How To Work With Multiple Github Accounts on a single Machine

Let suppose I have two github accounts, https://github.com/rahul-office and https://github.com/rahul-personal. Now i want to setup my mac to easily talk to both the github accounts.

NOTE: This logic can be extended to more than two accounts also. :)

The setup can be done in 5 easy steps:

Steps:

Step 1 : Create SSH keys for all accounts
Step 2 : Add SSH keys to SSH Agent

This is a reconstruction of http://www.roman10.net/2011/11/27/how-to-calculate-iptcpudp-checksumpart-2-implementation/ The site is gone so I took it from the archive for the sake of C Programming TCP Checksum's answer Enjoy! All credits go to https://github.com/roman10.

This is a follow up of the previous post, how to calculate IP/TCP/UDP checksum part 1 — theory.

IP Header Checksum Calculation Implementation

To calculate the IP checksum, one can use the code below,

Step 1 - Create a New SSH Key

We need to generate a unique SSH key for our second GitHub account.

ssh-keygen -t rsa -C "your-email-address"

Be careful that you don't over-write your existing key for your personal account. Instead, when prompted, save the file as id_rsa_COMPANY. In my case, I've saved the file to ~/.ssh/id_rsa_work.

Step 2 - Attach the New Key

See this SO answer.

Disable large send offload in host on vEthernet (to avoid messing with non-virtual adapters). Disable larg send offload in guest for all adapters (unable to predict adapter names and probably all of them are real).

Pushing to Multiple Git Repos

If a project has to have multiple git repos (e.g. Bitbucket and Github) then it's better that they remain in sync.

Usually this would involve pushing each branch to each repo in turn, but actually Git allows pushing to multiple repos in one go.

If in doubt about what git is doing when you run these commands, just

	set ideajoin
	set showcmd

	" integrate with system clipboard
	set clipboard=unnamed,ideaput,unnamedplus

	" easy tool window
	nnoremap \p :action ActivateProjectToolWindow<CR>
	nnoremap \c :action ActivateCommitToolWindow<CR>
	nnoremap \r :action ActivateRunToolWindow<CR>

	// Remap 'Tab on the right' with `gt`/`K`
	api.map('gt', 'R');
	api.map('K', 'R');
	// Remap 'Tab on the left' with `gT`/`J`
	api.map('gT', 'E');
	api.map('J', 'E');
	// Remap 'Back in hisotry' with `gT`/`J`
	api.map('H', 'S');
	// Remap 'Forward in hisotry' with `gT`/`J`
	api.map('L', 'D');

	#!/bin/bash

	remote=origin ; for brname in `git branch -r \| grep $remote \| grep -v /master \| grep -v /HEAD \| awk '{gsub(/^[^\/]+\//,"",$1); print $1}'`; do git branch --track $brname $remote/$brname \|\| true; done 2>/dev/null
