Install and use pip on macOS without sudo / admin access

Most recently tested on macOS Sierra (10.12.6)

1. Download the installation script; curl https://bootstrap.pypa.io/get-pip.py -o ~/Downloads/get-pip.py
2. Run the installation, appending the --user flag; python ~/Downloads/get-pip.py --user. pip will be installed to ~/Library/Python/2.7/bin/pip
3. Make sure ~/Library/Python/2.7/bin is in your $PATH. For bash users, edit the PATH= line in ~/.bashrc to append the local Python path; ie. PATH=$PATH:~/Library/Python/2.7/bin. Apply the changes, source ~/.bashrc.
4. Use pip! Remember to append --user when installing modules; ie. pip install <package_name> --user

10 Scala One Liners to Impress Your Friends

Here are 10 one-liners which show the power of scala programming, impress your friends and woo women; ok, maybe not. However, these one liners are a good set of examples using functional programming and scala syntax you may not be familiar with. I feel there is no better way to learn than to see real examples.

Updated: June 17, 2011 - I'm amazed at the popularity of this post, glad everyone enjoyed it and to see it duplicated across so many languages. I've included some of the suggestions to shorten up some of my scala examples. Some I intentionally left longer as a way for explaining / understanding what the functions were doing, not necessarily to produce the shortest possible code; so I'll include both.

1. Multiple Each Item in a List by 2

The map function takes each element in the list and applies it to the corresponding function. In this example, we take each element and multiply it by 2. This will return a list of equivalent size, compare to o
