Getting started

Getting started is the hardest. This repo contains some hints for your first steps with any given technology.

We usually use the command line, git as a versioning control system and code editors for our coding projects. Here we collect, what you need to install on your computer to get started.

• Editors
• Command Line
  • Mac Terminal
• Versioning Control
  • Git on Mac
  • Git in Windows
• Languages
  • R
• Programming Environments
  • Jupyter Notebooks
• Frameworks
  • Flask

Editors

A couple of our members use Sublime Text [1] and vim on the command line. You can also use PyCharm [2] as well as other editors of course.

Sublime Text works for me well for both pure web HTML / JavaScript projects as well as for Python. The free edition of Sublime has a little window popping up, which reminds you to purchase a license, which can get annoying at some point.

The free PyCharm Community edition works well with Python but I wouldn't recommend it for web projects dealing with JavaScript libraries like ReactJS for instance.

Git

On a Mac

Following those instructions [3] you need to type the command

git --version

in a command line and if git isn't installed on your system yet, a dialog pops up which lets you install it as part of Xcode command line tools.

In Windows

Please open the instructions to install git for Windows [4] You might want to install Tortoise Git [5], too to use Git from the context menu when you right-click in a folder.

Command line

Mac terminal

Please follow the instructions here [7] to install Homebrew. It should be the following command, which you need to run:

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Then install python 3.6 using brew:

brew install python

With

python --version
which python

you can check the version and the path of your python installation.

On a Mac, I find iterm2 [6] a great tool, it's like an advanced command line. There are also some instructions in the web, what you can add to the file

.bash_profile

in your home directory, so you can see on which git branch you are when you are in a folder which belongs to a repository. I added the following lines to my bash_profile file:

# Git branch in prompt.
parse_git_branch() {
    git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/ (\1)/'
}
export PS1="\u@\H \w\[\033[32m\]\$(parse_git_branch)\[\033[00m\] $ "
