international guests to the event (in English). They awarded new members and event sponsors in the welcome session. Later in the keynote session, Tuan delivered a speech on seven ways to contribute to Fedora (without coding). Most of the morning sessions were in Vietnamese, and I could only understand a little bit. I brought some Fedora 20 DVDs, stickers, and flyers from China, and they were distributed very soon at the booth.

In the afternoon, we had a dedicated room for Fedora related sessions. First, Thang gave a general introduction of the Fedora Project to the audience in Vietnamese. Then I talked about free and open source software defined radio (FOSS SDR). With a lot of examples, I introduced why we should have FOSS SDR, and how FOSS SDR can enable hacking in the radio frequency. I introduced GNU Radio and various SDR hardware such as HackRF and bladeRF to show how FOSS and open hardware play well with each other. Since the talk was in English, and the topic is not so familiar, the main purpose of the talk was to show the power of FOSS and open hardware, and to encourage the audience to try out and contribute to FOSS projects.

Later on, Sarup delivered a FOSS 101 talk. He talked about why we should choose FOSS, how newcomers join and contribute to Fedora, and main communication tools of FOSS communities. Then he gave an introduction on Git and version control concepts. I helped demonstrate the git operations, and Trang helped translate for easy understanding.

At around 4:00 PM, we gathered to one room again. There was a panel Q&A session followed by the lucky draw. The panel session was quite interactive, and the audience raised many questions. One interesting thing is that the panel speakers voted for the best question and there was an award for that questioner. Then in the lucky draw, it turned out we foreigners were not so lucky. None of us was chosen. But lucky draw is always fun for everyone.

In the evening, we had dinner with the organizers and volunteers of SFD. We drank beer and toast to each other. I even learned how to toast in Vietnamese!

Day 3 (2014-09-21): One Day Tour

On Sunday, Somvannda and Sarup left for the airport early in the morning. My flight was around at 7:00 PM, so I took a one day tour in Hanoi. I visited Quang Truong Ba Dinh (Ba Dinh Square), Ho Chi Minh’s Stilt House, Ho Chi Minh Museum, One Pillar Pagoda, the Flag Tower, Hanoi Cathedral, and so on. The sight spots are relatively near to each other, so I travelled around mostly by walking. I had lunch at Quan An Ngon, a popular restaurant in Hanoi, and bought some candies and gifts to bring back to China. In the afternoon, on the way back to the airport, I also walked by the Ho Hoan Kiem (Hoan Kiem Lake). The sight spots are nice, and the food is delicious. So I enjoyed the trip to Hanoi a lot. Plus the warm support and help from Tuan, Thang, Somvannda, Sarup, and others, the days in Hanoi are quite memorable to me.

本月 11 号到 14 号,因为参加学术会议的缘故,去了一趟深圳和香港。日程很紧,时间有限,不过我还是挤出来些时间感受下当地的景致。学术方面的会议总结已经在实验室里做了交流,这里的看官一般也不会感兴趣,因此本文就只描述会议之余的行程。

我是 11 号周日上午从学校出发坐地铁换机场快线去的首都国际机场,在机场快线上时只见窗外大雾弥漫,只觉是要延误。到了机场登机口时,外面就雷声轰鸣,不一会儿就大雨倾注,延误无误了。最后,九点半的飞机,十点多登机,下午一点时分才起飞。起飞时外面还是有雾,不过已大大好过之前。

第一次坐飞机,起飞时拉起升空的感觉很棒。遇到颠簸时下坠又有些心虚。由于是第一次且是白天,所以选了靠窗的位置,以便拍照。在空中飞行时窗外的蓝天和云海是非常漂亮的。

近三个小时的飞行后,飞机降落在深圳宝安机场。在跑道上滑行时深圳突然又下起了不小的阵雨。

由于当晚要住香港,所以下飞机后乘 330 路直奔罗湖口岸,在进港的关口排起了长队,队里等待时间大概有半个小时。之后乘地铁东港线去大学站。不禁为港中文有如此霸气的站名感叹。香港地铁不挤,但票价贵,和北京正相反。在那边一个大学同学的热情帮助下,吃了晚饭,摸到了晚上住宿的地点。晚上是住在港中文的国际生舍堂三座,是三人间,感觉比在自己学校住的都宽敞(也许是房间比较空产生的错觉),后来发现另外两人是来自华为的参会者。住的地方是在山上(学校其实就是依山建的),可谓海景房,能看到两侧高楼林立的沙田海夜景。值得一提的是,港中文有许多电梯,方便学生爬山,不是同学指路我是断然想不到的。另外还有免费的校车,只是假期车次较少。另外,在住的地方第一次见到并用了会掉冰块的饮水机,显然是后知后觉会用的。

第二天白天是会议时间,午饭是在晨兴书院的餐厅。饭后有一小段时间到餐厅外侧看了看风景,不由的打开相机按下了许多次。

下午茶歇时顺便逛了会议地点(康本国际学术园)一楼的书店,买到了朋友托付要买的书。会后要办香港住处的 check out,而已经过了他们的工作时间。后来得到了一位同学的积极帮助,等待了一段时间后顺利地 check out。等待期间是在学校外面附近的凯悦酒店,回头拍了几下港中文。其实我只走过了港中文的一个角落,里面的校区都没有工夫转。

之后,素未谋面的 fqj 童鞋帮我解决了晚饭,此时已经是晚上八点多钟。一番思虑之后,我决定冒着回深圳后赶不上地铁的风险,去尖沙咀维多利亚港看一看。fqj 表示也没看过维多利亚港夜景,愿意同行。于是我们倒地铁到了尖沙咀,出来后因为不知道路又找了一会儿,终于找到了海边,到了星光大道。海边风大,颇为凉爽。游客也不少。

IMG_2794 IMG_2800

从海边返回已经是十点多钟,待我到罗湖深圳一侧,恰为 11 点,地铁末班已经赶不上了。于是排队等出租车。到了住的地方,却被告知查不到预约信息。折腾一番,零点半方真正入住。我住的地方离深圳的华强北很近,也算是深圳的一个知名地段。

IMG_2900 IMG_2906

周二周三白天都是会议。周三晚上我就得回北京,所以尽管周二晚上是阵雨天气,我还是去了一趟东门老街。这里其实就是商业街、步行街、加小吃街,但是建筑可以看到是旧时的楼宇。另外当天晚上是七夕,街上有不少卖花的。

周三香港是八级风球预警,上午那边会议的日程都取消了。这让我一度认为当晚在深圳恐怕走不了了。然而深圳一直是台风黄色预警没有升级,下午等到了是航班晚点而非取消的消息。本来是 19:15 的飞机,晚点通知是改为 20:25,最终是九点多一些起飞,零点到的北京。之后坐机场大巴和出租车回到了宿舍,结束了四天匆匆的行程。

时间虽紧,但也算逛了一逛。在我待的几天里,香港天气很好,风景很赞,大学里的人们都很帮忙,说普通话也没问题;深圳雨水有点多,但空气质量优良。总体印象很好,唯愿今后能有机会去更多地了解。
