1月末に急にユーザーが増えた、すごく会話がやりやすい通話アプリについて、通信の内容を観察する会をした。
協力していただいた10人ぐらいの皆様、ありがとうございました。

知りたいことは、良い感じの会話を実現するボイスチャットの部分についてのみで、
オーディエンス向けの送信は、遅延を大きくしてスケールさせる、インターネットラジオと同じことをやっているだけのようなので、観察を省略した。
オーディエンス向けにミキシングするサーバーが設置されていて、そこからラジオに流し込むのだろうと推測。


観察会でわかったことの概要は、以下の通り

How to add more to Git Bash on Windows

Git for Windows comes bundled with the "Git Bash" terminal which is incredibly handy for unix-like commands on a windows machine. It is missing a few standard linux utilities, but it is easy to add ones that have a windows binary available.

The basic idea is that C:\Program Files\Git\mingw64\ is your / directory according to Git Bash (note: depending on how you installed it, the directory might be different. from the start menu, right click on the Git Bash icon and open file location. It might be something like C:\Users\name\AppData\Local\Programs\Git, the mingw64 in this directory is your root. Find it by using pwd -W). If you go to that directory, you will find the typical linux root folder structure (bin, etc, lib and so on).

If you are missing a utility, such as wget, track down a binary for windows and copy the files to the corresponding directories. Sometimes the windows binary have funny prefixes, so
