-- This is the Astricon Dangerous Demo application logic built in Lua,
-- and conceived to be used in conjunction with the janus_lua.c plugin.
-- It only uses data channels, and expects commands to control the ARI.

-- Note: this example depends on lua-json to do JSON processing
-- (http://luaforge.net/projects/luajson/) and on lua-http for HTTP
-- requests (https://daurnimator.github.io/lua-http/)

backup dotfiles

• Following will copy all of dot ~/. files and directories (including its contents) directly underneath home directory.
• To avoid copying cache and other local configs, e.g., that of web browser, java apps, etc., preferably query directory size tool under entire home $HOME/, using ncdu $HOME of similar tool.
• Exclude all those large directories using rsync --exclude=.local --exclude=.cache format
• Avoid rsync password, ssh keys, .bash_history, etc. if you are uploading to github, etc.
• rsync home dotfiles and configs as follows:

# in your local machine

Streaming your Linux desktop to Youtube and Twitch via Nvidia's NVENC and VAAPI:

Considerations to take when live streaming:

The following best practice observations apply when using a hardware-based encoder for live streaming to any platform:

1. Set the buffer size (-bufsize:v) equal to the target bitrate (-b:v). You want to ensure that you're encoding in CBR mode.

2. Set up the encoders as shown:
