VRChat で Unity を使うに当たって、 git で Project 管理するときの耳寄り情報

※ Unity 向けの .gitignore を入れるとか、git config --global core.autocrlf false するとかはされてらっしゃるとして、それ以外の所を…

Packages/.gitignore があるので、VPMまで管理したいときは git リポジトリに入れる前にこの .gitignore を消す（しかし、VCCは Packages/.gitignore を VPM 触る度に再作成するので毎度消すことになる）か、vrc-get の GUI 実装である ALCOM でUnity Projectを作るとこれが最初から無いので便利だし、VCCより爆速でうれしい。

（古いブランチに切り替えるときなんかで事故ったりするので、 Packages も git で管理した方がいいって思ってます。）

マージは出来ないので、ベースのルナトくんからブランチ切って服着せる。みたいな使い方してます。\

Low-Latency Live Streaming for your Desktop using ffmpeg and netcat

Preamble:

In this post I will explore how to stream a video and audio capture from one computer to another using ffmpeg and netcat, with a latency below 100ms, which is good enough for presentations and general purpose remote display tasks on a local network.

The problem:

Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

General rules

Follow standard conventions.
Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
Boy scout rule. Leave the campground cleaner than you found it.
Always find root cause. Always look for the root cause of a problem.
