What did we do?

Jackathon is short for “Journalism-Hackathon”. At Initium Lab, we aim to push limits of Journalism with Technology. We hold regular Jackathons to advance our knowledge and skills in using new technology for obtaining data, analysing information, and reporting.

This week, the goal for each participant is to read one the the 60 Data Science books collected by KDnuggets within 8 hours.
Participants could pick one or two books to finish reading in 8 hours and present findings / insights to the others.

We have promised you an English version of our video about the voting patterns of Hong Kong Legislative Council.
And here it is.

The video is also available on YouTube and Youku.

對於冥王星這樣巨大、遙遠、陌生的物體，要表達其尺寸，常用的辦法是給它找個參考系。問題是，選什麼呢？今天我們帶領大家討論一下， 如何更好的表達冥王星的尺寸。

中國有五百萬盲人^[註1]， 接近香港的總人口。 加上弱視，總數超過一千二百萬^[註2]。

• 文匯報：黑褸賊書局偷盲貓 片段網上瘋傳
• 東方日報：盲貓「福仔」被尋回　主人喜與愛貓重聚
• 蘋果日報：被偷5日　疑賊人送往愛協　盲貓「福仔」回家了
  等等……

香港立法會選舉中，為甚麼有的議案需要地區直選及功能界別的同時過半可獲通過? 而有的議案只需獲得過半數投票贊成，即為通過呢? 出席，同意，反對，棄權，四個按鍵又分別有什麼功能呢?
