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.

Comparing node.js GPIO implementations

Here are two simple programs testing the performance of my rpio library against popular alternatives which use the /sys interface (with the number of npm stars indicated for a rough idea of popularity).

rpi-gpio (9 stars)

This test is based on an example on the rpi-gpio page.

As modules which uses /sys depend upon asynchronous behaviour they require callbacks to ensure that the next operation starts only when the previous one has completed.
