Wong Ho-wa

Wong Ho-wa is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Wong Ho-wa rather than just read about it. In short: Wong Ho-wa (Chinese: 黃浩華; Jyutping: Wong4 Hou6 Waa4, also known as Howa Wong) is a Hong Kong data scientist and pro-democracy activist. He led the open government data community g0vhk from 2016 to 2021.

Key takeaways

  • Wong Ho-wa belongs to engineering; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Wong Ho-wa to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Wong Ho-wa from memory before moving on to harder problems.

Reference excerpt

Wong Ho-wa (Chinese: 黃浩華; Jyutping: Wong4 Hou6 Waa4, also known as Howa Wong) is a Hong Kong data scientist and pro-democracy activist. He led the open government data community g0vhk from 2016 to 2021. He was an Election Committee member representing the information technology (IT) industry from 2016 to 2021 and ran for the Information Technology constituency in the 2020 Hong Kong legislative election as part of the pro-democratic caucus.

Early life Wong grew up in North District, Hong Kong and lived in a public housing estate. He attended Tung Wah Group of Hospitals Kap Yan Directors' College and Saint Francis of Assisi's College, and was a three-time medallist in the Hong Kong Olympiad in Informatics. His personal interest in democratic activism began when with the 500,000-strong demonstration against the National Security Bill 2003, in which he participated as a secondary school student. He studied computer engineering at the Hong Kong University of Science and Technology and began his professional career in software engineering. He worked in Beijing in 2013–14. He relocated back to Hong Kong around the time of the Umbrella Movement protests and began taking part internet freedom advocacy alongside his data scientist career.

Open data activism In 2016, Wong founded g0vhk on the model of g0v Taiwan, a technology advocacy group for open government data. He led the creation of a g0vhk open political data platform collating attendance, speech, and voting records of incumbent Hong Kong legislative councillors, and information about candidates in the 2016 general election. Later that year, Wong ran for election to the Election Committee as a member of the IT Vision slate, part of the Democracy 300+ caucus to increase the pro-democratic camp's influence in the 2017 Hong Kong Chief Executive election. IT Vision won all 30 seats in the Information Technology subsector due to the multiple non-transferable vote system. Wong advocates that public bodies not only need to make content available to the general public, but also make them available in machine-readable formats. He criticized the complacency of civil servants who think they have complied with open data regulations but only post scan images of documents. He supports legislating a Public Records Act to codify the requirements for public bodies to disclose information, because the existing Code on Access to Information lacks enforceability. Wong believes in an approach to open data that balances the right to know and the right to privacy. He criticized the Hong Kong public sector for using privacy concerns as an excuse to withhold data, exemplifying this issue with the abundance of rumours that stemmed from the Hong Kong Police Force's reluctance to publish data about tear gas use and about arrestees at protests. On the other hand, he also campaigned against the introduction of smart lamp-posts that have the hardware capability to record pedestrians' faces. Wong opined that, even if the Hong Kong government promises not to use facial recognition technology on the lamp-post footage, such footage would be a target of cyberattacks by malicious actors with access to facial recognition. During the 2019 Hong Kong protests, Wong represented the IT industry in a Citizen's Press Conference and responded to a question about vandalism of smart lamp-posts by protesters, saying that the general public was skeptical about the true purposes of the lamp-posts. He opined that technology innovation depends on trust, thus technology policy would be meaningless unless the government attempted to regain public trust by compromising on the Five Demands. Ahead of the 2019 Hong Kong local elections, Wong led the g0vhk project Vote4.hk, which collated public data about candidates and compiled voter guides. The pro-democratic camp won a landslide victory in the elections, but Wong criticized that the district councils continued to lag behind the trend in terms of open data, citing the difficulty for the general public to obtain data about council budgets, and even where data were available often only scans of paper documents would be provided, making it difficult for citizens to monitor their council's performance. In January 2020, Wong Ho Wa and Vote4.hk colleagues Brian Leung and Nandi Wong saw that public information about the COVID-19 pandemic in Hong Kong was disorganized, so they created the COVID-19 in HK dashboard to collate information about confirmed cases, disease transmission hotspots, and surgical mask market prices. The dashboard attracted 400,000 page views per day during the peak of the pandemic and was maintained by a team of some 20 volunteers assisted by automatic web crawlers. Wong Ho Wa said that the hardest part of maintaining the dashboard was finding committed volunteers to fact-check reports of unscrupulous mask merchants. Wong criticized the Centre for Health Protection's (CHP) practice of withholding data about new COVID-19 cases from their website for many hours after their daily press conference, which forced data reusers to watch CHP's press conferences in order to obtain the latest data. Nevertheless, Wong commended the CHP for providing an API for its coronavirus case data and that the Hong Kong government's open data practices had improved significantly in the late 2010s, even though Hong Kong still fell short of the Open Knowledge Foundation's standards, lagging behind nearby regions like Shanghai and Taiwan.

Worked examples

Example 1 — a first encounter with Wong Ho-wa

Start with the simplest possible case. Write down what Wong Ho-wa claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Wong Ho-wa before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Wong Ho-wa ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Wong Ho-wa

In research
Wong Ho-wa appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Wong Ho-wa in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Wong Ho-wa is common in secondary-school and first-year university syllabi. It links to neighbouring topics Data scientists, Hong Kong democracy activists, Hong Kong engineers, so understanding it makes those chapters shorter.
In everyday life
Look for Wong Ho-wa outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
