Hi!雖然因為 #武漢肺炎 關係,我地近來取消咗好多meetups,但我地一路以來仍然好希望用唔同嘅方法,運用我地嘅專長同技術,推廣 #技術普及 ,引導更多嘅IT人才去實現夢想、承擔社會責任。

用科技影響社會,呢個係 #GDG 一直以來嘅目標之一。

我地嘅Co-organizer Orix Au Yeung 今日就用咗#GoogleMapsPlatform 嘅 #GeocodingAPI 同 #GoogleSheets 嚟將大家近來都好關注嘅被強制檢疫人士嘅清單可視化,有幸得到近二千share!

Hello there! Despite recently we cancelled many meetups due to the outbreak of #coronavirus, we have been busy in trying to use our expertise and skills in a lot of ways promoting #TechnicalLiteracy and in turn encouraging more IT professionals to achieve their goals & take up more social responsibilities.

It has been always one of our goals of #GDG to change the society we are living in through technology.

Today, our co-organizer, Orix Au Yeung, used the #GeocodingAPI in #GoogleMapsPlatform & #GoogleSheets to visualize something the public has been concerned a lot: The list of Compulsory Quarantine of persons due to the virus! It is our pleasure to announce that currently his post has reached nearly 2,000 shares on Facebook.

GDG Devfest Hong Kong 2019 CANCELLED

Due to the current condition of Hong Kong, we are sorry to announce that our GDG DevFest Hong Kong 2019 has been canceled.

We have not taken this decision lightly, and have kept hope until last week that the situation would improve (enough) so we could still hold a great event. Our participants and speakers Safety is always our top priority, therefore, we unfortunately have to make this tough decision.

We hope we will see you soon.

(CANCELLED) GDG DevFest Hong Kong 2019

== GDG Devfest Hong Kong 2019 CANCELLED ==
== [Announcement Detail] ==


本年度 GDG DevFest 將於11月23日於香港城市大學舉行。今年我們將兵分四路,帶來超過20個環節,涵蓋Cloud Technologies,Machine Learning,MobileWeb等不同範疇。


一個良好的生態圈並不能單靠我們這一群開發者,所以今年我們亦邀請了 Women Techmakers,將我們的願景帶給每一個人。

GDG DevFest 是一個免費的活動,由開發者舉辦,為開發者而設。在這裡你將會得到由Google,行業領袖,科創企業,及本地社區所帶來的行業資訊。

Event 網站

GDG DevFest, our annual developer conference for the developer community, will be held on 23-Nov in City University of Hong Kong. This year, we have one more track compare with last year. We have 4 tracks and over 16 sessions covering areas of Cloud Technologies, Machine Learning, Mobile, Web, and more.

Since 2010, DevFest has become our largest event of the year. From one single track with 80 people, to 4 tracks with over 300 people. We bring the best to the community, to build a sustainable ecosystem in the industry.

Not only more sessions for more people. We understand a healthy ecosystem cannot be just formed by us. So, this year, we also bring Women Techmakers with us. To bring the same message to the young developers, and beyond the limit of genders.

With speakers from Google, Industry Leads, Startups, and Local Communities, we bring the best content to the community. If you miss it, you will have to wait for another year. And most important is, the event is FREE.
