Simple canvas-based color converter

To answer this StackOverflow question I wrote this — a small solution based on a never-rendered <canvas> element. It fills a 1-pixel canvas with the provided fill-style, and then reads the RGBA values of that pixel. It will work with any CSS color -- name, rgba(), hex, or even something more exotic like a gradient or pattern. Invalid colors are always returned as transparent black. Transparent colors are treated as painted on a newly-cleared canvas.

It's been tested in modern-ish versions of IE, Chrome, Safari, and Firefox. The API is:

color_convert.to_hex(color)   # Converts color to a hex-based RGB triple; to_hex('red') returns '#ff0000'
color_convert.to_rgba(color)  # Converts color to an rgba() string; to_rgba('red') returns 'rgba(255,0,0,1)'

Converting a Word Document to Markdown in Two Moves

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.

The Solution

As it turns out, there are several open-source tools that allow for conversion between file types. Pandoc is one of them, and it's powerful. In fact, pandoc's website says "If you need to convert files from one markup format into another, pandoc is your swiss-army knife." But, although pandoc can convert from markdown into .docx, it doesn't work in the other direction.

Setup a Local Only SMTP Email Server (Linux, Unix, Mac)

1 - Point localhost.com to your machine

Most of programs will not accept an email using just @localhost as domain. So, edit /etc/hosts file to make the domain localhost.com point to your machine, including this content to the file:

127.0.0.1 localhost.com
