Rough Notes about CQRS and ES

Once upon a time…

I once took notes (almost sentence by sentence with not much editing) about the architectural design concepts - Command and Query Responsibility Segregation (CQRS) and Event Sourcing (ES) - from a presentation of Greg Young and published it as a gist (with the times when a given sentence was heard).

I then found other summaries of the talk and the gist has since been growing up. See the revisions to know the changes and where they came from (aka the sources).

It seems inevitable to throw Domain Driven Design (DDD) in to the mix.

How to configure multiple deploy keys for different private github repositories on the same computer without using ssh-agent

Let's say alice is a github.com user, with 2 or more private repositories repoN. For this example we'll work with just two repositories named repo1 and repo2

https://github.com/alice/repo1

https://github.com/alice/repo2

You need to be to pull from these repositories without entering a passwords probably on a server, or on multiple servers.

# This enables a publicly available server to forward connections to your computer behind a NAT.
# So if you access http://xx.xx.xx.xx:8080/ on your browser, traffic is redirected to your machine behind a NAT.

# on your local host, type:
ssh -R xx.xx.xx.xx:8888:localhost:80 [email protected]

# now wait for your shell, and type:
socat TCP-LISTEN:8080,FORK TCP:127.0.0.1:8888

# This command outputs nothing, just keep it running. While you don't ^C, your tunnel is up and running!
