Six-Hour with Geeks: A Glance into Hong Kong Open Source Movement

Loads of imagination about programming has been running helter-skelter in my mind before I step into the spacious and well-polished Spectrum studio on the 11th floor of an office building at Sheung Wan in this bright Saturday morning. As someone who has been concentrating only on courses about liberal arts since senior school, I always consider coding as something far away from my daily life.

But today, Chico Xu, Ivy Wang and I, as student reporters, are going to take a glance into this sophisticated business which we once thought was irrelevant to the lives of us and the lives of many, but which actually is, and to a large extent.

The event we are attending is called the Global Pandas Documentation Sprint, a worldwide event held simultaneously in more than 300 countries on March 10, 2018, aiming at improving this Python library’s documentation with clearer explanations and better examples, and trying to leave, at the end of the day, with the library enhanced “in a perfect state,” as put by its official website.

How China Blockbuster War Movies Capture China’s Nationalism

Summary: China Blockbuster War Movies become more and more popular in the global. The national movie frequently takes on the responsibility of representing the national identity to its citizens or even the world. How does China Blockbuster War Movies Capture China’s Nationalism? What is the opinion of the public? We used Douban as the source to extract data from the film reviews of two movies (“Operation Red Sea” and “Wolf Warrior” ) on the Douban, a popular art consumption and rating website, to figure out the thought of people behind the screen and the future development of Blockbuster War Movies in China. With the help of Python, we made a Wordcloud picture of the frequent words included in the 1,000 pieces of films reviews for each movie. We found that China’s new breed of patriotic hero on the big screen reflects the rise of a superpower and  China’s War Movies is shaping the image of China.

Last month, movie tickets sales in mainland China hit 10.1 billion yuan ($1.6 billion), a box office world record for monthly sales in a single market. No film stood out more than “Operation Red Sea.”, which had grossed almost 2.5 billion yuan in just 13 days by the end of February.

 “Operation Red Sea” is based on the Chinese navy’s March 2015 evacuation of Yemen. Set amid militant unrest in a fictional Middle Eastern country, it tells the stories of a ship’s crew and an assault team as they rescue Chinese citizens and foreign refugees, resolving a potential nuclear crisis along the way.

Similarly, last summer’s blockbuster “Wolf Warrior 2,” ($854 million), tells the stories of a loose-cannon Chinese soldier in an unnamed African country. “Operation Red Sea” tones down the patriotism of last year’s smash hit film ‘Wolf Warrior 2’, playing up gore over glorifying war.

How does China Blockbuster War Movies Capture China’s Nationalism? What are the opinion of the public in China and the globe? Can these films be a step towards making Chinese action films more palatable overseas? We will make some Analysis based on the data.

National Congress: signs for a clearer sky in Beijing

SummaryIn this article, we collected the data of the air quality in Beijing over the past 5 years.We assumed that the significant changes or improvements in air quality were related to China’s two top Annual Sessions – the Chinese People’s Political Consultative Congress (CPPCC) and the National People’s Congress (NPC).Besides, there were several news and current affairs affected the air quality in Beijing. We will also take a closer look at its air quality at that time to see if there are significant pollutants reductions during those periods.

Four years ago, the Chinese premier, Li Keqiang, said at the National People’s Congress and many more Chinese citizens watching live on state television, “We will resolutely declare war against pollution as we declare war against poverty”.

Since then, cities have cut concentrations of fine particles in the air by 32 percent on average. Just a few months before the premier’s speech, the country has released a national air quality action plan to require all urban areas to reduce concentrations of fine particulate matter pollution by at least 10 percent. As the capital city, Beijing was required to reduce pollution by 25 percent, of which the city set aside a massive $120 billion yuan to achieve this target.

All the statics in this project comes from Online China’s Air Quality , which is a public platform monitoring and analyzing China’s air quality covering statistics from 367 cities with AQI, PM2.5, PM10, S02, N02, O3, CO, temperature, humidity, wind scale, wind direction, satellite cloud picture and so on.

In this project, we mainly focus on Beijing’s air quality including AQI, air pollution category, and main pollutants such as PM2.5 during December 2013 to March 2018.

Analyze tracking errors between ETF and stock market index in the last decade

5571521786922_.pic_hd.jpgSummary: In this article, under the context of Hong Kong’s Mandatory Provident Fund scheme (MPF), we find that some Exchange Traded Fund (ETF) occupy large holdings in a particular MPF fund. By calculating the tracking errors over the past ten years, the year of 2008 stands out with the highest tracking error, which corresponds with the global financial crisis. In other years with more stable stock markets, ETF performs relatively well. We also calculate returns between two ETFs and the indexes they track respectively; the results turn out to be different.

We use Python as a calculator, rely on pandas to read csv files downloaded from Yahoo Finance, and time series to present data in the form of charts.

Background

Hong Kong has a rapidly aging society. According to the Population Projections released by Census and Statistics Department, HK is expected to have a third of its population that aged 65 and above by the mid of 21st century. There is a growing concern over the issue of social security especially for the elderly, since the burden for the employed population in the future to take care of the retirees will be unbearable.

Data News of the Week: Hong Kong Legislative By-Election 2018

The hope for pro-democracy camp to regain its veto power in the legislature vanished as Edward Yiu Chung Yim failed to beat his rival Vincent Cheng Wing-shun in last week’s by-election.

Legislative By-election 2018 was held on 11 March for four vacant seats in the council, following after the oath-taking saga which disqualified six councilors. New legislators were elected from three regions – New Territories East, Kowloon West, and Hong Kong Island, as well as Architectural, Surveying, Planning and Landscape functional constituency.

Election is all about numbers – voter turnout rate, numbers of votes, and percentage of voters supporting candidate A or B, making it a golden opportunity for data visualization. In this article, we select three local news media, which are Initium, SCMP, and HK01, to discuss their different coverages on the by-election.

Data News of the Week: Sexual Assault Around The World

If you are a woman who is walking down the street alone in the late night, and accidentally you meet a group of guys hanging out with nowhere to go, what would happen when you pass them?

It may be the words “hey, beauty” or “hey, sexy girl,” or being instructed to smile. Or maybe more intentional: standing in the way or blocking the path in hope of some interaction. Or perhaps may get more aggressive, with hands reaching to inappropriate places. Actually, this kind of situation is far and wide, with one end harboring the potential for things to become more violent with physical abuse or rape. In Canada, the United States and The United Kingdom, women being sexually assaulted has become a serious problem. However, there is still a loophole after asking the police for help – Will the police believe you?

A 20-month investigation by The Globe and Mail reveals that sexual-assault victims are more likely to be believed in some areas of the country than in others. Continue reading “Data News of the Week: Sexual Assault Around The World”
