git config --global -e

git config --global user.name git config --global user.email git config --global alias. . ???

git config --system core.editor git config --global --edit

1. you should have folder

2. cd training

3. git init

4. git config

5. create some files - transient

6. add files to git (let git know your files) - you can rollback git rm --cached

7. you can commit

8. create repo in github https://github.com/adithnaveen/swiggy-2020-july.git

9. refer to your local folder to github git push origin master

10. on the chat put your github link

git log git log --oneline git log --oneline -n 3 (last 3 commit information)

how to do branching

to locate which branch you are working

git branch

create a branch

git branch new-branch

change your branch from one to another

git checkout new-branch

-- make some changes git add . git commit -m "added some files"

git checkout master

-- merge

git merge new-branch

git push origin master git push origin new-branch

github.com/yourname/repo

• Developer Dev code
• Testers Test Cases
• DevOps no test cases executable only source code (application logic)
• Automation

GO Lang

C / C++ Socket programming Threading (fork) Matrix Multiplication Doing system calls open MP - parallel programming Terminal base file explorer Computer Graphics Gaming - TIC-TAC-TOE Oops Works (encapsulation, polymorphism, pure virtual function, inheritance) Design Pattern recursion regex Data structures + LinkedList Semi conductor Remote Control Heater Light controller

Java Tomcat - HTTP -> servlet Slow will not talk to computers directly Hashcode

go Lang - will look like c

C/ C++ - x pages JAVA - x+x pages class myclass extends Thread { public void run() { // bl } }

class myclass implements Runnable { public void run() { // bl } }

go lang - x-50% (very compact) + C + Java + API (web server, socket programming, rest server) ver 1.0 2012 ver 1.14 2020

• c code - it return a the value to OS + the executable is in underlying OS (WIN-WIN, MAC-MAC) #include <conio.h> #include <stdio.h>

void main(){ printf("hi") ; return ; }

• java program (platform, WIN-MAC, MAC-LINUX) public class HelloWorld { public static void main(String args[]){ System.out.println("hello") } }

var x := 25

print statement in java

// since System is a class, and class shall have pascal casing (Starts with Upper Case, every words first char is Uppercase ) System.out.println("Hlo") ;

step 1: write program step 2: go run program.go or

go build program.go ./program

to see documentation

go doc ex: go doc fmt

to format your source code

go fmt program.go

src bin pkg

export GOPATH=/Volumes/Kanchan/MyTrainings/swiggy-2020/workspace/go-works-goland/go-structuring export GOBIN=/Volumes/Kanchan/MyTrainings/swiggy-2020/workspace/go-works-goland/go-structuring/bin

cd src go install Test.go (this will create an executable file in bin )
cd ../bin ls (Test) ./Test

you can get the list of the supported OS in this format $ go tool dist list
