Code Review

Polyglot Unconference 2018

John, from Mobify kickoff presentation

Initial cofounder of mobify, did a lot of early development, solo. Added more developers to the team, got more experience looking at others' code. Learned a lot of things by looking at others' code. As code review policy brought in, junior developers picked stuff up faster.

Simple automated GIT Deployment using GIT Hooks

Here are the simple steps needed to create a deployment from your local GIT repository to a server based on this in-depth tutorial.

How it works

You are developing in a working-copy on your local machine, lets say on the master branch. Most of the time, people would push code to a remote server like github.com or gitlab.com and pull or export it to a production server. Or you use a service like deepl.io to act upon a Web-Hook that's triggered that service.
