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

After automatically updating Postgres to 10.0 via Homebrew, the pg_ctl start command didn't work.
The error was "The data directory was initialized by PostgreSQL version 9.6, which is not compatible with this version 10.0."

Database files have to be updated before starting the server, here are the steps that had to be followed:

# need to have both 9.6.x and latest 10.0 installed, and keep 10.0 as default
brew unlink postgresql
brew install postgresql@9.6
brew unlink postgresql@9.6
brew link postgresql

Differences between team gemfile and your preferences

The solution for the above problem is to have a different gemfile that you run your rails app against. It can be easily done by adding some terminal aliases to use a different gemfile file. I made that in the current configuration and it works well.

это из этой книжки классификация различных парадигм Если присмотришься, то увидишь, что Oz поддерживает большинство вариаций (с этой целью его и конструировали, чтобы можно было наглядно продемонстрировать различные подходы в одном языке)
