The Composable Architecture

The Composable Architecture(TCA)는 일관되고 이해할 수 있는 방식으로 어플리케이션을 만들기 위해 탄생한 라이브러리입니다. 합성(Composition), 테스팅(Testing) 그리고 인체 공학(Ergonomics)을 염두에 둔 TCA는 SwiftUI, UIKit을 지원하며 모든 애플 플랫폼(iOS, macOS, tvOS, watchOS)에서 사용 가능합니다.

Error Handling in Practice

My experience is mostly with Java backend services in the cloud, so the advice in this post will almost certainly be biased towards this kind of error handling. But hopefully, some of it will be generally applicable and help you maintain and debug your programs in the long run.

I don't claim that these are universal best practices, but I have found these to be useful as general guidelines. As always, use your best judgment and do things that make sense in your context.

Log the whole thing

In Java, a full exception is:

	import sys
	import socket
	import select
	import random
	from itertools import cycle

	# dumb netcat server, short tcp connection
	# $ ~ while true ; do nc -l 8888 < server1.html; done
	# $ ~ while true ; do nc -l 9999 < server2.html; done
	SERVER_POOL = [('10.157.0.238', 8888)]
