Git:

• For introduction, please read [Documentation/Coding-Guidelines.md]

A better Git Graph:

$ git config --global alias.lg "log --graph --pretty=tformat:'%Cred%h%Creset -%C(yellow)%d%Creset %s %Cgreen(%cr) %C(bold blue)<%an>%Creset' --abbrev-commit --decorate=full"

# >>>> Better than `$ git log`:
### Now, you can use:
$ git lg 
### OR, with line changes:
$ git lg -p

Linux:

1. $ uname -r: OS check
2. $ cat /prov/version_signature: identify kernel
3. $ arp -a : Scan Local Network Devices and IPs
4. $ tree -L 1: list hierarchy of directory in depth=1

Docker:

• containerizing application with all dependencies without users to manually setup the environment

• available in all OS

• encapsulates the entire OS, so you can swap out the entire OS

• DOC: https://docs.docker.com/engine/

Environment container comparison:

Tool Name	Intro	Pro	Con
Docker	encapsulate OS environment	run the same OS on different OS platform	Huge
pyenv	python version manager	-	-
virtualenv	to encapsulate python dependencies	switching different python with different python packages with an ease	stuck with host OS
Anaconda	to maintain python virtualenv + additional sci-lib	Easier to work with	large packages
Vagrant	to provision a machine with an OS	Offer higher degree of isolation than Docker, and runs as isolated processes within the host OS	Heavier, larger and longer time to build

📓 [Isolation Level]: pyenv < virtualenv <= Anaconda < Docker < Vagrant
