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

sudo apt-get install libasound-dev portaudio19-dev libportaudio2 libportaudiocpp0
sudo apt-get install ffmpeg libav-tools
sudo pip install pyaudio

Workflows (States) in Django

I'm going to cover a simple, but effective, utility for managing state and transitions (aka workflow). We often need to store the state (status) of a model and it should only be in one state at a time.

Common Software Uses

• Publishing (Draft->Approved->Published->Expired->Deleted)

ELK (Elasticsearch Logstash Kibana)

Though we're focused more on server setup procedure in this document, I will still give a very brief explanation in laymen terms for ELK. To those who are starting new in this stack, must have already heard of MVC (Model View Controller), so take it like this:

• Model => Elasticsearch (for Storage, Indexing & Search)
• View => Kibana (for DataViz & G-Man, yeah the one in half life 😏)
• Controller => Logstash (For Logs & Filtering)

git log --oneline 7de7970..master

OR

git log --oneline 7de7970..4cb34a9

Above command will give all logs between commit A and commit B including commit A and commit B.
