The latest Docker, at the time of writing, does support IPv6. But there are a number of pitfalls when people try to work around this.
Here are some experiences I got, and I put a working configuration at the end of the article:
IPv6 Quick Introduction
I happened to have a chance to work on IPv6 related project, and here are some some quick insights of the IPV6 of current state. I would put in Q&A format so it might be faster to read:
Selenium RC Result UTF8 Problem
It's a long existing and fundamental problem: the HTML result after execution of Selenium HTML suite is not properly encoded as utf-8.
A detailed report could be found here:

However, it's never fixed.
How to Remotely Debug PHP
Using Terminal (Vim + VDebug + XDebug)
Scenario:
You need to debug an existing PHP site (wordpress, joomla, drupal, etc..), and you find it very difficult/time-consuming to set up your development IDE to simulate the deployed environment.
You want to have a quick look of what's actually going on, directly from the SSH terminal.
TL;DR
Use xdebug to intercept PHP scripts, and communicate with vdebug via dbgp.
(Please ignore the rest of article if you are not comfortable with vim - the editor).

One Extension for Both Chrome and Firefox
I wrote the first version of Firefox extension of Simple Gmail Notes about one and half year ago, and now I am forced to develop a new one using WebExtension technology, because the old jpm addons would be fully disabled after Firefox 57.
That was quite a surprise, because when I started to develop the extension back then, jpm was the most recommended technology for Firefox addon development. And I suffered so much during the development.
Anyway, now the the extension already got some problems with new Firefox (FF 50+), especially with the OAuth. So I am left no choice except starting on this ASAP.
