한글과 유니코드

유니코드에서 한글을 어떻게 다루는지를 정리하였다.

유니코드

유니코드(Unicode)는 전 세계의 모든 문자를 컴퓨터에서 일관되게 표현하고 다룰 수 있도록 설계된 산업 표준 (위키 백과)
단순히 문자마다 번호를 붙임
계속 업데이트되며 현재는 Unicode Version 9.0.0 이 최신이다.

UTF

유니코드를 실제 파일 등에 어떻게 기록할 것인지를 표준화한 것이다.

ANSI Escape Sequences

Standard escape codes are prefixed with Escape:

Ctrl-Key: ^[
Octal: \033
Unicode: \u001b
Hexadecimal: \x1B
Decimal: 27

Download courses from learning sites with `youtube-dl`

You can download whole courses from an array of tutorial sites with the CLI tool youtube-dl. In the example further down I'm using my Pluralsight account to get videos from a course at their site. Here is a list of all supported sites that you can download from with this tool

The flags you have to supply may vary depending on which site you make a request to.

You can get a free 3 month trial to Pluralsight by signing up for free to Visual Studio Dev Essentials

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)'
