Problem

I have two Github accounts: oanhnn (personal) and superman (for work). I want to use both accounts on same computer (without typing password everytime, when doing git push or pull).

Solution

Use ssh keys and define host aliases in ssh config file (each alias for an account).

How to?

1. Generate ssh key pairs for accounts and add them to GitHub accounts.

When unsing docker compose you can have a problem with the order of dependent linked containers

The solution is to start a script which tries to access a service and waits until it gets ready before loading your program

Slices of Slices

Slices of slices behave a little differently than I expected.

// Style 1
// Export all manually

// Good: Calling functions inside the module is convenient
// Bad:  module.exports becomes verbose and it's tedious to add new functions

# 1) Create your private key (any password will do, we remove it below)

$ cd ~/.ssh
$ openssl genrsa -des3 -out server.orig.key 2048


# 2) Remove the password

$ openssl rsa -in server.orig.key -out server.key

Figure out a good standard for how to use the HTTP response codes in a 'truly RESTful' (Now called 'Hypermedia API' apparently) way.

Summary

• HTTP Methods (Verbs)
  • Spec: http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html
  • OPTIONS: Display which HTTP methods can be called on a resource.
  • GET: Just get a resource.
  • PUT: Update a resource
• PATCH: Partial update of a resource (not universally supported)
