The Rise and Rise of ICO in late 2017

If you still don’t know what is “blockchain” or what is “bitcoin”, The recent work from Max Galka will assure you this is the high time to do some self-study, or you will miss the birth time of “another Internet”. The idea of ICO, Initial Coin/Chain Offering, is an analogy of IPO. With the inception of “smart contract” capability, fundraising, a process to exchange currency to certificate, can be done in a distributed manner. The “currency” in the chain world can be Ethereum, NEO, BitCoin, … The “certificate” in the chain world is called “token” so the ICO process is also referred to as “token sale”. The convenience of ICO gains rapid growth with crazy capitals pouring into this field. Just check out this interactive/ animated token sale history.

My First Application of FOI in Hong Kong

It was new for me when I heard anyone can acquire almost any data from HK government for legitimate reasons under that Code on Access to Information.

This code is a response to the notion of “FOI” (For Our Information; Freedom Of Information), which calls for citizens’ free access to government information so that the transparency of government management can be ensured and citizen rights can be protected.

According to Wiki, In 2006, nearly 70 countries went through relative legislation. Among these laws are USA’s FOIA (Freedom of Information Act) and, of course, Hong Kong’s Code on Access to information.

Despite the code in place, a practical question remains. Will those government officers fulfill their duty and do give reply to every single data request? So I decided to give a try on Accessinfo.hk.

Accessinfo.hk is a website positioned as a platform for citizens to post their information requests to authorities and receive feedback. It was initiated by a group of Open Data activist, including Guy Freeman, who is currently data scientist in HK01. The website publishes every question and answer to everyone, and, at the same time, monitors the process. Before localizing the Alaveteli system ( http://alaveteli.org/ ) to Hong Kong, its sister site WhatDoTheyKnow ( https://www.whatdotheyknow.com/ ) had already seen wide application in the United Kingdom.

The whole tax bill cuts the corporate tax rate from 35% to 21% and the top individual tax rate will drop to 37%, which used to be 39.6% in 2017.

The following chart shows the progressive tax rate before and after the bill, in one Table. We find that table is an effective way to display data with high density. It seems the tax will be deducted for everyone except for the lowest income bracket.

The process involves picking up programming skills and becoming comfortable with both front-end web development and back-end dev ops. He will also touch on the exciting process of visualising data, as well as some of the common questions and obstacles new comers may face, how to overcome them, and progressively acquaint themselves with the work-flow of a web-based data visualisation storytelling piece.
