The issue:

..mobile browsers will wait approximately 300ms from the time that you tap the button to fire the click event. The reason for this is that the browser is waiting to see if you are actually performing a double tap.

(from a new defunct https://developers.google.com/mobile/articles/fast_buttons article)

touch-action CSS property can be used to disable this behaviour.

touch-action: manipulation The user agent may consider touches that begin on the element only for the purposes of scrolling and continuous zooming. Any additional behaviors supported by auto are out of scope for this specification.

Problem

I have two Github accounts: oanhnn (personal) and superman (for work). I want to use both accounts on same computer (without typing password everytime, when doing git push or pull).

Solution

Use ssh keys and define host aliases in ssh config file (each alias for an account).

How to?

Generate ssh key pairs for accounts and add them to GitHub accounts.

Converting a Word Document to Markdown in One Move

The Problem

A lot of important government documents are created and saved in Microsoft Word (*.docx). But Microsoft Word is a proprietary format, and it's not really useful for presenting documents on the web. So, I wanted to find a way to convert a .docx file into markdown.

	// Since ES6 Map()'s' retain their order of insertion, it can sometimes be useful to get the last item or value inserted:

	export const getLastItemInMap = map => Array.from(map)[map.size-1]
	export const getLastKeyInMap = map => Array.from(map)[map.size-1][0]
	export const getLastValueInMap = map => Array.from(map)[map.size-1][1]

	// Obviously getLastKey and getLastValue can reuse getLastItem, but for maximum portability I opted for verbosity.
